Research on Firefighting Power Supply and Distribution System for Passive Nuclear Power Plant's Nuclear Island
This paper explores the optimization of the passive nuclear power plant's nuclear island fire-fighting power supply and distribution system,as well as the scope of application for fire-resistant cables and dual-breaker devices,based on a deterministic fire hazard analysis.The study clarifies the basic objectives and assumptions,and conducts a detailed analysis of the main fire-fighting electrical loads of the passive nuclear power plant,including fire pumps,smoke exhaust fans,fire alarm controllers,and emergency lighting systems.For different fire-fighting electrical loads,specific recommendations for power source configuration and cable type optimization,as well as a scope of application table,are proposed to guide the actual system optimization.
