CPR1000核电厂应对超设计基准全厂断电增设移动电源的研究与设计

Research and Design of Mobile Electricity Generators Added for CPR1000 NPP Station Blackout

福岛核事故的经验反馈表明,超设计基准的长时间全厂断电可能发生,核电厂有必要增设移动电源。本文从CPR1000核电厂的电源配置出发,结合福岛核事故经验反馈,讨论极端自然灾害带来的全厂断电风险,分析确定增设移动电源的必要性及其功能定位。针对全厂断电工况下必须保持供电的负荷进行研究,以确定移动电源的合理功率。分析介绍目前移动式应急电源的分类以及优缺点,并根据核电厂应用的具体需求,选择合适的电源类型,最后,指出核电厂移动电源设计的关键要素并给出相关的设计建议。

Long-drawn station blackout may occur from the Fukushima nuclear accident experience feedback,so it is necessary to add mobile electricity generators for NPP.This paper firstly analyzes CPR1000 NPP's power configuration,then discusses the station blackout risk due to extreme natural disasters from the Fukushima nuclear accident experience feedback,whereafter fixes the functional orientation and essential loads of the mobile electricity generators,and then determines the reasonable power.This paper also describes the classification,advantages and disadvantages of mobile electricity generators,and recommends the appropriate type of power according to the specific needs of the NPP.Finally,it points out the key elements and advices for the design of mobile electricity generators.
