在分析M310堆型核电站辐射屏蔽设计中由于工具限制存在的问题以及“华龙一号”堆型核电站辐射屏蔽设计提出的要求的基础上,从程序界面、输入接口、计算功能和辐射场应用扩展4个方面提出先进压水堆核电站辐射屏蔽优化设计对于蒙特卡罗(MC)方法的要求。MC方法在“华龙一号”辐射屏蔽优化设计的应用实践表明,基于MC方法的计算程序在程序界面、输入接口和辐射场应用扩展方面进一步提升之后,可在先进压水堆核电站辐射屏蔽优化设计方面发挥巨大的作用,显著提升核电站辐射屏蔽优化设计的水平。

Based on the analysis of the problems resulting from the tool limitations during the radiation shielding design of M310 nuclear power plant and the requirements presented by the radiation shielding design of HPR1000 nuclear power plant,the requirements for Monte Carlo(MC)method during the optimization design of the radiation shielding for advanced PWR nuclear power plant are presented from four aspects,which are the software interface,input interface,dose rate calculation function and radiation field application expansion.The radiation shielding optimization design practice based on MC method in HPR1000 nuclear power plant shows that,by the development of the software interface,input interfaces and radiation field application expansion,the calculation code based on MC method can play a key role in the radiation shielding optimization design of advanced PWR nuclear power plant,and significantly improve the radiation shielding optimization design of PWR nuclear power plant.
