1.0 IST PROGRAM INTRODUCTION 1.1 GENERAL This document describes the Inservice Testing (IST) Program for Edwin I. Hatch Nuclear Plant, Units 1 and 2. The below table identifies important dates associated with the Inservice Testing Program.

Hatch Unit 1 Hatch Unit 2 Construction Permit 09-30-1969 12-27-1972 Commercial Operation 12-31-1975 09-05-1979 1st 10 Year Interval 01-01-1975 to 09-06-1979 to 12-31-1985 12-31-1985*

2nd 10 Year Interval 01-01-1986 to 01-01-1986 to 12-31-1995 12-31-1995 3rd 10 Year Interval 01-01-1996 to 01-01-1996 to 12-31-2005 12-31-2005 01-01-2006 to 01-01-2006 to 4th* 10 Year Interval 12-31-2015 12-31-2015 01-01-2016 to 01-01-2016 to 5th 10 Year Interval 12-31-2025 12-31-2025

Hatch Unit 2 was optionally updated at the same time as Unit 1 for the 2nd 10 Year Interval in order to place both units on the same edition of the code.

The edition of 10 CFR 50.55a current on January 1, 2015, was used to determine the applicable Code(s) for this program update. This 10 CFR 50.55a edition identified the ASME OM Code, 2004 Edition with Addenda through 0Mb 2006 (as referenced in §50.55a(b)(3)), as the applicable Code for pump and valve testing.

This document includes inservice testing requirements for pumps and valves. The inservice testing of dynamic restraints (snubbers) Subsection ISTD of the OM Code is not included in this program plan. The Snubber Program is currently documented and maintained under the lnservice Inspection Program.

NUREG-1482, Guidelines for Inservice Testing at Nuclear Power Plants, Revision 2 was used, to the extent practical, for guidance in the development of this program.

introgen.doc 1-1 Version 1.0

1.2 EFFECTIVE DATE The 1ST Program, for the 5th 10 year interval will become effective on January 1, 2016 and will be utilized through December 31, 2025 unless the federal regulations are revised otherwise.

1.3 SCOPE This document is a description of the 1ST Program to be implemented for Units 1 and 2 at Plant Hatch. This document describes only the 1ST surveillance testing applicable to pumps and valves included in the program.

1.4 COMPONENT UPGRADING Plant components have been reviewed to determine the appropriate classification for inservice testing. Regulatory Guide 1.26 (September 197 4) was used for guidance in determining component classifications.

Note that the classification of pumps and valves as ASME Class 1, 2, or 3 equivalents for this program does not imply that the components were designed in accordance with ASME requirements. Pump and valve design remains as stated in the FSAR.

1.5 SUBSEQUENT PROGRAM REVISIONS It is anticipated that this Program will be reviewed again near the end of the 120 month interval and compared to a later NRC approved edition and addenda of the ASME Code applicable for 1ST. At that time, the program will be modified, if required, to comply to the extent practical with the later code edition. Any additional relief requests for alternative testing or impractical requirements will be submitted in accordance with the applicable federal regulations.

1.6 RESPONSIBILITY Southern Nuclear Operating Company (SNC), as Owner, bears the overall responsibility for the implementation of the inservice testing activities contained in this program per OM Code, ISTA 1500.

1.7 RECORDS Records and documentation of information and testing results, which provide the basis for evaluation and which facilitate comparison with results from previous and subsequent tests, will be maintained and available for the active life of the component or system in accordance with OM Code, ISTA 9000.

introgen.doc 1-2 Version 1.0

1.8 METHODS OF TESTING The method of testing applicable to pumps and valves is listed adjacent to each component identification in the pump and valve test tables contained in this program plan. The OM Code does not stipulate any specific training/certification requirements for personnel involved in pump and valve testing. At Plant Hatch, all pump and valve testing is performed by operations, maintenance or engineering department personnel who have been trained to perform specific testing tasks.

1.9 STANDARDS FOR TESTING EVALUATION The acceptance criteria applicable for each pump and valve to be tested have been developed in accordance with OM Code requirements as modified by any applicable relief requests. Acceptance criteria are not provided in the IST Program, but are provided in the IST Basis and the applicable surveillance testing procedures which are available for review at the plant site.

3.0 INSERVICE TESTING OF PUMPS 3.1 GENERAL This IST program was developed to comply with the requirements of 10 CFR 50.55a(f) which delineate the testing requirements for ASME Class 1, 2, and 3 pumps. The Code of record required by 10 CFR 50.55a(b) (3) for 5th Interval pump IST is the ASME OM Code-2004 Edition with Addenda through OMb-2006. The supplemental guidance of NRC NUREG-1482, Revision 2 has been applied to the extent practicable. For pumps which are within the scope of IST, as stipulated in 10 CFR 50.55a, where specific Code requirements cannot be met, relief has been requested from the specific Code requirements.

As required by OM Code, ISTB-1300, pumps within the scope of this program shall be categorized as either Group A or Group B pumps.

Group A pumps are defined as pumps that are operated continuously or routinely during normal operation, cold shutdown, or refueling. operation.

Group B pumps are defined as pumps in standby systems that are not operated routinely except for testing.

Group A and Group B pump testing is required quarterly. In addition, to the quarterly Group A or Group B pump tests, the OM Code imposes a biennial Comprehensive Pump Test and a Preservice Pump Test for pumps that are overhauled or replaced. The IST Program Pump Tables list the parameters measured during Group A, Group B, and Comprehensive Pump Testing.

Preservice Testing is equivalent to Comprehensive Pump Testing, except Preservice Testing requires the development of a five point pump curve for centrifugal and vertical line shaft pumps in which flow and differential pressure is measured. Vibration measurements are only required to be taken at the reference value(s).

The Preservice Test for Standby Liquid Control pumps is equivalent to the Comprehensive Pump Test.

3.2 SCOPE Safety-related ASME Class 1, 2, and 3 pumps meeting the criteria of the ASME OM Code and falling under the Regulatory Position of Regulatory Guide 1.26 (September 1974) are included within the scope of this program. Special scope features of the Hatch IST Program are discussed below.

It is recognized that 10 CFR 50 Appendix A, GDC-1, and Appendix B, Criterion XI intend that all pumps necessary for safe operation of the plant be tested to demonstrate that they will perform satisfactorily in service. This testing is to be performed to a level commensurate with the function of the pump. This testing is generally performed per the requirements of the plant Technical Specifications or other requirements. In cases where Code requirements are impractical for certain pumps, or an alternate testing method is considered an improvement over OM Code requirements, a relief request has been developed. Pump relief requests are located under a separate tab.

pumptst.doc 3-1 Ver. 1.0 .

3.2 Scope (Cont.)

No credit is taken in any of the accident analyses for the RCIC system (re: NRC SER dated 8/21/97). Therefore, the RCIC pumps have been included in this Program as augmented components to provide a readily accessible, documented method of testing. This testing will be performed in a manner similar to the OM Code testing and should adequately detect degradation.

The Diesel Generator Fuel Oil Transfer Pumps are not ASME classed components and are not included within the scope of Regulatory Guide 1.26 (September 1974). These pumps have been included in this Program as Augmented components to provide a readily accessible, documented method of testing. This testing will be performed in a method similar to that found in the OM Code, and should adequately detect degradation in these particular pumps.

Testing methods and test intervals for Augmented components are established and justified within the IST Program. Where deviations from strict Code compliance exists, the IST Engineer is responsible for ensuring the overall adequacy of the testing. Obtaining relief from the NRC for such deviations is not required for Augmented components.

The Spent Fuel Pool Cooling Pumps have not been included in this Program because they are not safety-related. Credit is taken in the FSAR for Plant Service Water as the safety-grade makeup source to the spent fuel pool with the RHR system available as a safety-grade backup cooling source.

The Core Spray Jockey Pumps and associated valves have not been included in this Program because they are not considered to have an active safety-related function as described in ISTA-1100. The valves which form the boundary between the Core Spray Jockey sub-system and the Core Spray/ Residual Heat Removal systems are included in IST scope.

PUMP TEST NOTES

1. Deleted.

2. Differential pressure for this pump is calculated by measuring the discharge pressure and the river level and computing the required pressure. The Pump 1ST Basis and the surveillance test procedure include the equation used to calculate the differential pressure.

This measurement method is acceptable per ISTB-3520 and NUREG-1482, Rev.2, paragraph 5.5.3.

3. As discussed in the "SCOPE" section of this program document (para. 3.2), the RCIC system is not required to be included in the 1ST Program. However, it is desirable to maintain the system in a documented testing program. Testing will be performed in a manner as close as practical to OM Code test requirements. (re: NRC SER dated 8/21/97)

4. RCIC Pump suction pressure gauges, 1(2)E51-PI-R604, exceed the range limit of 3 times the reference value. However, the gages are calibrated to +/-1 % full scale accuracy which results in the final variance being within the maximum allowable tolerance of the OM Code (i.e. 1.62 psig (.02 X 81) versus 1 psig (.01 X 100) for Unit 1 and 1.44 psig (.02 X 72) versus 1 psig (.01 X 100) for Unit 2). *

5. RCIC Pump flow instruments, 1(2)E51-FI-R612, exceed the maximum Code allowable total loop accuracy, however, the indicator used has a full scale range less than the Code allowable. The maximum variance allowed by the Code would be 24 gpm (.02 X 1200) whereas the acttial maximum variance is 10.6 gpm (.0212 X 500). Therefore, the actual accuracy of the instrument loop is better than that required by the Code.

6. This system does not fall within the scope requirements of the ASME OM Code as implemented by 10 CFR 50.55a (i.e. not ASME Class 1, 2 or 3), is not covered by the Regulatory Position of Regulatory Guide 1.26 (September 1974), and was not designed to facilitate performance of OM Code type pump testing. Therefore, it is only included in this program document to provide a readily accessible, controlled mechanism for testing. As discussed in Section 3.2 of this document, testing will be performed in a manner similar to that of the OM Code, and such testing should adequately detect degradation.

7. Instrumentation was not provided to measure flow. A portable ultrasonic type instrument is used to measure flowrate. The inlet pressure is calculated and the discharge pressure is throttled to set the reference differential pressure and then the flowrate is measured. If the flowrate decreases below a specified value, which is determined taking into account the repeatability of the flow measuring device and the design parameters of the pump, the pump will be declared inoperable.

PUMP TEST NOTES Notes (cont.)

8. The Diesel Generator Fuel Oil Transfer Pumps are located inside the storage tanks with the motor and pump coupling area located above the tank. This arrangement provides inherent deficiencies for detection of degradation through vibration testing. Therefore, best effort motor vibration measurements will be taken to assist in the detection of degradation in the pumps.

9. Operational readiness is confirmed by numerous Technical Specifications surveillance requirements. The frequency of these tests vary from monthly to each operating cycle.

Therefore, flowrate and vibration monitoring every 6 months should adequately detect any degradation detrimental to operational readiness.

10. RCIC pump discharge pressure indications, 1(2)E51-PI-R601, do not satisfy the OM Code requirement for full scale range (i.e., 0-1500 psig versus 0-1800 psig). However, the indicators have a sufficient margin to ensure accurate and repeatable measurement of pump discharge pressure.

ISTPROGRAM PROPOSED ALTERNATIVE IN ACCORDANCE WITH 10 CFR 50.55a(z)(l)

RR-P-3 PLANT/UNIT: Edwin I Hatch Nuclear Plant/Unit 1 and 2.

INTERVAL: 5th Interval beginning January 1, 2016 and ending December 31, 2025.

COMPONENTS 1Ell-C002A,B ,C,D (Centrifugal Pumps) - Group A AFFECTED: 2Ell-C002A,B ,C,D (Vertical Line Shaft Pumps) - Group A CODE EDITION ASME OM Code-2004 Edition with Addenda through OMb-2006 AND ADDENDA:

REQUIREMENTS: ISTB-3510(b) (1) requires that the full-scale range for each analog instrument shall not be greater than three times the reference value. The Residual Heat Removal (RHR) system pump discharge pressure indicators 1 (2)El 1-PI-R003A-D exceed this Code allowable range limit.

REASON FOR This alternative is a re-submittal of NRC approved 4th Interval reiief request RR-REQUEST: P-3 that was based on the ASME OM Code-2001 Edition. This 5th Interval request for relief, RR-P-3, is based on the ASME OM Code - 2004 Edition with Addenda through OMb-2006. There have been no substantive changes to this alternative or to the basis for use, which would alter the previous NRC Safety Evaluation conclusions. (See References for SER date and TAC numbers associated with RR-P-3).

The original installed instrumentation associated with these pumps was not designed with the instrument range limits of OM Code ISTB-3510(b) (1) taken into consideration. The actual instrument ranges are itemized below.

INSTRUMENT RANGE REF ALLOWED ACCURACY VALUE RANGE*

1Ell-PI-R003A -D 0-600 psig 171-185 psig 0-513 psig +/-0.5%

2Ell-PI-R003A -D 0-600 psig 180-195 psig 0-540 psig -+/-0.5%

- Allowed Range corresponds to 3 times the lowest reference value 7-4 Version 1.0

RR-P-3 (Cont.)

PROPOSED Hatch proposes to use the existing installed instrumentation during Group A pump ALTERNATIVE testing. Even though 1(2)Ell-PI-R0 03A-D exceed the Code allowable range limit AND BASIS: of three times the reference value, this additional gage range coupled with the better-than-Code-required accuracy of 0.5% results in only a 3 psi (600 x 0.005) maximum variance compared with the Code allowable variance of 10.26 psi (513 x 0.02). -,

Using other (temporary) instrumentation during Group A testing is not justifiable considering the difficulty and dose associated with such a requirement. The installed pressure indicators will provide data that is sufficiently accurate to allow assessment of pump condition and to detect degradation during the performance of the Group A 1ST pump testing. Highly accurate M&TE, which meets all Code requirements, will be installed during Comprehensive and Preservice testing.

The above proposed alternative provides an acceptable level of quality and safety since the variance in the actual test results is less than the maximum variance allowed by the Code. Based on the determination that the use of installed instrumentation provides an acceptable level of quality and safety, this proposed alternative should be granted pursuant to 10 CFR 50.55a(z) (1).

REASON FOR This alternative is a re-submittal of NRC approved 4th Interval relief request RR-REQUEST: P-4 that was based on the ASME OM Code-2001 Edition. This 5th Interval request for relief, RR-P-4, is based on the ASME OM Code-2004 Edition with Addenda through OMb-2006.

RR-P-4 (Cont.)

1 (2)El 1-FI-R608A(B) exceed the Code allowable full scale range limit of three times the reference value. The design of the indicator range includes consideration for LPCI flow rate (17,000 gpm for two pumps), whereas the minimum 1ST pump flow rate reference value is 7,700 gpm for Unit 1 and Unit 2. The Code maximum allowable inaccuracy in measured flow rate would be 462 gpm (i.e., .02 x 23,100) for Units 1 and 2, whereas the actual maximum inaccuracy in measured flow is 218 gpm (i.e., .0087 x 25,000) for both Unit 1 and Unit 2. Therefore, the actual accuracy of the installed flow indicators is better than required by the Code, thus the range of the indicator exceeding the Code limit of three times the reference value is of no consequence.

PROPOSED Hatch proposes to use the existing installed instrumentation for Group A, ALTERNATIVE Comprehensive Pump, and Preservice Testing.

AND BASIS:

Even though 1(2)Ell-FI-R608A& B exceed the Code allowable range limit of three times the reference value, the overall loop accuracy is better than required by the Code. Therefore, the measured parameter is more accurately displayed than the Code requires. The above proposed alternative is acceptable since the variance in the actual test results is more conservative than that allowed by the Code.

Based on the determination that this alternative provides an acceptable level of quality and safety, the proposed alternative should be granted pursuant to 10 CFR 50.55a(z)(l).

RR-P-5 PLANT/UNIT: Edwin I Hatch Nuclear Plant/Unit 1 and 2.

INTERVAL: 5th Interval beginning January 1, 2016 and ending December 31, 2025.

