Because the height of the shielding container 500 is about 6m and the space formed by the outer cylinder 503 and the thermally conductive sheet 508 is very narrow, it is very difficult to perform welding by hand. Therefore, it is necessary to make a dedicated self-propelled welding machine. The welding machine is operated by remotely separating the welding machine while walking in the space, which makes the welding operation very troublesome. Especially, in the case of an assembly workshop with only a traditional welding device, 'because the assembly of the shielding container is difficult', and a special welding is required. The introduction of the machine and its technical guidance, so it can only apply the Chinese National Standard (CNS) A4 specification (210X297 mm) -5- 529040 A7 B7 on a specific paper size. 5. Description of the invention (3) Assembly in the assembly workshop. This problem is particularly profound for foreign countries with less developed assembly technology. (Please read the precautions on the back before filling out this page.) Therefore, the present invention A first object is to provide a shielded container and a method for manufacturing a shielded container that can easily assemble the shielded container. The problems of the next conventional shielded container will be described below. Figure 4 丨 shows a conventional shielded container Fig. 42 is a sectional view in the axial direction of the shielded container shown in Figure 41. The shielded container 1 500 is used in a fuel assembly and is housed in a stainless steel plutonium shielding T line. Inside the main body 1501 (not shown). On the outer periphery of the main body 1501, a plurality of strips 1502 are welded into a radial shape. The strips 1 502 are bent into a slightly V-shaped cross section, and the side edge 1 52 1 is welded to the main body 1 50 1, and the other side edge 1 5 22 is welded by the polygonal curve 1 523 formed at the corner of the adjacent strip 1502. Moreover, the strip 1 502 is The collapse heat transmitted by the plutonium body 1501 is released to the outside, and is made of a material with high thermal conductivity, such as a copper plate. Moreover, a resin 1 503 for absorbing neutrons fills the space formed by the strip 1502. Economy Of Intellectual Property Bureau Fi is printed on the outside of each strip 1 502, and a sheet 1 504 for heat radiation is welded. The sheet 1 504 is a V-shaped and the tooth surface is curved. The used crushing heat of the fuel assembly is first It is transmitted to the main body 1 50 1. Since the main body 1 50 1 is fused with the strip 1 502, the collapse heat is transmitted from the main body 1501 to the strip 1502, and the exposed surface of the strip 1 502 and The sheet 1504 is released to the outside. However, in the conventional shield container 1 500 described above, since the strip sheet 1 502 is welded to the plate-shaped sheet 1 504, a temperature is generated on the outer surface, and there is no uniform heat release. The problem. In other words, it will produce: Applicable Chinese National Standard (CNS) A4 specification (210 X 29 * 7 mm) to the paper size of the film -6- 529040 A7 B7 V. Description of the invention (4) (Please read the note on the back first Please fill in this page again.) The temperature of the joining part of 15.04 is high, but the temperature distribution of the strip 1 504 between the sheet 1 504 and the sheet 1504 is low, which makes the heat release efficiency not good. Therefore, a second object of the present invention is to provide a shielded container capable of improving heat radiation efficiency. [Disclosure of the Invention] In order to achieve the above-mentioned object, the shield container of the present invention is directed to a puppet body having a cage having a plurality of grooves for accommodating a used fuel assembly contained therein, and a plurality of thermally conductive sheets are provided in the puppet body. The outer cylinder is mounted on the outer periphery of the heat conducting sheet, and the neutral container is provided in a shielded container in the space between the heat conducting sheet and the outer cylinder, wherein the outer cylinder constitutes a plurality of band-shaped members A and B. Welding is performed on the end edge portion, and the end edge portions remain on both sides of one band-shaped member A to weld the heat conductive sheet, and other band-shaped members B adjacent to the band-shaped member A are fused to respective end edges. Near the Ministry of Economic Affairs, Intellectual Property of the Ministry of Economic Affairs, and Employee Consumer Cooperative Co., Ltd. Since the heat sink is welded to the edges of the band-shaped member A with the end edges remaining, the band-shaped members A and B are welded to each other at the end edges. In the vicinity of the portion, the welded portion of the band-shaped member A and the band-shaped member B and the welded portion of the heat conductive sheet and the band-shaped member A can be separated.

The method is characterized by having a process of unitizing a ring-shaped heat-conducting sheet by fusing the ring-shaped heat-conducting sheet with the end edges remaining on both sides of one ring plate A, and Body, the process of welding the two units from the outside of the unit with the aforementioned thermally conductive sheet, and the process of welding the other ring plate B between the ring plate A and the ring plate A of the adjacent unit from the outside . The Intellectual Property of the Ministry of Economic Affairs ^ 7 The manufacturing method for printing this shielded container by the employee consumer cooperative, first of all, these welding operations can be easily performed by welding the ring plate A and the thermal conductive sheet. Then, although the The heat-conducting sheet is welded to the cymbal body, but because the cross-section of the unit is T-shaped, its two sides are open, and welding operations can be performed from the outside. When welding the ring plates A and A, it is also from the outside. Therefore, it is not necessary to perform welding in a narrow space using a dedicated welding machine as is conventionally known, and since the welding can be performed from the outside, the shielding container assembly operation can be easily performed. 'Furthermore, the method for manufacturing a shielding container of the present invention It is characterized by having a process of unitizing a ring-shaped heat-conducting sheet by fusing the ring-shaped heat-conducting sheet with the end edges remaining on both sides of one ring plate A, and forming a ring-shaped forming tree.

Next, although at least two units are welded at predetermined intervals from the outside of the unit toward the axis, the resin is also placed in the same manner as above. Further, the molding resin is arranged between adjacent units, and the ring plate B is welded from the outside to the ring plate A and the ring plate A of the unit. Therefore, it is not necessary to use a dedicated welding machine to perform welding in a narrow space as is conventionally known, but it is possible to completely weld from the outside. In addition, the resin can be easily disposed. As a result, the shielding container can be easily assembled. Moreover, the method for manufacturing a shielded container according to the present invention is the same as the method for manufacturing a shielded container described above, wherein the aforementioned unit and / or ring plate B has a more divided structure in the circumferential direction, and is separately welded to the cymbal body. . The unit and / or the ring plate B can be divided by the circumferential direction, so that the Chinese paper standard (CNS) A4 specification (210X 297 mm) can be applied from the paper size. -18- 529040 A7 B7 V. Description of the invention (16) Unit. Side mounting unit, ring plate B. Moreover, it is easy to arrange the molding resin in a unit or between units. Therefore, the shielding container can be easily assembled. Furthermore, the shield container of the present invention is characterized by having a plutonium body inside the cage for accommodating radioactive materials such as used fuel assemblies, and a plurality of plate-like members provided around the plutonium body. One part is connected to the body, the other part forms the outer part of the shield container and has a singular or plural mountain or valley part. The other part is connected to the adjacent plate-shaped member to absorb the neutrons. The material fills the space formed by the plate-like member. The collapse heat from the used fuel assembly is transmitted from the plutonium body to the plate-like member, and is radiated from the outside of the shielded container. Since a mountain-shaped portion or a valley-shaped portion is formed on the outer surface of the shielded container, the heat radiation area is larger than that of a conventional shielded container simply formed into a cylindrical shape, and the heat radiation is performed efficiently. However, the plate-like member may be manufactured by bending a plate material, or may be manufactured by extrusion molding. In particular, by compounding the neutral absorbing material and the honeycomb material, and connecting the honeycomb material to at least the concrete body, even if the thermal conductivity of the neutral absorbing body is low, heat can be conducted through the honeycomb material. In addition, by combining the aforementioned neutron-absorbing material and a plurality of heat conductors, the thermal conductivity can also be improved. Next, the honeycomb material or the heat-conducting system is made of aluminum or aluminum, and the plate-shaped member is made of iron, aluminum, or copper, and the heat-conducting function can be maintained in the honeycomb material heat-conducting body.

