FBRサイクル実用化戦略調査研究の一環として酸化物電解法に関し、現状の知見に基づき、経済性向上を目指した合理化プロセスを構築し、さらに機器設計、セル内機器配置設計等のシステム設計を実施し、経済性について検討した。その結果、合理化による設備削減や建屋縮小で資本費の低減が見込まれた。今後の施設設計において、操業費も含めた総合評価でも、経済性の向上が見込まれることが分かった。

The oxide electrowinning method is one of the non-aqueous reprocessing methods, and the construction of a compact, economical plant is expected in the combination with this reprocessing method and the fuel fabrication method utilizing the vibro-compaction process. For this reprocessing method, the rational process flow has been constructed on the basis of the existing technical information, from the viewpoint of the improvement of the economical efficiency. The conceptual design study of the main equipment concept and the equipment layout in main process cells on the basis of this process flow has been carried out from the viewpoint of the safety and operability. Then the number of equipments in this system and floor space of the process cells concerned with the economical efficiency have also been evaluated. In result, it has been seen that the capital cost by the future plant conceptual design study would be improved compared with the previous design, accordingly with the diminution
