Pilgrim Nuclear Power Station Docket No. 50-293 License No. DPR-35 Pilgrim Nuclear Power Station Fourth Ten-Year Inserveice Testing (IST)
Program and Request for Approval of IST Relief Requests LETTER NUMBER:
2.02.109
Dear Sir or Madam:
Entergy Nuclear Operations, Inc. (Entergy) has revised the Pilgrim Nuclear Power Station (PNPS) Inservice Testing (IST) Program as required by 1 OCFR50.55a(f)(4)(ii) for the fourth 10-year interval starting December 7, 2002.
This submittal dockets Pilgrim IST program, Procedure No. 8.1.1.1. and requests NRC approval of IST relief requests, as described in this letter.
The revised IST Program complies with 1995 Edition through 1996 Addenda of the OM Code for Operation and Maintenance of Nuclear Power Plants, Section IST requirements with a few exceptions. These exceptions invoke 10CFR50.55a(f)(4)(iv), the use of portions of later approved ASME OM Code editions and 10CFR50.55a(f)(5)(iii) the notification that conformance with certain code requirements are impractical.
The NRC has recently approved 1998 Edition through 2000 Addenda of the OM Code for Operation and Maintenance of Nuclear Power Plants, (OMb Code - 2000). The following portions of the OMb Code - 2000 will be adopted into the revised IST Program (There are no other related requirements within the OMb Code - 2000 for these paragraphs):
Appendix 1-1390, Test Frequency, Class 2 and Class 3 Pressure Relief Devices that are Used for Thermal Relief Application.
Appendix 1-4110(h) and Appendix 1-4130(g), Pressure Relief Devices - a minimum of 5-minute time elapse between successive openings.
"* Deletion ISTA 2.1, Inspection - Duties of Inspector, Inspector Qualifications, and Access for Inspector.
A summary table of the IST Program Relief Requests requested for approval is enclosed (Attachment 1). This summary table provides a brief description of the impracticality or hardship requiring relief. The updated program Valve Relief Request No. 1 (VR-01) and No. 2 (VR-02) were recently reviewed and granted for ten years in a NRC Safety Evaluation Report (SER) dated September 17, 2002 and May 2, 2001, respectively.

Entergy Nuclear Operations, Inc.
Letter Number: 2.02.109 Pilgrim Nuclear Power Station Page 2 The details of the relief requests are specified in the IST Program Section 7.0 (Attachment 2) as pump and valve relief requests. A relief is requested where PNPS determined a non-conformance to certain Code requirement(s). The relief request provides either an alternative of acceptable level of quality and safety, an alternative since a hardship exists without a compensating increase in the level of quality and safety, or an alternative because it is an impractical requirement for the facility to meet.
PNPS has developed the following schedule plan for implementation of the updated program surveillance requirements:
Subsection ISTB, Inservice Testing of Pumps, will be implemented three months from December 7, 2002, with the exception of Reactor Building Closed Cooling Water (RBCCW) and High Pressure Coolant Injection (HPCI) pump testing, which will be implemented upon receipt of NRC approval of the pump relief requests. Until then Pilgrim will continue to comply with the third 10-year IST Interval program requirements for RBCCW and HPCI pumps.
Implementation of Subsection ISTC, Inservice Testing of Valves, will begin three months from December 7, 2002.
Entergy requests timely NRC review and approval of IST Relief Requests in order to support implementation of the new program.
If you have any questions or require additional information, please contact Mr. Bryan Ford, Licensing Manager, at (508) 830-8403.
Sincerely, NKJ.

REVISION LOG REVISION 15 Date Originated 5/02 Pages affected Description All The Inservice Pump and Valve Testing Program is being upgraded in accordance with 10CFR50.55a(f)(4)(ii) which requires compliance with the latest approved Code incorporated within 1 OCFR50.55a(b). The Code of record and that which is adopted for this upgrade is ASME OM, Code For Operation And Maintenance of Nuclear Power Plants, 1995 Edition through 1996 Addenda.
In addition to the Code upgrade, this program revision clarifies 10CFR50.55a(f)(1) such that the component scope includes those pumps and valves which are part of the Reactor coolant boundary, thus meeting the applicable requirements of ASME Code Class 1.
Also included are other pumps and valves that perform a function to shut down the Reactor or maintain the Reactor in a safe shutdown condition, mitigate the consequences of an accident, or provide overpressure protection for safety-related systems and must meet the test requirements applicable to components which are classified as ASME Code Class 2 or Class 3. This distinction is of importance since numerous components not being assigned as ASME Code C:ass 1, 2, or 3 will no longer be tested as part of the IST Program. These safety-related components not being cesianated ASME Class 1, 2, or 3 will become part of the new Appendix B Pump and Valve Testing (ABT) Program.
A new program is being established for check valve condition monitoring The Condition Monitoring Program is an alternative to the testing or examination requirements of Paragraphs ISTC 4.5.1 through ISTC 4.5.4.
Finally, this upgrade requires major modification in Code Justifications and the creation of new Code Relief Requests. A Code Justification explains how compliance to Code allowed deviations are satisfied and does not require Commission approval.
The new justifications take the format of cold shutdown (CS),
Refueling Outage (RJ), Disassembly (DJ), and Series Pair (SJ) for valve and pressure relief devices. The new Code Relief Requests are to identify noncompliance with OMa Code requirements and must receive Commission approval prior to implementation.
The entire document was revised; therefore, no revision bars are shown.

1.0 PURPOSE AND SCOPE This Procedure encompasses and controls the PNPS Inservice Testing (IST) Program. It identifies the scope of components (pumps and valves) and testing requirements for compliance with 10CFR50.55a(f), Inservice Testing Requirements. This Procedure will be utilized for the IST Program submittal to satisfy ISTA 2.2.3 Inservice Test Interval and to identify impractical Code requirements in accordance with 10CFR50.55a(f)(5).
Impractical Code requirements are reviewed and dispositioned by the Nuclear Regulatory Commission (NRC) and documented in a Safety Evaluation Report authored by the Office of Nuclear Reactor Regulation as related to the Inservice Testing Program and Requests for Relief The NRC will grant program relief requests pursuant to 10CFR50.55a(a)(3)(i),
10CFR50 55a(a)(3)(ii), or 10CFR50.55a(f)(6)(i). Granting of relief ensures that the IST Program has satisfactorily demonstrated that either: 1) the proposed alternative provides an acceptable level of quality and safety, 2) compliance would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety, or 3) conformance with certain requirements of the applicable Code edition and addenda is impractical for its facility.
2.0 DISCUSSION The sccce of the IST Program includes those safety-related pumps and valves which are part of the Reactor coolant pressure boundary and must meet the requirements applicable to components classified as ASME Code Class 1. Additionally, other safety-related pumps and valves that perform a function to shut down the Reactor or maintain the Reactor in a safe shutdown condition, mitigate the consequences of an accident, or provide overpressure protection for safety-related systems meet the test requirements applicable to components which are classified as ASME Code Class 2 or Class 3. This scope is limited to those pumps and valves identified as meeting ASME Code Class 1, 2, or 3 in accordance with Regulatory Guide 1.26 classifications. The pumps and valves not performing a function as stated above or those meeting the exclusion requirements of the OMa Code need not be tested, but the bases for a component's exclusion must be justified. TDBD-121, "Topical Design Basis Document for In-Service Testing (IST)", provides the bases information related to IST Program exclusions.
Non-ASME Code Class safety-related pumps and valves that perform a function to shut down the Reactor or maintain the Reactor in a safe shutdown condition, mitigate the consequences of an accident, or provide overpressure protection for safety-related systems are to be tested under the requirements of 10CFR50 Appendix B. The scope of the PNPS Appendix B Test Program includes those safety-related pumps and valves identified as non-ASME Code Class in accordance with Regulatory Guide 1.26 but would be considered ASME Code Class 1, 2, 3.
8.1.1.1 Rev. 15 Page 5 of 179
This Procedure details the following items: compliance requirements, general information, pump hydraulic circuits, and tables of the components (pumps and valves) tested. The last Section (7.0) contains Valve Justifications (i.e., cold shutdown, Refuel Outage, Disassembly Examination, and Series Valve Pairs) and Relief Requests. In addition, the Procedure references the Condition Monitoring Program for check valves.
The Procedure's pump and valve tables provide a cross-reference between a component test requirement and a Station Procedure implementing the test. Additional information is provided within this component listing: safety class, category, test frequency, test parameters, Relief Requests, justifications, and remarks. Newly incorporated component/test requirements will have implementing Procedures identified for future incorporation. All newly identified component/test requirements shall be initially tested during the next scheduled frequency (i.e.,
quarterly, cold shutdown, refueling interval, and 2 years) following Procedure approval date.
These newly incorporated component/test requirements will be identified by an asterisk (*) next to the implementing Procedure. When using (*) Procedures for postmaintenance testing, the current approved Procedure should be reviewed for applicability (i e, is the new test requirement or component incorporated)
PNPS 8.1.1, "Administration of Inservice Pump and Valve Testing", covers the administrative requirements for the development, performance, and maintenance of the PNPS Inservice Test Program in accordance with the ASME OMa Code for Operation and Maintenance of Nuclear Power Plants, and includes the 1995 Edition through 1996 Addenda.
Station ALARA practices have been considered when addressing ASME Code test requirements within this Procedure. When test requirements are added or revised, good ALARA practices should be incorporated to minimize personnel dose.

4.0 COMPLIANCE This Inservice Pump and Valve Testing Program will be in effect through the fourth 120-month test interval (ending December 7, 2012) and will be updated in accordance with the requirements of ISTA 2.2.3(c)(2) and 10CFR50 55a(f)(4)(ii).
This Procedure outlines the PNPS IST Program based on the requirements of the ASME OM Code for Operation and Maintenance of Nuclear Power Plants, 1995 Edition through the 1996 Addenda subject to the following limitations and modifications specified in IOCFR50.55a(b)(3):
[1]
Appendix II The following modifications apply when implementing Appendix II, "Check Valve Condition Monitoring Program," of the OM Code, 1995 Edition with the 1996 Addenda."
(a)
"Valve opening and closing functions must be demonstrated when flow testing or examination methods (nonintrusive, or disassembly and inspection) are used;"
(b)
"The initial interval for tests and associated examinations may not exceed two fuel cycles or 3 years, whichever is longer; any extension of this interval may not exceed one fuel cycle per extension with the maximum interval not to exceed 10 years; trending and evaluation of existing data must be to reduce or extend the time interval between tests."
(c)
"If the Appendix II condition monitoring program is discontinued, then the requirements of ISTC 4.5.1 through 4 5 4 must be implemented."
The Inservice Testing Program is invoking 10CFR50.55a(f)(iv), the use of portions of later approved ASME Code editions The recent approval of the 1998 Edition through 2000 Addenda of the OM Code, Section IST into the federal regulations allows for use of the following:
Appendix 1-1390, Test Frequency, Class 2 and Class 3 Pressure Relief Devices That Are Used For Thermal Relief Application 8.1.1.1 Rev. 15 Page 8 of 179
Appendix 1-4100(h) and Appendix 1-4130(g), Allow Pressure Relief Devices a Minimum of 5 Minute Elapse Time Between Successive Openings Deletion of ISTA 2.1, Inspections that Include Duties of Inspectors, Inspector Qualification, and Access for Inspector 10CFR50.55a(f)(1) provides guidance for inclusion of ASME Code 1, 2, and 3 components into the IST Program. The guideline states that "pumps and valves which are part of the Reactor coolant pressure boundary must meet the requirements applicable to components which are classified as ASME Code Class 1. Other safety related pumps and valves [that perform a function to shut down the Reactor or maintain the Reactor in a safe shutdown condition, mitigate the consequences of an accident, or provide overpressure protection for safety-related systems - in or when meeting the requirements of the OM Code, or later] must meet the test requirements applicable to components which are classified as ASME Code Class 2 or Class 3". ASME safety related components that apply to IST are those pumps and valves included within the scope of Regulatory Guide 1.26.
The IST Program has incorporated a Condition Monitoring Program which establishes as an alternative to the test or examination requirements (ISTC 4.5 1 through ISTC 4 5 4) for a check valve or check valve group If this Procedure conflicts with PNPS Tecnnical Specifications, a Technical Specifications amendment shall be suomitted to conform the Technical Specifications to this Procedure in 3ccordance with 10CFR50.55a(f)(5)ii') Until approval c-theTe- "nical Specifications amendment, the most limiting recuujr_--ent shall be met.

