ASME SECTION XI, SUBSECTION IWP i

The inservice testing of ASME Code Class 1, 2, and 3 pumps provided with an emergency power source will be tested as required by Section XI, Subsection

, IWP, of the ASME Boiler and Pressure Vessel Code 1980 Edition, except where

! specific written relief has been granted by the Commission. A description of the proposed inservice testing program, as well as specific requests for

relief f rom code requirements determined to be impractical, is described by

! the following.

!~

j 4 I. The following are specific requests for relief from certain code i requirements.

1 A) IWP-4120 requires the full scale range of each instrument to be three times the reference value or less. This was changed from four times the reference value in the edition of Section XI that was in effect prior to unit licensing. 10CFR, Section 50.55a(g)(4) states that design provisions are excluded from the requirement to

upgrade to subsequent editions of Section XI. Since any cases where j the three-times reference value criterion is not met would require design changes in instrumentation, we will continue to apply the four-times reference value criterion, as interpreted in B) below,

} for instrument accuracy evaluation.

! B) In several cases, instrumentation does not meet the four times 1

reference value criterion. These cases predominantly involve i suction pressure gauges where a larger range is required to

accommodate varying conditions at the suction of the pump. In all cases where the four-times reference value criterion cannot be met, an instrument error evaluation is performed to demonstrate that the

. overall accuracy of the differential pressure measurement is within the limits established by IWP. These cases are RHR discharge,

- nuclear service water suction, and control room chilled water suction gages.

j C) Table IWP-3100-1 establishes the parameters that are to be

] measured. The previous edition of Section 11 specified that in a fixed resistance system, either AP or Q was to be measured, not 4l both. Thecentrifugalchargingpumpsaretestedusingfixedresistancel flow paths, with no flow indication provided. Based on the design i change exclusion provided by 10CRF50.55a(g)(4), we will continue to apply the criterion that'it is not required to. measure flow in a fixed resistance system.

1

! D) Table IWP-4110-1 states that vibration measurement should have an 4 accuracy of i 5%. McGuire has no permanently installed vibration instrumentation. The portable instruments used to measure vibration have an uncertainty of t 11%.

McGUIRE - UNIT 1 I.1-1 Revision-4

II. The following Safety Class 1, 2, and 3 pumps (See Attachment #1 for specific safety class and available instrumentation) will be tested in accordance with the intent of Subsection IWP of the ASME code:

NUCLEAR SERVICE WATER PUMPS (IA, IB)

CONTAINMENT SPRAY PUMPS (IA, IB)

SAFETY INJECTION PUMPS (IA, IB)

MOTOR-DRIVEN AUX. FEEDWATER PUMPS (IA, IB)

TURBINE-DRIVEN AUX. FEEDWATER PUMP (NO. 1)

CENTRIFUGAL CHARGING PUMPS (IA, IB)

COMPONENT COOLING PUMPS (IA1, IA2, IB1, 1B2)

RESIDUAL HEAT REMOVAL PUMPS (IA, IB)

III. The following Safety Class 1, 2, and 3 pumps (See Attachment #1 for specific safety class and available instrumentation) will be tested in accordance with the intent of Subsection IWP, except for the request for relief for the specific requirements determined to be impractical as described below.

A) PUMP: CONTROL AREA CHILLED WATER PUMPS (CRA-P-1, CRA "-2)

SAFETY CLASS: 3 FUN CION: To provide chilled water to air handling units supplying control area air conditioning TEST REQUIREMENTS: 1. Measure pump bearing temperature during inservice testing.

2. Annually run pumps until bearing temperatures stabilize.

BASIS FOR RELIEF: There is no instrumentation installed to measure bearing temperature, and no meaningful data can be obtained from bearing housing surface temperature measurements.

ALTERNATE TESTING: The inservice testing of the Control Area Chilled Water Pumps will be in accordance with the intent of Subsection IWP except that bearing temperature will not be monitored and subsequently the pumps will not be run annually until bearing temperature 4 stabilizes.

