Abstract

Abstract

This paper took the world's first HPR1000 nuclear power plant(NPP) of Fuqing 5 unit and Pakistan K2 unit in Karachi as the research object. Firstly, based on the ABAQUS finite element model, the overall test and theoretical analysis of containment structure of the HPR1000 NPP were carried out, the damage process of the containment structure under the LOCA accident was studied, and the weak links of the containment were clarified. According to NB/T 20017-2010 "Structural Integrity Test of Containments of Pressurized Water Reactor Nuclear Power Plants", the displacement test data of SIT test was analyzed, and the rationalization suggestions for the above standards were proposed according to the test process and results. The results showed that the test parameters of Fuqing 5 unit and Karachi K2 unit of NPP had the same trend with the test pressure; the test results were consistent with the theoretical analysis, and the displacement test results of the two units both met the standard design requirements of NB/T 20017-2010. It was suggested to increase the number of measuring points at the expected maximum horizontal diameter deformation and vertical deformation of the cylinder in the supplementary radial deformation measurement in NB/T 20017-2010, and increase the frequency of measuring points and data collection near the gate of the equipment.