當組裝外筒105及導熱片107時，藉由隨著上述順序， 而不需要由外筒105及導熱片107所構成的狹長空間內的熔 接。也就是S兌’在上述參考例中，雖在形成於外筒5 0 3及導 熱片508的空間內讓自走式熔接機行走來進行熔接，但藉由 隨著上述順序組裝外筒1 05及導熱片1 07，可以使全部的熔 接由外部進行，即使無專用的熔接機，通常的熔接設備也 可以組裝屏蔽容器。因此，屏蔽容器的組裝作業變得非常 容易。 經濟部智慧財產局員工消費合作社印製 回到第1圖及第2圖，收容屏蔽容器100的使用過燃料集 合體，因爲含有核分裂性物質及核分裂生成物等，不但發 生放射線並且產生崩壞熱，所以有必要確實地維持貯藏期 間（60年左右）中的屏蔽容器100的除熱機能、遮蔽機能及臨 界防止機能。此第1實施例的屏蔽容器1 00中，機械加工胴 本體1 0 1的凹處1 0 2內使籠1 3 0的外周面可呈密合狀態（幾乎無 空間）插入，並且，將導熱片107設在胴本體101及外筒105之 間。因此，來自於燃料棒的熱，通過籠或被充塡的氦氣傳 導至胴本體101，而成爲主要通過導熱片107而從外筒105被 放出。從以上，可以提高從籠130的導熱率’且可有效率地 進行崩壞熱的除熱。 且，由使用過燃料集合體所發生的r線’係被由碳鋼 本紙張尺度適用中國國家標隼（CNS ) A4規格（210X297公釐） -30- 529040

有硼的鋁合金，所以可以防止吸收中性子而達到臨界。 以上，依據此第1實施例的屏蔽容器100的話，將外筒 105作成分割構造並複數製作以帶狀構件105a及導熱片107 構成的單元l〇5c，將此以預定間隔對於胴本體101從外側熔 接，並且相鄰接的帶狀構件1 05a之間全部橫跨帶狀構件 1 05b並從外側熔接，而不需要在狹長空間內熔接。因此， 可以容易進行熔接作業，而不需要特別的專用熔接機。且 ，因爲可以利用廣泛被慣用熔接設備進行屏蔽容器100的組 裝，所以可以在大部分的企業內容易進行組裝。 經濟部智慧財產局員工消費合作社印製 接著，因爲機械加工胴本體101的凹處102內而可由幾 乎密合狀態將籠130的外周面插入，所以可以提高籠130的 導熱率。特別是，介由設在籠外周面的導熱板3 1 8有效率地 將崩壞熱傳到胴本體1 〇 1，且，藉由在籠1 30的角剖面部分 301b使一部分面接觸在胴本體101，可以確實地保持籠130 並且提高導熱率。而且，藉由將暫代管308插入空間S，使 導熱率更佳。然而，在上述結構中，當然即使省略導熱板 318,也是可以提高某些程度的導熱率。 且，因爲可以消除凹處1 02內的空間，所以可以輕小且 輕量化胴本體101。然而，即使這種情況，也不會減少使用 本紙張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐） -31

[外筒及導熱片的變形例] 第1 2圖係顯示外筒及導熱片的變形例的說明圖。如此 ，也可以將導熱片2 1 0傾斜。其他的結構係與上述屏蔽容器 相同。因爲藉由將導熱片210傾斜設置使從使用過燃料集合 體的中性子的放出方向必有樹脂1 06，所以可以抑制中性子 貫通導熱片210而朝外部漏出。然而，在同圖中，導熱片 2 1 0的傾斜雖相互地交叉，但也可以將全部的導熱片從容器 中心呈放射狀配置，也可以只朝一方向傾斜（無圖示）。 且，如第13圖所示，將帶狀構件21 lb重疊在帶狀構件 211a的端緣地熔接也可以。這種情況也利用帶狀構件21 la 及導熱片107製作剖面C字形狀的單元並分別熔接在胴本體 101，且將帶狀構件21 lb全部熔接在相鄰接的帶狀構件21 la 之間。即使這種結構，也與上述同樣可以容易組裝屏蔽容 器，且利用分離熔接部212、213而可以防止熱影響部集中 於局部。且，因爲可以省略帶狀構件端緣的段加工及倒角 加工而可以使外筒211的構造簡單。 且，在第14圖所示的結構中，將導熱片214本體彎折成 (請先閲讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐〉 -32- 529040 A7 B7 五、發明説明（30 )

集中於局部。而且，因爲將銅製的導熱片2 14面接觸於帶狀 構件1 05a所以有效率地將屏蔽容器內部的崩壞熱傳達至外 筒1 05，而可以朝外部放熱。然而，放熱路線以圖中一點鎖 線表示。 [第2實施例] 經濟部智慧財產局員工消費合作社印製 第1 5圖係顯示本發明的第2實施例的屏蔽容器的說明圖 。此屏蔽容器的特徵爲：外筒2 1 6成爲剖面呈山形狀。藉由 將導熱片107熔接在被彎曲形成山形狀的帶狀構件2 1 6a的兩 端緣（熔接部205)被單元化，並被熔接在突出部201上（熔接 部206)。且’帶狀構件216b也同樣地被彎曲成形，將該帶 狀構件21 6b的段部203嵌入帶狀構件216a的段部202，並從 外側熔接（熔接部204)。在帶狀構件216a、216b的內側面， 設有蜂窩狀材。在帶狀構件216a、216b及導熱片107的空間 中，充塡有進行中性子的吸收的樹脂。 即使這種結構，因爲可以全部從外側進行熔接作業， 所以與上述同樣可以容易地進行屏蔽容器的組裝，且藉由 分離熔接部204、205，可以防止熱影響部集中於局部。且 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） -33- 529040 A7 B7 五、發明説明（31 ) (請先閲讀背面之注意事項再填寫本頁) ，因爲帶狀構件216a、216b形成山形狀，所以外筒21 6的表 面積變大而可以提高放熱效果。且，在使複數的板狀的放 熱片對於外筒突出的屏蔽容器中，雖不容易淸掃放熱片和 外筒的角落，但此山形狀的外筒2 1 6的情況，因爲無狹小的 角落，所以容易進行外筒表面的淸掃。然而，作成谷形狀 也具有同樣的效果（無圖示）。 且，如第1 6圖所示，也可以將帶狀構件2 1 7的端緣載置 於導熱片1 〇7的端緣頂部，並且與相鄰接的帶狀構件2 1 7的 端緣接合，並熔接該接合部分（熔接部2 1 9)。在帶狀構件2 1 7 的端緣形成倒角。藉由將外筒21 8作成這種山形狀，就可以 提高屏蔽容器的放熱性能。 [第3實施例] 經濟部智慧財產苟員工消費合作社印髮 第17圖係顯示本發明的第3實施例的屏蔽容器的說明圖 。此外筒220之特徵爲：將導熱片107熔接在帶狀構件l〇5a 的中央，使成爲剖面T字形狀的單元220a。熔接順序與第1 實施例略相同，首先，將導熱片107熔接在帶狀構件l〇5a而 成爲單元220a。此導熱片107及帶狀構件105a的熔接，可以 從片側進行，且爲了確保強度也可以從兩側進行（熔接部 222)。接著，將該單元220a以預定間隔熔接在胴本體1〇1。 然而，突出部201設在胴本體101，導熱片107被熔接在突出 部201上。且，前述熔接，爲了確保強度而從導熱片107的 兩側進行。而且，將帶狀構件1 05b全部嵌入熔接在相鄰接 的帶狀構件105a之間（熔接部204)。 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） -34- 529040 A7 B7 五、發明説明（32 ) 即使這種結構，因爲不需在狹長空間內的熔接’可將 全部的熔接作業從外側進行，所以與上述同樣可以容易地 進行屏蔽容器的組裝。且，因爲藉由將剖面作成τ字形狀 ，而可以使熔接部222、204的距離分離比上述第1、2實施例 更大的距離，所以更可以防止熱影響部集中於局部。然而 ，如第1 8圖所示，將導熱片224的端部彎曲加工而作成剖面 呈L字形狀，且對於帶狀構件1 〇5a面接觸也可以。這種情 況，導熱片224及帶狀構件l〇5a的熔接，係以導熱片224的 角緣部與帶狀構件l〇5a熔接（熔接部223)。 如此的話，因爲可以將導熱片224載置於帶狀構件l〇5a 來進行熔接，所以組裝變得容易。且，因爲使導熱片224面 接觸在帶狀構件105a，所以可有效率地將屏蔽容器內部的 崩壞熱傳達至外筒220並放熱。然而，放熱路線以圖中一點 鎖線表示。 第19圖係顯示第17圖的屏蔽容器的變形例。此屏蔽容 器之外筒225由複數的帶狀構件226所構成，並以其之中央 部分別與導熱片107熔接（熔接部227)，而成爲剖面爲T字形 狀的單元228。此外筒225的組裝，首先將單元228a的導熱 片107從片側熔接在胴本體1〇1(熔接部229a)。接著，將單元 228b的導熱片107從開放的片側熔接在胴本體1〇1(熔接部 229b)，並且，將帶狀構件226a、226b彼此之間熔接（熔接部 230a) ° 接著，同樣地將單元228c的導熱片107從開放的片側熔 接在胴本體101(熔接部229c)，並且，將帶狀構件22

