TIG Welding Testing of Ferritic Steel and SUS316 Steel

Contracting organization: 国立研究開発法人日本原子力研究開発機構

1. Items Subject to Bidding Subject Name: TIG Welding Testing of Ferritic Steel and SUS316 Steel Overview: The Japan Atomic Energy Agency (JAEA) is advancing the development of core components required for fast reactors, which are effective for reducing the volume and radiotoxicity of radioactive waste. As part of this, ferritic steel is being developed as wrapper tubes for fuel assemblies, and the development of dissimilar metal welding technology for it is also underway. This project involves conducting TIG welding using Ni-based filler and post-weld heat treatment on ferritic steel plate m…