IV. The following Safety Class 1, 2, and 3 pumps are provided with insufficient instrumentation to perform any meaningful testing in accordance with the intent of Subsection IWP and therefore the following alternate testing methods, as well as requests for relief from compliance with Subsection IWP, are described by the following. g McGUIRE - UNIT 1 I.1-2 Revision 4 1

l A) PUMP: D/G FUEL OIL TRANSFER PUMPS (IA, IB) !

SAFETY CLASS: 3 FUNCTION: Diesel generator auxiliary support TEST REQUIREMENT: Test pumps in accordance with Subsection IWP BASIS FOR RELIEF: Pumps contain insufficient instrumentation (See Attachment #1) to perform any meaningful testing in accordance with the intent of Subsection IWP.

ALTERNATE TESTING: Monthly Diesel Generator starting and loading as required by McGuire Technical Specifications is sufficient in assessing the hydraulic condition of the subject auxiliary pumps and demonstrating the capability of the individual components to perform their design function.

The mechanical condition of the subject pumps will be determined from vibration data to be gathered monthly. Flow will be monitored by observing level rise in the day tank.

B) PUMP: D/G ROOM SUMP PUMPS (IA2, IA3, IB2, IB3)

SAFETY CLASS: 3 FUNCTION: Water removal from Diesel Generator rooms TEST REQUIREMENT: Test pumps in accordance with Subsection IWP BASIS FOR RELIEF: Pumps contain insufficient instrumentation (See Attachment #1) to perform any meaningful testing in accordance with Subsection IWP.

ALTERNATE TESTING: Due to the anticipated infrequent normal operation of these pumps, quarterly, each pump will be verified to be capable of performing their design function of removing water from the sump at a rate greater than or equal to 419 gpm.

The time which it takes to pump a known volume 4 from the sump is recorded and converted to a flow rate.

DEFINITIONS OF TESTING REQUIREMENTS AND ALTERNATIVES j u

Cold Shutdown (CS) Testing will be performed when the unit is in a cold shutdown (Mode 5) whose planned length is of sufficient duration to establish necessary test conditions and to perform the test. In the case of frequent shutdowns, the testing will not be performed more than one per three (3) months.

Testing will commence as soon as the cold shut-down condition is achieved but not later than 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months after shutdown, and continue until 4 complete or the plant is ready to return to power. Completion of all valve esting is not a prerequisite to return to power. Any testing not completed at one cold shutdown will be per-formed during any subsequent cold shutdowns that may occur before refueling to meet the code-specified testing frequency.

Cycle and Time (CT) Valve will be tested to verify that its stroke time is less than the maximum allowable stroke time specified by McGuire Nuclear Station.

Leak Test (LT) Valve will be tested to verify that the seat leakage is limited to a specific maximum amount.

Movement Test (MT) Valve will be tested to verify that the valve is operable and/or the valve moves to the position required to fulfill its purpose. No timing is involved.

Quarterly (Q) Testing will be performed at least once per three (3) months.

Refueling Outage (RF) Testing will be performed when the unit is shut down for refueling (Mode 6). Safety valves will be tested periodically per the testing schedule defined in ASME Subsection IWV-3510.

Refueling Outage (RF*) Valve will normally be tested during refueling outages, however, testing is not required more often than once per 24 months per Appendix J to

/'"s. 10CFR50.

k)3 Setpoint (SP) Valve will be tested to verify that it will relieve pressure at its specified setpoint.

McGUIRE - UNIT 1 II.3-l' Revision 4

GENERAL RELIEF TEST REQUIREMENT: Perform trend analyses on category A and B valves as described in IW-3417(a).

BASIS FOR RELIEF: Trend analyses performed on rapid acting valves does not give reliable indication of valve stroke time deterioration.

