ISI-T-100.0 SUSQUEHANNA STEAM ELECTRIC STATION UNIT 1 1

PUMP AND VALVEINSERVICE INSPECTION TESTING PROGR4M The pump and valve ISI testing program at the Susquehanna SES Unit 1 will be conducted in accordance with the 1980 Edition of Section XI of the ASME Boiler and Pressure Vessel Code incorporating through the Winter 1980 Addenda. Specific exceptions from these requirements are included here as Relief Requests. The inservice portion of the program commences at the receipt of the Operating License. Requirements for specific components commence concurrent with Technical Specification operability requirements.

For valves so equipped, remote position indicators will be utilized to demonstrate valve operability. Proper functioning of these position indicators will be demonstrated at least once every 24 months. Pressure relief valve testing will be conducted using test procedures which incorporate the testing methods of Section 4.09 of ANSI/ASMEPTC 25.3-1976. The provisions of Paragraph IWV-3511 shall begin at the receipt of the operating license. Thermal relief devices are excluded from the program. With the exception of valves providing a high pressure to low pressure boundary (pressure isolation function), valve leakage rate testing and acceptance criteria will be based on 10CFR50 Appendix J requirements as discussed in FSAR Subsection 6.2.6 and Susquehanna SES Technical Specification 3/4.6.1.2. Pressure isolation function testing is discussed below.

Excess flow check valves are installed on instrument lines penetrating containment in accordance with Regulatory Guide 1.11. As such, the lines are sized and/or orificed such that off-site doses will be substantially below 10CFR100 limits in the event of a rupture. Therefore, individual leak rate testing of these valves is not required for conformance with 10CFR50, Appendix J requirements. Functional testing of valves to verify closure can be accomplished by the process of venting the instrument side of the valve while the process side is under pressure. Such testing is required by Technical Specification 4.6.3.4 at least once per 18 months. Testing on a more frequent basis is not feasible for several reasons. Instruments serviced by these valves frequently have interlock or actuation functions that would be interfered with should testing be performed during plant operation. Also, process liquid will be contaminated to some degree, requiring special measures to collect flow from the vented instrument side. Functional testing with verification that flow is checked will be performed at least once per 18 months per Technical Specification 4.6.3 via SI-199-206, 207, 208, 209, 210, and 211. A listing of excess flow check valves can be found in Technical Specification Table 3.6.3-1.

Check valves whose safety function is to open will be full-stroke tested. Since disc position is not always observable, verification of the safety analysis design flowrate through the valve is considered an adequate demonstration of the full-stroke requirement. This convention is in agreement with NRC Generic Letter 89-04, Position 1.

Rev. 7 1D-1 12/91

ISI-T-100.0 Limit stroke times for power operated valves are provided and controlled in a general plant procedure in accordance with the NRC guidance provided by "Minutes of the Public Meetings on Generic Letter 89-04" (NRC Response to Question 38).

Where devices monitoring appropriate parameters exist permanently installed instrumentation will be used during pump performance testing. Both permanent plant instrumentation and measuring and test equipment will be maintained by the Instrumentation and Controls Section in accordance with their administrative procedures.

Valves in this category are subject to testing if they have not been tested in the previous 92 days. Testing shall continue until all subject valves are tested or the plant begins startup. Testing at subsequent cold shutdowns willcommence with those valves having the longest interval (if greater than 92 days) since previous tests. This definition applies to all relief requests with cold shutdown alternative testing.

Basis for Relief: These valves are in the cooling water supply and return lines for the reactor recirculation pump bearing and seal coolers. Cycling of these valves during power operation would interrupt this cooling water flow, possibly causing pump bearing damage or seal failure.

Alternative Testing: Exercise valves during Cold Shutdowns (no more frequently than once per 92 days).

Function: Containment Isolation Impractical Test Requirement: Exercise valves once per 92 days.

Basis for Relief: These check valves serve the containment isolation function inside containment and are not equipped with remote position indicators.

Downstream of the valves (inside containment) there are no pressure measurement devices or other means of remotely verifying valve position.

The only practical method of closure testing involves pressurizing the downstream side and measuring pressures with temporary instrumentation.

With the inerted containment, such testing can only be performed during a major outage which requires containment purging. This testing, which requires significant effort in the installation and removal of temporary equipment in the high radiation area of the containment drywell, is already performed during Category A leak rate testing.

