Abstract

Th-Pu mixed oxide fuel in combination with SiC cladding appears to be one of the few practical methods that would allow extending the burnup from current limit of 50 MWd/kg to 100 MWd/kg or beyond. With initial Pu loading of 19%, a batch average burnup on the order of 126 MWd/kg can be achieved, which is greater by a factor of 2.5 than is feasible with Zircaloy clad UO<sub>2</sub> fuel with 5% enrichment. This leads to a major reduction in spent fuel produced per kWh. To achieve such burnup at the standard power density requires three 32.7 months cycles (8.2Y total), which is well beyond the reach of Zircaloy clad fuel.
