本発明は放射性洗濯廃液、特に非イオン系液体洗剤を使
用した放射性洗濯廃液の固化処理方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for solidifying radioactive laundry waste, particularly using a non-ionic liquid detergent.
従来より、原子力施設より排出される衣類等の洗濯廃液
は放射濃濃度が極めて低いためこのまま海に放出されて
きた。Conventionally, laundry waste fluid from nuclear facilities, such as clothing, has been discharged directly into the ocean because its radioconcentration is extremely low.
しかしながら、近い将来環境保全の観点から海に放出す
ることが困難になることが予想されるので、他の放射性
廃液と同様に個化処理の検討が現在行われつつある。However, it is predicted that it will be difficult to release it into the sea in the near future from the perspective of environmental conservation, so studies are currently being carried out on individual treatment like other radioactive waste liquids.
現在、放射性廃液の固化処理方法として使用されている
方法は、セメント固化法やアルファルト固化法であるが
、最近プラスチック個化法がその優れた放射能閑じ込め
能力や減容性の大きいことから注目されている。Currently, the methods used to solidify radioactive waste liquid are the cement solidification method and the alfalut solidification method, but recently the plastic singulation method has been shown to have an excellent ability to contain radioactivity and a large capacity to reduce volume. It is attracting attention from

非イオン系液体洗剤を使用した放射性洗濯廃液では乾燥
処理工程時に放射性洗濯廃液が粉体化せず液状のままで
あり、この液状の放射性洗濯廃液がプラスチック固化剤
と混合しても分離して固化することが困難であった。In other words, two types of detergents are generally used for clothing, etc.: ionic ABS (sodium alkylbenzene sulfonate) powder detergents and nonionic liquid detergents. However, in the case of radioactive laundry waste water using the latter non-ionic liquid detergent, the radioactive laundry waste fluid does not turn into powder during the drying process and remains in liquid form. Even when waste liquid is mixed with a plastic solidifying agent, it is difficult to separate and solidify it.

リル酸メチルモノマーを主成分とするプラスチック固化
剤で放射性洗濯廃液を固化することを特徴とする。[Summary of the Invention] That is, the method of the invention is characterized in that radioactive laundry waste liquid is solidified with a plastic solidifying agent whose main components are an unsaturated polyester resin and a methyl methacrylate monomer.

和ポリエステル樹脂に対して３０重量％が適している。Examples of the plastic solidifying agent used in the present invention include one obtained by adding a methyl methacrylate monomer to an unsaturated polyester resin obtained by condensing maleic anhydride and phthalic anhydride with propylene glycol. A suitable mixing ratio of methyl methacrylate monomer is 30% by weight based on the unsaturated polyester resin.
本発明においてはさらに上述の成分の他に常用されるス
チレンモノマーを添加することができる。In the present invention, commonly used styrene monomers can be added in addition to the above-mentioned components.

りプラスチック固化体が得られる。In the present invention, for example, radioactive laundry waste liquid containing nonionic liquid detergent is added to a plastic solidifying agent as it is without drying, and then catalysts such as a polymerization initiator and a polymerization accelerator are added and mixed at room temperature. By leaving it to stand, a solidified plastic product is obtained.

When we added and mixed Suncobalt and observed the condition after leaving it for a day and night, we found that it had solidified and the compressive strength was 350k.
A solidified plastic material of g/cm3 was obtained.

Dissolve and mix evenly,
When a catalyst is added, the unsaturated polyester resin copolymerizes with the methyl methacrylate monomer, resulting in a strong plastic solidification.