229d地將導熱片107熔接在胴本體101，且將熔接部230c帶 有帶狀構件226c、226d地熔接。即使如此’因爲可以將所 有的熔接從外側進行，而不需要在狹長空間的熔接，所以 可以容易地進行屏蔽容器的組裝作業。且，因爲熔接部2 3 0 及熔接部227分離的很開，所以可以防止熱影響部集中於局 部。 [第4實施例] 經濟部智慧財產局員工消費合作社印製 第20圖係顯示本發明的第4實施例的屏蔽容器的外筒的 平視圖。在上述實施例中，雖熔接接合複數的帶狀構件來 形成外筒，但也可以作成將構成外筒105的帶狀構件l〇5a連 結在屏蔽容器軸方向端部的形狀。導熱片1〇7(圖中點線所示 )，對於1個板構件23 1以預定間隔熔接4個。而且，帶狀構件 l〇5a與導熱片107具有預定間隔地熔接在胴本體，且帶狀構 件105b嵌入並熔接於其之缺口部l〇5d及相鄰接的板構件231 的間隔內。然而，在與連結部233相對向的位置，因爲未配 置導熱片107，所以不會妨礙熔接作業。 且，如第2 1圖所示，也可以連結相鄰接的板狀構件234 及連結部235來將板狀構件234作成C：字形狀。在此結構中 ，將帶狀構件l〇5b嵌入熔接於由板狀構件234所形成的缺口 部236。由此，形成外筒237。 [第5實施例]

軸方向而熔接形成。環狀的單元402，將帶狀的板形成環狀 而作爲環板403，並將環狀的導熱片404熔接在該內周面（熔 接部405)。此單元402藉由熔接在將導熱片404設在胴本體 101的周方向的突出部406上而被固定。且，複數的單元402 被安裝在胴本體101，使相鄰接的單元402的環板403的周緣 彼此之間被熔接（熔接部407)，在藉由熔接該環板403的周緣 彼此所形成的空間，配置有預先使用模型而固化的環狀的 樹脂408。 經濟部智慧財產局員工消費合作社印製 組裝此屏蔽容器400時，首先，最前面的單元402a插入 胴本體101，再將導熱片404熔接在胴本體101的突出部406。 接著，將環狀的樹脂408a插入胴本體101，將約一半收入已 熔接固定的單元402a。接著將下一個單元402b插入胴本體 101，並且，將前述樹脂408a的約一半收入其之內部，並熔 接最前面的單元402a的環板403及下一個的單元402b的環板 403(熔接部407)。這時，單元402b的環板403的熔接只從開 放的片側進行（熔接部409)。只要將此返覆進行數次，並安 裝最後面的單元402，就可完成外筒401的組裝。然而，不 容易插入環狀的樹脂408的情況時，將環狀的樹脂408朝周 方向分割，並將圓弧狀的樹脂408x收容於前述空間也可以 。然而，蓋410設在外筒401的兩側。 如此結構的話，因爲不需要在狹長空間內的熔接，而 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） -37 —— 529040 A7 B7 經濟部智慧財4局員工消費合作社印製 五、發明説明（35) 可以完全從外側熔接，所以可以容易地進行熔接作業，而 不需要特別的專用熔接機等。且，因爲可在被廣泛慣用的 熔接設備進行屏蔽容器400的組裝，所以可以在大部分的企 業容易地進行組裝。而且，因爲熔接部405及熔接部407分 離，所以可以防止熱影響部集中於局部。 第24圖係顯示本發明的第5實施例的變形例的組裝圖。 第25圖係顯示第24圖所示的屏蔽容器的一部剖面圖。此屏 蔽容器450之特徵爲：將外筒451的單元452作成圓弧狀的2分

胴本體11 ο 1。而且，在二次蓋111 〇及二次蓋m 1之間分別設 有金屬墊片，以保持內部的密封性。在屏蔽容器本體的兩 側，設有供吊下屏蔽容器11 00用的耳軸111 7。然而，運搬屏 蔽容器1100時，係將緩衝體1118安裝在其之兩側。 胴本體1 101的內面，成爲配合所使用的籠13〇〇的外形的 形狀，且該籠1 300的外面對於胴本體1101成爲略密合狀態（ 但是，實際上會產生微小的間隙）。然而，不需要將胴本體 1101的內面幾乎完全配合籠1 300的外形，也可以作成不接觸 籠1 300的外面的一部分的形狀，而這些比率是可以考慮導 熱率來作適當的設計。 經濟部智慈財產局員工消費合作社印製 在前述籠1 300中，係可以使用：束有在鋁或鋁合金粉 末添加具有中性子吸收性能的硼或硼化合物的粉末的鋁合 材或鋁合金製的角管而構成複數的槽者、積層形成具有複 數槽的鑄造品（相當於第26、27圖所示的籠）者、將鋁複合材 或鋁合金製的矩形板材垂直於溝並將其呈折點心狀地積層 者等。然而，中性子吸收材，除了硼之外，也可以使用鎘 。且，在此實施例的籠1 300中，雖可以收容33個使用過燃 料集合體（PWR用），該數不一定爲33。且，當然也可以使用 於BWR用的屏蔽容器。 本纸張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） -42- 529040 A7 _______B7_ 五、發明説明（4〇 ) (請先閲讀背面之注意事項再填寫本頁) 且，籠1 300的外形因爲接近8角形，所以胴本體1101的 內面也大致爲8角形，且使與各面相對向地將胴本體11 〇 1的 外面形成8角形。由此，胴本體1101的厚度全體成爲略均一 ’而無多餘的厚度，而可以謀求輕量化。且，r線遮蔽性 能可在必要充分的範圍內被確保。胴本體11 〇 1的內面及外 面的加工，係使用專用的機械加工裝置進行。詳細請參照 本案申請人之日本特願平1 1-2493 14號的公報。然而，在此 實施例中，雖將一次蓋1 1 1 0的形狀作成8角形，但不限定於 此。也就是說，也可以配合籠1 300的外形而將胴本體1101的 形狀作成10角形或12角形等（無圖示）。 經濟部智慧財產苟員工消費合作社印製 但是，將使用過燃料集合體收容於屏蔽容器11 00內時 ，將屏蔽容器1100沈入水池，而將使用過燃料集合體收容 於水中。因此，因爲放射性物質會附著在屏蔽容器1100的 周圍，所以當從水池拉起時，有必要將其淸除。但是，在 上述習知的屏蔽容器1 500中，因爲將楔形狀的片1504熔接在 條片1 502，所以淸除用的刷子不容易達到根部，即使用噴 水等的洗淨也會有死角，所以有必需徹底地洗淨等的淸除 不易的問題點。 對於此，此實施例之特徵，係爲具有：配置有供收容 使用過燃料集合體至內部用的籠1 300的胴本體1101、及設在 胴本體1101的周圍的複數板狀構件1201，且該板狀構件1201 的一部分接在胴本體1101，其他的一部分構成屏蔽容器11 00 的外面並具有單數或複數的山形部1 207(或谷形部），且其他 的一部分接合在相鄰接的板狀構件1201，並將樹脂1106充塡 本纸張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐） -43-

核分裂性物質及核分裂生成物等，且所產生放射線的同時 也會產生崩壞熱，所以有必要確實維持屏蔽容器11 00的貯 藏期間中的除熱機能、遮蔽機能及臨界防止機能。在此屏 蔽容器1100中，將複數的板狀構件1201設在胴本體1101的周 圍，藉由將設在由板狀構件1201所形成的空間1 206的蜂窩狀 材1210、及將形成屏蔽容器1100外面的板狀構件1201作成山 形狀來擴大放熱面積，而可以有效率地將由使用過燃料集 合體所產生的崩壞熱傳熱並放出。 由使用過燃料集合體所產生的崩壞熱，通過籠1 300或 被充塡的氦氣而傳導至胴本體1101。接著，通過具有內部 片機能的板狀構件1201及蜂窩狀材1210而將崩壞熱傳達至屏 蔽容器1100。特別是前述蜂窩狀材1210，因爲是導熱性佳的 鋁製或銅製所以可有效率地吸收來自於胴本體1101的熱’ 並將其傳到板狀構件1201，而從屏蔽容器外面朝外部放熱 。由以上，因爲可以有效率地進行崩壞熱的除熱，所以只 要崩壞熱量相同的話，就可以將屏蔽容器內的溫度保持比 習知例更低。 .然而，由使用過燃料集合體所產生的r線’係在由碳 (請先閱讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐） -44- 529040 A7 B7 五、發明説明（42 )

