CPNPP/IST Plan COMANCHE PEAK NUCLEAR POWER PLANT UNIT 1 & 2 INSERVICE TESTING PLAN FOR PUMPS & VALVES THIRD INTERVAL 1.0 GENERAL INFORMATION 1.1 Introduction Inservice Testing Plan for Pumps & Valves, hereafter referred to as the IST Plan, has been prepared to summarize the test program for certain pumps and valves pursuant to the requirements of the Code of Federal Regulations, 10CFR50.55a(f)(4); and as modified by Relief Request A-1, Request for Alternative from 10CFR50.55a(f)(4)(i) and (ii) for Inservice Testing Frequency Under 10CFR50.55a(a)(3)(i), and by the Nuclear Regulator Commission (NRC)

Safety Evaluation Report (SER) on the CPNPP RI-IST Program. This testing plan is applicable to CPNPP Units 1 & 2. The content and distribution of the IST Plan are controlled and users are cautioned to verify the control status of their copy prior to use. To obtain a copy of this document, contact Distribution Control at the Main Document Control Center. An electronic copy can be accessed via CPNPP Electronic License Basis Documents (CPNPP ELBD).

1.2 Code Edition and Addenda This IST Plan meets the requirements of the ASME OM Code 2004 Edition through 2006 Addenda, except in specifically identified instances where an alternative to the Code requirements is proposed or where it has been determined that conformance with certain Code requirements is impractical. In these instances, a request for relief from the Code requirement(s), including proposed alternatives to the requirement(s), has been prepared for Nuclear Regulatory Commission review and approval pursuant to 10CFR50.55a(a)(3) or (f)(5).

See Section 2.0, Inservice Pump Testing Plan, and Section 3.0, Inservice Valve Testing Plan for a more detailed discussion of Code edition.

1.3 Dates of Test Interval Implementation of the 1989 Edition IST Plan was completed on CPNPP Unit 1 before that unit was returned to power following the third refueling outage. This superceded the original Unit 1 Inservice Testing Plan for Pumps and Valves developed for the first inspection interval. The original Unit 1 IST Plan was implemented per the requirements of the 1986 Edition of Section XI. This 1989 Edition IST Plan constituted an update of the original Unit 1 IST Plan to a later approved Code edition as allowed by 10CFR50.55a(f)(4)(iv) and as approved by the NRC staff. This IST Plan was to remain in effect for Unit 1 for the 120 month interval following the date of the Unit 1 commercial operation (August 13, 1990).

An exemption from regulation 10CFR50.55a(f)(4)(ii) to the ten year test interval for Unit 1 was granted by the NRC on June 21, 1995. The extension allowed Unit 1 to remain under the 1989 Edition until the conclusion of the ten year test interval for Unit 2 (August 3, 2003).

COMANCHE PEAK - UNITS 1 AND 2 1-1 Rev. 0

CPNPP/IST Plan This IST Plan was in effect for Unit 2 for the 120 month interval following the date of the Unit 2 commercial operation (August 3, 1993 to August 2, 2003).

The IST Plan for Unit 1 and 2 first interval end date was extended from August 2, 2003 to not later than August 2, 2004 (see TXX-03075, dated April 11, 2003).

The risk informed inservice testing (RI-IST) was approved by the NRC on August 14, 1998 (Reference 10). The RI-IST Program was incorporated in the first interval program plan Rev. 15, and was implemented on December 4, 2000.

The start date IST Plan second interval for Unit 1 and 2 was August 3, 2004, and the end date for the second interval is August 2, 2013 (see TXX-04134).

The current start date of the third interval IST Plan for Unit 1 and Unit 2 is August 3, 2013, and the end date for the third interval is August 2, 2023.

1.4 Approval Status The first interval IST Plan was submitted to the NRC staff on July 2, 1992 via TXX-92302 requesting:

1. Approval to update the Unit 1 IST program to the requirements of the 1989 Edition of ASME Section XI as described in this IST Plan;

2. Approval of a proposed schedule for phasing in the implementation of this IST Plan for Unit 1; and,

3. Approval of the Relief Requests contained in Appendix A of this IST Plan for use in the testing of Unit 1 and Unit 2.

Relief Request A-1 and V-8 were submitted to the NRC for final approval Via TXX-98153. These relief requests allowed for risk informing IST.

By safety evaluation dated January 29, 1993 for Unit 1 and NUREG-0797, Supplemental Safety Evaluation Report (SSER) No. 26 dated February, 1993 for Unit 2, the NRC staff granted the following approvals.

1. Approval to update the Unit 1 IST program to the requirements of the 1989 Edition of ASME Section XI and approval to test Unit 2 to the requirements of the Code. (Approval had not specifically been requested to test Unit 2 to the requirements of the 1989 Code since regulation 10CFR50.55a already seemed to permit it; approval was granted nonetheless.)

2. Approval of the schedule described in Section 1.3 above for phasing in the implementation of this IST Plan for Unit 1.

3. Approval of the Relief Requests contained in Appendix A of this IST Plan for use in the testing of Unit 1 and Unit 2 with the exception of Relief Request V5 which was denied. (See Appendix A for specific information.)

COMANCHE PEAK - UNITS 1 AND 2 1-2 Rev. 0

CPNPP/IST Plan As pointed out in the safety evaluation and SSER, the NRC staff review of this IST Plan did not include verification that all pumps and valves within the scope of 10CFR50.55a and ASME Section XI (Now ASME OM Code) are contained in the IST program. Additionally, for the components included in the IST program, all applicable testing requirements were not verified.

COMANCHE PEAK - UNITS 1 AND 2 1-3 Rev. 0

CPNPP/IST Plan 2.0 INSERVICE PUMP TESTING PLAN 2.1 Scope The scope of the Inservice Pump Testing Plan is derived from the requirements of ASME OM Code 2004 Edition through 2006 Addenda, as modified by 10CFR50.55a(f)(4). As modified by Risk Informed IST Program Plan and previously NRC approved by Relief Request A-1. The pumps selected for inclusion in this testing plan are that ASME Class 1, 2 and 3 pumps which are provided with an emergency power source and are:

a) Required in shutting down a reactor to the safe shutdown condition, or b) Required in maintaining the safe shutdown condition, or c) Required in mitigating the consequences of an accident.

Excluded from this testing plan are:

a) Drivers, except where the pump and driver form an integral unit and the pump bearings are in the driver, and b) Pumps that are supplied with emergency power solely for operating convenience.

c) Skid mounted pumps that are tested as part of the major components and are justified to be adequately tested.

The pumps in the scope of this testing plan are described in the CPNPP Final Safety Analysis Report (FSAR), Section 3.9N.3.2 and 3.9B.3.2, Pump and Valve Operability Assurance and are tabulated in FSAR Tables 3.9N-9 and 3.9B-8, Active Pumps. This similar listing of pumps can be found in Table 0 of this IST Plan.

2.2 Pump Testing Table Format Detailed information and testing requirements for the pumps included in this IST Plan are summarized in Table 0. The guidance presented in References 1.5.2, 1.5.8 and 1.5.9 was used to the greatest extent possible in formatting this table.

Following is a discussion of the types of information presented in Table 0.

1. Pump Identification - The pump identification field includes the pump name (system name) and pump number. The pump name is the common noun name for the pump and conveys some sense of the pump function. The pump number is a unique identifier applied to each pump. Pumps are listed in Table 0 in alphabetical order by system name. See Flow Diagram M1-0200, Mechanical Symbols and Notes, for a discussion of pump numbering conventions and abbreviations. The pump names and COMANCHE PEAK - UNITS 1 AND 2 2-1 Rev. 0

CPNPP/IST Plan pump numbers shown in Table 0 are the same names and numbers used on the respective flow diagrams to identify the pumps.

2. Flow Diagram Number - The flow diagram number field indicates on which drawing the pump may be found. The flow diagram numbers are prefixed by M1 to indicate a Unit 1 drawing and by M2 to indicate a Unit 2 drawing. The suffix (if any) indicates the drawing sheet number.

3. Code Class - The code class field indicates the ASME Boiler and Pressure Vessel Code,Section III classification for the pump.

4. Pump Type - The pump type field indicates the classification of the pump.

The pumps are classified for the purpose of determining the Code required test parameters to be measured as well as for determining the Code limits for those test parameters. The pump classifications are taken from the Code itself.

Two basic pump classifications are used: centrifugal and positive displacement. Centrifugal pumps are further classified by the pump/driver arrangement and positive displacement pumps are further classified by the mechanical construction of the machine. The pump type acronyms are listed below along with their meanings.

C/DC (Centrifugal pump direct coupled to its driver): This is the most common centrifugal pump arrangement in which the pump and driver are mounted independent of each other (usually horizontally) and are connected by a flexible coupling. In this pump type, the pump and driver bearings are separate.

C/VLS (Centrifugal vertical line shaft pump): This arrangement is a special case of the direct coupled centrifugal pump. As the name suggests, the pump and driver are arranged vertically. However, unlike the typical direct coupled centrifugal pump, the vertical line shaft pump has a pumping element suspended at the end of a very long line shaft and has bearings which are inaccessible. Also, the vertical line shaft pump shares bearings with the driver in that the motor thrust bearing also acts as a thrust bearing for the pump.

C/DC/VLS (Centrifugal vertical line shaft direct coupled): This arrangement is also a special case of a vertically arranged pump. This pump has a short pump shaft, and has an accessible inboard bearing housing near the coupling end of the pump; the pump shaft and suction areas are inaccessible due to being submerged.

C/CC (Centrifugal pump close coupled to its driver): In this arrangement, no coupling is provided and the pump and driver form an integral unit. The pumping element is attached directly to the motor shaft and the pump bearings are actually the motor bearings. Orientation may be either horizontal or vertical.

COMANCHE PEAK - UNITS 1 AND 2 2-2 Rev. 0

CPNPP/IST Plan PD/RECIP (Reciprocating positive displacement pump): This is a positive displacement pump in which fluid is moved by a back and forth motion of the pressure-producing member(s). The output from a reciprocating pump will be pulsating and flow through the pump is controlled by integral check valves. (There are no reciprocating pumps in the CPNPP IST Plan.)

