中国一体化反应堆核电厂创新安全壳设计研究

Research and Design of China Intehral Reactor Plant Innovative Containment

中国一体化反应堆核电厂(CIP)是中国核反应堆系统设计技术国家重点实验室正在开发的新一代革新型、完全一体化的压水堆,其电功率约为300MW。CIP采用堆内一体化布置,反应堆冷却剂系统设备以及控制棒驱动机构全部布置在反应堆压力容器内。这种一体化设计消除了传统的冷却剂回路管道,消除了大LOCA事故,具有更高的安全性。本文介绍了CIP安全壳系统方案选择、安全壳设计、安全壳设计压力的确定以及安全壳结构的计算分析。

China Integral Reactor Plant （CIP） is a light water cooled, 300MWe power reactor under development by Chinese National Key Laboratory of Reactor System Design Technology. CIP features an integral reactor vessel that contains the CRDM and all the major reactor coolant system components including the reactor core, the coolant pumps, the once-through steam generators and the pressurizer. This integral design approach eliminates the large coolant piping and large LOCAs, and thus provides with higher level of securities. This paper introduces the selection of the CIP containment system, the design of containment, the determination of the design pressure for the containment and the calculation analysis of the containment structure.