COMPONENTS lEl l-COOlA,B,C,D (RHRSW Vertical Line Shaft Pumps) - Group A AFFECTED: 2El 1-C001A,B,C,D (RHRSW Vertical Line Shaft Pumps) - Group A 1P41-C001A,B,C,D (PSW Vertical Line Shaft Pumps) - Group A 2P41-C001A,B,C,D (PSW Vertical Line Shaft Pumps) - Group A CODE EDITION ASME OM Code-2004 Edition with Addenda through OMb-2006 AND ADDENDA:

REQUIREMENTS: ISTB-3540(b) requires that vibration measurements on vertical line shaft pumps be taken on the upper motor-bearing housing in three approximately orthogonal directions, one of which is the axial direction.

REASON FOR This alternative is a re-submittal of NRC approved 4th Interval relief request RR-REQUEST: P-5 that was based on the ASME OM Code-2001 Edition. This 5th Interval request for relief, RR-P-5, is based on the ASME OM Code-2004 Edition with Addenda through OMb-2006. There have been no substantive changes to this alternative, to the OM Code requirements or to the basis for use, which would alter the previous NRC Safety Evaluation conclusions. (See References for SER date and TAC numbers associated with RR-P-5).

The Code required vibration measurements on the upper motor bearing housing on these vertical line shaft pumps are impractical because of the following reasons.

1. Plant design did not include permanent scaffolding or ladders which provide access to the top of the motors for the subject pumps.

2. Physical layout of the pumps and interference with adjacent components does not allow for the installation of temporary scaffolding or ladders which are adequate and safe for routine use.

3. There is a thin cover plate bolted to the top-center of each motor which prevents measurements in line with the motor bearing. Measurement on the edge of the motor housing would be influenced by eccentricity and may not be representative of actual axial vibration.

4. Special tools (extension rod) for placing the vibration transducers are not practical because placement would not be sufficiently accurate for trending purposes.

7-6 Version 1.0

RR-P-5 (Cont.)

5. Research within the industry has indicated that vibration monitoring of vertical line shaft pumps has been of limited benefit for detecting mechanical degradation due to problems inherent with pump design. The OM Code imposes more stringent hydraulic acceptance criteria on these pumps than for centrifugal pumps. These more stringent hydraulic acceptance criteria place more emphasis on detection of degradation through hydraulic test data than through mechanical test data.

PROPOSED Vibration measurements will be taken in three orthogonal directions, one of which is ALTERNATIVE in the axial direction in the area of the pump to motor mounting flange when AND BASIS: conducting Group A, Comprehensive Pump and Preservice Testing. This is the closest accessible location to a pump bearing housing and this location is easily and safely accessible for test personnel which should ensure repeatable vibration data and should provide readings which are at least as representative of pump mechanical condition as those required by the Code.

The above proposed alternative provides reasonable assurance of operational readiness since vibration measurements will be taken in three orthogonal directions at the pump to motor mounting flange which will provide information as to the mechanical integrity of the pump. Based on the determination that compliance with the Code requirement results in a hardship without a compensating increase in the level of quality and safety, this proposed alternative should be granted pursuant to 10 CFR50.55a(z) (2).

The indicators used have full scale ranges less than that allowed by the Code. The maximum code allowable variance in measurement is 16.96 psig (.02 x 847.8) for Unit 1 and 20.1 psig for Unit 2 (.02 x 1005). Even considering the lower reference values of 273 psi and 332.5 psi respectively, the code allowable variances would still be met. By using an indicator with a range less than the allowed limit, the actual maximum variance is 10.5 psig (.021 x 500) which is more accurate than required by the Code. Therefore, the actual accuracy of the instruments is within the Code allowable as specified in Table ISTB-3510-1 for a Group B pump test.

PROPOSED None, the installed instruments are more accurate than required by the Code for the ALTERNATIVE range of application when performing a quarterly Group B pump test. Temporary AND BASIS: pressure instruments that meet code requirements will be used during Comprehensive Pump and Preservice Testing.

The above proposed alternative provides an acceptable level of quality and safety since the variance in the actual test results is less than the maximum variance allowed by the Code. Based on the determination that the use of installed instrumentation provides an acceptable level of quality and safety, this proposed alternative should be granted pursuant to 10 CFR 50.55a(z) (1).

REQUIREMENTS: ISTB-3540(b) requires that vibration measurements on vertical line shaft pumps be taken on the upper motor-bearing housing in three approximately orthogonal directions, one of which is the axial direction.

REASON FOR This alternative is a re-submittal of NRC approved 4th Interval relief request RR-P-9 REQUEST: that was based on the ASME OM Code-2001 Edition. This 5th Interval request for relief, RR-P-9, is based on the ASME OM Code-2004 Edition with Addenda through OMb-2006. There have been no substantive changes to this alternative, to the OM Code requirements or to the basis for use, which would alter the previous NRC Safety Evaluation conclusions. (See References for SER date and TAC numbers associated witp RR-P-9).

The Code required vibration measurements on the upper motor-bearing housing on this Unit 2 Standby Diesel Generator Service Water vertical line shaft pump are impractical because of the following reasons.

1. The motor has a cooling fan mounted at the top which is.attached to the rotating shaft. The fan is protected by a relatively thin cover plate which prevents access to the motor housing for vibration measurements. Removing the cover does not provide for transducer placement since the rotating fan would still be in the way.

2. Research within the industry has indicated that vibration monitoring of vertical .

line shaft pumps has been of limited benefit for detecting mechanical degradation due to problems inherent with pump design. The OM Code imposes more stringent hydraulic acceptance criteria on these pumps than for centrifugal pumps. These more stringent hydraulic acceptance criteria place more emphasis on detection of degradation through hydraulic test data than through mechanical test data.

7-10 Version 1.0

RR-P-9 (Cont.)

PROPOSED Vibration measurements will be taken in three orthogonal directions, one of which is ALTERNATIVE in the axial direction in the area of the pump to motor mounting flange. This is the AND BASIS: closest accessible location to a pump bearing housing and this location is easily accessible for test personnel which should ensure repeatable vibration data and should provide readings which are at least as representative of pump mechanical condition as those required by the Code.

Therefore, application of the OM Code hydraulic testing criteria along with radial and axial vibration monitoring in the area of the pump to motor mounting flange should provide adequate data for assessing the condition of the subject pumps and for monitoring degradation. This request is only applicable to Comprehensive Pump and Preservice Testing. The above proposed alternative provides reasonable assurance of operational readiness since vibration measurements will be taken in three orthogonal directions at the pump to motor mounting flange which will provide information as to the mechanical integrity of the pump. Based on the determination that compliance with the Code requirements results in a hardship without a compensating increase in the level of quality and safety, this proposed alternative should be granted pursuant to 10 CFR50.55a(z)(2).

REQUIREMENTS: ISTB-3520(b) requires that differential pressure be determined by the difference between the pressure at a point in the inlet pipe and the pressure at a point in the discharge pipe if a direct indicating instrument is not provided.

REASON FOR This alternative is a re-submittal ofNRC approved 4th Interval relief request RR-P-REQUEST: 11 that was based on the ASME OM Code-2001 Edition. This 5th Interval request for relief, RR-P-11, is based on the ASME OM Code-2004 Edition with Addenda through OMb-2006. There have been no substantive changes to this alternative, to the OM Code requirements or to the basis for use, which would alter the previous NRC Safety Evaluation conclusions. (See References for SER date and TAC numbers associated with RR-P-11).

The RHR and CS pumps are aligned to the suppression pool (torus) during all modes of normal plant operation. The installed suction pressure gauges do not meet Code requirements. Suction pressure to these pumps is primarily a function of suppression pool level, which is controlled within a 4 inch range, and this results in a virtually constant suction pressure. IST is performed utilizing a full flow test line which circulates water to and from the suppression pool.

The Plant's Technical Specifications require that the suppression pool be maintained within a narrow range of level, temperature, and internal pressure during plant operation which results in a suction pressure of approximately 5 psig. The Unit 1 and 2 Technical Specification operability limits for the suppression pool are itemized below:

Level 2:: 146" & ::S 150" Internal Pressure :S 1.75 psig Water Temperature :S I00°F 7 - 12 Version 1.0

RR-P-11 (Cont.)

REASON FOR These Technical Specification operability limits for the suppression pool result in a REQUEST {cont.): maximum difference in calculated pump suction pressure of< 2 psig.

This 2 psig variance (dPi) is insignificant in relation to nominal discharge pressure and the calculation of differential pressure (dP = Po-Pi) when considering the Group A pump test acceptable operating range (i.e., 95-110% for vertical line shaft pumps from Table ISTB-5221-1 and 90-110% for centrifugal pumps from Table ISTB-5121-1) and the allowable+/- 2% instrument accuracy from Table ISTB-3510-1; or when considering the Group B pump test acceptable operating range (i.e., 90-110%

for centrifugal and vertical line shaft pumps from Table ISTB-5121-1 and Table ISTB-5221-1) and the allowable+/- 2% instrument accuracy from Table ISTB-3510-

1. Therefore, direct suction pressure measurement for differential pressure derivation provides no added benefit for determining pump operational readiness or for monitoring pump degradation.

This summary confirms that the RHR and Core Spray pump's suction pressures are consistent and are relatively insignificant in comparison with the pumps' discharge pressure.

One time occurrence only.

The permanently installed pump suction pressure gages encompass a wider range of pressures than does 1ST and thus exceed the OM Code allowable range limit (3 times the reference value). The installed RHR pump gages must account for the pressure experienced with the RHR loop in the shutdown cooling mode of operation. The installed CS pump gages must account for the pressure experienced with the CS suction aligned to the Condensate Storage Tank. Therefore, a temporary test gage which satisfies the Code range limits would have to be installed each time that 1ST is required.

Applying a constant pump suction pressure, when calculating differential pressure, will allow the Group A and B testing to be performed with the installed pressure gages, thus lessening the burden on operations personnel responsible for the testing.

Since temporary test gages are required to be calibrated both prior to and after usage, it also eliminates the possibility of invalidating test data due to a gage being damaged during transportation, installation or removal.

Mechanical degradation of centrifugal pumps which experience significant differences in suction (inlet) pressure would be indicated by changes in the differential pressure. However, for these pumps, the suction pressure variance is insignificant in comparison to the developed head (pressure).

Therefore, monitoring discharge pressure and calculating differential pressure assuming a constant 5 *psig suction pressure provides an adequate method to determine operational readiness and detect potential degradation.

7 -12b Version 1.0

RR-P-11 (Cont.)

PROPOSED Pump suction pressure will be assumed to be 5 psig based on a review of several ALTERNATIVE years of IST data which support suction pressure being virtually constant when AND BASIS: performing Group A and Group B testing. During these tests pump differential pressure will be calculated by measuring pump discharge pressure and subtracting 5 psig. This value will then be compared to the corresponding reference value. The acceptance criteria of Tables ISTB-5121-1 and ISTB-5221-1 will be applied for assessing pump operational readiness and for monitoring potential pump degradation during the applicable Group A or Group B pump test. This testing method meets the intent of the Code for monitoring pump operational readiness and degradation, and relieves the Licensee of the burden associated with the use of temporary test gages.

This request is not applicable to Comprehensive Pump or Preservice Testing.

The above proposed alternatiye provides an acceptable means of evaluating pump performance without a substantial decrease in the ability to monitor operational readiness. Based on the determination that compliance with the Code requirements, results in a hardship or unusual difficulty without a compensating increase in the level of quality and safety, this proposed alternative should be granted pursuant to 10 CFR 50.55a(z)(2). .

REQUIREMENTS: ISTB-3510(b)(l) requires that the full-scale range of analog instruments shall not be greater than three times the reference value, and Table ISTB-3510-1 requires an accuracy of+/- 2% full scale.

There have been no substantive changes to this alternative, to the OM Code requirements or to the basis for use, which would alter the previous NRC Safety Evaluation conclusions. (See References for SER date and TAC numbers associated with RR-P-12).

The flowrate for the Unit 2 Standby Diesel Generator Service Water (SDSW) pump is determined by measuring the differential pressure (dp), in inches of water, across a flow element and then using the vendor correlation chart to convert dp to flowrate in gallons-per-minute (gpm). The dp indicator (2P41-R383) has a full-scale range of -

178 inches of water to + 178 inches (356 inches total range) of water, which is greater than three times the reference value, and is calibrated to+/- 4 inches of water (i.e.,+/- 1.125% of full-scale). The indicator has a range which allows measurement of the flowrate in either direction across the flow element, thus the negative and positive scale ranges. The vendor supplied dp to flow correlation chart has a range of 50 - 145 inches of water which corresponds to a flowrate range of 500 - 850 gpm.

The reference flow for this pump is 707 gpm which corresponds to 100 inches of water. The OM Code would allow a full-scale range of O- 300 inches of water (i.e., 3 X 100) and a calibration accuracy of+/- 6.0 inches of water (i.e., 0.02 X 300).

The combined range and accuracy of the installed instruments is within the maximum allowable ofISTB-3510(b)(l) and Table-3510-1. The maximum Code allowable dp variance would be+/- 6.0 inches of water whereas the actual dp variance is +/- 4.0 inches of water. Therefore, use of the existing dp indicators and the vendor correlation chart provides flowrate measurements for IST that are at least as accurate as required by the OM Code.

The basis of the request is that the proposed alternative would provide an acceptable level of quality and safety. Specifically, this alternative is requested for all inservice testing of IST Program pumps listed in this Relief Request.

For pump testing, there is difficulty adjusting system throttle valves with sufficient precision to achieve exact flow reference values during subsequent IST exams.

Section ISTB of the ASME OM Code does not allow for variance from a fixed reference value for pump testing.

However, NUREG-1482, Revision 2, Section 5.3, acknowledges that certain pump system designs do not allow for the licensee to set the flow or pressure at an exact value because of limitations in the instruments and controls for maintaining steady flow.

ASME OM Code Case OMN-21 provides guidance for adjusting reference flow/pressure to within a specified tolerance during Inservice Testing. The Code Case states "It is the opinion of the Committee that when it is impractical to operate a pump at a specified reference point and adjust the resistance of the system to a specified reference point for either flow rate, differential pressure or discharge pressure, the pump may be operated as close as practical to the specified reference point with the following requirements. The Owner shall adjust the system resistance to as close as practical to the specified reference point where the variance from the 7 -14a Version 1.0

RR-P-13 (Cont.)

reference point does not exceed + 2% or - 1% of the reference point when the reference point is flow rate, or + 1% or - 2% of the reference point when the reference point is differential pressure or discharge pressure. The NRC also discusses this ASME Code change in NUREG-1482, Revision 2, Section 5.3.

PROPOSED Hatch seeks to perform future Pump Inservice Testing in a manner consistent ALTERNATIVE with the_ requirements as stated in ASME OM Code Case OMN-21. Specifically, AND BASIS: testing of all centrifugal pumps identified in this Relief Request will be performed such that flow rate is adjusted as close as practical to the reference value and within proceduralized limits of +2% / -1 % of the reference value. For positive displacement pumps the discharge pressure will be adjusted as close as practical to the reference value and within proceduralized limits of+ 1% / -2% of the reference value.

Hatch plant operators will still strive to achieve the exact test reference values during testing. Typical test guidance will be to adjust flow/pressure to the specific reference value with additional guidance that if the reference value cannot be achieved with reasonable effort, then the test will be considered valid if the steady state flow rate is within the proceduralized limits of +2% / -1 % of the reference value or discharge pressure is within the proceduralized limits of+ 1% / -2% of the reference value.

Using the provisions of this request as an alternative to the specific requirements ofISTB-5121, ISTB-5122, ISTB-5123, ISTB-5221, ISTB-5222, ISTB-5223, ISTB-5321, ISTB-5322, and ISTB-5323 as described above will provide adequate indication of pump performance and continue_ to provide an acceptable level of quality and safety. Based on the determination that the use of controlled reference value ranges provides an acceptable level of quality and safety, this proposed alternative should be granted pursuant to 10 CFR 50.55a(z)(l).

DURATION: 5th Interval beginning January 1, 2016 and ending December 31, 2025.

8.0 INSERVICE TESTING OF VALVES 8.1 GENERAL This IST Program was developed to comply with the testing provisions of 10 CFR 50.SSa(f) which delineates the testing requirements for ASME Class 1, 2, and 3 valves. The Code of record required by 10 CFR 50.SSa(b) (3) for 5th Interval Valve IST is the ASME OM Code-2004 Edition with Addenda through OMb-2006 (, hereafter referred to as the OM Code. The supplemental guidance of NRC NUREG-1482, Revision 2 have been applied to the extent practicable. In cases where specific Code requirements cannot be met, relief has been requested from these requirements.

