【摘要】 目前，国内核设施通风系统问题时有出现，为了解我国核设施通风系统现状，降低放射性粉尘和气溶胶、化学有害因素、高温等危害对人体健康的影响，本文以核燃料元件厂为例综述了我国核设施通风系统全流程各阶段（设计审核阶段、施工安装阶段、调试阶段及运行维护阶段）可能存在的几点问题，并提出了改善对策。现阶段国内核设施的环境质量仍有待进一步提升，企业需要更加重视厂房通风管理，对可能发生的隐患尽快整改，保证通风设施高效运行，从而改善厂房内空气环境，降低职业病发病率。更多还原

【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.更多还原
