湿式再処理プロセスにおける完全焼却処分が可能な抽出剤の一つとして、モノアミド化合物が提案されている。U及びPuの濃度分布計算を分配比の酸濃度及び元素濃度依存性を考慮して行い、N,N-di-(2-ethyl)hexylbutanamideを用いた再処理プロセスの成立性を検討した。

Monoamide compounds are porposed as complete incinereable extractants for aqueous reprocessing of nuclear spent fuel. The performance of the reprocessing processes where N,N-di-(2-ethyl)hexyl-butanamide is used as extractant is evaluated based on concentration profiles of U and Pu calculated with the consideration of acid and element concentration effects on the distribution ratios of U and Pu.
