l 1. Fire Barrier Penetration Seals l l

l

a. All fire barrier penetration seals protecting safety-related areas shall be operable.
b. A fire barrier penetration seal may be inoperable provided that:  :

(1) Within one hour of determining that the fire barrier penetra-tion seal is inoperable, the immediate area on each side of the fire barrier is inspected to assure that potential fire hazards are minimized; (2) Activity in the immediate area on each side of the fire barrier is restricted to that which is necessary:

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

Specification 15.6.9.2.F. ,

, B_a't.s 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 l protection are readily available and that the capability to mitigate the con-j sequences of a fire is maintained.

~

Fire Protection Association and the plant insurance carrier have specified periodic tests and inspections to demonstrate fire protection' equipment oper- .1 ability. 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.  !

D. Failure of Containment High-Range Radiation Monitor A minimum of two in-containment radiation-level monitors with a maximum range of 810 rad /hr (10 7

/hr for photons only) should be operable at all times except for cold shutdown and refueling outages. This is specified in Table-15.3.5-5, item 7. If the minimum number of operable channels are not restored to operable condition within seven days after failure, a special report shall be submitted to the NRC within thirty days following the event outlining the action taken,.the cause of the inoperability and the plans and schedule for restoring the system to operable status.

E. Failure of Main Steam Line Radiation Monitors If a main steam line radiation monitor (SA-11) fails and cannot be restored to operability in seven days, prepare a special report within thirty days of the event, outlining the action taken, the cause of the inoperability and the plans and schedule for restoring the channel to operable status.

F. Fire Protection System Degradation Degradation of fire protection systems or components as described in Specification 15.3.14 which render the system inoperable shall be the subject of a special report, prepared and submitted within 30 days.

The report will outline the action taken, the cause of the inoperability, dnd the plans and schedule for restoring the system to o,'erable status.
