Comparison of CPM-3 Thorium Pin Cell Benchmark with Other Computer Codes

摘要

We modified the CPM-3 cross section library to represent the Th depletion chain and performed Th pin cell depletion calculations. The CPM-3 burnup-dependent k_∞ values compare reasonably well with those reported previously by Zhao, et al., although we observe more substantial differences in actinide number densities. We expect improvements in the CPM-3 results through a refinement of the Th transmutation chain. The results of the improved calculations will be presented at the conference.