Valves in the program are listed by MPL Number in tables for Units 1 and 2, respectively, and will be tested in accordance with the Code unless otherwise specified in this program.

8.2 SCOPE Safety related ASME Class 1, 2, and 3 valves with functions described in ISTA:-1100 are included within the scope of this program and are tested using the provisions of the ()M Code. Containment isolation valves located in non safety related systems are considered safety related for containment purposes and are, therefore, tested under the provisions of the OM Code and 10 CFR 50, Appendix

], as applicable. In cases where Code requirements are impractical or an alternate testing method is considered an improvement over OM Code requirements, a relief request has been developed.

Valve relief requests are located under a separate tab.

It is recognized that 10 CFR 50 Appendix A GDC-1, and Appendix B, Criterion XI intend that all valves necessary for safe operation of the plant be tested to demonstrate that they will perform satisfactorily in service. This testing is required to be performed at a level commensurate with the safety function of the valve, and is generally performed per the requirements of the plant Technical Specifications or other regulatory requirements.

RCIC System (lESl and 2E51)

No credit is taken in any of the accident analyses for the RCIC system (re: NRC SER dated 08/21/1997). Some RCIC System valves that do not perform a containment isolation function are still considered to be important and thus require a certain level of testing and have, therefore, been included in this program as Augmented Components. This testing will be performed in a manner similar to the OM Code testing and should adequately detect degradation. The testing of these valves is included in this program only to provide a readily accessible, documented method of testing. Subsequently, relief requests are not considered to be required.

valvetst.doc 8-1 Version 1.0

Diesel Generator Fuel Oil Transfer and Air Start Systems (1R43 and 2R43)

The Diesel Generator Fuel Oil Transfer and Air Start System valves are not ASME Class components and are not included in the scope as defined in Regulatory Guide 1.26 (September 1974). However, these valves are considered to be essential valves requiring a high level of testing and have, therefore, been included in this program as Augmented Components.. Testing of these valves will be performed in a manner similar to that found in the OM Code, which should adequately detect degradation in these particular valves. While similar to OM Code testing requirements, the testing of these valves is included in this program only to provide a readily accessible, documented method of testing. Subsequently, relief requests are not considered to be required.

Spent Fuel Pool Cooling (1G51 and 2G51)

The Spent Fuel Pool Cooling System valves have not been included in this Program because they are not considered to be safety related. Credit is taken in the FSAR for Plant Service Water as the safety grade makeup source for the spent fuel pool, and the RHR system is available as the backup cooling source. Although credit is taken in the FSAR for Plant Service Water as the safety grade makeup source for the spent fuel pool, the numerous manual valves that would be required to change position to facilitate this alignment will not be included in the 1ST program scope. This position is based on the fact that various makeup supply sources are available (e.g. demin, fire protection, etc.), the relatively long timeframe available to re-align ~he system and the amount of makeup that would be required is relatively small.

Jockey Pump System (1E21 and 2E21)

The Core Spray Jockey system is not within the 1ST scope (see Pump Basis for justification). Only the Jockey Pump to RHR and Core Spray isolation valves are included in the 1ST Program. Safety related instrumentation provides an alarm in the main control room if water inventory is depleted in the RHR and Core Spray System piping. Therefore, testing of other Jockey Pump System valves is not warranted because they do not have an active safety function as described in ISTA-1100.

Control Rod Drive System (lCll and 2Cll)

As described in Section 4.4.6 of NUREG-1482. Revision 2, certain individual CRD Valves should be tested to the extent practical. All subject valves except the scram discharge volume vent and drain valves will be tested using the technical specification frequency. Specific frequencies for each valve and the bases for the frequency are given in the valve basis.

The Unit 1 scram discharge volume vent and drain valves do not operate independently of one another. One switch operates all six valves and the valves are required to operate in a particular sequence to provide closure of all valves within a Technical Specification allowable time.

Therefore, quarterly individual stroke time testing of these valves is not practical. As an alternative test, these valves will be exercised quarterly but not timed. For Unit 1, the total valve sequence response time will be verified to be within Technical Specification requirements each refueling outage.See Relief Request RR-V-1 For Unit 2, the valves will be stroke timed each refueling outage.

and Refueling Outage Justification ROJ-V-29.

The scram insert and withdraw valves are solenoid valves that full stroke rapidly. Measuring the full stroke required by the OM Code is impractical for these valves; therefore, verification that the valvetst.doc 8-2 Version 1.0

associated control rod meets the required scram insertion time will be used as the alternate method to detect degradation of these valves. See Technical Position TP-09 for additional description. The scram discharge volume check valves are required to open to fulfill their safety function. Required flow is achieved through these valves during the technical specification control rod drive insertion tests.

The charging water HCU check valves are required to open and to close to fulfill their safety function. Forward flow operability is proven during Technical Specification testing and reverse flow closure will be proven by a leakage/pressure decay test.

The cooling water header HCU check valves and the drive water insert and withdraw valves are exercised to their safety related position (closed) during weekly CRD exercise testing.

Nitrogen Inerting System (1T48 and 2T48)

The only portions of the 1 (2) T 48 system (Nitrogen Inerting System) which are considered to be within the scope of inservice testing are those associated with primary containment and vacuum relief. The Hatch Unit 1 primary containment is inerted during normal operation to minimize the potential of hydrogen combustion for a LOCA, where hydrogen is produced due to the zirconium and steam reaction. However, this function is considered to be outside the scope of consideration for inservice testing.

An evaluation is included in the IST Bases Document for certain components which do not provide a containment isolation or vacuum relief function due to the nature of the particular component.

These evaluations are included for convenience and-information.

Architect Engineer review of the boundaries for ASME Section XI scope resulted in inclusion of components only associated with containment isolation. Therefore, since components associated with nitrogen purge, venting, and nitrogen makeup were not included in the ASME XI ISI boundaries, containment isolation and vacuum relief are considered to be the only safety related functions for IST.

8.3 LEAKAGE RATE TESTING 8.3.1 PRESSURE ISOLATION VALVES (PIV)

Pressure isolation valves (PIVs) are defined as two normally closed valves in series that isolate the Reactor Coolant System (RCS) from the attached low pressure system. Event V pressure isolation valves (Wash 1400) are defined in Section 4.4.4 of NUREG-1482, Revision 2 as "two check valves in series at a low pressure/RCS interface whose failure may result in a LOCA that bypasses containment." At Plant Hatch, there are no normal operating conditions in which two check valves function as the RCS/low pressure interface, therefore, Event V PIVs are not applicable.

Pressure isolation valves are not listed in the Technical Specifications; therefore, they were selected using the above definition. Each pressure isolation valve is designated "PIV" in the "Frequency" column in the valve tables. Some valves function as both pressure and containment isolation valves, and are designated as '.'PIV/CIV."

valvetst.doc 8-3 Version 1.0

Instrumentation to monitor the leakage downstream of each pressure isolation valve during power operation was not a design requirement of Plant Hatch. Also, while it is practical to test several of the valves individually, the ability to isolate and test each valve separately was not a design consideration. Subsequently, all valves cannot be practically tested on an individual basis. A leakage test will be performed at least every 24 months or each refueling outage (unless the valve has been classified as a good performer as defined in Relief Request RR-V-10 and the testing interval has been extended) as follows:

a. A valve that serves only as a pressure isolation valve is tested at operating differential pressure or at a reduced pressure as allowed by ISTC-3630(b)(4), using water as a test medium. The leakage observed during a reduced pressure test is then adjusted to a "function maximum pressure differential value" as required by ISTC-3630(b)(4). The allowable leakage at operating differential pressure for RCS/low pressure piping interface valves is 0.5 gpm (1892 cc/min) per inch of valve size up to a maximum of 5 gpm. The allowable leakage for the Feedwater interface valves, optionally included as PNs, is specified by SNC for each specific valv~.

b. An RCS/low pressure piping interface valve that also functions as a containment isolation valve (CIV) is Appendix J, Type C tested using CN acceptance criteria since these criteria are more stringent. Acceptable leakage for these valves is always less than the PN criterion of 1892 cc/min per inch of valve size, even when the adjustment to the "function maximum pressure differential value" is performed. A Feedwater/low pressure piping interface valve that also functions as a containment isolation valve (CN) is Appendix], Type C tested using CN acceptance criteria.

8.3.2 CONTAINMENT ISOLATION VALVES {CIV)

All containment isolation valves that receive a Type C, Appendix J test are included in this Program and are identified as "CN" in the "Frequency" column in the valve tables.

Any changes in the Appendix J, Type C testing scope will be reflected in this document with appropriate changes to the tables. CNs that do not require Type C leakage testing have not been included in the Program Tables as Category A valves. CNs that are Type A tested only are included in the applicable Integrated Leak Rate Test procedure and CNs that do not require any leakage testing (e.g., water sealed) are listed as Category B or C valves.

SNC conforms to the requirements of ISTC-3630 (e) to the extent practical by assigning a specific leakage limit to each valve or penetration assembly. Limits are based on the type and size of each valve, the number of valves within the test boundary, and historical leakage data. Administrative leakage limits for all Category A valves not referenced in the Technical Specifications or that reference a note in 42IT-TET-001-1/2 are determined by the guidance in 42EN-INS-002-0. See Technical Position 10 for further information.

As a rule, test configurations have the least number of boundary valves practical to perform the Type C test; however, the piping arrangement at Plant Hatch generally requires the pressurization of a combination of CNs and block valves simultaneously.

In these cases, a leakage limit is applied to each penetration test configuration. During the testing of the penetration, if the measured leakage exceeds the limit for the penetration, causes are investigated and repairs made to specific valves as necessary.

valvetst.doc 8-4 Version 1.0

The intent of OM Code to detect degradation (and repair if necessary) of each valve due to service related conditions is therefore met.

8.3.3 LEAK TIGHT VALVES (LTV)

The RCS Excess Flow Check Valves do not have specific allowable leakage rates. They are included in the IST Program and are reverse-leakage tested to confirm closure only.

They are tested in accordance with the Technical Specifications as defined in Relief Request RR-V-9.

8.3.4 LEAK TEST TYPE AND FREQUENCY DESIGNATION

All valves that require any type of Leakage Test are designated by "LT" in the "Test" Column in the Valve Test Tables.

"LTV: in the "Freq" Column indicates an EFCV which is tested at the frequency described in ROJ-V-2.

"CIV" in the "Freq" Column indicates a leakage test frequency in accordance with 10 CFR 50 Appendix J, Option B.

"PIV" in the "Freq" Column indicates a leakage test is required at least once every 24 months or each refueling outage (unless the valve qualifies as a "good performer" and the interval is extended per Relief Request RR-V-1 O).

"PIV/CIV" in the "Freq" Column indicates a leakage test is required at least once every 24 months or each refueling outage.

If the leakage test frequency is different than described above, the required frequency is listed in the "Freq" Column (e.g. some CIVs have a test frequency of every 24 months (2Y) or each Refueling Outage (RO) in order to confirm closure).

8.4 FAIL SAFE VALVES Unless otherwise specified in the program tables, additional fail safe testing will not be performed. Stroking the valve full cycle during normal testing causes loss of power to the actuator as required by ISTC-3560. Therefore, additional testing to provide the fail safe capability is not required. See Technical Position TP-04 for additional guidance.

8.5 PASSIVE POWER OPERATED VALVES A passive power operated valve does not perform a mechanical motion during the course of accomplishing a system safety function. These valves are identified as such in the "AP" Column in the Valve Tables. Per Table ISTC-3500-1, passive Category B valves do not require any exercise testing and verification that actual valve position is indicated by remote position indication lights ev~ry two years is the only testing required. Passive Category B power operated valves that are deenergized in their safety position under administrative controls during power operation will not have remote position indication verification.

See Technical Position TP-03 for additional guidance.

8.6 CHECK VALVES valvetst.doc 8-5 Version 1.0

It is SNC's position to extend the test frequency of any non safety direction tests to refueling outage without a Refueling Outage Justification (ROJ) or without a Cold Shutdown Justification (CSJ) .

3. The CRD cooling water check valves are exercised to their safety related position (closed) during monthly CRD exercise tests (notch in/notch out). Insertion of the CRD verifies that the required pressure boundary is intact and the check valve is closed. Open exercising is confirmed during normal operation. If the check valve did not open adequately, a HIGH Temperature ALARM would be received in the MCR for the respective CRD.

4. This containment isolation valve is not required to be leak rate tested que to the line it is on terminating below the water level of the torus. No leakage test is necessary to satisfy Appendix J requirements as the torus is postulated to remain water filled during post LOCA conditions. See the Appendix J Program for additional details.

5. Deleted

6. Closure of this pump discharge check valve is proven during pump surveillance testing. There are two pumps on each train; therefore, when one pump is being tested the other is not operating. For the pump being tested to pass the required hydraulic parameters, the discharge check valve on the non operating pump must close to prevent diverted flow. If the valve remained open, the pump test would be unsuccessful. This is consistent with the guidelines provided in Section 4.1.5.1 of NUREG-1482, Revision 2.

18. Valve closure is confirmed during quarterly HPCI pump surveillance testing by monitoring the barometric condenser level.

19. This valve will be disassembled and inspected on a frequency determined to provide adequate assurance that the valve is operable.

20. These RCIC valves will be tested in a comparable manner to the test required by ROJ-V-24 for comparable function HPCI valves.

21. These valves are air operated valves without indicating lights or control switches. Measurement of stroke times will be performed by observation of the stem movement when the RCIC room cooler is placed into service.

22. This check valve has a safety function in both the open and closed directions. Testing need only be performed on an interval when it is practicable to perform both the open and closed tests.

23. Each diesel fuel oil transfer pump is tested semi-annually using an ultrasonic flow instrument to monitor flow. The flow rate required for the valve to fulfill its safety related open function will be verified during this semi-annual pump test. The discharge piping from each Diesel Fuel Oil Transfer Pump is supplied with two check valves in series. There are two pumps located in each 40,000 gallon storage tank which discharge into a single line to the associated Day Tank. Satisfactory performance of a fuel oil transfer pump test also proves closure of at least one of the in series check valves on the associated idle transfer pump.

24. Stroke times cannot be measured for the~e valyes because there are no position indicators and visual observation is not possible due to the valve design. These valves will be tested as part of the Diesel Generator Air Start Test. Acceptable diesel generator start during monthly manual start tests will be used to verify valve operability. Stroke time will be verified to be acceptable semi-annually and each refueling outage by system timing during diesel generator auto start testing. This is consistent with the Code allowed exemption for skid mounted components. (re; ISTC-1200(c))

25. The air receiver inlet check valves are tested quarterly for reverse flow closure using a gross leakage test and each refueling outage using a pressure decay test.

26. This testable check valve is exercised quarterly to the open position using the test switch. Each refueling outage the valve is visually inspected and the force required to open the disk is measured to ensure operability and monitor degradation.

27. This is a passive containment isolation valve, Category A. This valve is never opened except for quarterly exercising of the associated torus to drywell vacuum breaker (1 (2)T 48-F323s). Therefore, quarterly exercising and stroke timing of these solenoid valves is not required.

CODE EDITION ASME OM Code-2004 Edition with Addenda through OMb-2006 AND ADDENDA:

REQUIREMENTS: Establish limiting values of valve stroke time and measure individual valve stroke time per ISTC-5131.

REASON FOR This relief request is a re-submittal of NRC approved 4th Interval relief request REQUEST: RR-V-1 that was based on the ASME OM Code-2001 Edition. This 5th Interval request for relief, RR-V-1, is based on the ASME OM Code-2004 Edition with Addenda through OMb-2006. There have been no substantive changes to the OM Code requirements or to the basis for use, which would alter the previous NRC Safety Evaluation c.onclusions. (See References for SER date and TAC numbers associated with RR-V-1).

A limiting value of stroke time cannot be specified for the air operated scram '

discharge volume vent and drain valves and they cannot be individually stroked and timed. In order to prevent water hammer induced damage to the system during a full CRD scram, plant Technical Specifications require that system valve operation is adjusted so that the outboard vent and drain valves (F035A&B, F037) fully close at least five seconds after each respective inboard vent and drain valve (FOlOA&B, FOll). All valves must be fully closed in less than forty-five (45) seconds.

