Abstract: Based on the analysis of the pre-stressing installation process for pressure vessel bolts in nuclear power plant, a method of using statistical process control（SPC） technique for the analysis of the bolt pre-stressing was proposed, and an automatic data acquisition implementation scheme was designed. Data analysis results demonstrated the accuracy of the method, and it can be used to analyze the pre-stressing and evaluate the quality of the pressure vessel installation in nuclear power plant.
