Research on Reactor Internals Sealing Structure of Supercritical Water Cooled Reactor

Science and Technology on Reactor System Design Technology Laboratory, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 为实现中国超临界水冷堆(CSR1000)双流程设计方案,反应堆内部需要设置多处密封结构。鉴于电厂压水堆及其他行业在密封结构上的使用经验,"O"形环、"C"形环用于CSR1000堆内构件密封设计是可行的,通过有限元软件ANSYS模拟密封环的受载情况,并对压缩量及回弹量等关键参数进行计算分析。

Abstract: In order to realize the dual process design of China supercritical water cooled Reactor（CSR1000）,it is necessary to set sealing structure in more than one place inside the reactor.In view of the use experience of the sealing structure in the power station PWR and other industries,it is feasible for the use of O-ring and C-ring in the seal design of the CSR1000 reactor internals.The loading situation of the seal ring is simulated and some key parameters such as decrement and springback amount are calculated and analyzed by taking O-ring for example.
