Subject:
McGuire Nuclear Station, Units 1 and 2 Docket Nos.-50-369 and 50-370 Pump and Valve Inservice Testing Program NRC Review / Program Revision 13 (Unit 1) and 9 (Unit 2) (Relief Request No. 89-04) (TACS 61271/61272) Gentlemen: { Among the issues discussed at a meeting between Duke Power Company and NRC (with Technical assistance from their contracted reviewer, EG&G Idaho, Inc.) held August 16 and 17, 1988 to finalize the McGuire Nuclear Station Pump and Valve Inservice Testing (IST) Program, were the accuracy of Duke's portable vibration instrumentation, the pump vibration monitoring program units utilized, and bearing' temperature measurement requirements [Ref. Mr. D. S. Hood's (NRC/0NRR) letter to me dated September 8, 1988, pump testing program questions Nos. 3, 4, and 5). As a result of the above mentioned discussions, Notes 2 and 3 were included in IST Manual Section I.1, along with General Relief Requests B and C in Section 1.3, in the IST Program revision submitted October 31, 1988 (Unit 1 Revision 11 and Unit 2 Revision 7). These noted that-McGuire's vibration ceasurement accuracy was i 11%, 1 and that the vibration measuring equipment would be upgraded to meet the ASME IWP instrument ~ accuracy requirement and vibration measurements changed i from displacement to velocity by June 1, 1989 (after changing to velocity l vibration measurements, bearing temperature measurements would be dropped from the IST Program). However, by letter dated June 6, 1989 I informed you that the June 1, 1989 j date.was not met, and that Duke had investigated the available vibration j measuring equipment to evaluate which machine could best meet the needs of l our three nuclear stations (McGuire, Oconce, and Catawba). Although the vibration measuring equipment to be used by each station had been i determined, it had been discovered this equipment may not meet the vibration instrumentation requirements of IWP (and ANSI /ASME OM-6). Consequently, Duke was pursuing IWP vibration accuracy requirements and hoped to resolve l the problems in the near future for all three nuclear stations. Plans had been developed to determine the best obtainable accuracy for this equipment and relief would be requested for IWP vibration monitoring requirements that are impractical. In addition, I also informed you that due to delays' caused /)o17 n 9001020319 891214 t PDR ADOCK 05000369 J .O PM t.
3: Document Contral Dc:k .c P ga 2 h December 14, 1989 by an unexpected steam generator tube rupture outage McGuire had not yet implemented the change from displacement to velocity vibration measurements (McGuire was measuring displacement and performing bearing stabilization in accordance with IWP; General Relief Requests I.3 B and C had not been exercised for either unit), and that McGuire was pursuing the change from displacement to velocity vibration measurements and planned to achieve implementation by October 10, 1989. Accordingly, please find enclosed (pursuant to 10 CFR 50.4 and 50.55a(g)) for NRC Staff use and review 10 copies of Unit 1 Revision 13 and Unit 2 Revision 8 of the McGuire Nuclear Station Pump and Valve Inservice Testing Program. Duke Power Company has completed its evaluation of available vibration measuring equipment and respective accuracies. IWP General Relief Request I.3B has been revised to identify the following vibration measuring component. accuracies calibrated over a frequency range of 10 to 1000 Hz: e Accelerometer - 17.3% of reading Data Collector - 15.0% of full scale (full scale is 1 volt) e or 16.0% of total / absolute accuracies l Accuracies listed are the best our Standards Lab can produce with present state of the art equipment. ASME IWP does not specify Acceptance Criteria for vibration measured in velocity. Acceptance Criteria ranges have been added to IMP General Relief Request I.3B. The development of these ranges is based on current vibration standards and requirements of ANSI /ASME OM-6. Following the requirements of ANSI /ASME OM-6, additional vibration measurement points have been added. A summary of all the vibration measurement points is given in IWP General Relief Request I.3 B. For close-coupled pumps, the vibration point will remain on the lower motor i bearing in accordance with IMP-4510. The transition from measuring vibration in displacement to measuring in velocity will require measuring both during an initial test. As of October 10, 1989, performance of IWP pump tests includes bearing vibration velocity measurements. Our velocity measuring vibration equipment has been calibrated to the above specifications, and procedure changes performed to include velocity along with present displacement measurements. The displacement measurements will be compared against present acceptance criteria. If this comparison is satisfactory, velocity measurements will be analyzed and acceptance criteria developed in accordance with IMP General Relief Request I.3B. Velocity measurement acceptance criteria will be added to procedures and displacement measurement acceptance criteria will be deleted. Completion of this switchover for all pumps is expected to take J approximately six months. In addition, after the velocity measurement I acceptance criteria has been added to our procedures, annual measurement of bearing temperatures will be deleted (IWP General Relief Request I.3C). l l The above described changes to IWP General Relief Request I.3B constitute the major change to McGuire's IWP program. Additional minor changes to the IWP Program, as well as changes to the IWV Program, included in this IST l a [
