~

a.

The fire detection system components for each area listed in Table 15.3.14-1 shall be operable, b.

c.

Area control panels for the areas listed in Table 15.3.14-1 may be inoperable provided:

(1) Within one hour of determining that the area control panel is inoperable, the affected area is inspected to assure that potential fire hazards are minimized; (2) Activity in the affected area is restricted to that which is necessary for continued operation; (3) A fire watch inspection is performed in the affected area twice per 8-hour shift.

d.

For each area listed in Table 15.3.14-1 which is not protected by a Halon gaseous suppression system:

(1) A single detection device may be inoperable.

(2) As long as at least 75% of an area's detection devices remain operable, multiple non-adjacent detection devices may be-inoperable.

15.3.14-3

(3) More than 25% of an area's detection devices or multiple adjacent detection devices may be inoperable provided that:

(a) Within one hour of determing that the detection devices are inoperable, the affected area is inspected to assure that potential fire hazards are minimized; (b) Activity in the affected area is restricted to that which-is necessary for continued operation; (c) A fire watch inspection is performed in the affected area twice per 8-hour shift.

e.

For each area listed in Table 15.3.14-1 which is protected by Halon gaseous suppression system, any number of detection device (s) may be inoperable provided that:

l (1) Within one hour of determining that the detection device (s) are inoperable the affected area is inspected to assure that potential-fire hazards are minimized:

(2) Activity in the affected area is restricted to that which is necesary for continued operation; I

(3) A fire watch inspection is performed in the affected area twice per 8-hour shift.

C.

Fire Barriers 1.

Fire Barrier Penetration Seals All fire barrier penetration seals protecting safety-related f

a.

i dreas shall be operable.

b.

A fire barrier penetration seal may be inoperable provided that:

l (1) Within one hour of. determining that the fire barrier pene--

tration seal is inoperable, the immediate area on each side-

/

of the fire barrier is inspected to assure that potential fire hazards are minimized; 15.3.14-4

^

..\\

i (2) Activity in th'e immediate area on each side of the fire barrier is restricted to that which is necessary:

(a) for continued operation; (b) to enable restoration of penetration seal operability.

(3) A fire watch inspection shall be performed on each side of the fire barrier twice per 8-hour shift.

Basis The overall fire protection program at Point Beach Nuclear Plant utilizes the principles of defense in depth.

This includes early warning fire detection and redundant fire suppression capability.

Collectively these measures ensure equipment operability, provide adequate capability to prevent and minimize damage to safety-related equipment, and allow safe plant shutdown in the event of a fire occurrence.

Should a portion or component of the fire protection system be inoperable, these specifications provide assurance that redundant methods of fire protection are 'readily available and that the capability to mitigate the consequences of a fire is maintained.

However, the system compon-ents are required to perform as designed in the event of a fire emergency.

The National Fire Protection Association and the plant insurance carrier have speci-fied periodic tests and inspections to demonstrate fire protection equipment operability.

The listed tests and inspection are based upon the requirements of these organizations.

Testing more frequently than that listed is not considered necessary to ensure operability and performance.
