Background: It requires much computational time with acceptable statistics errors in reactor simulations including fission reactors and fusion-fission hybrid reactors
which has become one challenge of the Monte Carlo method. Purpose: In this paper
an efficient parallel computing method was presented for resolving the communication deadlock and load balancing problem of current methods. Methods: The parallel computing method based on bi-directional traversal of criticality calculation was implemented in super Monte Carlo simulation program (SuperMC) for nuclear and radiation process. The pool-type sodium cooled fast reactor BN600 was proposed for benchmarking and was compared with MCNP. Results: Results showed that the parallel method and un-parallel methods were in agreement with each other. Conclusion: The parallel efficiency of SuperMC is higher than that of MCNP
which demonstrates the accuracy and efficiency of the parallel computing method. Abstract
