摘　　要：本文从审评遇到的实际问题出发,给出了核电厂应急给水系统多样性设计的相关规定,介绍了各种不同应急给水系统的设计,以及不同配置在多样性问题上的考虑,最后从全厂断电及共模故障的基础上论证了应急给水系统多样性设计的必要性。From the practical problems encountered during the reviews, the relevant code provisions and regulations about the diversity of urgent water supply systems are promoted. Considering the diversity of the systems, this paper introduces various designs of urgent water supply systems for nuclear power plants. Finally, the necessity of designing various emergency water supply systems is demonstrated from the situations of station blackout and the common mode failure.