金，所以可以防止吸收中性子而使使用過燃料集合體達到 臨界。 以上，依據本實施例的屏蔽容器1100的話，因爲將板 狀構件1201安裝在胴本體11〇1，且將山形部1 207設在該板狀 構件1 20 1中形成屏蔽容器外面的部分，又將鋁製的蜂窩狀 材1210放入由該板狀構件1201所形成的空間1206，所以可以 提高崩壞熱的導熱效率。而且，依據此實施例的屏蔽容器 1100的話，因爲不需如習知的需將片1504從外周面熔接，所 以有製造容易的優點。然而，在上述屏蔽容器11 00中，雖 收容使用過燃料集合體，當然也可以收容之外的放射性物 質。 經濟部智慧財凌局員工消費合作社印製 第31圖係顯示本實施例的變形例。在此屏蔽容器中， 將碳鋼製的板狀構件1201設在胴本體1101的周圍，且將由鋁 板（或者是銅板或石墨片）所組成的易導熱板1400貼附在該板 狀構件1201的兩面。且，在由板狀構件1201所形成的空間內 ，只充塡樹脂1 106。然而，在該樹脂1106的外側及板狀構件 1201之間，形成膨脹部分1401(無圖示）。然而，也可以將前 述易導熱板1400只設在板狀構件1201的片面。而且，爲了提 高集熱效率，如第32圖所示，也可以延伸前述易導熱板 本纸張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐） -45- 529040 A7 B7 五、發明説明（43) (請先閲讀背面之注意事項再填寫本頁) 14.00(延長部1402)，使與胴本體1101面接觸。這種情況，因 爲可以有效率地從延長部1402導熱至易導熱板1400，所以可 以將樹脂1106的溫度保持於較低，而可以防止樹脂1106的品 質劣化。 在上述結構中，主要利用易導熱板1400(第32圖的情況 時，包含易導熱板1400的延長部1402)進行崩壞熱的傳熱。 然而，即使使用上述蜂窩狀材1 2 1 0的情況，也可以將易導 熱板1400貼附在板狀構件1201。由此，更可以提高屏蔽容器 的導熱率。 易導熱板1400的形狀，不限定於上述的形狀。例如如 第33圖所示，也可以設置延伸至胴本體1 101的延長部1405。 如此，更可以提高來自於胴本體1101的集熱效率，而可以 將樹脂1106、胴本體1101的溫度保持更低。 經濟部智慧財產局員工消費合作社印製 且，如第34圖所示，也可以對於由耐熱性高的鐵等的 材料所組成的板狀構件1201的一部分，將中間材1406介在於 樹脂1106之間。中間材1406，係使用鋁板、銅板等的導熱性 佳者。且，在與胴本體11 0 1的接合部1 407，最好使用容易熔 接於胴本體1101的材料。例如：與胴本體1101相同的材料的 碳鋼或不銹鋼等。板狀構件1201及中間材1406以及接合部 1407，係在熔接於胴本體1101的前階段預先在別的場所先熔 接好。熔接係使用摩擦攪熔接或TIG熔接。第35圖係顯示 第3 4圖的一部分的放大圖。接合部1 4 0 7的端部，係形成熔 接用的倒角1407a。由此，因爲可以利用熔接的突出部1407b 擴大與胴本體1101的接觸領域，所以可以提高導熱性。 本纸張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐） -46- 529040

所以可以實現更佳的熱移動性。以鋁材構成的情況的話’ 可以將屏蔽容器1100輕量化。且，這種結構，因爲耐熱性 的要求較低，可以適合貯藏專用容器。 且，上述的板狀構件1201的形狀並不限定上述第27圖 所示的形狀。例如：如第37圖所示，也可以使用剖面呈Y 字形狀的板狀構件1250。該板狀構件1250，所以利用彎曲加 工或壓出加工成形。這種板狀構件1 250的情況，係將其腳 熔接在胴本體1101，且兩端緣與相鄰接的板狀構件1 250的端 緣1251接合。由此，利用複數的板狀構件1 250形成屏蔽容器 1100的導熱片及外面。這種情況，熔接部1 253位在山形部 1 252的稜線。然而，熔接部1 253的強度變低的情況時，也可 以將熔接部1 25 3設在山形部1252的中間（無圖示）。 經濟部智慧財產局員工消費合作社印製 且，如第38圖的（a)所示，也可以使用複數傘狀的板狀 構件1 260來形成具有谷形部1261的屏蔽容器。且，如第同圖 (b)所示，將剖面爲T字形狀的板狀構件1 270的外面形成波 形（波形部271)，將其端緣與相鄰接的板狀構件1 270的端緣 接合。即使如此，也可以獲得與上述同樣的效果。然而， 這些板狀構件1260、1 270，也可以由板金加工、壓出加工形 成0 本紙張尺度適用中國國家標隼（CNS

The machining of the inner surface of the recess 102 is performed by a special processing device described later for milling. 胴 body 1 0 1 The bottom plate 104 is a forged product made of carbon steel having an R-line shielding function. However, stainless steel other than carbon steel can also be used. The above-mentioned main body 101 and bottom plate 104 are welded together to ensure pressure resistance. The container is sealed with a metal gasket placed between the primary lid 110 and the cymbal body 101. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is printed between the cymbal body 101 and the outer tube 105, which is filled with a high content of hydrogen-rich hydrogen A resin 106 having a molecular material and a function of shielding neutrons. A plurality of copper heat-conducting sheets 107 for heat conduction are welded between the plutonium body 101 and the outer tube 105, and the resin 106 is injected in a flowing state through the guide. The space formed by the sheet 107 is cooled and solidified. However, it is also possible to dispose the honeycomb body made of aluminum or copper in the space and press the neutral shielding body into the honeycomb body (not shown). And, In order to uniformly radiate heat, it is better to set a higher density in the portion with more heat. A thermal expansion gap 108 of several mm is provided between the resin 106 and the outer tube 105. The cover portion 109 is formed by a primary cover. 110 and the secondary cover 111. This primary cover 1 1 0 is a disc shape made of stainless steel or carbon steel that shields the T line. This paper size applies to China National Standard (CNS) A4 (210X297) (Centi) -22- 529040 A7 B7 V. Description of the invention (2〇) And. Although the secondary cover 111 is also in the shape of a disk made of stainless steel or carbon steel, a resin 112 as a neutral shielding member is sealed on the secondary cover 111. The primary cover 11 〇 and the secondary cover 1 1 1 ′ are attached to the cymbal body 1 〇 1 with screws made of stainless steel or carbon steel. Further, metal gaskets are provided between the primary cover 110, the secondary cover 111, and the cymbal body 101, respectively, so as to maintain the internal tightness. On both sides of the shield container body, trunnions 117 for hanging the shield container 100 are provided. Then, the inside of the recess 102 is shaped to fit the outer shape of the cage 130. Fig. 3 is an explanatory diagram showing the structure of the cage. This cage 301 is structured so that a cut-in portion 3 1 2 is provided in a band-shaped plate-like member 3 10 having a through-hole 3 1 1 and overlaps the plate-like member 3 10 vertically and alternately. Thereby, a plurality of grooves 307 for storing the used fuel assembly are formed. The through-holes 311 are formed in the longitudinal direction of the plate-like member 310 in a cross section of "Day", and a plurality of communication holes (not shown) are formed in a rib 313 in the center thereof. The through-hole 311 is a through-hole 311 that communicates with another plate-like member 310 with a cut-in portion 312. Further, a communication hole 314 is provided on the end surface in the longitudinal direction of the plate-shaped member 310 so as to communicate with the through-holes 311 of the plate-shaped member 3 10 positioned above and below. In addition, concave portions 3 1 5 and convex portions 3 1 6 are formed on the upper and lower end edges of the plate-like member 3 1 0. The concave portions 3 1 5 and the convex portions 3 1 6 are positioned between the upper and lower plate-like members 3 1 0 (see FIG. 4). Accordingly, since a step can be prevented from occurring in the tank 307, the used fuel assembly can be smoothly stored in the tank 307. A convex portion 317 is formed at an end edge of the plate-shaped member 310. Further, as shown in FIG. 5 (a), since the worst can be generated at the end edge of the plate-like member 310 by providing the convex portion 317, the heat transfer plate 318 is straddled between the adjacent step differences. Thereby, the outer peripheral surface of the cage 130 is formed.