Additionally, the system is adjusted so that the inboard vent and drain valves (FOlOA&B, FOll) start to open at least five seconds after each respective outboard vent and drain valve (F035A&B, F037) upon reset of a full core scram.

The valves are not equipped with individual valve control switches and cannot be individually stroke timed. Because of the adjustable nature of the valve control system, individual valve stroke timing would not provide any meaningful information for monitoring valve degradation. System design prevents stroke timing these valves during normal operation without disabling the Reactor Protection System Scram Signal to the valves. Disabling this signal requires the installation of electrical jumpers and the opening of links in energized control circuits which increase the potential for a Reactor Scram.

12- 2 Version 1.0

RR-V-1 (Cont.)

PROPOSED The valves will be exercised quarterly but not timed. Additionally, the total valve RELIEF AND sequence response time will be verified to be less than Technical Specifications BASIS: requirements during each refueling outage when a complete stroke time test is performed. The above proposed relief provides a reasonable assurance of operational readiness since the valves will be exercised quarterly and total valve response time will be tested each refueling outage. Based on the impracticality of performing testing in accordance with the Code requirements, and in consideration of the burden on SNC if the Code requirements were imposed, this proposed relief should be granted pursuant to 10 CFR 50.SSa(f) (6)(i).

CODE EDITION ASME OM Code-2004 Edition with Addenda through OMb-2006 AND ADDENDA:

REQUIREMENTS: ASME OM Code, 2004 Edition, Appendix I, paragraph 1-1360 requires Class 2 and 3 nonreclosing pressure relief devices (rupture discs) to be replaced every 5 years, unless historical data indicates a requirement for more frequent replacement.

REASON FOR This alternative is a re-submittal of NRC approved 4th Interval relief request RR-V-5 REQUEST: that was based on the ASME OM Code-2001 Edition. This 5th Interval request for relief, RR-V-5, is based on the ASME OM Code~2004 Edition with Addenda through OMb-2006. There have been no substantive changes to this alternative, to the OM Code requirements or to the basis for use, which would alter the previous NRC Safety Evaluation conclusions. (See References for SER date and TAC numbers associated with RR-V-5).

The subject rupture discs are supplied by Continental Disc Corporation. Southern Nuclear Operating Company requested the supplier to perform cyclic testing, to destruction, of a disc that had previously been installed in the HPCI system at Plant Hatch. The test disc was installed in an appropriate disc holder and flange assembly which simulated the installed configuration. The rupture disc assembly was cycled from full vacuum to 70% of the ambient burst pressure (219 psig). The cycle testing was conducted at ambient room temperature. Since a rupture disc is a differential pressure relief device, cycling conditions were achieved by placing a constant 15 psig pressure on the downstream side of the rupture disc and cycling the upstream pressure from zero to 70% of the ambient burst pressure plus 15 psig. The 15 psig added to the upstream cycling pressure compensates for the constant 15 psig pressure on the downstream side. An electronic counter recorded each cycle. The test disc completed 2,788 cycles before failure occurred. The rupture disc burst in the normal fashion as with disc of this design.

The HPCI system is typically tested every 3 months, but for conservatism a test frequency of each month will be assumed. Monthly testing would result in approximately 72 tests during 3 operating cycles (i.e., 72 months). To meet the Code 5-year replacement frequency, the disc must be replaced every 2nd refueling outage (48 months) or after approximately 48 HPCI system tests. Therefore, a change from replacement every 48 months to every 72 months is insignificant when compared to 12 - 6 Version 1.0

RR-V-5 (Cont.)

the expected life of the disc as proven by the number of cycles required for disc rupture by vendor testing.

Plant Hatch operates on a 24-month fuel cycle. Replacement every 6 years results in replacement every 3rd refueling outage whereas a 5-year replacement results in replacement every 2nd refueling outage. Extension of the replacement frequency by 1-year will coincide with the fuel cycle for Plant Hatch.

PROPOSED The subject rupture discs will be replaced at least once every 3rd refueling outage, ALTERNATIVE corresponding to once every 6 years.

AND BASIS:

As proven by the vendor testing, the subject rupture discs have adequate margin for operation well beyond the requested 6-year replacement frequency. Therefore, the proposed alternative provides an acceptable level of quality and safety and should be granted pursuant to 10CFR50.55a(z)(l).

DURATION: 5th Interval beginning January 1, 2016 and ending December 31, 2025.

RR-V-8 (Cont.)

REASON FOR Pursuant to 10 CFR 50.55a, "Codes and Standards," paragraph (z)(2), relief is REQUEST: requested from the frequency specifications of the ASME OM Code. The basis of the relief request is that the Code requirement presents an undue hardship without a compensating increase in the level of quality or safety.

ASME OM Code Section IST establishes the inservice test frequency for all components within the scope of the Code. The frequencies (e.g., quarterly) have always been interpreted as "nominal" frequencies (generally as defined in the Table 3.2 of NUREG 1482, Revision 2) and Owners routinely applied the surveillance extension time period (i.e., grace period) contained in the plant Technical Specifications (TS) Surveillance Requirements (SRs). The TS typically allow for a less than or equal to 25% extension of the surveillance test interval to accommodate plant conditions that may not be suitable for conducting the surveillance (SR 3.0.2). However, regulatory issues have been raised concerning the applicability of the TS "Grace Period" to ASME OM Code required inservice test frequencies irrespective of allowances provided under TS Administrative Controls (i.e., TS 5.5.6, "lnservice Testing Program," invokes SR 3.0.2 for various OM Code frequencies).

The lack of a tolerance band on the ASME OM Code inservice test frequency restricts operational flexibility. There may be a conflict where a surveillance test could be required but where it is not possible or not desired that it be performed until sometime after a certain restricted plant condition is cleared . Therefore, to avoid this conflict, the surveillance test should be performed as soon as it is practicable. The NRC recognized this potential issue in the TS by allowing a frequency tolerance as described in TS SR 3.0.2. The lack of a similar tolerance applied to OM Code testing places an unusual hardship on the plant to adequately schedule work tasks without operational flexibility.

Thus, just as with TS required surveillance testing, some tolerance is needed to allow extending OM Code testing intervals. Interval extension is to facilitate test scheduling and considers plant operating conditions that may not be suitable for performance of the required testing (e.g., performance of the test would cause an unacceptable increase in the plant risk profile due to transient conditions or other ongoing surveillance, test or maintenance activities). Such extensions are not intended to be used repeatedly merely as an operational convenience to extend test intervals beyond those specified.

PROPOSED ASME OM Code establishes component test frequencies that are based either ALTERNATIVE on elapsed time periods (e.g., quarterly, 2 years, etc.) or on the occurrence of AND BASIS: plant conditions or events (e.g., cold shutdown, refueling outage, upon detection of a sample failure, following maintenance, etc.).

12- 9a Version 1.0

RR-V-8 (Cont.)

a. Components whose test frequencies are based on elapsed time periods shall undergo lnservice Testing at frequencies as specified in the Hatch Technical Specifications (TS 5.S:6) and shown in the following table:

Specified Time Period Between Tests Frequency Weekly At least once per 7 days Monthly At least once per 31 days Quarterly At least once per 92 days Semiannually At least once per 184 days Yearly or Annually At least once per 366 days

b. The specified time period between tests may be extended as follows:

i. For periods specified as less than 2 years, the period may be extended by up to 25% for any given test.

ii. For periods specified as greater than or equal to 2 years, 'the period may be extended by up to 6 months for any given test.

c. Components whose test frequencies are based on the occurrence of plant conditions or events (e.g., cold shutdown, refueling outage, upon detection of a sample failure, following maintenance, etc.) may not have their period between tests extended except as allowed by the ASME OM Code.

d. Period extensions may not be applied to the test frequency requirements specified in Subsection ISTD, Preservice and Inservice Examination and Testing of Dynamic Restraints (Snubbers) in Light-water Reactor Nuclear Power Plants, as Subsection ISTD contains its own rules for period extensions.

e. Period extensions of 25% may also be applied to accelerated test frequencies (e.g., pumps in Alert Range) and other less than two year test frequencies not specified in the table above.

This relief is requested citing the guidance found in ASME approved Code Case OMN-20. Based on the determination that compliance with the Code requirement results in a hardship without a compensating increase in the level of quality and safety, this proposed alternative should be granted pursuant to 10 CFR50.55a(z) (2).

REASON FOR Pursuant to 10 CFR 50.55a, "Codes and Standards", paragraph (z)(l), relief is REQUEST: requested from the requirements of ASME OM Code ISTC-3522(a), ISTC-3522{c),

and ISTC-3700 for the subject valves. The basis of the Relief Request is that the proposed alternative would provide an acceptable level of quality and safety.

PROPOSED Excess flow check valves will be tested on a representative sample basis at the ALTERNATIVE frequency specified in Technical Specifications Surveillance Requirement 3.6.1.3.8.

AND BASIS:

Functional testing with verification that flow is checked will be performed per Technical Specification 3.6.1.3.8 during refueling outages. Surveillance Requirement 3.6.1.3.8 allows a "representative sample" of EFCVs to be tested every refueling outage, such that each EFCV will be individually tested approximately every ten years. The sample groups are representative of the various plant configurations, models, sizes, and operating environments.

The EFCVs have position indication in the control room. Check valve remote position indication is excluded from Regulatory Guide 1.97 as a required parameter for evaluating containment isolation. The remote position indication will be verified accurate at the same frequency as the functional test prescribed in Technical Specification Surveillance Requirement 3.6.1.3.8. Although inadvertent actuation of an EFCV during operation is highly unlikely due to the spring poppet design, Plant Hatch monitors the EFCVs indications on a daily basis as part of the Operations routine. Corrective Action documents are initiated for any EFCVs with abnormal position indication displays and repairs are scheduled for the next refueling outage.

Excess flow check valves are provided in each instrument process line that is part of the reactor coolant pressure boundary. The excess flow check valve is designed so that it will not close accidentally during normal operation, will close if a rupture of the instrument line occurs downstream of the valve, and can be reopened, when appropriate, after a closure.

As detailed in Unit 1 FSAR Section 5.2.2.5.4 and Unit 2 FSAR Section 6.2.5.3.3, Plant Hatch has incorporated into the design of each instrument source line a 0.25-inch restricting orifice as close to the RPV as possible. This is a redundant design feature which, along with the EFCV, will limit leakage to a level where the integrity and functional performance of the secondary containment and its associated air treatment systems {e.g., filters and the standby gas treatment system) are maintained.

The coolant loss is well within the capabilities of the reactor coolant makeup system, and the potential offsite exposure is substantially below the guidelines of IOCFRIOO.

Additionally, the design and installation of the excess flow check valves at Plant Hatch follow the guidance of Regulatory Guide 1.11 12- 10c Version 1.0

RR-V-9 (Cont.)

PROPOSED Testing the subject valves quarterly or during cold shutdown is not practicable, based ALTERNATIVE on plant conditions. These valves have been successfully tested throughout the life AND BASIS (Cont.): of Plant Hatch and they have shown no degradation or other signs of aging.

The technology for testing these valves is simple and has been demonstrated effectively during the operating history of Plant Hatch. The basis for this alternative is that testing a sample of EFCVs each refueling outage provides a level of safety and quality equivalent to that of the Code-required testing.

Excess flow check valves are required to be tested in accordance with ISTC-3522, which requires exercising check valves nominally every three months to the positions required to perform their safety functions. ISTC-3522(c) permits deferral of this requirement to every reactor refueling outage. Excess flow check valves are also required to be tested in accordance with ISTC-3700, which requires remote position indication verification at least once every 2 years.

10CFR50 Appendix J testing is only applicable to EFCVs if they perform a containment isolation function. EFCVs are not required to close in response to a containment isolation signal and are not required to operate under post-LOCA conditions. As discussed in Reference 2, the functioning of EFCVs is not necessary to remain within 10CFRlOO limits. Consequently, for purpose of 10CFR50, Appendix J, CIV testing, EFCVs do not provide a containment isolation function and are exempt from consideration under Appendix J.

The testing described above requires removal of the associated instrument or instruments from service. Since these instruments are in use during plant operation, removal of any of these instruments from service may cause a spurious signal, which could result in a plant trip or an unnecessary challenge to safety systems.

Additionally, process liquid will be contaminated to some degree, requiring special measures to collect flow from the vented instrument side and also will contribute to an increase in personnel radiation exposure.

Testing on a cold shutdown frequency is impractical considering the large number of valves to be tested and the locations in which the test fixtures must be located.

Considering the number of valves to be tested and the conditions required for testing, it is also a hardship to test all of these valves during refueling outages.

Improvements in refueling outage schedules have minimized the time that is planned for refueling and testing activities during the outages.

The excess flow check valve is a simple and reliable device. The major components are a poppet and spring. The spring holds the poppet open under static conditions.

The valve will close upon sufficient differential pressure across the poppet.

Functional testing of the valve is accomplished by venting the instrument side of the valve. The resultant increase in flow imposes a differential pressure across the poppet, which compresses the spring and decreases flow through the valve.

Industry experience as documented in GE Nuclear Energy topical report NED0-32977-A, "Excess Flow Check Valve Testing Relaxation," indicates the EFCVs have 12 - 10d Version 1.0

RR-V-9 (Cont.)

PROPOSED a very low failure rate. The report indicates similarly that many reported test ALTERNATIVE failures at other plants were related to test methodologies and not actual EFCV AND BASIS (Cont.): failures. In addition, the SER for that report assumed a 5 fold increase in failure rate to account for any potential aging influence and the resultant failure potential over 10 years was still found to not be significant. Test history at Plant Hatch shows a very low failure rate and no evidence of common mode failure, which is consistent with the findings of the NEDO report. The EFCVs at Plant Hatch, consistent with the industry, have exhibited a high degree of reliability, availability, and provide an acceptable level of quality and safety.

The Plant Hatch Technical Specifications detail what frequency is required to maintain a high degree of reliability and availability and as an alternative will provide an acceptable level of quality and safety. Therefore, Southern Nuclear Co.

requests relief pursuant to 10CFR50.55a (z) (1) to test excess flow check valves on a representative sample basis and at the frequency specified in Plant Hatch Technical Specifications Surveillance Requirements (SR) 3.6.1.3.8.

CODE EDITION ASME OM Code-2004 Edition with Addenda through OMb-2006 AND ADDENDA:

REQUIREMENTS: ISTC-3630(a) - "Leakage Rate for other than Containment Isolation Valves" -

Frequency. Tests shall be conducted at least once every 2 years.

Pursuant to 10 CFR 50.SSa, "Codes and Standards", paragraph (a)(3), relief is REASON FOR requested from the requirement of ASME OM Code ISTC-3630 (a). The basis of the REQUEST: relief request is that the proposed alternative would provide an acceptable level of quality and safety.

ISTC-3630(a) requires that leakage rate testing for pressure isolation valves be performed at least once every 2 years. Pressure Isolation Valves (PIVs) are not specifically included in the scope for performance-based testing as provided for in 10CFRSO Appendix J Option B. The concept behind the Option B alternative for containment isolation valves is that licensees should be allowed to adopt cost effective methods for complying with regulatory requirements. Additionally, NEI 94-01 describes the risk-informed basis for the extended test intervals under Option B. That justification shows that for valves which have demonstrated good performance by passing their leak rate tests for two consecutive cycles, further failures appear to be governed by the random fai.lure rate of the component. NEI 94-01 also presents the results of a comprehensive risk analysis, including the statement that "the risk impact associated with increasing [leakrate] test intervals is negligible (less than 0.1 % of total risk)." The valves identified in this relief request are all in water applications, CIV valves are tested in accordance with Appendix J Requirements using air. PIV testing is typically performed at lower pressures, such as for Appendix J Requirements, are acceptable provided the results are extrapolated to system functional differential pressure. Plant Hatch applies the extrapolated values to both PIV and CIV values. This relief request is intended to provide for a performance-based scheduling of PIV tests at Hatch. The reason for requesting this relief is dose reduction / ALARA. Recent historical data was used to identify that PIV testing alone each refuel outage incurs a total dose of approximately 400 milliRem. Assuming all of the PIVs remain classified as good performers the extended test intervals would provide for a savings of 800 mR over a 6 year period per unit.