PD/ROT (Rotary positive displacement pump): This is a positive displacement pump in which fluid is moved by a rotating motion of the pressure-producing member(s). The output from a rotary pump is non-pulsating and flow through the pump is controlled by the geometry of the pump casing and rotor(s).

5. Test Parameters - The test parameters field indicates those quantities which the Code requires to be established or determined at each inservice test. The test parameters include speed, discharge pressure, differential pressure, flow rate and bearing vibration. Vibration is further classified as pump bearing vibration and driver bearing vibration. Not all test parameters are applicable to all pumps. Rather, the parameters to be established or determined for any pump are dependent on the pump type and are specified per the requirements of ASME OM Code 2004 Edition, through 2006 Addenda, Subsection ISTB. In Table 0, Code required test parameters are indicated with an X. Test parameters which are not applicable to a particular pump are indicated N/A. Required test parameters for which relief is requested are indicated by a footnote with the specific Relief Request number. (All pump and valve relief requests are contained in Appendix A of this IST Plan.)

6. Test Schedule - The test schedule field indicates the frequency of inservice tests for each pump in the RI-IST Plan. High Safety Significant pumps for which fluid inventory is normally provided are tested nominally every three months per the requirements of ASME OM Code 2004 Edition, through 2006 Addenda, Subsection ISTB-3400, and are indicated in Table 0 by 3 MO. High Safety Significant pumps lacking required fluid inventory (e.g., pumps in dry sumps) are tested at least once every two years per the requirements of ASME OM Code 2004 Edition, through 2006 Addenda, Subsection ISTB-3400, and are indicated in Table 0 by 2 YR.

Low Safety Significant pumps are tested nominally every six years (on a staggered test basis) unless indicated otherwise per the requirements of Relief Request A-1, and are indicated in Table 0 by 6 YR.

A (Group A pump test): Testing for pumps that are operated continuously or routinely during normal operation, cold shutdown, or refueling operations as defined by ISTB-5121, 5221 and Table ISTB-3000-1.

B (Group B pump test): Testing for pumps in standby systems that are not operated routinely except for testing as defined by ISTB-5122, 5322 and Table ISTB-3000-1.

COMANCHE PEAK - UNITS 1 AND 2 2-3 Rev. 0

CPNPP/IST Plan CPT (Comprehensive pump test): Testing for pumps as defined by ISTB-5123, 5223, 5323 and Table ISTB-3000-1.

7. Footnotes - Footnotes containing additional pump testing information are located at the back of Table 0 and are referenced in Table 0 by the footnote number in parentheses.

TABLE 0 - INSERVICE PUMP TESTING PLAN PAGE 7 of 7 NOTES

1. A risk informed - staggered test basis (RI-STB) shall be established for the pumps within the specified group.

2. Not Used.

3. The Fuel Oil Transfer Pumps were not commercially available as ASME BPV Code,Section III, Class 3; however, the normal commercial design was upgraded to equivalent ASME Section III, Class 3 quality requirements through seismic testing, qualification, and documentation.

4. The Residual Heat Removal Pumps were close coupled and all bearings were in the driver (motor); therefore, the driver was monitored for vibration. The pumps were modified to a direct coupled design and one set of radial bearings were installed in the pumps. The thrust bearing is still in the driver; therefore, it is prudent to take vibration at two points on the pump and five points on the driver.

5. Refer to Relief Request P-1 in Appendix A.

COMANCHE PEAK - UNITS 1 AND 2 CPNPP/IST Plan Rev. 0

CPNPP/IST Plan 3.0 INSERVICE VALVE TESTING PLAN 3.1 Scope The scope of the Inservice Valve Testing Plan is derived from the requirements of ASME OM Code 2004 Edition through 2006 Addenda, Subsection ISTC, Appendix I and Appendix II as modified by 10CFR50.55a(f)(4) and the Risk Informed IST Program Plan as allowed by previously NRC approved, Relief Request A-1. The valves selected for inclusion in this testing plan are those active or passive ASME Class 1, 2 and 3 valves and pressure relief devices (and their actuating and position indicating systems) which are required to perform a specific function:

a) In shutting down a reactor to the safe shutdown condition, or b) In maintaining the safe shutdown condition, or c) In mitigating the consequences of an accident.

Excluded from this testing plan are:

a) Valves used only for operating convenience such as vent, drain, instrument and test valves, or b) Valves used only for system control, such as pressure regulating valves, or c) Valves used only for system or component maintenance.

d) Skid mounted valves which are tested as part of the major component.

e) Category A and Category B Safety and Relief Valves are excluded from the requirements of ISTC-3700 and ISTC-3500, valve testing requirements.

Further, the valve actuating system test scope does not include external control and protection systems responsible for sensing plant conditions and providing signals for valve operation.

The active valves and pressure relief devices in the scope of this testing plan are described in the CPNPP Final Safety Analysis Report (FSAR), Sections 3.9N.3.2 and 3.9B.3.2, Pump and Valve Operability Assurance, and are tabulated in FSAR Tables 3.9N-10 and 3.9B-10, Active Valves. ASME Code Class 2 and 3 pressure relief devices that only protect systems/components that perform a safety function as described above are not tabulated in FSAR Tables 3.9N-10 and 3.9B-10. These valves will continue to be tested within the required test interval of 10 years during the third interval. Consistent with the philosophy discussed in Reference 1, these specific thermal relief valves do not require the two additional valve tests following as-found set-pressure determination failures. However, if COMANCHE PEAK - UNITS 1 AND 2 3-1 Rev. 0

CPNPP/IST Plan performance data indicates that more frequent testing is needed to assure valve function, then the testing frequency should be modified. In lieu of tests, valve replacement may be performed as an alternative to testing. This philosophy only applies to thermal relief valves whose only function is to protect systems/

components that have a safety function. These valves are identified in the IST Plan by having a safety function position listing of N/A.

The passive valves and pressure relief devices in the scope of this testing plan were identified by review and are those valves and pressure relief devices which perform a nuclear safety function but are not active and for which leakage testing or position indicator testing is required.

A listing of the above described active and passive valves and pressure relief devices can be found in Tables 1 through 19 of this IST Plan.

3.2 Valve Testing Table Format Detailed information and testing requirements for the valves included in this IST Plan are summarized in Tables 1 through 19. A separate table has been prepared for each plant system which contains valves in the scope of the plan.

The tables are arranged in alphabetical order by system name:

Auxiliary Feedwater Table 1 Component Cooling Water Table 2 Chilled Water (Safety & Non-Safety) Table 3 Chemical and Volume Control Table 4 Containment Spray Table 5 Demineralized and Reactor Makeup Water Table 6 Diesel Generator Auxiliaries Table 7 Feedwater Table 8 Main Steam Table 9 Reactor Coolant Table 10 Residual Heat Removal Table 11 Spent Fuel Pool Cooling Table 12 Safety Injection Table 13 Service Water Table 14 Ventilation (Control Room Air Conditioning) Table 15 COMANCHE PEAK - UNITS 1 AND 2 3-2 Rev. 0

CPNPP/IST Plan Vents and Drains Table 16 Miscellaneous Containment Isolation Valves Table 17 Safety & Relief Valves Table 18 Motor Operated Valves Table 19 The guidance in References 1.5.2, 1.5.8 and 1.5.9 was used to the greatest extent possible in formatting the tables. Following is a discussion of the types of information presented in the tables.

1. Valve Groups - Valves are grouped by system, safety significance, valve type, actuator type, manufacturer, model number. Each group has a unique Group Number to facilitate the implementation of the risk informed Inservice Test Program.

2. Valve Identification - Valve identification includes the valve number field and a brief description of the valve safety function (in the Remarks field).

In each table, the valves are arranged in numerical order by the four digit location number which forms the root of each valve number. See Flow Diagram M1-0200, Mechanical Symbols and Notes, for a discussion of valve numbering conventions and abbreviations. The valve numbers shown in Tables 1 through 19 are the same numbers used on the respective flow diagrams to identify the valves.

For valves which exist in both Unit 1 and Unit 2 and for which the test requirements are the same, the unit designator prefixes have been dropped from the valve numbers in the tables. The valve numbers in this case should be understood to be prefixed by 1 (or CP1) and 2 (or CP2),

as appropriate. If a valve is in a common system, exists in one unit only, is numbered differently between units or has different test requirements between units, then the unit designator is shown.

3. Flow Diagram Number - The flow diagram number field indicates on which drawing the valve may be found. The flow diagram numbers are prefixed by M1 to indicate a Unit 1 drawing and by M2 to indicate a Unit 2 drawing. The suffix (if any) indicates the drawing sheet number. Drawing coordinates are indicated in parentheses below the flow diagram number for ease in locating a valve.

4. Risk Ranking - A valve will either be ranked as High or Low Safety Significant. This was determined through the CPNPP Individual Plant Examination utilizing Probability Risk Assessment techniques and through the RI-IST Expert Panel.

5. Size - The size field indicates the nominal valve size in inches.

COMANCHE PEAK - UNITS 1 AND 2 3-3 Rev. 0

CPNPP/IST Plan

6. Code Class - The code class field indicates the ASME Boiler and Pressure Vessel Code,Section III classification for the valve.

7. Category - The category field indicates the classification of the valve according to characteristics described in 2004 Edition through 2006 Addenda, Subsection ISTC-1300. See the Valve Table Index at the end of this section for a listing of valve categories and their meanings.

8. Function - The function field indicates the manner in which a valve accomplishes its required safety function(s). A denotes an active valve and P denotes a passive valve with the terms defined as follows:

Active valves - valves which are required to change obturator position to accomplish their required safety function(s).

Passive valves - valves which maintain obturator position and are not required to change obturator position to accomplish their required safety function(s).

Obturator - valve closure member (disk, gate, plug, ball, etc.)

9. Safety Function Position - The safety function position field indicates the position (open or closed) to which a valve must move or remain in to accomplish its required safety function(s). The open and closed positions are indicated by O and C respectively.

10. Test Parameters/Schedule - The test parameters/schedule field denotes the Code test requirements and test frequencies for valves in the IST Plan.

The test parameters include leak test, exercise test, fail-safe test and position indicator test. Not all test parameters are applicable to all valves.