Description of the invention (21) (Please read the precautions on the back before filling in this page) The components 3 1 0 and the heat transfer plate 3 1 8 are made of boron-added aluminum or aluminum alloy. However, the mounting of the heat conducting plate 3 1 8 is not limited to the manner in which the convex portion 3 1 7 is provided as shown in the figure. For example, it may span the end edge of the plate-shaped member 3 1 0 and abut the heat-conducting plate 3 1 8 and may be fixed by spot welding or the like (not shown). Further, as shown in FIG. 5 (b), the heat-conducting plates 3 1 8 may be mounted on the respective plate-like members 310 without crossing the plate-like members 3 1 0 positioned above and below. In this case, as shown in FIG. 5 (c), the segments of the plate-like member 3 to 10 can be assembled into small pieces, and the cages 1 to 3 can be formed by laminating them. Therefore, insertion into the recess becomes easy, and removal of the cage 130 becomes easy. The outer shape of the cage 1 3 0 is such that its four faces 3 0 1 a are made flat by the heat transfer plate 3 1 8, and the other four faces 301 b have an angular cross-sectional shape. The internal shape of the recess 102 is a plane that is slightly in close contact with the plane portion (301a) of the cage 130, and the portion corresponding to the angular section (30 lb) of the cage 130 is slightly fitted to the shape, However, space S is left in the corner. Next, the space S is buried, and a temporary tube 308 having a triangular cross section is inserted. By using the temporary tube 308, the weight of the main body 302 can be reduced, and the thickness of the main body 302 can be uniformized. In addition, it is possible to suppress the non-adhesion of the cage 130 and securely fix it. Printed by the Intellectual Property of the Ministry of Economic Affairs / Employee Consumer Cooperative and 'as long as the internal of the temporary management 308 is sealed, even after the storage facility is filled with pure water, the pure water will not enter the temporary management 308, so Lightweight shielding container. In addition, by sealing the inside of the temporary tube 302, other materials can be filled inside. For example, helium gas can be introduced into the inside to facilitate the introduction of helium gas during storage. In addition, it is possible to improve the thermal conductivity during storage by using a sealed gas. However, when introducing helium, it is best to install a valve on one of the covers.

