INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 12 of 304 5.1.2 Regulatory Requirements

1. The Code of Federal Regulations, Title 10, Part 50.55a (10CFR50.55a),

paragraph (f)(5)(i) requires each licensee of pressurized water-cooled nuclear reactors to revise the IST Program to meet the requirements of 10CFR50.55a(f)(4)(ii). As a result, the IST Program must be revised at 120 month intervals to comply with the requirements of the latest edition and addenda of the Code incorporated by reference in 10CFR50.55a(b) 18 months prior to the start of the 120 month interval.

5.1.3 Interval Information

1. The first program interval commenced on November 7, 1977 and ended on March 7, 1981.

2. The second 120-month interval commenced on March 7, 1981 and ended on February 19, 1992.

3. The third 120-month interval commenced on February 19, 1992 and ended on February 18, 2002.

4. The fourth 120-month interval is applicable from February 19, 2002 through and including July 20, 2012.

5. The fifth 120-month interval is applicable from July 21, 2012 through and including February 18, 2023 as stated in correspondence to the NRC:

RA-22-0039. This letter describes Robinsons intent as follows:

• Duke Energy is extending the fifth 10-year 1ST interval end date to February 18, 2023, versus the previously scheduled February 18, 2022, interval end date. Based on this new end date for the fifth 10-year 1ST interval, the sixth 10-year 1ST interval will now begin on February 19, 2023, and end on February 18, 2032.

• The 1ST program plan original pattern end dates for the fifth and sixth 10-year 1ST intervals are February 18, 2022, and February 18, 2032, respectively. Therefore, this adjustment will not cause successive intervals to be altered by more than 1 year from the original pattern.

• The relief requests in Reference 1 have been approved by the NRC for use during the RNP Unit 2 sixth 10-year 1ST interval (References 2, 3, 4, 5, and 6). The date adjustment will not impact the technical details and methodologies in the original relief requests. They will be implemented and used as approved during the sixth 10-year 1ST interval, which now will begin on February 19, 2023, and end on February 18, 2032.

6. The sixth 120-month interval is applicable from February 19, 2023 through and including February 18, 2032.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 13 of 304 5.1.4 Applicable Code

1. In accordance with 10CFR50.55a, the code of record for the IST Program is ASME OM Code - 2017 Edition and subject to limitations and modifications in 10CFR50.55a(b)(3).

5.1.5 Selection of Components

1. Pumps and valves are selected for inclusion in the IST Program based on a review of all plant systems. This review includes UFSAR, Technical Specifications, Administrative and Technical procedures, design documents and Piping & Instrument Diagrams. In accordance with 10CFR50.55a(f), the components subject to OM Code requirements are limited to ASME Class 1, 2, and 3 pumps and valves.

• 10CFR50.55a para. (f)(4) specifies new requirements for augmented components in the IST Program which states: The inservice test requirements for pumps and valves that are within the scope of the ASME OM Code but are not classified as ASME BPV Code Class 1, Class 2, or Class 3 may be satisfied as an augmented IST program in accordance with paragraph (f)(6)(ii) without requesting relief under paragraph (f)(5) or alternatives under paragraph (z). This use of an augmented IST program may be acceptable provided the basis for deviations from the ASME OM Code, as incorporated by reference, demonstrates and acceptable level of quality and safety. or that implementing the Code provisions would result in hardship or unusual difficulty without a compensating increase in the level of quality or safety, where documented and available for NRC review.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 14 of 304 5.1.5 Selection of Components (continued)

2. Components and tests that are required by 10CFR included in this IST Program Plan are identified as follows:

• Components optionally classified as Code Class 3 (e.g., Diesel Fuel Oil system) are identified in Attachment 5, Pump Table, or Attachment 7, Valve Table.

• Valves not within the Code Class 1, 2, or 3 boundaries are identified in Attachment 7, Valve Table, with an Aug- in front of the valve category letter designation (A, B, C, etc).

• For pumps and valves that are within the scope of the ASME OM Code but are not ASME BPV Code Class 1, 2, or 3 components, the use of an augmented IST program is acceptable without prior NRC approval [i.e.,

without relief under § 50.55a(f)(5) or an alternative under § 50.55a(z)].

This is provided the basis for deviations from the ASME OM Code demonstrates an acceptable level of quality and safety, or that implementing the Code provisions would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety.

5.1.6 Code Classification

1. Code classification of pumps and valves at RNP is described in UFSAR Section 3.9.6 and is shown on the Piping and Instrumentation Diagrams provided in following section.

5.1.7 Systems and Flow Diagrams

1. A list of systems included in the IST Program along with the associated Piping and Instrumentation Diagrams (P&IDs) that identify the Code boundaries is provided in Attachment 1, Systems and P&IDs.

5.1.8 Relief Requests

1. Specific requests for relief in accordance with 10CFR50.55a(a)(3) pursuant to NUREG-1482, Revision 3, Guidelines for Inservice Testing at Nuclear Power Plants, are provided in Attachment 2, Relief Requests. Where conformance with the requirements of the Code have been determined to be impracticable, alternate testing is proposed that would provide an acceptable level of quality and safety. Where conformance with the requirements of the Code would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety, alternate testing is proposed that would provide useful information to assess the operational readiness of the component tested.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 15 of 304 5.1.8 Relief Requests (continued)

2. The relief requests define the component(s) and test(s) involved the basis for relief and the proposed alternative testing.

3. Relief requests approved by the NRC shall not be altered without prior notification and approval by the NRC. The modification need not be in the form of a relief request; however, correspondence and acceptance by the NRC is required prior to implementing the revised request.

4. Relief requests are numbered in an IST-RR-N format where:

IST = Designates relief request applicability to the IST Program Plan RR = Relief request N = Unique sequential number 5.1.9 Use of Later Editions and Addenda (NRC Regulatory Issue Summary 2004-12)

1. Later editions or addenda of the OM Code, incorporated by reference in paragraph (b) of 10CFR50.55a may be implemented during the course of an inspection interval subject to the limitations and modifications listed in paragraph (b) of 10CFR50.55a and provided all related requirements of the respective Code edition or addenda have been met. The voluntary update to a later Code edition or addenda of the Code referenced in paragraph (b) is not considered a relief request. Therefore, the requirements are not as stringent. A letter must be submitted to the NRC and should include a discussion of the related requirements. NRC approval is required prior to implementation. RIS 2004-12 provides clarification related to the process by which NRC approval can be obtained.

5.1.10 ASME Code Case Applicability

1. The NRC staff has developed RG 1.192, Operation and Maintenance Code Case Acceptability, ASME OM Code, and RG 1.193, ASME Code Cases Not Approved for Use.

2. Per Revision 3 of NUREG-1482, the licensee may implement the Code Cases listed in RG 1.192 without obtaining further NRC review, if the Code Cases are used in their entirety, with any supplemental conditions specified in the regulatory guide (RG). RG 1.192 also lists Code Cases that are conditionally acceptable.

3. Code Cases that may be utilized by the Inservice Test Program are listed below:

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 16 of 304 5.1.10 ASME Code Case Applicability (continued)

a. Code Case OMN-18, Alternate Testing Requirements for Pumps Tested Quarterly Within +/-20% of Design Flow, is implemented at RNP to facilitate not performing the Comprehensive Test with the associated acceptance criteria, if the quarterly test is performed at the flow rate and with the instrumentation required for the comprehensive test. This code case has been approved for use by the NRC with no conditions as referenced in RG 1.192, Operation and Maintenance Code Case Acceptability, Table 1, Acceptable OM Code Cases.

• This code case allows a Group A test be performed quarterly within

+/-20% of pump design flow rate, with instrumentation meeting the requirements of Table ISTB-3510-1 for the Comprehensive and Preservice Tests, eliminating the requirement for a comprehensive test.

• RNP will apply this code case to the following pumps:

CCW-A, CCW-B, CCW-C 5.1.11 Test Deferral Justifications

1. In accordance with Section 5.3.12 and Section 5.3.27 Step 2, certain valves are full stroke exercised during cold shutdown conditions when they cannot be exercised during normal operation. When a valve cannot be exercised during normal operation or cold shutdown conditions, then it is full stroke exercised during refueling outages. The technical justification for exercising a valve during cold shutdown or refueling outages rather than normal operation is provided in a Cold Shutdown Test Justification or Refueling Outage Test Justification.

Information is contained in Attachment 3, Cold Shutdown Justifications, and Attachment 4, Refueling Shutdown Justifications.

2. Augmented valves will be tested in accordance with the requirements of ISTC, and all associated Appendices. Each Non Code component that is tested using an Alternative Testing Methodology or Frequency is addressed in a Technical Position that explains the alternative method and why it is accepted. Any alternative testing will be identified by Technical Positions, and is contained in Attachment 9, Technical Position.

3. Valves tested during cold shutdowns or refueling outages shall be scheduled in accordance with Section 5.3.12 and Section 5.3.27 Step 2.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 17 of 304 5.1.11 Test Deferral Justifications (continued)

4. Cold Shutdown Test Justifications and Refueling Outage Test Justifications are numbered in a XXX-VCS-N or XXX-VRS-N format where:

XXX = System Acronym VCS = Cold Shutdown Test Justifications VRS = Refuel Outage Justifications N = Unique sequential number

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 18 of 304 5.1.12 Test Frequency Grace

1. Components whose test frequencies are based on elapsed time periods shall be tested at the frequencies specified in Section IST with a specified time period between tests as shown in Table 1, Specified Test Frequencies. The specified time period between tests may be reduced or extended as follows:

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

• For periods greater than or equal to 2 years, period may be extended by up to 6 months.

• Period extensions may be applied to accelerated test frequencies (e.g.,

pumps in alert range).

