The core nuclear analysis method by the direct response matrix method, which can analyze the effects of intra and inter assembly heterogeneities precisely, has been developed. In this research, the new nuclear analysis method based on current coupling neutron response reconstruction (CCNR) method, which can achieve speed up by the same analysis accuracy as the direct response matrix method, has been developed.
