摘　　要：本文介绍了5MW 低功率堆(5MW LPR)主屏蔽辐射场和温场的计算模型、方法和程序,给出了修改设计的主要计算结果。混凝土屏蔽层内表面的入射中子通量和γ通量均满足设计标准规定。最高温度、最大温升及最大温度梯度亦均符合规定要求。为证明温场程序的可靠性,将HFETR 混凝土屏蔽层内温度计算值与实测值作了比较,结果符合得很好。This paper present the model,the method and the codes ofradiation field and temperature field calculations in bulk shieldingdesign of the 5MW Low Power Reactor.The main results of revi-sed design calculation are listed.Both incident neutron flux andgamma flux on the inner surface of the concrete shield meet thedesign criteria.The highest temperature,the maximum temperat-ure rise and temperature gradient meet the requirements of thecriteria.In order to verify the reliability of the temperature fieldcode,the calculation results are compared with results at the in-ner surface of HFETR's concrete shields.The agreement is good.