TESTING ALTERNATIVE: Trend analyses will not be performed on valves that normally operate with cycle times of less 4

than 5 seconds. Maintenance will be initiated if valve time exceeds max. limit.

TEST REQUIREMENT: Cycle and time valve every three months.

BASIS FOR RELIEF: Failure of one of these valves in the closed position during testing would inhibit the flow path through the reactor coolant drain tank heat exchanger. No alternate flow path is available, which would force unit shutdown 4

until the valve is repaired. Steam would be released to the RCDT which would become overpressurized.

BASIS FOR RELIEF: Failure of one of these valves in the closed position would inhibit cooling flow to the containment. This would result in a steep rise in lower containment 4 temperature which could exceed tech. spec. limits and cause a plant shutdowm.

ALTERNATE TESTING: Valve will be cycled and timed during cold shutdowns.

VALVE: IVG-61, IVG-62, IVG-63, IVG-64, IVG-65, IVG-66, IVG-67, IVG-68 CATEGORY: B CLASS: C FUNCTION: Starting air solenoid control valves.

TEST REQUIREMENT: Verify valve operability every three months.

BASIS FOR RELIEF: This valve is automatically opened when the diesel generator engine is started. The valve will then close after the engine is started. Failure of this valve to j perform its required function should be indicated by the i diesel's performance when it is periodically tested (once I per 31 days). Direct observation of valve movement is impossible.

ALTERNATE TESTING: Valves will be considered to be functioning properly if l the diesel's starting time is within tech spec. limits.

MC-1593-1.0 VALVE: ISM-1AB, ISM-3AB, ISM-5AB, ISM-7AB, ISM-9AB, ISM-10AB, ISM-IIAB, ISM-12AB CATEGORY: B CLASS: B FUNCTION: Main Steam Isolation Valves.

TEST REQUIREMENT: C;rcle and Time Valves Quarterly.

BASIS FOR RELIEF: ISM-1, 3, 5, and 7, MSIV's, cannot be full stroke exercised during power operation since shutting an MSIV could result in a plant shutdown. Tech. Specs.

do not permit isolation of a steam generator. ISM-9 4

10, 11, and 12, MSIV Bypass valves, will be full stroke exercised quarterly. However, these valves cannot be timed at this frequency since this operation will be done utilizing a manual loader.

ALTERNATE TESTING: These valves will be partially stroked at least once per 92 days in accordance with PT/1/A/4250/01A (Main Steam Isolation Valve Movement Test). These valves will be full s stroked and timed at cold shutdown. ISM-9, ISM-le, 4 ISM-11, and ISM-12 will be full stroked quarterly and timed.

VALVE: IND-1B, IND-2A A

4l CATEGORY: l CLASS: A FUNCTION: Provides suction for Residual Heat Removal pumps during normal cooldown.

TEST REQUIREMENT: Verify proper valve movement every three months.

BASIS FOR RELIEF: These valves have been provided with an interlock which prevents their opening when the Reactor Coolant System 4 pressure is greater than 385 psig.

ALTERNATE TESTING: Valve will be cycled during cold shutdowns.

VALVE: IND-58 CATEGORY: B CLASS: B FUNCTION: Provides suction to the Centrifugal Charging Pumps from the Residual Heat Removal System.

TEST REQUIREMENT: Cycle valve every three months.

BASIS FOR RELIEF: Due to interlocks in the Safety Injection System and the actual Residual Heat Removal System design, it is impossible to test these valves without rendering both trains of Residual Heat Removal and both trains of Safety Injection inoperable during operation.

ALTERNATE TESTING: Cycle and time at cold shutdown.

. MC-1561-1.0 O VALVE: IND-71 CATEGORY: C CLASS: B FUNCTION: RER to SI Suction Check.

TEST REQUIREMENT: Full stroke exercise quarterly.

BASIS FOR RELIEF: Valve cannot be full stroked at power since the only full flow path is into the RCS and this can only be done with the reactor head removed at refueling.

