Title:
プルトニウム（ＩＶ）を還元することなくウラン（ＶＩ）とプルトニウム（ＩＶ）を分離するためのカルバミド
Document Type and Number:
Japanese Patent JP7222935
Kind Code:
B2
Abstract:
The use of carbamides as extractants for fully or partially separating uranium(VI) from plutonium(IV) in an aqueous solution obtained by dissolving a spent nuclear fuel in nitric acid, by method of liquid-liquid extraction, without carrying out any reduction of the plutonium(IV) to plutonium(III). The invention also relates to new carbamides. Uses are the processing of spent nuclear fuels based on uranium (especially uranium oxides—UOX) or uranium and plutonium (especially mixed uranium and plutonium oxides—MOX).
