The particular characteristics of an effective delayed neutron fraction are found in a heterogeneous fuel solution system the present study. Those against conventional systematic understanding successfully employed homogeneous system. Therefore, systems should be validated by new understanding. For understanding, is described geometrical buckling based on Fermi age theory relation between and concentration To establish numerically evaluated with its distribution As result, it that becomes small while large, as increase level decreases. It concluded change leakage effect due to for horizontal direction causes above, have been varies depending heterogeneity. This result will contribute critical safety systems.
