大亚湾核电站的环境评估及其监督

Environment Estimation and Supervision on Daya Bay Nuclear Power Plant

为了全面掌握核电站建设对周边环境产生的影响，广东大亚湾核电站在选址、可行性研究、建造和营运的各个阶段均制定了详细的环境监测计划。文中较全面地介绍了电站运行前的环境放射性本底水平调查和电站的环境监测系统。经几年来的运行和监测结果表明：电站周围陆上环境的放射性水平与电站投产前相比，无显著差异，通过气态途径释放的放射性物质未对周围环境产生任何影响。

In order to comprehensively master the impact of nuclear power plant construction on the peripherial environment, Daya Bay Nuclear Power Plant in Guangdong Province formulated detail environment monitoring plan during various stages of selection of site, feasibility study, building and operation.This paper completely introduces the investigation of environmental radioactive background level before the commissioning of power plant and environment monitoring system of power plant.The operation and monitoring results over the past several years indicate that, there is no distinct difference in radioactive levels of peripherial ferrestrial environment before and after the commissioning of power plant, the radioactive matter released through gaseous path hasn't any impact on the surrounding environmet.