5.0 INSERVICE PUMP TESTING 5.1 GENERAL INFORMATION
[1]
Applicable Code This Inservice Testing Program addresses those ASME Code Class 1, 2, and 3 centrifugal and positive displacement pumps that meet the requirements of Subsection ISTB of ASME OMa Code 1995 Edition through Addenda 1996 The applicability of the subsection establishes the requirements for preservice and inservice testing to assess the pump's operational readiness. The pumps covered are those provided with an emergency power source and that are required in shutting down a Reactor to the safe shutdown condition, maintaining the safe shutdown condition, or mitigating the consequences of an accident The following pump exclusions exist:
drivers (except where the pump and driver form an integral unit and the pump bearings are in the driver), pumps that are supplied with emergency power solely for operating convenience and skid-mounted pumps that are tested as part of the major component.
The skid-mounted pumps are excluded when they have been determined by the owner to be adequately tested (
Reference:
TDBD-121, Topical Design Basis Document for In-Service Testing).
Where the above requirements for ASME Class 1, 2, or 3 pumps are determined to be impractical, requests for relief have been written and are included in Section 7 0 as follows.
(a)
RELIEF REQUEST (PR-XX) - Relief Requests are included in Section 7 1 and identify those impractical test requirements. A Relief Request must be reviewed and approved by the NRC prior to use.
[2]
Pump Program Table Description The table in Section 5.3 lists all pumps included in the Pilgrim Nuclear Power Station (PNPS) IST Program. This program defines pumps as mechanical devices used to move liquid. The program addresses centrifugal and positive displacement pumps according to ISTB 1.1, Applicability. Skid-mounted pumps have been identified for information but excluded from inservice testing. The column headings of the table are listed and explained below:
(a)
SYSTEM: System Title (b)
PUMP No: Pump Identification Number (c)
IST CLASS: IST Classification (Class 1, 2, or 3)
(d)
P&ID/COORD.: PNPS drawing number and coordinate location (e)
PUMP TYPE A or B: Pump type as specified in OMa-1996 Section ISTB 8.1.1.1 Rev 15 Page 10 of 179
(f)
TEST A OR B (FREQ.) AND COMPREHENSIVE PROC. (FREQ). The PNPS test Procedure number and frequency of inservice tests as prescribed in ISTB Table 5 1-1, Inservice Test Frequency (g)
TEST QUANTITIES (SPEED, PRESS, FLOW, AND VIB): Inservice test quantities to be measured following the guidelines of ISTB Table 4.1-1, Inservice Test Parameters
[3]
"Inservice Test Quantities" PUMP SPEED (N), DISCHARGE PRESSURE (Pd) or DIFFERENTIAL PRESSURE (DP), FLOW RATE (0), VIBRATION (V): When the symbol "Y" appears in a particular measured parameter column, that quantity will be measured during inservice testing in accordance with Subsection ISTB.
[4]
Measurement of Inservice Test Quantities (a)
Speed (N): In accordance with Table ISTB 4.1-1, Inservice Test Parameters, shaft measurements are not applicable (NA) for pumps coupled to synchronous or induction type drivers, but only if variable speed For variable speed pumps, the pump speed shall be set at the reference speed in accordance with ISTB k7 1 and 4 7 3.
(b)
Discharae Pressure (Pd)- For positive displacement pumps, discharge pressure will be measured in lieu of differential pressure in accordance with Tanle ISTB 4.1-1 (all other pumps will have discharge pressure measured if it is needed to determine differential pressure)
(c)
Differential Pressure (DP) Differential pressure measurements will be calculated from inlet and discharge pressure measurements or by direct differential pressure measurement The differential pressure will be measured for centrifugal pumps, including vertical line shaft pumps, in accordance with Table ISTB 4.1-1. The Service Water Pumps are an exception because the individual SSW pump suction is not configured to obtain pump suction pressure.
This parameter is determined by analytical method using suction bay level instruments and is then converted to the equivalent suction pressure The analytical method has been determined to meet the required instrument accuracy
(+/- 1/2%) of Table ISTB 4 7.1-1 in accordance with ISTB 4.7.1(a).
(d)
Vibration (V): Pump vibration will be measured on centrifugal, vertical line shaft, and reciprocating pumps. On centrifugal pumps, measurements shall be taken in a plane approximately perpendicular to the rotating shaft in two orthogonal directions on each accessible pump-bearing housing and on the axial direction on each accessible pump thrust bearing housing. On vertical line shaft pumps, measurements shall be taken on the upper motor-bearing housing in three approximately orthogonal directions, one being the axial direction. On reciprocating pumps, measurements shall be taken on the bearing housing of the crankshaft, approximately perpendicular to both the crankshaft and the line of plunger travel.
8.1 1.1 Rev. 15 Page 11 of 179
[5]
Allowable Ranges of Test Quantities The allowable ranges specified in Table ISTB 5.2.1-1 and Figure ISTB 5.2-1 will be used for vibration measurements for Group A and Comprehensive Tests. The allowable ranges specified in Table ISTB 5.2 1-2, Table ISTB 5 2 2.-1, and Table ISTB 5.2.3-1 will be used for discharge pressure, differential pressure, and flow measurements for Group A, Group B, and Comprehensive Tests, respectively.
[6]
Corrective Action The operational readiness of a pump shall be determined by comparing Surveillance Procedure test results to the established Acceptable, Alert, and Required Action Ranges.
(a)
If deviations fall within the Alert Range of Table ISTB 5.2.1-1, Table ISTB 5.2.1-2, Figure ISTB 5 2-1, or Table ISTB 5.2 3-1, as applicable, the frequency of testing shall be doubled until the cause of the deviation is determined and the condition corrected.
(b)
If deviations fall within the Required Action Range of Table ISTB 5.2.1-1, Table ISTB 5.2.1-2, Figure ISTB 5.2-1, or Table ISTB 5 2.3-1, as applicable, the pump shall immediately be declared inoperative and not returned to service until the cause of the deviation has been determined and the condition corrected, or an evaluation is performed and new reference values are established.
(c)
When a test shows a systematic error,mo rcoer system lineup or inaccurate instrumentation) such that a measured ca-- ieter value(s) falls outside the Acceptable Range, the test shall be rerun after correcting the error.
[7]
Instrument Accuracy Instrument accuracy is defined as the allowable inaccuracy of an instrument loop (i.e.,
two or more instruments or components working together to provide a single output) based on the square root of the sum of the square of the inaccuracies of each instrument or component in the loop when considered separately. Alternatively, the allowable inaccuracy of the instrument loop may be based on the output for a known input into the instrument loop Allowable instrument accuracies are provided in Table ISTB 4.7.1-1. If the accuracies of plant-installed instrumentation are not acceptable, temporary M&TE instruments meeting the acceptable accuracies will be used. For individual analog instruments, the required accuracy is a percent of full scale. For digital instruments, the required accuracy is over the calibrated range. For a combination of instruments, the required accuracy is loop accuracy.
Guidance provided within NUREG-1482 and the summary of public workshops held in NRC regions on Inspection Procedure 73756 will be used for meeting the OM Code instrument accuracy requirements.
In cases where a parameter is determined by analytical methods instead of being measured, the requirements of ISTB 4 7.1 must be adhered to.
8.1.1.1 Rev. 15 Page 12 of 179
[8]
Excluded Safety Related Pumps The Reactor recirculation pumps and the recirculation jet pumps are examples of pumps excluded from inservice testing Excluded pumps do not meet the applicability requirements of Subsection ISTB in that they are not required to perform a specific function in shutting down the Reactor to the safe shutdown condition, maintaining the safe shutdown condition, or mitigating the consequences of an accident. Additionally, all pumps that meet the exclusion requirements of ISTB 1.2 will be identified within the bases document (TDBD-121).
[9]
Skid-Mount Pumps Skid-mounted pumps are defined as pumps that are integral to or that support operation of the major component, even though these pumps may not be located directly on the skid. Generally, the manufacturer of the major component supplies these pumps.
Examples of systems having skids as a subassembly include High Pressure Coolant Injection System and Reactor Core Isolation Cooling System ASME Code Class 1, 2, and 3 skid-mounted pumps that are tested as part of the major component are listed in both the IST Program and bases document. The IST basis documentation contains the specific details necessary to ensure pumps classified as skid-mounted are adequately tested.
[10]
Test Regulrermrnts Preservice and inservice test periods are used to establish the proper test method in the establishment of an initial set of reference values for a new pump The preservice test period is the time interval prior to or before implementing inservice testing (i e., the start of the pump's service life) The inservice testing shall commence when the pump is required to be operable and continue until the pump is retired (i.e., removed from service).
[11]
Test Group The IST Program centrifugal and positive displacement pumps are to be grouped by their inservice run time. Grouped as Type A or Type B, this allows for the development of unique test requirements due to the service the pump experiences as follows:
(a)
Group A pumps are those operated continuously or routinely during normal operation, cold shutdown, or refueling operations.
(b)
Group B pumps are those in standby systems that are not operated routinely except for testing.
8.1.1.1 Rev. 15 Page 13 of 179
[12]
Test Methods (a)

6.0 INSERVICE VALVE TESTING 6.1 GENERAL INFORMATION
[1]
Applicable Code This Inservice Testing Program addresses those valves and pressure relief devices (and their actuating and position indicating systems) that meet the requirements of Subsection ISTC of ASME OMa Code 1995 Edition through Addenda 1996. The applicability of the subsection establishes the requirements for preservice and inservice testing to assess the valve's or pressure relief device's operational readiness. Both active and passive valves are covered by this Procedure and include those that are required in shutting down the Reactor to the safe shutdown condition, maintaining the safe shutdown condition, or mitigating the consequences of an accident. The pressure relief devices covered are those for protecting systems or portions of systems that are required in shutting down the Reactor to the safe shutdown condition, maintaining the safe shutdown condition, or mitigating the consequences of an accident. The following exclusions exist valves used only for operating convenience (i.e., vent, drain, instrument, and test valves), valves used only for system control (i.e., pressure regulating valves), and valves used only for system or component maintenance.
Skid-mounted valves and component subassemblies that are tested as part of the major component are excluded when determined by the owner to be adequately tested.
Additionally, external control and protection systems responsible for sensing plant conditions and providing signas for valve operation are excluded.
Where the above requirements for ASME Class 1, 2, or 3 valves and pressure relief devices are determined to be impractical, specific justifications and requests for relief have been written and included in Section 7.0 as follows:
(a)
RELIEF REQUEST (VR-XX): Relief Requests are included in Section 7.6 and identify impractical test requirements. These Relief Requests must be reviewed and approved by the NRC prior to use (b)
COLD SHUTDOWN JUSTIFICATION (CS-XX) These justifications are located in Section 7.2 The justification provides the mechanism for documenting the bases for performing a specific test on a cold shutdown (CS) frequency.
(c)
REFUELING OUTAGE JUSTIFICATION (RJ-XX)- These justifications are located in Section 7.3. The justification provides the mechanism for documenting the bases for performing a specific test on a refueling interval (RI) frequency (usually during a refueling outage) as well as specifying the alternative requirements.
8.1.1.1 Rev. 15 Page 21 of 179
(d)
DISASSEMBLY EXAMINATION JUSTIFICATION (DJ-XX): These justifications are located in Section 7 4 The justification provides the mechanism for documenting the bases for establishing a sample disassembly examination program, to verify valve obturator movement, on a refueling interval (RI) frequency.
(e)
SERIES VALVE PAIR JUSTIFICATION (SJ-XX): These justifications are located in Section 7.5. The justification provides the mechanism for documenting the bases for testing valves as a series pair, as well as providing the alternative requirements.
[2]
Inservice Valve Testing Program Table The tables contained in Section 6.2 list all 1ST Class 1, 2, and 3 valves that are tested to meet IST requirements Skid-mounted valves are identified but are excluded from testing.

Excluded Valves Valves excluded according to ISTC 1.2 and passive valves that do not have a specific leakage requirement are not included in the IST Program. A passive valve is a valve that maintains obturator position and is not required to change obturator position to accomplish the required function(s).
Subsection ISTC excluces,,alves provided that they are not required to perform a specific function in shutting down the Reactor to the safe shutdown condition, in maintaining the safe shutdown condition, or in mitigating the consequences of an accident includes:
Valves used only for operating convenience, system control, and maintenance Skid-mounted valves and component subassemblies are excluded provided that they are tested as part of the major component and determined by the owner to be adequately tested.
External control and protection systems responsible for sensing plant conditions and providing signals for valve operation.
Control valves whose actuators are required to provide a fail-safe position have been included in the program in accordance with Generic Letter 89-04 and are fail-safe tested only. Excluded valves with remote position indicators have been included so their position indicators will be checked with the "excluded" status noted.
[4]
Check Valve Condition Monitoring Program (CMP)
PNPS has developed a check valve Condition Monitoring Program in accordance with ISTC 4.5.5. This program is an alternative to the testing requirements of ISTC 4.5.1 through ISTC 4.5 4 Check valves have been placed in the Condition Monitoring Program with the purpose of improving check valve performance and to optimize activities to maintain the continued acceptable performance of the selected valves.
8.1.1.1 Rev. 15 Page 24 of 179
This CMP complies with OM Code Appendix II. This mandatory Appendix contains the requirements to augment the rules of Subsection ISTC. In addition to the mandatory Appendix, the limitations and modifications specified in 10CFR50.55a(b)(3) for implementing the Appendix II, "Check Valve Condition Monitoring Program", of the OM Code 1995 Edition with the 1996 Addenda, are mandated as part of the PNPS Condition Monitoring Program The Valve Program Tables in Section 6.2 of this Procedure assign a test frequency of "CMP" for each valve selected as part of the Condition Monitoring Program. The Valve Program table for CMP valves will continue to specify other Code-related information, such as justifications, notes, safety direction, and test requirements for the selected valves. These items will have no impact on the CMP but will remain for historical informational purposes. IST 4.5 5 requires that if Condition Monitoring is discontinued for a valve or valve group, then the requirements of ISTC 4.5.1 through ISTC 4.5.4 shall apply The following check valves have been placed into the PNPS Condition Monitoring Program CONDITION MONITORING PROGRAM VALVES Valve No.

