提升核电厂核空气净化系统可靠性的策略研究

Strategy Study on Improving the Reliability of the Nuclear Air Cleaning System of NPP

核电厂核空气净化系统的性能关乎事故工况下主控室可居留性和电厂排气放射性水平,其运行的可靠性受系统管路的密封性、碘吸附器性能、高效过滤器性能、电加热器控制策略、火灾报警正确率等方面的影响。本文从系统可靠性相关的各个方面进行研究并提出改进策略,以期提高核电厂核空气净化系统的运行可靠性。

The inhabitability of the main control room during accident situations and control of radioactivity release are related to the performance of the nuclear air cleaning system of nuclear power plant,their operation reliability is affected by the leak-tightness of ductworks,performance of iodine absorbers and HEPA filters,control strategy of electrical heaters,correctness of the fire detection system and so on.Some studies on related aspects are carried out and improving strategies are addressed in this paper for enhancing the operation reliability of the nuclear air cleaning system of nuclear power plant.