• Period extensions may be applied to other test frequencies not specified in Table 1, Specified Test Frequencies, provided the frequency is less than 2 years.

• Period extensions may not be applied to the test frequency requirements specified in Subsection ISTD, Preservice and Inservice Examination and Testing of Dynamic Restraints (Snubbers).

• All periods specified may be reduced at the discretion of RNP (i.e., there is no minimum period requirement).

• Components whose test frequencies are based on plant conditions or events (e.g., cold shutdown, refueling, maintenance, etc.) may not have their period between tests extended except as allowed by Table 1, Specified Test Frequencies.

Table 1, Specified Test Frequencies Frequency Specified Time Period Between Tests Quarterly (every 3 months) 92 days Semiannually (every 6 months) 184 days Annually (every year) 366 days

2. Period extensions are not intended to be used repeatedly as an operational convenience.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 19 of 304 5.1.13 Preconditioning (NRC Information Notice 97-16)

1. NRC IN 97-16 has been evaluated for applicability and corrective measures have been taken to address preconditioning concerns involving IST activities.

Preconditioning may be defined as the alteration, variation, manipulation or adjustment of the physical condition of an SSC before Technical Specification surveillance or ASME Code testing. In some cases, the safety benefit of a preconditioning activity may outweigh the benefits of testing in the as-found condition. In the event that this condition arises, the activity should be evaluated to determine whether it constitutes acceptable or unacceptable preconditioning.

The overall effect of the activity and a justification documenting the continued confidence in the capability to assess the operational readiness of the component must be considered in order to determine whether the activity constitutes acceptable pre-conditioning.

2. NRC Inspection Manual, Part 9900 should be consulted for additional guidance to assist in determining whether a certain activity should be considered to be preconditioning. It may also be used to provide further guidance as to the acceptability or unacceptability of the preconditioning event. Unacceptable preconditioning is to be avoided. The following are examples of acceptable and unacceptable preconditioning.

Acceptable preconditioning Robinson considers several factors in determining whether an activity constitutes acceptable preconditioning of a pump or valve to be tested. For example, an activity would constitute acceptable preconditioning of a pump or valve if it is performed to protect personnel or equipment, or to meet the manufacturers recommendations (or based on industry-wide operating experience). If a preventive maintenance activity (such as valve stem lubrication or pump venting) periodically occurs prior to testing, Robinson might justify the acceptability of this infrequent preconditioning of a pump or valve if it the effect of the activity on the overall ability to assess the operational readiness of the pump or valve is evaluated, and the ability to trend degradation in its performance isnt impacted.

As noted in the NRC inspection guidance, Robinson should evaluate and document the activity as acceptable preconditioning before performing the testing. Additional examples include:

• Pump venting prior to testing provided that the venting operation has proper controls with a technical evaluation to establish that the amount of gas vented would not adversely affect pump operation.

• Draining turbine steam supply lines prior to surveillance testing provided that evolution has proper controls

• Occasional lubrication of a valve stem prior to testing a valve, where stem lubrication is not typically performed prior to testing.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 20 of 304 5.1.13 Preconditioning (NRC Information Notice 97-16) (continued)

• Unavoidable movement attributable to the setup and connection of test equipment.

• Improper timing of a power operated valve where the valve must be immediately retested in order to obtain a valid stroke time measurement.

Adequate assurance must be available to support the conclusion that the valve stroke time would have been below the limiting value. The deviation shall be documented in the record of test.

Unacceptable preconditioning Some activities would constitute unacceptable preconditioning of a pump or valve to be tested under the IST program. NRC Manual Chapter 9900 (Technical Guidance: Maintenance) defines unacceptable preconditioning of an SSC as an activity before or during surveillance or testing that alters one or more of the SSCs operational parameters which results in acceptable test results. For example, a preventive maintenance activity might constitute unacceptable preconditioning of a pump or valve if the licensee routinely conducts the activity prior to testing. NRC Inspection Manual, IP 71111, Attachment 22, instructs NRC inspectors to evaluate the acceptability of any preconditioning of equipment in preparation for surveillance tests. Similarly, NRC inspectors also verify that licensees do not routinely schedule preventive maintenance activities prior to testing in order to help ensure that the test is passed satisfactorily. In addition to activities related to an individual pump or valve, maintenance or surveillance activities involving several SSCs, including the scheduling or timing of such activities, can inadvertently result in unacceptable preconditioning of a pump or valve.

NRC Manual Chapter 9900 (Technical Guidance: Maintenance) provides a series of questions that NRC inspectors should consider when evaluating the acceptability of an activity that appears to involve preconditioning of a plant SSC.

With respect to pumps and valves, those questions can be interpreted as follows:

• Does the practice performed ensure that the pump or valve will meet its testing acceptance criteria?

• Would the pump or valve have failed the test without the preconditioning?

• Does the practice bypass or mask the as-found condition of the pump or valve?

• Is preventive maintenance routinely performed on the pump or valve just before testing?

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 21 of 304 5.1.13 Preconditioning (NRC Information Notice 97-16) (continued)

• Is preventive maintenance on the pump or valve performed only for scheduling convenience?

Examples of unacceptable preconditioning include:

• Routine lubrication of a valve stem prior to testing the valve.

• Operation of a pump or valve shortly before a test, if such operation could be avoided through plant procedures with personnel and plant safety maintained.

• Venting a pump immediately prior to testing without proper controls and scheduling.

• An activity performed to ensure that the pump or valve will meet its acceptance criteria.

• An activity performed to mask the as-found condition of the pump or valve.

AD-EG-ALL-1450, Preconditioning of Structures, Systems, and Components, provides more detail.

5.1.14 Use of Non-conservative Acceptance Criteria (NRC information Notice 97-090)

1. Information regarding the minimum performance requirements for each pump tested to ASME Code requirements may be found in calculation RNP-M/MECH-1802, Safety Related Pump Minimum Performance Requirements. All surveillance test acceptance criteria are reviewed to ensure that minimum performance requirements are met.

2. Design engineering establishes the minimum allowable pump performance requirements based on instrument uncertainties and EDG frequency and voltage variations. The resultant criteria is included in the appropriate pump performance tests used to confirm design basis requirements. [7.3.31]

5.1.15 Program Notebook

1. A program notebook will be developed and maintained by IST personnel consistent with the guidelines established in AD-EG-ALL-1600, Engineering Programs.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 22 of 304 5.1.16 Basis Document

1. A basis document is maintained in the electronic IST database. This data should be used for information only. The IST database is a tool intended to assist the user in understanding the rationale for testing or excluding certain pumps or valves from the IST program and shall not be used to verify design or licensing basis.

5.1.17 Inservice Testing Evaluation

1. Establishment of new reference values for pump and valves should be completed using the IST Reference Value Change / Rebaseline attachment in AD-EG-ALL-1720, Inservice Testing (IST) Program Implementation. This common process may be used to evaluate component performance, establish new reference values, and corresponding acceptance criteria.

2. The determination of acceptance limits is based on multiplication tables provided in the ASME OM Code, unless truncated by a design document. The derivation of acceptance limits involves simple arithmetic and is not considered to be a calculation. These new limits shall be peer checked by the system or responsible engineer.

3. Component performance evaluations shall follow all requirements of the Code; however, minimum fundamental elements must be addressed when completing the evaluation.

• Is the cause of the deviation known and the impact understood?

• Are the proposed acceptance limits within design basis performance requirements? Generally, pump performance must achieve a minimum hydraulic point and power operated valves must stroke below a specified limiting value.

• For changes to pump vibration reference values, does the Vibration Engineer concur with the proposed alert and required action limits?

• Established processes shall be used to ensure that the impacted procedure has been identified and is placed on hold, if changes to acceptance limits are required.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 23 of 304 5.1.17 Inservice Testing Evaluation (continued)

4. Caution should be exercised if an evaluation is used to recommend pump operability when performance is in the alert or required action range. Consult guidance in AD-OP-ALL-0105, Operability Determinations, to review additional actions related to deficient conditions.

• In addition, for pump performance in the alert or required action range, and continued performance at this range is supported by an analysis, a pump and system level evaluation of operational readiness must be performed by the applicable System Engineer.

17. Trending Test parameters shown in Table 2, except for fixed values shall be trended.

18. Acceptance Criteria

a. Alert Range - If the measured test parameters values fall within the alert range of Table 4, Table 5, or Table 7 as applicable, the frequency of testing specified in Section 5.2.11 Step 7 shall be doubled until the cause of the deviation is determined and the condition is corrected.

b. Action Range - If the measured test parameter values fall within the required action range of Table 4, Table 5, Table 6, or Table 7, as applicable, the pump shall be declared inoperable until the cause of the deviation is determined and the condition is corrected, or an analysis of the pump is performed and a new reference values are established in accordance with Section 5.2.10.

c. Systematic Error - When a test shows measured parameter values that fall outside of the acceptance range of Table 4, Table 5, Table 6, or Table 7, as applicable, and have resulted from an identified systematic error such as improper system lineup or inaccurate system instrumentation, the test shall be rerun after correcting the error.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 43 of 304 5.3.3 Valve Categories

1. Valves shall be placed in one or more of the following categories. When more than one distinguishing category characteristic is applicable, all requirements of each of the individual categories are applicable, although duplication or repetition of common testing requirements is not necessary.

• Category A - Valves for which seat leakage is limited to a specific maximum amount in the closed position for fulfillment of their required function.

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

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

• Category D - Valves that are actuated by an energy source capable of only one operation, such as rupture disks or explosively actuated valves.

2. In addition to the valve categories described above, valves are also characterized as active or passive based on the definitions below.

• Active Valves - Valves that are required to change obturator position to accomplish their required function.

