l 9.S.1 FIRE PROTECTION SYSTEM 9.5.1.1 General This section is a description of the Fire Protection Program of the l50 CPSES units 1 and 2.

The evaluation of fire hazards is included in lADV71 theCPSESFireProtectionReport(FPR)whichfollowstheformatofthel U.S. Nuclear Regulatory Commissions's "Supplementary Guidance on l

Information Needed for Fire Protection Program Evaluation" and the l50 supplementary criteria in their September 30, 1976, letter.

l The overall Fire Protection Program was developed utilizing the defense in depth concept.

This concept is a combination of:

1.

Preventing fires from starting 2.

Quickly detecting and suppressing fires that do occur to limit l66 the extent of damage l

l 3.

Designing plant safety systems so that a fire that becomes fully established and burns for a considerable time, in spite of the fire protection systems provided, will not prevent essential plant safety functions from being performed.

The FPR quantifies potential fire hazards throughout the plant in lADV71 terms of combustible heat release loading.

The Fire Protection and l

Detection Systems are designed based on this heat release loading and l66 onthenatureofthetransientandinsitucombustiblematerialinthel A sumary of this information is presented in tabular form in lADV71 area.

Fire area i

F The fire area is that section of a building or the plant that is j

separated from other areas of the plant by fire barriers with

{

l openings and penetrations protected by seals or closures having I

l a fire resistance rating equal to the rating assigned to the I

barrier.

The fire areas extend through more than one elevation where plant design requirements and low amounts of combustible i

A0v71 l

material in a specific area allow.

These areas are designated l

on FPR Figures.

2.

Fire Barriers i

50 l

Fire barriers are those components of construction (walls, l

floors, or protective coverings) that are rated by approved l

laboratories or are constructed in accordance with the l

requirements stated by authorities having jurisdiction in hours l

of resistance to fire and used to prevent Snread of fire.

Fire Hazards Analysis Evaluation lADV71 A Fire Hazard Analysis Evaluation is an assessment of the impact l ADV71 of a single fire hazard on redundant cor,iponents or systems used l

to provide fire safe shutdown functions for the plant.

A Fire l

Hazards Analysis Evaluation is performed by a Fire Protection l

Engir:eer and, if required a Systems Engineer.

The purpose of a l

Fira Hazards Analysis Evaluation is to demonstrate compliance l

with BTP APCSB 9.5-1 Appendix A based en the following l

considerations:

l

- potential transient and in situ combustible hazards are l66 considered.

l

- protection provided is commensurate with the hazards.

l66 the consequences of a fire on the plant's ability to safely l 66 shutdown are considered.

l The Fire Hazards Analysis Evaluation is written, organized lADV71 and maintained to facilitate review by a perscn who is not l

involved in the evaluation, j

The conclusions of the FHA Evaluations are summarized in lADV71 the rpplicable sections of the Fire Protection Report.

l 9.5.1.2.2 Assumptions The FHA Evaluation is based on the following assumptions:

l50 1.

Generally, the minimum fire barrier rating is three hours except l 65 for the barriers enclosing the stairwells and elevator shaf ts, l

which are r6ted at two hours, the cable tray / conduit fire l

barriers which are rated at 1-hour, and other special cases l

where a rating of less than three hours is adequate.

Enclosure to TXX-88418 CPSES/FSAR April 29. 1988 ADV71 Pade25 of een it is determined that a fire involving a fire safe shutdown l

component or system will not affect its redundant counterpart, l

the redundant system is assumed to operate without failures.

ADV71 l3.

The Maximum Permissible Fire loading for a fire zone assumes a l

fire borning in the area which follows the characteristics of l

the standard time-temperature curve, or as noted in the FPR, l

Reference [19].

65 l 4.

A fire involving a combustible loading, up to the Maximum l

Permissible Fire Loading for the fire zone, will be contained j

within the fire area by the passive and active / fire protection l

features (i.e. fire wall and sprinklers, etc.).

Furthermore, l

it is assumed that if any of these passive or active fire

\\

protection features is inoperable and the compensatory actions l

required by Technical Specifications have been implemented then l

an equivalent level of protection is provided.

65 l 9.5.1.2.3 Methodology 65 l In order to evaluate potential fire hazards, provide adequate fire f

l protection,ensureisolationoffiresafeshutdownsystemsfromthese l hazards, and prevent the release of radioactiva material to the l environment,thefollowingmethodofdesignandanalysishasbeen l formulated and implemented for the entire plant:

{

i 54 l1.

The plant is divided into separate fire areas using plant walls 65 l

and floors as barriers.

Due consideration as-shown below is

,l l

given to the separation of redundant fire safe shutdown j

l components from each other, from non-fire safe shutdown l

components and from major concentrations of combustible 66 l

materials.

Considerations were also given to other area l

characteristics such as electrical cable routing into and through the area, the ductwork supplying and exhausting the i

l area, access and egress routes for the area, and vent area for l

depressurization during a tornado, i

9.5-6 i

Enclosure to TXX-88418 April 29, 1988 CPSES/FSAR Page 6 of 48 8.

Fixed automatic water suppression systems will generally be installed in safety related plant areas where any of the following conditions exist:

1 a.

A high fire hazard exists i

65 l

b.

Redundant safe shutdown equipment or cabling outside the l

Containment Building is located in the same fire area and l

i; not separated by a three hour fire barrier.

l c.

There is a congestion of cabling.

ADV71 l

In areas where condition (a) and in areas where condition (b)

I described above exists, the type of protection that will be l

provided as a minimum will be a sprinkler system providing l

coverage adequate for the hazard in the area unless l

justification for deviations are provided per reference (19] and l

as described in 9.5.1.6.1.

The water spray design density will 65 l

be based on Section 9.5.1.6.1-E.3.c.

9.5.1.D.3.c, sprinkler systems will be provided for cabling to j

augment other fire protection teatures-in the area, i

l ADV71 l9.

Where redundant fire safe shutdown equipment cabling is located l

in the same fire area and is not separated by a three hour fire l

barrier or a horizontal distance of 20 feet with negligible

\\

intervening combustibles or fire hazard, one train of this l

cabling will be enclosed by a one-hour fire barrier (or radiant j

i energy shield inside containment) unless an alternate shutdown l

path is utilized or justification for deviations are provided l

per reference (19] except as described in Section 9.5.1.6.1.

Automatic Water Spray Systems-l66 When a fire is detected its location is annunciated on the local fire detection control panel and in the l

control' room.

The Fire Detection Local Control Panel, transmits a signal to open the proper deluge valve. A water-flow alarm sounds locally and in the control room indicating water flowing through the piping network.

The deluge valves operate l66-automatically as described above, or can be manually l

operated locally. Once actuated, deluge valves can l

only be reset manually.

Refueling and maintenance operations in containment may introduce additional hazards such as contamination control materials, decontamination supplies, wood planking, temporary wiring, welding and flame cutting (with portable compressed fuel gas supply).

Possible fires would not l

necessarily be in the vicinity of fixed detection and suppression systems.

Management procedures and controls necessary to assure adequate fire protection are discussed in Section 3a.
