Research on New Conceptual Design of PWR Core Catcher
-
摘要: 根据福岛核事故经验,总结了未来堆芯捕集器的设计目标,提出分组捕集(CGC)、强制铺展(WCC)及引流冷却(CCC)3种新概念堆芯捕集器方案。梳理了欧洲先进压水堆(EPR)及俄罗斯水-水高能反应堆(WWER)2种典型堆芯捕集器的技术特点,并对3种新方案的性能倾向进行了评估。结果表明,新方案具有明显的技术优势。Abstract: Based on the experience of Fukushima accident, this paper analyzed two typical core catcher designs, from EPR and WWER, and put forward three new conceptual schemes, i.e., the core grouping catcher, the Waffle core catcher, and the casting core catcher. The conclusion shows that the new schemes have obvious technical advantages.
