Possibility for realization of the "Equilibrium Core"concept,in which the self-generated MAs and LLFPs are confined,with either isotope or element separation for LLFPs is evaluated with respect to the nuclear properties for MOX,nitride and metallic fuels.From the viewpoint of the risk of geological disposal,it is possible to incinerate with element separation for Tc,I and Se even in the MOX fueled core.From the standpoint of the limit of confinable amounts ofLLFPs,on the other hand,Tc,I ,Se,Sn and Cs can be incinerated with the element separation in case that the nitride fuel is chosen.
