摘　　要：２００ＭＷ核供热堆具有良好的被动安全特性和先进性，其总的安全目标是在所有可信事故条件下，不必采取诸如屏蔽、疏散、重新安置以及去污等厂外应急措施。从核安全纵深防御的角度，为了再多增加一道安全屏障，设置了二次安全壳。介绍了设置二次安全壳的原因及其功能，讨论了二次安全壳的主要设计特点：设计依据和安全准则，二次安全壳及其隔离系统的设计特点、主要设计参数及系统和设备布置，以及安全分析的主要结果。The 200MW nuclear heating reactor (NHR200) is designed with a number of advanced and inherent safety features. The general safety objective of NHR200 is no offsite emergency actions such as sheltering, evacuation, relocation and decontaimination in case of all credible accidents. In order to add an additional protection from the view point of nuclear safety defence in depth, the secondary containment is adopted. The reasons and functions of the secondary containment are presented. The main design features including the design bases and safety criteria, the main design characteristics of the secondary containment and its isolation system, the main design data and equipment arrangement and the main results of the safety analysis are discussed.
