摘要
介绍JMCT(J Monte Carlo Transport)软件的多群中子伴随输运功能以及基于伴随通量的自动源偏倚抽样功能.对某商用压水堆屏蔽模型的模拟计算表明,采用自动源偏倚后,JMCT的模拟结果与实验值符合较好,比MCNP程序采用几何重要性方法的计算效率大幅提高.
Multigroup neutron adjoint transport and automatic source particle biasing sampling function of JMCT is introduced. A press water reactor shielding neutron flux is achieved by JMCT with source biasing sampling technique, which is well accord with experiment. Its computation efficiency is higher than that of MCNP using geometry important method.
