I Table 3.3.7.9-1 of Technical Specification 3.3.7.9 requires a minimum number of fire detection instruments to remain operable. On March 27,1995, at 1545 hours0.0179 days <br />0.429 hours <br />0.00255 weeks <br />5.878725e-4 months <br />, the minimum number of required operable detectors for Fire Detection Zone 2-32 had not been maintained, thereby exceeding the 14-day timeclock allowed by the Technical Specification. This Fire Detection Zone is located in the Unit 2 Reactor Building at elevation 694'-6", Fire Hazard Zones 3H1,3H2, and 3H3.
Fire Detection Zone 2-32 was taken out of service to prevent spurious alarms caused by work activities (i.e., welding, cutting, and grinding) being performed in the area during the current Unit 2 Refueling Outage. Per the Action Statement requirements of Technical Specification 3.3.7.9, a Fire Watch was established to inspect the affected fire detection zone once every hour while the detectors are inoperable. Detection Zone 2-32 will be reNmed to service upon completion of the work activities associated with the Unit 2 Refueling Outage.
l This Special Report is required since the detectors were not restored to an operable status within 14 days.
j Sincerely.