[5]
Measurement of Test Quantities (a)
Stroke Time: The preferred stroke time method is the time interval from initiation of the actuating signal to the end of the actuating cycle. Alternate stroke timing methods may be utilized and are discussed within PNPS 8.1.1, "Administration of Inservice Pump and Valve Testing". The stroke time acceptance value(s) for each power-operated valve is specified within the appropriate test Procedure.
These times shall be measured at least to the nearest second. Additionally, abnormal or erratic action shall be recorded and evaluated (b)
Position Indication Valve disk movement is determined by exercising the valve while locally observing the appropriate indicators which signal the required change of disk position. Where local observation is not possible, other indications shall be used for verification of valve operation. A suitable method is the use of indirect evidence (such as changes in system pressure, flow rate, level, or temperature) which reflects stem or disk position to verify that remote position indicators agree with valve travel direction (c)
Seat Leakage: Seat leakage is measured by one of the following methods.
(1)
Measuring leakage through a downstream telltale connection while maintaining test pressure on one side of the valve.
(2)
Measuring the feed rate required to maintain test pressure in the test volume or between two seats of a gate valve, provided that the total apparent leakage rate is charged to the valve or valve combination or gate valve seat being tested and the conditions required by ISTC 4.3 3(b) are satisfied.
(3)
Determining leakage by measuring pressure decay in the test volume, provided that the total apparent leakage rate is charged to the valve or valve combination or gate valve seat being tested and the conditions required by ISTC 4 3.3(b) are satisfied.
Exception: Containment isolation valves are seat leak tested in accordance with the 10CFR50 Appendix J program.
8 1.1.1 Rev. 15 Page 26 of 179
(d)
Check Valve Exercise Test: Each OM Code exercise test shall include both exercise open and exercise close tests. Exercise open and exercise close tests need only be performed at an interval when it is practicable to perform both tests.
Test order (e.g., whether the exercise open test precedes the exercise close test) is not important and not required to be performed at the same test frequency as long as they are both performed within the same test interval. Observations shall be made by observing a direct indicator (e.g., a position-indicating device) or by other positive means (e g, changes in system pressure, flow rate, level, temperature, seat leakage, testing, or nonintrusive testing results). The following test practices will be utilized:
(1)
Safety function in both open and close directions - shall be tested by initiating flow and observing that the obturator has traveled to either the full open position or to the position required to perform its intended function(s) and verify that, on cessation or reversal of flow, the obturator has traveled to the seat (2)
Safety function in open direction only - shall be tested by initiating flow and observing that the obturator has traveled to either the full open position or to the position required to perform its intended function(s) and verify closure.
(3)
Safety function in closed direction only - shall be tested by initiating flow and observing that the obturator has traveled to at least the partially open position (i.e., normal or expected system flow position) and verify that, on cessation or reversal of flow, the obturator has traveled to the seat.
(4)
Mechanical Exerciser - the breakaway force or torque delivered to the disk by the exerciser shall not vary by more than 50% from the established reference value. The reference value shall be obtained when the valve is known to be operating properly and taken under conditions as close as practicable to the conditions under which the valve will be tested (e.g., wet versus dry, equivalent static head, etc.).
(5)
Vacuum Breaker - for check valves that perform as vacuum breakers, the exerciser force or torque delivered to the disk may be equivalent to the desired functional pressure differential force. Also, the disk movement shall be sufficient to prove that the disk moves freely off the seat. If no functional pressure differential force is specified, only disk movement is required 8.1.1.1 Rev. 15 Page 27 of 179
(e)
Check Valve Disassembly: For certain check valves in which the safety function (i.e., sufficient flow, full open position or travel to seat) cannot be satisfied by the acceptable test methods, a sample disassembly examination program may be used to verify valve obturator movement. The sample program has the following restrictions:
(1)
Grouping of check valves to be technically justified and consider, as a minimum, manufacturer, design, service, size, materials of construction, and orientation (2)
The full-stroke motion of the obturator shall be verified during disassembly. The full stroke motion of the obturator shall be reverified immediately prior to completing reassembly Additionally, valves that have their obturator disturbed before the full-stroke motion (e g., spring-loaded lift check valves or check valves with the obturator supported from the bonnet) are examined to determine whether a condition exists that could prevent full opening or reclosure of the obturator.
(3)
One check valve of each group is disassembled and examined each refueling outage with all valves in each group being disassembled and examined at least once every 8 years.
(4)
Valves that were disassembled and examined or that received maintenance that could affect their performance shall be exercised if practicable prior to being returned to service.
The check valve disassembly program will be controlled in accordance with PNPS 8.1.27. Currently no check valves are assigned to the disassembly program.
(f)
Nonintrusive Testing Of Check Valves-Nonintrusive testing (NIT) is an acceptable method for verifying valve obturator movement in accordance with ISTC 4.5.4(3). However, if the NIT results are inconclusive for verifying the check valve exercise test, then another acceptable method may be used. If no other methods can be used to perform the exercise test, then the affected valve may be disassembled using the guidelines within PNPS 8 1.27, "lnservice Check Valve Sample Disassembly and Exercise Program" For check valves that are periodically verified through NIT techniques as being exercised, a sample plan may be employed. The sample plan will typically use the alternative requirements specified within ISTC 4.5 5, Condition Monitoring Program. NIT sample testing will be controlled in accordance with PNPS 8.1.37, "Inservice Check Valve Nonintrusive Testing for Exercise Program".
8.1.1.1 Rev. 15 Page 28 of 179
(g)
Excess Flow Check Valve (EFCV) Testinq Relaxation: NEDO-32977-A and the associated NRC Safety Evaluation, dated March 14, 2000, provide the basis for relaxing the EFCV testing frequency The relaxation of the number of EFCVs tested every refueling outage is from "each" to a "representative sample" (nominally once every 24 months). The representative sample is based on (approximately) 20% of the valves tested each 2-year cycle such that each valve is tested every 10 years (nominal). Refer to VR-01 and VR-02 for applicable EFCVs and specific implementation data.
(h)
Relief Valves-Periodic testing of pressure relief valves is required No maintenance, adjustment, disassembly, or other activity which could affect "as found" set-pressure or seat tightness data is permitted prior to testing. The ASME OM Code Interpretation No. 98-8, ASME/ANSI OM-1987, Part 1, Para 3 3.1.1, Main Steam Pressure Relief Valves With Auxiliary Actuating Devices, provides concurrence that PNPS use of a slave main valve body for testing SRV pilot assemblies is acceptable and in compliance with Appendix 1,Section I 3 3 (Periodic Testing) requirements (1)
Class 1 Main Steam Pressure Relief Valves With Auxiliary Actuating Devices are to be tested in the following sequence: visual examination, seat tightness determination, and set-pressure determination. Then the remaining may be performed following maintenance or set-pressure adjustment electrical characteristic and pressure integrity of solenoid valves, pressure integrity and stroke capability of air actuator, electrical characteristics of position indicators, electrical characteristics of bellows alarm switch, actuating pressure of sensing element devices and continuity, and owner's seat tightness criteria, when applicable.
(2)
Class 1 Main Steam Pressure Relief Valves Without Auxiliary Actuating Devices are to be tested in the following sequence: visual examination, seat tightness determination, and set-pressure determination. Then the remaining may be performed following maintenance or set-pressure adjustment: electrical characteristics of position indicators and owner's seat tightness criteria, when applicable.
(3)
Class 2 and 3 Pressure Relief Valves are to be tested in the following sequence-visual examination, seat tightness determination, and set-pressure determination. Then the remaining may be performed following maintenance or set-pressure adjustment* integrity of the balancing device on balanced valves and owner's seat tightness criteria, when applicable.

[6]
Allowable Ranges of Test Quantities (a)
Stroke Time: Stroke time acceptance criteria are categorized as being applicable to either electric motor-operated or power-operated (e.g., air-operated, solenoid-operated, hydraulic-operated, etc.) valves The observed stroke times will not exceed the following Acceptance Criteria:
(1)
Electric motor-operated valves with reference stroke times greater than 10 seconds shall exhibit no more than +/- 15% change in stroke time when compared to the reference value.
(2)
Power-operated valves with reference stroke times greater than 10 seconds shall exhibit no more than +/- 25% change in stroke time when compared to the reference value.
(3)
Electric motor-operated valves with reference stroke times less than or equal to 10 seconds shall exhibit no more than a +/-25% nor_ +/-1 second change in stroke time, whichever is greater, when compared to the reference value (4)
Power-operated valves with reference stroke times less than or equal to 10 seconds shall exhibit no more than +/- 50% change in stroke time when compared to the reference value.
(5)
Valves with stroke times less than 2 seconds may be exempted from the reference value change requirement For these cases, the maximum limiting stroke time will be 2 seconds (b)
Position Indication: During valve opening and closure following maintenance, the remote position indicators shall accurately reflect valve travel direction.
(c)
Seat Leakage.
(1)
Valve leakage rates shall not exceed the value established by PNPS Engineering. These leakage values are specified within the implementing test Procedures. Valves (or valve combinations) that fail to meet the acceptance criteria shall be declared inoperable immediately and require corrective action.
(2)
The Code recommended "permissible" leakage rates for a valve or a valve combination not specified by the owner (PNPS Engineering) are as follows for water 0.5D gal/min or 5 gal/min, whichever is less, at function pressure differential, or for air, at function pressure differential, 7.5D standard ft3/day where D equals nominal valve size, inches. Refer to ISTC 4.3 3(e) for further guidance.
8.1.1.1 Rev. 15 Page 30 of 179
[7]
Instrument Requirements Instruments used to measure stroke times shall be capable of measurement to the nearest tenth of a second.
[8]
Corrective Action (a)
Stroke Time (1)
If a valve fails to exhibit the required change of obturator position or exceeds the limiting value of full-stroke time, it shall be immediately declared inoperable.
(2)
Valves that do not meet the measured stroke time acceptance criteria shall be immediately retested or declared inoperable. If the valve is retested and the second set of data does not meet the acceptance criteria, the data shall be analyzed within 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> to verify that the new stroke time represents acceptable valve operation, or the valve shall be declared inoperable. If the second set of data meets the acceptance criteria, the cause of the initial deviation shall be analyzed and the results documented.
(3)
Valves declared inoperable may be repaired, replaced, or the data may be analyzed to determine the cause of the deviation and the valve shown to be operating acceptably (4)
Before returning a repaired or replacement valve to service, a test shall be performed demonstrating satisfactory operational readiness (5)
A completed Attachment 4 of PNPS 8.1.32, combined with either a Corrective Action/Evaluation Form (Attachment 1 of PNPS 8.1.1) or a Surveillance Review Sheet (reference PNPS 1.3.34 Attachment 9) with ASME Test Engineer signature, satisfies the corrective action evaluation requirements for valve operability If necessary, a valve may be declared operable using the Surveillance Test Review process prior to revision of the affected stroke timing Procedure A revision to the Surveillance Procedure should then be implemented on a priority basis for future operability testing 8.1.1.1 Rev. 15 Page 31 of 179
(b)
Seat Leakaqe: Corrective action shall be to repair or replace the valve or valve combination unless an Engineering analysis is performed which demonstrates that the leakage criteria may be increased and the new leakage rate will not impact the valve's ability to fulfill its safety function. The option to evaluate and increase leakage criteria should not be used for Reactor system pressure isolation valves (PIVs) without performance of an evaluation which includes consideration of applicable Code requirements.
(c)
Relief Valves:
(1)
Relief valves which fail to function properly during testing shall be:
- 1) adjusted, 2) repaired, or 3) replaced and retested to show acceptable operation. Procedure credit may be taken for valves that are tested by the vendor/manufacturer provided that similar test methods are used and the documentation verifies that the Surveillance Procedure acceptance criteria have been met.
(2)
Requirements for testing additional valves-the following requirements shall be adhered to:
- a.
Class 1, 2, and 3 Safety and Relief Valves: For each valve tested which the as-found set-pressure exceeds the greater of either the
+/- tolerance limit of the owner-established set-pressure acceptance criteria or +/- 3% of valve nameplate set-pressure, two additional valves shall be tested from that same valve group.
b Class 1, 2, and 3 Safety and Relief Valves: If the as-found set-pressure of any of the additional valves tested exceeds the criteria noted therein, then all remaining valves of that same valve group shall be tested
- c.
Class 1, 2, and 3 Safety and Relief Valves: Each valve that fails to comply with the set-pressure acceptance criteria shall have the cause and effect evaluated. Based upon this evaluation, PNPS will determine the need for additional tests required to address any generic concerns which could apply to the valves in the same or other valve groups 8.1.1.1 Rev. 15 Page 32 of 179

- - Denotes a check valve exercise open test or exercise close test that is not refueling outage dependent and may be performed more frequently than once a refueling interval Note 2.
Performance of PNPS 8 5 3 18* also satisfies the CT test requirement Note 3 If work is performed on these check valves that requires a postmaintenance test (using PNPS 8 5 3 18') and plant conditions do not allow conduct of PNPS 8 5 3 18*, then an exercise/examination using PNPS 3 M 4-53 must be satisfactorily completed for operability 8.1.1.1 Rev. 15 Page 41 of 179

RELIEF REQUESTED:
BASIS FOR RELIEF:
ISTB 5.2.1, Group A Test. Group A tests shall be conducted with the pump operating at a specified reference point. The test parameters shown in Table ISTB 4.1-1 shall be determined and recorded as required by this paragraph. The test shall be conducted as follows.
ISTB 5.2.1(b): For centrifugal and vertical line shaft pumps, the resistance of the system shall be varied until the flow rate equals the reference point. The differential pressure shall then be determined and compared to its reference value. Alternatively, the flow rate shall be varied until the differential pressure equals the reference point and the flow rate determined and compared to the reference flow rate value.
Obtain inservice test parameter values with two pumps running in parallel. When plant operating conditions allow scheduled single pump operation, perform the quarterly testing using single pump operation.
Reactor Building Closed Cooling Water System instrumentation is not configured to measure individual pump flow rates during plant parallel pump operations in a single loop. Pumps in a single loop have only a hand-operated butterfly valve capable of establishing the reference point value (not an acceptable throttling device).
Redesign of the system would be necessary to install flow instrumentation, to utilize portable flow instrumentation, or to provide an acceptable throttling device. Piping configuration does not permit installation of flow orifices on the pump discharge piping that would be consistent with good instrument practices. Each RBCCW loop has three pumps. Adequate distance downstream of the elbows is not available on the individual pump discharge prior to where discharge piping joins a common header.

PUMP RELIEF REQUEST PR-01 (CONTINUED)
The Reactor Building Closed Cooling Water System is part of the ultimate heat sink for containment cooling functions and Reactor Vessel shutdown cooling. Test loops do not exist for individual pump flow tests; therefore, disturbance of the system normal configuration during operation (and some cold shutdown conditions) will have a negative impact on the plant's ability to maintain safe steady-state operation.
The Reactor Building Closed Cooling Water pump system flow rates depend on Reactor power, service water temperature, and other climatic conditions. When plant service water heat loads are high and/or salt service water inlet temperature is high (during summer months), parallel pump operation is necessary. These conditions normally occur during the months of June, July, August, and September. Because of these limitations, the RBCCW Group A pump testing will be performed using one of two methods.
Scheduled testing during these conditions will be conducted in accordance with ISTB 5.3, Pumps in Regular Use. The Group A testing using parallel pumps will be performed using the same pump configurations (i.e., P-202A/B, P-202A/C, P-202D/E, or P-202D/F) at a known reference point of total flow. The use of parallel pumps allows monitoring both of the -pumps' hydraulic and mechanical parameters for degradation.
During periods when plant heat loads and climatic conditions allow the scheduled quarterly testing to be performed using single RBCCW pump operation, the Group A Test Method will be conducted using a single pump at a known flow reference point.
ALTERNATE TESTING:
Perform normal quarterly Type A pump testing while parallel pumps are in service. When plant heat loads and climatic conditions allow single pump quarterly testing to be scheduled in advance, the Type A test will be performed using a single pump.

BASIS FOR RELIEF:
ALTERNATE TESTING:
ISTB 4.2, Inservice Testing. Inservice testing of a pump in accordance with this Subsection shall commence when the pump is required to be operable (see paragraph ISTB 1.1).
Test the HPCI Main and Booster Pumps as an integral unit in accordance with ISTB 4.2(b) and ISTB 4.2(c).
There are no suitable provisions for accurately measuring the pressure in the crossover piping between the HPCI Booster and Main Pumps. Since these pumps are driven by a common driver and are connected in tandem, they are tested together, simultaneously, under the same operating conditions (flow rate and turbine speed). Therefore, measuring the inlet pressure of the booster pump and calculating the differential pressure of the pump combination will effectively verify operability and serve to monitor the performance of the pair.
During inservice testing of these pumps, the differential pressure of the pump combination will be determined from measurements of the suction and discharge pressures of the booster and main pumps, respectively. This data will be used to evaluate the performance of the pump combination in a manner such that the combination will be treated as a single multistage pump.

