T/CNEA 102.2-2021 Welding of pressure vessel components in pressurized water reactors Part 2: Acceptance of welding materials

Scope

Scope: This document specifies the acceptance requirements for welding materials used in the pressure-bearing components of pressurized water reactors (including core support structures and support members), including requirements for batch division, mechanical property tests, chemical analysis tests, determination of δ ferrite content, intergranular corrosion tests, determination of hydrogen diffusion content, re-inspection, packaging, marking, and acceptance reports, as well as their validity periods. This document applies to welding materials such as electrodes, welding wires, welding tapes, fusible inserts, and fluxes used for carbon steel, low-alloy steel, austenitic stainless steel, and nickel-based alloys in welding and cladding of pressure-bearing components of pressurized water reactors. Other reactor types may refer to this document for use. Main technical content: This document is Part 2 of T/CNEA 102 "Welding of Pressurized Water Reactor Pressure-Bearing Components". The document consists of 10 chapters. Chapters 1-3 are normative provisions, and Chapters 4-10 are the main content of Part 2: Acceptance of Welding Materials for Pressurized Water Reactor Pressure-Bearing Components. The main content includes: General Provisions, Batch Testing, Inspection of Welding Materials, Test Requirements for Welding Materials, Re-inspection, Packaging, Marking, and Acceptance Reports and Their Validity Periods.
