(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 determining 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 hourly.

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:

(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 necessary for continued operation; (3) A fire watch inspection is performed in the affected area hourly.

b. A fire barrier penetration seal may be inoperable provided that:

~

(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;,

(4) Activity in the 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 hourly.

(4) Restore the inoperable fire barrier to operable status within 7 days or, in lieu of any other report required by Specification 15.6.6 prepare and submit a special report pursuant to Specification 15.6.9.3.G.

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 15.3.14-5

t fire occurrence. Should a portion of couponent of the fire protection system be inoperable, these specifications provide assurance that redundant methods of fire protection are readily ...ilable and that the capability to mitigate the consequences of a fire is maintained.