• Passive Valves - Valves that maintain obturator position and are not required to change obturator position to accomplish their required function.

5.3.4 Preservice Testing

1. Each valve shall be tested during the preservice period. These tests shall be conducted under conditions as near as practicable to those expected during subsequent inservice testing. Note that the Preservice Period had already passed when IST requirements were first introduced at Robinson. Only one preservice test of each valve is required with the following exceptions:

• Any valve that has undergone maintenance that could affect its performance after the preservice test shall be tested in accordance with Section 5.3.7;

• Safety and relief valves and non-reclosing pressure relief devices shall meet the preservice test requirements of Appendix I of the OM Code.

• Active motor-operated valves (MOV) shall meet the preservice test requirements of Mandatory Appendix III.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 44 of 304 5.3.5 Inservice Testing

1. Inservice testing shall commence when the valves are required to be operable to fulfill their required function(s).

5.3.6 Reference Values

1. Reference values shall be determined from the results of preservice testing or from the results of inservice testing. These tests shall be performed under conditions as near as practicable to those expected during subsequent inservice testing.

2. Values shall be established only when the valve is known to be operating acceptably. If the particular parameter being measured can be significantly influenced by other related conditions, then these conditions shall be analyzed.

5.3.7 Effect of Valve Maintenance, Replacement, or Repair

1. When a valve or its control system has been replaced, repaired, or has undergone maintenance that could affect the valves performance, a new reference value shall be determined or the previous value shall be reconfirmed by an inservice test before it is returned to service. Deviations between the previous and new reference values shall be identified and analyzed. Verification that the new values represent acceptable operation shall be documented in the record of tests.

2. Safety and relief valves and non-reclosing pressure relief devices shall be tested as required by the replacement, repair and maintenance requirements of EST-027, Pressurizer Safety Valve Testing, EST-028, Main Steam Safety Valve Testing, EST-068, Testing Spray Additive Tank Breakers, EST 112, Pressure, Safety, and Relief Valve Bench Testing, and EST-130, Testing CC-948, CCW Surge Tank Vacuum Breaker. These ESTs meet the requirements of OM Code, Appendix I 5.3.8 Establishment of Additional Set of Reference Values

1. If it is necessary or desirable for some reason, other than the requirements of Section 5.3.7, to establish additional reference values, an inservice test shall first be run at the conditions of an existing set of reference values, or, if impractical, at the conditions for which the new reference values are required, and the results analyzed.

2. If operation is acceptable in accordance with Section 5.3.7, a second test shall be performed under the new conditions as soon as practicable.

3. The results of the second test shall establish the additional reference values.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 45 of 304 5.3.8 Establishment of Additional Set of Reference Values (continued)

4. The reasons for establishing additional reference values shall be justified and documented in plant records.

5.3.9 Inservice Testing Requirements

1. Active and passive Category A, B, C, and D valves shall be tested in accordance with Table 8.

a. There are no ASME Code class Category D (explosive valves, rupture discs) at RNP.

5.3.10 Testing Methods

1. Testing methods are clearly defined within the implementing procedures.

5.3.11 Valve Position Verification

1. Valves with remote position indicators shall be observed locally at least once every 2 years to verify that valve operation is accurately indicated.

2. Position verification for active MOVs shall be tested in accordance with Mandatory Appendix III.

3. 10 CFR 50.55a para. (b)(3)(xi) Condition requires obturator verification with definitive verification of obturator integrity e.g., stem-to-disc verification using other positive means. The supplemental valve position verification requirement in

§ 50.55a(b)(3)(xi) (OVO/OVC) is not a separate test from the valve position verification requirement in ISTC-3700. The purpose of observing such parameters as flow is to provide reasonable assurance that the indicating lights are accurately monitoring the valve obturator position. Therefore, the lights and supplemental observations need to be monitored together to demonstrate that the lights are performing properly. The OVO and OVC verifications are not required to be performed concurrently, but are required within the same periodicity. Also, the implementation of this Condition is a running or continuous frequency interval much like that of RVs. In other words, on day 1 of a new Interval start, if an RPI is due so is the supplemental obturator verification.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 46 of 304 5.3.12 Category A and B Valve Exercise Tests

1. Exercising Test Frequency

a. Active Category A and B valves shall be tested nominally every 3 months, except as provided by Section 5.3.12, Section 5.3.17 and Section 5.3.18.

2. Exercising Requirements

a. Valves shall be tested as follows:

• Full stroke exercising during plant operation to the position required to fulfill its function;

• If full-stroke exercising during plant operation is not practicable, it may be limited to part-stroke exercising during plant operation and full-stroke exercising during cold shutdown;

• If exercising is not practicable during plant operation, it may be limited to full stroke exercising during cold shutdown;

• If exercising is not practicable during plant operation and full-stroke during cold shutdowns is also not practicable, it may be limited to part stroke during cold shutdowns, and full-stroke during refueling outages;

• If exercising is not possible during plant operations or cold shutdowns, it may be limited to full stroke exercising during refueling outages;

• Except as specified below, valves full-stroke exercised during cold shutdowns shall be exercised during each cold shutdown.

Exercising is not required if the time period since the pervious full-stroke exercise is less than 3 months.

• Valve exercising during cold shutdown shall commence within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of achieving cold shutdown and continue until all testing is completed or the plant is ready to return to power. For extended outages, testing need not be commenced in 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> provided all valves required to be tested during cold shutdowns will be tested prior to plant startup and all valves that are required to perform their specified function are exercised every 3 months. However, it is not intended to keep the plant in cold shutdown to complete cold shutdown testing.

• All valve testing required to be performed during a refueling outage shall be completed before returning the plant to operation.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 47 of 304 5.3.13 Valve Obturator Movement

1. The necessary valve obturator movement shall be determined by exercising the valve while observing an appropriate indicator, such as indicating lights or observing other evidence such as changes in system pressure, flow rate, level, or temperature.

5.3.14 Pneumatically-Operated Valves

1. Active AOVs shall meet the requirements of Mandatory Appendix IV of this Division.

5.3.15 Motor-Operated Valves

1. Active MOVs shall meet the requirements of Mandatory Appendix III of this Division.

5.3.16 Power-Operated Valve Stroke Testing

1. Limiting values of full-stroke time of each power-operated valve shall be specified.

2. The stroke time shall be measured to at least the nearest second.

3. Any abnormality or erratic action shall be recorded and an evaluation shall be made to determine if corrective action is required.

5.3.17 Power-Operated Control Valve Testing

1. For power-operated control valves that have only a fail-safe safety function, the requirements for valve stoke-time testing, the associated stroke-time test acceptance criteria, and any corrective actions that would result from stroke-time testing need not be met. For these valves, all other applicable requirements listed below shall be met.

• Valve Exercise Testing

• Position Indication Testing

• Leakage Testing

• Any abnormality or erratic action shall be recorded and an evaluation shall be made regarding the need for corrective action.

2. Valves with fail-safe actuators shall be tested by observing the operation of the actuator upon loss of valve actuator power. Note that there are valves with fail-safe actuators where neither the actuator nor the valve has a safety function.

These actuators are not included in the program.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 48 of 304 5.3.18 Power-Operated Relief Valve Testing

1. Power-operated relief valves testing shall be performed in the following sequence or concurrently. If testing in the following sequence is impractical, it may be performed out of sequence, and a justification shall be documented in the record of tests for each test or in the test plan. Pursuant to this requirement, leakage testing of PORVs is performed on a continuous basis using installed plant indicators and daily RCS leak rate computations. These tests are performed at normal operating pressure and exceed the test pressures required by Appendix I of the OM Code for seat tightness testing. Therefore, an additional seat leakage test is not necessary. This observation will be documented in EST-152, Engineering Periodic Verification of IST Components.

RNP power-operated relief valves are not capacity certified.

The following test requirements apply to power-operated relief valves:

• Leakage testing

• Stroke testing, including stroke time

• Position Indication Testing

• Any abnormality or erratic action shall be recorded and an evaluation shall be made regarding the need for corrective action

• Stroke testing shall be performed during normal operating conditions for temperature and pressure 5.3.19 Valves in Regular Use

1. Valves that operate in the course of plant operation at a frequency that satisfies the exercising requirements need not be additionally exercised, provided that the observations otherwise required for testing are made and analyzed during operation. The results shall be recorded in the plant record at intervals no greater than specified in Section 5.3.12.

5.3.20 Valves in systems Out of Service

1. For valves in a system declared inoperable or not required to be operable, the exercising test schedule need not be followed. Valves shall be exercised within 3 months before placing the system in operable status and the normal test frequency resumed.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 49 of 304 5.3.21 Power Operated Valves Stroke Time Acceptance Criteria

1. Test results shall be compared to the initial reference values or reference values established in accordance with Section 5.3.7 or Section 5.3.8.

b. Pneumatic, Hydraulic, Solenoid and Power-operated relief valves with reference stroke times of less than or equal to 10 seconds shall exhibit no more than +/-50% change in stroke time when compared to the reference value.

c. Power operated valves that stroke in less than 2 seconds may be exempted from Step 1.a and Step 1.b above. In such cases the maximum stroke time shall be 2 seconds.

d. Active motor-operated valves that have stroke time specified in plant technical specifications which satisfy the assumptions in the plant's safety analyses shall be verified [10CFR50.55(b)(ii)(D) Condition]. This verification is considered a go-no-go test with no acceptance criteria or reference value.

5.3.22 Corrective Action for Stroke-Timed Valves

1. If a valve fails to exhibit the required change of obturator position or exceeds the limiting values of full-stroke time of Section 5.3.21 Step 1, the valve shall be immediately declared inoperable.

