Keywords:Low enriched uranium, Reactivity change, Center core, KUCA

Plan for utilization of low enriched fuel at KUCA has been in progress. In safety analysis of reactivity insertion during reactor start up procedure, reactivity and reactor power change analysis by raising the center core of KUCA solid moderated core is important issue. We will present the results of this analysis.
