FIELD: the invention refers to the field of atomic energy and is used at producing ceramic nuclear fuel for heat-generating elements of nuclear reactors.
SUBSTANCE: mode of receiving fuel pellets for heat-generating elements out of uranium dioxide, including preparation of pressed powder out of uranium dioxide of ceramic variety, pressing and agglomeration of pellets. The pressed powder is received by way of decomposition of ill-conditioned sintered pellets in a mill with grinding bodies and adding 2-4 mass.% cellulating substance, and also out of uranium dioxide received according ADU-process, and out of uranium dioxide received by way of decomposition of ill-conditioned sintered pellets in a mill with grinding bodies and with adding 2-4 mass.% of cellulating substance.
EFFECT: allows to increase quality of cake nuclear fuel with simultaneous processing of spoilage in the form of ill-conditioned sintered pellets.