2. Valves with measured stroke times that do not meet the acceptance criteria of Section 5.3.21, shall be immediately retested or declared inoperable. If the valve is retested and the second set of data also does not meet the acceptance criteria, 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 documented in the record of tests.

3. Valves declared inoperable shall 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. Valve operability based upon analysis shall have the results recorded in the record of tests. Caution should be exercised if an evaluation is used to recommend valve operability when performance is in the alert or required action range. Consult guidance in AD-OP-ALL-0105, Operability Determinations, to review additional actions related to deficient conditions.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 50 of 304 5.3.22 Corrective Action for Stroke-Timed Valves (continued)

5. Before returning a repaired or replaced valve to service, a test demonstrating satisfactory operation shall be performed.

5.3.23 Seat Leakage Tests for Category A Valves

1. Scope Category A valves shall be leakage tested, except that valves which function in the course of plant operation in a manner that demonstrates functionally adequate seat leak tightness need not be additionally tested. In such cases, the valve record shall provide the basis for the conclusion that operational observations constitute satisfactory demonstration.

2. Containment Isolation Valves

• Containment isolation valves with a leakage rate requirement based on an Appendix J program shall be tested in accordance with TMM-005, 10CFR50, Appendix "J" Testing Program. Procedure TMM-005 meets the requirements of 10CFR50, Appendix J.

• Containment isolation valves with a leakage requirement based on other functions shall be tested in accordance with Section 5.3.23 Step 4.

3. Leakage Rate for other than Containment Isolation Valves

a. These valves shall be leakage tested to verify their leak-tight integrity.

Valve closure before seat leakage testing shall be by using the valve operator with no additional closing force applied.

4. Frequency - Containment Isolation Valves with a leakage rate requirement shall be tested at the frequency specified in TMM-005. All valves requiring leak tests based on other functions shall be conducted at least once every 2 years.

5. Differential Test Pressure - Differential pressure shall be applied in the same direction as when the valve is performing its function with the following exceptions:

• Globe valves may be tested with the pressure under the seat,

• Butterfly valves may be tested in either direction, provided their seat construction is designed for sealing against pressure on either side.

• Double-disk gate valves may be tested by pressurizing between the seats,

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 51 of 304 5.3.23 Seat Leakage Tests for Category A Valves (continued)

• Seat leakage tests involving pressure differential lower than function pressure differentials are permitted in those valves in which service pressure will tend to diminish the overall leakage channel opening,

• Valves that do not qualify for reduced pressure testing shall be tested at maximum function pressure.

6. Seat Leakage Measurement - Valve Seat leakage shall be determined by one of the following methods:

• Measuring leakage through a downstream telltale connection while maintaining pressure on one side of the valve.

• Maintaining feed rate required to maintain test pressure in the test volume or between two seats of a gate valve, provided the total apparent leakage rate is charged to the valve or valve combination.

• Determining leakage by measuring pressure decay in the test volume.

7. Test Medium - shall be specified in the procedure.

8. Analysis of Leakage Rates - Leakage rate measurements shall be compared with the permissible leakage rates specified by the Owner (usually identified in the implementing test procedure). The permissible leakage rate specified by the Owner should be based on specific design or operational criteria limits. When this criteria cannot be determined, then the permissible leak rate may be calculated as follows:

• For water, 0.5D gal/min or 5 gal/min, whichever is less, at functional differential pressure, where D equals nominal valve size.

• For air, 7.5D standard ft3/day, at functional differential pressure.

9. Corrective Action - Valves or valve combinations with leakage rates exceeding the values specified by the Owner in Step 8 shall be declared inoperable and either repaired or replaced. A retest demonstrating acceptable operation shall be performed following any required corrective action before the valve is returned to service.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 52 of 304 5.3.24 Tests for Category C Safety and Relief Valves

1. Tests for Category C Safety and Relief Valves are conducted in accordance with Appendix I of the OM Code.

d. Containment Spray Additive Tank Vacuum Breakers are tested in accordance with EST-068, Testing Spray Additive Tank Breakers.

e. The CCW Surge Tank Vacuum Breaker is tested in accordance with EST-130, Testing CC-948, CCW Surge Tank Vacuum Breaker.

f. The performance of the individual valve tests is governed by the work order process and procedures EST-027, Pressurizer Safety Valve Testing, EST-028, Main Steam Safety Valve Testing, EST-068, Testing Spray Additive Tank Breakers, EST-112, Pressure, Safety, and Relief Valve Bench Testing, and EST-130, Testing CC-948, CCW Surge Tank Vacuum Breaker. The work orders are utilized to periodically verify that test frequencies applicable to safety valves, relief valves and vacuum breakers conform to the frequency requirements specified in Appendix I of the OM Code.

5.3.25 Appendix III

1. Appendix III establishes the requirements for preservice and inservice testing to assess the operational readiness of active motor-operated valves (MOVs). It basically 'codifies' the legacy GL 89-10 MOV Programs. It eliminates stroke time testing except for that population of MOVs subject to the NRC Condition.

• In some cases, there are new additions to the scope due to mismatches between Active IST Program valves and that of the legacy GL 89-10 Program

• Appendix III refers to only high and low risk categories

• Exercising requirements are relaxed for low risk MOVs and in many cases, deferred test justifications are no longer required

• Documentation requirements may require more focus

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 53 of 304 5.3.26 Appendix IV

1. Appendix IV establishes the requirements for preservice and inservice testing to assess the operational readiness of active motor-operated valves (AOVs). It basically 'codifies' the AOV JOG Programs.

• In some cases, there are new additions to the scope due to mismatches between Active IST Program valves and that of the legacy AOV JOG Program

• Appendix IV refers to only high and low risk categories

• For low risk AOVs, the requirements basically remain the same

• Documentation requirements may require more focus 5.3.27 Exercise Tests for Category C Check Valves

1. Exercising Test Frequency Check valves shall be exercised nominally every 3 months except as provided in Section 5.3.27 Step 2.a(2) through Section 5.3.27 Step 2.a(6).

2. Exercising Requirements

a. Valves shall be exercised as follows:

(1) During plant operation, valves shall be exercised or examined in a manner that verifies obturator travel by using the methods in Section 5.3.27 Step 4.

(2) Each check valve exercise test shall include open and close tests.

Open and close tests need only be performed at an interval when it is practical to perform both tests. Open and close tests are not required to be performed at the same time if they are both performed within the same interval.

(3) If exercising is not practicable during plant operation, it shall be performed during cold shutdowns.

(4) If exercising is not practicable during plant operation and cold shutdown, it shall be performed during refueling outages.

(5) Valves exercised at shutdowns shall be exercised during each shutdown, except as specified in 6 below. Such exercise is not required if the interval since the previous exercise is less than 3 months.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 54 of 304 5.3.27 Exercise Tests for Category C Check Valves (continued)

(6) Valve exercising shall commence within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of achieving cold shutdown and continue until all testing is complete or the plant is ready to return to power. For extended outages, testing need not be commenced in 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> if all the valves required to be tested during cold shutdown will be tested before plant startup. However it is not the intent to keep the plant in cold shutdown to complete cold shutdown testing.

(7) All valve testing required to be performed during refueling outages shall be completed before returning the plant to operation.

3. Valves in Regular Use

a. Check valves that operate in the course of plant operation, at a frequency that would satisfy the exercising requirements, need not be additionally exercised. The observations otherwise required for testing are required to be made, analyzed, and recorded in the plant records at intervals not greater than 3 months.

4. Valve Obturator Movement

a. The necessary valve obturator movement shall be demonstrated by performing both an open and a closed test.

• Check valves that have a safety function in both the open and closed directions shall be exercised by initiating flow and observing that the obturator traveled to either the full open position, or to the position required to perform its intended function. Verification that on cessation of flow the obturator has traveled to its seat shall also be demonstrated.

• Check valves that have a safety function in only the open direction shall be exercised by initiating flow and observing that the obturator has traveled to either the full open position or to the position required to perform its intended function and verify closure.

• Check valves that have a safety function in only the closed direction shall be exercised by initiating flow and observing that the obturator has traveled to at least the partially open position, and verify that on cessation or reverse flow, the obturator has traveled to its seat.

b. Observations shall be made by observing a direct indicator or by other positive means such as change in system pressure, flow rate, level, temperature, seat leakage testing, or non-intrusive testing.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 55 of 304 5.3.27 Exercise Tests for Category C Check Valves (continued)

c. If the test methods described in Section 5.3.27 Step 4.a are impractical for certain check valves, or if sufficient flow cannot be achieved or verified, a sample disassembly examination program shall be used to verify valve obturator movement.

• The sample disassembly program shall group valves of similar design, application, and service condition and require a periodic examination of one valve from each group. The details and bases for the sampling program shall be documented.

• Grouping of check valves shall be technically justified and shall consider valve manufacturer, design, service, size, materials of construction, and orientation

• During the disassembly process, the full-stroke motion of the obturator shall be verified. Valves that have been disturbed prior to verifying obturator movement shall be examined to determine if a condition exists that could prevent full opening or reclosing of the obturator.

• At least one valve from each group shall be disassembled and examined at each refueling outage. All valves in each group shall be disassembled and inspected once every 8 years.

• Before return to service, valves that were disassembled for examination or that received maintenance that could affect their performance shall be exercised if practicable with flow in accordance with Section 5.3.27 Step 4.

These valves shall also be tested for other requirements such as leak rate testing.

Examples of check valves that can be impacted by disassembly include spring loaded check valves or check valves with the obturator supported by the bonnet.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 56 of 304 5.3.27 Exercise Tests for Category C Check Valves (continued)

5. Check Valve Condition Monitoring

a. As an alternative to the testing or examination requirements of Section 5.3.27 Step 1 through Section 5.3.27 Step 4, a Check Valve Condition Monitoring Program may be established. The purpose of this program is both to improve valve performance and to optimize testing, examination, and preventative maintenance activities in order to maintain the continued acceptable performance of a select group of check valves.

