摘　　要：田湾核电站1、2号机组蒸汽发生器为WWER1000堆型卧式蒸汽发生器,它由容器、传热面、一回路冷却剂集流管、主给水分配装置、应急给水分配装置、蒸汽分离孔板和水下均汽板等部件组成。文章重点对WWER1000堆型蒸汽发生器解体检修的辐射防护实践进行介绍,对田湾核电站历次大修现场辐射水平及集体剂量情况进行分析,并提出后续的优化方向。The horizontal steam generator of TNPS（Unit 12, WWER1000） consists of container, heat transfer surface, collectors of coolant,distribution device of main feed water, the emergency feed water distribution device and vapor separation orifices etc. The article elaborates the radiation protection practice of horizontal steam generator overhauling, gives an analysis of site radiation level and personnel collective dose of TNPS previous overhauling, and the follow-up optimization direction is also proposed.
