Scope

Scope: This document applies to the safety assessment of pressure vessels used in the conventional island and supporting facilities (BOP) of nuclear power units, which have reached the design life of the container (or within the next maintenance cycle) or have not been marked with a design life but have been in use for more than 20 years. It stipulates the basic conditions, basic steps, evaluation methods, and grade assessments for safety assessments. Main technical content: This document specifies the inspection and testing requirements for conventional island pressure vessels that exceed the design service life, determines the basic conditions, basic steps, evaluation methods, and grade assessments for safety assessments, and ensures the effectiveness of inspection and testing and the safe operation of nuclear power plants.
