摘　　要：采用一体化布置、全功率自然循环冷却和紧贴式双层承压壳的核供热堆具有固有安全性和良好的经济性 ,但同时也带来了大型薄壁容器套装的新课题。该文以系统工程的方法和观点全面分析了压力壳、钢安全壳套装的关键技术问题 ,在国内外均无可借鉴经验的情况下提出套装工艺 ,并在已投入运行的 5 MW低温堆工程中得到应用。应用结果表明该套装工艺安全、可靠 ,具有良好的可操作性和独创性。对反应堆压力容器套装工艺的研究 ,对于积累核设备设计、制造和安装经验 ,制定相应的技术标准 。The Nuclear Heating Reactor (NHR) has the advantages of inherent safety and better economics, integrated arrangement, full power natural circulation and dual vessel structure. However, the large thin container presents a new and difficult problem. The characteristics of the dual vessel installation method are analyzed with system engineering theory. Since there is no foreign or domestic experience, a new method was developed for the dual vessel installation for the 5MW NHR. The result shows that the installation method is safe and reliable. The research on the dual vessel installation method has important significance for the design, manufacture and installation of the NHR dual vessel, as well as the industrialization and standardization of the NHR.
