CAD-based Monte Carlo program for integrated simulation of nuclear system SuperMC

Abstract

a b s t r a c tMonte Carlo (MC) method has distinct advantages to simulate complicated nuclear systems and is envisioned as a routine method for nuclear design and analysis in the future. High-fidelity simulation with MC method coupled with multi-physics phenomena simulation has significant impact on safety, economy and sustainability of nuclear systems. However, great challenges to current MC methods and codes prevent its application in real engineering projects. SuperMC, developed by the FDS Team in China, is a CAD-based Monte Carlo program for integrated simulation of nuclear systems by making use of hybrid MC and deterministic methods and advanced computer technologies. The design objective, architecture and main methodology of SuperMC are presented in this paper. SuperMC2.1, the latest version, can perform neutron, photon and coupled neutron and photon transport calculation, geometry and physics modeling, results and process visualization. It has been developed and verified by using a series of benchmarking cases such as the fusion reactor ITER model and the fast reactor BN-600 model. SuperMC is still in its evolution process toward a general and routine tool for the simulation of nuclear systems.

Selecting benchmarks for reactor simulations: An application to a lead fast reactor

“…The Super Monte Carlo Simulation Program for Nuclear and Radiation Process (SuperMC) code (Wu et al, 2015) developed at the Institute of Nuclear Energy Safety Technology (INEST), Chinese Academy of Sciences, and the OpenMC code (Romano et al, 2015) developed by the Computational Reactor Physics Group at the Massachusetts Institute of Technology (MIT) are examples. These codes are usually developed with target applications in mind.…”

“…traditionally been very expensive and time-consuming (Cacuci and Ionescu-Bujor, 2010). In Zhang et al (2016) for example, a validation suite from the International Handbook of Evaluated Criticality Safety Benchmark Experiments was used for validating the SuperMC code (Wu et al, 2015).…”

Optimal Spatial Subdivision method for improving geometry navigation performance in Monte Carlo particle transport simulation

“…Therefore, reduction in number of searched geometric objects for performing particle location calculation is the key aspect for optimization in this paper. The method has been implemented and integrated into the Super Monte Carlo program (SuperMC) (Song et al, 2014;Sun et al, 2013;Wu et al, 2014), which is a CAD-based multi-functional simulation system for nuclear and radiation process (Wu et al, 2011;Wu, 2008Wu, , 2007. The program SuperMC, which integrates automatic modeling (Hu et al, 2007;Li et al, 2007;Wu, 2009), multi-physics simulation and visualized analysis as a systematical system, based on hybrid Monte Carlo and deterministic transport methods (Chen et al, 2014;Wu et al, 1999), is designed to perform radiation transport, isotope burn-up and material activation simulations (Huang et al, 2009(Huang et al, , 2004.…”
