三代核电站主控室应急可居留系统解析
Emergency habitability system for main control room of AP1000 third generation nuclear power plant
摘要：
基于主控室应急可居留系统在核电站设计基准事故下的重要功能，对AP1000三代核电站主控室应急可居留系统功能进行解析，总结了系统在构造设计、非能动功能实现、压力边界维持方面的基本设计要求。结合国内其他核电站相应系统的设计，探讨了应急可居留系统的新风引入、系统布置设计同辐射防护的关系，并参照ASME AG1分析了管段泄漏分级对碘防护因子的影响。
Abstract：
Based on the important function of main control room emergency habitability system in the case of nuclear power design basis accident, analyses the system functions of AP1000 third generation nuclear power plant，and summarizes the basic design requirements for construction design, passive function realization and pressure boundary maintenance. Combined with the similar systems of other domestic plants, discusses the relationship between outdoor air supply, system layout design and effect of radiation protection, and analyses the influence of leakage classification on iodine protective factor according to ASME AG1.