TEST REQUIREMENTS:
RELIEF REQUESTED' BASIS FOR RELIEF:
ISTB 5.2.3(d), Vibration (displacement or velocity) shall be determined and compared with corresponding reference values.
Vibration measurements are to be broad band (unfiltered). If velocity measurements are used, they shall be peak. If displacement amplitudes are used, they shall be peak-to-peak.
ISTB 5.2.3(e), All deviations from the reference values shall be compared with the ranges of Tables ISTB 5.2.1-1 and ISTB 5.2.3-1 and corrective action taken as specified in paragraph ISTB 6.2.
The vibration measurements shall be compared to the relative and absolute criteria shown in the Alert and Required Action Ranges of Table ISTB 5.2.1-1. For example, if vibration exceeds either 6 Vr or 0.7 in./sec, the pump is in the Required Action Range.
PNPS proposes to expand the Acceptable Range and Alert Range identified in Table ISTB 5.2.1-1 during Comprehensive pump testing. In addition, the resonance peaks will be evaluated during each test with an upper limit assigned.
Historical testing and analysis performed on the HPCI System by PNPS and the pump manufacturer have consistently revealed characteristic pump vibration levels that exceed the acceptance criteria stated in Table ISTB 5.2.1-1. The demonstration of high vibration levels during HPCI pump testing is a common phenomenon in the industry with like or similar design configurations of turbine-driven main and booster pumps. The PNPS HPCI pump exhibits vibration characteristics that have been diagnosed by the vendor (Byron Jackson) as being due primarily to a hydraulic standing wave resonance in the interconnecting piping at the booster pump vane pass frequency (4x RPM) coinciding with structural resonances of the piping and the main pump. This results in high vibration on the main pump bearing housings appearing at approximately 2x RPM in the horizontal direction but caused by the booster pump excitation at 4x RPM of the booster pump. Prior to Byron Jackson's Tech Note on high vibration, it was often misdiagnosed as being caused primarily by misalignment of the turbine to the main pump which would also induce high 2x RPM vibration. The vibration characteristics of the HPCI pump are predominantly a function of the pump design and should be identified as such rather than attributed to pump degradation. The high vibration has been present to the same order of magnitude since the pump was new.

PUMP RELIEF REQUEST PR-03 (CONTINUED)
Table ISTB 5.2.1-1 of the OM Code establishes an Alert Range of > 2.5Vr to 6Vr or > 0.325 to 0.7 in./sec and a Required Action Range of > 6Vr or
> 0.7 in./sec. In addition, footnote 1 to ISTB 4.4 states "Vibration measurements of pumps may be foundation, driver and piping dependent.
Therefore, if initial vibration readings are high and have no obvious relationship to the pump, then vibration measurements should be taken at the driver, at the foundation, and on the piping and analyzed to ensure that the reference vibration measurements are representative of the pump and that the measured vibration levels will not prevent the pump from fulfilling its function."
Assuming that "high" readings include those that exceed 0.7 in./sec peak, it can be shown that the main pump vibration occurring at 4x RPM of the booster pump is not related to the condition of the main pump. The high vibration is caused by hydraulic and structural resonances that are excited by the vane passing frequency at 4x RPM of the booster pump. The actual vibration of interest at the main pump includes only those frequency components generated by the rotor dynamics of the pump itself which include 1/2x, lx, and 2x RPM, and at the main pump vane passing frequency (5x RPM) and its related harmonics.
If this vibration frequency component at 4x booster pump RPM is subtracted from the main pump vibration spectrum, then the remaining vibration which is attributed to the main pump is below the OM Code Required Action Range.
This corrected vibration level provides a more representative measurement of the pump condition to be used for trending.
This method of vibration level correction was applied to historical spectrums.
The 4x booster pump RPM component was taken out of the calculation for the main pump overall vibration level. This data shows that when the 4x booster pump RPM component is deleted from the main pump vibration, the level is below the Required Action Range (> 0.7 in./sec) but still within the Alert Range (> 0.325 in./sec).
Although existing vibration levels of the HPCI pump are higher than the acceptance criteria provided in Table ISTB 5.2.1-1, they are acceptable and reflect the unique operating characteristics of the HPCI pump design configuration. It has been concluded that there are no major vibrational concerns that would result in pump degradation or would prevent the HPCI pump from performing its design safety function.

RELIEF REQUESTED:
BASIS FOR RELIEF:
ISTB 4.7.1(f) Frequency Response Range. The frequency response range of the vibration measuring transducers and their readout system shall be from one-third minimum pump shaft rotational speed to at least 1000 Hz.
Allow frequency response range to exceed the one-third minimum pump shaft rotational speed when the vibration measuring equipment will be 7.0 Hz or less.
The nominal shaft rotational speed of these pumps is 420 RPM which is equivalent to approximately 7.0 Hz. Based on this frequency and ISTB 4.7.1(f), the required frequency response range of instruments used for measuring SLC pump vibration is from 2.3 Hz to 1000 Hz. Procurement and calibration of instruments to cover this range to the lower extreme (2.3 Hz) are impractical due to the limited number of vendors supplying such equipment and the level of sophistication and cost of the equipment.
These pumps are of a simplified, reciprocating (piston), positive displacement design with rolling element bearings, Model Number TD-60, manufactured by Union Pump Corporation. Union Pump Corp. has performed an evaluation of the pump design and has determined that there are no probable subsynchronous failure modes associated with these pumps under normal operating conditions. Furthermore, there are no known failure mechanisms that would be revealed by vibration at frequencies below that related to shaft speed (7.0 Hz); thus, no useful information is obtained below this frequency nor will indication of pump degradation be masked by instrumentation unable to collect data below this frequency.
The requirement to measure vibration with instruments with response to one-third shaft speed stems from the need to detect oil whip or oil whirl associated with journal bearings. In the case of these pumps, there are no journal bearings to create these phenomena; thus, satisfying the frequency response range criteria would serve no significant purpose. The significant modes of vibration with respect to equipment monitoring are as follows:
1 - Times Crankshaft Speed - An increase in vibration at this frequency may be an indication of rubbing between a single crankshaft cheek and rod end, cavitation at a single valve, or coupling misalignment.
8.1.1.1 Rev. 15 Page 99 of 179
PUMP RELIEF REQUEST PR-04 (CONTINUED)
[4]
2 - Times Crankshaft Speed - An increase in vibration at this frequency may be an indication of looseness at a single rod bearing or crosshead pin, a loose valve seat in the fluid cylinder, a loose plunger/crosshead stub connection, or coupling misalignment.
Other Multiples of Shaft Speed - An increase in vibration at other frequencies may be indications of cavitation at several valves, looseness at multiple locations, or bearing degradation.
The vibration sensing instruments utilized by PNPS are accelerometers. Accelerometers have a frequency response range which is ideally suited for component operation but inherently have amplitude distortions at low frequencies. While other types of transducers may provide more accurate signals in a lower frequency response range, the advantages of accelerometers (light-weight, rugged, wide frequency response, good temperature resistance, moderate pricing, availability) would outweigh the advantages of having instrumentation that would meet the Code requirements for the SLC pumps. Additionally, as part of the PNPS Preventive Maintenance Program, the SLC pumps are subject to periodic vibration analysis and also receive periodic oil analysis.
Based on the foregoing discussion, it is clear that monitoring pump vibration within the frequency range of 7 to 1000 Hz will provide sufficient information for evaluating pump condition and ensuring continued pump reliability. Compliance with the Code requirement would result in a significant hardship and cost without any compensating increase in pump performance.
ALTERNATE TESTING:
Vibration levels of the Standby Liquid Control Pumps will be measured in accordance with the applicable portions of ISTB 4.7.1(f), Frequency Response Range, with the exceptions of the lower frequency response limit for the instrumentation. In this case, the lower response limit of the vibration measuring equipment will be 7 Hz or less.

ISTC 4.2.2(f): Valves full-stroke exercised at cold shutdowns shall be exercised during each cold shutdown, except as specified in paragraph ISTC 4.2.2(g). Such exercise is not required if the time period since the previous full-stroke exercise is less than 3 months.
BASIS FOR Full stroke testing [full stroke exercise (FE) and stroke timing (ST)]
JUSTIFICATION:
the MSIVs requires a reduction in power to approximately 60% or less in order to lower main steam line flow to acceptable levels for valve stroking.
Attempting to full stroke an MSIV above 60% power may result in a plant trip as the MSIV goes closed due to a steam flow increase through the other (nontested) lines. Conducting power reductions for the purpose of performing MSIV quarterly exercising is costly and burdensome to the utility.
The MSIVs are designed to receive a partial stroke exercise at 100%
power. Testing is accomplished by bleeding down the air from the actuator underpiston area (which holds this valve in the open position) and allowing the valve's springs to slowly move the poppet to the 10% closed (90% full open) position. Periodic partial stroke exercising is required by plant Technical Specifications and verifies proper open position indication, limit switch actuation, and fail-safe initiation.
A roller arm limit switch assembly activates the MSIV closed position light for full stroke exercise (FE). This limit switch assembly was not designed to provide precise valve stem position. The PNPS fail-safe closed verification no longer relies upon the closed limit switch mechanism. This is because valve full stroke stem travel may not always be accurately indicated by the activation of the close limit switch mechanism (and light indication).

COLD SHUTDOWN JUSTIFICATION CS-05 (CONTINUED)
Performing MSIV full stroke testing on a strict quarterly frequency during power operation will require periodic power reductions for testing, which creates an undue hardship without a compensating increase in the level of quality and safety. Fail-safe "springs-only" testing the outboard MSIVs is initiated by push button manipulation from the Control Room. Each valve's air control system has a special test circuit that enables a closure test to be conducted without using air assist from the valve actuator (closing) over-piston. The Control Room push button actuates a two-way solenoid valve that slowly vents (through a bleedoff port) the valve actuator's underpiston (opening) air supply. Spring force and the (pre-established) air bleedoff rate determine the resulting MSIV closure speed.
NUREG-1482, Guidelines for Inservice Testing at Nuclear Power Plants, Section 4, "Supplemental Guidance on Inservice Testing of Valves",
provides guidance related to MSIV fail-safe closure verification.
Section 4.2.4, "Main Steam Isolation Valves", endorses the General Electric Co. recommended practice (reference SIL 477) for conducting a "springs only" full stroke closure test and states "by monitoring position indicators alone, the utility could not determine that the valve is fully closed" and that testing "would necessitate measurement of the actual valve stem travel because the final 10-percent of stem travel coincides with the weakest spring force." Because PNPS has adopted the NUREG 1482 recommended practice, fail-safe testing requires: 1) valve access for marking stem position, 2) closure of the MSIV by normal means (which allows full closed stem position marking), and 3) "springs-only" closure verification using the field observed stem position.
To conduct periodic fail-safe testing to the outboard MSIVs (requiring access to the Steam Tunnel) during power operations is not consistent with PNPS ALARA practices. To perform the necessary preparations and obtain the required verifications during valve stroking requires personnel to spend an extended time in the Steam Tunnel during power operation and is beyond the reasonable task scope complexity utilized for quarterly valve stroke testing. Therefore, the outboard MSIVs (AO-203-2A through 2D) will be fail-safe tested at a cold shutdown frequency.
Access restrictions for fail-safe testing of the inboard MSIVs (AO-203-1A through 1D, located within primary containment) differ and are addressed within the appropriate Refuel Outage Justification.

For those cases when full stroke testing cannot practically be conducted during a plant downpower, valve stroking will be attempted again during the next scheduled plant downpower.
Full stroke testing of the MSIVs will also be performed during cold shutdowns when the quarterly test interval has been exceeded.

ISTC 4.5.2(f: All valve testing required to be performed during a refueling outage shall be completed before returning the plant to operation.
This check valve is the outboard primary containment isolation valve for a system considered in-service during plant operation. The exercise open test is performed by verifying system flow during normal operation and may precede or follow the exercise close test.
Performance of a check valve closure test during plant operaticon would result in the isolation of "A" and "B" Loop Drywell Coolers and "A" and "B" Loop Recirculation Pump Seal Water and Motor Lube Oil Coolers.
Isolation of those coolers associated with the recirculation pumps will lead to the accelerated degradation or failure of recirculation pump seals and may damage recirculation pump motors due to overheating. Additionally, isolation of the Drywell coolers during operation would impact the equipment environmental qualification requirements due to Drywell heatup.
Decay heat removal is a key safety function as defined by PNPS during cold shutdown. Due to this concern, PNPS Procedures often require that at least one recirculation pump remains in operation during cold shutdown to compensate for a potential loss of decay heat removal. The required isolation to test valve 30-CK-432 would isolate cooling to both recirculation subsystems causing the same failure concerns addressed above.
Additionally, isolation of Drywell coolers during cold shutdown will expose the Drywell to repeated unnecessary heatup with potential to adversely affect component operating life and habitability requirements.
Permanent plant-installed, nonintrusive test equipment does not exist for this valve. Other methods using portable equipment (e.g., acoustic, ultrasonic, magnetic, and radiography) which can be used to verify an open or close test on this valve require valve closure for extended periods and, as previously stated, are not practical for quarterly or cold shutdown testing.

BASIS FOR JUSTIFICATION:
ALTERNATE TESTING:
These check valves are the inboard and outboard primary containment isolation valves for a system considered in-service during plant operation.
Verification of the closure of these check valves during plant operation would require isolation of all feedwater flow to the vessel (the feedwater trains are crosstied). Such an evolution creates an adverse operating condition which would cause automatic plant shutdown due to loss of feedwater flow.
Performing an exercie close test during cold shutdowns would create prolonged periods of system testing and unreasonable increases in radiation exposure. Permanent plant-installed, nonintrusive test equipment does not exist for verifying disc position of these valves. Other methods using portable test equipment (e.g., acoustic, ultrasonic, magnetic, and radiography) which may be used in performing an exercise close test for these check valves during a plant cold shutdown have been reviewed and determined not to be practical. Portable methods require special test equipment to be installed and benchmarked prior to gathering final test data. This benchmarking also necessitates repeated feedwater system startup and shutdown operations which require excessive system manipulation during plant cold shutdown conditions. These alternate testing methods either require extended system testing to perform and/or cannot consistently provide accurate reliable results when utilized within the time constraints necessary for cold shutdown testing. Therefore, the only practical method available to verify check valve closure is during the performance of leak testing. Verifying a close test more frequently than that used for seat leak testing would create a hardship without a compensating increase in the level of safety. Leak testing (in accordance with 1 OCFR50 Appendix J) ensures the valve is in the closed position.
The exercise open test is performed by verifying system feedwater flow during plant operation and may precede or follow the exercise close test (using a leak test).
Perform the exercise close test of these check valves during a refueling outage not to exceed a refueling interval and complete testing prior to returning the plant to operation.

