Subject:

McGuire Nuclear Station, Units 1 and 2 Docket Nos. 50-369 and 50-370 IWP/IWV Pump and Valve Inservice Testing Program Revision

Dear Mr. Denton:

Pursuant to 10 CFR 50.55a(g), enclosed for NRC staff use and review are ten copies of Unit 1 Revision 9 and Unit 2 Revision 5 (both dated April 1, 1986) to the McGuire Nuclear Station Pump and Valve Inservice Testing Program. These revisions correct miscellaneous / typographical omissions / errors, provide further clarification for certain relief requests, incorporate additional requests for relief from code requirements, reflect changes or modifications to various alternate testing methods, reflect changes in valve-nomenclature, and add / delete valves from the program. Justification for the revisions is as follows:

Pump Inservice Testing Program o No changes.

Valve Inservice Testing Program e Addition / deletion / correction of train designation in valve numbers due to their being inadvertently omitted or typographical errors from previous revision. [ Unit 1 only: Pages II.6-2, II.6-3, II.6-4, II.9-2, II.9-5, II.34-2, II.35-6, II.35-11, and II.35-12. Units 1 and 2: Pages II.6-5, II.6-7, II.6-9, II.15-2, II.21-2, II.21-3, II.21-4, II.31-9, II.32-7, 11.34-4, II.34-6, and II.35-30. Unit 2 only: Pages II.9-2a, II.35-5, and II.35-11]

4 e Clarification of when Auxiliary Feedwater (CA) System check valves CA-61, 53, 45, 37, 65, 57, 49, and 41 will be full stroked so the unit can proceed to Mode 2. In addition, correction of j typographical error (VALVE). [ Units 1 and 2: Page II.6-8] 1 8604150281 860401 PDR ADOCK 05000369 ,

P PDR e i en

Mr. Harold R. Denton April 1, 1986 Page 2 e Addition / deletion _of testing alternative abbreviation to correspond to the alternate testing specified on the valve relief requests due to their being inadvertently omitted or typographical errors from previous revisions. [ Unit 1 only: ,

Pages II.35-4 and II.35-5. Units 1 and 2: Pages II.9-2 and II.9-4. Unit 2 only: Pages II.35-3 and II.35-4]

e Submittal of relief request to change the testing requirements of Chemical and Volume Control (NV) System valve NV-22. This valve is in line with another valve (NV-21A) which cannot be cycled quarterly due to the possibility of a reactor low pressure trip.

The relief request is similar to the relief request for valve NV-21A. [ Units 1 and 2: Pages 11.9-2 and II.9-6c]

e Deletion of partial-stroke during cold shutdown provision from the alternate testing specified by the relief request for Chemical and Volume Control (NV) System valve NV-223. The same reasoning for not full-stroke exercising the valve during plant operation or cold shutdown also applies to the partial-stroke test. The relief is revised to require only full-stroke exercising during refueling. The basis for the relief is also revised accordingly to reflect this. (NOTE: This matter is discussed in NRC/0IE Inspection Report Nos. 50-369/85-40 and 50-370/85-41, and in Licensee Event Report (LER) 369/85-32).

[ Units 1 and 2: Pages II.9-4 and II.9-11]

e Modification of the alternate testing of the relief request for the Containment Purge Ventilation (VP) system valves to not require timing the valves after operation if the valves are operated in a mode where the containment timing technical specification (T.S. 3.6.1.9) does not apply and are returned to the closed position prior to a mode where the containment timing spec. applies. Experience shows that these valves must be leak tested every time they are cycled. To ensure containment integrity, these valves will not be cycle timed quarterly. These valves will remain in their safety position (closed) while in a mode that requires containment integrity and valve cycle timing. l

[ Units 1 and 2: Page II.13-5]

e Deletion of testing alternative abbreviation given for Nuclear Service Water (RN) system valves RN-79A and RN-80B due to typographical error. These valves are cycled quarterly. [ Units 1 and 2: Page II.15-2]

e Change to isolation time specified for Containment Ventilation i Cooling Water (RV) system valve RV-76A due to typographical  !

error. This valve has a cycle time of 1 60 seconds. [ Units 1 l and 2: Page II.15-2]

Mr. Harold R. Denton April 1, 1986 Page 3 o Deletion of valves 2RV-151A and 2RV-1528 from the Containment Ventilation Cooling Water (RV) system listing and addition of valves 2RN-299A and 2RN-2798 to the Nuclear Service Water (RN) system listing. The nomenclature of Unit 2 valves 2RV-151A and 2RV-152B were changed to 2RN-299A and 2RN-2798 respectively in order that they would correspond to their equivalent function Unit i valves (i.e. IRN-299A~and 1RN-2798). (NOTE: the relabeling of these valves was identified as a human engineering discrepancy (HED No. M-2-0330) in the Control Room Review Summary Report for McGuire Units 1 and 2 which was submitted pursuant to supplement I to NUREG-0737). In addition, the flow diagram listing for the Unit 2 Nuclear Service Water system section is revised to reflect the addition of these valves (with their attendant flow diagram) to the Unit 2 RN system listing. (Unit 2 only: Pages II.15-3, II.31-1, and 11.31-11]

e Correction of the drawing coordinates given for Feedwater (CF) system valves CF-153B and CF-155B due to typographical error.