Rather, the parameters to be tested for any valve are dependent on the valve/actuator type, category, and function. Valves which have both an open and closed safety function position and for which the test requirements or frequencies are different in the two positions, have their open and closed test requirements identified separately. Test parameters which are not applicable to a particular valve are indicated N/A.

Check valves are exercise tested in both the open and closed direction regardless of safety function position or valve safety significance. Non-safety function exercise tests for high safety significant check valves shall be performed at least once every two years. Non-safety function exercise tests for low safety significant check valves shall be performed at the frequency specified in Relief Request A-1.

Required test parameters or test frequencies for which relief is requested are indicated by the specific Relief Request number. (All pump and valve relief requests are contained in Appendix A of this IST Plan.) In cases where the performance of a valve full-stroke exercise test is limited to cold shutdowns or refueling outages, a table footnote is provided which justifies COMANCHE PEAK - UNITS 1 AND 2 3-4 Rev. 0

CPNPP/IST Plan this determination. See the Valve Table Index at the end of this section for a listing of test parameter and schedule acronyms and their meanings.

11. Footnotes - Footnotes containing additional valve testing information are located at the back of each system valve table and are referenced in the tables by the footnote number in parentheses.

Category B - Valves for which seat leakage in the closed position is inconsequential for fulfillment of their required safety function(s).

Category C - Valves which are self-actuating in response to some system characteristic, such as pressure (relief valves) or flow direction (check valves), for fulfillment of their required safety function(s).

Category D - Valves which are actuated by an energy source capable of only one operation, such as rupture disks or explosively actuated valves, for fulfillment of their required safety function(s). (There are no Category D valves or pressure relief devices in the CPNPP RI-IST Plan.)

Note: Seat tightness determination is performed as part of the performance test for Category C pressure relief devices (SRV) and may be performed as a method of close exercise test for check valves (CV). However, pressure relief devices and check valves are further classified as Category A only if there is a safety analysis criteria existing for valve seat leakage such as for pressure relief devices or check valves performing containment Rev. 1 isolation functions or reactor coolant system pressure isolation functions.

1. A risk informed - staggered test basis (RI-STB) shall be established for the valves within the specified group.

2. X-PCV-H116A, -H116B, UPS A/C Condenser Cooling Flow Control Valves; These valves are exempt from Inservice Testing per ASME OM Code 2004 Edition, through 2006 Addenda, Subsection ISTC-1200. However, the valves are fail open by accumulators. Therefore the fail open function is required to be tested per NUREG-1482 Rev. 1 paragraph 4.2.9.

PV-4552, -4553, Safety Chilled Water Condenser Cooling Flow Control Valves:

These valves are included in the IST program based on PRA HSSC ranking (ER-EA-010 Rev. 2). These are exempt from the ASME OM code per ISTC 1200. The valves safety function is to modulate to control temperature. The valves are fail open by design, however they are not fail safe. Air accumulators are required to perform safety COMANCHE PEAK - UNITS 1 AND 2 function of low temperature control upon loss of instrument air. Thus the testing should be commensurate with the safety significance. Therefore, a full stroke PIT and Fail-Open test should be done every 18 months. Since this is a self-revealing, in-process failure mode for normally operating equipment, this is considered an adequate test and is a conservative approach.

TABLE 4 - CHEMICAL AND VOLUME CONTROL PAGE 8 of 8 NOTES

1. A risk informed - staggered test basis (RI-STB) shall be established for the valves within the specified group.

2. 8152, 8160, Letdown Line Containment Isolation Valves; are full-stroke closed exercised at cold shutdowns. These valves cannot be full-stroke close exercised during plant operation because closing the valves isolates letdown flow from the RCS. In that letdown flow is used to preheat charging flow, isolation of letdown will cause thermal transients on the RCS charging nozzles, the regenerative heat exchanger and the letdown heat exchanger for which they are not designed. The subject power operated valves cannot be part-stroke close exercised during plant operation. In the case of 8152, 8160, their stroke times are so short that any part-stroke exercise attempt would effectively be a full-stroke and thus is not performed for the reasons given above.

3. 8546, Charging/High Head Safety Injection Pumps Suction from the RWST Check Valve, full-stroke open exercised at refueling outages and full-stroke close exercised at COMANCHE PEAK - UNITS 1 AND 2 cold shutdowns. (Part-stroke close exercising is not applicable.) This valve cannot be full or part-stroke exercised during plant operation because initiating flow through this valve introduces high concentration boric acid to the RCS via the charging system resulting in a reactivity transient and possibly a reactor shutdown. Further, during plant operation the high RCS pressure will not allow the maximum required injection flowrate to be achieved. The valves cannot be full-stroke exercised at cold shutdowns because the high flowrates required could challenge the RCS Cold Overpressure Mitigation System as well as impose hydraulic transients on the charging system and on the Reactor Coolant Pump seals which can cause them to cock.

4. Charging service is alternated approximately every refueling outage between the normal charging line (containing check valves 8378A and 8378B) and the alternate charging line (containing check valves 8379A and 8379B) such that neither flowpath will be exposed to more than 60% of the thermal transients associated with stoppage CPNPP/IST Plan and restart of charging flow. In accordance with ASME OM Code 2004 Edition, through 2006 Addenda, Subsection ISTC-3510, the pair of check valves in the charging line which is out of service need not be open exercise tested as they are only relied on to perform their open boration path function when they are designated to be in service.

However, they must have a valid, current open exercise tested prior to placing the charging line back in service.

The check valves in both the normal and alternate charging lines are relied on to perform their closed reactor coolant pressure boundary function at all times when this function is required. Therefore, the close exercise test schedule must be maintained for all four check valves, regardless of which charging line is designated to be in service.

5. Not Used.

6. ISTC-3550 Valve in Regular Use - This valve operates in the course of plant operation at a frequency that satisfies the requirements of this IST Plan.

TABLE 5 - CONTAINMENT SPRAY PAGE 4 of 4 NOTES

1. A risk informed - staggered test basis (RI-STB) shall be established for the valves within the specified group.

2. CT-0142, CT-0145, Containment Spray Header Check Valves; CT-0148, CT-0149, Containment Spray Pump Suction Check Valves from the Recirculation Sumps, are disassembled at refueling outages to verify operability. Full or part-stroke exercising these valves with flow is not practicable. In the case of CT-0142 and CT-0145, the flowpath downstream of the valves is open to the Containment Building via the spray headers. No meaningful flow can be achieved through these valves without deluging the Containment and causing a significant cleanup problem and potential equipment damage. In the case of CT-0148 and CT-0149, the flowpath upstream of the valves is open to the normally dry Containment Recirculation Sumps. Sump inventory only exists post-accident when the RWST has been depleted. Flooding the sumps for test purposes would introduce contaminants into the Containment Spray System and the RWST which otherwise contain reactor quality water. Additionally, sump makeup COMANCHE PEAK - UNITS 1 AND 2 would be required at a high rate to protect the Containment Spray Pumps from a loss of suction.

3. This valve has a water filled loop seal and is not required to be leakrate tested (see DBD-ME-013, Rev. 22, Attachment 1, Note 3).

TABLE 8 - FEEDWATER PAGE 7 of 7 NOTES

1. A risk informed - staggered test basis (RI-STB) shall be established for the valves within the specified group.

2. FW-0070, FW-0076, FW-0082, and FW-0088, Main Feedwater Header Check Valves, are disassembled at refueling outages to verify operability as allowed by ASME OM Code, 2004 Edition, through 2006 Addenda, Subsection ISTC-5220. Full or part stroking these valves is not practical. Leak testing of the valves has proven to be impractical due to the insufficient amount of test makeup available versus the valves size. Pursuant to Generic Letter 89-04 and NUREG-1482, verification of the operability of the subject check valves will be performed through disassembly and inspection of one of the four valves at each refueling outage for each unit. The disassembled valve will be verified to be capable of full-stroking and it will be verified that the internals of the valve are structurally sound (no loose or corroded parts). Also, the disk will be manually exercised. Each valve will be disassembled, inspected and manually full-stroke exercised on a rotating basis at each refueling outage until the entire group has been tested. If the disassembled valve is not capable of being full-stroke exercised or there is binding or failure of valve internals, the remaining valves in the group in that unit will also be tested during the same outage. Once this is completed, the sequence of disassembly will be repeated unless extension of the interval can be justified.

3. FCV-0510, FCV-0520, FCV-0530, FCV-0540, Feedwater Regulating Valves are full-stroke exercised at cold shutdowns. These valves cannot be full-stroke exercised COMANCHE PEAK - UNITS 1 AND 2 during plant operation because closing the valves interrupts feedwater flow resulting in severe steam generator level transients and, most likely, a turbine and reactor trip.

4. The ISTC-3550 Valve in Regular Use - This valve operates in the course of plant operation at a frequency that satisfies the requirements of this IST Plan.

5. FW-0013, FW-0016, FW Line Section Sample Isolation Valves, are manual containment isolation valves. These valves are locked closed to establish containment isolation and AFW operability. There is no operational need to cycle these valves (passive).

6. The exercising of these valves during normal operation would cause an interruption of feedwater to the steam generators. CPNPP/IST Plan

7. The feedwater check valves in the auxiliary feedwater lines to the steam generator open to provide the AFW flowpath during design basis events. These valves must close in the event of a line break upstream of the outboard check valve in order to terminate a Condition III loss of feedwater event. In addition, these valve se also must close post-LOCA to protect the cold containment penetration during intermittent operation of AFW.

TABLE 10 - REACTOR COOLANT PAGE 3 of 3 NOTES

1. A risk informed - staggered test basis (RI-STB) shall be established for the valves within the specified group.

2. SI-0166, SI-0167, SI-0168, SI-0169 are part of Safety Injection System but are included in this table because they are more closely associated with Reactor Coolant System.

3. 2-HV-3607 & 2-HV-3608, Reactor Head Vent Valves, are full-stroked exercised at cold shutdowns. These valves cannot be full-stroke exercised during plant operation because cycling the valves introduces the unnecessary risk of inadvertently opening an RCS vent path. Also, attaching a hose to the vent lines to control the effluent while stroking cannot reasonably be done while the plant is at power. The stroke length (and stroke time) of these valves is so short that any part-stroke exercise attempt would effectively be a full-stroke and thus is not performed for the same reasons.

