Abstract

Abstract

During the manufacture and installation of reactor pressure vessel bolt hole and bolt, the existence of defects is inescapable. The analysis results show that most of the defects have no effect on the function and safety of the structure. This paper summarizes some kinds of defects of bolt hole and bolt. The received conditions and evaluation technology are provided here.
- Bolt hole,
- Bolt,
- Defect
