Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents"
Drafting.
This document replaces GB/T 22158-2008 "Code for Fire Protection Design of Nuclear Power Plants", compared with GB/T 22158-2008, except for structural adjustments
In addition to editorial changes, the main technical changes are as follows.
a) Added the fire protection design of the general layout (see Chapter 5), fire zone/fire community division requirements (see 6.2), and fire safety analysis
(See Chapter 11), internal explosion-proof design (see Chapter 12), fire protection design requirements for some key areas (see 13.7, 13.13,
13.16, 13.17, 13.18), etc.;
b) Inapplicable regulations such as water seal test are deleted (see Appendix C of the.2008 edition);
c) Modified the general requirements for fire protection design (see 4.4, 4.5), fire evacuation (see Chapter 7), automatic fire alarm system (see Chapter 8), fire protection
Water supply and fire extinguishing system (see Chapter 9), ventilation and fire prevention and smoke prevention (see Chapter 10) and other chapters.

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.