4. ISTC-3510 Exercising Test Frequency - Power-operated relief valves shall be tested once per fuel cycle. PCV-0455A & PCV-0456, Pressurizer Power Operated Relief Valves, are full-stroke exercised at cold shutdowns. These valves cannot be full-stroke exercised during plant operation because cycling the valves introduces the unnecessary risk of inadvertently opening an RCS vent path which would result in a design basis event. The stroke length (and stroke time) of these valves is so short that COMANCHE PEAK - UNITS 1 AND 2 any part-stroke exercise attempt would effectively be a full-stroke and thus is not performed for the same reasons.

5. ISTC-3560 Fail-Safe Valves - Valves with fail-safe actuators shall be tested in accordance with the exercising frequency in ISTC-3510.

6. ISTC-3550 Valve in Regular Use - This valve operates in the course of plant operation at a frequency that satisfies the requirements of this IST Plan.

TABLE 13 - SAFETY INJECTION PAGE 12 of 13 NOTES

1. A risk informed - staggered test basis (RI-STB) shall be established for the valves within the specified group.

2. The test frequency requirements of Technical Specification SR 3.4.14.1 apply for leak testing of 8815; 8818A, B, C, D; SI-8819A, B, C, D; 8841A, B; SI-8900A, B, C, D; SI-8905A, B, C, D; 8948A, B, C, D; 8949A, B, C, D; 8956A, B, C, D. The Technical Specification SR 3.4.14.1 test frequency requirements are more restrictive than the test frequency requirements of ASME OM Code 2004 Edition, through 2006 Addenda, Subsection ISTC-3630.

3. 8815 High Head Safety Injection Flowpath Check Valve; SI-8819A, B, C, D, 8926, 8969B, 8922A, B, and SI-8905A, B, C,D, 8949A and D Intermediate Head Safety Injection Flowpath Check Valves are full-stroke exercised at refueling outages. These valves cannot be full stroke open exercised during plant operation or during cold shutdowns because the flowpaths discharge into the RCS.

In the case of the High Head subsystem, the valves cannot be full-stroke exercised during plant operation because the high RCS pressure will not allow the maximum required injection flowrate to be achieved.

COMANCHE PEAK - UNITS 1 AND 2 In the case of the Intermediate Head subsystems, the valves cannot be full stroke exercised during plant operation because the relatively higher pressure of the Reactor Coolant System will not allow forward flow through these paths. (An exception to this is valve 8926 which lies in the SI Pumps miniflow path and thus is part-stroke open exercised quarterly during pump tests.) The check valves in the intermediate head injection paths cannot be full-stroke exercised at cold shutdowns using the Safety Injection Pumps because the resulting high flowrates and pressures could challenge the RCS Cold Overpressure Mitigation System. This leak testing is not practicable to perform at cold shutdowns due to its complexity and critical path nature. Such testing would prevent the immediate return of a shutdown unit to power operation which is contrary to the intent of ASME OM Code 2004 Edition, through 2006 Addenda, Subsection ISTC-3522.

The subject check valves are full-stroke close exercised at refueling outages at the same frequency as the full-stroke open exercise for the reasons described above.

CPNPP/IST Plan (Close exercising of valve 8926 is not practicable following its quarterly part-stroke open exercise. To do so would defeat both trains of the intermediate head subsystem.

Therefore valve 8926 is also full-stroke close exercised at refueling outages coincident with its full-stroke open exercise.)

4. Beginning with the fifth refueling outage for Unit 1 and the third refueling outage for Unit 2, valves 8956A, B, C, and D will be tested consistent with guidelines in Section 4.1.2 Exercising Check Valves with Flow and Nonintrustive Techniques, of NUREG-1482, Rev. 1 Guidelines for Inservice Testing at Nuclear Power Plants. Relief from the ASME Code is not required because this method is considered other positive means of verifying disk movement.

5. 8818A, B, C, D, 8841A, B, 8948A, B, C, D, 8949B, C, Low Head Safety Injection Flowpath Check Valves, are full-stroke exercised at refueling outages to verify operability.

These valves cannot be full or part-stroke open exercised during plant operation because the relatively higher pressure of the Reactor Coolant System will not allow forward flow through these paths. Part-stroke exercising of these check valves during plant operation via the SI test header is not practicable because this path yields flowrates too small (approximately 5 gpm) to be meaningful for assessing the operational readiness of these valves. It is not practicable to full stroke exercise these valves at cold shutdowns because the acoustic emission testing needed to verify the valves go full-open requires both Residual Heat Removal Pumps running and all Reactor Coolant Pumps secured to perform a satisfactory test. Both Residual Heat Removal Pumps are required to flow through a single SI header to achieve the hydraulic transient necessary to create the acoustic signature. During the test Residual Heat Removal flow must be secured. The Reactor Coolant Pumps must be secured to lower background noise sufficiently to record the acoustic signature.

Non-intrusive testing techniques, such as the acoustic emission method applied here is considered other positive means as defined in ASME OM Code 2004 Edition, through 2006 Addenda, Subsection ISTC-3520. During the initial acoustic emission testing for these valves, the system flow conditions were established to cause the valves to fully stroke. During subsequent testing, all valves shall be fully stroked at repeatable system conditions. The acoustic emission monitoring of the valves, however, Rev. 0

TABLE 13 - SAFETY INJECTION PAGE 13 of 13 will only be performed on one valve per group per outage on a rotating schedule each time testing is performed (a sampling program). The groups will be four valves each, 8818A, B, C, D, and 8948A, B, C, D. If problems are found with the sample valve, all valves in the affected group must be tested using acoustic emission monitoring during the same outage. An alternative would be to perform acoustic emission testing on all valves listed above instead of measuring flow conditions. Either method is acceptable.

The subject check valves are full-stroke close exercised at cold shutdowns because acoustic emission monitoring is not required for these tests.

1. A risk informed - staggered test basis (RI-STB) shall be established for the valves within the specified group.

2. 1BS-0015, 1BS-0029, 1BS-0044, 1BS-0056 are non-ASME valves. However, they are included in the Inservice Valve Testing Plan in accordance with Generic Letter 89-04, Attachment 1, Position 10 because they are containment isolation valves which are included in the 10CFR50 Appendix J Program.

3. 2BS-0015, 2BS-0029, 2BS-0044, 2BS-0056 are relief valves and therefore would normally be classified as Category A/C. In this application, however, they are being used as lever operated manual valves which spring return to closed and not for self-actuated overpressure relief. For this reason they are classified as Category A.

4. ISTC-3550 Valve in Regular Use - This valve operates in the course of plant operation at a frequency that satisfies the requirements of this IST Plan.

TABLE 18 - SAFETY & RELIEF VALVES PAGE 15 of 15 NOTES

1. These valves meet the scoping requirement of ISTA-1100(b) for relief devices that protect systems or portion of systems that perform one or more of the three safety functions (shutdown the reactor to the safe shutdown condition, maintain the safe shutdown condition, or mitigate the consequences of an accident). Additionally, these relief valves meet the criteria of ASME OM CODE 2004 Edition through 2006 Addenda, I-1390 Test Frequency, Class 2 and 3 Pressure Relief Devices That Are Used for Thermal Relief Application. These thermal relief valves shall be tested every 10 years, unless performance data indicate more frequent testing is necessary. In lieu of tests, relief valves may be replaced at frequency of every 10 years, unless performance data indicate more frequent replacement is necessary. No additional valves are required to be tested if a thermal relief valve exceeds its as-found set pressure tolerance.

2. 8708A and 8708B, RHR Suction Relief Valves, are Passive and are therefore exempt from performance 2004 through 2006 Addenda, Subsection ISTC, Table ISTC-3500-1.) Technical Specification LCO 3.4.12, however, allows crediting these valves for LTOP protection in MODES 4, 5, 6. Therefore, these valves are performance tested to the requirements of ASME OM Code 2004 Edition, through 2006 Addenda, Appendix I.

5. MOV HV-8402A is a passive valve with open safety function for boration flowpath. The design function of HV-8402A is to isolate and bypass HCV-0182 during maintenance and in case of a fire to ensure that the normal charging path is isolated. Since the function to close during a fire is important to safety, HV-8402A will be exercise tested open and closed.

CODE CLASS See Tables 0 through 19.

CATEGORY See Tables 0 through 19.

COMPONENT NO. & See Tables 0 through 19. This change affects all current components COMPONENT in the CPNPP Inservice Testing (IST) Plan, and also adds some new DESCRIPTION components to the RI-IST Plan.

DESCRIPTION Risked Informed - Inservice Testing, Alternative from 10CFR50.55a(f)(4)(i) and (ii) for Inservice Testing Frequency: This alternative utilizes a risk-based approach to change the test frequencies of certain low safety significant components (LSSCs) in the ASME OM Code pump and valve inservice testing (IST) Program.

The extended frequencies are greater than those currently allowed by the ASME OM Code. The process used to identify candidates for frequency extension is discussed under Proposed Alternative and Basis for Alternative.

CURRENT TEST Test frequencies of 2 years or less, the specified frequency for each REQUIREMENTS inservice test is met if the test is performed within 1.25 times the interval specified in frequency. For test frequencies greater than 2 years, the specified frequency for each inservice test is met if the test is performed with the interval specified in frequency (1.25 times interval does not apply).

Regulation 10 CFR 50, Section 50.55a(f)(4)(i) states; Inservice tests to verify operation readiness of pumps and valves, whose function is required for safety, conducted during the initial 120-month interval must comply with the requirements in the latest edition and addenda of the Code incorporated by reference in paragraph (b) of this section on the date 12 months prior to the date of issuance of the operating license subject to the limitations and modifications listed in paragraph (b) of this section.

Regulation 10 CFR 50, Section 50.55a(f)(4)(ii) states; Inservice tests to verify operation readiness of pumps and valves, whose function is required for safety, conducted during successive 120-month interval must comply with the requirements in the latest edition and addenda of the Code incorporated by reference in paragraph (b) of this section 12 months prior to the start of the 120-COMANCHE PEAK - UNITS 1 AND 2 A-2 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES month interval, subject to the limitations and modifications listed in paragraph (b) of this section.