[: h .s n e Document Control Enk Page 3 December 14, 1989 program revision are described in Attachments 1 (IWP changes) and 2 (IWV changes). Justifications / basis for the changes are included where necessary (i.e. where not obvious or self-explanatory or an administrative type change, etc). This revision complies with the guidance provided in Generic Letter 89-04 for making modifications to IST Programs. These revisions should be incorporated into your Unit 1 and 2 Pump and Valve Inservice Testing Program Manual, removing any superseded pages of the program. It is my understanding that the upcoming NRC SER on the McGuire IST Program (as discussed in my April 19, 1989 letter) will require certain changes to the McGuire IST Program. Although the enclosed changes are not expected to be able to be reflected in the SER, Duke did not consider it prudent to wait until receipt of the SER and subsequent Duke review / evaluation before making the enclosed program changes (along with any others that may be required by the SER). Duke Power Company intends to implement the Unit 1 and 2 program as revised on an interim basis pending program approval by the NRC. Please note that since this submittal provides material to be incorporated into our previously transmitted IWP/IWV Pump and Valve Inservice Testing Program (originally submitted for NRC review and approval on November 14, 1978 (Unit 1) and March 31, 1983 (Unit 2) which is still currently under review and has not yet received formal NRC approval, no additional fees pursuant to'10 CFR 170'are applicable (the IST Program is part of the operating license application and fee for its review / approval should be covered by the fee for the operating license applications for McGuire Nuclear Station Units 1 and 2). Once the IST program has received final NRC approval any subsequent revisions would then be subject to approval fees in accordance with the provisions of 10 CFR 170. If additional information is needed regarding the basis for any of the enclosed revisions (especially with respect to any impacts on the McGuire IST Program SER which is currently being written), or if Duke can otherwise aid in the IST review / approval process, please contact P.

4 I DUKE POWER COMPANY McGUIRE NUCLEAR STATION - UNIT 1 PUMP INSERVICE TESTING PROGRAM ASME SECTION XI, SUBSECTION IWP INTRODUCTION 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 anc Pressure Yes ui Code 1980 Edition, except where specific written relief has been grahted by the Nuclear Regulatory Commission. A description of the proposed intervice testing program, as well as specific relief requests from code requirements determined to be impractical, is described in this submitta). NOTES: 1) IWP-6240(f) requires the signature of the person or persons re3ponsible for conducting and analyzing the test. The dated initials of the person or persons responsible for conducting and analyzing the test may be used in place of a signeture in the record of tests. Initials shall be construed as signatures to meet the intent of IWP. 2) IWP-4110 requires instrument accuracy to be within the limits of O Table IWP-4110-1. For vibration, the acceptable instrument accuracy is 15% of full scale. Presently, the accuracy of the meter being used for displacement vibration measurements is 111%. Test instrumentaticn for velocity vibration measurements meets the instrument accuracy identified in General Relief Request I.38. Velocity and displacement vibration measurements are being measured currently. Displacement measurements will be dropped after velocity measurement acceptance criteria is 13 developed. 3) Af ter changing to velocity vibration measurements only, bearing temperature measurements will be dropped from our IST program. 4) Deleted O Rev. 13

i i 1 1.3. The following are general requests for relief from certain code requirements. (A) PLMPS: All pumps included in the IST program. TEST REQUIREMENT: Table IWP-3100-l' requires measuring static suction pressure (Pi) prior to pump startup. l BASIS FOR RELIEF: This measurement ensures adequate NPSH is i available. Occasionally, pumps may be in service supporting normal plant operation. In these cases NPSH requirements have already l been verified and it is not required to shut down an operating pump to measure static suction pressure. ALTERNATE TESTING: For pumps operating at time of test, static l suction pressure (P1) will not be measured. I 1 l 0 O
