采用三维离散纵标(SN)方法程序TORT计算了CAP1400核电厂堆内构件发热率,并将计算结果与蒙特卡罗(MC)方法程序MCNP以及两维SN方法程序DORT计算结果进行比较。在针对反应堆模型进行屏蔽设计时,需求解固定源问题,应用西屋公司开发的SORCERY程序将pin by pin堆芯功率分布转换为三维源分布。由于CAP1400反应堆模型较大,固定源的制作会消耗大量的计算机硬件资源,同时也会超出SORCERY程序本身的计算规模限制,为此开发了外源制作辅助程序PSOR,使TORT程序适用于CAP1400等大规模工程问题的计算。
The rate of heat generation in the reactor of CAP1400 nuclear power plant was calculated by TORT, a three-dimensional Discrete Ordnance (SN) method program. The calculated results were compared with MCNP of Monte Carlo method and DORT of two-dimensional SN method. When designing shield designs for reactor models, solves the problem of pinned sources, and converts the pin-pin core power distribution to a three-dimensional source distribution using the SORCERY program developed by Westinghouse. Due to the large CAP1400 reactor model, the fixed source production consumes a large amount of computer hardware resources and also exceeds the computational scale limitation of the SORCERY program. For this reason, an extrinsic assistance program PSOR has been developed to make the TORT program suitable for large CAP1400 Calculation of scale engineering problems.
