T/CNEA 103.3-2021 Nuclear reactor pressure vessel components - Non-destructive testing - Part 3: Radiographic testing (English translation only)
Basic Information
Scope
Scope: This document specifies the technical requirements for the use of X-ray and gamma-ray inspection on pressure-bearing components of pressurized water reactors, as well as the requirements for defect evaluation and quality grading of inspection results. This document applies to the X-ray inspection of cast steel components and steel welded joints during the manufacturing and installation process of pressure-bearing components in pressurized water reactors. The X-ray inspection of other metal materials can be implemented with reference to this document. Main technical content: This document is Part 3 of T/CNEA 103 "Non-destructive Testing of Pressurized Water Reactor Pressure-Bearing Components". This document consists of 10 chapters, of which Chapters 1-3 are normative provisions, and Chapters 4-10 are the main content of Part 3: X-ray Inspection of Pressurized Water Reactor Pressure-Bearing Components. The main content includes: general requirements, main equipment and instruments, inspection technology, film darkroom processing, X-ray negative film quality, defect evaluation and quality grading, and inspection reports.
