June 6, 1997, with Units 1 and 2 operating at 100% power, a fire detection alarm panel became inoperable. As required by Technical* Specification 3.21.B.1, a fire watch patrol was established within onehour. TS 3.21.B.1 also requires a fire watch inspection frequency of the affected fire areas "at least once per hour." The required fire area inspections were performed, i however the at-least-once-per-hour frequency was exceeded by one to seven minutes for some fire area patrols. The tardy fire watch patrols were performed by one individual. A fire did not occur, and there were no safety implications or consequences as a result of this event.

A Category 2 Root Cause Evaluation (RCE) is being conducted to determine the cause of this event and recommend corrective actions. This report is being made pursuant to 10CFR50. 73(a)(2)(i)(B) and will be supplemented upon completion of the RCE.

1.0 DESCRIPTION

OF THE EVENT On February 12, 1998, during Fire Protection Audit 98-02 being conducted by the Nuclear Oversight Department, .a situation that occurred on June 6, 1997 was identified where a .

Technical Specification (TS) fire watch exceeded the required inspection frequency.

On June 6, 1997, with Units 1 and 2 operating at 100% power, a fire detection alarm panel was declared inoperable at 0059 hours6.828704e-4 days <br />0.0164 hours <br />9.755291e-5 weeks <br />2.24495e-5 months <br />. As required by TS 3.21.8.1, a fire watch patrol was established within one hour and the TS action statement was exited at 0119 hours0.00138 days <br />0.0331 hours <br />1.967593e-4 weeks <br />4.52795e-5 months <br />.

TS 3.21.B.1 also requires a fire watch inspection frequency of the affected fire areas "at least once per hour." Based on log entries, the required fire area inspections were performed, however the at-least-once-per-hour frequency was exceeded by one to seven minutes for some fire area patrols. The tardy fire watch patrols were performed by one individual.

This report is being made pursuant to 10CFR50.73(a)(2)(i)(B) as a condition prohibited by Technical Specifications*. *** *** ** **

2.0 SIGNIFICANT SAFETY CONSEQUENCES AND IMPLICATIONS The required fire watches were initiated within the TS-required time period of one hour.

The affected fire areas requiring inspection were inspected, and the required number of inspections were performed. The personnel performing the fire watches were fire watch qualified to detect, report, and extinguish fires. Fire suppression equipment remained operable throughout the time frame.

If a fire had occurred, it would have been detected, reported, and extinguished. However, a fire did not occur. Therefore, this event resulted in no significant safety consequences or implications, and the health and safety of the public were not affected.

3.0 CAUSE A Category 2 Root Cause Evaluation (RCE) is being conducted to determine the cause of this event. Upon completion of the RCE, a supplement to this Licensee Event Report (LER) will be submitted. The LER supplement will include discussion of the cause of this event.

4.0 IMMEDIATE CORRECTIVE ACTION(S)

When Nuclear Oversight discovered that the required fire watch inspection frequency of "at least once per hour" had been exceeded, a station deviation was issued.
