DESCRIPTION OF OCCURRENCE:

At 0230 hours0.00266 days <br />0.0639 hours <br />3.80291e-4 weeks <br />8.7515e-5 months <br />, September 28, 1982, during the performance of Surveillance Procedure SP (O) 4. 8.1.1.2, an operator discovered-service water leakage emanating from theLpiping-on No. 2A Emergency Diesel Generator oil cooler. The diesel was declared inoperable and Technical Specification Action Statement 3.8.1.1.b was entered.

Operability of the redundant AC power' sources was demonstrated by satisfactorily performing surveillance as required by tha Technical Specifications.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

The leakage was. emanating from a hole in a pipe' cap. The L failure of the cap apparently involved accelerated erosion I resulting from silt in the service water. No previous problems of this type have been noted, and the occurrence was assumed to be of an isolated nature.

ANALYSIS OF OCCURRENCE:

The operability of AC power sources ensures that power-will be available to supply safety related equipment required for safe shutdown of the~ facility and mitigation of accidents considered in the FSAR. As noted, redundant AC power sources were operable, and the incident involved no risk-to the health or safety of the public. The occurrence constituted operation in a degraded mode permitted by a limiting condition for operation and is reportable in accordance with Technical Specification 6.9.1.9.b.

, ..LER 82-ll5/03L ANALYSIS OF OCCURRENCE: (continued)

Action Statement 3.8.1.1.a requires:

With either an AC offsite source to the vital bus system or diesel generator inoperable, demonstrate the operability of the remaining AC sources by performing Surveillance Requirements 4.8.1.1.1.a and 4.8.1.1.2.a.2 within one hour and at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> thereafter; restore at least two offsite circuits and three diesel generators to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in at least hot standby within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in cold shutdown within the fvllowing 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

CORRECTCVE ACTION:

As notel, the surveillances of redundant power sources were.

performed, in compliance with the action statement. The failed pipe cap was replaced, the leakage was eliminated, and the diesel was satisfactorily tested. No. 2A Emergency Diesel Generator was declared operable at 0610 hours0.00706 days <br />0.169 hours <br />0.00101 weeks <br />2.32105e-4 months <br />, September 28, 1982, and Action Statement 3.8.1.1.b was terminated.
