摘　　要：针对月球特殊使用环境下的反应堆辐射屏蔽问题,采用蒙特卡罗方法的MCNP程序对月球反应堆建立了月壤屏蔽和全集成屏蔽两种计算模型。利用MCNP程序对航天员所受剂量和斯特林电机所受通量进行了详细计算,给出月壤屏蔽和全集成屏蔽优化设计的建议。计算结果表明:两种屏蔽方案均能满足剂量限值要求,屏蔽优化设计合理可行。Considering the reactor shielding under lunar special environment,two calculation models,including regolith shielding and material shielding,were established using MCNP code. The dose of astronauts and stirling generator was detailly calculated with MCNP code. And recommendations for optimization of these two designs were given. The results showed that both two shielding designs could meet the dose limit requirements. The shielding optimal design is reasonable and practicable.
