NINE MILE POINT NUCLEAR STATION, UNIT 2 PUMP AND VALVE INSERVICE TESTING PROGRAM QUESTIONS AND COMMENTS 1.
VALVE TESTING PROGRAM A.
General uestions and Comments l.
If a manual operator is used to full-stroke exercise check valves that cannot be full-stroke exercised with flow, is the force or torque that is applied to the mechanical exerciser measured to assure compliance with IWV-3522(b)?
2.
The NRC has concluded that the applicable leak test procedures and requirements for containment isolation valves are determined by 10CFR50, Appendix J.
Relief from paragraphs IWV-3421 through 3425
-for containment isolation valves presents no safety problem since the intent of IWV-3421 through 3425 is met by Appendix J requirements,
- however, the licensee shall comply with Paragraphs IWV-3426 and 3427.
General Relief Request GVRR-1 does not comply with this staff position.
3.
Provide a listing of all valves that are Appendix J, Type C, leak rate tested which are not included in the IST program and Categorized A or AC?
4.
The NRC staff has identified rapid-acting power operated valves as those which stroke in 2 seconds or less.
Relief may be obtained from the trending requirements of Section XI, Paragraph IWV-3417(a), however, in order to obtain this Code relief the staff does require that the licensee assign a maximum limiting stroke time of 2 seconds to these valves and comply with the requirements of IWV-3417(b) when the 2 second limit is exceeded.
General valve relief request GVRR-3 does not comply with this staff position.
5.
Provide the limiting values of full-stroke times for the power operated valves in the Nine Mile Point Nuclear Station, Unit 2, IST program for our review.
What are the bases used to assign the limiting values of full-stroke time for these valves?
6.
When flow through a check valve is used to indicate a full-stroke exercise of the valve disk, the NRC staff position is that verification of the maximum flow rate identified in any of the plant's safety analyses through the valve would be an adequate demonstration of the full-stroke requirement.
Any flow rate less than this will be considered partial-stroke exercising unless it can be shown (by some means such as measurement of the differential pressure across the valve), that the check valve's disk position at the lower flow rate would permit maximum required flow through the valve.
Does the Nine Nile Point Nuclear Station, Unit 2, IST program conform to this staff position?
7.
The relief request and cold shutdown justification bases should indicate the negative consequences that make testing at the Code required frequency impractical such as endangering personnel, damaging equipment, or resulting in a plant shutdown.
8.
Which valves at Nine Nile Point Nuclear Station, Unit 2, are currently leak rate tested to verify a pressure boundary isolation function?
9.
Provide a more detailed technical justification for not testing the excess flow check valves quarterly during power operations and during cold shutdowns (refer to General Relief Request GVRR-2).
10.
How are the remote position indicator s being verified for solenoid operated valves in the Nine Nile Point Nuclear Station, Unit 2, IST program?
ll.
Section 1.3.2 on page 1-3 states that "certain components" may be upgraded to later editions and addenda of the Code.
The NRC staff position is that individual components cannot be upgraded by
themselves, the entire pump program and or the entire valve program should be based on the same edition and addenda of the Code.
12.
Provide P8 IDs 52A AND 52G for our review.
B.

4.
Valve sample disassembly and inspection utilizing a manual full-stroke exercise of the valve disk is an acceptable method to verify a check valve's full-stroke capability.
This program involves grouping similar valves together and testing one valve in each group during each refueling outage.
The sampling technique requires that each valve in the group be of the same design (manufacturer,
- size, model number and materials of construction) and have the same service conditions.
Additionally, at each disassembly it must be verified that the disassembled valve is capable of full-stroking and that its internals are structurally sound (no loose or corroded parts).
A different valve of each group is required to be disassembled, inspected and manually full-stroke exercised at each refueling outage, until the entire group has been tested.
If it is found that the disassembled valve's full-stroke capability is in
- question, the remainder of the valves in that group must also be disassembled, inspected and manually full-stroke exercised during the same outage.
Does the Nine Mile Point Nuclear Station, Unit 2, disassembly and inspection program for valves 2SWP*V201A, V201B, VBOOA, V800B, V802A, and V802B conform to this staff position (refer to Relief Request

performed for valves 2SWP*AOV78A and AOV78B.
Are these valves equipped with remote valve position indication? If so, this indication should be verified in accordance with the Code requirements.
7.
Where "periodic testing" is identified in the remarks section for service water system valves, if this testing frequency is less than quarterly then a cold shutdown justification or relief request must be provided for the increased interval.
8.
Provide a more detailed technical justification for not exercising valves 2SWP*MOV77A and MOV77B during cold shutdowns (refer to Relief Request No.
SWP-VRR-2).

GPRR-17 Are the indicated ranges based on peak vibration readings or on RMS values?
4.
