基于台山核电厂中子剂量监测实践的思考

Some thoughts on neutron dose monitoring practice at Taishan Nuclear Power Plant

介绍了台山核电厂近几年来开展的中子辐射监测以及中子剂量监测的相关实践,并基于实践情况开展了中子剂量监测的合规性分析,讨论了国内外法规和标准针对核电厂中子剂量监测的要求。分析认为,台山核电厂近年来对中子辐射开展的剂量监测实践符合国内相关法规和标准的要求,但是也发现目前国内针对核电厂中子辐射监测的法规和标准中未明确需要开展中子个人剂量监测的起测标准,国际原子能机构的一般安全导则以及国外部分国家在核电厂中子剂量监测方面有相对更明确的规定。建议我国相关部门针对核电厂中子剂量监测考虑补充相关指导条款,各核电厂应针对自身情况开展中子剂量监测评价。

This article introduces the practices of neutron radiation monitoring and neutron dose monitoring carried out by Taishan Nuclear Power Plant in recent years,and conducts compliance analysis of neutron dose monitoring based on the practical situation.This article also discusses the requirements of domestic and foreign regulations and standards for neutron dose monitoring in nuclear power plants.Analysis suggests that the dose monitoring practices carried out by Taishan Nuclear Power Plant for neutron radiation in recent years comply with relevant domestic regulations and standards.However,it is found that the current regulations and standards for neutron radiation monitoring in nuclear power plants in China are not yet complete.The IAEA general safety guidance and some foreign countries have relative cleare regulations on neutron dose monitoring in nuclear power plants.This article suggests that relevant organizations in China should consider developing relevant guidance standards for neutron dose monitoring in nuclear power plants,and each nuclear power plant should conduct neutron dose monitoring and evaluation based on its own situation.
