Code for fire protection design of nuclear power plant

1 Scope

This document specifies the basic requirements for the internal fire protection and explosion-proof design of nuclear power plants, mainly including the general requirements for fire protection design and the protection of the general layout. Fire design, fire prevention and limitation of fire spread, fire evacuation, automatic fire alarm system, fire water supply and fire extinguishing system, ventilation, fire prevention and prevention Smoke exhaust, fire safety analysis, internal explosion-proof design, and fire protection design requirements for key areas and equipment, etc. This document is applicable to newly built land-based fixed thermal neutron reactor nuclear power plants in China. Other types of nuclear power plants and nuclear facilities can refer to this regulation. Fan carries on the design. This document is mainly aimed at the internal fire protection of important nuclear safety buildings (structures) (such as nuclear island plants, important plant water system pump rooms and corridors, etc.) And explosion-proof design, the fire protection design of conventional islands and supporting facilities and workshops meets the requirements in Chapter 4, Chapter 5 and Chapter 13 of this document (specially It specifically refers to the requirements of important nuclear safety structures (except for the requirements) on the basis of compliance with other relevant domestic design standards.
