Generic Letter 88-17 and NUREG 1410 involve concems associated with a loss of Residual Heat Removal during NC System reduced inventory. Numerous events have occurred in the industry that resulted in a loss of residual heat removal during reduced inventory cperation. This is of great concem due to the potential for substantial core damage occurring in a relatively short time period. This Selected Licensee Commitment depicts those commitments which are extremely important to nuclear safety, however, are not present!y covered by Technical Specifications.

I- The OPERABILITY of the Fire Suppression Systems ensures that adequate fire suppression capability is available to confine and extinguish fires occurring in
! any portion of the facility where safety-related equipment is located. The Fire ;
Suppression System consists of the water system, spray, and/or sprinklers, 1 CO2, and fire hose stations. The collective capability of the Fire Suppression j
,- Systems is adequate to minimize potential damage to safety-related equipment j l and is a major element in the facility Fire Protection Program.
The proper positioning of RF/RY valves is critical to delivering fire suppression water at the fire source as quickly as possible. The option of increasing or decreasing the frequency of valve position verification allows the ability to optimize plant operational resources. Should an adverse trend develop with RF/RY valve positions, the frequency of verification shall be increased. Similarly
, if the RF/RY valve position trends are positive, the frequency of verification could be decreased. Througn programmed trending of RF/RY as found valve positions,
! the RF/RY System will be maintained at predetemJned reliability standards. The RF/RY System Engineer is responsible for trending and determining verification
- frequencies based on the following: .
s initially the frequency will be monthly.
t I L
Chapter 16.9.1 Page 3 of 4 03/18/97
I Annually review the results of the completed valve position verification procedures.
- If the results demonstrate that the valves are found in the correct position at least 99% of the time, the frequency of conducting the valve position verification may be decreased from - monthly to quarterly or - quarterly to ,
semlannually or - semiannually to annually - as applicable. The frequency shall not be extended beyond annually (p!us grace period).
2 If the results demonstrate that the valves are not found in the correct position at least 99% of the time, the frequency of conducting the valve position :
verification shall be increased from - annually to semiannually or -
semiannually to quarterly or - quarterly to monthly - as applicable. The valve position verification need not be conducted more often that monthly.
In the event that portions of the Fire Suppression Systems are inoperable, ditemate backup fire-fighting equipment is required to be made available in the affected areas until the inoperable equipment is restored to service. When the inoperable fire-fighting equipment is intended for use as a backup means of fire suppression, a longer period of time is allowed to provide an attemate means of p fire fighting than if the inoperable equipment is the primary means of fire !
d suppression.
In the event the Fire Suppression Water System becomes inoperable, immediate !
i corrective measures must be taken since this system provides the major fire suppression capability of the plant.
This Selected Licensee Commitment is part of the Catawba Fire Protection
, Program and themfore subject to the provisions of the Catawba Facility g Operating License Conditions #6 for NPF-52 and #8 for NPF-35.

4 BASES:
I The functional integrity of the fire barrier and associated penetration seals ,
ensures that fires will be confined or adequatoly retarded so that the following ;
- criteria is achieved
- Fire will not spread from non-safety related areas to safety related areas, e Fire will not damage redundant analyzed post Fire Safe Shutdown equipment, i e Fire will not spread from the balance of plant to the control complex, ,
e Fire will not spread from non-containment areas to containment areas. i The fire barriers and associated penetration seals are passive elements in the facility fire protection program and are subject to periodic inspections.
Fire barriers penetration seals, including cable / pipe penetration seals, fire doors, i and fire dampers, are considered functional when the visually observed condition ;
indicates no abnormal change in appearance or abnormal degradation. An ;
evaluation is performed to determine the cause of any identified fire barrier penetration seal abnormal change in appearance or abnormal degradation and the affect of this change on the ability of the fire barrier penetration seal to ;
perform its function. Based on this evaluation additional inspections may be performed.
During periods of time when a barrier is not functional, either:
(1) a continuous fire watch is required to be maintained in the vicinity of the affected barrier, or (2) the fire detectors on at least one side of the affected barrier must be verified OPERABLE and an hourly fire watch patrol established, until the barrier is restored to functional status.
