POROUS UO2 SINTERED PELLET FOR ELECTROREDUCTION PROCESS, AND PREPARATION METHOD THEREOF

摘要

Porous UO2 sintered pellets to be fed into an electrolytic reduction process for the purpose of metallic nuclear fuel recovery, include one or more hollow spaces formed from the surfaces toward the interiors thereof. When the porous UO2 sintered pellets are used in the electrolytic reduction process, the efficiency increases.