(1) The Check Valve Condition Monitoring Program may be implemented on a valve or group of similar valves.

(2) The Check Valve Condition Monitoring Program is implemented in accordance with TMM-008, Check Valve Program Technical Requirements.

• Each valve must be tested to both the open and closed direction (bi-directional test).

• The maximum test or examination interval for a valve or group of valves is based on the following table. All valves in the group must be tested or examined within the maximum interval to be considered a valid extension.

• The interval between activities shall not exceed intervals imposed by other station programs where activities are credited for meeting the requirements of condition monitoring (e.g., Containment Leakage Rate Testing Program).

Check Valve Condition Monitoring Maximum Intervals Group Size Maximum Interval Maximum Interval (years)

Between Activities of Member Valves in the Groups 4 4.5 16 3 4.5 12 2 6.0 12 1 N/A 10

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 57 of 304 5.3.27 Exercise Tests for Category C Check Valves (continued)

b. TMM-008, Check Valve Program Technical Requirements, documents the requirements of Appendix II to the OM Code and lists the tests, examinations and groupings that are applicable to a particular valve included in the Check Valve Condition Monitoring Program.

c. If the Check Valve Condition Monitoring Program for a valve or group of valves is discontinued, then the requirements of Section 5.3.27 Step 1 through Section 5.3.27 Step 4 must be applied.

d. Valves subject to the requirements of a Check Valve Condition Monitoring Program are identified by the reference to App. II in the Test Frequency column.

6. Valves in Systems Out of Service For valves in a system declared inoperable or not required to be operable, the exercising test schedule need not be followed. The valve shall be exercised and the schedule followed within 3 months of placing the system in an operable status.

7. Series Valve Pairs

a. If two check valves are in series configuration without provisions to verify individual reverse flow closure, and the plant safety evaluation assumes closure of either valve (not both), the valve pair may be operationally tested closed as a unit. If the plant safety evaluation assumes that a specific valve or both valves of the pair close to perform the safety function, the required valve(s) shall be tested to demonstrate individual valve closure.

8. Corrective Action for Check Valve Exercise Tests

a. If a check valve fails to exhibit the required change of obturator position, it shall be declared inoperable. A retest showing acceptable performance shall be run following any required corrective action before the valve is returned to service,

b. Check valves in a sample disassembly program that are not capable of being full stroked exercised, or have failed or have unacceptable valve internals, shall have the cause of the failure analyzed and the condition corrected. Other valves in the sample group that may also be affected shall be examined or tested during the same refueling outage.

c. Series valves tested as a unit in accordance with Section 5.3.27 Step 7 and fail to prevent reverse flow shall be declared inoperable, and both valves shall be either repaired or replaced.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 58 of 304 5.3.28 Tests for Category C Safety and Relief Valves

1. Tests for Category C Safety and Relief Valves are conducted in accordance with Appendix I of the OM Code.

a. Individual valve groups are determined based on manufacturer, type (safety, relief, vacuum breaker), media (water, air), and service application.

b. When calculating the number of valves required to be tested, resultant fractions shall be rounded to the next higher whole number (e.g., six valves in a Valve Group x 20% = two valves).

c. If only one valve exists in a Valve Group, it is required to be tested at the sampling frequencies specified in Section 5.3.29 and Section 5.3.30.

d. Bench testing of safety and relief valves will be completed in accordance with EST-027, Pressurizer Safety Valve Testing, EST-028, Main Steam Safety Valve Testing, and EST-112, Pressure, Safety and Relief Valve Bench Testing, as applicable.

e. Bench testing of Vacuum Breakers are completed in accordance with EST-068, Testing Spray Additive Tank Vacuum Breakers and EST-130, Testing CCW Surge Tank Vacuum Breaker, as applicable.

5.3.29 Testing Class 1 and Main Steam Safety Valves

1. At least 20% of the valves in each valve group shall be tested within any 24 month interval. This 20% shall include valves that have not been tested during the current 5 year interval, if they exist.

2. The test interval for any individual valve shall not exceed 5 years. This limit applies to any 5 year period. The 5-yr test interval shall begin from the date of the as-left set-pressure test for each valve.

3. For each valve tested in which the as-found set-pressure (first actuation) does not meet the acceptance criteria, two additional valves shall be tested from the same valve group.

4. If the as-found set-pressure of any of the additional valves tested does not meet the acceptance criteria, then all remaining valves within the same valve group shall be tested.

5. The cause and effect of any valve that fails to meet the as-found set pressure acceptance criteria shall be determined and documented. This information will be used to determine the need for any additional tests to address generic concerns that may apply to valves in the same group or in other groups.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 59 of 304 5.3.30 Testing Class 2, 3 or Augmented Safety Valves

1. At least 20% of the valves in each valve group shall be tested within any 48 month interval. This 20% shall include valves that have not been tested during the current 10 year interval, if they exist. For singular valve groups, the valve must be tested within any 48 month interval. The test interval shall begin from the date of the as-left set-pressure test for each valve.

2. The test interval for any individual valve shall not exceed 10 years. This limit cannot be exceeded and applies to any 10 year period.

3. For each valve tested in which the as-found set-pressure (first actuation) does not meet the acceptance criteria, two additional valves shall be tested from the same valve group.

4. If the as-found set-pressure of any of the additional valves tested does not meet the acceptance criteria, then all remaining valves within the same valve group shall be tested.

5. The cause and effect of any valve that fails to meet the as-found set pressure acceptance criteria shall be determined and documented. This information will be used to determine the need for any additional tests to address generic concerns that may apply to valves in the same group or in other groups.

5.3.31 Safety and Relief Valve Replacement

1. Test requirements may be satisfied by installing pretested valves to replace valves that have been in service provided the additional requirements listed below are satisfied. RNP typically elects to replace Class 1 valves with a full complement. This principle eliminates potential start up delays in the unlikely event that one valve fails to meet the acceptance criteria. Failure of one valve in the group would require scope expansion to include the remaining valves in the group prior to the resumption of electric power generation.

5.3.32 Replacement of Class 1 and Main Steam Safety Valves:

1. For the replacement of a partial complement of valve(s), the valve(s) removed from service shall be tested prior to the resumption of electric power generation.

2. For replacement of a full complement of valves, the valves removed from service shall be tested within 12 months of removal from the system.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 60 of 304 5.3.33 Replacement of Class 2 or 3 Safety and Relief Valve:

1. For the replacement of a partial complement of valves, the valves removed from service shall be tested within 3 months of removal from service, or prior to the resumption of electric power generation, whichever is later.

2. For replacement of a full complement of valves, the valves removed from service shall be tested within 12 months of removal from the system. Additional valves shall be tested as follows 5.3.34 Class 2 and 3 Thermal Relief Valves

1. Tests shall be performed on all Class 2 and 3 relief devices used in thermal relief application every 10 years unless performance data indicates more frequent testing is necessary.

2. In lieu of testing, thermal relief devices may be replaced every 10 years unless performance data indicates more frequent replacements are necessary.

5.3.35 Vacuum Relief Valves

1. CC-948 (CCW Surge Tank Vacuum Breaker), SI-899D (Spray Additive Tank Vacuum Breaker) and SI-899E (Spray Additive Tank Vacuum Breaker) are Vacuum Breaker, or Vacuum Relief Valves. These valves are capacity certified and subject to testing requirements per Appendix I of the OM Code for pressure relief devices.

5.3.36 Tests for Category D Explosively Actuated Valves

1. Not applicable to RNP.

5.3.37 Tests for Category D Rupture Disks

1. Not applicable to RNP.

5.3.38 Exercise Tests for Manual Valves

1. Manual valves shall be full stroke exercised at least once every 2 years, except where adverse conditions may require the valve to be tested more frequently to assure operational readiness. Any increased testing frequency shall be specified. The valve shall exhibit the required change of obturator position.

Hardship Without Compensating Increase in Quality and Safety ASME Code Components Affected Component Identification Category IVSW-71, 72, 74 thru 97, and 100A, B, and C (Check Valves) A

Applicable Code Edition and Addenda

American Society of Mechanical Engineers (ASME) Operation and Maintenance (OM) Code, 2017 Edition.

Applicable Code Requirement

ISTC-1300, Valve Categories defines uniform criteria for assigning valve categories. Category C valves are defined as valves that are self-actuating in response to some system characteristic, such as pressure (relief valves) or flow direction (check valves) for fulfillment of the required function(s), as specified in para. ISTA-1100.

ISTC-3510, Exercising Test Frequency requires Active Category A, Category B, and Category C check valves be exercised nominally every three months, paras. ISTC-3520, STC-3540, ISTC-3550, ISTC-3570, ISTC-5221, and ISTC-5222.

ISTC-3522(a), Category C Check Valves requires that Category C check valves be exercised or examined in a manner that verifies obturator travel by using methods in ISTC-5221. ISTC-3522(a) also requires each check valve exercise test shall include open and closed tests.

ISTC-3530, Valve Obturator Movement states that the necessary valve obturator movement shall be determined by exercising the valve while observing an appropriate indicator, such as indicating lights that signal the required changes of obturator position, or by observing other evidence, such as changes in system pressure, flow rate, level or temperature, that reflects change of obturator position.

ISTC-5221(a), Valve Obturator Movement specifies that the required obturator movement during exercise testing be demonstrated by performing both an open and a close test.

ISTC-5221(a)(2), Valve Obturator Movement specifies that check valves that have a safety function in only the open direction shall be exercised by initiating flow and observing the obturator has traveled either to the open position or to the position required to perform its intended function(s) and verify closure.

