Welding Safety Management Review System for Electric Structures of Nuclear Power Stations in Japan

Abstract:

Previously, object-oriented inspections have been conducted by the regulatory authority for the welding of electric power generating equipment (hereinafter referred to as “electric structures”) of nuclear power stations in Japan. However, the law related to the welding was recently amended and enforced. The soundness of the welding of the electric structures is verified in a manner that the regulatory authority reviews the utilities’ implementation conditions of welding inspections instead of directly inspecting the welded joints by the authority. This report presents an outline of the Welding Safety Management Review System, which is a review-type inspection.
