In order to analyze the reactivity effect of Pu heterogeneous distribution in MOX fuel on the criticality analysis of light water reactor MOX core physics experiments, a parametric study has been performed based on the experimental specifications of KRITZ-2: 19 and so on to understand the characteristics of the effect, and the effect on the reactivity analysis of the MOX core physics experiments tested at the EOLE critical facility has been calculated with MVP.
