Abstract: At present, problems in the ventilation system of nuclear facilities occur from time to time. In order to understand the current situation of China's nuclear facility ventilation system and reduce the impact of radioactive dust and aerosols, chemical harmful factors, high temperature and other hazards on human health, this paper takes a nuclear fuel element plant as an example to summarize some possible problems in the whole process (design review stage, construction and installation stage, commissioning stage and operation and maintenance stage) of ventilation system in nuclear facilities in China, and puts forward some improvement solutions. It can be seen that the environmental quality of China’s nuclear facilities need to be further improved. Facility operaters need to pay more attention to plant ventilation management, rectify possible hidden dangers as soon as possible, ensure efficient operation of ventilation facilities, so as to improve air environment in the plant and reduce the incidence of occupational diseases.
