燃料组件在地震和失水工况下的结构动力反应分析
|
摘要
反应堆堆芯燃料组件是核电厂中的核心部件,在核电厂地震和失水事故联合作用下进行详细动力分析与评定,是核电厂设计规范和安全评审的要求。本研究重点是在近20年有关燃料组件地震加失水事故下反应分析和试验研究基础上进行的综合性研究,形成完整的分析和评定系统。该研究成果已成功地应用在秦山、PC两座核电厂的设计分析和安全评审中,对我国自主开展百万千瓦级先进压水堆核电厂主设备在地震加失水事故下的设计和安全分析具有良好的推广和应用前景。
The fuel assemblies are the kernel components in the NPP. The detail dynamic analysis and evaluation, under combined application of the earthquake and LOCA loads, are the requkements of design codes and safety review. The emphasis of the research is to perform a comprehensive investigation so as to develop and form a complete analysis and evaluation system, based on recent 20 years' response analyses and tests of the fuel assemblies under the earthquake and LOCA accidents. The research results have successfully applied on the design analysis and safety review for Qinshan and PC NPPs, and also having glorious expectation for the design and safety analysis of the fuel assemblies under the earthquake and LOCA accidents on the domestic self-developed 1000 MWe advanced PWR.
