DAY YEAR On January 6, 1995 at 1112 hours0.0129 days <br />0.309 hours <br />0.00184 weeks <br />4.23116e-4 months <br /> it was discovered that the Unit 2 fire detection monitor panel switch (EZIS/ZC-HS) had been placed in the "off" position during the performance of a surveillance.

Zn the "off" position, visual and audible alarms associated with the Unit 2 fire detection zones will not alarm in the Control Room.

Zt was determined that the switch had been in the "off" position for approximately three hours, during which time all Unit 2 fire detection was inoperable without the appropriate compensatory measures being taken.

On January 26, 1995 it was determined that this event was reportable under 10CFR50.73(a)

(2) (i) (B), as operation prohibited by Technical Specifications.

The event is attributed to personnel error.

The switch was left in the "off" position in violation of the procedure being used to perform the surveillance.

If a fire had occurred during the period when the fixe detection system was inoperable, a "Fire System Actuation" or "C02 Header Pressurized" alarm would still have annunciated in the Control Room for the areas provided with fire suppression capabilities, alerting the Control Room to a fire in the monitored areas.

Routine security patrols and operator tours were also ongoing for areas without a fire suppression system.

Zn addition, multiple Unit 2 fire detection zones were being toured as a result of other fire protection concerns.

Based on this, the event did not represent a significant safety hazard and at no time was the health of safety of the public placed in jeopardy.

Descri tion of Event On January 6, 1995 at approximately 0815 hours0.00943 days <br />0.226 hours <br />0.00135 weeks <br />3.101075e-4 months <br />, the Unit 2 fire detection monitor panel switch (EZZS)/IC-HS) was taken to the "off" position by a technician performing a routine surveillance.

The technician then left the Control Room without restoring the panel alarm function.

The panel switch was in the HoffA position for approximately 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> before it was discovered at 1112 hours0.0129 days <br />0.309 hours <br />0.00184 weeks <br />4.23116e-4 months <br /> and restored to the "on" position.

The fire detection monitor panel switch (EZIS/ZC-HS) is a cut-out switch for the Pyrotronics fire detection system installed throughout the unit and in various site office buildings.

Zn the "off" position, visual and audible alarms associated.with the fire detection zones will not alarm in the Control Room.

During the 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> that the switch was in the AoffA position no visual or audible alarms could be received in the Control Room, causing the fire detection system to be inoperable without proper compensatory measures being taken.

Cause of Event

This event is attributed to personnel error.

The procedure for the surveillance being performed,

    • 12 THP 6030. IMP.153, allows the monitor panel switch (EIZS/IC-HS) to be taken to the HoffA position momentarily to reset alarms at the panel.

However, the procedure also specifically states that the technician at the panel is responsible for ensuring that the Control Room alarm functions are restored prior to leaving the test panel unattended.

The technician placed the switch in the AoffA position and then exitect the Control Room.

A lack of understanding of the function of the switch contributed to this event.

It was not understood until after the event, while reviewing the applicable print, that placing the switch to AoffA would defeat all Unit 2 fire detection.

al sis of Event This event was determined to be reportable on January 26, 1995 pursuant to aOCFR50.73(a)(2)(i)(B) as operation prohibited by the plant's Technical Specification.

Technical Specification 3.3.3.8 requires that within one hour, an hourly fire watch patrol be established if more than one half. of the fire detectors in any fire detection zones are inoperable.

With the fire detection monitor alarm switch in the "off" position, all Unit 2 fire detection was inoperable.

3 Anal sis of Event continued In the event of a fire, a "Fire System Actuation

" or

.RC02 Header Pressurized" alarm would still have annunciated in the Control Room for those areas provided with fire suppression capabilities.

Routine security patrols and operator tours were ongoing in the areas'onitored by the fire detection system but not having fire suppression capabilities.

In addition, multiple Un't 2 fire detection zones were being toured in support of other fire protection concerns.

Based on this, the event did not represent a significant safety concern.

At no time was the health or safety of the public jeopardized.

Corrective Action

Upon discovery, the switch was restored to the "on" position and testing was completed.

To prevent recurrence, labels have been placed on the control panel for each unit at the monitor switch.

The label cautions personnel against leaving the switch in the "off"position and states the results of leaving it in. that configuration, including the Technical Specification which must be entered.