IND-71 cannot be partial stroked during power since the required valve lineup would render both trains of safety injection inoperable. During cold shutdown,

. both SI pumps are tagged out to prevent a low tempera-ture overpressurization.

ALTERNATE TESTING: Valve will be full stroked at refueling.

, DUKE POWER COMPANY s MCGUIRE NUCLEAR STATION PUMP INSERVICE TESTING PROGRAM ASME SECTION XI, SUBSECTION IWP i

The inservice testing of ASME Code Class 1, 2, and 3 pumps provided with an emergency power source will be tested as required by Section XI, Subsection IWP, of the ASME Boiler and Pressure Vessel Code 1980 Edition, except where specific written relief has been granted by the Commission. A description of 4 the proposed inservice testing program, as well as specific requests for relief from code requirements determined to be impractical, is described by the following. l i

I. The following are specific requests for relief from certain code j i requirements.

i A) IWP-4120 requires the full scale range of each instrument to be !

] three times the reference value or less. This was changed from i j four times the reference value in the edition of Section XI that was 1 in effect prior to unit licensing. 10CFR, Section 50.55a(g)(4) states that design provisions are excluded from the requirement to upgrade to subsequent editions of Section XI. Since any cases where the three-times reference value criterion is not met would require ;

design changes in instrumentation, we will continue to apply the four-times reference value criterion, as interpreted in B) below, for instrument accuracy evaluation.

B) In several cases, instrumentation does not meet the four times reference value criterion. These cases predominantly involve suction pressure gauges where a larger range is required to accommodate varying conditions at the suction of the pump. In all cases where the four-times reference value criterion cannot be met, an instrument error evaluation is performed to demonstrate that the overall accuracy of the differential pressure measurement is within the limits established by IWP. These cases are RHR discharge, nuclear service water suction, and control room chilled water suction gages.

C) Table IWP-3100-1 establishes the parameters that are to be i

measured. The previous edition of Section 11 specified that in a fixed resistance system, either AP or Q was to be measured, not both. The centrifugal charging pumps are tested using fixed resistance flow paths, with no flow indication provided. Based on the design change exclusion provided by 10CRF50.55a(g)(4), we will continue to apply the criterion that it is not required to measure flow in a fixed resistance system.

D) Table IWP-4110-1 states that vibration measurement should have an ;

accuracy of + 5%. McGuire has no permanently installed vibration l

instrumentation. The portable instruments used to measure vibration ,

i have an uncertainty of + 11%.

II. The following Safety Class 1, 2, and 3 pumps (See Attachment #1 for specific safety class and available instrumentation) will be tested in accordance with the intent of Subsection IWP of the ASME code:

NUCLEAR SERVICE WATER PUMPS (2A, 2B)

CONTAINMENT SPRAY PUMPS (2A, 2B)

SAFETY INJECTION PUMPS (2A, 2B)

MOTOR-DRIVEN AUX. FEEDWATER PUMPS (2A, 2B)

TURBINE-DRIVEN AUX. FEEDWATER PUMP (NO. 1)

CENTRIFUGAL CHARGING PUMPS (2A, 2B)

COMPONENT COOLING PUMPS (2A1, 2A2, 2B1, 2B2)

RESIDUAL HEAT REMOVAL PUMPS (2A, 2B)

III. The following Safety Class 1, 2, and 3 pumps (See Attachment #1 for specific safety class and available instrumentation) will be tested in accordance with the intent of Subsection IWP, except for the request for relief for the specific requirements determined to be impractical as described below.

A) PUMP: CONTROL AREA CHILLED WATER PUMPS (CRA-P-1, CRA-P-2)

SAFETY CLASS: 3 FUNCTION: To provide chilled water to air handling units supplying control area air conditioning TEST REQUIREMENTS: 1. Measure pump bearing temperature during inservice testing.

