The resource-renewable boiling water reactor (RBWR) is a new reactor concept and one option for mitigation against the negative environmental impact of transuranium elements (TRUs) of spent fuels. Not only a hexagonal tight fuel lattice but also boiling coolant water promote hardening of neutron energy spectrum and burning of TRU in RBWR. In this presentation, RBWR back-fit core which adopts the concept of RBWR as current BWR will be reported.
