CAD-based interface programs for fusion neutron transport simulation

摘要

Describing and verifying of the models for three-dimensional (3D) neutron transport simulation based on Monte Carlo (MC), discrete ordinates (Sn) and MC-Sn coupled methods are time-consuming and error-prone. The conversion algorithm and corresponding CAD-based interface programs have been developed to achieve the bi-directional conversion between commercial CAD systems and the neutron transport simulation codes including MCAM program for MC simulation, SNAM program for S_n simulation and RCAM program for MC-Sn coupled simulation. This paper introduces the main functions of the three interface programs and a benchmark test based on the ITER model.
