'.5 OTHER AUXILIARYSYSTEMS 9.5.1 FIRE PROTECTION SYSTEM The fire protection system (FPS) is designed to detect,
- contain, and extinguish fires in the plant.
The fire protection water supply and pumping equipment" is shared, by all units.
Other, fire protection equipment described below is provided for each unit,individually.
Where referred to in this section, the fire protection 'system includes fire detection and extinguishing'ystems and equip-ment.
It is, exclusive of su'ch design el'ements as 'physical separation, barrier separation, and burning characteristics of combustibles, which limit the propagation of fire, but do not actively extinguish it.
The report "Fire Protection Evaluation for the Arizona Public Service Palo Verde Nuclear Generating Station Units 1, 2 and 3", May 31,
- 1977, as amended August 1978, Docket Numbers STN-50-528, STN-50-529, and STN-50-530, (FPE),
describes and discusses the effects that various postulated ires may have on areas of the plant which contain safety-related structures,
- systems, and components.
This report addresses the requirements of BTP APCSB 9.5-1.
Carpeting is utilized in the PVNGS control room for noise and dust control, to reduce operator fatigue and to enhance the man-machine interface.
The carpeting is listed by a nationally recognized testing laboratory as having a flame spread rating, fuel contribution and smoke density of 25 or less when tested under ASTM E-84.
December'980 9.5-1 Amendmen't
PVNGS FSAR OTHER AUXILIARYSYSTEMS 9.5.1.1.1 Safety Design Bases Safety design bases pertinent to the fire protection system are as follows:
A.
Safety Design Basis One The fire protection system shall be designed to mini-mize, consistent with other safety requirements, the effects of fires on structures,
- systems, and components important to safety, in accordance with 10CFRSO, Appendix A, General Design Criterion 3, Fire Protection.
Amendment 1
9.5-1A March 1980
V OTHER AUXILIARYSYSTEMS B.
Safety Design Basis Two Fire protection systems shall be designed so that their rupture or inadvertent operation does not significantly impair the function of plant structures,
- systems, and components important to safety, in compliance with
- 10CFR50, Appendix A, General Design Criterion 3, Fire Protection.
C.
D.
E.
Safety Design Basis Three Fire protection system components shall be designed to preclude their structural failure due to seismic load-ing which could cause loss of function to safety-related systems or components, in compliance with
- 10CFR50, General Design Criterion 3, Fire Protection.
Safety. Design Basis Four American Nuclear Insurer's (ANI) recommendations shall be followed such that fire hazards and potentials are reduced during construction of multiple unit plants when one or more units are in operation.
Safety Design Basis Five Structures,
- systems, and components important to safety shall be designed and located to minimize the fire hazards consistent with other plant safety requirements.
This requirement is in compliance with 10CFR50 General Design Criterion 3, Fire Protection.
Non-combustible-and heat resistant materials shall be used wherever practicable throughout the plant.
The basic fire protection for engineered safety fea-tures (ESF) shall be achieved through separation of systems serving the same safety function or by fire barriers between such installations.
Plant fire
- barriers, walls, and enclosures shall be rated and located as set forth in the PVNGS FPE.