Two valves, 1-26-152 and 1-26-154, serve a safety function on opening as well as their containment isolation function. The open test cannot be performed as there would be no positive indication (flow measurements) of function. Operation of the equipment serviced by these valves (ADS function of the safety/relief valves) will not verify their proper opening since the accumulators at the SRV operators provide capacity for several lifts.

Rev. 7 1RR2-1 12/91

ISI-T-100.0 RELIEF 'RE T ER 2 (Cont'd.)

Performing continued lifts in an attempt to verify check valve opening will increase the potential for SRV leakage or failure to reseat, will impact proper maintenance of reactor pressure control, and has the potential for degradation of the ADS function.

Alternative Testing: Valve closure is demonstrated by completion of leak rate testing performed once per 24 months. Commencing with the first refueling outage, verification of the opening capability of valves 1-26-152 and 1 154 will also be performed at that time with an air pressure applied through the outboard test valves (1-26-021, 1-26-03 1), opening the inboard test valves (1-26-155, 1-26-153), and observing essentially unrestricted flow.

Basis for Relief: These check valves remain open maintaining the flowpath to the vessel whenever the feedwater/condensate,'PCI or RCIC systems are providing makeup to the vessel or when Reactor Water Cleanup is returning flow to the vessel. Due to the necessity of maintaining this flowpath in virtually all modes of operation, closure testing is only practical during extended outages such as refuelings during which these systems are shutdown.

Also, plant design does not provide a practical means of demonstrating closure other than by upstream pressurization performed during leak rate testing. This testing involves significant effort for installation of temporary equipment, and requires complete purging of the inerted reactor containment.

Alternative Testing: Proper valve closure will be verified in by completion of leak rate testing performed once per 24 months.

Impractical Test Requirement; Paragraphs IWV-3417(b) and IWV-3523 of Section XI require that when corrective action is required as a result of tests made during cold shutdown, the condition shall be corrected before startup.

Basis for Relief: For those valves specified therein, the Limiting Conditions for Operation presently contained within the Susquehanna Steam Electric Station Technical Specifications provide the control by which valves and/or systems are declared inoperable. They also control entry into the various operational conditions. Further controls are not necessary for these valves. Valves which are not under the control of the Technical Specifications will be declared inoperable should they fail ISI testing.

Alternative Testing: The requirements contained within Susquehanna SES Technical Specifications will control plant operations and testing with regard to out-of-service valves.

Function: ADS Valve, Code Safety/Relief Valve Impractical Test Requirement: Exercise valve once per 92 days.

Basis for Relief: The six safety relief valves assigned to the ADS system perform an essential safety function when operated by the pneumatic actuator with gas supplied through the ADS solenoid valves. Operation of these valves is not practical during power operations because this action will vent main steam to the suppression pool, inducing a transient condition and increasing the potentiality for an open failure of a safety relief valve.

Also, no stroke timing is practical as these are pneumatic assisted SRVs.

Since "position indication" of the SRVs is provided by acoustic monitors attached to the valve discharge piping, exercising during cold shutdown cannot be accomplished because of lack of steam flow (and attendant noise).

Alternative Testing: The ADS valves willbe exercised once per 18 months in accordance with Technical Specification 4.5.1.d.2.b, which provides manual opening of each ADS valve with reactor dome pressure greater than or equal to 100 psig and observing either control valve or bypass valve response or corresponding change in measured steam flow. No stroke timing will be done.

Function: Containment Isolation Impractical Test Requirement: Exercise valves once per 92 days.

Basis for Relief: During full power operation, it is impractical to full stroke cycle these valves, since the interruption in steam flow would induce a reactor pressure transient with increased probability of reactor scram, main steam line isolation and SRV actuation. Trending of valve stroke times is not necessary due to Technical Specification limits on minimum as well as maximum allowable stroke times with a tolerance of 2 seconds.

Alternative Testing: Full stroke testing will be performed in Operational Condition 1, 2, or 3 when power level is low enough to prevent the above mentioned transients (no more frequently than once per 92 days). No reduction from high power levels will be made specifically to accomplish this testing. No trending of valve stroke times will be done.

Basis for Relief: In an alternative flowpath to the fuel storage pool, exercising of these valves utilizing flow can only be accomplished utilizing ESW or RHR water. Use of ESW would introduce "raw" water from the ESSW spray pond, undesirable for chemistry and fuel integrity considerations. While use of the RHR flowpath is possible, the difficulty of operating the RHR system in an abnormal lineup for supplying the fuel pool creates a dynamic control situation that is best minimized.

