Subject:

McGuire Nuclear Station, Units 1 and 2 Docket Nos. 50-369 and 50-370 Pump and Valve Inservice Testing Program Program Revleion 16 (Unit 1) and 12 (Unit 2)

{Rollef Request No. 91-01)

(TACS 61271/61272)

Gentlemen:

Please find enclosed (pursuant to 10CFR 50.4 and 50.55a(g)) for NRC staff use and review ten copies of Unit. 1 Revision 16 and Unit 2 Revision 12 of the McGuire Nuclear Station Pump and Valve (IWP/IWV)

Inservice Testing Program.

These revisions are the result of nrogram enhancements identified by McGuire Design Study 0106, recently issued Design Basis Documents, and the recently received Safety Evaluation Report (SER) of the IST program.

The changes to the valve portion are summarized on Attachment 1, and the pump portion on Attachment 2. Only the affected pages are attached.

The McGuire SER was based on Unit 1 Revision 14 and Unit 2 Revision 10 of the IST program. Unit 1 Revision 15 and Unit 2 Revision 11 were issued prior to receiving this SER, and the changes included in them are not recognized by the NRC. The attached revisions resubmit those changes previously identified in the last revision, as well as additional changes.

Since this revision includes additions and deletions which are outside .

the scope of Generic Lotter 89-04, Section D, it is requested that the NRC review this material and notify Duke Power Compn.ny by July 1, 1991 as to its acceptability.

If you have any questions regarding the enclosed material, please call L.J. Rudy at (704) 373-3413.

Very trul yours, R.s. \ ww M.S. Tuckman LJR/s Attachments / Enclosures

1 11ote: Revisions are for both Units unless indicated otherwise.

1. Table of Contents a) Added Airlock (I A) system b) Added Diesel Generator Cooling Water (KD) system l c) Added control Area Ventilation (VC) system - Unit 1 only d) Changed page numbers appropriately, l

2.Section II.2 Table of Abbreviations a) Added FS Tail Safe to Legend

3.Section II.3 Definitions a) Added railsafe (PS) and defined how failsafe testing will be conducted.

4. Section 11.4 Data Sh9ets a) All data shoets were revised to exclude stroke time requirements. " Rapid Acting" 2 second valves were identified in the remarks column of revision 15 & 11, but removed in revision 16 & 12.

b) Data sheet page numbers changed to reflect addition of IA,KD and VC systems in both units.

c) CA-0020AB, CA-0027A, CA-0032B Changed category to AC and added LT to test requirements. It was determined that leakage past these valves is critical because it would not be directed to the S/G's, d) CA-0161C, CA-0162C Deleted from the program because the valves were determined not to have a safety functior per Design Study MGDS-0106, e) CA-0165, C A-0166 Added MTC to valves. Design Study 0106 determined valves have a safety function to close.

Valves SM-0009AB, SM-0010AB, SM-0011 AB, SM-0012AB have timing methods that allow the valves to be timed quarterly.

l q) CS-VG1 tiew shutdown justification added because of adding VG-17, VG-18, VG 19 and VG-20 to the program identified by Design Basis document MCS-1578.VC-00-0001.