p (t) PUMPS: All pumps included in the IST program. TEST REQUIREMENT: IWP-3100 and IWP-3300 require vibration amplitude to be measured. IWP-3210 specifies the allowable ranges of vibration amplitude measurements. IWP-4110 requires the accuracy of vibration amplitude measurements to be +/-5% of full scale. IWP-4120 requires the full-scale range of vibration instrumentation to be three times the reference value or less. IWP-4510. requires displacement vibration amplitude to be read at one specific location during each test. IWP-4520(b) requires the frequency response range of vibration instrumentation to be from one-half minimum speed to at least maximum pump shaft speed, BASIS FOR RELIEF: Experience has shown that measuring vibration as required by IWP is not the most effective way to determine the mechanical condition of a pump. In order to better determine the mechanical condition of pumps, multiple vibration velocity measurements will be 4 obtained/ evaluated and supplemented, when necessary, with acceleration / displacement measurements and spectral analysis. In order 13 Q to facilitate this testing, digital vibration v instrumentation will be used. 6 IWP does not provide adequate guidance / requirements for performing the better/ alternate testing. ALTERNATE TESTING: In lieu of the vibration requirements of IWP-3100 and IWP-3300, peak vibration velocity be will measured. In most cases, vibration velocity gives the best indication of machine mechanical condition. 4 In lieu of'IWP-4520(b) vibration instrumentation will be calibrated and vibration velocity will be measured over a range of 10 to 1000 Hz. (Measurements at other frequencies will be taken as necessary.) This is the range that the state of the art instrumentation used can be adequately calibrated over. This range will encompass most potential noise contributors. O Rev. 13 i
4 O In lieu of the vibration instrument accuracy requirements of IWP-4110, vibration instrument accuracies will be within the limits specified below. These accuracies will be used because IWP does not specify accuracies for vibration velocity. These accuracies are the best that can reasonably be.obtained from the state of the art instrumentation used. (The requirements of IWP allow vibration inaccuracies of greater than +/-15% of reading.) Accelerometer: +/-5% of reading. (Due to the 4:1 rule, a lab uncertainty of +/-2,3% has to be added to the accelerometer uncertainty for a total / absolute accuracy statement of +/-7.3% of reading.) Data Collector: +/-5% of full scale (full scale is 1 volt) or +/-6% of velocity readings. (These are total / absolute accuracies.) 13 In lieu of the range requirements imposed on vibration instrumentation by IWP-4120, there will be no vibration instrumentation range requirement (digital vibration instrumentation. is auto-ranging). It is not necessary to have a range requirement because the accuracies stated above and the readability of a digital gauge are not dependent upon instrument range. In lieu of the vibration ranges specified in IWP-3210, the following ranges shall be used. These ranges shall be used because IWP does not specify ranges for vibration velocity. These ranges are based on current vibration standards (vibration severity charts).

This location shall be one of the j following: Pump casing 13 Motor bearing housing i Measurements also shall be taken in the axial direction. This measurement shall be taken on i each accessible pump thrust bearing housing, If no pump thrust bearing hcusings are accessible, this measurement shall be taken at-the accessible location that gives the best ~ indication of axial pump vibration. This location shall be one of the following: Pump casing Motor thrust bearing housing Motor casing On reciprocating pumps, a measurement shall be taken on the bearing housing of the crankshaft, ap' proximately perpendicular to both the crankshaft and the line of plunger travel. O New Page - Rev. 13
(C) PUMPS: All pumps included in the IST program. TEST REQUIREMENT: IWP-3100. IWP-3300 and IWP-3500 require the annual measurement of bearing temperature. BASIS FOR RELIEF: The yearly measurement of bearing temperature for pumps does not provide any meaningful information. Several factors such as the temperature of the working fluid, the ambient temperature, and lubricant temperature and the size of the bearing housing will mask any bearing condition change short of a catastrophic failure. Obtaining these measurements requires a minimum of one-half hour of pump operation to achieve stable bearing temperatures. The small probability of detecting bearing failure by temperature measurement does not justify the additional pump operating time required to make the measurement. ALTERNATE TESTING: Quarterly pump bearing vibration signatures will be used to evaluate pump mechanica) condition and to detect bearing degradation. The velocity signatures provide a better 33 indication of bearing performance since these measurements are not substantially affected by O outside influences. ANSI /ASME OM-6 has dropped the IWP bearing stabilization requirement since no real trendable data can be obtained, j 1 l Xav. 13
i I.4 The following Safety Class 2 and 3 Pumps (see Section 1.2 for available instrumentation) will be tested in accordance with the intent of Subsection IWP of the ASME Code, except where relief requests have been written for specific requirements determined to be impractical as described below: (A) PUMPS: Control Area Chilled Water Pumps (CRA-P-1 and CRA-P-2) SAFETY CLASS: 3 FUNCTION: To provide chilled water to air handling units supplying control area air conditioning. TEST REQUIREMENTS: IWP-3100, IWP-3300 and IWP-3500 require the annual measurement of bearing temperature. 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. In addition, ANSI /ASME 019-6 has dropped the bearing stabilization requirement since no real 13 trendable data can be obtained. ALTERNATE TESTING: The inservice testing of the Control Area Chilled Water Pumps will be in accordance with the intent of Subsection IWP axcept that bearing temperature will not be monitored and subsequently the pumps will not be run annually until bearing temperature stabilizes. O Rev. 13 i
