Planning of the plutonium utilization in a thermal reactor have been investigated to evaluate the scenario for FBR development. Plans for the partial loading of MOX fuel in the Takaham-3,4 plant are studied. Information of the full MOX utilizing plans in an advanced light water reactor is summarized based on the documents distributed at the related technical committee. Nuclear compositions of the spent MOX fuel have been evaluated using SRAC and ORIGEN-2 code. Results of the study are as follows: (1)Surveying the status of MOX fuel utilization. Based on the public documents, the status and plans for utilizing both the partial loading and the full loading of MOX fuel in the LWR core have been summarized. (2)Evaluation of spent MOX fuel compositions. Nuclear compositions of the spent MOX fuel have been evaluated and summarized for both the APWR uranium core and APWR plutonium core.
