10-11-82 Facility:

Salem Generating Station Unit 1 Public Service Electric & Gas Company Hancock's Bridge, New Jersey 08038 IDENTIFICATION OF OCCURRENCE:

Diesel Generator Area Low Pressure CO2 System Inoperable.

CONDITIONS PRIOR TO OCCURRENCE:

Mode 1 - RX Power 100 % - Unit Load 1150 MWe DESCRIPTION OF OCCUEEENCE:

At 0745 hours0.00862 days <br />0.207 hours <br />0.00123 weeks <br />2.834725e-4 months <br />, October 11, 1982, during routine operation, the Diesel Generator Area Low Pressure CO2 System automatic initiation feature was disabled and tagged out for planned maintenance. A continuous fire watch with backup fire suppression equipment was immediately established in the area.

The tagout was necessary to insure personnel safety during work in the diesel generator spaces.

With the feature inoperable, Technical Specification Action Statement 3.7.10.3a applied.

The CO2 system manual actuation capability remained operable throughout the occurrence.

APPARENT CAUSE OF OCCURRENCE:

As noted, entry into the action statement was for the purpose of insuring personnel safety during planned maintenance.

ANALYSIS OF OCCURRENCE:

j The operability of the fire suppression systems ensure that adequate fire suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety related l

equipment is located.

The collective capability of the fire suppression systems is adequate to minimize potential damage to safety i

related equipment and is a major element in the facility fire protection program.

LER 82-084/99X0 ANALYSIS Of_QCCURRERCE: (cont'd)

Action Statement 3.7.10.3a Requires:

With one or more of the above required low pressure CO2 systems inoperable, establish a continuous fire watch with backup fire suppression equipment for unprotected area (s) within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />; restore the inoperable system to operable status within 14 days or, in lieu of any other report required by Specification 6.9.1, prepare and submit a special report to the commission pursuant to specification 6.9.2 within the next 30 days outlining the action taken, the cause of the inoperability and the plans and schedule for restoring the system to operable status.

As noted, a continuous fire watch with backup fire equipment was established, in compliance with the action statement.

Since protection was maintained, the event involved no risk to the health and safety of the public.

Due to additional administrative and procedural controls imposed during planned maintenance, the occurrence did not constitute operation in a degraded mode in accordance with Technical Specification 6.9.1.9b.

On October 25, 1982, the 14 day time period specified in Action Statement 3.7.10.3a expired, and the event became reportable in accordance with Technical Specification 6.9.2f, Special Reports for Fire Suppression Systems.

CORRECTIVE ACTIDH:

Due to continuing work in the diesel generator area, the automatic CO2 actuation feature will be kept disabled until completion of the present Unit 1 refueling outage in December 1982.

The manual actuation capability will be maintained operable, and the fire watch and backup suppression equipment will be available until that time.
