核电厂主设备是核电厂的关键设备。对反应堆堆内构件、控制棒驱动系统、燃料组件和蒸汽发生器传热管等设备进行地震加失水事故联合作用下详细的动力分析与评定,是核电厂设计规范和安全审查的要求。 上海核工程研究设计院在主设备的地震加失水事故下反应分析和试验研究的基础上,将主设备作为一个总体进行分析,从而形成一个完整的分析和评定系统。该研究成果已应用于秦山、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。
Nuclear power plant main equipment is the key equipment of nuclear power plant. Detailed dynamic analysis and assessment of combined actions of reactor internals, control rod drive systems, fuel assemblies and steam generator heat transfer tubes for earthquake and water loss accidents are the requirements of NPP design specifications and safety reviews. Shanghai Nuclear Engineering Research and Design Institute of the main equipment in response to earthquake and loss of water accident response analysis and experimental study based on the main equipment as a whole to analyze and form a complete analysis and evaluation system. The research results have been applied to the design analysis and safety assessment of Qinshan and PC nuclear plants. The design and safety analysis of the main equipment of one millionth advanced pressurized water reactor nuclear power plant in China under earthquake and water loss accident are good The promotion and application prospects.
