1.

O rig ina l p reope ra t i ona l testing 2.

Post maintenance testing 3.

The first running of the test Although this method does not meet tho exact wording or IW-3f 17 it is a better method for discovering the slowly 4

C CODE REQUIREMENT The valves will not be exercised as required by IWV-3522.

BASIS System design does not permit the performance of a meaningful exercise test to verify the valve prevents reverse flow without excessive manipulation of components and systems involved. These operations are not warranted for the extent of testing to be accomplished. Specifically:

Ar-14-1. 3 These are norrally open check valves. Verification or valve closure requires taking one of the opposite units aux feedwater pumps out-of-service and draining approximately 200 feet of 8 inch pipe.

Taking one of the other units aux feedwater pumps out-of-service requires repositioning of valves, which if not performed properly, could result in a violation of the plant's operating license.

CC-3-3. 4 These a re normally open check valves. Verification of valve closure requires isolation or the following equipment and draining of long sections of piping.

Seal Water Heat Exchanger 4.

Letdown Heat Exchanger 5.

Reactor Coolant Pumps 6.

Excess Letdown Heat Exchanger The water in the system is chromated and its disposal presents an occupational and envi ronmental ha za rd.

VC-8-2. VC-17-1 These a re normally open check valves. The leak rate or VC-17-1 cannot be measured unless the leakage or VC-8-2 is greater than the leakage or VC-17-1.

The leakage or the series check valves, VC-8-2 and VC-17-1, will be measured, then the leakage of VC-8-2 will be measured to verify the valve (s) has (have) moved to the closed position.

F-8-1.

r-8-2 Stroking test valves requires operation of the aux feedvater pumps and the draining or a long section of 16 inch pipe.

Such an errort is not warranted to verify the check valves close.

CL-42-1. 2CL-42-1 These are normally open check valves. Verification of valve closure requires taking one entire safeguard cooling water header (both units) out or service and draining 200 feet or 30 inch pipe.

This valve was added to the Section XI program by NRC Bulletin 01-Q1, which was concerned about railure nr valve inte rna l parts and blockage of ricw to emergency dissel generators. Since there is continuous flow through the valve any degradation of the valve would be immediately noticed. Fu rthe rmo re, the valve design is such that railure of the valve internals could not block flow to the emergency diesels. This test would be an unnecessa ry challenge to the safeguard protection systems.

REQUEST FOR REllEF fcont'dl BASIS Exercising these valves at Cold Shutdown would create extensive operational problems, specifically:

CV-31440. CV-31241. CV-31444 Cycling these valves could potentially cause an over pressurization of the reactor coolant system with the RCS below MPT.

MV-32199. MV-32166. VC-14-1. VC-14-2 Cycling these valves could disrupt either seal water injection to the Reactor Coolant Pumps or seal leskorr from the Reactor Coolant Pumps.

Either or these errects might damage the pump seals.

VC-7-11. VC-7-10. CV-31198 Cycling these valves could remove the boric acid addition path from service. This path is required by Tech Specs.

CV-31436. CV-31437 Cycling these valves could isolate the Reactor Coolant Drain Tank.

The RCOT and its pumps are used as a drain down path and to purity the RCS at Cold Shutdawn. Removal of these functions would restrict plant activities.

CV-31434. CV-31435. CV-31545. CV-31546 Cycling of these valves could line up the vent header to the containment and cause a release or radioactive gases into the containment.

CV-31740. CV-31741 Cycling or these valves could isolate instrument air in containment. This would cause all or the air operated control valves to go to their failed position.

CV-31438. CV-31439 Cycling these valves prevents the removal or drain water from containment. This drain water comes from such evolutions as draining of systems for maintenance and draining of systems for startup.

Isolation could delay heatup or cause the overflowing or the sump and contamination or part of the containment.

2 CODE REgutR[M[NI The valves will not be exercised at cold shutdown conditions as required by IWV-3522.

BASIS Exercising these valves at cold shutdown would create extensive operational problems, specifically:

RC-3-1. RC-5-1 Exercising these valves could change the pressure in the Pressurizer Relier Tank and thereby affect the pressure of the Reactor Coolant System. This could increase the potential for a spill or contaminated water.

YE-R-h d C-gd Exercising these valves could disrupt seal water injection to the Reactor Coolant Pumps.

This could damage the pump seals.

YE-E-I Exercising this da t e could remove the boric acid addition path f rom service. This path is required by Tech Specs, CS-13. CS-12 See Request for Relier #5.

BASIS Valve design does not allow for easy access to valves for inspection or position. Specifically:

W-321MJ The valves are enclosed by valve enclosures which are part of the containment barrier.

It is not considered practical to disassemble these enclosures to verify correct position indication. Proper p*ositioning will be vertried by exercise tests (timing) and leak rate tests.

SV-37091 -6 these valves are solenoid valves which do not give physical indication or position. Proper position will be verirled by observing flow through the valves.

