〔発明の利用分野〕
既設の原子カブリントの定検時における改造工事の際に
廃山される放射性廃棄物の処理に係る処理容器を対象と
した本のである。[Detailed Description of the Invention] [Field of Application of the Invention] This book is directed to processing containers related to the processing of radioactive waste that is discarded during modification work during periodic inspections of existing atomic bombs.
第１図に示す如く、処理容器１にコンクリート２の遮蔽
体を組み込んで処理容器の表面線量率を基準値以下に押
える要領である。As shown in FIG. 1, a shield made of concrete 2 is incorporated into a processing container 1 to suppress the surface dose rate of the processing container below a reference value.
このコンクリート２の遮蔽体の場合、放射性廃棄物３を
収納する実容積が非常に狭くなム処理容器１の数量が増
加する。厚みは５０ｔ〜１５０ｔの範囲が一般的である
又放射性廃棄物を適宜な寸法に切断して処理容器に収納
した場合、運搬時など容器内部での移動、転倒のため非
常に不安定でおる。In the case of this concrete 2 shielding body, the number of processing containers 1 having a very small actual volume for storing radioactive waste 3 increases. The thickness is generally in the range of 50 to 150 tons, and when radioactive waste is cut into appropriate dimensions and stored in a processing container, it is extremely unstable due to movement and overturning inside the container during transportation.
以上のことを根本的に改善することの要望が各方面カラ
提案され、本発明の案出がされたものである。The present invention was devised based on various proposals from various quarters to fundamentally improve the above-mentioned problems.
本発明の目的は前述した如く、放射性廃棄物処理容器の
有効な容積確保、並びに処理容器の表面線量値を基準値
以下になるよう適切、最低限の施策によって得られるこ
と。その他に処理容器が運搬時等に転倒することのない
ように安定性を得、且つ作業能率が向上することを目的
とする。As mentioned above, the purpose of the present invention is to secure an effective volume of a radioactive waste processing container and to bring the surface dose value of the processing container below a standard value by taking appropriate minimum measures. Another purpose is to obtain stability so that the processing container will not fall over during transportation, etc., and to improve work efficiency.
大きな構造物や製品を廃棄物をどのように廃材処理する
か作業が完了してから検討したのでは、作業の手間が二
重になシ、作業完了時期も先に伸びてしまう。このよう
な問題に対し予め処理容器にどのように収納するか決め
てから作業に掛かれば作業中にその処理作業も同時進行
となシ、作業の能率が非常に円滑となる。このような背
景により従来のやり方を根本的に見直しを行ない本発明
を案出するに至ったものである。If we wait until after the work has been completed to consider how to dispose of the waste from large structures and products, we will end up doubling the effort and prolonging the time it takes to complete the work. To deal with such problems, if you decide in advance how to store the materials in the processing container before starting the work, the processing work can be done simultaneously during the work, and the work efficiency will be extremely smooth. Against this background, we have fundamentally reconsidered the conventional method and have come up with the present invention.
第２図は本発明の放射性廃棄物処理容器の全体の構造を
示す。遮蔽体４ａ、４ｂ、４ｃは６ｔの鉄板を使うのが
適箔である。この遮蔽体は４ａのみで１重、４ａ〜４ｂ
で２重構造、４ａ、４ｂ。FIG. 2 shows the overall structure of the radioactive waste treatment container of the present invention. A suitable foil for the shields 4a, 4b, and 4c is a 6t iron plate. This shield is 4a only, 1 layer, 4a to 4b
Double structure, 4a, 4b.

これは廃棄物５の線量率により処理容器の表面線量率を
ある基準値（一般的にｒｉｌｏＯｍ几ｅｍ／ｈ）以下に
押えるために調整機構として作用づせるものである。This acts as an adjustment mechanism to keep the surface dose rate of the processing container below a certain standard value (generally riloOm几em/h) based on the dose rate of the waste material 5.