NUREG 0933 Issue 105 (Interfacing Systems LOCA at LWRs) discussed the need for PIV leak rate testing based primarily on 3 pre-1980 historical failures of applicable valves industry-wide. These failures all involved human errors in either operations or maintenance. None of these failures involved inservice equipment degradation. The performance of PN leak rate testing provides assurance of acceptable seat leakage with the valve in a closed condition. Typical PIV testing does not identify functional problems which may inhibit the valves ability to re-position from open to close. For check valves, such functional testing is accomplished per ASME OM Code ISTC-3522. Power-operated valves are routinely full stroke tested per ASME OM Code to ensure their functional capabilities. At Hatch, these functional tests for PIVs are performed only at a Cold Shutdown or Refuel Outage frequency.

12 - lla Version 1.0

RR-V-10 (Cont.)

Such testing is not performed online in order to prevent any possibility of an inadvertent ISLOCA condition. The 24 month functional testing of the PIVs is adequate to identify any abnormal condition that might affect closure capability.

Performance of the separate 24 month PIV leak rate testing does not contribute any additional assurance of functional capability - it only determines the seat tightness of the closed valves.

PROPOSED Hatch proposes to perform PIV testing at intervals ranging from every refuel to every ALTERNATIVE third refuel. The specific interval for each valve would be a function of its AND BASIS: performance and would be established in a manner consistent with the Containment Isolation valve (CIV) process under 10CFR50 Appendix J Option B. 12 of the 36 valves listed are also classified as CIVs and are currently leak rate tested with air according to 10CFR50 Appendix J methodology every 2 years to satisfy their PIV leakage test requirement (with acceptance criteria correlated to water at function maximum pressure differential). Whether the valve is a CIV/PIV or PIV only, the valve must have two consecutive leakage tests which meet its acceptance criteria to be considered a good performer. That is, the test interval may be extended to every third refuel outage upon completion of two consecutive periodic PIV tests with results within prescribed acceptance criteria. The test interval will be extended to a specific value in a range of frequencies from 30 months up to a maximum of 75 months (as described in NEI 94-01 Revision 3-A). The test interval shall not exceed 75 months with a 3 month grace period (i.e., a total of 78 months). Any test failure will require a return to the initial (every RFO) interval until good performance can again be established.

The primary basis for this relief request is the historically good performance of the

PIVs and desire to reduce personnel dose (ALARA). With the testing being performed every refueling outage has resulted in approximately 180 tests with 2 failures which yields a failure rate of approximately 1 percent.

Additional basis for this relief request is provided below:

Separate functional testing of power-operated PIVs and Condition Monitoring of Check Valve PIVs per ASME OM Code.

Low likelihood of valve mispositioning during power operations (procedures, interlocks).

Air test vs. water test - degrading seat conditions tend to be identified sooner with air testing.

Relief valves in the low pressure (LP) piping - these relief valves may not provide Inner-System Loss of Coolant Accident (ISLOCA) mitigation for inadvertent PIV mispositioning but their relief capacity can accommodate conservative PIV seat leakage rates.

Alarms that identify high pressure (HP) to LP leakage - Operators are highly trained to recognize symptoms of a present ISLOCA and to take appropriate actions.

Isolation of these lines results in primary system pressure spikes, reactor power fluctuations, and increased flow in the unisolated steam lines. This unstable operation can lead to a reactor scram, as discussed in NUREG-0626.

Pressure transients resulting from full stroke testing MSIVs increase the chances of actuating primaiy system safety/relief valves. Also, stroking these valves during power operation requires decreasing the unit to 75%

power, therefore, resulting in a substantial capacity factor loss prior to, during, and after the test.

PARTIAL QUARTERLY STROKE TESTING: These valves are partially stroked each quarter to satisfy the requirements of Improved Technical Specification SR 3.3.1.1.9 on an alternate test basis.

COLD SHUTDOWN TESTING: Full stroke exercise and stroke time each cold shutdown, unless the valve has been tested within the past 3 months.

Inadvertent opening of these valves is prevented by system interlocks that require the primary system pressure to be below the CS operating pressure prior to opening or the associated upstream isolation valve to be closed. Routinely stroking these valves open and closed during power operation would place the plant in an unsafe condition by potentially exposing low pressure piping to reactor coolant pressure, which could result in an interfacing system LOCA (ISLOCA). Reliance on the interlocks with the upstream valves to prevent an ISLOCA would not be a safety-conscious strategy.

An ISLOCA can produce consequences that are very difficult to mitigate. The best prevention is to minimize the probability of occurrence. An important contribution to such minimization is to test pressure boundary valves only at conditions of low reactor coolant system pressure.

QUARTERLY PARTIAL STROKE TESTING: None. The valve operating circuitry does not allow for partial stroke capability.

COLD SHUTDOWN TESTING: These valves will be full stroke exercised and stroke timed each cold shutdown, unless the valve has been tested within the past 3 months.

If the valve is exercised closed during normal operation and fails to re-open, the entire system safety function would be rendered inoperable. If the testing were to result in a loss of subsequent closure capability these valves would be unable to perform their safety function to close for containment isolation. The primary containment is inerted dw:ing normal operation and a plant shutdown would be required to repair the valve and restore the system safety function.

VALVE(S): 1G31-F001, 1G31-F004 2G31-F001, 2G31-F004 CATEGORY: A CLASS: 1 FUNCTION: RWCU Pump Suction CIV QUARTERLY TEST REQUIREMENT: Exercise and stroke time quarterly per ISTC-3510 COLD SHUTDOWN TEST JUSTIFICATION: The RWCU System is in service during normal plant operation to maintain reactor coolant chemistry within Technical Specifications limits. These isolation valves must be open to allow for RWCU system operation. Exercising and stroke timing these valves closed quarterly requires the RWCU system to be taken out of service which could result in degraded chemical makeup of the reactor coolant and subjects the entire RWCU system to unnecessary transients. These unnecessary transients could lead to degradation and failure of other related system components (e.g., pumps, valves, demineralizers) and the potential loss of the system availability which would ultimately cause a plant shutdown. Shutting down and re-starting of the RWCU system in order to exercise and stroke time these valves also results in undesired exposure to personnel involved in the actual surveillance activity.

Additionally, returning the system to service with reactor at normal operating conditions poses the potential for a system auto isolation which results in additional work of having to backwash the demineralizers before returning them to service.

QUARTERLY PARTIAL STROKE TESTING: None. The system logic does not allow partial closure of these valves.

COLD SHUTDOWN TESTING: These valves will be full stroke exercised and stroke timed each cold shutdown, unless the valve has been tested within the past 3 months.

VALVE(S): 1P41-F049, 1P41-F050 2P64-F045,2P64-F047 CATEGORY: A CLASS: 2 FUNCTION: Drywell Air Cooler CIV QUARTERLY TEST REQUIREMENT: Exercise and stroke time quarterly per ISTC-3510 COLD SHUTDOWN TEST JUSTIFICATION: Closure of any one of these valves would interrupt cooling water flow to the drywell coolers (Unit 1) or the drywell cooler condensers (Unit 2). This interruption of cooling water flow could result in an increase in the drywell temperatures which ultimately could require shutting the plant down due to Technical Specification requirements.

QUARTERLY PARTIAL STROKE TE~TING: None. The valve circuitry does not allow partial closure of these valves.

COLD SHUTDOWN JUSTIFICATION CSJ-V-9 SYSTEM: Plant Service Water (PSW)

VALVE(S): 1P41-F310A thru D 2P4I-F316A thru D CATEGORY: B CLASS: 3

._J FUNCTION: Turbine Building PSW Supply Shutoff QUARTERLY TEST REQUIREMENT: Exercise and stroke time quarterly per ISTC-3510 COLD SHUTDOWN TEST JUSTIFICATION: The individual service water supply trains combine into a common header prior to entry into the turbine building. During normal operation at least three service water pumps are required to provide cooling water to the safety and non-safety related loads.

Closure of one of these normally open valves in any sequence during normal operation would significantly decrease cooling water flow to the turbine building equipment, including the operating turbine and turbine related loads. A decrease in cooling water flow of this magnitude could cause a rapid increase in temperatures for these components and potentially extensive damage. Quarterly stroke testing would require power reduction or forced shutdown.

There may be specific times in support of corrective maintenance that it will be necessary to perform testing on these valves on-line, but routinely causing perturbations to the plant is adequate justification for deferral.

If one of these valves was to fail in its safety related position (Closed) during exercising, increased temperatures and a resultant plant shutdown would most certainly occur.

QUARTERLY PARTIAL STROKE TESTING: None. The valve circuitry does not allow partial closure of these valves.

COLD SHUTDOWN TESTING: These valves will be full stroke exercised and stroke timed each cold shutdown, unless the valve has been tested within the past 3 months.

Both Reactor Recirc pumps must operate continuously while the plant is at full power. Reducing plant power and securing the Recirc pumps one at a time for the purpose of this valve testing would create significant nuclear safety concerns and lost generation.

QUARTERLY PARTIAL STROKE TESTING: None, valve operating circuitry does not provide for partial exercising.

COLD SHUTDOWN TESTING: These valves will be full stroke exercised and stroke timed each cold shutdown, unless the valve has been tested within the past 3 months.

COLD SHUTDOWN JUSTIFICATION CSJ-V-11 SYSTEM: Nuclear Boiler (Feedwater)

VALVE(S): 2B21-F076A&B CATEGORY: C CLASS: 2 FUNCTION: Feedwater Isolation QUARTERLY TEST REQUIREMENT: Check valves shall be exercised nominally every 3 months per ISTC-3510 COLD SHUTDOWN TEST JUSTIFICATION: Feedwater injection is required during normal operation.

Isolating one of the feedwater lines to perform a closure test would require reducing reactor power by approximately 50%

and would introduce main feedwater flow transients into the reactor due to a non-symmetrical injection pattern and the potential for a reactor protection system actuation. Closure testing consists of using the installed air actuator to close the valve and verify proper light indications. This can only be done with no feedwater flow and with HPCI and RWCU secured (to prevent backpressure on the valve).

QUARTERLY PARTIAL STROKE TESTING: No means exists to partially stroke these valves while at power.

The actuator cannot overcome the opening force created by feed flow through the valve.

COLD SHUTDOWN TESTING: Thes,e normally-open feedwater check valves have an air assist operator to ensure tight closure and are provided with remote position indicating lights. Closure will be confirmed each cold shutdown, but not more frequently than once per 3 months, by actuating the closure mechanism and observing the indicating lights.

COLD SHUTDOWN JUSTIFICATION CSJ-V-12 SYSTEM: Drywell Pneumatic System VALVE(S): 1/2P70-F004, FOOS, F066, F067 CATEGORY: B CLASS: 2 FUNCTION: DW Pneumatic CIVs QUARTERLY TEST REQUIREMENT: Exercise and stroke time quarterly per ISTC-3510 COLD SHUTDOWN TEST JUSTIFICATION: These valves are open to provide N 2 to accumulators for safety related, pneumatically operated valves located inside the primary containment, primarily some of the safety relief valves {SRVs) and inboard main steam isolation valves (MSIVs). Pneumatic pressure is required for the Automatic Depressurization function of selected SRVs and the MSIVs rely on pneumatic pressure to hold-them open as well as assist in closing. These valves are normally open and fail open on loss of power to ensure that the N 2 supply is maintained.

These valves auto close on an indication of system pressure less than dtywell pressure or high flow into the drywell pneumatics headers {line break). If any of these valves is closed during normal operation, and then failed to reopen, it could result in a loss of accumulator pressure and resultant loss of partial ADS and closure of one or more MSIVs.

Therefore, quarterly exercising is not justified and valves will be exercised during each Cold Shutdown.

QUARTERLY PARTIAL STROKE TESTING: Not Applicable COLD SHUTDOWN TESTING: . These valves will be full stroke exercised and stroke timed each cold shutdown, unless the valve has been tested within the past 3 months.

VALVE(S): 1B21-F010A&B 2B2l-F010A&B CATEGORY: AC CLASS: 1 FUNCTION: Feedwater Line Injection and CIV TEST Exercise quarterly or at cold shutdown per ISTC-3510 and ISTC-REQUIREMENT: 3522 DEFERRAL Feedwater injection is required during normal operation. Isolating JUSTIFICATION: one of the feedwater lines to perform a closure test would require reducing reactor power by approximately 50% and could potentially introduce reactor flux imbalance due to a non-symmetrical feedwater injection pattern.

The closure testing is not practical during non-refueling Cold Shutdowns due to the Complexity and loc_ation of the testing setup (reference NUREG-1482 Rev. 2 Section 4.1.6). The closure testing consists of a leakrate type test and also requires entry into the drywell, which would have to be de-inerted.

Normal feedwater flow is significantly greater than the flowrate required for the open safety function (HPCI or RCIC injection).

Therefore, the valve is proven capable of opening to the required position with normal feedwater injection during power operation.

ALTERNATE These check valves will be exercised and confirmed to close during TESTING: scheduled Appendix J Program leak rate testing. The bi-directional exercise requirement in the open position is satisfied oy feedwater flow during normal power operation.

BASIS FOR JUSTIFICATION: Feedwater injection is required during normal operation.

Isolating one of the feedwater lines to perform a closure test would require reducing reactor power by approximately 50%

and could potentially introduce reactor flux imbalance due to a non-symmetrical feedwater injection pattern.

The closure testing is not practical during non-refueling Cold Shutdowns due to the complexity and location of the testing setup (reference NUREG-1482 Rev. 2 Section 4 .1.6).

The drywell is inerted during normal operation. Closure testing is not practical during non-refueling Cold Shutdowns due to the complexity of the testing setup (reference NUREG-1482 Rev. 2 Section 4.1.6), which could potentially delay the startup of the unit.

Quarterly testing could damage the seals.

Closure testing is not practical during non-refueling Cold Shutdowns due to the complexity of the testing setup (reference NUREG-1482 Rev. 2 Section 4.1.6), which could potentially delay the startup of the unit.

ALTERNATE TESTING: These check valves will be exercised and confirmed to close during scheduled Appendix J Program leak rate testing.

Flow through each check valve is experienced only during the scram of the associated CRD*unit.

Per NUREG 1482, Rev. 2, Section 4.4.6, verifying that the associated control rod meets the scram insertion time limits defined in the plant's Technical Specifications can be an acceptable alternative method of detecting degradation of these valves.

ALTERNATE TESTING: The required flow is achieved through the valves during the Technical Specification Control Rod Scram Insertion tests.

(1) As a minimum, 10% of the CRDs are scram timed on a rotating basis every 200 cumulative days of operation in mode 1.

This test cannot be performed during normal operation because stopping the pumps results in loss of cooling water to all CRD mechanisms and seal damage could result. Additionally, it is impractical to perform this testing during cold shutdown because the CRD pumps supply seal water to the Reactor Recirc and Reactor Water Clean-up pumps. At least one Recirc pump and RWCU pump is normally maintained in operation during non-refueling cold shutdowns to maintain reactor coolant chemistry in accordance with Technical Specification requirements. This justification and alternative testing is also described in NUREG 1482 Revision 2 Section 4.4.6.

ALTERNATE TESTING: Reverse flow closure will be confirmed at each refueling outage by performance of a HCU accumulator pressure decay test. Open verification is demonstrated by the water inventory in the accumulators being maintained by flow through this valve during normal operation.

ISTC-3521 BASIS FOR JUSTIFICATION: The Hydraulic Control Units (HCU) are integrally designed systems for controlling rod drive movements. Individual valve testing is not possible without causing a control rod scram with a resulting change in core reactivity. Quarterly testing of these valves increases the potential to violate plant Technical Specifications which govern the methods and frequency of reactivity changes. In addition, these are power operated valves that full-stroke in milliseconds. Therefore, measuring their full-stroke time is impractical. Verifying that the associated control rod meets the scram insertion time limits defined in the Technical Specifications provides an alternate method of detecting valve degradation. Trending the stroke times of these valves is impractical and unnecessary since they are indirectly stroke timed and no meaningful correlation between the scram time and valve stroke time can be obtained.

This justification and alternative testing is also described in NUREG 1482 Revision 2 Section 4.4.6.

ALTERNATE TESTING: Technical Specification Control Rod Scram Insertion Time testing serves to verify proper operation of each of these valves.