(S) PUMPS: D/G Fuel 011 Transfer Pumps (1A, 18) SAFETY CLASS: 3 FUNCTION: Diesel Generator Auxiliary Support TEST REQUIREMENTS: Test pumps in accordance with Subsection IWP BASIS FOR RELIEF: IWP does not provide appropriate provisions for testing positive displacement pumps. ALTERNATE TESTING: The Fuel 011 Transfer Pumps are internal gear positive displacement pumps. The performance curve for these pumps is relatively flat. Capacity of these pumps is independent of discharge pressure when operating properly and operating below the cracking pressure of the pump internal relief valve. Discharge pressure will be measured for information purposes, but will not'be compared to any acceptance criteria. Pumps will be tested by measuring level rise in the Fuel Oil Day Tank and converting this to flowrate. Pump testing is between the level setpoints of the Fuel Oil Day Tank and this gives a run time of approximately 60-75 seconds. The flowrate (Q) will be 12 compared to acceptance criteria established in O accordance with Table IWP-3100-2 except the Acceptable Range has been widened and the High Alert Range increased to allow for level instrument fluctuations. Acceptable Range: 0.94 to 1.07 Qr Low Alert Range: 0.90 to 0.94 Qr High Alert Range: 1.07 to 1.10 Qr Low Required Action Range: <0.90 Qr High Required Action Range: >1.10 Qr These pumps are designed to produce a flowate of 22 gpm. The system design flowrate requirement for the pumps is 11 gpe. This difference provides a comfortable margin in the event a reference value is falsely established that would allow approximately 12% pump degradation before requiring any action in accordance with IWP.

No lubrication level verification is required for this pump. Lubrication is maintained under our routine preventative maintenance program. i The mechanical condition uf the subject pumps will be determined from vibration data to be f gathered quarterly. No bearing temperature 33 instrumentation is installed. ANSI /ASME OM-6 will not require bearing temperature measurements. In addition, monthly Diesel Generator starting and loading (as required by McGuire Technical Specifications) will assess the hydraulic 1 i condition of the subject auxiliary pumps and demonstrates the capability of the individual components to perform their design function. I i i l O Rev. 13
l (C) PUMPS: Safety Injection Pumps (1A, 18) SAFETY CLASS: 2 FUNCTION: To provide emergency core cooling in the event of a break in either the reactor coolant or steam system piping. TEST REQUIREMENT: IWP 3100 requires the resistance of the system to be varied until either the measured differential pressure or the measured flow rate equals the corresponding reference value. 13 BASIS FOR RELIEF: The previous edition of Section XI specified that in a fixed resistance system, either DP or Q was to be measured, not both.
- 10CFR, Section 53.55a(g)(4) states that design provisions are excluded from the requirement to upgrade to subsequent editions of Section XI.
ALTF.RNATE TESTING: The Safety Injection Pumps are tested using fixed resistance flowpaths with flow indication available. Since no flow adjustment is available, a flow will be recorded but will not be used for comparison to any reference values. O O t O O Rev. 13
(0) PUMPS: Residual Heat Removal Pumps (1A, 18) SAFETY CLAS$: 2 FUNCTION: To remove heat energy from the core and Reactor Coolant System during cooldown and refueling operations. Also, utilized as part of Safety 1 Injection System and Containment Spray System during an accident condition. l TEST REQUIREMENT: IWP-3100 requires the resistance of the system to be varied until either the measured differential pressure or the measured flow rate equals the corresponding reference value. BASIS FOR RELIEF: The previous edition of Section XI specified that in a fixed resistance system, either DP or Q was to be measured, not both.
- 10CFR, Section 50.55a(g)(4) states that design provisions are excluded from the requirement to upgrade to subsequent editions of Section XI.
j ALTERNATE TESTING: The Residual Heat Removal Pus.ps are tested using fixed resistance flowpaths with flow l indication available. Since no flow adjustment l is available, a flow will be recorded but will not be used for comparison to any reference i j values. O
(E) PUMPS: Centrifugal Charging Pump (1A, 18) SAFETY CLASS: 2 FUNCTION: To supply reactor coolant inventory in the volume control Tank or Refueling Water Storage Tank to the reactor coolant systoa. 13 TEST REQUIREMENT: Table IWP-3100-1 requires measuring differential pressure (DP) and flow rate (Q). BASIS FOR RELIEF: The previous edition of Section XI specified that in a fixed resistance system, either DP or Q was to be measured, not both.
- 10CFR, Section 50.55a(g)(4) states that design provisions are excluded from the requirement to upgrade to subsequent editions of Section XI.
