Abstract: Based on the practical engineering of the CPR1000 Nuclear Power Plant, this paper presents the layout improvement of the containment filtration and exhaust system. System independence of single unit and the aseismic performance is optimized by doubling the systems and improving the arrangement, which promotes the safety performance and reliability after severe accidents. The effect of the improvement and the relevant solutions are also considered. The summary and feasible analysis will offer a reference for the system design of following nuclear power station.