CODE REQUIREMENT The corrective action for valve exercise time will not be based on the last exercise time in the manner required by IWV-3417.

DASIS The base stroke times, f rom which the 25% or 50% increases are figured will not be the previous stroke time but a time established by any of the following methods.

1.

Original Preope ra t iona l Testing 2.

Post Maintenance Testing 3.

The first running of the test Although this method does not meet the exact wording of IWV-3417 it is better at discovering slowly degrading valve cycle times. This is the most common failure mechanism.

ALTERNATE INSPECTION fTESTING)

The 25% or 50% increase times will be determined from a pre-established stroke time.

CODE REQUIREMENTS The valves will not be leak rate tested in the manner reqt i red by IW-3420.

BASIS These valves are required by 10CFR 50, Appendix J (Primary Reactor Containment Leakage Testing for Watercooled Power Reactors) to have a minimum leakage, and are therefore Category A valves. Since the valves are required by Appendix J they will be leakrate tested, in accordance with Appendix J.

This includes the method, mea suremer;ts, medium, analysis, and corrective actions.

This is consistent with Section XI philosophy on containment Table IWE 2500-1 and IWE 5220 state pressure retaining boundaries of containment will be tested in accordance with 10CFR 50, Appendix J.

REQUEST FOR RELIEF (cont'd)

BASIS Exercising these valves at cold shutdown would create extensive operational problems spec t rically:

93-3153%_QV-31511. CV-31512 Cycling these valves could potentially cause an overpressurization of the reactor coolant system with the RCS below MPT.

Mv-3ggio tiv-32194. 2vC-19-1 2vC-14-2 Cycling these valves could disrupt either seal water injection to the Reactor Coolant Pumps or seal leakorf f rom the Reactor Coolant Pumps.

Either of these effects might damage the pump seals.

gVC I-11. EyC-7-19. CV-31211 Cycling these valves could remove the boric acid addition path from service. This path is required by Tech Specs.

17t L _GV-31731 Cl} lng these valves could isolate the Reactor Coolant Drain Tank.

i Cyci The RCDT and its pumps are used to purify the RCS at CSD and as a drain down path.

Removal of these functions would restrict plant activities.

GV-)R 1). CV-31735. CV-31731.CV-31732 Cycling of these valves could line up the vent header to containment and cause a release or radioactive gases to the containment.

CV-3JJi 2. CV-31743 l

Cycling of these valves will isolate instrument a i r in conta inment. This would cause all the a i r operated control valves to go to their railed position.

9V-31619. CV-3162D CycIlng these valves prevents the removal of drain water f rom containment. The drain water comes f rom such evolutions as draining of systems for maintenance and draining or systems for startup.

Isolation could delay heatup or worse, cause the overflowing of the sump and contamination of part of the containment.

ALTERNATE INSPECTION (TESTING)

The valves will be exercised at refueling and af ter ma intenance when they a re leak tested.

BASIS Exercising these valves at cold shutdown would create extensive operational problems specifica lly:

2RC-3-1. 2RC-5-1 Exercising these valves could change the pressure in the Pressurizer Relier Tank and thereby arrect the pressure of the Reactor Coolant System. This could increase the potential for a spill or contaminated water.

2vC-8-4,_gyC-O-5 Exercising these valves could disrupt seal water injection to the Reactor Coolant Pumps.

This could damage the pump seals.

2VC-8-1 Exercising this valve could remove the boric acid addition path f rom service. This path is required by Tech Specs.

Not per IWV-3426.

2.

Because or piping configurations, multiple valves will be tested at the same time.

Condition IWV-3424(b) will be followed, in that the total leakage or the multiple valves will be required to be less than the seat leakage for any one valve.

ALTERNATE INSPECTION (TESTING)

RM,3:La ndJS t 3 Leakage will be measured per IWV-3424(a) except that accumulator volume change instead or telltale drainage, will be used.

This is done to minimize chance or contamination and for ALARA.

Total leakage will be assigned to each individual valve.

This is done for ALARA.

MY:32162 Leakage will be measured per IWV-3424(b) except that the change in pressure will be used to determine apparent leakage, instead or maintaining a constant pressure. For significant changes in pressure the correction 90 IWV-3423(e) will be used.

MY-3212Lagd Mv-32g33 Leakage will be measured per IWV-3424(b), however, because or piping configuration the leakage or MV-32192 and MV-32232 will be added to the leakage of MV-32193 and MV-32233 to determine the leakage. MV-32193 and MV-32233 will be tested at reduced load per chance or contamination and for ALARA.

MY:32122_and MV-32232 Leakage will be measured per IWV-3424(a) except that pressure change or a test volume will be used.

lWV-3423(e) will be used for correction of leakage rate.

This is done to minimize the chance or contamination.

Additionally all valves are tested at flot Shutdown condition so that leakage is representative or at power and Hot S5utdown valves.
