某多用途小型堆核岛消防系统设计与研究

Design and research on fire protection system of a small multi-purpose nuclear island

核岛厂房是核电厂运行的核心组成部分,其具有保护物项种类复杂、安全级别高、火灾危险性大、辐射剂量高、救援人员难以接近等特殊性,做好核岛消防系统设计对于整个核岛的安全运行至关重要。结合某多用途模块式小型压水堆工程实例,详细介绍了核岛消防系统的设备选型、水力计算及设计要点,并对其缓解核安全事故的应用进行了探讨,以期为其他同类工程设计提供思路与参考。

Nuclear island building is the core component of nuclear power plant operation,which has characteristics of complex types of protection items,high safety level,high fire risk,high radiation dose and difficult for rescue personnel to approach,therefore,the design of nuclear island fire protection system is very important for the safe operation of the whole nuclear island.The equipment selection,hydraulic calculation and design key points of nuclear island fire protection system were introduced in detail based on a project example of a small multi-purpose modular pressurized water reactor,and its application in mitigating nuclear safety accidents was discussed in order to provide ideas and references for other similar projects.
