s: The paper analyzes the characteristics of safety management of nuclear power,Which compromise QA as well as Safety Management System on Nuclear Power Project on the unique QA management analysis tools as the basic method and safety management system。Such as quality assurance, quality assurance audit / quality assurance supervision, for preventing human error, application tools, experience feedback closed-loop management method, Which can improve the level of safety management of nuclear power engineering the construction, but also can improve the quality assurance system. The effective use of analytical tools for the construction of nuclear power which can provide innovative management ideas on the safety management, safety management classification and hidden dangers exclude. The safety management and risk analysis of the trend of the incidence after the integration will be more perfect of QA system。 Summary of experience can be widely used in the field of nuclear power construction projects, but also can promote the safety of key parts of the construction and process system installation and commissioning。
