On November 16, 1989, Waterford Steam Electric Station Unit 3 was in mode 3

)

preparing for startup from Refuel 3. At 1025 hours0.0119 days <br />0.285 hours <br />0.00169 weeks <br />3.900125e-4 months <br />,. Emergency Diesel Generator l (EDG) "A" (EIIS Identifier EK-DG) was declared inoperable because Essential *

' Services Chiller "A" (EIIS Identifier 101) had been declared inoperable. This -

i action was necessary because Chiller "A" provides cooling for the Component Cooling Water (CCW) Pump "A" (EIIS Identifier CC-P) Room Cooler (EIIS Identifier VF-CLR) and CCW Pump "A" provides cooling for EDG "A". At that time Technical Specification (TS) 3.8.1.1. action requirement b was entered which requires verifying offsite AC power availability. Waterford 3 satisfies this action requirement by performance of Surveillance Procedure OP-903-066, " Electrical Breaker Alignment Check," within one hour of declaring an EDG inoperable and l

cach eight hours thereafter. The first performance of OP-903-066 was completed at 1045 hours0.0121 days <br />0.29 hours <br />0.00173 weeks <br />3.976225e-4 months <br />. On November 17, 1989, at 0100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br />, it was discovered that the surveillance required by 1845 hours0.0214 days <br />0.513 hours <br />0.00305 weeks <br />7.020225e-4 months <br /> on the previous day had not been performed.

Failure to perform an action requirement is reportable as a condition prnhibited by TS.

The root cause of this event is personnel error. While performing the other procedures required for a normal plant-startup, this additional electrical.

surveillance procedure was not performed. To prevent recurrence the Operations Control Room Supervisor involved will be counselled concerning the missed surveillance and a copy of this report will be required reading for all current Senior Reactor Operator License holders. These actions will be completed by January 1, 1990. The Operations Department will review and evaluate the current procedure and methodology for ensuring compliance with irregular / infrequent

'g ..

Limiting Condition for Operation (LCO) action requirements. Applicable results will be used to enhance the process and minimize the potential for recurrence.

This will be completed by February 1, 1990.

The offsite AC electrical pcwer was verified available at 0120 hours0.00139 days <br />0.0333 hours <br />1.984127e-4 weeks <br />4.566e-5 months <br /> on November 17, 1989, and was known to be available throughout this event; j therefore, no threat to the health and safety of the public or plant personnel

! existed.

SIMILAR EVENTS There was a similar event reported as LER-88-021 in which, after declaring an EDG inoperable, the initial electrical lineup verification required within one-s hour was overlooked by control room personnel. As in this case, offsite

-electrical power was known to be available throughout the event; therefore, no threat to the health and safety of the public or plant staff existed.
