NUCLEAR FUEL PELLET DESIGN TO MINIMIZE DIMENSIANAL CHANGES

摘要

An improved nuclear fuel composition is characterized by a mixture of the dioxide of uranium and plutonium with pores of a specified size and volumes of each size. The volume of pores in size is adjusted so that each group of pores is removed by the nuclear fission induced process of densipication and the volume removed is balanced by the volume added by the nuclear fission induced process of solid state swelling.