Alternative Testing: Verify valve operability by a pneumatic open flow path test during periodic pressure test. A pneumatic open flow path test (SE-135-301) is performed once per Inspection Period (as specified by ASME Code Section XI paragraph IWD-2400).

The valves are not equipped with remote indication and there is no pressure indication downstream of the valves. For these valves, closure testing is only practical through pressurization downstream of the valve with the upstream piping vented, and verification of the absence of flow upstream. Interruption of the CRD flow (seal purge) during Reactor Recirculation Pump operation to perform this testing could result in seal damage. This type of testing can only be performed during a period when the containment is accessible.

(per IWV-3411 and IWV-3521)

Basis for Relief: These valves located on the h draulic control units for the 185 contro 1 rod drives, perform the active safety function of rapidly inserting the control rods into the reactor core, upon receipt of a reactor scram signal from the reactor protection system. Exercising these valves quarterly during power operations could result in the rapid insertion of one or more control rods more frequently than desired. Where testing could result in the rapid insertion of control rods, thereby causing rapid reactivity transients and wear of the control rod drive mechanisms, the control rod scram test frequency identified in the Plant Technical Specifications will be utilized as the valve testing frequency.

Normal control rod motion has been shown to be an indicator that the associated cooling water header check valve (147138 -001 through -185) moves to its safety position (closed).

safety position (open), however. Since this check valve is moved to its open position only by scram exhaust flow, a positive test of the opening of the valve can only be provided by the periodic scram testing and control rod insertion timing specified by Technical Specification 4.1.3.2.

Verification that any charging water header check valve (147511 -001 through -185) moves to its safety position (closed), requires that the control rod drive pumps be stopped to depressurize the charging water header. This test cannot be performed during power operations because stopping the pumps would result in loss of cooling water to all control rod drive mechanisms and seal damage could result. This test cannot be performed during each cold shutdown because the control rod drive pumps supply seal water to the reactor recirculation pumps and one of the recirculation pumps might be kept running, thus continuing to need its seal water supply. The HCU accumulator pressure decay test, specified by Technical Specification 4.1.3.5.b.2, provides verification of the closure of its charging water header check valve.

The scram inlet valves (XV-147126 -001 through -185) and the scram exhaust valves (XV-147127-001 through -185) are air operated valves that full-stroke in milliseconds and are not equipped with position indication, thereby rendering measurement of their full-stroke times impractical.

Verifying that the control rod associated with each pair of these valves meets the periodic scram testing rod insertion time limits, specified by Technical Specification 4.1.3.2, is an acceptable alternate method of detecting degradation of these valves. Since these measurements of control rod insertion times are subject to the conservative limitations of Technical Specification 4.1.3.3, and because these measurements cannot be meaningfully correlated with the full-stroke times of the scram inlet and exhaust valves, trending of these scrams time measurements in any manner comparable to that of valve stroke times is both impractical and unnecessary.

N These bases for relief from applicable code testing requirements for these individual control rod scram valves are intended to conform to those provided as guidance by NRC Generic Letter 89-04 (Position ¹7).

Basis For Relief: These check valves, located in keepfill lines for the RHR, Core Spray, and HPCI Systems provide Condensate Transfer System water flow into their respective headers, while preventing flow of process water in the reverse direction, during operation of the respective ECCS System. In the RHR and HPCI Systems, test connections exist between the two tandem check valves existing in each line, while in the Core Spray System, a single test connection exists upstream of both check valves, which are located very close together. These configurations allow individual testing of the downstream check valve in the RHR and HPCI Systems, but support only dual testing of each pair of Core Spray System check valves in combination. Using these test connections in RHR, Core Spray, and HPCI to monitor essential restriction of reverse flow involves collecting radioactively contaminated seepage while the process system is pressurized, as during flow testing. This creates the potential for spills and spread of contamination. The increase in potential for water hammer in these systems due to isolation of keepfill lines during testing, the increase in personnel radiation exposure required to perform this testing during Rev. 7 1RR24-1 12/91

plant operation, and the increase in potential for contamination of personnel and equipment through this testing justify reduced frequency. The stainless steel construction of each check valve and the series configuration of each pair of check valves reduce the probability of failure to restrict reverse flow through any keepfill line.

The relatively small size of each keepfill line minimizes the impact of any such failure. The combination of these mitigating factors warrant reduction in testing frequency.