These check valves are the primary containment isolation valves for a system considered in-service during plant operation. The open function of these valves is non-safety related. The exercise open test is performed by verifying system flow during normal system operation and may precede or follow the exercise close test.
The performance of an exercise close test during plant operation would require isolation of recirculation pump seal purge lines. Operation of the recirculation pumps without seal purge has been shown to lead to accelerated degradation of pump seals. Additionally, leak testing to verify valve closure would require opening a connection on the seal purge line outside of the Drywell. This may introduce air into the seal purge system requiring venting to avoid rapid degradation of recirculation pump seals.
Venting of the seal purge line following testing would require Drywell access which is only accessible during cold shutdown.
The required isolation to test these check valves during plant cold shutdowns would result in the isolation of the recirculation seal purge lines, causing the same failure concerns addressed above. Decay heat removal is a key safety function as defined by PNPS during cold shutdown.

This is the HPCI exhaust drain pot containment isolation check valve which provides the flow path that allows condensate that collects between the HPCI inboard and outboard exhaust line check valves to drain into the HPCI exhaust line drain pot. This valve provides a containment isolation barrier in the closed position.
TEST REQUIREMENT: -
ISTC 4.5.2(c): If exercising is not practicable during plant operation and cold shutdowns, it shall be performed during refueling outages.
ISTC 4.5.2(f): All valve testing required to be performed during a refueling outage shall be completed before returning the plant to operation.
BASIS FOR JUSTIFICATION:
This normally closed valve must be exercise open tested by performing a specialized test. The exercise open test may precede or follow the exercise close test (using leak test methods). Performing this test at power would require isolation of the HPCI turbine for safety reasons. This will require HPCI to be inoperable during preparation, testing, and restoration of this system.
To conduct the exercise open test requires a temporary hydraulic supply established by installing a test hose from the plant demineralized water system to the HPCI exhaust line. Then the highest flow rate achievable through the 3/4" test hose is established to flood up the leg of piping upstream from this check valve. The introduced water then flows through CK-2301-218 and into the HPCI exhaust line drain pot, raising the level in the drain pot and causing the high level alarm to annunciate. The rate of flow is then calculated based on the time lapsed between introducing the water flow into the exhaust line and receiving the drain pot high level alarm. Due to the nature of the piping configuration, occasionally the drain rate into the drain pot becomes impaired due to air binding, preventing this test from providing the desired observed result. For these cases, the HPCI exhaust line piping and thedrain pot must be manually vented and drained, and the test rerun to achieve a satisfactory exercise open test.

REFUEL OUTAGE JUSTIFICATION RJ-04 (CONTINUED)
Performing an exercise open test during power operations or cold shutdowns is impractical because it is intrusive and renders the HPCI System inoperable for an extended period of time. To verify this valve open using flow it is necessary to take the HPCI System out of service, set up a special hydraulic test supply, install system vent and drain hoses, perform forward flow testing, drain down the remaining water from the HPCI exhaust line, remove test equipment, and restore the system to operable status. Even during cold shutdowns, to create the system conditions and conduct testing for this check valve, the HPCI System must be made inoperable for an extended period of time such that it could delay returning the plant to power (approximately 8 to 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br />).
Permanent, plant-installed, nonintrusive test equipment does not exist for this valve. Other methods using portable equipment (e.g., acoustic, ultrasonic, magnetic, and radiography) which could be used in verifying an open test would still require a temporary test circuit to establish the conditions for conducting the test. Also, because this is a steam line drain line, it is difficult to ensure the drain piping is maintained completely free of air voids during testing, which will render some methods unreliable.
All methods mentioned above for conducting an exercise open test either require extended system outages to perform and/or cannot consistently provide accurate reliable results when utilized within the time constraints necessary for cold shutdown testing.

These normally closed valves are exercise open tested by performing a specialized flow test. The exercise close'test of each valve is verified concurrently with the exercise open test by performing an air leakage test.
Testing these valves at power requires isolation of the HPCI turbine for safety reasons. This requires HPCI to be inoperable during preparation, testing, and restoration of this system.
To conduct the exercise open test, an air test flow instrument with a pressure gauge is connected to the vacuum breaker system using a test hose and a system vent path is established. Then the desired air flow rate is achieved through these check valves while the test cart air makeup pressure is monitored. The test is satisfactory when a specified rate of flow is established without exceeding a maximum backpressure. To perform the exercise close test of this valve, a leak rate monitor with an installed pressure gauge is connected to the vacuum breaker system using a test hose and a system vent path is established. Two separate air leak rate tests are conducted to ensure that each valve returns to its closed position. These tests are satisfactory when a specified leakage rate which is indicative of full valve closure is achieved.

To conduct an exercise open test requires installing an ultrasonic flow meter onto the LPCI minimum flow piping. Then, the respective pump is run while system flow is throttled to maximize pump flow through the minimum flow path. Due to their size and configuration, these minimum flow lines typically experience high flow turbulence that can impair test conduct.

On some occasions immediately following a HPCI pump run, there is sufficient level in the GSC to permit valve stroke testing. However, if the GSC pump begins to pump down within 2 to 3 minutes before the HPCI pump is tripped or while the HPCI System is being secured following pump trip, then the GSC low level permissive will not be clear and the valve cannot be stroked using the control switch. In this case, valve stroking may not be possible for extended periods of time. Restarting HPCI to obtain another chance for valve stroking would place undue wear and tear on the HPCI turbine/pump system and would be burdensome.
A review of plant on-line computer data for the GSC system shows that when the HPCI System is in the standby mode a low level permissive may not clear for weeks or months to allow stroking the AO-2301-64 valve.
This is due to zero or very low steam leakage past the HPCI steam admission valve (a new design valve was installed during RFO #10 which greatly diminished steam leakage).
Testing this valve on a quarterly basis would cause an undue hardship.
To conduct a full stroke exercise (FE) and stroke time (ST) consistently on a quarterly basis, one of the following measures will need to be implemented: 1) water must be manually introduced into the HPCI GSC shell side by installing a temporary hose that supplies water from either the HPCI pump suction (using CST static head pressure) or the plant demineralized water system or 2) the low GSC water level permissive that prevents stoking this valve using the control switch must be defeated by installing an electrical jumper.
Stroking the AO-2301-64 valve on a strict quarterly frequency during power operation will require conduct of one of the above listed special provisions and renders the HPCI System inoperable for an extended period of time (several hours). Even during cold shutdowns, to create the system conditions and conduct testing of the air-operated valve, the HPCI System must be made inoperable for an extended period of time such that it could delay returning the plant to power. To create the conditions that will allow stroke testing quarterly or during cold shutdown is burdensome and creates an undue hardship without a compensating increase in the level of quality and safety.

For those cases when this valve does not stroke following the HPCI quarterly pump test, valve stroke timing will be attempted again during the next scheduled HPCI pump run(s).

The alternate methods will either utilize: 1) leak testing using water or air to verify valve closure or

Valve No.(s) 9-CK-340 9-CK-341 31-CK-434 Description These valves are the inboard containment isolation valves (Type C tested) for the Drywell and Torus Nitrogen Makeup System. This makeup system is part of the Primary Containment Atmospheric Control System and ensures a source of nitrogen to maintain the inerted condition of containment. These valves are exercised periodically in the open direction.
The most practical method of the exercise close test is during an Appendix J seat leakage test or simplified closure test which also measures seat leakage. These tests require isolating the line to this penetration (which would make Containment Atmospheric Dilution System components unavailable) and installing test equipment. Therefore, testing to verify normal closed position more frequently than once each refueling interval results in a hardship and is not practicable due to an increase in personnel radiation exposure, loss of system availability, and manpower constraints.
This is an inboard containment isolation valve (Type C tested) in the air/nitrogen line which supplies a remote air-operated exerciser for exercising the Torus to Reactor Building Vacuum Breakers. This check valve is opened quarterly during vacuum breaker testing. The only practical method of the exercise close test is during an Appendix J seat leakage or simplified closure test which also measures seat leakage.
These tests require climbing to the top of the Torus to allow valve lineup and test equipment installation. This location is a high radiation area and difficult to access. Testing to verify closed position more frequently than once each refueling interval results in a hardship and is not practicable because of the increase in personnel radiation exposure and the safety risks associated with working on top of the Torus.

Description The exercise close test can only be performed by entering the containment (Drywell) environment, isolating components supplied by Drywell instrument air, and performing a closure test using leak test methods.
Drywell components which will be isolated include: inboard MSIVs and Main Steam Relief Valve Accumulators, equipment and floor drain sump instruments, and Drywell air-operated valves (i.e., Reactor head vent, Reactor sampling, and Reactor seal drain). To conduct an exercise close test other than during a refueling interval would result in a hardship and is not practicable due to excessive Drywell component isolation and an increase in personal radiation exposure.
This valve is part of the Reactor Coolant pressure boundary for the Standby Liquid (reactivity) Control (SLC) System. This check valve performs a containment isolation function and forms the Code Class break between Class 1 and Class 2 SLC piping. A seat leakage test or a closure test using seat leak methods is the most practical method for verifying the normally closed position. Because conducting an exercise open test requires initiating the SLC System and injecting into the Reactor Vessel (refer to RJ-16), nonintrusive methods to verify closure can only be conducted infrequently (once each refuel outage).
Therefore, verifying the exercise close test more frequently than once per refueling interval would create a hardship without a compensating increase in the level of safety.
These valves are containment isolation valves (Type C tested) between the HPCI turbine exhaust header and the suppression pool (Torus). The most practical method available to verify each valve's exercise close test is to perform an Appendix J seat leakage test or closure verification using leak test methods. This testing requires erection of scaffolding, isolation of the penetration, and installation of test equipment. Verifying the closed position more frequently than once each refueling interval would be a hardship and is not practicable due to increased personnel radiation exposure and prolonged periods of safety system inoperability.

Description These valves are water-tested containment isolation valves for the Core and Suppression Pool Cooling and Reactor Vessel Level Makeup systems.
These valves require testing to assure that the seal-water (Torus) fluid inventory is sufficient to maintain the sealing function for at least 30 days.
The most practical method available to verify each valve's exercise close test is to perform an Appendix J seat leakage test or closure verification using water leak test methods. Testing requires isolating the penetration, in some cases the erection of scaffolding, and installation of test equipment. Testing often requires personnel to enter high radiation areas.
Verifying the closed position more frequently than once each refueling interval would be a hardship without any compensating increase in the level of safety due to increased personnel radiation exposure and prolonged periods of safety system inoperability. The asterisked (*) valves are not required to be designated category "AC", but their exercise close test is normally performed (using leak test methods) in conjunction with the other valve seat leakage tests.

These check valves are the HPCI Turbine Exhaust Drain Line Check Valves.

ISTC 4.5.2(c): If exercising is not practicable during plant operation and cold shutdowns, it shall be performed during refueling outages.
ISTC 4.5.2(f): All valve testing required to be performed during a refueling outage shall be completed before returning the plant to operation.
These normally closed check valves (installed in series) are exercise open tested by the performance of a specialized flow test. The exercise close test is verified once per refueling interval by using seat leakage test methods.
Performing this test at power requires isolation of the HPCI turbine for personnel safety reasons. This requires HPCI to be inoperable during preparation, testing, and restoration of this system.
To conduct the exercise open test, a water flow rate monitor with an installed test gauge is connected to the HPCI Exhaust Drain Line using a test hose. The exercise open test is achieved by observing flow through both check valves to the Torus.
Performing an exercise open test during power operation or cold shutdowns is impractical because it is intrusive and renders the HPCI System inoperable for an extended period of time. To verify these valves open using flow, it is necessary to take the HPCI System out of service, set up a flow meter with a hydraulic test supply, install the test flow meter, perform an exercise open test and restore the system to operable status.
Even during cold shutdowns, to create the system conditions and conduct testing for this check valve exercise, the HPCI System must be made inoperable for an extended period of time (approximately 10 to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />) such that it could delay returning the plant to power.

Other methods using portable equipment (e.g., acoustic, ultrasonic, magnetic, and radiography) which could be used in verifying an open test would still require a temporary test circuit to establish the conditions for conducting an open test. Also, because this is a steam exhaust drain line, it is difficult to ensure the drain piping is completely free of air voids during testing, which will render some methods unreliable.
All methods mentioned above for conducting an exercise open test require extended system outages to perform and/or cannot consistently provide accurate reliable results when utilized within the time constraints necessary for cold shutdown testing.

The check valves relieve pressure buildup which protects the normally closed gate valve from a pressure locking or thermal binding condition during certain system heatup and cooldown evolutions.

To conduct the OM Code exercise test (both open and close tests) for these valves, a leak rate monitor with an installed pressure gauge is connected to the equalizing line using a test hose and a system vent path is established. The exercise open test is conducted by establishing the acceptance flow rate through the check valve. Then, through valve manipulation and test equipment realignment, an exercise close test is performed by using seat leakage test methods, the test equipment is removed, and the loop is restored to operable status following system venting, valve realignment, and proper verifications.

Performing an exercise open test during cold shutdowns is impractical because it is intrusive and may render the RHRJLPCI Injection Loop inoperable for an extended period of time.