ALTERNATE TESTING: The Centrifugal Charging Pumps are tested quarterly using fixed resistance flow paths with no flow indication provided. To supplement this quarterly testing, Centrifugal Charging Pump testing at emergency design flow conditions will be performed during refueling outages (starting in 1990). O Rev. 13 1
~ (F) PUMPS: D/G Room Sump Pumps (1A2, 1A3, 182, 183) SAFETY CLASS: 3 FUNCTION: Water removal from Diesel Generator Rooms TEST REQUIREMENT: Test pumps in accordance with Subsection IWP. BASIS FOR RELIEF: The 0/G Room Sump Pumps are vertical pumps tested by filling the 0/G Room Sump and pumping the sump down. No stable system conditions can be obtained due to the continuous decrease in sump level. No suction pressure, flow, bearing temperature, or lubricant level instrumentation is available. ALTERNATE TESTING: The 0/G Room Sump Pumps will be tested for greater than or equal to emergency design flow by: (1) Filling the sump and recording level. (2) Pumping down the sump and recording both level and pump down time. An average flow rate will be determined from the time it takes to pump a known volume from the sump. Pumping down the sump takes approximately 60 seconds. An average discharge 12 pressure will be determined and recorded. T.he flow rate will be compared with acceptance criteria established per Table IWF-3100-2. No lubrication level verification is required for this pump. L&orication is maintained under. our routine preventative maintenance program. No suction pressure instrumentation is required since this pressure can be calculated from sump i level measurements. The mechanical condition of the subject pumps will be determined from vibration data to be gathered quarterly. No bearing temperature instrumentation is installed.

McGUIRE - UNIT 1 O GENERAL RELIEF (III) TEST REQUIREMENT: Perfore trend analysis on category A and B valves by comparing stroke times with previous stroke times as described in IW-3417(a). BASIS: As described in NRC Generic Letter No. 89-04, Guidance on Developing Acceptance Inservice Testing Programs, comparing stroke times to a reference value is an acceptable alternative to comparing with the previous stroke time. This comparison will not allow the stroke times to gradually increase without requiring corrective action. ALTERNATE TESTING: Power operated valve stroke times will be compared to a reference stroke time value established when the valve is in good working order. Electric motor operated valves with reference values greater than 10 seconds will be compared to a 115% change from the reference value. Electric motor operated valves with reference values less than or equal to 10 seconds will be compared to a 125% change from the reference value. Other power operated valves with reference values greater than 10 seconds will be compared to a 125% change from the reference value. Other power operating valves with reference values less than or equal to 10 seconds will be compared to a 150% change from the reference value. If the stroke time for a valve is not within this acceptable range br. sed on reference values, the test frequency will be increased to once each month until corrective action is taken. The requirement of IW-3417(a) to compare stroke times to previous stroke times will not be followed. Any abnormal or erratic action will be reported. O New Page Revision 13
McGUIRE - UNIT 1 RELIEF / JUSTIFICATION: RR-NO3 f VALVE: IND-8, IND-23 i FLOW DIAGRAM: MC-1561-1. 0 j CATEGORY: C CLASS: B FUNCTION: Prevents reverse flow through the 110 Pumps TEST REQUIREMENT: Full stroke exercise quarterly. BASIS: IND-8 and 1ND-23 cannot be fully stroked during power operation since the only full flow path is into the RCS and the NO Pumps cannot overcome RCS presure. The ND Pump recire line is not large enough to accomodate full design flow. During cold shutdown the RCS expansion volume will not accomodate the flow required to full stroke these valves. ALTERNATE TESTING: Valves will be full stroke exercised at refueling and 's partial stroked quarterly. The opposite train valves will be tested closed during 33 quarterly pump testing except when the opposite train of ND is in service. O Revision 13

