A Monte Carlo code system has been developed to design an innovative water-cooled reactor, Resource-renewable Boiling Water Reactor (RBWR), which enables to burn transuranium elements (TRUs) efficiently. The system can perform multiphysics calculations of whole-core Monte Carlo neutronics, thermal-hydraulics and burnup; thus uncertainty induced by group-constant generation can be excluded. It has been confirmed that the pseudo material construct method can reduce memory requirement significantly and thus the reactor core design with whole core Monte Carlo calculations can be performed even with current computational resource.