ISTC-5221(c)(2),Valve Obturator Movement specifies that full stroke motion of the obturator shall be verified if a sample disassembly examination program is used to verify obturator movement.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 68 of 304 ATTACHMENT 2 Page 2 of 29

<< Relief Requests >>

ISTC-5222, Condition Monitoring Program, as an alternative to the testing or examination requirements of paras. ISTC-3510, ISTC-3520, ISTC-3530, ISTC-3550, and ISTC-5221, the Owner may establish a condition monitoring program in accordance with Mandatory Appendix II, Check Valve Condition Monitoring Program. Section II-4000 of Appendix II, Condition Monitoring Activities specifies that valve obturator movement during applicable test or examination activities be sufficient to determine the bidirectional functionality of the moving parts.

Reason for Request

Pursuant to 10 CFR 50.55a(z)(2), relief is requested from the requirements of the ASME OM Code, 2017 Edition, Subsection ISTC 3522(a), ISTC-3530, ISTC-5221(a), ISTC-5221(a)(2),

ISTC-5221(c)(2) and ISTC-5222 that require Category C check valve exercise tests or exams include both open and closed tests (bidirectional functionality).

Specifically, relief is requested from the requirements of ISTC to verify closure and from the alternative requirements of Appendix II to verify bidirectional functionality. The check valves will be forward flow tested and closure verification will not be performed, as previously approved for the Fifth Inservice Testing Interval (see Section 7, Precedents).

Proposed Alternative and Basis for Use These 3/8 inch penetration check valves in the Isolation Valve Seal Water System (IVSW) system have no safety function in the closed direction and are required to open in order to provide seal water to selected containment penetrations during a Design Basis Accident (DBA).

The IVSW system operates to limit the release of fission products should leakage occur; however, no credit is actually taken for its operation when calculating off site accident dose. The system has been formally accepted as a qualified seal water system pursuant to 10 CFR 50 Appendix J requirements. IVSW is maintained at a minimum pressure of 1.1 times the peak accident pressure related to the design basis loss of coolant accident. As such, the design and qualification of the system eliminates the need for these valves to close during a DBA in the unlikely event that closure is required.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 69 of 304 ATTACHMENT 2 Page 3 of 29

<< Relief Requests >>

Disassembly to verify obturator closure or modifications to facilitate inservice testing for closure is impractical based on the large number of valves requiring verification and the insignificance associated with their failure to close. Disassembly may also lead to maintenance-induced errors associated with reassembly. The small size and construction of these valves prohibits the ability to perform partial disassembly / inspection in a manner representative of its inservice condition (e.g., valve removal and decontamination activities could alter disc position). IVSW is a standby system that is typically operated during refueling outages to facilitate testing. Based on infrequent use, the valve obturator exhibits minimal wear. Bi-directional check valve testing was adopted to counter the effects of a faulty test strategy associated with the inability to detect a detached valve disc. Specifically, a satisfactory forward flow check valve test could be completed when the valve disc is actually detached and laying in the bottom of the valve body.

Based on the design and materials of construction associated with these check valves, disc failure with subsequent migration into associated systems is not likely. The size of the disc exceeds the inner diameter of the valve outlet. It is likely that failure of the valve in this manner would be detected by the current test method which, is performed at refueling outages in conjunction with required Appendix J leak rate testing of the associated containment penetration.

Forward flow testing at a refueling interval is warranted since the test boundary must be depressurized to perform leak rate testing. Depressurization of the boundary is assured during the leak rate test conducted at refueling intervals. The location of these valves would make testing, inspection or examination for closure inconsistent with ALARA principles.

H. B. Robinson Steam Electric Plant (Robinson Nuclear Plant, RNP), Unit No. 2 began implementing an Appendix II Program on 2/19/2002; however, the IVSW check valves are not included in the Check Valve Condition Monitoring (CVCM) program because the small size and ball shape design of the disc would make dimensional measurements relatively difficult to obtain on a consistent basis. Consequently, effective condition monitoring to improve or optimize the health of the check valve would also be very difficult. Based on the design and qualification of this system, compliance with the Code requirement as written would result in an unusual hardship without a compensating increase in the level of quality and safety.

Proposed Alternative The 3/8-inch penetration check valves installed in the IVSW system will be tested to the open position at refueling intervals. Closure verification will not be performed.

Table ISTB-5321-2, Reciprocating Positive Displacement Pump Test Acceptance Criteria provides the values for the Alert Range and Required Action Range for inservice testing.

Reason for Request

Pursuant to 10 CFR 50.55a(z)(1), relief is requested from the requirements of the ASME OM Code, 2017 Edition, Subsection ISTB. The ASME Code committees have approved Code Case OMN-22, Smooth Running Pumps. This Code Case has not been approved for use in Regulatory Guide 1.192, Operation and Maintenance Code Case Acceptability, ASME OM Code, Revision 3, October 2019.

Code Case OMN-22 allows for alternative requirements for use with smooth running pumps in lieu of use of vibration values obtained in the reference value tests. For very low reference values, hydraulic noise and instrument accuracy can represent a significant portion of the reading and affect the repeatability of subsequent measurements. A smooth running pump could be subject to unnecessary increased testing if the measured vibration parameter exceeds an acceptable range based on these very low reference values.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 73 of 304 ATTACHMENT 2 Page 7 of 29

<< Relief Requests >>

Smooth running pumps have a much lower reference value for stable operation and the ranges for acceptable range and higher levels listed in the Alert Range do not allow for adequate vibration monitoring techniques to be applied to smooth running pumps.

Guidelines set forth in Code Case OMN-22, 'Smooth Running Pumps allow for a very low baseline vibration value with a pump vibration velocity of 0.050 in/sec when establishing the vibration reference value, which allows for trending of the pump vibration on a much lower scale than what is currently allowed.

ASME OM Code Case OMN-22, Smooth Running Pumps has not been approved by the NRC and a relief request is required for use of this Code Case.

Proposed Alternative and Basis for Use H. B. Robinson Steam Electric Plant (Robinson Nuclear Plant, RNP), Unit No. 2, proposes to utilize the provisions of Code Case OMN-22, Smooth Running Pumps. For those pumps with very low baseline vibration values ( 0.050 in/sec), the following vibration velocity criteria shall be applied to any vibration test points qualifying for the use of the minimum reference value:

Acceptable Range: 0.125 in/sec Alert Range: > 0.125 in/sec to 0.300 in/sec Required Action Range: > 0.300 in/sec Supplemental Monitoring Pumps that will use the "minimum reference" value for one or more vibration points shall be included in the Owners Predictive Maintenance (PdM) program. The PdM program shall apply predictive monitoring techniques and perform vibration analysis beyond the trending of vibration levels specified in the ASME OM Code to provide early identification of pump performance issues. The Owner shall determine which PdM Supplemental Monitoring activities will be utilized on the pump.

At a minimum, the Owner shall perform spectral analysis of measured vibration of the applicable pumps. The Owner shall document the conclusion of the PdM performance analysis on the pump test record prior to the subsequent test with a conclusion of acceptable, degrading but acceptable, or unacceptable. Corrective action shall be initiated when an unacceptable trend in performance is identified

Corrective Action If a measured pump vibration parameter falls within the alert range or the required action range specified above, then the 'Corrective Action' requirements of ISTB-6200 (2017 Ed.) shall be followed. The alert and required action ranges are established in accordance with this Code Case rather than the referenced pump tables.

If a PdM Supplemental Monitoring activity identifies a parameter outside the normal operating range or identifies a trend toward an unacceptable degraded state, action shall be taken to (1) identify and document the condition in the corrective action program (2) increase monitoring to establish the rate of change of the monitored parameter, (3) review component-specific information to identify the degradation cause, (4) develop a plan to remove the pump from service to perform maintenance prior to significant performance degradation, and (5) address potential common cause issues applicable to other pumps based on the results of the analysis of the specific pump performance.

In summary, RNP proposes to test the pumps listed in this request and other pumps in the IST Program that meet the requirements of Code Case OMN-22 in the future by implementing the requirements of ASME OM Code Case OMN-22. The use of OMN-22 requires NRC approval to implement this change since Code Case OMN-22 is not listed in Regulatory Guide 1.192.

Using the provisions of this request would provide adequate detection of component degradation and, would continue to provide reasonable assurance of the operational readiness of affected RNP components. Therefore, compliance with the requirements of ASME OM Code Case OMN-22 would result in an acceptable level of quality and safety pursuant to 10 CFR 50.55a(z)(1).

Applicable Code Requirement

The applicable ASME OM Code edition and addenda for the H. B. Robinson Steam Electric Plant (Robinson Nuclear Plant, RNP), Unit No. 2, Sixth 10-year IST interval is the 2017 Edition with no addenda. RNP is requesting an alternative to the requirements in Appendix I subparagraph I-1350, Test Frequency, Classes 2 and 3 Pressure Relief Valves Except PWR Main Steam Safety Valves, (a)(2): For valve groups containing only one valve, the valve shall be tested at least every 48 months.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 77 of 304 ATTACHMENT 2 Page 11 of 29

<< Relief Requests >>

Per I-1350(a)(1) The maximum allowable time between tests for any valve, with the exception of PWR main steam safety valves, shall not exceed 10 yr, starting with Initial electric power generation.

Reason for Request

RNP proposes to utilize the provisions of Code Case OMN-24. Pursuant to 10 CFR 50.55a, Codes and Standards, paragraph (z)(1), an alternative is proposed to ASME OM Code, I-1350(a)(2) requirements by implementing Code Case OMN-24, Alternative Rules for Testing ASME Class 2 and 3 Pressure Relief Valves (For Relief Valves in a Group of One). The basis of the request is that the proposed performance based alternative would provide an acceptable level of quality and safety. Also, the requirement within I-1350(a)(2) for a 48 month test interval would be relaxed. The change would remain within compliance of I-1350(a)(1) where the test interval would not exceed 10 years, with the Code Case allowing a six month grace period to coincide with refuel outages.

