Report Number: 82-053/03X-1 Report Date: 09-03-82 Occurrence Date: 07-31-82 Facility: Salem Generating Station, Unit 1 Public Service Electric & Gas Company Hancocks Bridge, New Jersey 08038 IDENTIFICATION OF OCCURRENCE:

No. 1C Diesel Generator - Inoperable.

This report was initiated by Incident Report 82-205.

1 CONDITIONS PRIOR TO OCCURRENCE:

Mode 1 - Rx Power 99% - Unit Load 1050 MWe.

DESCRIPTION OF OCCURRENCE:

At 0112 hours0.0013 days <br />0.0311 hours <br />1.851852e-4 weeks <br />4.2616e-5 months <br />, July 31, 1982, during routine surveillance, an operator discovered a leak from a flexible hose on the jacket cooling water system of No. 1C Diesel Generator.

The diesel was declared inoperable, and Technical Specifi-cation Action Statement 3.8.1.1.a was entered, retroactive to the time of discovery of the problem. Tags were immediately placed to prevent operation and possible damage of the diesel generator. Nos, lA~and 1B Diesel Generators and both offsite transmission circuits were operable throughout the occurrence.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

The fai]ure of the hose was due to deterioration of the rubber

wall material. The hose was originally installed with the l diesel; this is the first instance of such a failure. No other factors contributing to the failure were noted, and it was assumed that the natural end of the component life was involved.

I ANALYSIS OF OCCURRENCE:

The operability of the A.C. and D.C. power sources and associated distribution systems during operation ensures that sufficient power will be available to supply the safety related equipment l for safe shutdown and mitigation of accident conditions of the facility. The requirements are consistent with the initial condition assumptions of the accident analyses, and are based on maintaining a single supply with an assumed loss of offsite power and single failure of the other A.C. source. As noted, the redundant diesel generators were operable, and therefore no risk to the health or safety of the public was involved.

I i

.- LpR 82-053/03X-1 ANALYSIS OF OCCURRENCE: (continued)

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.

Action Statement 3.8.1.1.a requires:

With either an offsite circuit or diesel generator inoperable, demonstrate the operability of the remaining A.C. sources by meeting 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 following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

CORRECTIVE ACTION:

The required surveillances were satisfactorily performed within one hour and every 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> thereafter, in compliance with the action statement. The failed flexible hose was replaced, and Surveillance Procedure SP (O) 4. 8.1.1. 2.a satisfactorily completed. At 0130 hours0.0015 days <br />0.0361 hours <br />2.149471e-4 weeks <br />4.9465e-5 months <br />, August 1, 1982, No. 1C Diesel Generator was declared operable, and Action Statement 3.8.1.1.a was terminated. The diesel manufacturer was contacted with respect to the problem and new hoses will be in-stalled, as needed, on the diesel generators during periodic mainte-nance scheduled for the next refueling outage.
