Description
本發明係有關於一種污染擦拭取樣裝置，尤指一種密封鋼筒表面輻射污染擦拭取樣裝置。The invention relates to a pollution wiping sampling device, in particular to a radiation pollution wiping sampling device for sealing a steel cylinder surface.
用過核子燃料以貯存之方式處理，以貯存而言分為兩種方式，一為濕式貯存，另一則為乾式貯存。濕式貯存乃是將用過燃料貯放於反應器廠房之燃料(水)池中。乾式貯存顧名思義即採非以水為屏蔽或貯存環境的方式。惟因燃料池很難再加以擴充，致貯存容量有所限制，故當燃料池即將貯滿時，需將用過核子燃料移出由濕式貯存轉為乾式貯存，以有效抒解核能電廠燃料池貯存問題與免於暫時停止運轉之困境。當溼式貯存轉成乾式貯存時，必須小心運送用過核子燃料，以防止嚴重的輻射污染。當溼式貯存轉成乾式貯存時，其運作方式為將用過核子燃料置於鋼筒內，加以密封抽真空後，灌入惰性氣體維持其穩定性後，其外再以金屬或混凝土護箱包覆作為屏蔽。在運貯操作程序中，密封鋼筒置入金屬或混凝土護箱後須檢測其表面輻射污染程度，因密封鋼筒與護箱間隙僅約2公分，且長度約5公尺(人員無法觸及與進行表面輻射污染擦式取樣)，故目前尚未有精確且有效的偵測裝置，因此測量出來的數據並不具代表性與準確性。為了改善上述問題，本發明提供一種用於偵測(裝載於金屬或混凝土護箱內的)密封鋼筒表面輻射污染擦拭取樣裝置。The use of nuclear fuels for storage is divided into two ways in terms of storage, one for wet storage and the other for dry storage. Wet storage is the storage of used fuel in a fuel (water) tank of a reactor building. Dry storage, as its name implies, is not a way to shield or store water. However, because the fuel pool is difficult to expand, the storage capacity is limited. Therefore, when the fuel pool is about to be full, the used nuclear fuel should be removed from the wet storage to the dry storage to effectively relieve the nuclear power plant fuel pool. Storage problems and freedom from temporary suspension. When wet storage is converted to dry storage, the spent nuclear fuel must be carefully transported to prevent serious radiation contamination. When wet storage is converted to dry storage, it is operated by placing the used nuclear fuel in a steel cylinder, sealing it and vacuuming it, and then filling it with inert gas to maintain its stability, and then it is covered with metal or concrete. Overlay as a shield. In the operation and storage operation procedure, the sealed steel cylinder must be tested for the degree of surface radiation pollution after being placed in a metal or concrete protective box, because the gap between the sealed steel cylinder and the protective box is only about 2 cm, and the length is about 5 meters (the personnel cannot touch and For surface radiation contamination sampling, there is no accurate and effective detection device, so the measured data is not representative and accurate. In order to improve the above problems, the present invention provides a radiation contamination wiping sampling device for detecting a surface of a sealed steel cylinder (loaded in a metal or concrete cage).

Representative.
為達到上述之目的，本發明係為一種污染偵測裝置係對密封鋼筒進行取樣，得到至少一樣品，並依據該樣品得知密封鋼筒外表面每單位面積的輻射污染程度。該污染偵測裝置主要包含一取樣棒及一管體，該取樣棒設於該管體，該取樣棒從密封鋼筒表面固定之面積取樣，並於取樣期間對取樣面積施加固定之壓力。In order to achieve the above object, the present invention is a pollution detecting device that samples a sealed steel cylinder to obtain at least one sample, and according to the sample, the degree of radiation pollution per unit area of the outer surface of the sealed steel cylinder is known. The pollution detecting device mainly comprises a sampling rod and a tube body. The sampling rod is disposed on the tube body. The sampling rod is sampled from a fixed area of the surface of the sealing steel cylinder, and a fixed pressure is applied to the sampling area during sampling.

As shown in the above embodiment, the embodiment is different from the above embodiment in that, in order to facilitate the contamination detection device 1 to be fixed between the sealing steel cylinder and the protection box, the tube body 12 is provided with a fixing ring 123. The tubular body 12 is fixed to the sealed steel cylinder and the protective box through the fixing ring 123.