TEST REQUIREMENT:
ISTC 4.2.6, Fail-Safe Valves. Valves with fail-safe actuators shall be tested by observing the operation of the actuator upon loss of valve actuating power in accordance with the exercising frequency of paragraph ISTC 4.2.1.
BASIS FOR Fail-safe "springs-only" testing of the inboard MSIVs is initiated by push JUSTIFICATION:
button (switch) manipulation from the Control Room. Each valve's air control system has a special test circuit that enables a closure test to be conducted without using air assist from the valve's over-piston (closing) actuator. The Control Room push button actuates a two-way solenoid valve that slowly vents (through a bleedoff port) the valve actuator's underpiston (opening) air supply. Spring force and the (pre-established) air bleedoff rate determine the resulting MSIV closure speed.
A roller arm limit switch assembly activates the MSIV closed position light for full stroke exercise (FE). This limit switch assembly was not designed to provide precise valve stem position. The PNPS fail-safe closed verification no longer relies upon the closed limit switch mechanism. This is because valve full stroke stem travel may not always be accurately indicated by the activation of the close limit switch mechanism (and light indication).
NUREG-1482, Guidelines for Inservice Testing at Nuclear Power Plants, Section 4, "Supplemental Guidance on Inservice Testing of Valves",
provides guidance related to MSIV fail-safe closure verification.
Section 4.2.4, "Main Steam Isolation Valves", endorses the General Electric Co. recommended practice (reference SIL 477) for conducting a "springs only" full stroke closure test and states "by monitoring position indicators alone, the utility could not determine that the valve is fully closed" and that testing "would necessitate measurement of the actual valve stem travel because the final 10-percent of stem travel coincides with the weakest spring force." Because PNPS has adopted the NUREG 1482 recommended practice, fail-safe testing requires: 1) valve access for marking stem position, 2) closure of the MSIV by normal means (which allows full closed stem position marking), and 3) "springs-only" closure verification using the field observed stem position.

The inboard MSIVs are located in the Drywell (primary containment) and are not accessible during normal plant operations. The Drywell is normally inerted with nitrogen during power operations and often remains de-inerted during plant cold shutdowns.

Therefore, the inboard MSIVs (AO-203-1A through 1D) will be fail-safe tested at a cold shutdown frequency when the Drywell is de-inerted.

The valve opens to allow the vacuum pump to discharge air and noncondensable gases from the RCIC (Barometric Condenser) Vacuum Tank to the Torus. This valve closes to prevent Torus water backflow into the RCIC Vacuum Tank during Torus (accident conditions) pressurization.
TEST REQUIREMENT:
ISTC 4.5.2(c): If exercising is not practicable during plant operation and cold shutdowns, it shall be performed during refueling outages.
ISTC 4.5.2(f): All valve testing required to be performed during a refueling outage shall be completed before returning the plant to operation.
BASIS FOR JUSTIFICATION:
This normally closed valve must be exercise open tested by performing a specialized flow test and the exercise close test is conducted by performing an air leakage test.
This testing during normal operation or cold shutdown would cause undue hardship. Performing these tests at power would require isolation of the RCIC turbine for safety reasons. This will require RCIC to be inoperable during preparation, testing, and restoration of this system.
To conduct the exercise open test, an air test flow instrument with a pressure gauge is connected to the vacuum pump exhaust line using a test hose and a system vent path to the Torus is verified. Then the desired air flow rate is achieved through the check valve while the test cart air makeup pressure is monitored. The test is satisfactory when a specified rate of flow is established without exceeding a maximum backpressure.
Performing an exercise open test during power operations or cold shutdowns is impractical because it is intrusive and renders the RCIC System inoperable for an extended period of time. To verify this valve open using flow, it is necessary to take the RCIC System out of service, set up special test equipment, establish a vent path, and perform exercise open testing. Then the system must be realigned, test equipment removed, and the system restored to operable status. Even during cold shutdowns, to create the system conditions and conduct testing for this check valve exercise open test, the RCIC System must be made inoperable for an extended period of time such that it could delay returning the plant to power.

BASIS FOR JUSTIFICATION:
These normally closed valves must be exercise open tested by conducting a specialized nonintrusive test (NIT) or during a flow test that injects water into the Reactor Vessel via the Core Spray System. These valves are normally closed, which maintains system keepfill pressure by preventing backflow through the secured pump. These valves must open to allow Core Spray injection flow to the Reactor Vessel. The exercise close test is conducted during the quarterly pump test.
Testing these valves during normal operation by measuring system flow would require injecting cold water into the Reactor Vessel using the Low Pressure Core Spray System. The Core Spray Pumps cannot provide sufficient head to inject into the Reactor Vessel during normal operation.
Valve testing using flow during cold shutdown could cause a thermal shock to the Reactor Vessel and spray sparger when the vessel metal temperature is greater than 212 0F.
The suppression pool is the Core Spray System's water source. Injection of suppression pool water into the Reactor Vessel during cold shutdown results in exceeding the EPRI Water Chemistry Guidelines which PNPS has adopted to preclude the initiation and propagation of intergranular stress corrosion cracking in Reactor coolant stainless steel components.
The chemistry of the suppression pool water (typical conductivity of 4 to 5 gmho/cm) does not meet the chemical requirements of the Reactor coolant (typical conductivity of 0.15 to 0.3 gmho/cm).

Testing these valves during cold shutdown could cause a thermal shock to the Reactor Vessel when the vessel metal temperature is greater than 2121F.

Restart of the Reactor is not permitted until the Reactor coolant water chemistry is within the EPRI Guidelines.
In addition, the amount of water that is injected into the vessel during the test of only one of the Core Spray injection check valves results in significant vessel level increase and may cause a vessel isolation.

BASIS FOR JUSTIFICATION:
To verify forward flow during normal operation or cold shutdown would require firing a squib valve and injecting water into the Reactor Vessel using the SLC pumps. Injecting water during operation could result in adverse plant conditions such as changes in reactivity, power transient, thermal shock-induced cracking, and possible plant trip. Injecting water during a cold shutdown can result in cyclical thermal shock-induced cracking as cold water enters the Reactor Vessel, which is at an elevated temperature due to decay heat.
Injection of the SLC System during cold shutdowns using demineralized water requires a lengthy flushing operation to remove boron from the system. Even after extensive flushing, boron remains present in system dead legs. Some of this boron propagates into the Reactor Vessel during injection and is difficult to remove from the system. The presence of boron in Reactor water impedes the plant ability to achieve criticality for plant startup.

These air-operated valves are stroked closed quarterly using a separate testing air vent (bleed) circuit. Stroke times using the test circuit can only verify the valve's closed exercise since the closing stroke times are very erratic. Timing of the valve's close stroke using the test circuit quarterly provides meaningless data for tracking valve performance. The only method available to close stroke-time these valves is by initiating a Reactor Scram. Trending these valves in the closed direction by Scramming the Reactor quarterly is impractical. Valve open stroke times are measured and trended quarterly to monitor for valve degradation.
Once per refueling outage, in accordance with Technical Specifications, a full Reactor Scram is initiated which utilizes the normal vent circuit for these valves. Since the Technical Specifications surveillance requirement is being satisfied, then the test frequency assures that the necessary quality of systems and components is maintained, that facility operation will be within the safety limits, and that the limiting condition for operation will be met.

The listed components supply numerous plant systems required for safe plant operation. The recirculation pumps and Drywell coolers may be required to support the plant during cold shutdown conditions to prevent water stratification in the vicinity of Reactor Vessel lower head and overheating of Drywell components.
Exercising these valves quarterly during power operation is impractical because the resulting flow interruption could cause equipment damage.
It also is impractical to exercise these valves during cold shutdown when Drywell cooling loads are high or when a Reactor recirculation pump is operating.

Closure of these valves during normal operation will result in loss of forced circulation to the Reactor, prohibited by PNPS license.
Closure of these valves during cold shutdown necessitates securing operation of the Reactor recirculation pumps. This is detrimental because even though the moderator temperature is less than 2121F, the recirculating system is usually kept in operation during cold shutdown to provide Reactor coolant mixing to prevent Reactor Vessel temperature stratification. The Reactor Vessel temperature profile takes on an increasing temperature gradient between the bottom vessel head and the shutdown core when mixing (forced circulation) is stopped. Additionally, the water in the idle recirculation loops cools down. This stratification can have the following adverse effects: Reactor Vessel temperatures become greater between the vessel bottom and top resulting in unnecessary thermal cycling, startup of the shutdown recirculation pump can cause a cold water intrusion affecting Reactor Vessel metal temperatures.
Deliberate stopping and starting of the recirculation pumps 1) creates unnecessary cycling wear on major equipment important to plant reliability and 2) could result in extending the shutdown, both of which would be costly and burdensome to the plant. Therefore, performing this testing on a cold shutdown or quarterly frequency is not practicable.

Valves 4085A and 4085B are the non-safety related component isolation valves for RBCCW Loop A. Components cooled by this RBCCW branch include the Reactor recirculation pump motor-generator set fluid coupling oil and bearing coolers.
Stroke testing quarterly during power operation could result in loss of cooling to the recirculation pump motor-generator set fluid coupling oil and bearing coolers with consequent loss of forced circulation to the Reactor, requiring plant shutdown.
Stroke testing at cold shutdown could result in loss of the recirculation pump operation due to interruption of cooling to the recirculation pump motor-generator set fluid coupling oil and bearing coolers. This is detrimental because even though the moderator temperature is less than 212°F, the recirculation system is kept in operation during cold shutdown to provide mixing of the Reactor coolant to prevent Reactor Vessel temperature stratification.

REFUEL OUTAGE JUSTIFICATION RJ-20 (CONTINUED)
The Reactor Vessel temperature profile takes on an increasing temperature gradient between the bottom vessel head and the core when mixing (forced circulation) is stopped, plus the water in the idle recirculation loops cools down. This stratification can have the following adverse effect: Reactor Vessel metal temperature differences become greater between Reactor Vessel bottom and top resulting in unwanted thermal cycling. Startup of the shutdown recirculation pumps causes a cold water intrusion which affects Reactor Vessel metal temperatures and causes thermal cycling of the Reactor Vessel.
ALTERNATE TESTING:
Exercise valves during a refueling outage not to exceed a refueling interval and complete testing prior to returning the plant to operation.

REFUEL OUTAGE JUSTIFICATION RJ-21 As Applicable Check valves, except Containment Isolation Check Valves, requiring seat leakage measurement for the performance of the closed test are as listed within this justification.
CATEGORY: AC 1, 2, and 3 FUNCTION:
These valves are required to return to their normally closed position to minimize seat leakage.
TEST REQUIREMENT:
ISTC 4.5.2(c): If exercising is not practicable during plant operation and cold shutdowns, it shall be performed during refueling outages.
ISTC 4.5.2(f): All valve testing required to be performed during a refueling outage shall be completed before returning the plant to operation.
BASIS FOR JUSTIFICATION:
These check valves are required to return to their normal closed position to perform a safety function and limit seat leakage to a specific amount.
Conducting a satisfactory seat leakage measurement assures the valve's obturator has returned to the normal closed position. Permanent, plant-installed, nonintrusive test equipment does not exist for verifying disc position for any of these listed valves. Other methods using portable equipment (e.g., acoustic, ultrasonic, magnetic, and radiography) which may be used in performing a closure verification on a quarterly or cold shutdown frequency have been reviewed and determined to be not practical. Portable methods require special test equipment to be installed and benchmarked prior to gathering final test data. These alternate testing methods either require extended system outages to perform and/or cannot consistently provide accurate reliable results when utilized within the time constraints necessary for quarterly or cold shutdown testing.
Therefore, attempting to verify the closed position by other positive means or by performance of seat leakage tests on a quarterly or cold shutdown basis is not practical and would place undue hardship on the plant. These valves are tabulated as part of this relief with a brief explanation of the unique hardship or impracticality of testing.
ALTERNATE TESTING:
Perform the exercise close test of these check valves during a refueling outage not to exceed a refueling interval and complete testing prior to returning the plant to operation.

Each valve performs a pressure isolation function between the Reactor coolant pressure boundary and the associated low pressure system. A seat leakage test is the only practical method for verifying the normally closed position. Testing these valves requires entry into the Drywell (e.g., Drywell must be de-inerted) for system isolation, installation of test equipment, and sometimes partial draindown of the system.
Therefore, verifying the exercise close more frequently than the interval used for seat leakage testing would create a hardship and is not practicable due to an increase in personnel radiation exposure and prolonged periods of safety system inoperability.
This valve is part of the Reactor coolant pressure boundary for the Standby Liquid (reactivity) Control (SLC) System. This check valve maintains the Reactor coolant pressure boundary for this high pressure system. A seat leakage test is the only practical method for verifying the normally closed position. Since there is no test connection upstream from this valve to enable pressurization, the closed position can only be practically verified by performing a leakage test during the Class 1 Reactor Pressure Vessel System Leakage Test. This system leakage test is only conducted near the end of each refueling outage. Because this valve is located inside the Drywell and conducting an exercise requires initiating the SLC System and injecting into the Reactor Vessel nonintrusive test methods for verifying valve closure are not practical.
Therefore, verifying the exercise close test more frequently than the interval used for leakage testing would create a hardship without a compensating increase in the level of safety.
These valves are the seismic boundary isolation between the Core Spray or LPCI suppression pool cooling systems and their keepfill supplies.
Loss of keepfill for maintenance or testing creates a potential for air intrusion which would jeopardize the affected cooling system's operability.
The only reasonable method to verify the valves' exercise close is by performing a seat leakage test. Leak testing of these valves requires isolation of the keepfill supply and entry into a radiation area to install test equipment and conduct testing. Therefore, verifying the closed position more frequently than the interval used for the seat leak testing would be a hardship and is not practicable due to increased personnel radiation exposure and prolonging the duration of a safety system's inoperability.

The only practical method for verifying their closed position is during a seat leakage test. This testing requires isolation of both SLC trains and removal of a pump discharge relief valve to establish a vent path. Therefore, verifying the closed position more frequently than that used for seat leakage testing creates a hardship and is not practicable due to prolonged periods of safety system inoperability.
These valves are Condensate Storage Tank (CST) water supply check valves for Reactor Core Isolation Cooling (RCIC) and High Pressure Coolant Injection (HPCI) Systems. The function of these normally closed check valves is to 1) open to supply the normal suction path for each system and 2) close to prevent backflow during system automatic swap to an alternate (Torus water) suction path. This closing prevents suppression pool water from being directed to the CST when the Torus is pressurized during severe accident conditions. The only practical method available to verify each valve's close position is during seat leakage testing. This testing requires isolating both suction paths and installing test equipment which renders the systems inoperable for an extended period of time.
Therefore, verifying the exercise close test more frequently than that used for seat leakage testing would be a hardship and is not practicable due to prolonged periods of safety system inoperability.

