Abstract: This article focuses on analyzing the causes, harmfulness, and characteristics of fires in the comprehensive pipe gallery of nuclear power plants. It compares and analyzes the advantages and disadvantages of various fire extinguishing methods set up in the comprehensive pipe gallery. Combined with high—pressure water mist physical fire extinguishing tests, a high—pressure water mist fire extinguishing system is used in the underground comprehensive pipe gallery of a certain nuclear power plant in China. This research achievement and practice have certain reference value for the safety production of nuclear power plants.

Key words: nuclear power plant, comprehensive pipe gallery, cable fire, high pressure water mist