The single check valves located in the keepfill lines for the ESW System provide Service Water System flow into their respective headers, while preventing flow of process water in the reverse direction, during operation of ESW System. Test connections upstream of each check valve support testing of its reverse flow individually. Using these test connections in ESW to monitor essential restriction of reverse flow involves collecting raw service water seepage, which has the potential to chemically contaminate and degrade the operation of the plant Liquid Radwaste System. The stainless steel construction of each check valve reduces the probability of failure to restrict reverse flow through any keepfill line.

ISI-T-100.0 RELIEF RE T NUMBER 43 System: Standby Liquid Control P&ID: M-148 Pumps: 1P208 A,B Class:

Function: Standby Liquid Control Pumps Impractical Test Requirement: Measure inlet pressure prior to and during pump test and measure pump delta-p during pump test.

Basis for Relief: System configuration does not provide a pressure indicator on the pump suctions. It is possible to determine suction pressure by calculation from tank level (elevation difference) when the pumps are in normal alignment to the SLC Storage Tank. However, when pump testing is being performed, the tank is valved out and the suctions are aligned to a demineralized water header. While some estimation of the pressure in this alignment is available by the setting of the pressure control valve on the demineralized water header, no direct pressure indication is available. Since the SLC pumps are positive displacement type pumps, suction pressure will not affect developed discharge pressure.

Alternative Testing: Do not measure inlet pressure prior to or during pump tests. Utilize pump discharge pressure reading in lieu of Pump delta-p reading.

Function: Containment Isolation Impractical Test Requirement: Exercise valves once per 92 days.

Basis for Relief: These normally closed Isolation valves serve as the pressure isolation between CS system piping and reactor vessel pressure. In accordance with guidance presented in IE Information Notice 84-74, draft R.G.

901-4, and previous NRC concerns regarding intersystem LOCAs, cycling these valves every 92 days during power operation increases the probability of exposing the downstream low pressure piping to reactor coolant pressure (since only one valve would have to be ruptured or failed open to expose the low pressure system to reactor coolant pressure). In addition, failure of these valves after testing to positively reseat could cause loss of Core Spray system function.

Alternative Testing: Exercise valves during cold shutdown (no more frequently than once per 92 days).

Basis for Relief: With one loop out-of-service in a system, it is not desirable to test the redundant loop per ISI requirements as such testing may increase the chance of failure in a condition where backup equipment is not available. Also, these situations willbe governed by the Susquehanna Steam Electric Station Technical Specifications.

Basis for Relief: These pumps are a sealed-unit submersible type with the entire unit submerged in the Diesel Oil Storage Tanks. The Susquehanna Steam Electric Station Technical Specifications presently require at least a monthly functional test of these pumps. This test verifies fuel oil flow from the storage tank to each diesels skid-mounted day tank.

Similarly, the diesel oil firing pumps are tested during the diesel functional tests. These pumps take suction from the day tank and supply the diesel cylinders. SSES considers all these pumps an extension of the diesel engine equipment skid, and therefore all are adequately tested per Technical Specifications along with the diesel itself. In addition the actual flowrate for the diesel fuel oil transfer pumps is over five times the required diesel engine fuel usage at rated conditions. Thus, even a large reduction in pump flow will not affect system operability. The pump discharge check valves are similarly tested monthly via plant Technical Specifications.

Alternative Testing: Each pump will continue to be functionally tested at least monthly via Technical Specification 4.8.1.1.2. No other testing need be performed.

Basis for Relief: These pumps are driven by a steam turbine which exhausts steam into the suppression pool. Extended run times necessary to achieve stabilized bearing temperatures could heat the suppression pool water to a temperature exceeding the Technical Specification limitof 105'F.

Alternative Testing: Eliminate bearing temperature measurement. Vibration measurements will give adequate information concerning potential bearing temperature problems.

Impractical Test Requirement: a) IWP-3500(b), bearing temperature stabilization.

b) IWP-3500(a), five minute minimum run time.

Basis for Relief: One characteristic of positive displacement pumps is that there is essentially no lag time between starting the pumps and reaching equilibrium conditions. To measure pump flow rate, the measured rate of drainage from the test tank (IT-203) is measured. No installed instrumentation is available to measure flow rate. This testing configuration prevents recirculation of the pump discharge flow through the test tank during the test. Since the capacity of the test tank is 210 gallons and the pumps rated flow is 43 gpm, the tank will overflow before bearing temperature is stabilized. The pump bearings are located in a motor gearbox and no direct measurement of gearbox oil temperature is possible. The gearbox casing is not a reproducible measurement point. In addition, the test tank would be very close to if overflow a five minute run time test is performed.