請參閱第五圖，係本發明之另一較佳實施例之結構示意圖。如圖所示，承上述實施例，本實施例與上述實施例不同在於，為了方便該取樣棒10之該U型取樣部103收至該管體12內，該管體12靠近該U型取樣部103之一端之開口半徑大於其另一端之開口半徑，而該管體12靠近該U型取樣部103之一端之開口係呈漸縮狀。Please refer to the fifth figure, which is a schematic structural view of another preferred embodiment of the present invention. As shown in the above embodiment, the present embodiment differs from the above embodiment in that, in order to facilitate the receiving of the U-shaped sampling portion 103 of the sampling rod 10 into the tubular body 12, the tubular body 12 is adjacent to the U-shaped sampling. The opening radius of one end of the portion 103 is larger than the opening radius of the other end, and the opening of the tube body 12 near one end of the U-shaped sampling portion 103 is tapered.
請參閱第六圖，係本發明之另一較佳實施例之結構示意圖。如圖所示，承上述實施例，本實施例與上述實施例不同在於，為了方便拉回該取樣棒10，該取樣棒10遠離該U型取樣部103之一端設有一繩體109，當拉回該繩體109時，該取樣棒10會被拉回至該管體12內。Please refer to the sixth drawing, which is a schematic structural view of another preferred embodiment of the present invention. As shown in the above embodiment, the embodiment is different from the above embodiment in that, in order to facilitate the pulling back of the sampling rod 10, the sampling rod 10 is provided with a rope body 109 away from one end of the U-shaped sampling portion 103. Upon returning to the cord 109, the sampling rod 10 is pulled back into the tubular body 12.
請參閱第七圖，係本發明之另一較佳實施例之結構示意圖。如圖所示，承上述實施例，本實施例與上述實施例不同在於，為了讓該取樣試紙1035更緊貼密封鋼筒之表面，該取樣棒10之該U型取樣部103之該第一取樣支架1031及該第二取樣支架1033之間設有一彈簧108，利用該彈簧108之彈力將該第一取樣支架1031及該第二取樣支架1033撐開。Please refer to the seventh figure, which is a schematic structural view of another preferred embodiment of the present invention. As shown in the figure, in the above embodiment, the present embodiment is different from the above embodiment in that, in order to make the sampling test paper 1035 more closely adhere to the surface of the sealing steel cylinder, the first portion of the U-shaped sampling portion 103 of the sampling rod 10 A spring 108 is disposed between the sampling bracket 1031 and the second sampling bracket 1033, and the first sampling bracket 1031 and the second sampling bracket 1033 are opened by the elastic force of the spring 108.
請參閱第八圖，係本發明之另一較佳實施例之結構示意圖。如圖所示，承上述實施例，該管體12皆為單一的，本實施例與上述實施例不同在於，為了增加該管體12之長度，該管體12可在連接至少一管體12，如此不但增加該管體12之長度，因該些管體12為組裝式，容易拆卸及容易收納。而該些管體12間係以一接頭14連接，如此可快速連接各管體12。Please refer to the eighth drawing, which is a schematic structural view of another preferred embodiment of the present invention. As shown in the above embodiment, the tube body 12 is single, and the embodiment is different from the above embodiment in that, in order to increase the length of the tube body 12, the tube body 12 can be connected to at least one tube body 12. This not only increases the length of the tubular body 12, but the tubular bodies 12 are assembled, easy to disassemble and easy to store. The tubes 12 are connected by a joint 14, so that the tubes 12 can be quickly connected.
請參閱第九圖，係本發明之另一較佳實施例之結構示意圖。如圖所示，承第八圖之實施例，該管體12之長度變長，本實施例與上述實施例不同在於，因增加該管體12之長度，若利用該繩體109收回該取樣棒10，因該繩體109隨該管體之長度增加，該繩體109的長度亦增加，如此造成該取樣棒10容易搖晃不易回收，所以該取樣棒10之該握把101可連接至少一棒體16，以該棒體16取代該繩體109，改善該取樣棒10容易搖晃不易回收之問題。Please refer to the ninth drawing, which is a schematic structural view of another preferred embodiment of the present invention. As shown in the figure, in the embodiment of the eighth embodiment, the length of the tubular body 12 becomes longer. This embodiment differs from the above embodiment in that the length of the tubular body 12 is increased, and the sampling is retracted by the cord body 109. The rod 10, because the length of the rope body 109 increases with the length of the tube body, the length of the rope body 109 also increases, so that the sampling rod 10 is easily shaken and difficult to recover, so the grip 101 of the sampling rod 10 can be connected to at least one. The rod body 16 replaces the rope body 109 with the rod body 16, which improves the problem that the sampling rod 10 is easily shaken and is difficult to recover.