FUNCTION:
These normally open check valves are the pump discharge check valves which, when open, allow proper coolant flow and, when closed, prevent diversion of flow and reverse pump rotation.
TEST REQUIREMENT:
ISTC 4.5.2(c): If exercising is not practicable during plant operation and cold shutdowns, it shall be performed during refueling outages.
ISTC 4.5.2(f): All valve testing required to be performed during a refueling outage shall be completed before returning the plant to operation.
BASIS FOR JUSTIFICATION:
During plant operation these normally open check valves can be exercise close tested during quarterly pump testing. Because of each system's large cooling loads and lack of installed instrumentation, individual pump flow rates cannot be obtained. This deviation is identified by pump Relief Request PR-01 with an alternate testing criteria of measuring a total flow rate using parallel pumps. The individual check valve OM Code exercise test (both open and close tests) will be performed during the individual pump test when practical, but not to exceed a refueling interval basis.
Therefore, verifying the OM Code exercise open test quarterly or during each plant cold shutdown for these check valves may (at times) be impractical and would place an undue hardship on the facility.
ALTERNATE TESTING:
Perform the exercise open test during a refueling outage (not to exceed a refueling interval) or when plant conditions allow individual pump testing. Complete testing prior to returning the plant to operation.

Coolant Injection (LPCI) System and remain closed during normal plant operation. Each valve is an integral part of its respective RHR Shutdown Cooling loop flow path. One loop of RHR Shutdown Cooling is necessary for decay heat removal during a cold shutdown.
PNPS practice is to select an RHR Shutdown Cooling loop on a staggered basis each shutdown and remain exclusively in the selected loop for shutdown duration, unless changing plant conditions or maintenance activities necessitate shifting to the other loop. Swapping from one RHR loop to another creates a "higher risk evolution" because of 1) excessive manpower loading, 2) deviations from normal system configurations,
- 3) complexity of this task (i.e., high susceptibility to events causing the loss of key safety functions), and 4) large dose accumulations.
This method of devoting one loop to Shutdown Cooling for the shutdown duration is supported by the conclusions of NUMARC 91-06, Guidelines For Industry Actions to Assess Shutdown Management. This document references numerous NRC lENs and IEBs in which a loss of "key safety functions" (i.e., decay heat removal capability and inventory control) has occurred during "higher risk evolutions". Because of task complexity, swapping RHR Shutdown Cooling loops for the purpose of partial exercising these injection check valves creates a high risk evolution and should be avoided. For the case of mid-cycle and refueling outages, plant conditions/activities usually require swapping from one RHR loop to the other.

REFUEL OUTAGE JUSTIFICATION RJ-23 (CONTINUED)
Exercise open testing an injection check valve at the maximum required accident flow rate is only obtainable by operating three RHR pumps.
Normal plant limitations do not allow the operation of more than two RHR pumps within a loop. An exercise open test can be verified by performing diagnostic testing while two pumps pass flow through a Shutdown Cooling loop. This testing requires entry into primary containment (Drywell) and operation of special test equipment in a high radiation area.
Performing diagnostic nonintrusive monitoring of these valves on a refueling interval demonstrates that the full-stroke capability of each valve is acceptable.

ISTC 4.5.2(f): All valve testing required to be performed during a refueling outage shall be completed before returning the plant to operation.
BASIS FOR JUSTIFICATION:
Testing these valves during normal operation would require: 1) injecting cold water into the Reactor Vessel using the HPCI (or RCIC) System which would result in both a reactivity excursion and thermal shock to the feedwater nozzle and piping and 2) loss of one pressure isolation barrier between the high pressure Reactor coolant system and low pressure HPCI (or RCIC) System.
Performing the OM Code exercise test (both open or close tests) during cold shutdowns is prohibited due to differential pressure experienced across the valve disc. Additionally, access to the valve's exerciser adapter requires construction of temporary scaffolding (personal safety concern) thus increasing the testing duration.
These check valves are manually stroke testable. Since a maximum allowable torque on the mechanical test lever of 120 ft-lb for valve 2301-7 and 75 ft-lb for valve 1301-50 are specified by the manufacturer to prevent damage, the exercise open test is performed by use of the manual exerciser and applying normal force to move the obturator from the close seat to the full open position.
The exercise close test is conducted by repositioning the manual exerciser releasing obturator allowing the disc to move to the close seat. The valve disc weight and gravity return the obturator to the closed position. The manual exerciser is then positioned to the neutral position ensuring that the exerciser does not interfere with valve operational readiness.

These are the supply check valves for the Reactor water level reference leg purge system, which is required to be placed into service periodically (i.e., once every 30 days) during plant operation. These check valves are configured in series without provisions to verify individual reverse flow closure. The safety function for these valves is to close and isolate the reference leg purge system from the CRD System. The most practical way to perform the exercise close test is to conduct a seat leakage test which requires isolating CRD flow to the water level reference legs.
Conducting a leak test also requires breaching the system boundary and installation of test equipment for system pressurization and vent path. Isolating and breaching the Reactor water level purge system during power operation or plant cold shutdowns can negatively impact this system's function by creating a condition that allows the potential for air to be introduced into these reference legs.
Other methods (e.g., acoustics, ultrasonics, magnetics, and radiography) have been reviewed for performing a close test of these valves during cold shutdowns; however, they have been determined not practical. These alternate methods either require extended system outage time for testing and/or cannot consistently provide reliable test results due to the small size of these valves (0.375 inch with Swagelok fittings).
Therefore, verifying the OM Code exercise test (both open and close tests) will be during a refueling outage.

VALVE RELIEF REQUEST VR-01 (CONTINUED)
RELIEF REQUESTED:
BASIS FOR RELIEF:
Relaxation of the number of EFCVs tested every refuel outage from "each" to a "representative sample" every refuel outage (nominally once every 24 months). The representative sample is based on approximately 20 percent of the valves each 2-year cycle such that each valve is tested at least every 10 years (nominal).
NEDO-32977-A and the associated NRC Safety Evaluation, dated March 14, 2000, provide the basis for this relief. NEDO-32977-A justifies relaxing the EFCV testing frequency from the current testing of each valve once/cycle to an approximately 20% sample once/cycle such that each valve is tested within a 10-year interval.
NEDO-32977-A demonstrates, through operating experience, a high degree of reliability with EFCVs and the low consequences of an EFCV failure. Reliability data in the report (Tables 4-1 and 4-2) documents two EFCV failures (failure to close) at four participating plants (Monticello, Dresden, Vermont Yankee, and Oyster Creek) for Chemequip valves similar to those used at PNPS. These two failures were observed over a service time of 5426 operating years (4.75E+07 operating hours). This results in a "Best Estimate Failure Rate" of 4.21 E-08 per hour of operating time and an "Upper Limit Failure Rate" of 1.33E-07 per hour of operating time. A review of historical test surveillance data and a test failure component history search at PNPS shows zero EFCV failures (failure to close) have been observed (data from 1983 through 1999 RFO #12). In addition, there are no known EFCV failures that occurred earlier than 1983.
The instrument lines at PNPS have a flow restricting orifice upstream of the EFCVs to limit Reactor water leakage in the event of rupture.
Previous evaluations contained in PNPS's Updated Final Safety Analysis Report (FSAR) of such an instrument line rupture do not credit the EFCVs for isolating the rupture. Thus, a failure of an EFCV, though not expected as a result of this request, is bounded by the analysis. Based on NEDO-32977-A and the analysis contained in PNPS's FSAR, the proposed alternative to the required exercise testing frequency for EFCVs prescribed by OM-10 provides a satisfactory level of quality and safety.

VALVE RELIEF REQUEST VR-01 (CONTINUED)
ALTERNATE TESTING:
This Relief Request proposes to exercise close test, by full-stroke to the position required to fulfill its function, a representative sample of EFCVs every refueling outage. During the close test, gross valve seat leakage (LEF) will be measured. The representative sample is based on approximately 20 percent of the valves each cycle such that each valve is tested every 10 years (nominal). An exercise open test will be performed on each valve following the exercise close test and leak testing.
EFCV failures will be documented in PNPS's Corrective Action Program as a surveillance test failure. The failure will be evaluated and corrected. The Administrative EFCV Sample Test Program procedure will trend EFCV test failures and determine whether additional testing is warranted.
The Administrative EFCV Sample Test Program procedure will also establish a minimum acceptance criteria for Chemequip EFCVs of less than or equal to one failure per year (two failures per 2 years) on a 2-year rolling average. This requirement will ensure EFCV performance remains consistent with the extended test interval.
Upon exceeding the criteria, an evaluation will be required which will:
"* require a root cause evaluation to determine cause;
"* determine the extent of conditions;
"* require an evaluation of the testing interval to ensure reliability of the EFCVs; and
"* produce a risk analysis of the effects of the failures on cumulative and instantaneous plant safety.
Corrective actions and performance goals will be established based on the results of the root cause analysis.

A review of historical test surveillance data and a test failure component history search at PNPS show zero EFCV failures (failure to close) have been observed from 1989 through 1999 RFO 12 (initially installed in 1987, but could not undergo meaningful plant testing until 1989 because design actuation flow rate was greater than available system test flow rate).
The instrument lines at PNPS have a flow restricting orifice upstream of the EFCVs to limit Reactor water leakage in the event of rupture.
Previous evaluations contained in PNPS's Updated Final Safety Analysis Report (FSAR) of such an instrument line rupture do not credit the EFCVs for isolating the rupture. Thus, a failure of an EFCV, though not expected as a result of this request, is bounded by the analysis. Based on NEDO-32977-A and the analysis contained in PNPS's FSAR, the proposed alternative to the required exercise testing frequency for EFCVs prescribed by OM-10 provides a satisfactory level of quality and safety.
ALTERNATE TESTING:
This Relief Request proposes to exercise open test and exercise close test, by full-stroke to the position required to fulfill its function, a representative sample of EFCVs every refueling outage. During the close test, gross valve seat leakage (LEF) will be measured.
The representative sample is based on approximately 20 percent of the valves (for the case of Dragon EFCVs, one valve) each cycle such that each valve is tested at least once every 10 years. An exercise open test will be performed on each valve following the exercise close test and leak testing.
EFCV failures will be documented in PNPS's Corrective Action Program as a surveillance test failure. The failure will be evaluated and corrected. The Administrative EFCV Sample Test Program procedure will trend EFCV test failure and determine whether additional testing is warranted.
The Administrative EFCV Sample Test Program procedure will also establish minimum acceptance criteria for Dragon EFCVs of less than or equal to 1/2 failure per year (one failure per 2 years) on a 2-year rolling average. This requirement will ensure EFCV performance remains consistent with the extended test interval.
Upon exceeding the criteria, an evaluation will be required which will:
"* require a root cause evaluation to determine cause;
"* determine the extent of conditions;
"* requife an evaluation of the testing interval to ensure reliability of the EFCVs; and
"* produce a risk analysis of the effects of the failures on cumulative and instantaneous plant safety.
Corrective actions and performance goals will be established based on the results of the root cause analysis.

ISTC 4.3.3(a), Frequency. Tests shall be conducted at least once every 2 years.
Leakage rate testing of Category A and AC valves will be performed in accordance with the Performance-Based Testing (PBT) Program in lieu of Subsection ISTC 4.3.3(a), Frequency.
A Performance-Based Testing Program (PBT Program) has been developed which relaxes the prescriptive OM Code seat leakage test frequency requirements and allows test intervals to be based on system service and component performance. Through its own Regulatory Improvement Program, the NRC has instituted an ongoing effort to eliminate requirements that are marginal to safety and to reduce the regulatory burden on utilities. A PBT Program, utilizing an extended testing interval based on the successful completion of two or more consecutive leakage rate tests, would take advantage of the findings of NUREG-1493 Appendix A. The conclusions drawn by the NUREG suggest that "if a component does not fail within two operating cycles, further failures appear to be governed by the random failure rate of the component". The NUREG also states that any test scheme considered should require a failed component to pass at least two consecutive tests before allowing the extended test interval to be applied.
The PBT Program for valves that require seat leakage testing under the OM Code, Subsection ISTC was developed in much the same manner as the Option B Program for Appendix J tested valves, which was permitted by amendment of the Code of Federal Regulations on October 26, 1995. In the studies performed in support of the Code change, it was concluded that performance-based testing is feasible without significant risk (NUREG 1493). Also, EPRI Research Project Report TR-1 04285, "Risk Impact Assessment of Revised Containment Leak Rate Testing Intervals", reaffirmed this position by stating that changes in leakage testing frequencies are feasible without significant risk impact.

The PNPS PBT Program utilizes over a decade of valve seat leakage test data for all the valves (except for the Reactor Vessel Level Reference Leg Backfill Supply Check Valves C2205A & C2206A) included within this program. A test history review was conducted for each valve to determine long-term valve performance and to obtain performance insights that can be used to screen out "suspect valves" that are either more prone to failure or exhibit erratic behavior.
All the valves were then categorized based upon their valve type (i.e.,
check, globe, gate, and ball) and system application to determine which specific valve groups may be more prone to failure. By grouping the valves, a comparison can be performed of similar valves which are in systems with similar service conditions to determine whether some of the valves with good test histories should continue to be monitored more frequently.
Valves that pass a minimum of two consecutive tests exhibit normal operational behavior and have not been flagged as "suspect valves" will be placed on an extended test interval of 4 years or two refueling intervals, whichever is longer. Any valve not meeting the minimum threshold test performance requirement will be left on a 2-year test interval until at least two periodic consecutive acceptable tests have been achieved. In addition, if a failure occurs on any extended interval valve, the initial test frequency of 2 years must be re-established until two consecutive tests are acceptable.

DISCUSSION:
Leakage rate testing of Category A and AC valves will be performed in accordance with the Performance-Based Testing Program. Valves that have met the threshold of passing two periodic consecutive tests will be permitted to be tested every 4 years or two refueling intervals, whichever is longer. Valves which fail their acceptance criterion will return to the 2-year test frequency and must pass a minimum of two consecutive tests before allowing the extended test interval to be reinstated.
The following pages contain the PBT valve groups. The valves included within this Relief Request are categorized by the valve type, system application, and safety function requiring a seat leakage limit. Valves shall meet the applicable guidelines of the Nuclear Energy Institute (NEI-94-01)
Industry Guidelines for Implementing Performance-Based Option of 10CFR Part 50, Appendix J for a performance-based testing program. Using the guidelines, valves that have passed a minimum of two consecutive leakage rate tests may be placed on an extended testing interval. All valves placed on an extended testing interval for seat leakage will still have all other associated ASME OMa Code testing (i.e., exercising and position verification) performed at the required frequency by the Inservice Testing Program. Valves that have not passed the minimum of two consecutive tests will continue to be tested during each refueling interval until their test performance permits an extended testing interval.