The ASME Code committees have approved Code Case OMN-24, Alternative Rules for Testing ASME Class 2 and 3 Pressure Relief Valves (For Relief Valves in a Group of One). This Code Case has not been approved for use in Regulatory Guide 1.192, Operation and Maintenance Code Case Acceptability, ASME OM Code, Revision 3, October 2019. This Code Case has been approved by ASME and is listed in the Applicability Index from ASME Codes and Standards, as applicable through the 2020 Edition of the ASME OM Code..

Proposed Alternative and Basis for Use RNP proposes to utilize the provisions of Code Case OMN-24:

The relief valve shall be tracked by its plant identification number as provided by its manufacturer or as applied by the Owner.

Upon adoption of this Code Case, the initial test interval shall not exceed 48 months since its last set-pressure test. A 12 month period is allowed to complete testing once the relief valve is removed from the system.

A relief valve that satisfies the as-found set-pressure test criterion may have its test interval extended by up to 24 months. The test interval shall begin from the date of the as-left set-pressure test for the installed valve.

A relief valve that fails the as-found set-pressure test shall have its test interval reduced by 24 months. The minimum required test frequency for this circumstance is a 24 month interval.

The test interval for any individual relief valve shall not exceed 120 months except that a six (6) month grace period is allowed to coincide with refueling outages to accommodate extended operation or shutdown periods.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 78 of 304 ATTACHMENT 2 Page 12 of 29

<< Relief Requests >>

The Owner may satisfy testing requirements by installing a pretested valve to replace the valve that had been in service provided that the valve removed from service shall be tested within 12 months of removal from the system.

In summary, RNP proposes an alternative to test the Relief Valves listed in this relief request by implementing the requirements of ASME OM Code Case OMN-24, Alternative Rules for Testing ASME Class 2 and 3 Pressure Relief Valves (For Relief Valves in a Group of One), as approved by ASME.

Using the provisions of this request would provide adequate detection of component degradation and, would continue to provide reasonable assurance of the operational readiness of affected RNP components. Therefore, compliance with the requirements of ASME OM Code Case OMN-24 would result in an acceptable level of quality and safety pursuant to 10 CFR 50.55a(z)(1).

Duration of Proposed Alternative This relief will be implemented during the RNP, Unit No. 2, Sixth Ten-Year Inservice Testing Interval for valves listed in Table 1 required by ASME OM Code, 2017 Edition, Subsection ISTC.

Applicable Code Edition and Addenda

American Society of Mechanical Engineers (ASME) Operation and Maintenance (OM) Code, 2017 Edition.

Applicable Code Requirement

Appendix I, subparagraph I-1320, "Test Frequencies, Class 1 Pressure Relief Valves", (a) 5-Yr Test Interval. "Class 1 Pressure relief valves shall be tested at least once every 5 yr, starting with initial electric power generation. No maximum limit is specified for the number of valves to be tested within each interval; however, a minimum of 20% of the valves from each group shall be tested within any 24-month interval. This 20% shall consist of valves that have been tested during the current 5-yr interval, if they exist. The test interval for any installed valve shall not exceed 5 yr.

The applicable ASME OM Code edition and addenda for H. B. Robinson Steam Electric Plant (Robinson Nuclear Plant, RNP), Unit No. 2, Sixth 10-year IST interval is the 2017 Edition with no addenda. RNP is requesting an alternative to the requirements in Appendix I, Sections I-1320 and I-1350, of the OM Code 2017 Edition with no Addenda, as it applies to the current maximum 5 year (test to test) interval imposed on Class 1 over pressure devices and Class 2 PWR Main Steam Safety Valves, the 48 month test requirement for Class 2 and Class 3 valve Groups containing one valve in the Group, minimum percentage test requirements for valves in Groups containing more than one valve, and the need to test additional valves in a Group as a result of a set-pressure failure of a valve in the applicable Group.

Reason for Request

RNP proposes to utilize the provisions of Code Case OMN-25. Pursuant to 10 CFR 50.55a, Codes and Standards, paragraph (z)(1), an alternative is proposed to ASME OM Code, Appendix I, part I-1320(a), I-1320(c), I-1350(a), and I-1350(c) requirements. The basis of this request is that the proposed "performance based" alternative would provide an acceptable level of quality and safety to Appendix I requirements.

OMN-25, Alternative Requirements for Testing Appendix I Pressure Relief Valves. provides a "Performance Based" alternative to the referenced ASME OM Code Appendix I requirements for over pressure devices. The concept of valve Groups with periodic percentage sampling requirements (I-1320(a) and I-1350(c)) is eliminated. The mandatory Appendix I, I-1350(a)(2) requirement to test a valve Group consisting of one valve on a recurring 48-month schedule is relaxed if supported by satisfactory test results. Maximum test intervals and rules for extending initial test intervals are provided in the Code Case.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 84 of 304 ATTACHMENT 2 Page 18 of 29

<< Relief Requests >>

The OM Code Appendix I maximum test interval for ASME Class 1 and ASME Class 2 PWR main steam safety valves of 5 years is increased to 72 months under OMN-25.

OMN-25 also replaces the mandatory test expansion requirements for a set-pressure failure delineated in I-1320(c)(1), I-1320(c)(2), I1350(c)(1), and I-1350(c)(2) of Appendix I. Under OMN-25, over-pressure devices that fail their set-pressure test have their "performance based" test interval reduced.

OMN-25 also modifies the "corrective action" requirements of Appendix I, I-1320(c)(3) and I-1350(c)(3), establishing its own set of requirements. As noted in the above paragraph, mandatory test sample testing expansion is not mandated, valves that fail set-pressure tests have their tests intervals reduced in lieu of test expansion. Repeat failures of serial number tracked valves are required to be evaluated to determine if adjustments are needed to their refurbishment schedule. Under OMN-25, valves on a minimum require test interval that fail a set-pressure test shall either be removed form service or completely refurbished. OMN-25 also requires upon identification of two consecutive failures of set-pressure tests for the same installed plant location, whether it be the same physical (serial numbered) valve or two different valves, the Owner shall conduct an evaluation to determine whether factors related to that location contributed to the set-pressure tests failures.

OMN-25 also requires the Owner to evaluate the cause and effect of valves that fail to comply with their set-pressure acceptance criteria, or Owner established acceptance criteria for other required tests, such as the acceptance of auxiliary actuating devices, compliance with the Owner's seat-tightness criteria, etc. Based on these evaluations, OMN- 25 requires the Owner to determine the need for testing in addition to the minimum tests specified in I-3300, as applicable to address any generic concerns that could apply to additional valves.

The ASME Code committees have approved Code Case OMN-25, Alternative Requirements for Testing Appendix I Pressure Relief Valves. This Code Case has not been approved for use in Regulatory Guide 1.192, Operation and Maintenance Code Case Acceptability, ASME OM Code, Revision 3, October 2019. This Code Case has been approved by ASME and is listed in the Applicability Index from ASME Codes and Standards, as applicable through the 2020 Edition of the ASME OM Code.

Proposed Alternative and Basis for Use RNP proposes to utilize the provisions of Code Case OMN-25:

Introduction This Code Case establishes alternative requirements for testing Pressure Relief Valves that would normally be tested per paragraph I-1320 or I-1350 in Appendix I to the ASME OM Code.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 85 of 304 ATTACHMENT 2 Page 19 of 29

<< Relief Requests >>

Performance Based Test Plan:

Each individual valve shall be tracked by its unique serial number as provided by its manufacturer or a unique identification as applied by the owner.

Upon adoption of this Code Case, the initial test interval shall be the effective interval between tests that was established under the ASME OM Code Appendix I sample plan requirements.

The initial test-to-test interval shall be at least 24 months up to a maximum of 72 months for Class 1 and at least 48 months up to a maximum of 120 months for Class 2 and 3.

The test interval for new valves added to the program scope subsequent to the adoption of this Code Case that have not previously been assigned a test interval as prescribed by ASME OM Code shall not exceed 24 months for ASME Class 1 or 48 months for ASME Class 2 and 3.

For each valve tested for which the as-found set-pressure is within the +/- tolerance limit of the Owner-established set-pressure acceptance criteria of subparagraph I- 1310(e) or +/- 3% of valve nameplate set-pressure, the test interval may be extended by up to 24 months.

A valve that fails the as-found set-pressure test shall have its test interval reduced by 24 months. The minimum required test interval is at least once every 24 months.

The owner may satisfy testing requirements by installing a pretested spare valve to replace the valve that has been in service. Class 1 valves shall be tested before the resumption of electric power generation. Class 2 and 3 valves removed from service shall be tested within 3 months or before resumption of electric power generation, whichever is later.

For replacement of a full complement of valves in a group, the valves removed from service shall be tested within 12 months of removal from the system.

The test interval for any individual ASME Class 1 or ASME Class 2 PWR Main Steam Safety valve that is in service shall not exceed 72 months.

The test interval for any individual ASME Class 2 or 3 valve that is in service shall not exceed 120 months.

Corrective Action Valves that fail the as-found set-pressure test shall have their test interval reduced as described by 2(e). Repeated failures of the same serial numbered valve shall be evaluated to determine if adjustments are needed to the refurbishment schedule.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 86 of 304 ATTACHMENT 2 Page 20 of 29

<< Relief Requests >>

If a valve is currently on a minimum required test interval fails its set-pressure test, the valve shall either be permanently removed from service or completely refurbished. If the valve is complete refurbished, performance testing shall be conducted in accordance with I-3400 to qualify repeatable acceptable set-pressure performance prior to re-installation.