2. Annually run pumps until bearing temperatures stabilize.

BASIS FOR RELIEF: There is no instrumentation installed to measure bearing temperature, and no meaningful data can be obtained from bearing housing surface temperature measurements.

ALTERNATE TESTING: The inservice testing of the Control Area Chilled Water Pumps will be in accordance with the intent of Subsection IWP except that bearing temperature will not be monitored and subsequently the pumps will not be run annually until bearing temperature stabilizes.

IV. The follcwing Safety Class 1, 2, and 3 pumps are provided with insufficient instrumentation to perform any meaningful testing in accordance with the intent of Subsection IWP and therefore the following alternate testing methods, as well as requests for relief from compliance with Subsection IWP, are described by the following.

McGUIRE - UNIT 2 II.2-1

l DEFINITIONS OF TESTING REQUIREMENTS AND ALTERNATIVES l( '

l Cold Shutdown (CS) Testing will be performed when the unit is in a cold shutdown (Mode 5) whose planned length is of sufficient duration to establish necessary test conditions and to perform the test. In the 4

case of frequent shutdowns, -the testing will not

. be performed more than one per three (3) months.

l' Testing will commence as soon as the cold shut-down condition is achieved but not later than 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months after shutdown, and continue until complete or the plant is ready to return to power. Completion of all valve testing is not

. a prerequisite to return to power. Any testing l not completed at one cold shutdown will be per-formed during any subsequent cold shutdowns that may occur before refueling to meet the code-specified testing frequency.

Cycle and Time (CT) Valve will be tested to verify that its stroke time is less than the maximum allowable stroke time specified by McGuire Nuclear Station.

t Leak Test (LT) Valve will be tested to verify that the seat leakage is limited to a specific maximum amount.

l

Movement Test (MT) Valve will be tested to verify that the valve is

! operable and/or the valve moves to the position required to fulfill its purpose. No timing is involved.

Quarterly (Q) Testing will be performed at least once per l

three (3) months.

Refueling Outage (RF) Testing will be performed when the unit is shut down for refueling (Mode 6). Safety valves will be tested periodically per the testing schedule defined in ASME Subsection IWV-3510.

Refueling Outage (RF*) Valve will normally be tested during refueling outages, however, testing is not required more often than once per 2' sonths per Appendix J to 10CFR50.

's( Setpoint (SP) Valve will be tested to verify that it will

', relieve pressure at its specified setpoint.

s McGUIRE - UNIT 2 II.3-1

GENERAL RELIEF TEST REQUIREMENT: Perform trend analyses on category A and B valves as described in IW-3417(a).

l BASIS FOR RELIEF: Trend analyses performed on rapid acting valves does not give reliable indication of valve stroke time deterioration. -

TESTING ALTERNATIVE: Trend analyses will not be performed on valves that normally operate with cycle times of less than 5 seconds. Maintenance will be initiated if valve time exceeds max. limit.

MC-2554-3.I VALVE: 2NV-223 CATEGORY: C CLASS: B FUNCTION: Opens on flow alignment from FWST -

TEST REQUIREMENT: Verify proper valve movement every three months.

BASIS FOR RELIEF: Testing of this valve requires opening ,aNV-221A or 2NV-222B. Failure of one of these valves in the open position aligns the WST to the suction of the charging pumps with no means of isolating the flow path. This would result in an increase in boron inventory in the RCS and could result in a plant shatdown. Full stroke exercising at cold shutdown could result in a low temperature overpressurization.

ALTERNATE TESTING: Valve will be partial stroked during cold shutdowns and full stroked during refueling.

TEST REQUIREMENT: Cycle and time valves every three months.

BASIS FOR RELIEF: Technical Specification 4.6.3.4 requires a leak rate test on these valves whenever they are cycled. In addition, Technical Specification 4.6.1.9 places severe restrictions on the operational time and alignment permitted for this system during normal operation. 2VP-1, 2VP-2, 2VP-3, and 2VP-4 may be opened- for only 90 hours0.00104 days 0.025 hours 1.488095e-4 weeks 3.4245e-5 months a year at power.

