Abstract:
A method of producing a UO.sub.2 -based fuel pellet from an irradiated UO.sub.2 -based fuel pellet, the method comprising:heating an irradiated UO.sub.2 -based fuel pellet in an oxidizing gas, to produce a U.sub.3 O.sub.8 -based product,mixing the U.sub.3 O.sub.8 -based product with an additive comprising at least one oxide of an element selected from the group consisting of Nb, Ti, V, Al, Mg, Cr, Si and Li, to produce a mixture,pressing the mixture into a green pellet, andsintering the green pellet in a reducing gas atmosphere to reduce the U.sub.3 O.sub.8 -based product to a UO.sub.2 -based product.
