2 r
l FUf;CTION: Valve opens to allow flow for containment spray. Valve l
closes to perform containment isolation function.
QUARTERLY TEST REQUIREMENT:
Verify forward and reverse flow operability per IWV-3522.
BASIS FOR RELIEF:
Forward flow operability can be verified only by i
initiating flow through-the. valves into the containment structure. The initiation of i
containment spray into the containment would result in extensive damage to equipment inside containment.
The only method available to verify reverse flow i
closure is valve leak testing during Appendix J,
type C, testing at refueling.
i l
ALTERNATE TESTING:
One of these valves will be disassembled and l
manually stroked every other refueling on a l
staggered test basis.
If disassembly reveals that the valve is-inoperable, the remaining valves will be disassembled.
In addition, reverse. flow closure will be verified during Appendix J, type C, testing at refue'i:1 These valves can not be partial exercised with flow after reassembly due to open discharge path inside containment. Appendix J 1eak rate testing after reassembly should confirm proper reassembly and disk alignment and will provide an adequate confidence.
level that check valve is functional.
GENERIC LETTER 04 REVIEW:
This relief request complies with the alternative to full flow testing of check valves as described in Position 2 of NRC Generic Letter 89-04. The l
provisions for extending the disassembly frequency have been reviewed and extension to every other outage is justified.

RELIEF REQUEST RR-28 SYSTEM:
Chemical and Volume Control - System 1208 VALVE:
2-1208-U6-124 CATEGORY:
C CLASS:
2 FUNCTION:
Isolate potential leakage path outside containment QUARTERLY TEST REQUIREMENT:
Verify reverse flow closure quarterly per IWV-3522(a).
BASIS FOR RELIEF:
Testing this check valve requires that letdown and Reactor Coolant Pump (RCP) seal water return to the Volume Control Tank (VCT) be isolated, thus, removing the Chemical and Volume Control System (CVCS) from service. The CVCS is required to be in service during normal operation. Therefore, quarterly testing is not possible.
Similarly, performing the test at cold shutdown would require isolating seal water to the RCPs. RCP seal water is typically only isolated during mid-loop operations when the Reactor Coolant System (RCS) level is below the RCP seals thus preventing 1
crud intrusion into the seal packages. There have been numerous undersirable events throughout the industry which have resulted from mid-loop operations, e.g., vortexing/ cavitation of the Residual Heat Removal (RHR) pumps due to improper RCS level indication. Mid-loop operation reduces RCS inventory which thereby reduces the plant's margin of safety. Therefore, the safety risks associated with testing this check valve during cold shutdowns are unwarranted.
ALTERNATE TESTING:
Reverse flow closure will be verified during each refueling outage by measuring a change in VCT level over time. This test will be performed in conjunction with the Emergency Core Cooling Systems (ECCS) check valve flow tests when the RHR system is I
providing flow to the suction of the centrifugal charging pumps. This check valve must close to prevent flow diversion to the VCT.
GENERIC LETTER 89-04 Review:
The proposed alternate testing method complies with Postion 3 of NRC Generic Letter 89-04.

RELIEF REQUEST RR-23 SYSTEM:
Main Steam - System No. 1301 VALVE (S):
1301-U4-008, 1301-U4-006 CATEGORY: C CLASS:
3 FUNCTION:
These valves open to allow steam to the AFW pump turbine and close to prevent reverse flow.
l QUARTERLY TEST REQUIREMENT:
Verify forward flow operability and reverse flow closure per IWV-3522.
BASIS FOR RELIEF:
Full-stroke exercising these valves during full power operation would require establishing full AFW pump flow into the steam generators. The introduction of cold water into the hot steam generators during full power operation results in a significant thermal shock to the feedwater nozzle. Subjecting the feedwater nozzle to this thermal transient on a quarterly basis decreases the fatigue life of the nozzle and could possibly result in nozzle cracking.
There are no system provisions for utilizing flow or pressure as an indication of reverse flow closure.
ALTERNATE TESTING:
These valves are partial-stroke exercised quarterly during the turbine-driven AFW pump test.
These valves will be full-stroke exercised on a cold shutdown frequency by verifying that the AFW pump is delivering the required flow through valves 1302-04-014, 1302-U4-017, 1302-U4-020, 1302-U4-023 and 1302-U4-026 as discussed in CS-19.
Reverse flow closure will be demonstrated by j
disassembly and manual full-stroke exercising on a staggered test basis at refueling. Valves will be exercised with flow after reassembly.
GENERIC LETTER 89-04 REVIEW:
This relief request complies with the alternative to full flow testing of check valves as described in Position 2 of NRC Generic Letter 89-04.
