摘　　要：针对模块式高温气冷堆(MHTR)钢制压力容器存在着制造难度大、运输困难和成本高等缺点,开展了对MHTR采用预应力混凝土压力容器(PCPV)的可行性研究。本文简要介绍了PCPV的发展现状与技术特点,分析研究了MHTR采用PCPV作为一回路压力边界部件的技术难点及可行性,给出了MHTR采用PCPV的初步设计方案。对该方案的分析结果表明,将PCPV应用于MHTR在技术上是可行的,不仅能够解决多腔室PCPV的力学问题以及反应堆余热释放等关键技术问题,而且能使MHTR具有更好的安全性和经济性。Considering the disadvantages of the steel pressure vessels in modular high temperature gas-cooled reactor (MHTR), such as high cost and difficulties in manufacture and transportation, the technical feasibility study is performed for the pre-stressed concrete pressure vessel (PCPV) in MHTR. The paper briefly presents the development status and technical characteristics of PCPV, analyzes and studies the technical crux and feasibility of PCPV as the primary system pressure boundary components of MHTR. The preliminary design of PCPV is proposed for MHTR. The analysis proves that PCPV utilized in MHTR is feasible, which could not only solve the technical crux, such as mechanics problems and decay heat removal in the multi-cavity of PCPV, but also improve the economic competition and safety of MHTR.
