Today, global thorium reserves are around four times that of uranium reserves, and ThO2 is cheaper than UO2. The next generation of reactor shows fast reactor types using (U-Pu)O2. It contains combinations of ceramic fuels based on UO2, PuO2, and ThO2. Using a new version of the FRAPCON code, get the ability to predict thorium fuels. The FRAPCON fuel codes permit the addition of capacity to simulate thorium fuel and compare fuel performance with standard UO2. The proposed strategy uses ThO2 75 wt% composed of UO2 25 wt% with enrichment equal to 19.5 wt%. In comparison, the second strategy uses a balanced composition of ThO2 at 93 wt.% combined with PuO2 at 7.0 wt.%.openAccessTexto completo de eventohttps://orcid.org/0000-0002-2181-8704