Alternative Testing: Vibration measurements will give information concerning potential bearing problems. The pump flow rate willbe measured and changes in pump flow rate provide an early indication of degradation in pump performance. The pumps will be run for a period of time which will not cause the capacity of the test tank to be exceeded.

Basis for Relief: The ultimate function of these pumps is to provide chilled water to the cooling coils of the Control Structure HVAC system. Rather than individually testing each pump for proper functioning based on the prescribed measurements required by IWP, operation of the chilled water loop with cooling supplied by the emergency condenser loop provides a functional system test which is indicative of proper operation of all system components. This testing is more practical and provides a method of pump testing which does not require the removal of this safety system from operation. See Relief Request Number 40.

Function: Pump Discharge Check Impractical Test Requirement: Valve Internals Integrity Verification of NRC IEB 83-03.

Basis for Relief: These check valves, located in the pump discharge, are required to open during system operation to permit cooling water flow to system loads. During quarterly pump, tests, the valves are in fact cycled open and design flow passed through, indicating operability.

However, as discussed in IE Bulletin 83-03, such testing in raw water cooling systems may be inadequate to ensure valve mechanical integrity.

Alternative Testing: In addition to quarterly exercising in conjunction with pump tests, verify valve mechanical integrity by visual inspection during disassembly.

Impractical Test Requirements: Stroke time valves when exercised, once per 92 days.

Basis for Relief: The HPCI Turbine Stop Valve, FV-15612, has a design stroke time of 0.5 seconds. In keeping with current philosophy regarding other rapid-acting valves, this valve cannot be timed accurately and thus cannot be trended from test-to-'test. Minor variations in each test could cause needless additional testing, which would require rendering the HPCI system inoperable.

Basis for Relief: Full scale ranges of test instruments, as established by ASME Code Section XI paragraph IWP-4120, are limited to three times the reference value or less. In contrast, the four RHR System Pumps 1P202A/B/C/D have suction pressure reference values as low as 5 PSIG, but have suction pressure gages PI-1R002A/B/C/D permanently installed with full scale ranges 0-200 PSIG.

Similarly, HPCI System Pump 1P204 has a suction pressure reference value of 18 PSIG, but has suction pressure gauge PI-1R606 permanently installed with a full scale range of 0-85 PSIG.

These permanent plant instruments require the full scale ranges for which they have been designed and installed to be able to cover the full spectrum of operating conditions and configurations of their respective systems. These permanent plant instruments have greater reliability than temporary or permanent test instruments would have.

The permanent plant instruments used for these tests have had the accuracy of their calibration specially enhanced at the nominal values of the test parameters; their accuracy within the range of test values is adequate for test purposes. The use of the permanent plant-instruments for ISI pump testing ensures that pump suction pressures Rev. 7 1RR55-1 12/91

A method for indirect observation of valve movement, utilizing ferritic steel objects (steel shot) moved along the surface of each valve's indicating tube by the permanent magnet attached to the valve stem inside, was devised, used for 18 months, and subsequently abandoned because its employment necessitated partial disassembly of the solenoid valve for the test. This disassembly and reassembly, consisting of removal and reinstallation of the reed switch housing assembly, or cover, has been found to cause damage to the wiring and its connections to the reed switches.

MSIV M-141 141FO29D Function: Prevent reverse flow out through MSIV accumulator inlet (air) line.

Impractical Test Requirement: Exercise valves to their closed positions once per 92 days (per IWP-3521).

Basis For Relief: Thesecheck valves, located in MSIV accumulatorinlet(air) lines provide Containment Instrument Gas System and Instrument Air System gas fiow into their respective MSIV accumulators, while preventing flow of gas stored in the MSIV accumulator in the reverse direction, during closure of their respective MSIV's at the onset of a LOCA. Plant configuration and exclusion of personnel from the purged drywell during operation preclude completion of closure exercise testing throughout the period of each plant operating cycle.

Any exercise testing of these check valves requires or causes closure of the associated MSIVs, rendering it impractical except during refueling outages. The design basis of these check valves for the

, inboard MSIVs is established by PP&L Calculations M-MSS-025 and M-MSS-028, from which testing appropriate to their safety function is derived.

Alternative Testing: Demonstrate closure of each MSIV accumulator check valveby monitoring the essential restriction of its reverse flow of gas, through measurement of the rate of decay of pressure in its respective MSIV accumulator (downstream of the check valve under test) once per refueling outage. This MSIV accumulator pressure decay test provides verification of the closure of the inlet check valve.