The ASME Code of record for CPNPP is the ASME OM Code 2004 Edition through 2006 Addenda. The Code specifies the following test frequencies:

Test Type Test Frequency (nominal) Code Reference Pump Test 3 months OM ISTB Valve Position Indication 2 years OM ISTC Verification Valve Exercising Test 3 months OM ISTC Valve Fail-Safe Test 3 months OM ISTC Valve Leak Rate Test 2 years OM ISTC (Non-Containment Isolation Valves)

Check Valve Exercise Test 3 months OM ISTC Safety/Relief Valve Setpoint Test 5 years OM Appendix I (class 1, class 2 MSSV) 10 years (class 2, 3) OM Appendix I PROPOSED In lieu of performing inservice tests on pumps and valves whose ALTERNATIVE function is required for safety at frequencies specified in the ASME Code, as required by 10 CFR 50.55a(f)(4)(i) during the 120-month operating interval, this alternative would allow the inservice test frequencies of those pumps and valves to be determined in accordance with an NRC approved Risk-Informed IST Program Description at CPNPP as follows:

(1) The safety significance of pumps and valves whose function is required for safety will be assessed in accordance with the NRC approved Risk-Informed IST Program Description. These components will be classified as either High Safety Significant COMANCHE PEAK - UNITS 1 AND 2 A-3 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES Components (HSSCs) or Low Safety Significant Components (LSSCs). The inservice testing of those components classified as LSSC will be performed at extended test frequencies determined in accordance with the Risk-Informed IST Program Description. The inservice test methods for all pumps and valves whose function is important to safety will continue to be performed in accordance with the ASME Code.

(2) The safety significance assessment of pumps and valves will be updated, as specified in the Risk-Informed IST Program Description.

This alternative will also apply to 10CFR50.55a(f)(4)(ii) for successive 120-month IST intervals.

See Attachment 1 for the Risk-Informed Inservice Testing Program Description.

BASIS FOR Section 50.55a(a)(3) of 10 CFR states in part:

ALTERNATIVE Proposed alternatives to the requirements of paragraphs (c), (d), (e),

(f), (g), and (h) of this section or portions thereof may be used when authorized by the Director of the Office of Nuclear Reactor Regulation.

The applicant shall demonstrate that: (i) The proposed alternatives would provide an acceptable level of quality and safety.

TU Electric requests NRC approval to implement the Risk-Informed Inservice Testing Program Description as an alternative to the requirements of 10 CFR 50.55a(f)(4)(i) and (ii). These regulations require that inservice tests on pumps and valves, whose function is required for safety, must comply with a specified ASME Code.

Specifically, TU Electric requests approval to utilize a risk-Informed inservice testing program to determine inservice test frequencies for valves and pumps that are identified as low safety significant, in lieu of testing those components at the frequencies specified in the ASME Code. The use of the Risk-Informed Inservice Testing Program Description will provide an acceptable level of quality and safety.

The current Code is based on a deterministic approach which considers a set of challenges to safety and determines how those challenges should be mitigated. The deterministic approach contains elements of probability, such as the selection of accidents to be analyzed as design basis accidents (e.g., the reactor vessel rupture is considered too improbable to be included) and the requirements for emergency core cooling (e.g., safety train redundancy).

COMANCHE PEAK - UNITS 1 AND 2 A-4 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES The Risk-Informed IST Program that would be implemented with this alternative incorporates a probabilistic approach to regulation which enhances and extends this traditional, deterministic approach, by:

(1) allowing consideration of a broader set of potential challenges to safety, (2) providing a logical means for prioritizing these challenges based on risk significance, and (3) allowing consideration of a broader set of resources to defend against these challenges.

First, the PRA model has identified a broader set of challenges to safety. The Risk-Informed Inservice Testing Program identified High Safety Significant Components (HSSCs) which were not in the previous ASME IST Program. Even though the components are outside the ASME Code class boundary, they will be tested commensurate with their safety significance. Where the ASME OM Code testing is practical, HSSCs not in the current ASME IST Program Plan will be tested in accordance with Appendix I for safety relief valves, Subsection ISTC for active valves and Subsection ISTB for pumps. Where ASME OM Code testing is not practical, alternative methods will be developed to ensure operational readiness.

Components in the current ASME IST Program which are determined to be HSSCs will continue to be tested in accordance with the current Program, which meets the requirements of the ASME OM Code, except where specific written relief has been granted. Components in the current ASME IST Program which are determined to be LSSC will also be tested in accordance with the ASME IST Program, except that the test frequency will initially be extended to once every 6 years. The extended test frequency will be staggered over 6 years as described in Attachment 1. No LSSC will be deleted from the ASME IST Program.

Second, the Risk-Informed Inservice Testing Program prioritizes these challenges based on the results of the CPNPP PRA. The risk rankings are then complemented with rankings based on consideration of other accident initiators (e.g. fires, tornadoes, and earthquakes) and plant operating modes. These rankings considered importance with respect to core damage prevention, and prevention of large early releases of radiation to the public. Attachment 1 (pages 5 through 20 of Enclosure 1 to TXX-98086) describes the program methodology.

Enclosure 3 to TXX-96371 (TU Electric letter dated June 3, 1996, from C. L. Terry to the NRC) provides the current list of LSSCs from the initial implementation of that methodology.

COMANCHE PEAK - UNITS 1 AND 2 A-5 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES Third, an Integrated Decision Process (IDP) allows a broader set of resources to be considered to defend against challenges to safety.

The IDP is composed of experienced individuals with expertise in the areas of ASME Code, plant operations, maintenance engineering, system engineering, design engineering, and probabilistic risk assessment. The IDP is responsible to ensure the risk ranking input information is consistent with plant design, operating procedures, and with plant-specific operating experience. At the end of the IDP review process every component in the CPNPP ASME IST Program is reviewed.

The risk-informed process will assure that a defense-in-depth philosophy is maintained.

As a living process, components will be reassessed periodically to reflect changes in plant configuration, component performance, test results, industry experience, and other factors. When the list of components is affected, changes will be provided to the NRC in regular Program updates.

There could be safety enhancements obtained by focusing resources on HSSCs and reducing the testing frequency on LSSCs. Extensive testing on LSSCs could have an adverse effect on safety. Reduction of testing should reduce component wear-out, operator burden, system unavailability, cost of testing, and radiation exposure.

Reduced testing could also achieve a more optimum balance between the positive impacts of testing and the negative effects of disturbing equipment from service and entering less than optimum plant configuration, such as valve misalignments.

RADIOLOGICAL Potential radiation exposure will be diminished due to less frequent CONCERNS (ALARA) testing.

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1 RISK-INFORMED INSERVICE TESTING PROGRAM DESCRIPTION (RI-IST)

The proposed alternative is a risk informed process to determine the safety significance and testing strategy of components in the ASME Inservice Testing (IST) Program, and identify non-ASME IST components (pumps & valves) modeled in the Probabilistic Risk Analysis (PRA) that are determined to be High Safety Significant Components (HSSCs). The process consists of the following elements.

1) Utilization of the Probabilistic Risk Analysis (PRA) techniques to identify component importance measure values. (PRA Techniques)

2) Categorize components based on importance measures determined by the PRA techniques. (Component Risk Category)

3) Blended deterministic and probabilistic data to perform a final importance ranking of components and categorization as either Low Safety Significant Component (LSSC) or High Safety Significant Component (HSSC). (Integrated Decision Process) (IDP)

4) Develop/Determine Test Frequencies and Test Methodologies for the IST components. (Testing Philosophy)

5) Evaluate the cumulative impact of the test frequency changes on total plant risk (i.e., CDF and LERF) to ensure that the change in plant safety is within the acceptable range. (Cumulative impact)

6) Develop an implementation plan. (Implementation)

7) Develop a Corrective Action plan. (Corrective Action)

8) Perform periodic reassessments. (Periodic Reassessments)

9) Methodology for making changes to the RI-IST. (Changes to RI-IST Program after Initial NRC Approval)

1) PRA Techniques PRA methods will be used to determine the risk significance of components based on end states of interest, such as core damage frequency (CDF) and release of radioactivity (e.g.

large early release frequency (LERF)).

The PRA techniques are used in conjunction with the Integrated Decision Process (IDP) to ensure that all the available information is accounted for in developing the importance measures. As such, a review of plant equipment and operating procedures will be performed to identify potential plant specific initiating events as well as those initiating COMANCHE PEAK - UNITS 1 AND 2 A-7 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1 events that have been identified in the Nuclear industry. Evaluation of initiating events will also include loss of support systems and other special initiators.

Any changes to the PRA models used for the development of importance measures for the RI-IST will be independently reviewed. The independent reviews will be by either the in-house personnel or outside consultants.

The PRA will be periodically evaluated (See Section 8) to reflect the current plant design, procedures, and programs. Also the PRA will be evaluated prior to moving components to the LSSC category.

A full scope PRA is not required. However, any limitations (e.g. missing initiating events) will be addressed by the IDP using the methodology described in Section 2 below.

The potential degradation of components will be considered in the overall assessment of risk associated with the implementation of the RI-IST. As a result, any effect on common cause failure estimations will also be evaluated. To the extent possible, plant-specific data will be utilized to assess component degradation.

Compensatory measures which are used as part of the IDP process to qualitatively justify the extension of test interval will be re-verified during the IDP process update (See Section 8).

2) Component Risk Category Two figures of merit will be used to initially determine the risk categories of IST components. These two methods are Fussell-Vesely (FV) and Risk Achievement Worth (RAW). For the RI-IST Program, the following criteria will be used to initially rank components for review by the Integrated Decision Process (IDP).

Category Criterion High FV > 0.001 Potentially High FV < 0.001 and RAW > 2 Low FV < 0.001 and RAW < 2 The CDF and LERF for the change are within the acceptance guidelines of Regulatory Guide 1.174.

COMANCHE PEAK - UNITS 1 AND 2 A-8 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1 Methodology/Decision Criteria for Limited Scope PRA The following describes the methodology used to categorize components in the RI-IST when the program is reassessed. However, only those elements that are significantly affected by the model changes (e.g., design modifications or procedural changes) need to be reviewed in detail using this process. The scope of the review and the justification for it will be documented as part of the IDP.

