Subject:
Waterford 3 SES Docket No. 50-382 License No. NPF-38 Waterford 3 Response to Generic Letter 89-10
" Safety-Related Motor-Operated Valve Testing and Surveillance" Gentlemen:
The purpose of this letter is to notify the NRC of the completion of the actions described in Generic Letter 89-10 as required by item m of the Generic Letter.
The NRC on June 28, 1989 promulgated Generic La.itter 89-10 and thereafter Supplements 1 through 6.
Entergy Operations Inc., Waterford 3, in response to Generic Letter 89-10 developed the Waterford 3 GL 89-10 M0V Program.
The program has been comprehensive, of long duration, and has required significant involvement from Waterford 3 personnel crossing multiple departments and engineering disciplines.
i The initial phases of the Waterford 3 GL 89-10 MOV Program were completed on June 28, 1994 and the following two items are open and are being addressed by Waterford 3: 1) the long-term resolution for MOVs identified as being potentially susceptible to pressure locking or thermal binding, and 2) justification of the use of static testing for periodic i
verification.

Waterford 3 Response to Generic letter 89-10, " Safety-r. elated Motor Operated Valve Testing and Surveillance" W3F1-94-0125 Page 2 July 28, 1994 No further actions subsequent to the Phase 2 inspection has been taken on pressure locking and thermal binding.
Waterford 3 final actions on pressure locking and thermal binding need to take into account the information contained in a separate NRC Generic Letter on the subject which is currently pending issuance.
Periodic verification, which will commen e at Waterford 3 no earlier than Refuel 7, is currently limited to static testing with diagnostics.
Justification for the use of static testing for periodic verification is currently under development. However, Waterford 3 is considering a number of possibilities which could affect the periodic verification program prior to its implementation. Waterford 3 will provide the NRC with a description of the periodic verification method and the justification for the use of that method prior to its implementation.
Although the initial phases of the program are complete, the long-term maintenance and periodic verification activities will continue.
Please contact me or Robert J. Murillo (504) 739-6715 should there be any questions regarding this letter.
Very truly yours, R.F. Burski Director Nuclear Safety RFB/RJM/tmm cc:
