Comparative Study of UO2 and (Th,U-233)O2 Performance in Small Long-Life PWR Fuel Cell

A study was performed comparing the performance of UO2 and (Th,U-233)O2 fuel in small long-life PWR. The neutronic calculation carried out by PIJ module SRAC2006 done to a cell 10 years operation. conducted varying enrichment U-235 U-233 for 1% - 20% also volume fraction 40%, 45%, 50%, 55%, 60%. observed needed each type gain criticality years, infinite multiplication factor (k-inf) value, conversion ratio (CR) value. results showed that 60% gave critical conditions with lowest highest both types. While terms fissile nuclide needed, had better than UO2, because only 5% while 9%