Apply Importance Criteria to PRA and Review Review FV and RAW importance measures for pumps and valves considered in the PRA against the criteria and determine if the grouping of components is logical.

Review component importance measures to make sure that their bases are well understood.

Robustness/Validation of Results

Address the sensitivity of the results to common cause failures (CCF),

assuming all/none of the CCF importance is assigned to the associated component.

Evaluate the sensitivity due to human action modeling. Identify/evaluate operator actions omitted by the PRA that can change the ranking of a component. The omitted recovery actions are those not credited because they are not important to the CDF.

Consider industry history for particular IST components. Review such sources as NRC Generic Letters, SOERs, IOERs and Technical Bulletins and rank accordingly.

For components with low FV/high RAW ensure that other compensatory measures are available to maintain the reliability of the component.

Identify and evaluate components whose performance shows a history of causing entry into LCO conditions. To ensure that safety margins are maintained, consider retaining the ASME test frequency for these components.

Ensure that truncated components have been eliminated due to redundancy of function rather than solely due to reliability. If they are truncated due to their high reliability, then those components should be qualitatively re-evaluated and re-categorized appropriately.

COMANCHE PEAK - UNITS 1 AND 2 A-9 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1 Validate or change the PRA-based component ranking. If the validated PRA ranking is high, rank the component high; if the PRA ranking is low and the other factors such as the operating performance of the component validate the ranking, rank as low.

Fire, Tornado and Seismic Considerations Consider the following for risk ranking components for external events.

Calculate risk importance measures for components in the fire and tornado cutsets. Compare these calculated values and the PRA values to identify those components that are low risk significant for the PRA but high risk significant for fire and tornado.

Review component importance measures and the PRA limitations for fire and tornado in a manner similar to that described for internal events discussed above and adjust the rankings of the components accordingly.

For those components on the Safe Shutdown Equipment List (SSEL) and the containment systems list, review their risk categories to ensure that those components important to seismic and containment integrity are appropriately categorized.

Outage Risk Importance A qualitative assessment of PRA systems modeled for shutdown modes will be performed to determine the impact of shutdown modes on IST rankings. To perform this analysis a three step process will be used. First, using existing PRA system models as the basis, components and system configurations that are unique to the shutdown modes from the at power PRA will be identified. Second, using a qualitative set of rules, components in key trains will be ranked into three categories:

1. Category 1: High safety significant components (high FV)

2. Category 2: Potentially high safety significant components (low FV, moderate to high RAW).

3. Category 3: Low safety significant components (low FV, low RAW)

Third, support systems that are unique to shutdown configurations will also be identified and ranked accordingly.

There are several safety functions important to shutdown. These are Over-Pressure Protection, Shutdown Cooling, Spent Fuel Pool Cooling, Inventory COMANCHE PEAK - UNITS 1 AND 2 A-10 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1 Control, Reactivity Control, AC Power, and Containment Integrity. Rather than analyzing each function separately, the systems required for the shutdown accident sequences will be analyzed and ranked with respect to their shutdown configurations. This will provide a comprehensive review of the shutdown systems and their unique configurations.

The risk profile for an outage changes as maintenance activities start and stop and plant states change. Therefore, the importance of components can also change during the outage, depending on the plant configuration as governed by the outage schedule. There can be times when almost any component can become more risk significant depending upon the outage scenario. If the plant is in a configuration of increased risk, and an IST component must operate to respond to an accident, that component will be more risk significant for that time period. If that period of time is extended, then the component on average will be more risk significant.

A major difference between at power and shutdown is that safety systems are in a standby mode at power and active components must start or reposition automatically for success. Since actuation failure is much more likely than failure to continue to operate, a reliability-oriented risk importance measure like Fussell-Vesely is lower for outage than at power. However, since functional importance is similar, the RAW value is likely to be the same and its FV is correspondingly lower. Also, during shutdown, automatic actuations are usually blocked and pumps and valves are actuated by manual operation only. Since the failure probability for human action may at times be more likely than automatic actuation, the contribution of equipment failure is relatively less likely. Therefore, in most cases the ranking of components at power is higher than during shutdown, although the system configuration must still be compared to determine if there are unique differences for the shutdown mode. Based upon the insights discussed above, the approach to risk ranking is as follows:

If a component performs the same function and is in the same initial state as at power, the at power ranking is assumed to bound the outage ranking.

If a component performs a different function or is in a different initial state than at power, then the outage ranking must be evaluated.

The latter evaluation involves cases where a different system is used, i.e., spent fuel pool cooling, or where a different function is performed by a component in a system used at power or during an outage. Additionally the following guidelines are used for risk ranking for shutdown.

Back-end Risk Importance It is equally important to identify those pumps and valves that prevent containment failure or bypass that could result in an unacceptable release. Examples might include the valves that provide the boundary between the reactor coolant system and low-pressure systems located outside containment. Various analyses have shown that large releases, though infrequent and of low probability, tend to dominate offsite consequences. Therefore, those IST components identified by back-end analyses will be ranked according to their importance to large early release frequency only.

Containment isolation failures or containment bypass events can, in some accident scenarios, cause a large, early release. The associated valves represent a substantial fraction of components treated by the IST program. However, their importance varies significantly depending on their initial position, their size, the leak path they are in, etc. These factors will be evaluated with a simple model consistent with the PRA back-end analysis. Risk importance of containment functions will be measured by developing quantItative importance measures for accidents contributing to large, early releases.

The large, early releases are more likely to result from accidents with the following attributes:

A failure in containment exists at the time of the accident, either because the containment fails to isolate or it is bypassed, or

A high-pressure core meltdown occurs with containment heat removal (sprays) unavailable at the time of core melting.

One cause of a large, early release is a steam generator tube rupture, with immediate failure of core cooling, and failure of the main steam system to isolate.

A large but not early release can also occur if the same scenario occurs except that core cooling fails late in the accident rather than immediately. This latter scenario is the most likely source of a large release. However, because adequate time would be available to implement emergency response measures, this source of a large release will not be considered in the importance measure calculation.

Instead, the most important sources of main steam isolation failure are considered potentially important and will be reviewed by the IDP to determine if the associated valves should be categorized as high.

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1 IST Components Not in PRA Review components not explicitly modeled in the PRA to ensure an IST component is, in fact, low risk.

High-Risk PRA Components Not in the IST Program Identify other high risk pumps and valves that are not in the IST program but should be tested commensurate with their risk importance.

Evaluate the PRA modeling assumptions, component failure modes, operator actions, recoveries and any other effects that could substantiate the components risk category as high risk even if they are not in the IST Program.

Determine whether current plant testing is commensurate with the importance of these valves. If not, determine what test, e.g., the IST test, would be the most appropriate.

Other Considerations Perform sensitivity studies, as needed, to evaluate the cumulative impact of changes in the IST Program test strategies on the total Core Damage Frequency (CDF).

3) Integrated Decision Process The purpose of utilizing the Integrated Decision Process (IDP) is to confirm or adjust the initial risk ranking developed from the PRA results, and to provide qualitative assessment based on engineering judgement and experience. This qualitative assessment compensates for limitations of the PRA, including cases where adequate quantitative data is not available.

The IDP utilizes deterministic insights, engineering judgement, experience and regulatory requirements as described above in Section 2. The IDP will review the initial PRA risk ranking, evaluate applicable deterministic information, and determine the final safety significance categories. The IDP considerations will be documented for each individual component to allow for future repeatability and scrutiny of the categorization process.

The scope of the IDP includes both categorization and application. The IDP is to provide deterministic insights that might influence categorization. The IDP will identify components whose performance justifies a higher categorization.

The IDP will determine appropriate changes to testing strategies. The IDP will identify compensatory measures for potentially high components or justify the final COMANCHE PEAK - UNITS 1 AND 2 A-14 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1 categorization. The IDP will also concur on the test interval for components categorized as low.

The end product of the IDP will be components categorized as Low Safety Significant Component (LSSC) or High Safety Significant Component (HSSC).

In making these determinations, the IDP will ensure that key safety principles, namely defense-in-depth and safety margins, are maintained and that the changes in risk for both CDF and LERF are acceptable per the guidelines discussed in Section 2 above. The key safety principles are described below.

Defense in Depth To ensure that defense-in-depth is maintained by the CPNPP RI-IST program, adherence to four basic principles will be reviewed and documented as part of the IDP for any future changes to the program. The following describes these four basic principles:

1. No changes to the plant design or operations procedures will be made as part of the RI-IST program which either significantly reduce defense-in-depth or place strong reliance on any particular plant feature, human action, or programmatic activity.

2. The results and dominant contributors to core damage risk will be reviewed to ensure that the categorization of components using PRA is done on an evenhanded basis covering the full scope of safety functions. A review will be done to ensure that components which mitigate the spectrum of accidents are not ranked low solely because of initiating event frequency. Further, sensitivity studies will be performed for human actions to ensure that components which mitigate the spectrum of accidents are not ranked low solely because of the reliability of a human action.

3. The methodology for component categorization, namely the selection of importance measures and how they are applied and understanding the basic reasons why components are categorized HSSC or LSSC, will be reviewed to ensure that redundancy and diversity are preserved as the more important principles. If a component is categorized as LSSC solely due to its high reliability, then it must be confirmed that: 1) plant performance has been good and 2) a compensatory measure or feedback mechanism is available to ensure adverse trends in equipment performance can be detected in a timely manner. A review will be done to ensure that relaxation in the RI-IST program occurs only when the level of redundancy or diversity in the plant design or operation supports it. In this regard, all components that have significant contributions to common cause failure will be reviewed to avoid relaxation of requirements on those components with the lowest level of diversity within the system.

COMANCHE PEAK - UNITS 1 AND 2 A-15 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1

4. The use of multiple risk metrics, including core damage frequency (CDF) and large early release frequency (LERF), with additional checks for large but late releases and consequence mitigation, will be done to ensure a reasonable balance between risk reduction methods.

Other Considerations Related To Defense-In-Depth When the PRA does not explicitly model a component, function or mode of operation, a qualitative method may be used to classify the component HSSC or LSSC and to determine whether a compensatory measure is required.