Each valve or combination of valves has been assigned an operational frequency rating, which is indicative of the expected frequency that the valve would perform an active function (i.e., opening and closing). The valve operational frequency when combined with system service conditions provides a useful indicator that provides insights related to the expected rate of valve degradation. The assigned operational frequency ratings are defined as follows: Seldom, Infrequent, Occasional, and Frequent.
Seldom - Maintenance or convenience type valves in which operation is seldom desired or required.
Infrequent - Valves in which operation would be expected at a cold shutdown or greater frequency for testing or other evolutions.
Occasional - Valves in which operation would be expected at a quarterly frequency for testing or other evolutions.
Frequent - Valves in which operation is expected during normal plant operation for reasons other than testing. Valves assigned as Frequent will be reviewed for exclusion from the performance-based testing program. If the review shows that normal operation of a specific valve may impair long-term seat leakage reliability, then it will be excluded.
SAFETY RELATED SYSTEM "Q"-LIST/SEISMIC BOUNDARY INTEGRITY Safety related systems that require an active/passive isolation between ASME Code Class and non-Seismic/non-"Q"-List boundary. The isolation ensures that safety-related systems carrying contaminated water postaccident will not leak outside the "Q"-List/Seismic boundary. These valves remain closed during normal plant operation and have their seat leakage limited to a specific maximum amount. Maintaining the seat leakage below a specified limit ensures that system boundary integrity.

Reactor Vessel Level Reference Leg Backfill Supply Check Valves (C2205A &
C2206A Series Pair) provide a makeup flow path from the Control Rod Drive (CRD)
System to each of the Reactor Pressure Vessel level sensing line reference ;ecs This backfill is used to prevent errors in Reactor Vessel level indication during normal and transient operating conditions. The backfill allows makeup flow which prevents the buildup of noncondensable gases. The portion of the CRD System which supplies the makeup flow is non-safety related and the supply check valves must close and limit seat leakage to a specific maximum amount upon loss of the CRD System. Maintaining the seat leakage below the specified limit ensures proper Reactor Vessel level indication and minimizes a potential Reactor coolant leakage path. Seat leakage measurement is currently satisfied by measuring leakage through a downstream telltale connection while maintaining test pressure on one side.
Standby Liquid Control (SLC) Iniection Line - Infrequent:
SLC Inboard Injection Check Valve (CK-1101-15) provides a pressure isolation barrier between the RCS from the high pressure portion of the SLC System.
Normal penetration isolations include an inboard injection valve, an outboard injection valve, and squib valves. Upon firing of the squib valves with the RCS at operating pressure, this check valve becomes one of the two isolation barriers.
Therefore, the valve performs an isolation barrier between the high pressure Reactor system to high pressure safety system interface. Seat leakage measurement is currently satisfied by collecting leakage at the upstream test connection while maintaining test pressure during the Reactor Pressure Vessel leak test.

BASIS FOR RELIEF:
ISTC 4.1, Valve Position Verification. Valves with remote position indicators shall be observed locally at least once every 2 years to verify that valve operation is accurately indicated. Where practicable, this local observation should be supplemented by other indications such as use of flow meters or other suitable instrumentation to verify obturator position. These observations need not be concurrent. Where local observation is not possible, other indications shall be used for verification of valve operation.
Relief is requested from performance of the routinely scheduled position indication verification of at least once every 2 years.
With the institution of 10CFR50.65, Maintenance Rule, plants have ensured that subsequent to work on safety related valves proper postmaintenance testing is performed prior to declaring the valve operable. The postmaintenance testing for valves with remote position indicators ensures that the remote valve position indicators accurately relect valve travel direction. Work activities that would require such a retest are controlled administratively by PNPS postmaintenance guidelines. These strict procedural guidelines over maintenance (both corrective and preventive) activities ensure that proper retests are performed.
Review of PNPS historical test data since 1987 supports the proposed alternate testing in that no position indication failures have been detected during the Code required periodic testing over this period of time. There has been incorrect maintenance performed in which the postmaintenance valve position indication verification test has identified failure.
Correspondence with other utilities has shown that plants with strict procedural controls over their maintenance activities have not experienced failures during routinely scheduled 2-year valve position indication yerifications.

VALVE RELIEF REQUEST VR-04 (CONTINUED)
Industry review has established that the primary means of identifying improper valve position is through system restoration (i.e., returning to normal system operating or standby alignment) following a maintenance outage. Further review has shown that improper valve indication is, except on rare occasion, identified by postmaintenance testing activities, not by routinely scheduled position indication verification tests.
The hardships encountered during the performance of these periodic valve position verifications includes stationing of additional personnel locally (i.e., at the valve) with effective communications to observe valve stroking and performance of special tests when valve position cannot be verified locally. There are subtantial plant resources (Planning and Scheduling, Operations group, Instrumention and Controls group, Programs Test group, Radiation Protection group, and ALARA group) dedicated to the performance of these verifications which require: prejob briefings (e.g., Control Room personnel must be assigned in lieu of other critical tasks), establishing of effective communications (i.e., local and the Control Room), stationing of personnel locally at the valve, and documenting of the verification results. Where the local observation is not possible, other indications are used for the verification of valve operation, such as specialized tests (i.e., seat leakage, system flow, etc.).
Additionally, stationing personnel locally at a valve for observation may require admittance to radiation, high radiation, and possibly locked high radiation areas, thus undermining good ALARA practice.
I The Code position indication requirement is not a test but a simple verification of indicator function. Therefore, position indication is not a parameter that would detect degradation or provide added assurance of valve reliability, but simply verifies valve position. PNPS considers that the proposed alternate testing, and the continuation of current OM Code testing activities, switch-to-light stroke timing and full stroke exercising of active valves, provide adequate assurance that proper valve operation is accurately indicated. In addition, procedural controls for system restoration ensure that plant systems are properly aligned to accomplish their intended function.

ISTC 4.2.8(d): Other power-operated valves with reference stroke times of less than or equal to 10 seconds shall exhibit not more than a +/- 50% nor +/-1 second change in stroke times, whichever is greater, when compared to the reference value.
Relief is requested to use the PNPS Technical Specifications in lieu of the OM Code Subsection ISTC requirements for MSIV stroke timing.
The stroke times of MSIVs are adjusted within an acceptable band of 3 to 5 sconds by adjusting orifices (i.e., needle valve) associated with hydraulic dashpots attached to each operator. Thus, the stroke time performance of each valve operator is more a function of the dashpot setting than the material condition of the valve.
The strict acceptable band of between 3 and 5 (4 +/-1 second) seconds is restrictive enough to ensure that each of the valves remains operable within the established limits of the plant safety analyses. When recording MSIV stroke times to the nearest tenth of a second, the impracticality of meeting the Code becomes apparent when the reference value is between 3.0 and 3.3 seconds. As part of PNPS maintenance practice, efforts are made to set the MSIV hydraulic dashpot to obtain a reference stroke time that is greater than 3.3 seconds. Elimination of the
+/-50 percent limit will have no impact on valve reliability nor on the health and safety of the public.
ALTERNATE TESTING:
The stroke time acceptance criteria for these valves will be determined by the PNPS Technical Specifications, which is between 3 and 5 seconds. Code reference stroke times will not be established nor will the acceptance criteria of ISTC 4.2.8(d) be applied to the test results.

The applicable penetrations and their associated pressure isolation valves have been assigned the highest quality group (Quality Group A) for design, fabrication, testing, and inservice inspection. These design and fabrication requirements minimize the probability of an accidental rupture of the penetration or those lines connected to the penetration. The testing and inservice inspection requirements ensure piping and components maintain their operability and structural integrity throughout the plant's service life. The design configuration (i.e., two valves in series) satisfies the need to protect against a single failure within the RCPB, as it pertains to an intersystem LOCA. If the frequency extension criteria are assigned to each penetration valve pair, the probability of a single failure is greatly reduced.
The PBT Program for PIVs that require seat leakage testing according to the OM Code was developed in much the same manner as the Option B Program for Appendix J tested valves, which was permitted by amendment of the Code of Federal Regulations on October 26, 1995. In the studies performed in support of the Code change, it was concluded that performance-based testing is feasible without significant risk (NUREG 1493). Also, EPRI Research Project Report TR-1 04285, "Risk Impact Assessment of Revised Containment Leak Rate Testing Intervals", reaffirmed this position by stating that changes in leakage testing frequencies are feasible without significant risk impact.
NUREG-1493 did not specifically address the impact on safety where Containment Isolation Valves (CIVs) also serve as PIVs. Regulatory Guide 1.163 endorsed the NEI guidance document but placed limitations on certain valves whose frequencies could not be extended unless the additional risk was considered and appropriately evaluated. The NRC has identified PIVs as fitting this group of valves requiring further risk justification. When evaluating these dual-purpose valves (i.e., CIV/PIV), it was concluded that applying the extension criteria to the PIV penetration, as a valve pair, would lower the risk to an acceptable level of quality and safety. Additionally, each penetration configuration specifies which valve's safety function is for RCPB isolation and/or primary containment isolation. Configurations include:
Configuration No. 1: Inboard Check Valve (PIV), First Motor-Operated Valve (PIV/CIV) and Second Motor-Operated Valve (CIV). The penetration piping and components providing the RCPB isolation function are designed and tested to Quality Group A. The remaining outboard portion, designated for containment isolation, is designed and tested to Quality Group B. The second motor-operated valve (non-PIV) is designed to allow closure at normal Reactor pressure, thereby providing a backup isolation feature.

VALVE RELIEF REQUEST VR-06 (CONTINUED)
Configuration No. 2: Inboard Motor-Operated Valve (PIV/CIV) and Outboard Motor-Operated Valve (PIV/CIV). The penetration piping and components provide RCPB isolation and containment isolation and are designed and tested to Quality Group A. Both of these valves have automatic isolation interlocks which initiate valve closure (and does not allow reopening using electrical power) when Reactor coolant pressure is greater than 70 psig. These valves cannot inadvertently be placed in the open position due to the aforementioned interlocks and the actuator is not designed with sufficient force to overcome the pressure differential across the disk.
Confiquration No. 3: Inboard Feedwater Check (CIV), Inboard HPCI System Check Valve (PIV), and Outboard Motor-Operated Valve (PIV/CIV). The penetration piping and components that provide both RCPB isolation and containment isolation are designed and tested to Quality Group A. These penetrations allow high pressure injection of makeup water into RCS; therefore, the system is designed for high pressures and equipped with additional isolation features.
Each penetration configuration was designed and constructed to withstand the long-term high pressure service associated with the RCS out to the furthermost designated isolation valve from containment. When assessing the risk to a penetration, a degraded PIV(s) could be provided with backup isolation capability, in the case of Configurations 1 and 3, by an additional leak tested isolation valve. These valves are designated as CIVs only,- but are designed to the same pressure/temperature ratings as RCS piping and components, therefore, are capable of performing an RCPB isolation function, if necessary. Existing plant design provides instrumentation to monitor abnormal penetration leakage. Should leakage be detected, closure of this additional high pressure isolation valve, through operator action, would prevent exposing the attached downstream piping and components to an overpressure condition.

The Pressure Isolation Valve PBT Program utilizes over 15 years of valve seat leakage test data. Hydrodynamic leakage testing for valves categorized as PIVs at PNPS began in 1987. Currently, eight satisfactory periodic hydrodynamic leak rate tests, at the maximum function differential pressure (typically 1040 psig), have been completed for each PIV. Of the PIV population at PNPS, only two valves (CK-1001-68B and CK-1301-50) have experienced test failures. A Design Change was implemented in 1999 which addressed the failure of CK-1 001 -68B by installing a swing check to replace the original tilting disk check. The failure mechanism was determined to be improper hinge pin alignment and excessive machining performed during corrective maintenance in 1987. The machining error resulted in the removal of an excessive amount of base material from the valve seating area. The new design has undergone at least two successful periodic leak rate tests performed in 1999 and 2001. CK-1301-50 experienced a seat leakage failure in 1991. The failure mechanism was determined to be a flaw associated with the manual exerciser internal mechanism, whereas a square key was not properly secured in the manual exercising shaft keyway. The detachment of the key and subsequent lodging of the key in the valve internal exerciser resulted in the disk not making full contact with the valve seat. A modification was performed on the shaft keyway to key interface which provided a method to securely attach the key in a more reliable fashion. Since the modification, there have been five successful PIV seat leakage tests.
A review of test history was conducted for each PIV to determine long-term valve performance and to obtain performance insights that can be used to screen out "suspect valves" that are either more prone to failure or exhibit erratic behavior. The valves were then categorized based upon their type (swing check, tilting disk check, and gate) and system application to determine which specific valve groups may be more prone to failure. A comparison was performed of similar PIVs situated in systems with similar service conditions to determine whether certain valves with good test histories should continue to be monitored more frequently.
A PIV pair in a common penetration that passes a minimum of two consecutive tests, exhibits normal operational behavior, and have not been screened out as "suspect valves" will be placed on an extended test interval of 4 years or two refueling intervals, whichever is longer. Any valve pair not meeting the minimum threshold test performance requirement will be left on a 2-year test interval until at least two consecutive acceptable tests have been achieved. In addition, if a failure occurs on any extended interval PIV, the initial test frequency of 2 years shall be re-established for the pair until two consecutive periodic tests are acceptable for both valves. All failures will be evaluated for cause and effect.

Using these guidelines, a penetration valve pair that has passed a minimum of two consecutive leak rate tests may be placed on an extended testing interval. All valves placed on an extended testing interval for seat leakage will continue to receive any other associated OM Code required testing (i.e., exercising, stroke timing and position verification) at the IST Program specified frequencies. A valve pair, in a penetration, that has not passed the minimum of two consecutive tests will require both valves in the penetration to be tested during each refueling outage until their test performance permits an extended testing interval.

REACTOR COOLANT PRESSURE ISOLATION.:
A Pressure Isolation Valve (PIV) pair in a common penetration is defined as two normally closed valves in series that isolate the Reactor6oolarit system (RCS) from an attached low-pressure system. These valves are tested to minimize the probability of an intersystem LOCA and are normally operated (open and close) on an infrequent basis (cold shutdown or refueling outage). The infrequent service that each valve experiences, due to open and close cycling, has no impact on long-term seat leakage reliability.
Maintaining the seat leakage below the specified limit ensures the proper leaktightness of the RCS pressure boundary.
