Dear Mr. Denton:
In the Matter of the
)
Docket Nos. 50-259 Tennessee Valley Authority
)
50-260 50 296 This is in response to the letter from T. M. Novak to H. G. Parris dated March.16, 1981, concerning potential equipment deficiencies for Browns Ferry Nuclear Plant identifiad as a result of the NFC staff's preliminary reviaw of our submittals over the past months. The letter required that TVA provide a written statement supporting the safe operation of Brovns Ferry that takes into account the NRC staff's preliminary list of deficiencies indicated in Appendix B of the letter.
It appears that Appendix B of the March 16 letter is based on your review of my October 31, 1980, submittal since'it addresses the majority of the equipment listed in-table 5.2 of that submittal (Summary of Equipment Quali.'ication Status). Our October 31, 1980, 20-volume response serves as a reference document.
It contains the conditions for qualification and references all documentation of equipment status and qualification.
This will be maintained current, auditable, and available for review.
The classification and qualification of Class IE electrical equipment is a dynamic process which of necessity requires revision to the original submittal.
Revision 1 to our original response to-IE Bulletin 79-01B and the Qualification Program Plan, prepared under contract by Wyle Laboratories, were submitted with my Ma.ch 3, 1981, letter to J. P. C'Reilly. This revision is indicative of the evolutionary process.
We continue to focus our attention on equipment qualification and its impact on the safe operatien of Browns Ferry. We believe that our internal procedures for addressing equipment qualification, coupled with the tasks being performed under contract. by organizations such as Wyle
. Laboratories, adequately address the potential equipmu.t deficienc!es indicated in Appendix B of the March 16 letter. Several-Licensee Event
. Reports (LER's) have been submitted on' equipment identified as being unqualified under the requirements of IE Bulletin 79-01B.
LER's will be submitted on any equipment so identified in the future.

.Mr. Harold R. Denton

s Based on the above, we believe continued safe operation of Browns Ferry A
Lis adequately ensured.
'iVA has made and will continue to make every reasonable effort to comply'
. with the requirements of IE Bulletin 79-01B. However, several conditions.
over which TVA has no control may preclude full implementation of these requirements by June 30, 1982.. These conditions are the delay of publication of. the NRC Safety Evaluation Report, originally due to be completed by February -1,1981, and' the inability of equipment vendors to provide equipment qualified to the pertinent. qualification standards in sufficient quantities to meet demand. Additionally, due"to the nuclear industry's -competitive demand for qualified equipment, the lead time between actually purchasing the equipment and delivery'of the equipment
- e for installation is expected to be significant.