Sufficient Safety Margin is Maintained The IDP will perform reviews to ensure that sufficient safety margin is maintained when compared to the existing IST program. In performing this review, the IDP will consider such things as proposed changes to test intervals and, where appropriate, test methods.

The IDP will ensure that the proposed compensatory measures are effective fault finding tasks, where this is required in the program, to assure safety margin is maintained. To enhance the safety margin, the IDP will also review PRA-important components not in the current IST program for potential inclusion in the RI-IST program.

Categorization Guidelines Modeled Components/Functions For modeled components/functions with a FV >0.001 the IDP either confirms the component categorization is HSSC or justification of conservatism in the PRA model will be developed.

For modeled components/functions with a FV <0.001, but a RAW >2.0, the component will be categorized LSSC provided a compensatory measure exists that ensures operational readiness and the components performance has been acceptable. If a compensatory measure is not available or the component has a history of performance problems, the component will be ranked HSSC.

For modeled components/functions with a FV <0.001 and a RAW <2.0, the component will be categorized as LSSC provided the components performance has been acceptable. For those components with performance problems, a compensatory measure will be identified to ensure operational readiness or the component will be categorized as HSSC.

Non-Modeled Components/Functions For components not modeled or the safety function not modeled in the PRA, the categorization is as follows:

COMANCHE PEAK - UNITS 1 AND 2 A-16 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1 If the sister train is modeled then the component takes that final categorization.

If the component is implicitly modeled, the FV and RAW are estimated and the deliberation is as discussed for modeled components/functions.

If the component is not implicitly modeled, the system ranking associated with the Maintenance Rule will be confirmed. For confirmed system ranking, the component performance history will be reviewed. For acceptable performance history the component will be categorized as LSSC. For poor performance history, a compensatory measure will be identified to ensure operational readiness and the component categorized as LSSC, or if no compensatory measures are available, categorize the component as HSSC.

Documentation Documentation of the IDP will be available for review at the plant site.

5) Cumulative Impact Evaluate the cumulative impact of the test frequency changes on total plant risk (i.e., CDF and LERF) to ensure that the change in plant safety is within the acceptable range.

This will be done by performing various sensitivity studies to determine the potential risk impact of increasing in-service testing intervals simultaneously on all low risk significant components.

The unavailabilities of the IST components in the low-risk category will be increased by a factor equivalent to the proposed increase in the component test interval. For each sensitivity case, the PRA cutset results will be requantified using the adjusted component unavailabilities due to the proposed test intervals. The new total CDF and LERF for each case will be obtained. These new values will, then, be compared with the CDF and LERF of the base case to assess the net change in total plant risk due to proposed IST test frequencies.

In addition, component risk importances will be re-evaluated for the following groups of IST components to identify any components that may move up from low safety significant components to high safety significant components:

Group 1: Low FV, high RAW with credit taken for compensatory measures identified by the IDP (i.e., other surveillance tests on the same piece of equipment).

Group 2: Low FV, low RAW with no credit taken for compensatory measures because this category implies that increases in component unavailabilities are not expected to impact risk significantly.

COMANCHE PEAK - UNITS 1 AND 2 A-21 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1 Due to uncertainty in how test interval changes will actually affect the component unavailabilities, a number of conservative assumptions are made as summarized below:

It is assumed that any increase in test intervals would simultaneously impact the reliability of all IST components in the low safety-significant component (LSSC) category.

Consistent with the PRA techniques, the component unavailability required to change state, is assumed to be:

Q = OD + (T/2)

Q = total component unavailability Where OD = Component unavailability on demand

= Component failure rate per hour T = Interval between tests that verify operability of the component

The component unavailability is assumed to increase by the same factor as the increase in the test interval. For example, a change in the test interval from quarterly to semi-annually is assumed to increase the total component unavailability by a factor of two. This is a very conservative assumption because it assumes that not only the (T/2) term would be increased by a factor of two, but also the failure on demand term (OD) term is assumed to be directly impacted by the change in the test interval.

Decrease in wear out due to less frequent testing is assumed to be negligible although frequent testing has been seen to cause components to be less available due to wearout.

It is conservatively assumed that all IST tests are fully effective in finding the causes of component unavailabilities.

The PRA models will be updated to reflect the changes to the test frequency of modeled components, and the PRA study will be re-evaluated to quantify the aggregate impact of the changes. The cumulative impact of the test frequency changes will be reviewed through the IDP.

COMANCHE PEAK - UNITS 1 AND 2 A-22 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1

6) Implementation Implementation of the RI-IST to LSSC will consist of grouping components and then staggering the testing of the group over the test frequency.

Grouping:

Components will be grouped based on:

- manufacturer

- model

- service condition

- size The population of the group will be dependent on:

- total population available

- maintaining current testing schedule Grouping components in this manner and testing on a staggered basis over the test frequency will reduce the importance of common cause failure modes as components in the same staggering failure mode group are continually being tested. This ensures that the component capability will be maintained over the test interval (i.e., 6 years).

Testing of components within the defined group will be staggered over the test interval, typically 6 years. Testing will be scheduled on regular intervals over the 6 year period to ensure all components in the group are tested at least once during the 6 year test interval and not all components are tested at one time. The staggering allows the trending of components in the group to ensure the test frequency selected is appropriate.

Testing will be scheduled/planned such that there is no more than one cycle between tests of components in a group.

7) Corrective Action When a component on the extended test interval fails to meet established test criteria, corrective actions will be taken in accordance with the CPNPP corrective action program as described below for the RI-IST.

For components not meeting the acceptance criteria, a Smart Form will be generated.

This document initiates the corrective action process. Also, the initiating event for a COMANCHE PEAK - UNITS 1 AND 2 A-23 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES ATTACHMENT TO R/R A-1 Smart Form may be from causes other than an unacceptable IST test. Programs exist that provide timely information to the IST Engineer that the performance of a reliable component has degraded. For example, a common compensatory action for pump discharge check valves would be the IST pump test. Since this test can not be considered satisfactory if the check valve fails to perform its risk significant function, a test failure would be recorded and a Smart Form initiated. The recorded information could then be used to assess whether a significant change in component reliability has occurred such that the component would merit a change in test interval.

The initiating event could be any other indication that the component is in a non-conforming condition. The unsatisfactory condition will be evaluated to:

a) Determine the impact on system operability and take appropriate action.

b) Review the previous test data for the component and all components in the group.

c) Perform a root cause analysis.

d) Determine if this is a generic failure. If it is a generic failure whose implications affect a group of components, initiate corrective action for all components in the affected group.

e) Initiate corrective action for failed IST components.

f) Evaluate the adequacy of the test strategy. If a change is required, review the IST test schedule and change as appropriate.

The results of component testing will be provided to the PRA group for input to PRA model evaluation. (See Section 8)

For an emergent plant modification, any new IST component added will initially be included at the current Code of Record test frequency. Only after evaluation of the component through the RI-IST Program (i.e., PRA model evaluation if applicable and IDP review) will this be considered LSSC.

8) Periodic Reassessment As a living process, components will be reassessed at a frequency not to exceed every other refueling outage (based on Unit 1 refueling outages) to reflect changes in plant configuration, component performance test results, industry experience, and other inputs to the process. The RI-IST reassessment will be completed within 9 months of completion of the outage.

Part of this periodic reassessment will be a feedback loop of information to the PRA. This will include information such as components tested since last reassessment, number and COMANCHE PEAK - UNITS 1 AND 2 A-24 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES type of tests, number of failures, corrective actions taken including generic implication and changed test frequencies. Once the PRA has been reassessed, the information will be brought back to the IDP for deliberation and confirmation of the existing lists of HSSCs and LCCSs or modification of these lists based on the new data. As part of the IDP, confirmatory measures previously utilized to categorize components as LSSC will be validated. Additionally, the maximum test interval will be verified or modified as dictated by the IDP.

9) Changes to RI-IST after Initial NRC Approval Changes to the process described above and to the evaluation of risk impact will require prior NRC approval. Changes to the categorization of components and associated testing strategies using the above process will not require prior NRC approval. As changes to component categorization are made, TU Electric will periodically submit them to the NRC for their information.

2. NUREG-1482, Revision 1, Guidelines for Inservice Testing atNuclear Power Plants BASIS FOR RELIEF The Safeguards Building Sump Pumps are required to detect and mitigate passive failures in the Emergency Core Cooling System (ECCS) and Containment Spray (CT) System post-LOCA and to prevent flooding of the safety-related systems.

There is no recirculation line from the discharge header of the pumps back to the sumps. There are no installed pressure instruments on the pump suction or discharge. Without a recirculation line on each pump discharge, the only method to meet the Group A Test procedure requirement is to set a reference flow of 0 gpm, dead-head the pump, calculate the differential pressure and record vibration. Differential pressure is determined by making elevation corrections to the discharge pressure reading taken from an installed test gage at a vent connection. This vent connection is remotely located in a different COMANCHE PEAK - UNITS 1 AND 2 A-26 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES room on a different floor elevation than the sump pumps. An elevation difference is also measured on the suction side between the sump cover and the sump water surface. This procedure takes a minimum of four test personnel to conduct the test in this manner. This test has proven to be very difficult and operating experience and equipment history show that testing the pump in a dead-head condition can cause equipment reliability concerns.

CPNPP Inservice Testing Program is an approved Risk-Informed Inservice Testing (RI-IST) Program as described in the Safety Evaluation Report (TAC NOS. M94165, M94166, MA1972, and MA1973). The basis of the RI-IST Program is that there could be safety enhancements obtained by focusing resources on High Safety Significant Components (HSSCs). Extensive testing on Low Safety Significant Components (LSSCs) could have an adverse effect on safety. Reduction of testing should reduce component wear, operator burden, system unavailability, cost of testing, and radiation exposure.

Reduced testing could also achieve a more optimum balance between the positive impacts of testing and the negative effects of disturbing equipment from service and entering a less than optimum plant configuration, such as valve misalignments. The CPNPP Safeguards Building Sump Pumps (SBSPs) have a low risk ranking and are tested every six years on a staggered test basis, such that at least two pumps are tested every 18 months.

