Subject:
McGuire Nuclear Station,' Units 1 and 2 Docket Nos. 50-369 and 50-370 IWP/IWV Pump and. Valve' Inservice Testing Program
- NRC Review / Program Revision
[ Relief. Request No. 89-03}
(TACS 61271/61272)
Gentlemen:
-The'NRC Staff.(with technical' assistance from a contracted reviewer, EG&Gl Idaho,_
-Inc.) is currently in the process of reviewing the McGuire Nuclear Station 10 CFR 50.55a(g) Pump and Valve Inservice Testing (IST) Program for the initial 120 tmonth (10 year)~ inspection interval. The proposed plan / schedule for this' review / approval was discussed in my May 6, 1988 Unit 1 Revision 10/ Unit 2 Revision 6 program submittal,"with program' approval having been targeted for by.
the end of 1988.. However, to date, the NRC has not yet' approved the McGuire IST l
Program,.although. issuance'of a' Safety Evaluation Report (SER) is imminent (as
' indicated in NRC Generic Letter No. 89-04).
Please find enclose'd (pursuant to 10 CFR50.4 and 50.55a(g)) for NRC staff use and
. review 10 copies of Unit 1 Revision 12 and Unit 2 Revision 8 (both dated April 19, 1989) of the McGuire Nuclear Station Pump and Valve Inservice Testing Program. 'This revision corrects various typographical and other errors contained-in.the' October 31, 1988' Revision 11 (Unit 1)/7 (Unit 2) program submittal, along with recently identified program changes (e.g. with respect to Licensee Event Report 369/89-05 and Problem Identification Report 0-M89-0077). A description /
justification of-the specific changes made is contained in Attachments 1 (Unit 1) and 2 (Unit-2).- This revision complies with the guidance provided in Generic Letter 89-04 for making modifications to IST Programs. These revisions should be incorporated into your Unit 1 and 2 Pump and Valve Inservice Testing Program Manual, removing any superseded pages of the program.
.It is my understanding that the upcoming NRC SER will require certain changes to the McGuire IST Program. Although the enclosed changes are not expected to be able to be reflectediin the SER, Duke did not consider it prudent to wait until receipt of'the SER and subsequent Duke review / evaluation before making the enclosed program changes (along with any others that may be required by the SER).
~
This' matter has been discussed with Mr. D. S. Hood (NRC/0NRR). Duke Power Company intends to implement the Unit 1 and 2 program as revised on an interim basis
-pending program approval by.the NRC.
If additional ~information is needed regarding the basis for any of the enclosed revisions or if Duke can othetvise aid in the IST review / approval process, please
. advise.

7 U. S. Nuclear Regulatory Commission Page Two April 19, 1989 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 received formal NRC approval, no additional fees pursuant to 10CFR 170 are applicabic (the IWP/IWV 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 IWP/IWV program has received final NRC approval any subsequent revisions would then be subject to amendment fees in accordance with the provisions of 10CFR 170.

UNIT 1 IWV/IWP REVISION 12 Paga 1 1.
Table of Contents Minor changes were made in the 7
format.
2.
Sect.
I.1:
A note was added in this section to identify a deficiency with test acceptance criteria for Diesel Generator Sump pumps.
3.
Sect.
I.4B:
The Acceptance' Criteria for flowrate in Table IWP-3100-2 was modified for our Fuel Oil Transfer Pumps.
This will prevent level instrumentation fluctuations from sending these pumps into the IWP(1980) High Alert and Required Action ranges.
The Fuel Oil Transfer Pumps are designed to produce a flowrate of 22 gpm.
The system design flowrate requirement is 11 gpm.
This difference provides a comfortable margin in the event a reference value is falsely established.
Using criteria in the attached relief request, a false reference value could only allow 12% pump degradation before requiring any action in accordance with IWP.
4.
Sect. I.4F:
The D/G Sump Pump run time of approximately 60 seconds was added.
i This was added to point out the IWP stabilization period of 5 minutes can not be met with our present system configuration.
However, our test procedure simulates emergency design conditions and verifies the pumps will provide.their intended safety function.
5.
Sect. II.3:
The definition of RF was changed to include Modes 3,4 and 5.
6.
Sect. II.4:
a)
The format of the data sheets was changed to include system name and a column for revision number.