(1) As a minimum, 10% of the CRDs are scram timed on a rotating basis every 200 cumulative days of operation in mode 1.

(2) After each refueling outage or reactor shutdown ~ 120 days all control rods are scram tested from the fully withdrawn position.

VALVE(S): 1C41-F006, 1C41-F007 2C41-F006, 2C41-F007 CATEGORY:AC CLASS: 1 FUNCTION: SBLC Iajection Line Isolation TEST REQUIREMENT: Verify forward flow operability and closure quarterly or at cold shutdown per ISTC-3510 and ISTC-3522 BASIS FOR JUSTIFICATION: Forward flow exercising can only be performed by injecting into the reactor vessel using the SBLC pumps. The pumps are normal! y aligned to a sodium pentaborate storage tank and they would have to be aligned to demineralized water for exercise testing of the check valves. The associated piping would have to be flushed prior to the test and refilled with sodium pentaborate after the open exercise test. Closure testing can only be performed by a leakrate type test. Testing of these normally closed valves quarterly or during cold shutdown would require:

(1) Actuation and replacement / restoration of the explosive squib valves, 1(2)C41-F004A(B), to allow injection into the RPV (open exercise)

(2) Personnel entry into the primary containment to operate the manual test boundary valve 1(2)C41-F008 (close exercise) and, (3) Loss of operability of the SBLC system (close exercise).

Due to the time required for testing setup, the complexity of the test, and the time required for associated valve alignments, attempting to perform this testing at cold shutdown could potentially delay startup of the unit.

ALTERNATE TESTING: These valves are full flow exercised once each refueling outage during SBLC Initiation (Technical Specifications surveillance) testing. These check valves will be exercised and confirmed to close during scheduled Appendix J Program leak rate testing.

These normally open check valves are located inside the primary containment and therefore are inaccessible during power operation. The primary containment is inerted during normal operation and personnel entry is prohibited. Therefore, testing during normal operation is impracticable.

The closure testing is not practical during non-refueling Cold Shutdowns due to the complexity and location of the testing setup (reference NUREG-1482 Rev. 2 Section 4.1.6).

ALTERNATE TESTING: These check valves will be exercised and confirmed to close during scheduled Appendix J Program leak rate testing. The bi-directional exercise requirement is satisfied during power operation by verification of satisfactory Nitrogen purge flow during Transversing Incore Probe (TIP) operations.

VALVE(S): 1E21-F006A&B 2E21-F006A&B CATEGORY:AC CLASS: 1 FUNCTION: Core Spray Injection and PN TEST REQUIREMENT: Verify forward flow operability quarterly or at cold shutdown per ISTC-3510 and ISTC-3522.

BASIS FOR RELIEF: System configuration does not provide for full or partial flow exercise testing during normal operation. Core spray injection during normal operation is impossible because reactor pressure is significantly greater than core spray injection pressure.

Electrical power is removed from the equalization* valve (1 (2)E21-F037 A(B)) during normal operation which disables the partial exercise test circuit. These valves are located inside the primary containment, are PIVs, and potential erroneous signal indications caused by restoring power to the test circuit and partial exercising could not be readily distinguished from actual valve problems without shutting down the plant, de-inerting the containment, and performing a containment entry.

Therefore, partial exercising during normal operation is impracticable.

Since these valves are located inside the primary containment and are inaccessible during normal operation or at cold shutdown unless the containment is de-inerted, mechanical exercising quarterly or during cold shutdown is also impracticable. The containment is not de-inerted during an unplanned shutdown _unless containment entry is absolutely necessary.

The only feasible ways to confirm full stroke operational readiness is bX 1) full flow exercising by injecting condensate storage tank lCST) water into the RPV during a refueling outage, 2) mechanical exercising in accordance with ISTC-5221 (b), or 3) disassembly, inspection, and full stroke

exercising in accordance with ISTC-522l(c).

ALTERNATE TESTING: Each check valve is full flow exercised open each refueling outage by injecting into the RPV. Core Spray is utilized to flood the reactor cavity in preparation for fuel movement each refueling outage and both core spray pumps* inject at the accident required flow rate.

These check valves will be exercised and confirmed to close during scheduled Appendix J Program leak rate testing.

Use of the above test methods provides sufficient confirmation of valve operational readiness and provides adequate information to monitor for valve degradation.

VALVE(S): 1E21-F044A&B 2E21-F044A&B CATEGORY:C CLASS: 2 FUNCTION: Containment Isolation Barrier TEST REQUIREMENT: Reverse flow closure quarterly or at cold shutdown per ISTC-3510 and ISTC-3522 .

BASIS FOR JUSTIFICATION: These valves are located in the jockey pump recirculation line back to the suppression pool. The water seal provided by the Suppression Pool means that these valves function as containment boundary valves and not Category A leak rate tested valves. The only viable means of proving closure is by performing a reverse leakage pressure test. Performing such a pressure test guarterly would require removing the associated jockey pump ls) from service and would likely result in not maintaining the associated train of RHR and Core Spray piping full of water as required by Technical Specifications.

This would result in unnecessary ECCS unavailability and potential entries into Technical Specification 3.0.3.

This type of testing requires a significant amount of time for test setup, valve alignment and actual performance of the test.

Testing at cold shutdown could potentially delay startup of the unit which is further discussed in NUREG-1482, Rev. 2, Section 4.1.6. Also, the RHR and Core Spray Systems are normally required to be operable during brief periods of cold shutdown. This testing can be more safely and efficiently performed during refueling outages These valves provide only a containment boundary function and are not exposed to severe operating conditions which would promote rapid degradation; closure exercise testing at a refueling outage frequency will provide sufficient assurance of continued component operability.

ALTERNATE TESTING: Valves will be reverse flow closure tested each refueling outage by performance of a reverse leakage pressure test similar to an Appendix J, type C test.

These valves are interlocked to prevent valve opening when reactor coolant pressure is > 145 psig.

Defeating the interlock and stroke testing these valves during normal operation could result in over-pressurization and potentially catastrophic damage to the low design pressure RHR pump suction piping.

These valves are also in the flowpath for Shutdown Cooling. During refueling conditions the reactor head is removed and the vessel is flooded up. This greatly increases time to boil because of the large additional water volume as compared to a Cold Shutdown non-refueling situation. There are also more redundant decay heat removal options available during the refueling conditions than in cold shutdown condition. Testing of these valves involves interruption and/or reconfiguration of Shutdown Cooling. With reduced time to boil during typical Cold SID conditions any interruptions of Shutdown Cooling incur additional risk. This risk overshadows any benefit derived from slightly more frequent testing of these valves.

ALTERNATE TESTING: Exercise and stroke time each refueling outage.

Closed exercising of these check valves cannot be confirmed quarterly during surveillance testing because there is no available indication that each valve is actually closed.

Individually exercising these in series check valves during normal operation would require the HPCI turbine exhaust vacuum relief line to be isolated thus rendering the HPCI system inoperable per Technical Specification definition.

ALTERNATE During the local leakrate test for valves 1 (2)E41-F104 and 1 (2)E41-Fll 1 TESTING: the piping is pressurized between valves 1 (2) E41-Fl 11 and 1(2)E41-Fl04. Valve 1(2)E41-F103 is then vented as part of the test to exercise both check valves open thus ensuring their vacuum breaker function since this flow rate will be greater than that required for vacuum relief.

Closure verification of at least one of the in series valves is proven during quarterly HPCI pump surveillance testing. If at least one of the valves did not close, steam would bypass the suppression pool into the torus bay air space and cause a resultant temperature increase.

Reverse flow closure is also proven in conjunction with LLRT of valves 1(2)E41-Fl04 and 1(2)E41-Flll. With the boundary between valves 1 (2)E41-Fl04 and 1 (2)E41-Fll 1 pressurized, separate vents for the 1 (2)E41-Fl02 and 1 (2)E41-F103 are individually opened in a sequence that confirms each valve to be closed.

A type C LLRT or a similar pressure decay type test will be performed at the interval established by the Appendix J pro~am to confirm individual open and close exercising of valves 1(2)E41-F102 and 1 (2)E41-Fl03.

REFUELING OUTAGE JUSTIFICATION ROJ-V-25 SYSTEM: Reactor Water Cleanup (1G31)

VALVE(S): 1G31-F039 and 1G31-F203 CATEGORY: AC CLASS: 1 FUNCTION: RWCU Return Line CIV TEST REQUIREMENT: Verify reverse flow closure quarterly or at cold shutdown per ISTC-3510 and ISTC-3522 BASIS FOR JUSTIFICATION: These normally open check valves are located in the RWCU return line to the reactor vessel thru each feedwater line. To establish the necessary test boundary for each of these valves will require closure of the manual feedwater valve, 1B21-F011AlB), which is located inside primary containment.

Entry into primary containment is not possible during normal operation due to high radiation and the nitrogen inerted atmosphere.

Closure testing is also not practical during non-refueling Cold Shutdowns due to the location and complexity of the testing setup (reference NUREG-1482 Rev. 2 Section 4.1.6), which could potentially delay the startup of the unit.

ALTERNATE TESTING: These check valves will be exercised and confirmed to close during scheduled Appendix J Program leak rate testing. The non-safety function open direction is proven during power operations by normal RWCU flowrates.

VALVE(S): 1Ell-F3090 2Ell-F3090 CATEGORY: AC CLASS: 1 FUNCTION: Thermal overpressure protection and CIV.

TEST REQUIREMENT: Verify forward and reverse flow operability quarterly or at cold shutdown per ISTC-3510 and ISTC-3522.

BASIS FOR JUSTIFICATION: These valves are located inside the primary containment and are therefore inaccessible during normal operation or at cold shutdown unless the containment is de-inerted. The containment is never de-inerted during an unplanned shutdown unless containment entry is absolutely necessary. Exercising these valves partially open for their thermal overpressure protection function or in the reverse direction as a CIV requires entry into containment and the use of temporary test equipment to perform a leak test in addition to passing air flow through the valves to demonstrate their partial opening capability. Due to the considerable effort associated with these test activities, exercise testing to the partially open or closed positions quarterly or during cold shutdown is considered impractical due to the necessity of utilizing temporary test equipment inside containment. This deferral of test frequency is acceptable per the discussion provided in NUREG-1482, Rev. 2, Section 4.1.6.

ALTERNATE TESTING: These check valves will be exercised and confirmed to close during scheduled Appendix J Program leak rate testing. Since there is no accident flow rate associated with the valves' safety function in the open direction, demonstrating partial opening capability will be performed in conjunction with scheduled seat leakage testing of Ell-FOOS and Ell-F009.

Use of the above test methods provides sufficient confirmation of valve operational readiness and provides adequate information to monitor for valve degradation.

REFUELING OUTAGE JUSTIFICATION ROJ-V-28 SYSTEM: RHR VALVE(S): 1Ell-F021A&B 2Ell-F021A&B CATEGORY: B CLASS: 2 FUNCTION: Containment Spray Injection and Isolation TEST REQUIREMENT: Exercise and stroke time active Category B valves quarterly or cold shutdown per ISTC-3510 and ISTC-3521 BASIS FOR JUSTIFICATION: These valves are located in the RHR Containment Spray lines. The RHR system was designed as a closed system outside containment, therefore, only one isolation valve is required for each containment penetration. The 1/2Ell-F016A(B) valve provides the inboard containment isolation boundary (PCIV) while the 1/2El 1-F021A(B) function as barrier valves allowing for Appendix J leakrate testing of the associated closed system penetration and PCIV.

The RHR containment spray piping is maintained filled with water up to the 1/2Ell-F016A(B) when the system is required to be operable to preclude the possibility of water hammer upon system initiation.

However, the piping between the inboard barrier valve (1/2El 1-F021A/B) and the PCIV could possibly contain water, due to seat leakage after extended periods of normal plant operation. Any accumulated water must be confirmed drained prior to opening the inboard barrier valve (1/2E21-F021A/B) for exercising and stroke timing. Draining this piping is required to prevent water from entering the primary containment (drywell) and potentially damaging safety related equipment.

Exercising and stroke timing 1/2Ell-F021A(B) requires personnel to attach a temporary hose to a drain connection between valves 1/2E l 1-F021A/B and 1/2Ell-F016A/B (respectfully) and drain the piping prior to exercising the 1/2El 1-F021A(B). After 3-months of normal operation, typically 2 - 5 gallons of water are drained, but the volume may vary depending on the seating characteristics of the 1/2E l 1-F016A (B) valve.

Connecting the temporary hose and draining the piping requires personnel entry into elevated areas of the Reactor Building for Unit 1 and into the RWCU Hx. Room for Unit 2. The RWCU Hx. Room is a "HIGH Radiation" area during normal operation and thus requires special Health Physics consideration and coverage. For both Units, personnel must consider safety issues related to accessing elevated components, ALARA, and proper disposal of contaminated water. In addition, a Technical Specification Required Action Statement (RAS)

REFUELING OUTAGE JUSTIFICATION ROJ-V-28 (Cont) must be entered when the manual drain valve is opened due to primary containment integrity and isolation implications.

These considerations make it unreasonable to perform exercise and stroke time testing on a quarterly or cold shutdown frequency. These valves are included in the plant's motor operated valve program (reference: NRC Generic Letters 89-10 and 96-05) which provides added assurance that the valves are properly maintained and tested to ensure they will function in accordance with the design requirements and perform their required safety function. Exercising and stroke timing quarterly or during unplanned cold shutdowns for IST does not provide any significant additional benefit or assurance for valve operational readiness.

PARTIAL EXERCISING: None practical as described above.

ALTERNATE TESTING: Valves will be exercised and stroke timed each refueling outage.

This actuation method bypasses the time delay relays, and all six valves are actuated at the same time. Stroke timing the valves during these quarterly TS strokes is impractical due to.

the logistics requirements (i.e., six operators and six stop watches). The quarterly stroking of these valves is done specifically to satisfy the TS requirement and is not credited as an IST exercise test.

ALTERNATE TESTING: During each refueling outage, an exercise test will be performed which simulates a SCRAM signal from RPS and the time delay relays are then part of the test circuit. All six valves (6 people with 6 stop watches) will also be stroke timed in both directions and the specific time delay values will be verified during this test.

SYSTEM: RHR VALVE(S): 1Ell-F050A&B 2Ell-F050A&B CATEGORY: AC CLASS: 1 FUNCTION: LPCI and Pressure Isolation TEST REQUIREMENT: Verify forward flow operability quarterly or at cold shutdown per ISTC-3510 and ISTC-3522.

BASIS FOR JUSTIFICATION: The plant and system configuration does not provide for full flow exercising during normal operation. LPCI injection during normal operation is* impossible because reactor pressure is significantly greater than LPCI injection pressure. Therefore full exercising with flow on a quarterly frequency is impracticable.

Achieving design flow through these valves during Cold Shutdowns is also impractical. It is normal plant practice to utilize only one loop of RHR in Shutdown Cooling mode for any short term unscheduled shutdown due to the efforts involved in system alignment, flushing, pipe warm-up and swapping of loops. At least one of the valves is exposed to partial flow when the RHR System is operating in the SDC Mode of operation. However, achieving design flow during a Cold Shutdown could have negative impact on the control of Reactor cooldown rates and also requires additional man-power to align two RHR pumps for injection. Requiring both loops of RHR shutdown cooling to be placed in operation during an unplanned shutdown for the sole purpose of full stroke exercising each check valve is impractical and imposes increased activities on operation's personnel involved with other shutdown activities and could extend shutdown duration.

These valves are located inside the primary containment and are therefore inaccessible during normal operation or at cold shutdown unless the containment is de-inerted. The containment is never de-inerted during an unplanned shutdown unless containment entry is absolutely necessary. Therefore mechanical exercising quarterly or at cold shutdown is impractical.

The only way to full flow exercise these valves is to align both RHR pump suctions in a loop to the shutdown cooling suction line or mechanically exercising in accordance with ISTC-522l(b) using a torque wrench each refueling outage.

ROJ-V-30.doc 14-32 Version 1.0

REFUELING OUTAGE JUSTIFICATION ROJ-V-30 (cont.)

