国内三代EPR核电常规岛技术特点

我国目前在建的台山核电站采用了欧洲压水堆（European pressurized water reactor，EPR）三代核电技术，其单机容量世界最大。通过对EPR机组与AP1000、CPR1000 等机组进行对比分析表明，EPR机组在初投资、运行费用方面等方面都具有优势。对台山核电站EPR常规岛的系统和布置特点进行了阐述，介绍了其采用地下2 层、地上2 层的半地下式布置，以及取消除氧间和采用立式汽水分离器再热器等布置方案。本研究可为压水堆核电机组以及大容量直流冷却机组的设计提供借鉴。

Technical Features of Third Generation Nuclear Power EPR Conventional Island

Taishan nuclear power plant under construction adopts European pressurized water reactor(EPR)-the third generation nuclear power type,which has the largest capacity in the world.Compared to AP1000 and CPR1000,the EPR has the advantage in initial investment and operating cost.The paper describes the system configuration and arrangement scheme of Taishan nuclear power plant.The Taishan EPR nuclear power plant adopts a semi-underground arrangement that the turbine hall has two floors above ground and two floor...