To meet the operational readiness requirements for these pumps, a test should require that the pump starts on the proper level switch actuation, determine that the pump is capable of delivering a minimum of 50 gpm to the Waste Holdup Tank (WHT), and that velocity-based vibration readings are satisfactory. Differential pressure measurement is not needed to show adequate pump performance. Differential pressure measurement may result in additional radiation exposure to personnel (ALARA) and potential equipment damage due to dead-heading the pump. Pumping 50 gpm or more to the WHT demonstrates that an adequate head was developed to overcome system resistance and greater confidence exists that the ASME OM Code requirements for operational readiness have been met.

These pumps alert the operator of potential leakage in the safeguards building and mitigate the consequences of the leakage. To meet the testing requirements of ASME OM Code, Subsection ISTB, the pumps must be dead-headed for extended periods.

SUBSTITUTE TEST The pumps shall be tested in accordance with ISTB-5221 (Group A pump test) and ISTB-5223 (Comprehensive pump test) for measuring flow and vibration. The sump will be filled to a predetermined level and the pump will operate until the rapidly (approximately 50 seconds) by COMANCHE PEAK - UNITS 1 AND 2 A-27 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES automatic low-level cutoff switch actuates. The sump will be pumped down rapidly (approximately 50 seconds). Suction pressure will vary as sump level changes; therefore, the 2 minute stabilization time and differential pressure measurement are not achievable. The test will require pumping the same quantity of fluid along a repeatable system path while measuring flow and vibration. A baseline reference value shall be established for flow and vibration. Alert and Required Action Limits for vibration will be established and maintained as per Table ISTB-5221-1 for vertical line shaft centrifugal pumps. Vibration will be measured in a single direction due to the short pump run and the ability to acquire a single vibration reading during this time period. The acceptance criteria for flow will be greater than the design flow of 50 gpm. The flowrate delivered will be trended for detecting pump degradation to ensure the SBSPs have adequate design margin.

V-1, Revision 0 SYSTEM See attached table VALVE NUMBER See attached table CATEGORY See attached table CLASS See attached table DESCRIPTION See attached table BASIS FOR RELIEF Pursuant to the guidelines provided in NUREG-1482, Rev. 1, Section 4.2.5, and the conditions stated in RG 1.192, CPNPP proposes to implement Code Case OMN-1 Revision 1, in lieu of the stroke-time provisions specified in ISTC-5120 for MOVs as well as the position verification testing in ISTC-3700.

TEST REQUIREMENT ISTC-5120, Motor-Operated Valves, ISTC-5121(a) states: Active valves shall have their stroke times measured when exercised in accordance with ISTC-3500.

ISTC-3700, Position Verification Testing, states in part: Valves with remote position indicators shall be observed locally at least once every 2 years to verify that valve operation is accurately indicated.

ISTC-3510, Exercising Test Frequency, states: Active Category A, Category B, and Category C check valves shall be exercised nominally every 3 months, except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3560, ISTC-5221, and ISTC-5222. Power-operated relief valves shall be exercise tested once per fuel cycle.

SUBSTITUTE TEST The use of Code Case OMN-1 Revision 1 by CPNPP permits it to replace stroke time and position verification testing of MOVs with a program of exercising MOVs every refueling cycle and diagnostically testing on longer intervals.

This alternative is considered to be acceptable because Code Case OMN-1 Revision 1 provides a superior method than the stroke-timing method required by the OM code for assessing the operational readiness of MOVs.

Using the alternative to the MOV stroke time testing requirements of ISTC-5120 and position indication verification of ISTC-3700 provide an acceptable level of quality for determination of valve operational readiness. Code Case OMN-1 Revision 1 should be considered COMANCHE PEAK - UNITS 1 AND 2 A-29 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES acceptable for use with ASME OM Code 2004 Edition through 2006 Addenda as the Code of Record.

1) The potential benefits (such as identification of decreased thrustoutput and increase thrust requirements) and potential adverseeffects (such as accelerated aging or valve damage) will beconsidered when determining the appropriate testing for each MOV.

2) Where the selected inservice test frequency extends beyond6 years or 4 refueling outages (whichever is longer),performance and test experience obtained from valve testingconducted during the first 6 year or 4 refueling outage timeperiod shall be evaluated to justify the longer periodicverification frequency.

3) The risk insights determined during TU Electrics participationin the Electric Power Research Institute (EPRI) Risk-InformedInservice Testing Pilot Project (ref. EPRI TR-105869) and on- going development of an updated risk-informed categorizationprocess based upon ASME Research guidance and Codes asapplicable will be used in accordance with the requirements ofthe ASME OM Code Case OMN-1.

Inservice testing shall be conducted in the as-found condition only.

As-found referring to: no maintenance activities that may affect the performance of an MOV shall be conducted prior to performing inservice testing. MOV Preventative Maintenance (PM) activities (including stem lubrication) will be performed on time based intervals to ensure the MOV is maintained in optimum working condition. PM activities will be scheduled separately and frequencies determined independently from MOV inservice test requirements. Performance of a MOV PM will not alter an MOVs as-found status with regards to performing inservice testing. The effects of PM activities on MOV operational readiness will be assessed to ensure the PM activities do not affect the validity of the MOV inservice test results.

Inservice testing shall be sufficient to assess changes in MOV functional margin. Therefore, MOVs requiring maintenance prior to their scheduled inservice test frequency shall be evaluated to determine whether or not performance of an inservice test prior to the maintenance activity will provide sufficient and/or valuable information in assessing changes in the MOVs functional margin. This evaluation, as a minimum, shall consider: inservice test frequency, time from last inservice or preservice test, functional margin, maintenance activity to be performed, grouping, MOV history, risk significance, and a review of the last inservice or preservice test performed. In addition, this COMANCHE PEAK - UNITS 1 AND 2 A-30 Rev. 0

CPNPP UNIT 1 & 2 RISK INFORMED - INSERVICE TESTING PLAN APPENDIX A RELIEF REQUESTS FOR PUMPS AND VALVES evaluation shall be documented for future reference.

Any OMN-1 Code Case requirements that are not currently included in the CPNPP MOV program will be implemented using a controlled process in accordance with OMN-1 and evaluated under 10 CFR 50.59.

CPNPP intends to Maintain the following exceptions to the requirements in ASME Code Case OMN-1 as described below:

1) Paragraph 3.3.1, items (a) & (b) The initial inservice testfrequency for each MOV shall be determined based upon theMOVs risk significance category (i.e. High or Low) andmagnitude of margin. See Figure 1 for initial inservice testfrequency details. The inservice test frequency may changewhen sufficient test data has been collected and analyzed todetermine a more appropriate test frequency. No testfrequency shall exceed 10 years.

2) Paragraph 6.4.3 - In order to maintain consistency andcompatibility with the Joint Owners Group (JOG) MOV PeriodicVerification Program, Functional Margin will be redefined toagree with the definition of Margin as detailed in TopicalReport MPR-1807 (Reference 1). The terms FunctionalMargin and Margin shall be synonymous within the CPNPPMOV Periodic verification program.

Margin, as defined in Reference 1, is dependent uponRequired Thrust. At CPNPP Required Thrust for rising stemMOVs has been determined from stem thrust measurementstaken during extensive baseline testing performed in responseto GL 89-10 under both static and dynamic test conditions.Valve factors have been determined by statistical means foreach group of rising stem MOVs; these factors will bereviewed/verified as new data is obtained from CPNPP testingand results are received from the JOG Periodic VerificationProgram.

Description:

Table 5, "Containment Spray",

Add "(3)" under Leak Test for CT-0142/0145 in Group 28 on Page 1 of 4.

Add Note 3 to Page 4: "3. This valve has a water filled loop seal and is not required to be leakrate tested (see DBD-ME-013, rev. 22, Attachment 1, Note 3)."

Justification: Valves CT-0142/0145 have water seals and are exempt from Appendix J leak testing.

Per DBD-ME-013,Attachment 1, Note 3, "These valves are part of closed systems outside containment tested per NUREG-0737 Section III.D.1 which are in service post-accident and have a water filled loop seal on the containment side of the valves. These valves are either open or closed providing a third barrier to containment leakage. A water seal is maintained both inside and outside containment. These valves are therefore not required to be leakrate tested.

Description:

CPNPP/IST DOC-3 Revision 1

INSERVICE TESTING PLAN FOR PUMPS & VALVES - Description of Changes LDCR-IT-2012-001 (EV-CR-2010-004331-60) (JCH) (continued):

Justification:

The new 3-inch motor operated valve is classified as Nuclear Safety Class 2. The control switch will be used to isolate and bypass 1-HCV-0182 during maintenance and in case of a fire to ensure that the normal charging path is isolated. Replacement of this manual operated valve with a motor operated gate valve will maintain all design and operational functions of the existing valve. This includes the requirement that the valve is a "PASSIVE" open valve. Since the function to close during a fire is important to safety, 1-HV-8402A will be exercise open and closed and position indicated tested.

LDCR-IT-2013-002 (EV-CR-2012-003165-4) (JCH):

Description:

Change the function from "P" to "A" for the following valves in Table 18, Group 91:

DO-011, DO-0187, DO-0211, DO-0287 Justification: These valves are required to protect diesel fuel oil transfer pumps when backpressure from the "Y" strainers requires it. Since this could happen during the Emergency Diesel Generator mission time (30 Days) and no credit had been taken for online maintenance or operator action to protect the pumps, these valves must be classifed as ACTIVE to perform their function as described in the FSAR.

THIRD INTERVAL REVISION 1:

LDCR-IT-2013-005 (EV-CR-2011-009418-17) (JCH):

Table 19 - Motor Operated Valves VALVE TABLE INDEX (VTI)

Description:

Diagnostic Testing column under Test Parameters/Schedule.

The Valve Table Index defines diagnostic testing as follows:

DT-Diagnostic testing determines the cause or mechanism associated with failure, degradation, or performance anomaly of a motor operated valve per the requirements of OMN-1 Rev. 1 (Relief Request V-1)

Justification: Code Case OMN-1 allows users to replace MOV stroke-time testing with a combination of MOV exercising at least every refueling outage and MON diagnostic testing on a longer interval. Table 19 is being enhanced to include an additional column which will identify those MOVs which are required to be "diagnostic" tested.
