摘要： A method of fabricating metallic fuel from surplus plutonium may include combining (102) plutonium oxide powder and uranium oxide powder to obtain a mixed powder with reduced proliferation potential. The mixed powder may be electroreduced (104) in a bath of molten salt so as to convert the mixed powder to a first alloy. The first alloy may be pressed (110) to remove a majority of the molten salt adhered to the first alloy to form a pressed alloy-salt mixture. The first alloy may be isolated (112) from the salt by melting the pressed alloy-salt mixture. The first alloy may be further processed to fabricate a fuel rod. Accordingly, the metallic fuel produced may be used in a fast reactor system, such as a Power Reactor Innovative Small Module (PRISM).

摘要： Nuclear fuel dissolution apparatus comprises a perforated sloping ramp (6) located within a process chamber (1). A pulsation member creates pulses in the solvent in the container, and the perforations of the sloping ramp are designed to direct pulses of solvent along and up the ramp. A discharge point (17, 18) for fuel holes is disposed at an upper region of the ramp. A method of dissolving fuel in chopped nuclear fuel pins is also described.

摘要： The invention relates to a process for the synthesis of a mixed peroxide or hydroxo-peroxide of an actinyl and of at least one cation X
1 , in which the actinyl is a uranyl or a neptunyl and said at least one cation X
1 is a doubly, triply or quadruply charged cation of a metal. This process comprises the reaction, in a solvent, of a salt of said at least one cation X
1 with a compound C
2 chosen from the mixed peroxides and hydroxo-peroxides of the actinyl and of at least one singly charged cation X
2 , as a result of which the compound C
2 is converted into the peroxide or the hydroxo-peroxide by replacement of said at least one cation X
2 with said at least one cation X
1 . It also relates to a process for the synthesis of a mixed oxide of an actinide chosen from uranium and neptunium, and of at least one metal capable of forming a doubly, triply or quadruply charged cation, which implements the preceding synthesis process. It also relates to a mixed peroxide or hydroxo-peroxide of an actinyl and of at least one doubly, triply or quadruply charged cation of a metal, and also to the use thereof for preparing a mixed oxide of an actinide and of at least this metal. Uses: manufacture of mixed oxides of actinides suitable for use in the manufacture of nuclear fuel pellets or of transmutation targets, decontamination of effluents contaminated with radionuclides from nuclear facilities, etc.
