Modular ray tracing in 2D whole core transport with MOC

摘要

2D modular ray tracing algorithms for the solution of neutron transport via the method of characteristics (MOC) is developed and implemented in the Shiraz University Integrated Advanced Neutron Transport Simulator (SAINTS) code. In SAINTS, a flexible modular cyclic ray tracing which produces track information in a combinatorial geometry is developed. To validate the code, C5G7 standard benchmark is used to calculate multiplication factor and pin powers. Comparison of the SAINTS results with the reference data from NEA C5G7 benchmarks indicates a good agreement and acceptable execution time. SAINTS