> 25% (when over 10 seconds) or by >50% (when under 10 seconds).

Basis For Relief: These globe valves are air operated and have comparatively complex actuation logic schemes sequencing their start and stop times. P&ID M-147 Notes ¹21 & 22 establish additional restraints, which are satisfied administratively, upon the stroke times and sequencing of these valves. In addition to the common causes of inconsistency in rate of pneumatic actuation of valves, such as variations in air line supply pressure and variations in air regulator output pressure, the pneumatic actuators of these valves have their exhaust airflows metered by needle valves. Their actuation rate is extremely sensitive to the slightest changes in the positions of the needles in these needle valves, as caused by readjustment, by physical shock, or by thermal change. By readjustment of the exhaust needle valve position, these valves are maintained in compliance with the stroke time and sequencing limitations of the P&ID, which, although dissimilar from those of Article IWV-3000, provide a more relevant basis for verifying the operational readiness of these particular valves.

Alternative Testing: Exercise testing of the four valves is to be performed quarterly, per IWV-3410 requirements, except that the IWV-3417(a) stroke time increase limitations (of 25% above 10 seconds and 50% below 10 seconds) willbe replaced by P&ID M-147 Notes ¹21 & 22 limitations

Function: Containment Isolation Impractical Test Requirement: Exercise valves once per 92 days (per IWV-3411).

Basis For Relief: Closure of the reactor is operating causes an isolation of the RWCU System, initiating thermal and pressure transients within that system, which degrade the RWCU pump seals, leading to eventual damage to and consequent failure of the seals. Seal failure causes spread of radioactive contamination throughout affected parts of the reactor building and diminishes the reliability of the RWCU pumps. The necessary replacement of the pump seals requires isolation of the pump from the RWCU System, reducing the ability of the system to remove impurities from the reactor coolant. This results in degraded reactor water purity, which in'urn, stimulates intergranular stress

'corrosion cracking (IGSCC) of the reactor pressure vessel, its internal components, attachments, and associated piping. Additionally, the pump maintenance required to repair the seal failures causes excessive personnel radiation exposure (estimated at 20 Man-Rem/year),

contrary to ALARAprinciples.

Alternative Testing: Exercise valves during Cold Shutdowns (no more frequently than once per 92 days).

Class:

Impractical Test Requirement: Paragraph IWP-3100, Inservice Test Procedure requirement for pump speed to be adjusted to the reference speed.

Basis For Relief: These pumps are driven by a steam turbine which exhausts steam into the suppression pool, heating it toward its Technical Specification limit of 105'F. This is a severe limitation on test duration. Frequent test repetition is not desirable due to the strong transient nature of a HPCI quick start. Such quick starts are recommended by INPO and have been adopted as PP&L's test method. These factors make this test uniquely time-dependent. Pump speed is not directly controllable, but can only be achieved through coordinated manipulation of the pump flow controller and the test system throttling valve. Test results are extremely sensitive to variations in pump speed, from all sources.

Alternative Testing: When pump test speed differs from the reference speed by a measurable amount (10 RPM, or greater), the Corrective Action analysis, permitted by paragraph IWP-3230(c) may include a correction calculation, using the following relationship, to conform the test results at actual test speed to the reference speed:

Class:

Function: Provide Actuating Gas to Automatic Depressurization Feature of Main Steam Relief Valves.

Impractical Test Requirement: Exercise valves once per.92 days (per IWV-3521).

Basis For Relief: Closure of the subject valves for exercise testing interrupts instrument gas supply to the ADS solenoids of the Safety/Relief Valves, compromising their ability to provide the opening motive force for the ADS valves, in support of the long-term cooling ECCS function. Due to the configuration of the CIG System, depressurization and venting of sufficient pipe lines to permit closure exercise testing of these valves further interrupts instrument gas supply to several important valves inside containment, such as the Safety/Relief Valves (non-ADS relief function) and the MSIV'S. This could compromise the ability of the SRV's to operate in the relief mode which, while not an ECCS function, is important to safety. Loss of instrument gas supply could also cause the MSIV's to close, resulting in a severe reactor transient if operating; or in an undesirable ESF actuation, ifshut down. Loss of instrument gas supply could also cause isolation of the drywell cooling lines, resulting in a drywell temperature excursion.

Alternative Testing: Demonstrate closure of each check valve by monitoring the essential restriction of its reverse airflow, through the test connection downstream of the opposite division check valve, once per refueling outage.
