Chinese nuclear power standards are parallel due to a variety of technical routes and different technology source countries, resulting in a situation of multiple standards parallel in the domestic nuclear power industry. Through the comparative analysis of nuclear power standards in the United States and France, domestic electric power industry and domestic conventional thermal power industry, this paper seeks for the combination point with domestic nuclear power commissioning standard system, and combs and analyzes the existing standard system. Through industry research and data collection and analysis, combined with the technical characteristics of “Hualong-1”, the requirements and applicability elements of the commissioning standard system are determined, the framework of the commissioning standard system is optimized and improved, and the corresponding standard acquisition, formulation and revision plan of the standard system is formed, so as to guide the construction of commissioning standardization.
