Subject:
Oconee Nuclear-Station-Docket Nos.- 50-269, -270; -287 Generic Letter'87-02 Verification-of Seismic Adequacy of Mechanical and..
Electrical Equipment in Operating Reactors, Unresolved-Safety Issue (USI) A-46 By my letter dated October 7,1988, I 'had committed to a schedule l for the q
plant walkdown associated with the implementation of:USI A-46 at Oconee j
Nuclear. Station. This schedule was contingent upon'the schedule for completion of generic efforts submitted by the Seismic Qualification Utility Group (SQUG) in its October 9, 1987 letter.- The SQUG schedule.
provided for completion of the Generic Implementation Procedure (GIP)1 during the first quarter of 1989, followed by NRC review and issuance of a final SER in the second quarter of 1989, q
My current understanding is that the final SER for A-46 implementation j
will be delayed at least until the middle of calendar year 1990._ Based on-this, the anticipated walkdown of Oconee Nuclear Station associated _vith the resolution of A-46 must be deferred beyond the original schedule; Until the final SER has been issued, I cannot' commit to a~ firm' schedule for the walkdown and other activities requested by Generic Letter 87-02.
I Within 60 days following reciept of the final SER and resolution _of'all.
outstanding issues, I will submit our implementation; plan'and schedule.
I would also like to integrate the resolution of USI A-46 with the resolution of numerous other related -seismic issues (e.g., Eastern
. {
Seismicity, Seismic Margins, and Severe Accident Individual Plant External l
Event Evaluations).
In view of the uncertainties in the requirements and schedule for resolution of these related issues, I reserve the right'to i
revise the implementation schedule for USI A-46 at Oconee Nuclear Station
-I to integrate these potential future requirements into a single,
- j cost-effective program.
Very truly yours, dk NAM" 9004240415 900410
