Scope

Scope: This document specifies the technical requirements for visual inspection during the manufacturing and installation of pressure-bearing components in pressurized water reactor nuclear power plants. This document applies to visual inspection of materials, components, welded joints, and equipment surfaces in pressurized water reactor nuclear power plants, used to determine the surface condition of the inspected workpieces, the alignment of mating surfaces, deformation or leakage, and integrity. Visual observations involving the identification of other non-destructive testing results are not within the scope of this document. Main technical content: This document is Part 7 of T/CNEA 103 "Non-Destructive Testing of Pressurized Water Reactor Pressure-Bearing Components". This document consists of 9 chapters, of which Chapters 1-3 are normative provisions, and Chapters 4-9 are the main content of Part 7: Visual Inspection of Pressurized Water Reactor Pressure-Bearing Components. The main content includes: general requirements, visual inspection equipment and instruments, visual inspection methods, inspection process, evaluation and recording, and inspection reports.