O-DUKE POWER COMPANY McGUIRE NUCLEAR STATION - UNIT 2 PUMP INSERVICE TESTING PROGRAM ASME SECTION XI, SUBSECTION IWP INTRODUCTION 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 Nuclear Regulatory Commission. A description of the proposed inservice testing program, as well as specific relief requests from code requirements determined to be impractical, is described in this submittal. NOTES: 1) IWP-6240(f) requires the signature of the person or persons responsible for conducting and analyzing the test. The dated initials of the person or persons responsible for conducting and analyzing the test may be used in place of a signature in the record of tests. Initials shall be construed as signatures to meet the intent of IWP. 2) IWP-4110 requires instrument accuracy to be within the limits of Table IWP-4110-1. For vibration, the acceptable instrument accuracy is 155 of full scale. Presently, the accuracy of the meter being used for displacement vibration measurements is 111%. Test instrumentation for velocity vibration measurements meets the instrument accuracy identified in General Relief Recuest I.38. Velocity and displacement vibration measurements are being measured currently. Displacement measurements will be dropped after velocity measurement 9 acceptance criteria is developed. 3) Af ter changing to velocity vibration measurements only, bearing temperature measurements will be dropped from our IST program. 4) Deleted O Rev 9 l

i i O !.3 The following are general request:; for relief from certain code requirements. (A) MMPS: All pumps included in the !$1 program. TEST REQUIREMEN1: Table IWP-3100-1 requires measuring static I suction pressure (Pi) prior to pump startup. i BAS!$ FOR RELIEF: This measurement ensures adequate NPSH is I available. Occasionally, pumps may be in i service supporting norinal plant operation. In these cases, NPSH requirements have already been verified and it is not required to shut i down an operating pump to measure static suation pressure. 1 ALTERNATE TESTING: For pumps operating at time of test, static suction pressure (Pi) will not be measured. l J i V O l 1 O
l' 1 (B) PUMPS: All pumps included in the IST program. TEST REQUIREMENT: IWP-3100 and IWP-3210 require vibration amplitude to be measured. IWP-3210 specifies the allowable ranges of vibration amplitude measurements. IWP-4110 requires the accuracy of vibration amplitude measurements to be +/-5% of full scale. IWP-4120 requires the full-scale range of vibration instrumentation to be three times the reference' value or less. IWP-4510 requires displacement vibration amplitude to be read at one specific location during each test. IWP-4520(b) requires the frequency response range of vibration instrumentation to be from one-half minimum speed to at least maximum pump shaft speed. BASIS FOR RELIEF: Experience has shown that measuring vibration as required by IWP is not the most effective way to determine the mechanical condttion of a pump. In order to better determine the mechanical condition of pumps, multiple vibration velocity masurements will be obtained/ evaluated and supplemented, when 9 necessary, with acceleration / displacement measurements and spectral analysis. In order to facilitate this testing, digital vibration instrumentation will be used. IWP does not provide adequate guidance / requirements for performing the better/ alternate testing. ALTERNATE TESTING: In lieu of the vibration requirements of IWP-3100 and IWP-3300, peak vibration velocity will be measured. In most cases, vibration velocity gives the best indication of machine mechanical condition. In lieu of IWP-4520(b) vibration instrumentation will be calibrated and vibration velocity will be measured over a range of 10 to 1000 Hz. (Measurements at other frequencies will be taken as necessary.) This is the range that the state of the art instrumentation used can be adequately calibrated over. This range will encompass most potential' noise contributors. O Rev. 9
=4-b In lieu of the vibration instrument accuracy N/ requirements of IWP-4110, vibration instrument accuracies will be within the limits specified below. These accuracies will be used because IWP does not specify accuracies for vibration l-velocity. These accuracies are the best that-l can reasonably be obtained from the state of the art instrumentation used. (The requirements of IWP allow vibration-inaccuracies of greater than +/-15% of reading.) Accelerometer: +/-5% of reading. (Due to the 4:1 rule, a lab l. uncertainty of +/-2.3% has to be added to the accelerometer uncertainty for a total / absolute accuracy statement of +/-7.3% of l reading.) Data Collector: +/-5% of full scale l~ (full scale is 1 volt) or +/-6% of velocity readings. (These are 9 total / absolute accuracies.) In lieu of the range requirements imposed on vibration instrumentation by IWP-4120, there will be no vibration instrumentation range requirement (digital vibration instrumentation is auto-ranging). It is not necessary to have a range requirement because the accuracies stated above and the readability of a digital gauge are not dependent upon-instrument range. In lieu of the vibration ranges specified in IWP-3210, the following ranges-shall be used. These ranges will be used because IWP does not i l specify ranges for vibration velocity. These ranges are based on current vibration standards (vibration severity charts).

