摘　　要：建造聚变堆必须要考虑核安全系统的设计,聚变堆最大的安全问题是高能中子和氚的包容。对磁约束聚变堆的特点进行了分析,提出了磁约束聚变堆的核安全功能、核安全系统组成,包括包容系统、多层屏蔽以及包容的保护功能、支持功能;探讨了氚防护措施;针对现有核安全标准中安全部件分级方法对于聚变堆过于复杂,提出了一种新的分级方法,针对聚变设施上的纵深防御层次给出了每一层次对应的目标和措施。可对未来聚变堆的核安全系统设计提供参考。The design of nuclear safety systems must be considered in the construction of fusion reactors.The biggest safety issue for fusion reactors is the inclusion of high-energy neutrons and tritium.The characteristics of the magnetic confinement fusion reactor are analyzed,and the nuclear safety function and its system compositions are proposed,including the confinement system,multi-layer shielding,protection and support functions of the confinement.Tritium protection measures were discussed;In view of the fact that the classification method of safety components in the existing nuclear safety standards is too complex for fusion reactors,a new classification method is proposed.For the defense-in-depth level on the fusion facility,the corresponding objectives and measures for each level are given.This paper can provide a reference for the design of nuclear safety systems for future fusion reactors.