Description of Invention (22) (Please read the precautions on the back before filling this page) The trunnion 117 is directly attached to the body 10. At this time, the installation position of the trunnions 17 is preferably provided at the angular section 301b of the main body 101. In the angular section 301b, there is some space for the thickness of the 1 body 101 compared to the flat section 301a. Therefore, even if the trunnion seat is machined, it has little effect from the viewpoint of T-line shielding. In addition, although the resin 1 17a is filled into the trunnion 1 17, by filling the resin into the temporary tube 308 provided in the space S, the resin non-filled portion from the trunnion 117 can be partially prevented. The transmission of neutrons in 117b. Fig. 6 is a detailed explanatory diagram showing the structure of the outer cylinder and the heat transfer sheet. The tube 105 has a divided structure composed of a plurality of belt-shaped members 105 and 105b. The heat-conducting sheet 107 has both end edges of the band-shaped member 105a remaining, and is welded to both sides (welded portion 205) so that its cross-section becomes a "幵" shape. The heat conductive sheet 107 is welded to the protruding portion 201 (weld portion 206) on the surface of the cymbal body 101. The material of the protruding portion 201 is made of iron, which can improve the weldability with the heat conductive sheet 107 made of copper. The band-shaped member 105a and the heat-conducting sheets 107 and 107 are each a unit 105c having a C-shaped cross section, and are plurally welded to the surface of the main body 101 at a certain interval. Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, 8th Industrial Cooperative, Figure 7 is an enlarged view showing the fusion portion of Figure 6. The segment portion 202 is formed at both end edges of the band-shaped member 105a, and the segment portion 203 of the band-shaped member 105b is fitted into and welded to the segment portion 202 (welded portion 204). Further, it can be seen from the same figure that the heat-affected portion is prevented from being concentrated locally by partially separating the welded portion 204 between the band-shaped members 105a and 105b and the welded portion 205 of the heat-conducting sheet 107 and the band-shaped member 105a. This prevents thermal deformation of the outer tube 105 and the thermally conductive sheet 107 and reduces internal stress. The above welding can use TIG welding, MIG welding, etc. The paper size is applicable to China National Standard (CNS) A4 (210X 297 mm) -25- 529040 A7 B7 V. Description of the invention (23) Conventional welding method . However, inside the outer tube 105, an aluminum honeycomb material 207 for forming a hollow layer is mounted. (Please read the precautions on the back before filling out this page.) Figure 8 shows the flow chart of the method for manufacturing the plate-like member constituting the cage. First, 'produce aluminum or aluminum alloy powder by a rapid condensation method such as atomization method (stage S401), and prepare a powder of boron or a boron compound (stage S402)' and stir the particles with a turntable mixer or the like for 10 ~ 15 minutes (phase S403). The aforementioned aluminum or aluminum alloy may be pure aluminum alloy, aluminum-copper aluminum alloy, aluminum-magnesium aluminum alloy, aluminum-magnesium-silicon aluminum alloy, aluminum-zinc-magnesium aluminum alloy, aluminum-iron alloy or the like. As the boron or boron compound, B4C, B2 0 3 and the like can be used. Here, the amount of boron added to aluminum is preferably 1. 5 wt% or more and 7 wt% or less. If it is 1.5% by weight or less, sufficient neutron absorption performance cannot be obtained, and if it is 7% by weight or more, elongation with respect to stretching is reduced. Intellectual Property Bureau of the Ministry of Economic Affairs (printed by the Industrial and Consumer Cooperative) Next, the stirred powder is sealed in a rubber box, and CIP (Cold Isostatic Press) is used to uniformly apply high pressure from all directions at normal temperature to perform powder molding (S404). Molding conditions: The molding pressure is 200 MPa, the diameter of the molded product is 600 mm, and the length is 1,500 mm. By applying high pressure uniformly from all directions using CIP, a high-density molded product with uniform molding density can be obtained. The powder-molded product is vacuum-sealed in a tank and heated to '300 ° C (stage S405). The air and moisture in the tank are removed in this degassing process. In the next process, the molded product after vacuum degassing uses HIP (Hot Isostatic Press) re-forming (stage S406). HIP forming conditions: temperature 400 ° C ~ 450 ° C, time 30 sec, pressure 6000 tons, so that the diameter of the formed product is based on the paper standard and applies the Chinese National Standard (CNS) A4 specification (210X 297 (Mm) -26- 529040 A7 B7 V. Description of Invention (24) (Please read the notes on the back before filling this page) 40. 0mm. Next, the outer ring fj and the end face U are performed to remove the can (stage S407), and the steel ring billet is hot-extruded using a special-shaped hole extruder (stage S408). Extrusion conditions in this case: heating temperature is 500 ° C ~ 520 ° C, extrusion speed is 5m / min. However, this condition is appropriately changed depending on the content of boron. Next, after extrusion molding, stretch correction is performed (step S409), and the unsteady portion and the evaluation portion are cut to form a plate-like member 310 (step S410). The plate-like member 3 1 0 is formed by machining a plurality of cut-in portions 3 1 2 (step S41 1). Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Next, the processing of the recess 102 of the cymbal body 101 will be described. Fig. 9 is a schematic perspective view showing the processing device of the recess 102. This processing device 140 is composed of a fixed base 141 penetrating through the main body 101 and fixed in the recess 102, a movable base 142 slid in the axial direction on the fixed base 141, and fixed and fixed on the movable base 142. A saddle 143, a shaft unit 146 composed of a shaft 144 and a driving motor 145 provided on the saddle 143, and a grinding surface 147 provided on the shaft. The shaft unit 146 is provided with a reaction bracket 148 that forms an abutment portion in accordance with the shape of the recess 102. This reaction force bracket 148 is detachable and can slide along the wedge-shaped groove (not shown) in the direction of the arrow in the figure. Further, the reaction force bracket 148 has a holding device 149 for the shaft unit 146, and can be fixed at a predetermined position. In the lower groove of the fixed base 141, a plurality of holding devices 150 are mounted. The holding device 150 is composed of a hydraulic cylinder 151 and a wedge-shaped moving block 152 provided on the shaft of the hydraulic cylinder 151, and a fixed block 153 abutting on the moving block 152 with an inclined surface. Structure, and the side of the oblique line in the figure is attached to the inner surface of the groove of the fixing table 1 4 1. When driving the axis of the hydraulic cylinder 151, the moving block 152 abuts against the fixed block 153, and the moving block 152 is made using a wedge effect. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X29 * 7 mm) ) -27- 529040 A7 B7 V. Description of the invention (25) (Please read the precautions on the back before filling in this page) Move slightly downward (shown by the dotted line in the figure). Therefore, since the lower surface of the moving block 152 is crimped to the inner surface of the recess 102, the fixing table 141 can be fixed in the recess 102. In addition, the cymbal body 101 is mounted on a rotation support table 154 composed of a roller, and is rotatable in a radial direction. In addition, by inserting the spacer 155 tightly between the shaft unit 146 and the saddle 143, the height of the grinding surface 147 on the fixed base 141 can be adjusted. The thickness of the spacer 155 is slightly the same as that of the groove. The saddle 143 is moved in the radial direction of the cymbal body 101 by rotating the handle 156 provided on the movable table 142. The movable table 142 is controlled by a servo motor 157 and a ball screw 158 provided on a fixed table 141. However, since the shape in the recess 102 changes as the processing progresses, it is necessary to appropriately change the shapes of the reaction force bracket 148 and the moving block 152 of the holding device 150. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Figure 10 is a schematic illustration showing the processing method of the recess. First, the fixing device 141 and the reaction force bracket 148 are used to fix the fixing table 141 at a predetermined position in the recess 102. Next, as shown in Fig. (A), the shaft unit 146 is moved along the fixed table 141 at a predetermined cutting speed, and the inside of the recess 102 is cut by the grinding surface 147. After the cutting at this position is completed, the clamping device 15 is removed, and the fixing table 141 is released. Next, as shown in Fig. (B), the cymbal body 101 is rotated 90 degrees on the rotation support table 154, and the fixing table 141 is fixed by the clamping device 150. Then, cutting is performed with the ground surface 147 as described above. After that, the same process was repeated twice more. Next, the shaft unit 146 is rotated 180 degrees, and as shown in Fig. (C), the inside of the recess 102 is sequentially cut. In this case, the same process as described above is performed while the body 101 is rotated 90 degrees. Then, as shown in figure (d), the Chinese national standard (CNS) A4 specification (210X29 * 7 mm) applies to this paper size. -28-529040 A7 B7 V. Description of the invention (26) (Please read the note on the back first) (Fill in this page again) The spacer 155 is tightly inserted into the shaft unit 146 to raise the position of the shaft unit. Further, at this position, the ground surface 147 is sent out in the axial direction, and the inside of the recess 102 is cut. Inserting the cage 130 into the desired shape is almost completed by rotating it 90 degrees while replying. However, cutting of the insertion portion of the temporary tube 308 may be performed in the same manner as shown in FIG. However, the thickness of the spacer for adjusting the height of the shaft unit 146 is the same as that of one side of the temporary tube 308. FIG. 11 is an explanatory diagram showing an assembling procedure of the outer cylinder and the heat transfer sheet. First, as shown in Fig. (A), the belt-shaped member 105a is placed on the work surface, and the heat-conducting sheet 107 is supported standing on both sides thereof. At this time, the both ends of the band-shaped member 105a have a length that is slightly exposed to the outside. The width is used to determine the interval between the welded portion 204 and the welded portion 205 (see FIG. 7). Next, as shown in Fig. (B), the worker W is welded from the outside of the heat conductive sheet 107, and these cells 105c are formed into a C-shaped cross section. This unit 105c is made in advance around the main body 101 and can be arranged at predetermined intervals. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Next, as shown in Figures (c) and (d), the unit 105c is welded to the body 101. The unit 105c abuts its thermally conductive sheet 107 on the protruding portion 201 to perform welding. At this time, the worker W performs hand welding only from the outside of the unit 105c, and does not perform welding from the inside of the unit 105c. Moreover, even if the adjacent unit 105c is welded, since it is welded at a predetermined interval first, a welding gun or electrode rod (T) can be inserted from this gap L to perform welding. In addition, the main body 101 is supported by the rotary support table 208 and the jig 209, so that the main body 105 can be welded while the main body 101 is rotated. Moreover, as shown in Figures (e) and ⑴, the band members 105a and 105a adjacent to the band member 105b are inserted between the band members 105a and 105a, and the section 203 is embedded in the band member. (CNS) A4 specification (210X 297 mm) -29- 529040 A7 _____B7 V. Description of invention (27) (Please read the precautions on the back before filling this page) 10. The segment portion 202 of 5a is further welded by the operator w to the boundary line between the band-shaped member 105a and the band-shaped member 105b (welded portion 204). In this case, welding is not performed from the back side of the connection portion. Furthermore, the outer tube 105 of the shielding container 100 is completed by welding the entire band-shaped member 105b between the adjacent band-shaped members 105a. When assembling the outer tube 105 and the heat conductive sheet 107, following the above-mentioned procedure, welding in the narrow space formed by the outer tube 105 and the heat conductive sheet 107 is not required. That is, in the reference example described above, although the self-propelled welding machine is allowed to run in the space formed in the outer cylinder 503 and the thermally conductive sheet 508, the outer cylinder 105 is assembled by following the above-mentioned procedure. And the thermal conductive sheet 107, all welding can be performed from the outside, even if there is no special welding machine, ordinary welding equipment can be assembled in a shielded container. Therefore, the assembling work of the shield container becomes very easy. The Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs printed back to Figure 1 and Figure 2. The used fuel assembly containing the shielded container 100 contains radiation and disintegrating heat because it contains nuclear fission substances and nuclear fission products. Therefore, it is necessary to reliably maintain the heat removal function, the shielding function, and the criticality prevention function of the shielded container 100 during the storage period (about 60 years). In the shielded container 100 of the first embodiment, the recessed portion 10 of the 胴 body 1 0 1 is machined so that the outer peripheral surface of the cage 1 3 0 can be inserted in a tight state (almost no space), and heat conduction is performed. The sheet 107 is provided between the main body 101 and the outer tube 105. Therefore, the heat from the fuel rod is transmitted to the plutonium body 101 through the cage or the plutonium-filled helium, and is discharged from the outer tube 105 mainly through the heat conductive sheet 107. From the above, the thermal conductivity of the slave cage 130 can be increased, and the heat of collapse heat can be efficiently removed. In addition, the "r-line" generated by the used fuel assembly is determined by the carbon steel paper size to the Chinese National Standard (CNS) A4 specification (210X297 mm) -30- 529040 A7 B7 V. Description of the invention (28) (Please read the notes on the back before filling this page) OR. The stainless steel main body 101, the outer tube 105, and the cover 109 are covered by stainless steel. In addition, the neutral system is shielded by resin 106, so that radiation workers are not affected by radiation pollution. For example: Designed so that the shielding function is: The surface line equivalent ratio is 2 m S v / h or less, and the line equivalent ratio 1 m from the surface is 100 // Sv / h or less. In addition, since the plate-like member 310 constituting the groove is a PC containing boron aluminum alloy, it can prevent the absorption of neutrons and reach a critical value. In the above, according to the shielded container 100 according to the first embodiment, the outer tube 105 has a divided structure and a plurality of units 105c composed of a belt-shaped member 105a and a thermally conductive sheet 107 are produced in plural. The outer side is welded, and the adjacent strip-shaped members 105a are all welded across the strip-shaped member 105b from the outside without welding in a narrow space. Therefore, the welding operation can be easily performed without requiring a special dedicated welding machine. In addition, since the shielding container 100 can be assembled using a widely-used welding device, it can be easily assembled in most companies. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Next, the outer peripheral surface of the cage 130 can be inserted in a close-fit state by machining the recess 102 of the cymbal body 101, so that the thermal conductivity of the cage 130 can be improved. In particular, the heat of collapse is efficiently transmitted to the cymbal body 1 0 through the heat transfer plate 3 1 8 provided on the outer peripheral surface of the cage, and a part of the surface is brought into contact with 剖面 at the angular section 301 b of the cage 1 30. The main body 101 can reliably hold the cage 130 and improve the thermal conductivity. Furthermore, by inserting the temporary tube 308 into the space S, the thermal conductivity is improved. However, in the above-mentioned structure, of course, even if the heat conducting plate 318 is omitted, the heat conductivity can be improved to some extent. In addition, since the space in the recess 102 can be eliminated, the body 101 can be made small and lightweight. However, even in this case, the use of this paper size will not reduce the application of Chinese National Standard (CNS) A4 specifications (210X 297 mm) -31-529040 A7 B7 V. Description of the invention (29) Containment of over-fuel assemblies . Conversely, if the outer diameter of the plutonium body 101 is the same as that of the shield container 500 shown in Fig. 26, the necessary number of grooves can be secured, and the number of used fuel assemblies can be increased. Specifically, in the shield container 100, the number of used fuel assemblies can be up to 37, and the outer diameter of the shield Gu Yi body can be suppressed to 2560mm and the weight to 120 ton. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs [ Modification of Outer Tube and Heat-Conducting Sheet] Figures 12 and 12 are explanatory diagrams showing a modification of the outer tube and the heat-conducting sheet. In this way, the thermal conductive sheet 2 1 0 can also be inclined. The other structures are the same as those of the above-mentioned shielded container. Since the heat transfer sheet 210 is inclined, the resin 106 must be emitted from the neutral member discharge direction of the used fuel assembly, so that the neutral member can be prevented from leaking to the outside through the heat transfer sheet 210. However, in the same figure, although the inclination of the heat conducting sheets 210 cross each other, all the heat conducting sheets may be arranged radially from the center of the container, or may be inclined only in one direction (not shown). Further, as shown in FIG. 13, the belt-shaped member 21 lb may be welded so as to overlap the edge of the belt-shaped member 211 a. In this case, the belt-shaped member 21 la and the heat-conducting sheet 107 are used to make a C-shaped cross-section unit and welded to the 胴 body 101 respectively, and all the belt-shaped members 21 lb are welded between the adjacent belt-shaped members 21 la . Even with this structure, the shield container can be easily assembled in the same manner as described above, and the separate welding portions 212 and 213 can be used to prevent the heat affected portion from being concentrated locally. Further, since the step processing and chamfering of the end edge of the band-shaped member can be omitted, the structure of the outer tube 211 can be simplified. And, in the structure shown in Figure 14, the body of the thermally conductive sheet 214 is folded (please read the precautions on the back before filling out this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 〉 -32- 529040 A7 B7 V. Description of the invention (30) (Please read the precautions on the back before filling out this page) Section C shape and place the belt-shaped member 105a on the heat transfer sheet 214, and The corner edge portion of the thermally conductive sheet 214 is welded to the band-shaped member 105a (welded portion 215). In this way, since the thermally conductive sheet 214 can be placed on the band-shaped member 105a and welded, assembling becomes easy. Moreover, as described above Since welding can be performed from the outside without welding in a narrow space, the shielding container can be easily assembled, and the heat-affected portions can be prevented from being concentrated locally by separating the welding portions 204 and 2 1 5. Furthermore, because copper is made The thermally conductive sheet 2 14 is in contact with the belt-shaped member 105a, so it can efficiently transmit the collapse heat from the inside of the shielded container to the outer tube 105, and it can release heat to the outside. However, the heat radiation route is shown by a lock line in the figure. Second embodiment ] Figure 15 printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics is an explanatory view showing a shielded container according to a second embodiment of the present invention. The shielded container is characterized in that the outer tube 2 1 6 has a mountain shape in section. The heat-conducting sheet 107 is fused to both end edges (welded portion 205) of the belt-shaped member 2 1 6a bent into a mountain shape, unitized, and welded to the protruding portion 201 (welded portion 206). The member 216b is similarly bent and formed, and the segment portion 203 of the band-shaped member 21 6b is fitted into the segment portion 202 of the band-shaped member 216a and welded from the outside (welded portion 204). On the inner side surfaces of the band-shaped members 216a and 216b A honeycomb material is provided. The space of the band-shaped members 216a, 216b and the heat-conducting sheet 107 is filled with resin for neutron absorption. Even with this structure, since all welding operations can be performed from the outside, it is the same as above. The shielding container can be easily assembled, and by separating the welding portions 204 and 205, it is possible to prevent the heat affected portion from being concentrated in the local area. And this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -33- 52904 0 A7 B7 V. Description of the invention (31) (Please read the precautions on the back before filling in this page), because the band-shaped members 216a, 216b are formed in the shape of a mountain, the surface area of the outer tube 21 6 becomes larger, which can improve the heat radiation effect. Furthermore, in a shielded container in which a plurality of plate-shaped heat-radiating sheets protrude from an outer tube, although it is not easy to sweep the corners of the heat-radiating sheet and the outer tube, the mountain-shaped outer tube 2 1 6 has no narrowness. The corners make it easy to sweep the surface of the outer cylinder. However, the valley shape also has the same effect (not shown). In addition, as shown in FIG. 16, the end edge of the band-shaped member 2 1 7 may be placed on the top of the end edge of the thermally conductive sheet 107 and the end edge of the band-shaped member 2 1 7 connected to the adjacent edge. The joint is welded and welded (welded portion 2 1 9). A chamfer is formed at the edge of the band-like member 2 1 7. By forming the outer tube 21 8 into such a mountain shape, the heat radiation performance of the shielded container can be improved.

