Abstract:

安全壳是核电厂防止放射性物质泄漏的最后一道屏障，福岛核事故以来，非能动安全壳冷却系统的设计一直是先进核动力反应堆的研究重点。小型反应堆将当前先进的非能动设计与其一体化概念相结合，提出了新的设计理念。本文旨在总结国内外小型模块化反应堆非能动安全壳冷却系统的设计方案，通过不同方案之间的优劣对比，分别提出适合陆上小型堆和海上浮动堆非能动安全壳冷却的设计方案，为我国模块化小型反应堆正在进行的非能动安全壳冷却系统研究提供参考。
Containment is the last barrier to prevent radioactive materials leaking from nuclear power plants. Since the Fukushima nuclear accident, the research of advanced nuclear power reactor has always been focusing on the design of passive containment cooling systems. The small modular reactor combines the advanced passive design with its integrated concept, and proposes new designing concepts. This paper aims to give a thorough introduction about the representative design of small modular reactor passive containment cooling system both in China and abroad. By comparing the advantages and disadvantages of different design, it also gives out optimized solutions for onshore small reactors and offshore floating nuclear power plant, which can be taken as reference for the research of small reactor passive containment cooling system currently studied.
