3) Verifying that the following diesel generator lockout features prevent diesel generator starting only when required:

a) Turning gear engaged, or b) Maintenance mode.

d. At least once per 10 years by performing tank wall thickness measurements.

Q- The resulting data shall be evaluated and any abnormal degradation will be justified or corrected. Any abnormal degradation will be documented in a report to the Commission.

REFERENCES:

1. Letter from NRC to Gary R. Peterson, Duke, Issuance of improved Technical l Specifications Amendments for Catawba, September 30,1998. l BASES:

The supplemental Testing Requirements for demonstrating the OPERABILITY of the diesel generators are in accordance with the recommendations of Regulatory .

Guide 1.108, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants", Revision 1, August 1977, Regulatory Guide 1.137, " Fuel-Oil Systems for Standby Diesel Generators", Revision 1, October 1979, and the NRC Staff Evaluation Report conceming the Reliability of Diesel Generators at Catawba, August 14,1984. If any other metallic structures (building, new or modified piping systems, conduits) are placed in the ground near the Fuel Oil Storage System or if the original system is modified, the adequacy and frequency of

. inspections for the Cathodic Protection System shall be reevaluated and adjusted, I

q as required.

TESTING REQUIREMENTS (con't)

O iii. At least once per 6 months by performance of a system flush of the outside distribution loop to verify no flow blockage by fully opening the hydraulically most remote hydrant, iv. At least once per 12 months by cycling each testable valve in the flow path through at least one complete cycle of full travel,

v. At least once per 18 months by verifying that each valve (manual, power-operated, or automatic) in the flow path which is inaccessible during plant operations is in its correct position, vi. At least once per 18 months by performing a system functional test which includes simulated automatic actuation of the system throughout its operating sequence, and:

1) Verifying that each pump develops at least 2500 gpm at a net pressure of 144 psig by testing at three points on the pump performance curve,

2) Cycling each valve in the flow path which is not testable during l plant operation through at least one complete cycle of full travel, O and G

3) Verifying that each fire suppression pump starts within 10 psig of l its intended starting pressure (A pump, primary sw!!ch-95 psig; B pump, primary switch -90 psig; and C pump, primary switch-85 psig).

vii. At least once per 3 years by performing a flow test of the system in accordance with Chapter 8, Section 16 of the Fire Protection Handbook,15th Edition, published by the National Fire Protection Association.

BASES (cont'd) semiannually to annually - as applicable. The frequency shall not be extended beyond annually (plus grace period).

e if the results demonstrates 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 qaarterly or - quarterly to monthly - as applicable. The valve position verification need not be conducted more often than monthly.

The main bank (9 cylinders) or the reserve bank (9 cylinders) provides a sufficient quantity of CO2 to totally flood any of the three CA pump pits with the required design concentration. Therefore, the high pressure CO2 system is operable with the system aligned to either the main or the resente bank of cylinders. The system is aligned to the main or reserve bank of cylinders by means of a local manual toggle switch.

In the event that portions of the Fire Suppression Systems are inoperable, alternate 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 altemate means of fire fighting than if Q the inoperable equipment is the primary means of fire suppression.

This Selected Licensee Commitment is part of the Catawba Fire Protection Program and therefore subject to the provisions of the Catawba Facility Operating License Conditions #6 for NPF-52 and #8 for NPF-35.