In addition, the tube 220 is characterized in that the thermally conductive sheet 107 is welded to the center of the belt-shaped member 105a to form a unit 220a having a T-shaped cross section. The welding sequence is slightly the same as that of the first embodiment. First, the heat-conducting sheet 107 is welded to the band-shaped member 105a to form a unit 220a. The heat-conducting sheet 107 and the band-shaped member 105a can be welded from the sheet side, and from both sides to ensure the strength (weld portion 222). Next, the unit 220a is welded to the cymbal body 101 at predetermined intervals. However, the protruding portion 201 is provided on the cymbal body 101, and the heat conductive sheet 107 is welded to the protruding portion 201. The welding is performed from both sides of the thermally conductive sheet 107 in order to ensure the strength. Then, all the band-shaped members 105b are inserted and welded between the adjacent band-shaped members 105a (welded portion 204).

Even so ', since all welding can be performed from the outside without welding in a narrow space, the shielding container can be easily assembled. In addition, since the welding portion 230 and the welding portion 227 are separated from each other, it is possible to prevent the heat-affected portion from being concentrated in the local portion.

At this time, the welding of the ring plate 403 of the unit 402b is performed only from the open sheet side (the welding portion 409). As long as this repetition is performed several times and the rear unit 402 is installed, the outer cylinder 401 can be assembled. However, when it is not easy to insert the ring-shaped resin 408, the ring-shaped resin 408 may be divided in the circumferential direction, and the arc-shaped resin 408x may be stored in the space. However, covers 410 are provided on both sides of the outer tube 401.

Then, the arc plate 456 is completely embedded between the units 452, and the arc plate 453 and the arc plate 456 are welded from the outside. Thus, the assembling of the outer cylinder 451 is completed. However, instead of using a formed resin, it is also possible to charge the resin through a hole provided in the unit 452 (not shown). Even with the above-mentioned structure, since welding in a narrow space is not required and welding can be performed from the outside, welding operations can be easily performed without the need for a special welding machine or the like. Further, since the welded portion 455 and the welded portion 457 are separated, it is possible to prevent the thermal stress from being concentrated locally. However, the above resin 45 8 (45 8c) is divided in the circumferential direction, and the above-mentioned divided resin 45 8c is sequentially placed between the units 45 2a and 45 2b after welding the units 45 2a and 45 2b to cover the arc plate. 456 ground welding is also possible (not shown). [Sixth Embodiment] Fig. 26 is a perspective view showing a shielded container according to a sixth embodiment of the present invention. Fig. 27 is a radial sectional view of the shielded container shown in Fig. 26. The shielding container 1100, the cymbal body 1101, and the bottom plate 1 1 04 of the cymbal body 1101 are forged products made of carbon steel having a T-line shielding function. However, it is also possible to use stainless steel instead of carbon steel. The aforementioned cymbal body 1101 and the bottom plate H04 are joined by welding. In addition, in order to ensure the sealing performance of the pressure-resistant container, a metal gasket is provided between the primary cover 1110 and the main body 1101 (not shown).

Description of Invention (377) (Please read the notes on the back before filling this page) board. The portion of the outer cylinder formed and corresponding to the shield container 1 100 is formed into a mountain shape (mountain portion 1 207). The edge 1 202 of the plate-like member 1201 is welded to the bent edge portion 1 203 (welded portion 1 202a) of the adjacent plate-like member 1201. The plate-like member 1201 has a function of a so-called thermally conductive sheet that releases the collapse heat of the used fuel assembly to the outside. On the one hand, the plate-like member 1 20 1 passes the cord 1204 through the end edge fixing hole 1 205, and rolls the cord 1 204 around the cymbal body 1 101 to fix it. However, the plate-shaped member 1 20 1 can also be printed by processing by the consumer property cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and the space 1 206 formed by the plate-shaped member 1201 and the outer surface of the main body 1101 is provided. Honeycomb material 1210 made of aluminum or copper with good thermal conductivity. The grooves of the honeycomb-shaped member 12-10 are formed in the axial direction of the shield container 1100, and the periphery thereof contacts the inner surface 1211 of the space 1206. This is to improve the thermal conductivity of the slave body 1 101. A part of the honeycomb material 1210 is filled with a resin 1 1 06 having a neutral-shielding function of a polymer material containing a large amount of hydrogen. On the other hand, on the outer peripheral side of the honeycomb material 1210, in order to absorb the thermal expansion of the resin 1106 and the like, a hollow layer 1212 not filled with the resin 1106 is provided. The honeycomb material 1210 and the resin 1106 are filled and compounded in another place, and are inserted and fixed in the space 1206. Further, the resin 1106 in a flowing state may be injected in a state where the honeycomb material 1210 is inserted into the space 1 206 and cured by a thermal hardening reaction or the like. In addition to the honeycomb material 1210, in general, the cross section has a hexagonal shape, and various materials such as a cylindrical material and a corrugated cardboard material can also be appropriately selected.