O New Page - Rev. 9
l .f ] 1 ( (C) PUMPS: All pumps included in the IST program. O TEST REQUIREMENT: IWP-3100, IWP-3300 and IWP-3500 require the annual measurement of bearing temperature. BASIS FOR RELIEF: The yearly measurement of bearing temperature for umps does not provide any meaningful information. Several factors such as the temperature of the working fluid, the ambient temperature, and lubricant temperature and the size of the bearing housing will mask any-bearing condition change short of a catastrophic failure. Obtaining these measurements requires a minimum of one-half hour of pump operation to achieve stable bearing temperatures. The small probability of detecting bearing failure by temperature l measurement does not justify the additional pump operating time required to make the l measurement. ALTERNATE TESTING: Quarterly pump bearing vibration signatures will be used to evaluate pump mechanical ,l. condition and to detect bearing degradation. The velocity signatures provide a better indication of bearing performance since these measurements are not substantially affected by 9 l outside influences. ANSI /ASME OM-6 has dropped the IWP bearing stabilization requirement since i no real trendable data can be obtained. e O Rev. 9
I 1.4 The following Safety Class 2 and 3 Pumps (see Section I.2 for available Or instrumentation) will be tested in accordance with the intent of Subsection IWP of the ASME Code, except where relief requests have been written for specific requirements determined to be impractical as described below: (A) PUMPS: D/G Fuel Oil Transfer Pumps (2A, 28)- SAFETY CLASS: 3 FUNCTION: Diesel Generator Auxiliary Support TEST REQUIREMENTS: Test pumps in accordance with Subsection IWP BASIS FOR RELIEF: IWP does not provide appropriate provisions for testing positive displacement pumps. ALTERNATE TESTING: The Fuel Oil Transfer Pumps are internal gear positive displacement pumps. The performance curve for these pumps is relatively flat. Capacity of these pumps is independent of discharge pressure when operating properly and operating below the cracking pressure o? the pump internal relief valve. Discharge pressure will be measured for information purpsses, but will not be compared to any acceptanc.e criteria. Pumps will be tested by measuring level rise in the Fuel Oil Day-Tank and 8 converting this to'flowrate. Pump testing is between the level setpoints of the Fuel Oil Day Tank and this gives a run time of approximately 60-75 seconds. The flowtate (Q) will be compared to acceptance criteria established in accordance with Table IWP-3100-2 except the Acceptable Range has been widened and the High Alert Range increased to allow for level instrument fluctuations. Acceptable Range: 0.94 to 1.07 Qr Low Alert Range: 0.90 to 0.94 Qr High Alert Range: 1.07 to 1.10 Qr Low Required Action Range: <0.90 Qr High Required Action Range: >1.10 Qr These pumps are designed to produce a flowate of 22 gpe. The system design flowrate requirement for the pumps is 11 gpe. This difference provides a comfortable margin in the event a reference value is falsely established that would allow approximhtely 12% pump Rev. 8
fi degradation before requiring any action in V accordance with IWP. D/G Fuel 011 Storage Tank is monitored to maintain level required by McGuire Technical Specifications. This level ensures adequate l NPSH and no suction gauge is required. ~ No lubrication level verification is required for this pump. Lubrication is maintained under our' routine preventative maintenance program. The mechanical condition of the subject pumps will be determined from vibration data to be gathered quarterly. No bearirg temperature instrumentation is installed. ANSI /ASME OM-6 9 will not require bearing temoerature l-measurements. In addition, monthly Diesel Generator starting and loading (as required by McGuire Technical Specifications) will assess the hydraulic condition of the subject auxiliary pumps and demonstrates the capability of the individual components to perform their design function. l ,] O O Rev. 9
i (B) PUMPS: Safety Injection Pumps (2A, 28) SAFETY CLASS: 2 FUNCTION: To provide emergency core cooling in the event of a break in either the reactor coolant or steam system piping. TEST REQUIREMENT: IWP-3100 requires the resistanch cf the system to be varied until either the measured differential prescure or the measdred flow rate equals the corresponding reference value. 9 BASIS FOR RELIEF: The previous edition of Section XI specified that in a fixed esistance system, either DP or Q was to be measured, not both. 10CFR, Section 50.55a(g)(4) states that design provisions are excluded from the requirement to upgrade to subsequent editions of Section XI. ALTERN5ff TESTING: The Safety Injection Pumps are tested using fixed resistance flowpaths with flow' indication available. Since no flow adjustment is available, a flow will be recorded but will not be used for comparison to any reference values. O 9 Rev. 9
(C) PUMPS: Residual Heat Removal Pumps (2A, 28) SAFETY CLASS: 2 FUNCTION: To remove heat energy from the core and Reactor Coolant System during cooldown and refueling operations. Also, utilized as part of Safety Injection System and Containment Spray System during an accident' condition. TEST REQUIREMENT: IWP-3100 requires the resistance of the system to be varied until either the measured differential pressure or the measured flow rate equals the corresponding reference value.. BASIS FOR RELIEF: The previous edition of Section XI specified that in a fixed resistance system, either OP or Q was to be measured, not both.
- 10CFR, Section 50.55a(g)(4) states that design provisions are excluded from the requirement to upgrade to subsequent editions of Section XI.
ALTERNATE TESTING: The Residual Heat Removal Pumps are tested using fixed resistance flowpaths with flow indication available. Since no flow adjustment is available, a flow will be recorded but will j. not be used for comparison to any reference-
- values, t

4 t (D) PUMPS: Centrifugal Charging Pump (2A, 28) SAFETY CLASS: 2 FUNCTION:- To supply reactor coolant inventory in the Volume Control Tank or Refueling Water Storage 9 Tank to the reactor coolant system.. TEST REQUIREMENT: Table IWP-3100-1 requires measuring differential pressure (DP) and flow rate (Q). BASIS FOR RELIEF: The previous edition of Section XI specified that in a fixed resistance system, either DP or Q was to be measured, not both.
