FAILURE TO COMPLETE WEEKLY BATTERY SURVEILLANCE REQUIREMENTS WITHIN THE ALLOWED TECHNICAL SPECIFICATION INTERVAL DUE TO A SCHEDULING OVERSIGHT

~At~rac (Cont'd)

The root causes of this event were less than adequate Technical Specification surveillance tracking methods and personnel error. Further corrective actions include counseling of responsible Electrical Maintenance Shop personnel and Technical Specification Surveillance Program changes.

This event posed no threat to the health and safety of either the public or plant personnel.

P~ICh i Power Level - 1%

Plant Mode - 2 (Startup)

On June 19, 1993, at 0611 hours0.00707 days <br />0.17 hours <br />0.00101 weeks <br />2.324855e-4 months <br />, WNP-2 failed to comply with Technical Specification Surveillance Requirements 4.8.2.1.a and 4.0.2 for all safety-related batteries. Surveillance Procedure PPM 7.4.8.2.1.20, "Weekly Battery Testing," satisfies the surveillance requirements for all plant safety-related batteries. The procedure was not completed within the required seven day interval plus 1.75 days (25% maximum allowable extension per Surveillance Requirement 4.0.2).

Electrical Maintenance Shop personnel submitted the battery surveillance procedure to the Shift Manager for work authorization on June 19, 1993, shortly before 1700 hours0.0197 days <br />0.472 hours <br />0.00281 weeks <br />6.4685e-4 months <br />. During the routine work authorization review, it was identified that the procedure should have been scheduled for June 16, 1993, with a work start "Late Date" of June 17, 1993. The Shift Manager subsequently initiated actions to perform PPM 7.4.8.2.1.20 immediately and determine the last successful completion of the procedure. The battery surveillance procedure was successfully completed on June 19, 1993, at 1837 hours0.0213 days <br />0.51 hours <br />0.00304 weeks <br />6.989785e-4 months <br /> with no discrepancies.

Shortly thereafter, it was discovered that the previous successful completion was on June 10, 1993, at 1211 hours0.014 days <br />0.336 hours <br />0.002 weeks <br />4.607855e-4 months <br />. Thus, the surveillance procedure should have been completed no later than 0611 hours0.00707 days <br />0.17 hours <br />0.00101 weeks <br />2.324855e-4 months <br /> on June 19, 1993, for Surveillance Requirement 4.0.2 compliance. This resulted in all plant safety-related batteries being technically inoperable from 0611 hours0.00707 days <br />0.17 hours <br />0.00101 weeks <br />2.324855e-4 months <br /> to 1837 hours0.0213 days <br />0.51 hours <br />0.00304 weeks <br />6.989785e-4 months <br /> on June 19, 1993, a period of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and 26 minutes. The associated Technical Specification Action Statements were not entered as the surveillance procedure was in progress. Surveillance Requirement 4.0.3 permits an action requirement delay of up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to complete a delinquent surveillance.

1. This event is reportable pursuant to 10CFR50.73(a)(2)(i)(B) as "Any operation or condition prohibited by the plant's Technical Specifications...."
2. At the time of this event, the Electrical Shop was working from a "Plant Restart Punchlist" following completion of the R-8 Maintenance and Refueling Outage. The punchlist was being used to list and coordinate all work for plant restart. Because the shop was concentrating on restart activities, battery surveillance procedure PPM 7.4.8.1.2.20 was not transferred from the normal "Daily Work List" to the "Plant Restart Punchlist" due to a shop administrative oversight. The Scheduled Maintenance S'stem (SMS) card for the battery surveillance was issued to the Electrical Shop in a timely manner and was added to the shop's "Surveillance Procedure Tracking Board." However, the surveillance procedure was again not transferred to the "Plant Restart Punchlist," due to another shop administrative oversight. Since Electrical Shop work activities were being scheduled solely from the punchlist, the surveillance was inadvertently left off the June 16, 1993, shop work schedule.
3. Electrical Maintenance Shop personnel responsible for this event were counseled to prevent recurrence and to reemphasize the importance of Technical Specification compliance,
4. The Plant Manager subsequently communicated his expectations to his staff regarding personnel accountability for completing surveillances within their normal intervals.

B. ~R~~e The two root causes of this event were:

1. Less than adequate Technical Specification surveillance tracking and statusing methods by Electrical Maintenance Shop supervision.
2. The failure of Electrical Shop personnel to capture and transfer PPM 7.4.8.1.2.20 from the "Daily Work List" and "Surveillance Procedure Tracking Board" to the "Plant Restart Punchlist."

FAILURE TO COMPLETE WEEKLY BATTERY SURVEILLANCE REQUIREMENTS WITHIN THE ALLOWED TECHNICAL SPECIFICATION INTERVAL DUE TO A SCHEDULING OVERSIGHT her rrec ive Action

1. Administrative Procedure PPM 1.5.1, "Technical Specification Surveillance Program," will be revised by September 1, 1993, to further strengthen the surveillance program. In the interim, daily reports detailing those surveillances approaching their due date will be generated and provided to the Shift Managers and plant management.

~fi l1 The battery surveillance procedure PPM 7.4.8.2.1.20 was successfully completed on June 19, 1993, at 1837 hours0.0213 days <br />0.51 hours <br />0.00304 weeks <br />6.989785e-4 months <br /> with no discrepancies. The allowed surveillance interval of 8.75 days was exceeded by only 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and 26 minutes as the procedure had previously been completed on June 10, 1993, at 1211 hours0.014 days <br />0.336 hours <br />0.002 weeks <br />4.607855e-4 months <br />.

Since all of the batteries met the surveillance procedure acceptance criteria, they were capable of performing their design safety functions during the interval between surveillances. This includes the delinquent period. Thus, there was no safety significance associated with this event and it posed no threat to the health and safety of either the public or plant personnel.

imil r Even Other events reported since 1988 that are considered similar to this event are listed below. These events involved conditions where Technical Specification surveillances were not performed within the required interval due to the lack of procedural and programmatic controls, or due to personnel errors. Those events that resulted from procedural and programmatic deficiencies are being addressed in LER 93-010 through implementation of the Technical Specification Surveillance Improvement Project. The remaining events were the result of personnel errors. Plant management is concerned about the recurrence of personnel errors resulting in missed surveillances. As a result, the Plant Manager has sponsored cultural, accountability and additional programmatic changes to address this issue.