The rest of the VP valves may not be opened at all during power operation.

ALTERNATE TESTING: Valves will be timed whenever the system is operated or whenever the valves are cycled, and the elapsed time since the previous test has been three months or greater.

TEST REQUIREMENT: Verify valve operability every three months.

s BASIS FOR RELIEF: This valve is automatically opened when the diesel generator engine is started. The valve will then close after the engine is started. Failure of this valve to perform its required function should be indicated by the diesel's performance when it is periodically tested (once per 31 days). Direct observation of valve movement is impossible.

ALTERNATE TESTIFG: Valves will be considered to be functioning properly if the diesel's starting time is within tech. spec. limits.

1 MC-2561-1.0 VALVE: 2ND-1B, 2ND-2A CATEGORY: A CLASS: A FUNCTION: Provides suction for Residual Heat Removal pumps during normal cooldown.

TEST REQUIREMENT: Verify proper valve movement every three months.

BASIS FOR RELIEF: These valves have been provided with an interlock which prevents their opening when the Reactor Coolant System pressure is greater than 385 psig.

ALTERNATE TESTING: Valve will be cycled during cold shutdowns.

TEST REQUIREMENT: Cycle valve every three months.

BASIS FOR RELIEF: Due to interlocks in the Safety Injection System and the actual Residual Heat Removal System design, it is impossible to test these valves without rendering both trains of Residual Heat Removal and both trains of Safety Injection inoperable during operation.

ALTERNATE TESTING: Cycle and time at cold shutdown.

BASIS FOR RELIEF: Valve cannot be full stroked at power since the only full flow path is into the RCS,and this can only be done with the reactor head removed at refueling.

2ND-71 cannot be partial stroked during power since the required valve lineup would render both trains of safety injection inoperable. During cold shutdown, both SI pumps are tagged out to prevent a low tempera-ture overpressurization.

(+ O VALVE: 2NI-81, 2NI-70, 2NI-59, 2NI-93 CATEGORY: A, C CLASS: A FUNCTION: Opens on flow from the NI cold leg accumulator to the

~

Reactor Caclant System.

TEST REQUIREMENT: Verify valve opens when Reactor Coolant System pressure decreases below Safety Injection System pressure.

BASIS FOR RELIEF: Valves cannot be full or partial stroked during power operation since the accumulator pressure is % 425 psi and cannot overcome RCS pressure. During cold shutdown exercising these valves could result in a low temperature overpressurization of the RCS.

ALTERNATE TESTING: Valves will be partial stroked during cold shutdowns, but not more often than once per nine months. Valves will be full stroked at refueling.

TEST REQUIREMENT: Verify valve opens on flow from safety injection pumps once per three months.

BASIS FOR RELIEF: The discharge pressure of the safety injection pumps (1520 psig) is not sufficient for opening the valve to the Reactor Coolant System (2235 psig) during power operation.

RHR pumps, also, do not develop enough discharge pressure to overcome RCS pressure at power operation.

'i alternate source for suction to the Residual Heat Removal Pumps.

' BASIS FOR RELIEF: Due to interlocks in the Safety Injection System and the actual Residual Heat Removal design, it is impossible to test these valves without rendering both trains of Residual Heat Removal and both trains of Safety Injection inoperable. During cold shutdowns, the RHR pumps are required for decay heat removal.

! FUNCTION: Open when Reactor Coolant System pressure decreases below 1500 psig during accident conditions.

i TEST REQUIREMENT: Verify valves open on flow from upper head injection accumulator.

BASIS FOR RELIEF: The pressure in the UHI accumulator (1500 psig) is i not sufficient to open the valves into the Reactor ,

Coolant System (2235 psig). At cold shutdown, the high velocity water could cause damage to reactor internals. This, also, could cause low temperature overpressurization.
