Preliminary analysis on characteristics of the wastes from the pyo-processing of SFR SNFs based on the material balance of SFR FSv5.1

SFR burners are necessary to transmute long-lived actinides and fission products and inevitable SNFs generation is accompanied. Thus, characteristics of SFR SNFs and wastes from the pyro-processing of SFR SNFs must be identified for accurate fuel cycle analyses. In this study, preliminary analysis on characteristics of wastes from the pyro-processing of SFR SNFs based on the material balance of SFR FS v5.1 is conducted. Characteristics of wastes and products from the pyro-processing of SFR SNFs based on material balance of SFR FSv5.1 are evaluated in this study. The large reduction in heat load of repository at the disposal time can be achieved by complete reuse of the U/TRU ingot because most of the decay heat, radioactivity, and radiotoxicity are generated from the U/TRU ingot.
