Implementation and optimization of WDT algorithm on IMPC-Neutron and comparison of efficiency of various algorithms

In Monte Carlo code, the use of Delta-tracking algorithm can greatly improve the computational efficiency, but the existence of virtual collision will waste computing resources because the virtual collision introduced by Delta-tracking algorithm does not make any contribution to the statistical resu...

520			\|a In Monte Carlo code, the use of Delta-tracking algorithm can greatly improve the computational efficiency, but the existence of virtual collision will waste computing resources because the virtual collision introduced by Delta-tracking algorithm does not make any contribution to the statistical results. The Weighted Delta-tracking algorithm makes the virtual collision contribute to the statistics and improves the efficiency of Delta-tracking algorithm. We implemented Weighted Delta-tracking algorithm into the IMPC-Neutron code, then we optimized the Weighted Delta-tracking algorithm to improve its computational efficiency, and analyzed the effects and limitations of Weighted Delta-tracking algorithm in different assemblies. The optimal parameters of Weighted Delta-tracking algorithm are tested in the full reactor models of PWR core and sub-critical fast reactor core. Finally, the calculation efficiency of various neutron transport methods is compared by using IMPC-Neutron.

The Weighted Delta-tracking algorithm makes the virtual collision contribute to the statistics and improves the efficiency of Delta-tracking algorithm. We implemented Weighted Delta-tracking algorithm into the IMPC-Neutron code, then we optimized the Weighted Delta-tracking algorithm to improve its computational efficiency, and analyzed the effects and limitations of Weighted Delta-tracking algorithm in different assemblies. The optimal parameters of Weighted Delta-tracking algorithm are tested in the full reactor models of PWR core and sub-critical fast reactor core.

abstract	In Monte Carlo code, the use of Delta-tracking algorithm can greatly improve the computational efficiency, but the existence of virtual collision will waste computing resources because the virtual collision introduced by Delta-tracking algorithm does not make any contribution to the statistical results. The Weighted Delta-tracking algorithm makes the virtual collision contribute to the statistics and improves the efficiency of Delta-tracking algorithm. We implemented Weighted Delta-tracking algorithm into the IMPC-Neutron code, then we optimized the Weighted Delta-tracking algorithm to improve its computational efficiency, and analyzed the effects and limitations of Weighted Delta-tracking algorithm in different assemblies. The optimal parameters of Weighted Delta-tracking algorithm are tested in the full reactor models of PWR core and sub-critical fast reactor core. Finally, the calculation efficiency of various neutron transport methods is compared by using IMPC-Neutron.
