Abstract
VTT is currently working on the development of the deterministic computer code REMS for reactor dosimetry calculations. The transport solution in REMS is based on a response-matrix formalism, with multi-group responses pre-computed by Serpent 2. In this sense, the Serpent-REMS sequence embodies a two-step approach. Reaction rates for three threshold nuclear reactions were calculated by REMS and compared against measured values in the context of the VENUS-3 benchmark experiment. For the 383 experimental values available, the average and standard deviation of calculated-to-experimental reaction rate ratios were (1.03 ± 0.11). This work also reports on the ongoing validation of the Monte Carlo code Serpent 2 for reactor dosimetry applications. The VENUS-3 benchmark problem was also calculated with Serpent 2. The average reaction rate ratios and standard deviations were (1.02 ± 0.06). Execution times for REMS are considerably lower than those of Serpent 2. Furthermore, parallel scalablitity tests suggest promising prospects for the solution of multi-step irradiation scenarios with REMS. Future work will focus on means of improving the accuracy of the REMS solution by refining the Serpent 2 models used in response-matrix generation, as well as on uncertainty qualification.
