在分析核电厂反应堆压力容器螺栓预应力安装工艺的基础上,提出使用统计过程控制(SPC)技术对螺栓预应力进行分析的方法,并设计一种可以自动采集数据的实现方案。数据分析结果证明方法准确,可用于核电厂压力容器螺栓安装的预应力分析和质量评价。
Based on the analysis of prestress installation process of reactor pressure vessel in nuclear power plant, a method to analyze the bolt prestress by using statistical process control (SPC) technology is proposed and a scheme of data acquisition is designed. The data analysis results show that the method is accurate and can be used for the prestress analysis and quality evaluation of the bolt installation of pressure vessel in NPP.
