A fast reactor with high MA transmutation capability is indispensable to reduce high-level waste in nuclear power generation including the current LWR. In this presentation, we report a core concept in which Cm is attenuated by temporary storage of MA and MA with Am as the main nuclide is loaded in the blanket at high concentration. In this core concept, it is possible to improve the MA transmutation capability within the aggregate heat generation limit and within the range of less influence on the void reactivity.
