EPR三代核电厂廊道设计

核电厂廊道是实现厂区内各厂房之间管道、电缆连接以及人员通行的地下通道，其数量众多，功能复杂，设计要求多样，目前在建的核电机组的廊道设计国内还未有针对性的设计规范。结合台山电厂欧洲压水堆（Europe pressure-water reactor, EPR)三代核电机组廊道设计实践，详细介绍了该型核电机组廊道的特点、基本功能及主要设计内容，分析了EPR三代核电机组廊道设计思路及方法，针对工程中出现的实际问题提出了设计优化思路及建议。该实践经验可为国内其他类似大型核电厂的廊道设计提供借鉴，也可为国内完善相关设计规范提供参考。

Gallery Design for EPR Nuclear Power Plant

There are many galleries with different functions and design requirements in nuclear power plant（NPP）,which are set for linking the pipes and cables between the workshops and providing the accesses for personnel,but there is not specific gallery design code for the 3rd Generation NPP in China at present.Combined with the gallery design in Taishan Europe pressure-water reactor（EPR） NPP,the characteristic,basic functions and main design contents of galleries were described in detail,and the method and design idea of the gallery were proposed for EPR NPP.This paper suggests some optimization approaches for gallery engineering design,which will provide references for the follow-up NPP and promote the establishment of design code.
