新型転換炉ふげん発電所における放射性廃棄物処理設備では、廃樹脂減容安定化処理装置及び洗濯廃液濾過装置の導入を計画している。廃樹脂減容安定化処理装置については、実廃樹脂を使い、減容・減重性能、無機化性能、無害化性能、核種の保持・移行性能等に係る確認試験を実施し、実用化へ向け十分な性能が得られることを実証した。また、洗濯廃液濾過装置に関しては、現在2つの方式を比較検討しているが、ホット試験において、放射能やCODの除去性能に関して実機への適用が可能であることを確認した。

Advanced Thermal Reactor Fugen Nuclear Power Station is planning to introduce 'spent resin volume reduction and stabilization processing device' and 'laundry drain filtering device' in radioactive waster treatment system. As for the former device, we demonstrated sufficient performance of this device by carrying out the confirmation test using real spent resin relating to the following points: performance of volume and weight reduction; change to inorganic material; detoxification; and retention and transfer of nuclide, etc. As for the latter device, we are studying two methods now. However, we confirmed that it is possible to apply the removal performance of radioactivity and Chemical Oxygen Demand to real machine by carrying out hot test.
