Post irradiation examinations and computational analysis of high burnup UOX and MOX spent fuels for interim dry storage
Post irradiation examinations (PIE) were carried out for a high burn-up UOX spent fuel pin (average burn-up 60GWd/t) and 2 MOX spent fuel segments (average burn-up 45GWd/t). The validity of the ORIGEN-2 and VIM-BURN code were assessed through PIE results. In the results using ORIGEN-2, calculation values for the isotopic composition of U and Pu agreed with experimental data within 13% except for Pu-238. In the results for fission products, the calculation values for Nd-143, Nd-145 and Eu-153 which have a large neutron absorption cross section agreed within 10%. From the results of VIM-BURN calculation for pellet, the concentration profile of U and Pu agreed within experimental uncertainties. It was concluded that the ORIGEN-2 and VIM-BURN codes could be applied to evaluation of high burn-up UOX fuel and MOX fuel for spent fuel storage.
