摘要
安全壳是事故后防止放射性释放到环境的最后一道屏障,有效的安全壳冷却可以避免由于大量质能释放到安全壳引发的安全壳超压失效事故。随着安全监管要求的提高和技术的发展,各国都提出了非能动的安全壳冷却方案。本文旨在总结国内外非能动安全壳冷却系统的设计方案和研究成果,并比较分析各方案间的优缺点,分别提出适合钢制和混凝土安全壳非能动冷却的方案,为我国自主设计第三代核电站非能动安全壳冷却系统提供参考。
Containment is the last barrier to prevent radioactive material releasing to the environment after accident,the effective containment cooling can avoid containment overpressure failure accident due to the large mass and energy that released into the containment.With the improvement of regulatory requirements and the development of technology,some passive containment cooling system designs are proposed.The aim of this paper is to summary the design and research results of domestic and foreign passive containment cooling systems.Analysis and comparison of advantages and disadvantages of each scheme are performed.Two suitable passive cooling solutions for steel and double-layer concrete containment are proposed respectively,and it can provide some references for passive containment cooling system of the third generation nuclear power plant in China's independent design.