[ Units 1 and 2: Page II.21-4]

e Correction of test requirements abbreviation for Liquid Waste Recycle (WL) system valve WL-385 to correspond to'the test requirement specified on the valve's relief request. The valve is incorrectly listed as requiring a CT test. WL-385 is a check valve and requires a MT. [ Units 1 and 2: Page II.25-3]

e Deletion of Nuclear Sampling (NM) system valves NM-67 and NM-68' ,

from program. Unit I valves INM-67 and INM-68 have a blank I flange installed upstream prohibiting flow (i.e. essentially-removed from the system) and therefore are passive; they have no safety significance and are not part of the pressure boundary and are therefore"now;similar to category "E". valves (which are not included in the IWP/IWV Program). Unit 2 valves 2NM-67 and i 2NM-68 have.been deleted from the Nuclear Sampling system (NOTE: '

The Unit i valves were not removed due to radiation levels).

[ Units 1 and'2: ' Pages 11.30-2 and II.30-3]

le Addition of Nuclear Sampl,ing (NM) system valves NM-420 and NM-421 to the program. These check'_ valves have-been added to the

- Nuclear Sampling system by a^recent~ modification and require leak testing.- [ Units 1 and 2: Page II.30-3]

e Deletion of valves IRN-299A, 1RN-279B, 1RN-64A, IRN-638, 1RN-269A, and IRN-297B from'the Unit 2 Nuclear Service Water (RN) system listing. These valves are included in the portion (i.e.

valves on drawing MC-1574-1.0).of the Unit.2 RN system listing intended to present for information only the valves that are covered by the Unit 1 inservice testing program but are shared by both units. The RN valves shared by both units are those with a "0" prefix on the valve number. These valves with.the "1" prefix

Mr. Harold R. Denton April 1, 1986 Page 4 are Unit 1 only valves and are not shared by both units (there are corresponding equivalent function Unit 2 valves). Conse-quently the Unit 2 RN system listing is revised to correctly show the valves that are actually shared by both units. Also, the note on the Unit 2 Nuclear Service Water system title page explaining the inclusion of the shared valves in the Unit 2 RN listing is revised to better reflect this distinction, and the corresponding relief request for Unit I valves 1RN-64A and 1RN-63B which was presented as part of the shared valves infor-mation is also deleted. In addition, a redundant flow diagram number (MC-2574-1.1) is deleted from the Unit 2 RN System flow diagram listing. [ Unit 2 only: Pages II.31-1, 11.31-3, II.31-4, and II.31-12]

e Submittal of relief requests to reflect actual testing of Refueling Water (FW) system valve FW-28 and Residual Heat Removal (ND) system valves ND-23 and ND-8. These valves are partial stroked quarterly, but due to the capabilities of the Residual Heat Removal system these valves can only be full stroked during refueling. [ Units 1 and 2: Pages II.33-3, II.33-5, II.34-2, and II.34-8]

e Deletion of the partial-stroke quarterly provision from the alternate testing specified by the relief request for Unit 2 Residual Heat Removal (ND) system valve 2ND-70. The corresponding Unit i valve (IND-70) is partial stroked quarterly when ND Pump 1A is run in miniflow. However, the miniflow for ND Pump 2A does not pass through 2ND-70 so it cannot be " partial stroked quarterly". The piping for the Unit 2 ND system differs from the Unit 1 ND system piping, so only the testing for 2ND-70 is affected. The basis for relief is also revised accordingly to reflect this. [ Unit 2 only: Page II.34-5]

e Deletion of Unit 1 Safety Injection (NI) system valves INI-41A, 1NI-25A, 1NI-23A, and INI-24B from program. These valves have been deleted from the Safety Injection system as a result of the deletion (via installation of bypass piping) of the Unit 1 Boron Injection Tank (BIT). Note that changes to the Unit 1 inservice testing program as a result of the deletion of the Unit 1 BIT were originally addressed in Revision 8 to the Unit 1 IWP/IWV Program (reference H.B. Tucker (DPC) to H.R. Denton (NRC/0NRR) letter dated July 25, 1985); however, these valves were not included in that revision due to an oversight. (NOTE: The BIT on Unit 2 was removed prior to licensing of Unit 2, consequently there are no corresponding valves in the current Unit 2 program). [ Unit 1 only: Page II.35-2]

4 4 Mr. Harold R. Denton April 1, 1986 Page 5 e Correction of valve category and addition of " passive" notation for Safety Injection (NI) system valve NI-336. The reason for the inclusion of this valve in the inservice testing program is its containment isolation function (valve should be category "A,C", not just "C"). Although it is a relief valve, its safety function is closed and it is passive as far as its containment isolation function is concerned. Its pressure relieving capacity is just for hydro testing purposes. Consequently the only testing performed on this valve is local leak rate testing.

[ Units 1 and 2: Page II.35-12]

These revisions should be incorporated into your Unit 1 and 2 pump and valve inservice testing manual, removing any superseded pages of the program. Should there be any questions concerning the basis for any of the i changes, please advise. I Duke Power Company intends to implement the Unit I and 2 program as revised on an interim basis pending program approval by the NRC.

By copy of this letter, one copy of the above documents are also being provided to NRC-Region II.

Very truly yours, agggs{)f3IIr--- k 1
