Subject:
McGuire Nuclear Station,' Units 1 and 2' Docket Nos. 50-369 and 50-370
-Pump-and Valve Inservice Testing Program NRC Review / Program Revision 14i(Unit 1) and 10'(Unit 2)
[ Relief Request No.=90-01)
(TACS 61271/61272)-
Gentlement The NRC staff (with technical assistance from a contracted reviewer, EG&G Idaho, Inc.) is currently in the process of reviewing the McGuire Nuclenr:
r Station 10 CFR 50.55a(g) Pump and Valve Inservice Testing (IST) Program for the initial 120 month (10 year) inspection interval. The proposed-plan / schedule for this review / approval was discussed in my May~6, 19i58 Unit-1 Revision 10/ Unit 2 Revision 6 program submittal. While:the NRC has not yet approved the McGuire IST Program,' issuance of,a Safety: Evaluation Report (SER) is imminent (as indicated in NRC Generic Letter No.'89-04'and'ini recent discussions with the NRC McGuire Project Manager).
Please find enclosed (pursuant to 10 CFR 50.4 and 50.55a(g)) for NRC staff use and review 10 copies of Unit 1 Revision 14 and Unit.2 Revision 10 ofithe McGuire Nuclear Station Pump and Valve.(IWP/IW) inservice Testing Program..
These revisions are based on discussions with the NRC (and EG&G) on March 5, 27, and April 3, 1990, during which the NRC requested certain revisions in order that the SER could adequately be completed. Additional valve. testing (IW) revisions convert some of the relief requests to cold shutdown justifications, and are the result of enhanced test procedures. Note that valve 1ML-466 is being deleted during the current McGuire Unit l' refueling outage rather than in a future outage as indicated to the NRC'in the April 3rd telecon, and therefore this valve is being deleted from the IW Program in this revision (this is contrary to what had been discussed with the NRC; i.e. that we would revise its relief request until the valve could'be deleted).
A description (and justification / basis where not obvious or self-explanatory or an administrative type change, etc.) of the specific changes made is ' contained in Attachments 1 (IWP Changes) and 2 (IW changes) for Units 1 and 2.
These rnvinions comply with the guidance provided in.

U. S., Nuclear Regulatory Commission April 20, 1990 Page 2 Generic Letter 89-04 for making modifications to IST Programs. These revisions should be incorporated into your Units 1 and 2 pump and valve Inservice Testing Program manual, removing any superseded pages of-the program. Duke Power Company. intends to implement the Units'I and 2 program as revised on an interim basis pending program approval by the NRC. Note that some of these revisions will not be implemented until a future date, as specified in the revisions themselves (e.g. Relief Request I.A.C-(Unit.1) and I.4.B (Unit 2)),
Please note that since this submittal provides material to be incorporated into our previously transmitted IWP/IWV Pump and Valve-Inservice Testing Program (originally submitted for NRC review and approval on November 14, 1978 (Unit 1) and March 31, 1983 (Unit 2)) which is still currently under review and has not yet roccived formal NRC approval, no additional fees pursuant to 10 CFR 170 are applicable (the IST Program is part of the-operating license application and fee for its review / approval should'be covered by the fee for the operating license applications for McGuire Nuclear Station Units 1 and 2).
Once the IST Program has received final NRC approval any subsequent. revisions would then be subject to approval fees-in accordanco with the provisions of 10 CFR 170.
If additional information is needed regarding the basis for any of-the:
enclosed revisions (especially with respect to any impacts on-the McGuire IST Program SER which is currently being written).or if Duke can otherwise aid in the IST review / approval process, please contact Mr.-P..B.'Nardoci at (704) 373-7432.
