Abstract: A fault tree model, for radiation safety of nuclear flaw detection in the field of nuclear power construction projectshas been set up, by using which the relevant risk has been fully analyzed. Combined with the specific requirements of relevant laws, regulations and standardsof radiation protection in China, a set of complete control measures of radiation detection of nuclear power construction site is formulated in accordance withthe operation process flow, by reference to the practices of Bechtel, FA3 and other companies. It is aimed at eliminating the occurrence of safety incidents both through the management system and via technical means, and standardizing the radiation safety protection and management of radiofrequency detection in the construction of nuclear power projects.

Key words: Nuclear power project, Construction site, Radiofrequency detection, Radiation safety