For example, it is also possible to charge the Raschig ring 1210f of the thermal conductor shown in Fig. 1 into the aforementioned space 1206, and then fill the resin 1106 around the Raschig ring 1210f. Moreover, as shown in Fig. (G), it is also possible to charge the inscribed defogger 1210g to the aforementioned space 1206, and then to charge the resin 1106 to the surrounding space. However, from the point of view of thermal conductivity, the smaller the groove, the better, but it is better to print it with resin 1 106 which is easy to be filled with resin. The outer shape of the honeycomb material 1210 may be a shape other than the above. For example, as shown in (a) of FIG. 30, the outer surface of the plate-like member 1 220 may be valley-shaped (valley-shaped portion 1221). Moreover, as shown in Fig. (B), two mountain-shaped portions 1231 may be provided on the outer surface of the plate-like member 1 230. Further, as shown in Fig. (C), the cross-section of the outer surface of the plate-like member 1 240 may be arc-shaped (arc portion 1 24 1). In addition, as long as the shape of the heat radiation area can be increased, various mountain-shaped portions or valley-shaped portions can be used. 'Furthermore, a valley portion 1 208 formed on the outer surface of the shield container by providing a mountain-shaped portion 1 207 or a valley-shaped portion (in the case of a mountain-shaped portion is a joint portion of a plate-shaped member, and in the case of a valley-shaped portion is a valley portion corresponding thereto) The system is preferably formed with an obtuse angle of 0.

The outer plate-like member 1201 is formed in a mountain shape to expand the heat radiation area, and can efficiently dissipate the collapse heat generated by the used fuel assembly and release it. The collapse heat generated by the used fuel assembly is conducted to the plutonium body 1101 through the cage 1 300 or the plutonium filled with plutonium. Next, the plate-shaped member 1201 and the honeycomb material 1210 having an internal sheet function transmit the collapse heat to the shielding container 1100. In particular, the honeycomb material 1210 is made of aluminum or copper, which has good thermal conductivity, so it can efficiently absorb the heat from the plutonium body 1101 and transfer it to the plate-like member 1201, and release heat from the outside of the shielded container to the outside. . From the above, since the heat of collapse can be efficiently removed, as long as the heat of collapse is the same, the temperature in the shielded container can be kept lower than the conventional example. . However, the r-line produced by the used fuel assembly is made of carbon (please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm)- 44- 529040 A7 B7 V. Description of the invention (42) (Please read the precautions on the back before filling this page) Steel. The main body 1 1 〇 1 made of stainless steel, the plate-shaped member 1 20 1, and the cover 1 1 09 are covered. In addition, the neutral system is shielded by resin 1106, and the radiation-free business workers are not affected by pollution. Specifically, the shielding function is designed as follows: the surface line equivalent ratio is 2 mSv / h or less, and the surface line equivalent ratio from lm is 100 // Sv / h or less. Furthermore, in the cage 1 300, since an aluminum alloy containing boron is used, it is possible to prevent the absorption of the neutrons and to make the used fuel assembly critical. In the above, according to the shielded container 1100 of this embodiment, the plate-shaped member 1201 is mounted on the cymbal body 1101, and the mountain-shaped portion 1 207 is provided in the plate-shaped member 1 201 to form a portion outside the shielded container. Since the honeycomb material 1210 made of aluminum is placed in the space 1206 formed by the plate-like member 1201, the heat conduction efficiency of the burst heat can be improved. Further, according to the shielded container 1100 of this embodiment, since the sheet 1504 does not need to be welded from the outer peripheral surface as is conventionally known, it has the advantage of being easy to manufacture. However, although the used fuel assembly is contained in the above-mentioned shielded container 1100, it is of course possible to contain other radioactive materials. Printed by the Consumer Finance Cooperative of the Smart Finance Bureau of the Ministry of Economic Affairs Figure 31 shows a modification of this embodiment. In this shielding container, a plate-shaped member 1201 made of carbon steel is provided around the concrete body 1101, and a heat-conductive plate 1400 composed of an aluminum plate (or a copper plate or a graphite sheet) is attached to the plate-shaped member 1201. Both sides. In the space formed by the plate-like member 1201, only the resin 1 106 is filled. However, between the outside of the resin 1106 and the plate-like member 1201, an expanded portion 1401 (not shown) is formed. However, the heat-conductive plate 1400 may be provided on only one surface of the plate-shaped member 1201. In addition, in order to improve the heat collection efficiency, as shown in Figure 32, the aforementioned thermally conductive plate can also be extended. The paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) -45- 529040 A7 B7 V. Description of the invention (43) (Please read the notes on the back before filling this page) 14. 00 (extension 1402), and brought into surface contact with the main body 1101. In this case, since the heat can be efficiently transferred from the extension portion 1402 to the heat-conductive plate 1400, the temperature of the resin 1106 can be kept low, and the quality of the resin 1106 can be prevented from being deteriorated. In the above-mentioned structure, the heat transfer by collapse heat is mainly performed by the heat-conductive plate 1400 (in the case of FIG. 32, the extension 1402 including the heat-conductive plate 1400 is included). However, even in the case of using the honeycomb material 1 2 10 described above, the heat-conductive plate 1400 can be attached to the plate-shaped member 1201. This makes it possible to further increase the thermal conductivity of the shielded container. The shape of the heat-conductive plate 1400 is not limited to the shape described above. For example, as shown in Fig. 33, an extension portion 1405 extending to the cymbal body 1 101 may be provided. In this way, the heat collection efficiency from the gadolinium body 1101 can be improved, and the temperature of the resin 1106 and the gadolinium body 1101 can be kept lower. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and as shown in FIG. 34, the intermediate material 1406 may be interposed between the resin 1106 and a part of the plate-shaped member 1201 made of a material such as heat-resistant iron. between. The intermediate material 1406 is a material having good thermal conductivity using an aluminum plate, a copper plate, or the like. Furthermore, it is preferable to use a material that is easily welded to the cymbal body 1101 at the joint portion 1 407 with the cymbal body 1101. For example: carbon steel or stainless steel, which is the same material as the osmium body 1101. The plate-shaped member 1201, the intermediate material 1406, and the joint portion 1407 are welded in advance at another stage before being fused to the concrete body 1101. Welding uses friction stir welding or TIG welding. Fig. 35 is an enlarged view showing a part of Figs. The end of the joint portion 1 4 0 7 forms a chamfer 1407a for welding. Accordingly, since the contact area with the cymbal body 1101 can be enlarged by the welded protruding portion 1407b, thermal conductivity can be improved. This paper size applies to Chinese National Standard (CNS) A4 specification (210X 297 mm) -46- 529040 A7 B7 V. Description of invention (44) (Please read the precautions on the back before filling this page). Fig. 36 shows another modification. The plate-like member 1408 is made of an aluminum material having a function as a heat-conductive material in the same manner as the above-mentioned intermediate material 1406, and a joint portion 1 409 is provided at the end of the plate-like member 1 20 1 to the main body 1 1 0 1. It is preferable that the joint portion 1409 is made of a material that can be easily welded to the main body 1101. In this structure, since the outer tube of the shield container 1 100 is formed of an easy conductor such as an aluminum material, better thermal mobility can be achieved. In the case of an aluminum material, the shield container 1100 can be made lighter. In addition, this structure is suitable for storage containers because of its low heat resistance requirements. The shape of the plate-shaped member 1201 is not limited to the shape shown in FIG. 27. For example, as shown in Fig. 37, a plate-shaped member 1250 having a Y-shaped cross section may be used. The plate-like member 1250 is formed by bending or extrusion. In the case of the plate-like member 1 250, its feet are welded to the cymbal body 1101, and both end edges thereof are joined to the edge 1251 of the adjacent plate-like member 1 250. Thereby, the heat conductive sheet and the outer surface of the shield container 1100 are formed by the plurality of plate-like members 1 250. In this case, the welded portion 1 253 is located at the ridge of the mountain-shaped portion 1 252. However, when the strength of the welded portion 1 253 is low, the welded portion 1 25 3 may be provided in the middle of the mountain-shaped portion 1252 (not shown). It is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. As shown in FIG. 38 (a), a shielded container having a valley portion 1261 may be formed using a plurality of umbrella-shaped plate-like members 1 260. Then, as shown in the same figure (b), the outer surface of the plate-shaped member 1 270 having a T-shaped cross-section is formed into a wave shape (waveform portion 271), and the edge of the plate-shaped member 1 270 is adjacent to the end of the adjacent plate-shaped member 1 270 Margin joint. Even so, the same effects as described above can be obtained. However, these plate-like members 1260, 1 270 can also be formed by sheet metal processing and extrusion processing. This paper size is applicable to China National Standard (CNS) A4 specifications (210X297 mm> -47- 529040 A7 B7. V.
