✦ Synopsis
Inventories of secondary nuclear materials such as plutonium (Pu), minor actinides (MAs) and reprocessed uranium (RepU), generated in spent fuel in the wake of nuclear electricity production were predicted for the world and Japanese cases by IAEA-VISTA code, which can be applied to the evaluation of the nuclear fuel cycle with thermal power reactors. Three strategic input parameters, i.e., nuclear capacity growth, reprocessing ratio and MOX fuel use ratio, were incorporated in the code as well as other technical parameters with respect to reactor-type share, burnup of individual reactor type, load factor, enrichment, etc. The secondary nuclear material inventories in spent fuel discharged from PWR and BWR were calculated for the nuclear fuel cycle in the world and in Japan. VISTA calculation clarified anticipated quantities of Pu in spent fuel and separated form, quantities of MAs (Np, Am, and Cm) and RepU until 2050. MA data resulted from the VISTA calculation were applied to evaluate the mass balance of Np and MAs in the nuclear fuel cycle for Protected Plutonium Production (PPP: P 3 ) with the 1 GWe class PWR, and possible numbers of PWR with available quantities of Np and MAs in the world and in Japan were appraised.