ALTERNATE TESTING: Both loops of RHR will be aligned with both pumps taking suction from the shutdown cooling line and design accident flow will be injected to the RPV confirming full flow exercise of the associated check valve each refueling outage or each valve will be mechanically exercised during its respective refueling outage. As an alternative, mechanical exercising with a torque wrench may be performed every refueling outage. Either test will provide an acceptable method of open exercise functionality per ISTC-3510 and ISTC-3522.

Entry into the drywell is not permitted during normal operation due to the drywell being inerted during normal operation. The steamchase is inaccessible during normal operation due to extreme temperatures and dose rates.

Because of the setup time, valve alignments and complexity of the test, attempting to perform these tests during cold shutdowns would potentially delay the startup of the unit and is further discussed in NUREG-1482 Rev. 2 Section 4.1.6.

ALTERNATE TESTING: These check valves will be exercised and confirmed to close during scheduled Appendix J Program leak rate testing. The bi-directional exercise requirement to the open position is satisfied during Code required exercise testing of the MSIVs each cold shutdown.

If the associated pump is tripped, it also creates a potential for exceeding the permissible temperature differential between the recirculation loops for pump re-start. In addition, the valves are located inside the primary containment and are inaccessible during normal operation, which precludes an operator from manually re-opening the valve in case of actuator failure. Each valve's operating circuitry does not allow partial closure during normal operation. Also, requiring that the reactor recirculation pump be stopped and restarted during each cold shutdown solely to allow for the testing of these valves is not warranted because repetitive cycling would increase pump wear and stress, as well as the number of cycles of related plant equipment, and could extend the length of cold shutdowns.

This deferral is described in NUREG 1482, Rev. 2, Section 3.1.1.4.

BASIS FOR JUSTIFICATION: These valves provide the boundary between high pressure (460 psig) and low pressure (125 psig) piping during normal operation. Therefore, they are included in the IST Program.

The valves do not perform a safety related function in the open position. Therefore, they only require exercise open testing to meet bi-directional IST requirements.

The plant and system configuration does not provide for forward flow exercising during normal operation. To forward flow exercise these valves during normal plant operation would require draining water from the Core Spray system to forcibly initiate flow from the CST through these valves. Removing water from the Core Spray system would require a train of Core Spray to be declared inoperable for the sole purpose of this non-safety direction check valve testing.

Open functionality is verified during normal operation and shutdowns as evidenced by overcoming total system leakage and maintaining normal header pressures in the idle Core Spray System. Closure functionality is also verified by ensuring upstream relief valves 1E21-F024A&B do not lift when the respective Core Spray train is pressurized during quarterly system testing.

ALTERNATE TESTING: As a supplement to the above online functional verifications, 1E21-F030A&B will be grouped, disassembled, inspected, and/or mechanically exercised to prove open and closed functionality.

VALVE(S): 2B21-F077 A&B CATEGORY: AC CLASS: 1 FUNCTION: Feedwater Containment Isolation TEST REQUIREMENT: Check valves shall be exercised nominally every 3 months per ISTC-3510 BASIS FOR JUSTIFICATION: Feedwater injection is required during normal operation. Isolating one of the feedwater lines to perform a closure test would require reducing reactor power by approximately 50% and could potentially introduce reactor flux imbalance due to a non-symmetrical feedwater injection pattern.

Closure testing is not feasible during a cold shutdown, because these valves are located in the flowpath of the Reactor Water Cleanup (RWCU) System. Taking RWCU out of service during Cold Shutdowns for this closure testing could have adverse effects on RCS chemistry which could result in a plant startup delays.

I (Open Exercise) Normal feedwater flow is significantly greater than the flowrate required for the open safety function (HPCI or RCIC injection).

Therefore, the valve is proven capable of opening to the required position with normal feedwater injection during power operation.

ALTERNATE These check valves will be exercised and confirmed to close during TESTING: scheduled Appendix J Program leak rate testing. Open functionality is proven during normal operation by satisfactory feedwater injection flow.

Technical Position TP-01 (Page 1 of 3)

Bi-directional Testing of Check Valves with Non-Safety Positions Purpose The purpose of this Technical Position is to establish the station position for the verification of the non-safety direction exercise testing of check valves by normal plant operations.

Applicability This Technical Position is applicable to those valves which are included in the Inservice Testing Program that are required to be exercised tested in their non-safety related direction of flow. This position applies to those check valves required to be tested in accordance with Subsection ISTC (ASME OM Code 2004 Edition through 2006 Addenda) and Appendix II. This Technical Position does not apply to testing of the safety function (direction) of check valves'included in the Inservice Testing Program.

Background

The ASME OM Code 2004 through 2006 Addenda section ISTC-3550, "Valves in Regular Use",

states:

"Valves that operate in the course of plant operation at a frequency that would satisfy the exercising requirements of this Subsection need not be additionally exercised, provided that the observations otherwise required for testing are made and analyzed during such operation and recorded in the plant record at intervals no greater than specified in ISTC-3510."

Section ISTC-3510 requires that check valves shall be exercised nominally every 3 months with exceptions for extended periods referenced.

Section ISTC-5221 (a) (2) states:

"Check valves that have a safety function in only the open direction shall be exercised by initiating flow and observing that the obturator has traveled to either the full open position or to the position required to perform its intended function(s) (see ISTC-1100), and verify closure."

Section ISTC-5221 (a) (3) states:

"Check valves that have a safety function in only the close direction shall be exercised by initiating flow and observing that the obturator has traveled [to] at least the partially Version 1.0 E. I. Hatch 1ST Program Page 15- 2

Technical Position TP-01 (Page 2 of 3) open position, 1 and verify that on cessation or reversal of flow, the obturator has traveled to the seat. "

1 "The partially open position should correspond to the normal or expected system flow."

Normal and/or expected system flow may vary with plant configuration and alignment. Plant Hatch Plant Operations staff is trained in recognizing normal plant and system conditions, For check valves that have a non-safety function in the open position, Operator judgment has been deemed acceptable in determining whether or not the normal or expected flow rates for plant operation has been obtained. For check valves that have a non-safety related function in the closed position, Operator judgment is also deemed acceptable in determining whether or not flow has stopped or a differential pressure has established relative to a normal or expected flow rate, in order to verify appropriate obturator travel.

Position Where feasible, an additional test will be established which provides direct quantifiable measurement of the check valve operation in the non-safety direction. Testing need only be performed on an interval when it is practicable to perform both the open and close tests. Where plant design or system configuration does not support such a dedicated test, the following alternate verifications may be performed as follows:

1. An appropriate means shall be determined which establishes the method for determining the open/closed non-safety function of the check valve during normal operations. The position determination may be by direct indicator, or by other positive means such as changes in system pressure, flow rate, level, temperature, seat leakage, etc. This determination shall be documented in the respective Condition Monitoring Plan for the specific check valve group. For check valves included in the Inservice Testing Program and not included in the Condition Monitoring Plan, this determination shall be documented in the 1ST Bases Document for the specific check valve.

2. Observation and analysis of plant processes that a check valve is satisfying its non-safety direction function may used. For an example, consider a check valve that has a safety function only in the closed direction but is normally open to provide a flow path to maintain plant operations. If this check valve does not open to pass sufficient flow when required, an alarm or indication would identify a problem to the operator. The operator would respond by taking the appropriate actions. A CA document would then be generated for the abnormal plant condition which would identify the check valve failure.

3. Observation and analysis of plant logs and other records may be an acceptable method for verifying a check valves non-safety direction function verification during normal plant operations.

Version 1.0 E. I. Hatch IST Program Page 15- 3

Technical Position TP-01 (Page 3 of 3)

The open/closed non-safety function shall be recorded at a frequency required by ISTC-3510, nominally every 3 months, (with exceptions as allowed), in plant records such as Plant Hatch Nuclear Operating Logs, Electronic Rounds, chart recorders, automated data loggers, etc. The safety function direction testing requires a Quality Record in the form of a surveillance test.

Records as indicated above in 1 through 3 are satisfactory for the non-safety direction testing. A CA document shall be generated for any issues regarding check valve operability.

,Justification This Technical Position establishes the acceptability of the methods used in determining the ability of a valve to satisfy its non-safety function. Through normal plant system operation and Operator actions, a valves non-safety function is verified through either observation or analysis of plant records and logs. Additionally, the recording of parameters which demonstrate valve position is satisfied at a frequency in accordance with ISTC-3510. These actions collectively demonstrate the non-safety position of Inservice Testing Program check valves in regular use as required by ISTC-3550.

Passive Valves without Test Requirements Purpose The purpose of this Technical Position is to establish the Plant Hatch IST Program position for valves which perform a passive safety function.

Applicability This Technical Position is applicable to valves that perform a passive function in accordance with the definition in ISTA-2000 and do not have inservice testing requirements per Table ISTC-3500-1. Such valves maintain their obturator position and do not need to change obturator position to accomplish a specific function as described in ISTA-1100.

'An example is a manual valve which must remain in its normal position during an accident, to perform its intended function.'

For such passive valves which also have remote position indication, if the valves are administratively controlled by Plant Hatch procedures and locked in their safety position and/or have their power removed, they are also exempt from testing per ISTC-3700.

Position The Plant Hatch Inservice Testing Program, Valve Tables will not list valves that meet all of the following criteria.

The valve is categorized B (seat leakage in the closed position is inconsequential for fulfillment of the valves' required function(s)) in accordance with ISTC-1300.

The valve is considered passive (valve maintains obturator position and is not required to change obturator position to accomplish the required fimction(s)) in accordance with ISTA-2000.

The valve does not have a remote position indicating system which detects and indicates valve position OR

The valve has remote position indication but is administratively controlled by Plant Hatch procedures and locked in their safety position and/or have their power removed.

Passive Valves without Test Requirements

,Justification Valves that meet this position will not be listed in the Plant Hatch Inservice Testing Program, Valve Tables; however, the basis for categorization and consideration of active/passive functions shall be documented in the IST Program Basis Document.

Southern Nuclear Co./Hatch considers that if a passive valve equipped with remote position indication is under administrative control at all times during plant operation and if Operations does not have to take any actions based on light indication, the valves will not be subject to Position Indication Testing per ISTC-3700.

Technical Position TP-04 (Page 1 of 1)

Fail Safe Testing of Valves Purpose The purpose of this Technical Position is to establish the Plant Hatch IST Program position for fail safe testing of valves in conjunction with stroke time exercising or position indication testing.

Applicability This Technical Position is applicable to valves with fail-safe actuators required to be tested in accordance with ISTC-3560.

Background

The ASME OM Code 2004 through 2006 Addenda section ISTC-3560 requires; "Valves with fail-safe actuators shall be tested by observing the operation of the actuator upon loss of valve actuating power in accordance with the exercising frequency of ISTC-3510."

Position In cases where the valve operator moves the valve to the open or closed position following de-energizing the operator electrically, by venting air, or both, the resultant valve exercise will satisfy the fail safe test requirements and an additional test specific for fail safe testing will not be performed.

Plant Hatch will also use remote position indication as applicable to verify proper fail-safe operation, provided that the indication system for the valve is periodically verified in accordance with ISTC-3700.

Justification Fail Safe Testing tests the ability of the fail safe mechanism of the valves to go to its fail safe condition. Whether or not the actuation of this fail safe mechanism is due to Operator Action or failure of the valves air / electric power source, the resultant action of the valve will be the same.

Therefore, credit for the verification of a valves fail safe ability can be based on performance of either a stroke time exercising or full stroke position indication test for applicable valves.

Classification of Skid Mounted Components Purpose The purpose of this technical position is to clarify requirements for classification of various skid mounted components, and to clarify the testing requirements of these components.

Background

The ASME Code allows classification of some components as skid mounted when their satisfactory operation is demonstrated by the satisfactory performance of the associated major components. Testing of the major component is sufficient to satisfy lnservice Testing requirements for skid mounted components. In section 3.4 of NUREG 1482 Rev 2, the NRC supports the designation of components as skid mounted:

"The staff has determined that the testing of the major component is an acceptable means for verifying the operational readiness of the skid-mounted and component subassemblies if the licensee documents this approach in the IST Program. This is acceptable for both Code class components and non-Code class components tested and tracked by the IST Program."

In the 1996a addenda to the ASME OM Code (endorsed by 10CFR50.55(a) in October 2000), the term skid-mounted was clarified by the addition of ISTA paragraph 1. 7:

ISTA 1. 7 Definitions Skid mounted components and component sub assemblies - components integral to or that support operation of major components, even though these components may not be located directly on the skid. In general, these components are supplied by the manufacturer of the major component. Examples include: diesel skid-mounted fuel oil pumps and valves, steam admission and trip throttle valves for high-pressure coolant injection or Auxiliary Feedwater turbine-driven pumps, and solenoid-operated valve provided to control the air-operated valve.

Version 1.0 E. I. Hatch IST Program Page 15- 9

Technical Position TP-05 (Page 2 of 3)

Classification of Skid Mounted Components This definition was further clarified in the 1998 and 2001 Editions of the ASME Code:

ISTA-2000 DEFINITIONS Skid mounted pumps and valves - pumps and valves integral to or that support operation of major components, even though these components may not be located directly on the skid. In general, these pumps and valves are supplied by the manufacturer of the major component. Examples include: .

(a) diesel fuel oil pumps and valves; (b) steam admission and trip throttle valves for high-pressure coolant injection pumps; (c) steam admission and trip throttle valves for Auxiliary Feedwater turbine driven pumps; (d) solenoid-operated valves provided to control an. air-operated valve.

Additionally the Subsections pertaining to pumps (ISTB) and valves (ISTC) includes exclusions/exemptions for skid mounted components; ISTB-1200(c) Exclusions Skid-mounted pumps that are tested as part of the major component and are justified by the Owner to be adequately tested.

ISTC-1200 Exemptions Skid-mounted valves are excluded from this Subsection provided they are tested as part of the major component and are justified by the Owner to be adequately tested.

Position The 2004 ASME OM Code definition of skid mounted will be used for classification of components in the Plant Hatch Inservice Tes ting Program. In addition, for a component to be considered skid mounted:

The major component associated with the skid mounted component must be surveillance tested at a frequency sufficient to meet ASME Code test frequency for the skid mounted component.

Satisfactory operation of the skid mounted component must be demonstrated by satisfactory operation of the major component.

Version 1.0 E. I. Hatch IST Program Page 15- 10

Technical Position TP-05 (Page 3 of 3)

Classification of Skid Mounted Components

The 1ST Bases Document should describe the bases for classifying a component as skid mounted, and the 1ST Program Plan should reference this technical position for the component.

Recognition and classification of components as skid mounted eliminates the need for the redundant testing of the sub component(s) as the testing of major (parent) component satisfactorily demonstrates operation of the "skid mounted" component(s).

The components designated as skid-mounted are identified as such in the 1ST Bases. These include auxiliary pumps for the Emergency Diesel Generators and the HPCI system. Also several valves mounted on the EDG skids which are part of the lube oil, fuel oil and cooling water sub-systems.

Manual Valve Exercise Frequency Purpose The purpose of this Technical Position is to establish the Plant Hatch 1ST Program position for the frequency of exercising those manual valves which are required to be exercised.

Applicability This Technical Position is applicable to the manual valves included in the Inservice Testing Program.

Background

The ASME OM Code 2004 through 2006 Addenda section ISTC-3540 states; "Manual valves shall be full-stroke exercised at least once every 5 years, except where adverse conditions 1 may require the valve to be tested more frequently to ensure operationa_l readiness."

1 Harsh service environment, lubricant hardening, corrosive or sediment laden process fluid, or degraded valve components are some examples of adverse conditions.

However, 10CFR50.55a(p) (3) (vi) states: " Exercise interval for manual valves. Manual valves must be exercised on a 2-year interval rather that the 5-year interval specified in paragraph ISTC-3540 of the 1999 Addenda through the latest edition and addenda incorporated by reference in paragraph (b) (3) of this section, provided that adverse conditions do not require more frequent testing."

Position Plant Hatch will perform exercising of mapual valves within the scope of the IST Program at a frequency not to exceed 2 years.

Justification The NRC stipulates a frequency of exercising manual valves at least once every 2 years. This interval is more frequent than required by ASME OM Code 2004 through 2006 Addenda section ISTC-3540; therefore no other justification is required.

NOTE: At the present time there are no manual valves within the scope of the Plant Hatch 1ST Program.

