It has been investigated the super FR MA transmutation core in which MOX and blanket fuels have layered structure to utilize the characteristic axial spectrum change for MA transmutation. Although MA transmutation improved as the increase of MA loading amount, the condition of negative void reactivity imposed a limitation to the MA transmutation performance.
