金属電解法乾式再処理の実工程を模したプロセス試験を行うため、主要工程,電解還元工程と電解精製工程をシーケンシャルに連続した試験をウラン及びプルトニウムを、実機の1/1000規模の試験装置を用いて行った。その結果、運転パラメータの変動,製品成分,アクチナイドの系内分布などの基礎データを取得した。

To demonstrate the real process of metal pyro-reprocessing of nuclear spent fuels, sequential tests of major step were performed, such as electro-chemical reduction of MOX pellets and electro-chemical recovery of U metal and U-Pu alloy, in 1/1000 scale w.r.t. the real process. Variation in various operation parameters, product composition, and actinide distribution were investigated in the sequential tests.