Outside Design Basis Purpose The purpose of this Technical Position is to establish the Plant Hatch IST Program position for scoping decisions on components which may be functionally credited within the Appendix R program but are not .eonsidered in the scope of the IST Program.

Applicability This Technical Position is applicable to components outside the scope of UFSAR Chapter 15 accident mitigation or which have no specific functional requirement to achieve or maintain cold shutdown.

Background

The ASME OM Code 2004 through 2006 Addenda section ISTA-1100, "Scope", states that Inservice Testing requirements pertain to:

"Pumps and Valves that are required to perform a specific function in shutting down a reactor to the safe shutdown condition, in maintaining the safe shutdown condition, or in mitigating the consequences of an accident."

The Appendix R Program examines accident scenarios triggered predominantly by fires in various plant locations. An Appendix R scenario may verify the ability of operators to travel to a specific plant location and to manually manipulate a valve in a BOP system which would be operated as part of an orderly plant shutdown. The ASME IST scoping process looks at safety-related equipment - for example, the need to provide adequate makeup water to the reactor must be fulfilled by ECCS systems with an underlying assumption that all non-ASME systems are unavailable. Hatch would provide for testing of those ECCS systems to ensure they can meet their design basis capabilities. This is only one example of the differences between ASME IST pump and valve scoping and Appendix R scoping.

Those components are not credited with an active safety function as defined by the ASME IST scoping definitions, and will not be tested under the auspices of the Plant Hatch IST Program.

Position Consistent with industry practice, components required solely to mitigate the consequences of 10CFRSO Appendix R fires and station blackout events are outside the scope of the IST Program since these events are beyond the facility design basis.

Beyond design basis events are initiated by multiple (and sometimes complete) failures of safety-related components and systems. The facility design is based on requirement that each safety Version 1.0 E. I. Hatch 1ST Program Page 15- 13

Technical Position TP-07 (Page 2 of 2)

Outside Design Basis system be capable of performing its safety-related functions given a failure of the most limiting active component. Although regulations have been imposed that require the capability to cope with, or to mitigate these events, they are outside the scope of the facility accident analyses.

II II Components whose sole safety functions are to mitigate these outside design basis events are not required by regulations to be classified as safety-related, nor would they meet the ASME OM Code scoping definitions.

Justification Components credited in Appendix R or other outside design basis evaluations may or may not be safety-related. Testing of these components may be accomplished through the plant PM Program or other test scheduling processes. The expertise of the ISI/IST qualified personnel may be utilized to develop and even perform such testing. The 1ST Program involves a significant administrative burden and the scope of components within the program needs to be limited and in line with standard industry norms.

CRD Scram Valve Exercise Frequency Purpose The purpose of this Technical Position is to establish the station position for exercising the Control Rod Drive scram outlet valves.

Applicability This Technical Position is applicable to CRD valves that if exercised could potentially scram the reactor. This position is applicable to the following valves, which are typical of each individual hydraulic control unit:

Component Description Code Category Class lCll-HCU-114 CRD Scram Discharge Header Check Valve 2 C lCll-HCU-126 CRD Hydraulic System Inlet Scram Valve 1 B lCl 1-HCU-127 CRD Hydraulic System Outlet Scram Valve 1 B 2Cll-HCU-114 CRD Scram Discharge Header Check Valve 2 C 2Cll-HCU-126 CRD Hydraulic System Inlet Scram Valve 1 B 2Cll-HCU-127 CRD Hydraulic System Outlet Scram Valve 1 B Position Plant Hatch will exercise the subject valves at a frequency in accordance with Technical Specifications.

Justification The proper operation of each of these valves is demonstrated during scram time testing. During scram time testing, each drive's scram insertion time is measured and a fail-safe actuator test is performed. Plant Batch's Technical Specifications provide a specific time for individual CRD scram insertion. If a particular CRD 's scram insertion time is less than the specified time, the above valves are functioning properly.

Plant Hatch Technical Specification section 3.1.4.1 requires "Verify each control rod scram time is within the limits of Table 3.1.4-1 with reactor steam dome pressure~ 800 psig". At a frequency "Prior to exceeding 40% RTP after each reactor shutdown> 120 days" OR "Prior to exceeding 40% RTP after fuel movement within the reactor pressure vessel"

Plant Hatch Technical Specification section 3.1.4.2 requires "Verify, for a representative sample, each tested control rod scram time is within the limits of Table 3.1.4-1 with reactor Version 1.0 E. I. Hatch IST Program Page 15- 18

This justification is consistent with the NRC guidance provided in NUREG-1482 Revision 2, Section 4.4.6.

Valve Leakage Criteria Purpose The purpose of this Technical Position is to establish the Hatch IST Program position for determination of seat leakage and gross reverse leakage criteria on select valves.

Applicability This Technical Position is applicable to the following valves:

1. Category A valves which do NOT have a Technical Specification or UFSAR prescribed leakage limit.

2. Category C Check valves with close exercise testing that involves identification of reverse leakage

Position Per RER SNC505599 (Inservice Testing Acceptance Criteria Review with Respect to Design Analysis), for Category A valves described above the owner will establish administrative leakage limits. Administrative Leakage Limits for all Category A valves not referenced in the Technical Specifications will be determined by the guidance in 42EN-INS-002-0.

Also, Administrative Leakage Limits for those Category A valves which reference 42EN-INS-002-0 may be greater than the guidance included in 42EN-INS-002-0 due to past history where valves just minimally exceeded the guidance of 42EN-INS-002-0. Appendix J allows Licensees to establish Administrative Leakage Limits as long as total leakage is maintained less than total plant allowed leakage (La).

The closure exercise verification testing of some check valves involves a measurement of reverse leakage through the valve. Although criteria may be used for such leakage this does not imply that the valve would be a category A valve. Such criteria will be determined by the plant with the intent to show that the valve has in fact closed in reverse flow conditions. That criterion is not related to an analysis or commitment involving a maximum leakage path limit, and is not a contributor to La.

Service Water Pumps Inlet Pressure Accuracy Purpose The purpose of this Technical Position is to document the basis for the Inlet (suction) pressure measurement and accuracy used in Service Water Pump testing.

Applicability This Technical Position is applicable to the Unit 1 and 2 RHR Service Water and Plant Service Water pumps, and the unit 2 Standby Diesel Service water pump.

Position These vertical line shaft service water pumps take suction off the Intake basin connected to the Altarnaha River. The inlet pressure is a function of the elevation of the water in the intake basin, where the water level is maintained well above the actual suction bell of the pump. The pump has to create lift pressure to overcome the column of water. Because of this, pump differential pressure is calculated by adding the inlet pressure to the discharge pressure.

Inlet pressure is a calculated value, derived from the level of the water in the Intake basin. The formula for converting intake level to inlet pressure is: Pi= (114.5 feet - intake level) x 0.433 Instrument 1P41-N575 is used to measure intake level for the testing of both the Unit 1 and 2 pumps. Calibration procedure 57CP-CAL-013-1 shows that the 1P41N575 instrument is calibrated at +/- 1% for a range of 60 - 80 ft. For an instrument range of 20 ft, the maximum instrument inaccuracy is therefore 20*(0.1) = 0.2 ft.

At an intake level depth of 80 ft (maximum reading) the Pi would be 14.938 psi. Considering the maximum instrument inaccuracy of 0.2 ft the offset could be 80.2 ft; yielding a Pi value of 14.8519 psi. This is a maximum delta of 0.087 psi for the Pi measurement. The U2 Standby Diesel Service Water pump represents the most conservative condition, with a reference DP of only 105.9 for the CPT. The 0.087 psi possible offset in Pi would represent only a 0.082% impact on the measured DP. This is well within the 0.5% CPT pressure accuracy requirement in the ASME OM Code.

Requirements for use of Linear Regression and Data Normalization related to Pump Curves Purpose The purpose of this Technical Position is to establish the IST Program position on developing a linear regression for portions of pump curves and for normalizing pressure data within a specific flow band.

Applicability This Technical Position is applicable as a trending technique for all IST program pumps.

Position USE OF LINEAR REGRESSION There are situations where a portion of a pump curve needs to be quantified with a pressure to flow relationship such that a derivation of one parameter can be made given a single value of the other parameter. Most pump curves have a non-linear pressure (head) to flow relationship over the entire curve; however, for specific portions of the curve the pressure to flow relationship may be proportional enough to use linear regression as the derivation technique. The following are guidelines and requirements to be used in establishing a linear regression for a pump curve:

GUIDELINE 1: It is recommended that at least 6 points be measured for actual flow and pressure within the bounds of the linear regression region.

REQUIREMENT 1: It is required that at least 4 points be measured for actual flow and pressure within the bounds of the linear regression region.

GUIDELINE 2: It is recommended that the correlation coefficient (R) for the linear relationship be greater than O. 960 [abs]. This provides high confidence and accuracy for deriving values using the regression equation.

REQUIREMENT 2: It is required that the correlation coefficient (R) for the linear relationship be greater than 0.920 [abs]. This provides sufficient confidence and accuracy for deriving values using the regression equation.

\.,

GUIDELINE 3: It is recommended that the valid range of "x", typically flow, be no lower than the lowest measured flow data point and no higher than the highest measured flow data point.

REQUIREMENT 3: It is required that the valid range of "x", typically flow, be no lower than 90% of the lowest measured flow data point and no higher than 110% of the highest measured flow data point.

Technical Position TP-12 (Page 2 of 2)

DATA NORMALIZATION For pump testing where a reference band is allowed, there will be some scatter associated with the measured variable data: This guidance will allow the evaluator* a method to normalize that

. variable data in order to properly assess trends. The example used will be for a centrifugal pump where flow is set to an established reference value but allowance is given within the procedure for

. test flow to be plus or minus a given range about the reference value. Discharge and suction pressures are then measured at some measured flow value within the allowed test flow range.

. I The evaluator shall need to establish a known linear pressure-flow relationship, either from baseline data or from an assessment of a large quantity of pressure to flow data accumulated over several years. Using MS Excel, this linear relationship will need to be expressed as a table with at least 4 rows of data relating pressure to flow. One set of values should be at or below the minimum end of the allowable test flow band, another set at or above the maximum end and the remaining data at or very close to the middle (reference flow). The evaluator shall then use the Excel Forecast function to input an actual measured test flow and derive what the PP should be.

The numerical difference between the derived DP and the DP at the center of the flow range shall

. then be subtracted from or added to (as applicable) the actual measured DP for that test flow.

This should be done for all measured data to be used in the trend analysis. Below is an example:

PumpX Baseline data table Test Derived values for Point Flow DP allowed test range Qf 5300 - 5500 gpm 4 4768

75.2 5 5410 .,

59.2. 5500 56.24353 8 5400 58.9 Assume actual test measurements of 5362gpm / 60.3psid and 5465gpm / 56.6psid are being evaluated. The forecast DP at 5362 gpm is 59.89903 and the forecast DP at 5465 gpm is

.57.17065.

For the 5362 gpm reading: 60.3 - (59.8.9903 - 58.89245) = 59.29 For the 5465 gpm reading: 56.6 + (58.89245 - 57.17065) = 58.32 .

For the purposes of trending, the corrected values of 59.29 and 58.32 would be used for these two data points. Normalizing the DP in this manner eliminates the scatter that would be introduced by tests performed at flow values well above or below the reference flow .

Categorization of ADS Safety Relief Valves Purpose The purpose of this Technical Position is to establish the Hatch IST Program position for categorization of selected ,SRVs.

Applicability This Technical Position is applicable to the following SRVs which are aligned to the.

Emergency Core Cooling System (ECCS) Automatic Depressurization System (ADS) function:

Valve PIS No. Code Class Category P &ID Drawing Unit 1 / Unit 2 1B21-F013B 1 C H16062 1I32l-F013D 1 C B16062 1B2l-F013E 1 C H16062 1B21-F013F 1 C H16062 1B21-F013J 1 C H16062 1B21-F013K 1 C H16062 1B2l-F013L 1 C H16062 2B21-F013A 1 C H26000 2B21-F013C 1 C H26000 2B21-F0i3E 1 C H26000 2B21-F013H 1 C H26000 2B21-F013K 1 C H26000 2B21-F013L 1 C H26000 2B21-F013M 1 C H26000

,Justification The functions of these 14 ADS Safety Relief Valves (SRVs) are: 1) to act as a primary system safety relief valve which automatically actuates on high pressure; 2) to open upon receipt of an ECCS auto depressurization signal to reduce reactor pressure and; 3) to act as a primary system relief valve which can be manually actuated from the control room.

Even though these valves can operate as a result ofan electrical control signal, either automatic or manual, the actuation of the main valve is mechanically via a pilot valve.

The function of these valves is to reduce pressure. It is impractical to measure the stroke times for an SRV since the actual stem movement times are on the order of 100 msec.

Version 1.0 E. I. Hatch IST Program Page 15- 24

Technical Position TP-13 (Page 2 of 2)

Categorization of ADS Safety Relief Valves It is also impractical to exercise test these valves due to the need for reactor pressure for actuation and the need to control the resultant pressure transient.

Given their primary function, these valves will be treated as Category C safety relief valves and their testing will be as prescribed by ASME OM Code Appendix I.

Background

ASME OM Code Case OMN-21, Alternate Requirements for Adjusting Hydraulic Parameters to Specified Reference Points, provides guidance for adjusting reference flow/pressure to within a specified tolerance during Inservice Testing. The Code Case states "It is the opinion of the Committee that when it is impractical to operate a pump at a specified reference point and adjust the resistance of the system to a specified reference Version 1.0 E. I. Hatch IST Program Page 15- 26

Technical Position TP-14 (Page 2 of 3)

. Reference value testing ranges point for either flow rate, differential pressure or discharge pressure, the pump may be operated as close as practical to the specified reference point with the following requirements. The Owner shall adjust the system resistance to as close as practical to the specified reference point where the variance from the reference point does not exceed +

2% or - 1% of the reference point when the reference point is flow rate, or + 1% or - 2%

of the reference point when the reference point is differential pressure or discharge pressure. The NRC also discusses this ASME Code change in NUREG-1482, Revision 2, Section 5.3. Hatch obtained relief (see RR-PR-13) to implement this Code Case.

Position Hatch will perform pump Inservice Testing irt a manner consistent with the requirements as stated in ASME OM Code Case OMN-21. Specifically, testing of all centrifugal pumps identified above will be performed such that flow rate is adjusted as close as practical to the reference value and within proceduralized limits of +2% / -1 % of the reference value. For positive displacement pumps the discharge pressure will be adjusted as close as practical to the reference value and within proceduralized limits of+ 1% / -2%

of the reference value.

Hatch plant operators will still strive to achieve the exact test reference values during testing. Typical test guidance will be to adjust flow/pressure to the specific reference value with additional guidance that if the reference value cannot be achieved with reasonable effort the test will be considered valid if the steady state flow rate is.within the proceduralized limits of +2% / -1 % of the reference value or discharge pressure within proceduralized limits of+ 1% / -2% of the reference value.

,Justification This testing methodology allows for the throttling capability of tested systems while maintaining the ability to collect and analyze data which can identify degrading trends.

As discussed in NUREG 1482 Rev 2 Section 5.3 "The basis for allowing a variance of + 2 / -1 percent from the flow rate reference value deals with instrument fluctuations and system stability issues. The Code allows symmetrical damping devices or averaging techniques to be used to reduce instrument fluctuations to within 2 percent of the observed reading for values specified in the implementing procedures. Greater variances must be justified and acceptance criteria adjustments made as necessary. The limitation of 1 percent in the negative direction reduces the non-conservative impact on the variable parameter. The total 3 percent allowable variance provides for a reasonable throttling control range while minimizing the impact on trendability of the variable parameter.

Version 1.0 E. I. Hatch 1ST Program Page 15- 27

Technical Position TP-14 (Page 3 of 3)

Reference value testing ranges Licensees should ensure that performance trending of pumps is capable of detecting degradation as early as possible. Larger variances in the reference parameter will induce scatter in the variable parameter data. Techniques such as data normalization, where recorded test data is corrected by the known pressure to flow relationship, should be used when necessary to provide for accurate short term trending."

IST analysts should reconcile the impact of variance from the reference value when performing a trend analysis. Technical Position TP-12 provides guidance on the use of data normalization as a tool to eliminate data scatter due solely to reference value variance.
