ENCLOSURE TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT UNITS 1, 2,
AND 3 REPLY TO NOTICE OF VIOLATION INSPECTION REPORT NUMBER 50-259, 260, 296/94-26 EFSTATEMENT OF THE VIOLATION "10 CFR PART 50 Appendix B, Criterion V instructions, Procedures and Drawings, as implemented by the TVA Nuclear Quality Assurance (NQA) Plan (TVA-NA-PLN89-A), Revision 3, requires that activities affecting quality shall be prescribed by documented procedures and activities shall be accomplished in accordance with these procedures.
Licensee procedure 0-SI-4.9A, Emergency Diesel Generator (EGD) reliability and Start Log, revision 3, required that an EDG reliability determination be calculated following an EDG failure.
Contrary to the above, on October 31, 1994 - November 4,
- 1994, one example was identified in which a reliability determination was not performed per procedure 0-SI-4.9.A for an EDG 3D failure which occurred on September 7, 1993.
This is a Severity Level IV Violation (Supplement I)."
TVA's Reply to the Violation 1.
Reason for the Violation This violation resulted from a failure to follow procedure concerning the requirements of Surveillance Instruction (SI) 0-SI-4.9.A,
" Diesel Generator Reliability And Start Log".
Specifically, during a review of the EDG reliability logs, TVA identified an instance where the Emergency Diesel Generator (EDG) Reliability Program Worksheet was not i
completed following a load run demand failure of EDG 3D on September 7, 1993.
An oversite on the part of the individual responsible for j
maintaining the reliability log at the time of the event led to this violation.
The individual, who is no longer l
employed by TVA, was contacted regarding the event. The individual indicated that he understood the requirements of i
the SI and that he thought the work sheet had been completed.
However, no documentation can be located to show that the action has been completed.

e 2.
Corrective Steps Taken And Results Achieved To document this noncompliance with the SI, a Problem l
Evaluation Report was initiated in accordance with TVA's Corrective Action Program.
A review of the previous valid EDG failures was performed to determine if other EDG failures had been properly documented on the EDG Reliability Program Worksheet.
This review did not identify any other examples where valid EDG failure was not properly documented.
Therefore, TVA considers this event co be isolated.
i The EDG Reliability Program Worksheet was completed for the l
September 7, 1993 load run demand failure.
The worksheet results indicated that the EDG reliability is above the l
established target value of 0.95.
As previously stated, the individual involved in the event leading to this NOV is no longer employed by TVA.
- However, this event and the reasons for the violation have been discussed with the individual who is currently responsible for the EDG Reliability Program.
3.
Corrective Stoos That Ihave been orl Will be Taken to Prevent Recurrence i
No further corrective actions are believed necessary.
4.
Date When Full Compliance Will be Achieved With respect to the matter identified above, TVA is presently in full compliance.