廃棄物をこの多重構造の遮蔽体４ａ〜４Ｃ内に収納する
場合、配管材とか制御棒駆動機構の廃材などを適宜な寸
法に切断し、固定支持棒６に差【７込んで部内する。従
来は第１図に示す如く廃棄物３を任意に処理容器１に収
納されるため、遮蔽体２と相俟ってその容積効率は非常
に悪い、従って廃棄物を全て収納するためには相当数の
処理容器１を準備しなければならない。しかし本発明は
遮蔽体４ａ〜４Ｃを鉄板多重構造とし且つ廃棄物５を整
然と処理容器１に収納することにより廃棄物５の収納数
量が向上し、結果的には処理容器の数が削減したことを
同じことになる。When storing waste in the multi-layered shields 4a to 4C, piping materials, waste materials from the control rod drive mechanism, etc. are cut into appropriate dimensions and inserted into the fixed support rod 6 to be placed inside. Conventionally, as shown in Fig. 1, the waste 3 is arbitrarily stored in the processing container 1, and together with the shielding body 2, the volumetric efficiency is very poor. A number of processing containers 1 must be prepared. However, in the present invention, the shielding bodies 4a to 4C have a multi-layer iron plate structure and the waste 5 is stored in the processing container 1 in an orderly manner, thereby increasing the amount of waste 5 stored, and as a result, reducing the number of processing containers. will be the same.
第２図における固定支持棒６は処理容器１の低板に溶接
等によシ第３図に示す如く固定するが第４図に示す如く
遮蔽体４ａ〜４Ｃに底板８を設けてその底板８に固定す
る方法のいずれでもよい。The fixed support rod 6 in FIG. 2 is fixed to the lower plate of the processing container 1 by welding or the like as shown in FIG. 3, but as shown in FIG. Any method of fixing it may be used.
この固定支持＄６の員数は予めこの処理容器１にどのよ
うな廃棄物を収納するかにょシビッチを設定し固定支持
棒６の取付は数を決めることができる。The number of fixed supports 6 can be determined in advance based on what kind of waste is to be stored in the processing container 1, and the number of fixed support rods 6 to be attached can be determined in advance.
又廃棄物５が第３図に示Ｔ如く種々異なる場合でもその
収納はきちんとできる。この場合でも予め収納する廃棄
物の形状によシ固定支持棒６のピッチは予め設定可能で
ある。Furthermore, even if the waste 5 is of various types as shown in FIG. 3, it can be properly stored. Even in this case, the pitch of the fixing support rods 6 can be set in advance depending on the shape of the waste to be stored.
尚既に公知例の処理容器（第６図、第７図）のように筐
用する場合も可能であるが本発明の主旨は、第２図、第
５図のような廃棄物の処理を目的としてお乞従ってこれ
らの詳細の記述は削除する。Although it is possible to use a case like the already known processing containers (Figs. 6 and 7), the gist of the present invention is to treat wastes as shown in Figs. 2 and 5. As a result, these detailed descriptions will be deleted.
第２図において遮蔽体４ａ、４ｔ）、４Ｃは一般に６ｔ
を使うのが製作上、成形上適当と考えるが厚板の鉄板等
を使い遮蔽体を１重で実施することも可能であるがその
ときは予め遮蔽体の線量率が分っていて処理容器１の表
面線量率が基準値以下になるようにできることが肝要で
ある。In Fig. 2, the shields 4a, 4t) and 4C are generally 6t.
I think it is appropriate to use a shielding material in terms of production and molding, but it is also possible to use a single layer of shielding material using a thick iron plate, etc., but in that case, the dose rate of the shielding material is known in advance and the treatment container It is important to be able to keep the surface dose rate of 1 below the standard value.
イ 遮蔽体を多重方式にすることにより適切に処理容器
１の表面線量率をコントロールでき廃棄物５の収納容積
を大きく確保できる。(b) By using a multiple shielding system, the surface dose rate of the processing container 1 can be appropriately controlled, and a large storage capacity for the waste 5 can be secured.
口 処理容器１の運搬時に廃棄物５の安定性が良いため
に運搬時の安全が得られる。Since the waste 5 has good stability during transportation of the treatment container 1, safety during transportation can be achieved.
ハ 廃棄物５が規則的に配置されるため局部的に線量率
が偏在することがなくなる。C. Because the waste 5 is arranged regularly, the dose rate is not locally unevenly distributed.
二 処理容器１の収納が明確なために廃材収理作業の能
率が向上する。2. The efficiency of waste material collection work is improved because the storage of the processing container 1 is clear.
ホ 固定支持棒６も遮蔽効果に寄与する。E. The fixed support rod 6 also contributes to the shielding effect.
へ 廃棄物５の形状が６１．６２．６３のように種々異
なったものでも収納は可能である。Even if the waste 5 has a variety of shapes such as 61, 62, and 63, it is possible to store it.
この場合予め固定支持棒のピッチが設定できればその収
納効率は改善可能である。In this case, if the pitch of the fixed support rods can be set in advance, the storage efficiency can be improved.