- 10CFR, Section 50.55a(g)(4) states that design provisions are excluded from the requirement to upgrade to subsequent editions of Section XI.
ALTERNATE TESTING: The Centrifugal Charging Pumps are tested quarterly using fixed resistance flow paths with no flow indication provided. To supplement this quarterly testing, Centrifugal Charging Pump testing at emergency design flow conditions will be performed during refueling outages (starting in 1990). l l O Rev. 9
1 + ..=. .(E) PUMPS: D/G Room Sump Pumps (2A2, 2A3, 2B2, 283) SAFETY CLASS: 3 FUNCTION: Water removal from Diesel Generator Rooms TEST. REQUIREMENT: -Test pumps in accordance with Subsection IWP. BASIS FOR RELIEF: The D/G Room Sump Pumps are vertical pumps tested by filling the D/G Room Sump and pumping the sump down. No stable system conditions can_ j be obtained due to the continuous decrease in sump level. No suction pressure, flow, bearing temperature, or lubricant level instrumentation is available. ALTERNATE TESTING: The 0/G Room Sump Pumps will be tested for greater than or equal to emergency design flow 1 by: (1) Filling the sump and recording level. (2) Pumping down the sump and recording both level and pump down time. l An average flow rate will be determined from l the time it takes to pump a known volume from t the sump. Pumping down the sump takes approximately 60 seconds. An average discharge 8 pressure will be determined and recorded.. The flow rate will be compared with acceptance. criteria established per Table IWP-3100-2. No lubrication level verification is required for this pump. Lubrication is maintained under our routine preventative maintenance program, i No suction pressure instrumentation is required since this pressure can be calculated from sump level measurements. The mechanical condition of the subject pumps will be determined from vibration data to be l gathered quarterly. No bearing temperature I instrumentation is installed. ANSI /ASME OM-6 9 will not require bearing temperature measurements. i l l= Rev. 9 l
i.1 n. (F) The Standby Makeup Pump is not safety related and does not receive eastgency power. It is required to be tested by McGuire Technical Specifications. Therefore, the relief request and alternate-testing -nothod is described below. PUMPS: Standby Makeup Pump No. 2 SAFETY CLASS: N/A FUNCTION:. To supply makeup water to the Reactor Coolant system if the normal system is unavailable. TEST REQUIREMENT: Test pump in accordance with IWP (Technical Specification requirement). BASIS FOR RELIEF: IWP does not provide appropriate provisions for testing positive displacement pumps. ALTERNATE TESTING: The Standby Makeup Pump is a single speed reciprocating positive displacement purp. Pump will be verified capable of performing its design function by testing for design flowrate (>26 GPM) and pressure (>2485 PSIG). The design system pressure requirement will be simulated using a throttle valve. The discharge pressure is a function of the system requirement and is independent of suction pressure. The pump is located sufficiently below the fuel pool to assure that adequate NPSH is available and no suction guage is required. The mechanical condition of the pump will be determined from vibration data to be gathered quarterly. No bearing temperature instrumentation is installed. ANSI /ASME OM-6 .9 will not require bearing temperature measurements. O Rev. 9

J 4,. McGUIRE - UNIT 2 l O GENERAL RELIEF (III) j 4 TEST REQUIREMENT: Perfom trend analysis on category A and B valves by comparing stroke times with previous stroke times as described in IW-3417(a). BASIS: As described in NRC Generic Letter No. 89-04, Guidance on Developing Acceptance Inservice Testing Programs, comparing stroke times to a reference value is an acceptable alternative to comparing with the previous stroke time. This comparison will not allow the stroke times to gradually increase without requiring corrective action. ALTERNATE TESTING: Power ope' rated valve stroke times will be compared'to a reference stroke time value established when the valve is in good working order. Electric motor operated valves with reference values greater than 10 seconds will be compared to a 115% change from the-reference value. Electric motor operated valves with reference values less than or equal to 10 seconds will be compared to a 125% change from the reference value. Q Other power operated valves with reference values. Q greater than 10 seconds will be compared to a 125% change from the reference value. Other power operating valves with reference values'less than or equal to 10 seconds will be compared to a 150% change' from the reference value. If the stroke time for a valve is not within this acceptable range based on reference values, the test frequency will be increased to once each month until corrective action is taken. l The requirement of IW-3417(a) to compare stroke times l to previous stroke times will not be followed. Any l abnormal or erratic action will be reported. New Page Revision 9
