【Abstract】 Hydrostatic test for RPV is not only a means to inspect the vessels and the associated systems but also an important way to verify the results of mechanical analysis. The loading obtained by measurement is useful for the establishment of loading spectrum. In this paper, some discussions on the shop hydrostatic test planning for the RPV of Qinshan NPP performed in Japan are presented. Comparisons between the results of hydrostatic test provided by vendor and those of primary system hydrostatic test conducted at Qinshan Site are also given. Some data obtained at Qinshan Site such as actual loading and technical data of the stud - bolt, are listed. The results of measurement for the flange rotation, important for the sealing characteristics of RPV, are specifically discussed. This paper points out some of the mistakes in the results of the shop hydrostatic test.更多还原