Upon identification of two consecutive valve failures of set-pressure tests for the same installed plant location, whether it be the same physical (serial number) valve or two different valves, the Owner shall conduct an evaluation to determine whether factors related to the location contributed to the set-pressure test failures.

The Owner shall evaluate the cause and effect of valves that fail to comply with their set-pressure acceptance criteria, or the Owner established acceptance criteria for other required tests, such as the acceptance of auxiliary actuating devices, compliance with the Owner's seat-tightness criteria, etc. Based upon this evaluation, the Owner shall determine the need for testing in addition to the minimum tests specified in I-3300, as applicable to address any generic concerns that would apply to additional valves.

Documentation Corrective actions and changes to the test intervals, with the basis for doing so, shall be documented in the record of tests described by section I-5000 "Records and Record Keeping" in Appendix I to the ASME OM Code.

In summary, RNP proposes to test the Relief Valves listed in this request by implementing the requirements of ASME OM Code Case OMN-25, 'Alternative Requirements for Testing Appendix I Pressure Relief Valves", as approved by ASME.

Using the provisions of this request would provide adequate detection of component degradation and would continue to provide reasonable assurance of the operational readiness of affected RNP components. Therefore, compliance with the requirements of ASME OM Code Case OMN-25 would result in an acceptable level of quality and safety pursuant to 10 CFR 50.55a(z)(1).

Duration of Proposed Alternative This relief will be implemented during the RNP, Unit No. 2, Sixth Ten-Year Inservice Testing Interval for valves required by ASME OM Code, 2017 Edition, Subsection ISTC.

<< Relief Requests >>

For each of these paragraphs, relief is being requested for alternative treatments described in Section 5 of this Relief Request based on the ASME Board of Nuclear Codes and Standards (BNCS) approved Code Case OMN-26.

Reason for Request

In accordance with 10 CFR 50.55a (z)(1), H. B. Robinson Steam Electric Plant (RNP),

Unit No. 2, is requesting approval to adopt ASME OM Code Case OMN-26, 'Alternate Risk-Informed and Margin Based Rules for Inservice Testing of Motor Operated Valves', in conjunction with implementing Mandatory Appendix III as part of the 2017 Edition of the OM Code.

Code Case OMN-26 better aligns the inservice test intervals in Mandatory Appendix Ill to the Risk and Margin Based Licensee Motor Operated Valve (MOV) Programs developed in response to NRC Generic Letter 96-05, "Periodic Verification of Design-Basis Capability of Safety Related Motor-Operated Valves," that have been in effect since 1998. There is no formal technical basis in Appendix III for limiting the maximum inservice test interval to 10 years. Code Case OMN-26 establishes a structured risk-informed approach for determining inservice intervals that provides an acceptable level of quality and safety while providing RNP additional inservice test schedule flexibility.

Proposed Alternative and Basis for Use Proposed Alternative:

RNP proposes to implement the ASME OM Code Case OMN-26 alternative risk and margin informed rules for inservice testing of MOVs in its entirety as described below:

Proposed Alternative to III-3310 (c)

The maximum inservice test interval shall not exceed 10 years unless Risk Informed Inservice Testing applies under the alternative provisions of Code Case OMN-26 to para. III- 3700. MOV inservice tests conducted per para. III-3400 may be used to satisfy this requirement.

Proposed Alternative to III-3700 Risk-informed MOV inservice testing that incorporate risk insights in conjunction with MOV Functional Margin to establish MOV groupings, acceptance criteria, exercising requirements and test interval may be implemented.

Basis for Use:

The requested relief to adopt OMN-26 is in line with the current JOG MOV Periodic Verification Test Program that RNP has implemented at RNP in response to NRC Generic Letter 96-05.

Both the JOG MOV PV Program and Code Case OMN-26 provide a Risk- Margin based methodology that establishes limitations for maximum inservice test intervals for MOVs. Code Case OMN-26 simply provides a reasonable extension of this Risk-Informed philosophy based on the lessons learned and accumulated MOV performance data gathered during MOV Performance Verification Testing. Appendix III alone, isolated from OMN-26, provides no such methodology other than a maximum limit for the inservice test interval regardless of Risk or Margin.

The requested allowed maximum inservice test intervals are modest extensions with many of the Low Risk MOVs extending from 10 to 12 years (20% increase). This test interval change can be readily adopted with no loss of MOV performance and/or safety system reliability provided that no adverse performance trends are indicated. RNP's MOV Performance Trending Governance will ensure that only MOV's with good performance history, high stable margins and no adverse diagnostic trends would be candidates for the OMN-26 based inservice test interval extensions.

The requested High Margin Maximum interval changes afforded by OMN-26 align with RNP's desire to adopt a divisional MOV outage testing strategy that reduces the implementation burden of MOV Inservice Testing and allows greater flexibility in optimizing safety system availability. The current six and ten-year JOG Program based High-Margin Maximum Intervals do not support this strategy.

The requested relief reduces the maximum test interval for High Safety Significant Component (HSSC) MOVs allowed by Appendix III from ten years to nine years commensurate with Risk Informed Methodology. Further under this relief request, RNP will treat MOVs currently classified as Medium Risk by the 3-Tier JOG Risk Ranking as High Risk (HSSC) thereby providing more rigorous periodic verification requirements for the applicable valves especially those with less than high margin.

The requested relief takes credit for routine design basis differential pressure testing (DBDPT) of MOVs to justify extending the maximum Inservice test interval to 12 Years for Very High Margin HSSC MOVs and 16 years for Very High Margin Low Safety Significant Component (LSSC) MOVs.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 93 of 304 ATTACHMENT 2 Page 27 of 29

<< Relief Requests >>

With the exception of Low Risk MOVs routinely operated at design basis differential pressure (D-P) conditions, Code Case OMN-26 does not allow maximum MOV Inservice Test intervals to exceed ten years unless the associated MOVs are classified as High Margin. Most High Risk MOVs are limited to four years or less for Low/Medium Margins and most Low Risk MOVs are limited to nine years or less for Low/Medium Margins. Code Case OMN-26 provides more rigorous requirements targeted specifically to Low/Medium Margin MOVs than currently allowed under Appendix III. This Risk/Margin approach is in line with accepted Risk-Informed Strategies such as the JOG MOV Periodic Verification Program.

Use of the proposed alternative is expected to result in improved MOV Margins at RNP in order to attain higher margin status to allow use of the extended maximum inservice test intervals permitted by the OMN-26 Code Case.

For the majority of applicable MOVs (i.e., those MOVs not subject to periodic stroking under design basis D-P conditions), the Code Case limited the scope to only High Margin Valves for extending test intervals incrementally beyond current limits:

• Test intervals for High Risk MOVs go from six to nine years (Note: Nine years is aligned to Pressurized Water Reactor nuclear power plants (PWRs) on 18-month refueling cycles)

• Test intervals for Low Risk MOVs go from ten to 12 years (Note: 12 years is aligned for all Boiling Water Reactor nuclear power plants (BWRs) and PWRs with either 18- or 24- month refueling cycles)

Table Notes

5. Except for Low Margin HSSC MOVs, the Maximum MOV Inservice Test Intervals are optimized for Divisional Outage Scheduling (i.e., 4, 9, 12, 16 years). Nine years is optimal for PWRs restricted to 18 month refueling outages. 12 years is optimal for both PWRs and BWRs and supports both 18-month and 24-month refueling outages.

6. To utilize these intervals, test strokes at or exceeding design basis system conditions must occur at a periodicity no less frequent than once a refueling cycle, must be in the applicable safety function direction(s),

and the MOV must have no applicable operating experience, degradation or diagnostic test anomaly with the potential for adverse impact on MOV functional margin or the capability of the MOV to perform its design basis function. These routine strokes during the inservice test interval are not required to be diagnostically monitored.

7. Operating plants that have acquired the requisite test data to satisfy Appendix III, paragraphs III-3310(b) or III-3722(c) must complete one cycle of collecting diagnostic test data at an extended test interval, minimum 9 and maximum 12 years, before extending the test interval by engineering evaluation to the maximum 16-year test interval.

8. The MOV functional margin limits apply to the As-Left MOV condition at the start of the inservice test interval and includes applicable test uncertainties and allowance for service-related degradation.

Deferred Testing Quarterly stroke time, full stroke exercise and fail safe Test.

Cold Shutdown Test Justification Exercising these valves during power operation would isolate CVCS letdown causing pressurizer level to increase, charging flow to decrease and interrupt letdown flow to the regenerative heat exchanger. This would result in abnormal operating conditions and may result in a plant transient or unit trip due to pressurizer level variations, letdown line restoration events and uncontrolled positive reactivity addition as a result of cold water injection. Failure of any valve in the test position would isolate letdown. The valves are not designed to facilitate a part stroke exercise. Therefore, a partial stroke exercise test will not be performed since it may result in the same condition that would be encountered during the performance of a full stroke exercise test.

Loop 2 Cold Leg.

Deferred Testing Quarterly stroke time, full stroke exercise and fail safe Test.

Cold Shutdown Test Justification Exercising these valves to the required test position will result in temporary changes in flow to the RCP seals and may induce additional thermal stresses. Due to the passive status related to this section of piping, manipulating CVC-310A and CVC-310B may lead to uncontrolled reactivity additions when this volume of water is injected into the RCS. When restoring the plant to the desired configuration, CVC-310B must be reopened resulting in additional RCP seal perturbation before CVC-310A can be closed. Failure of the valve in the test position would require that the alternate pathway for boron injection remain in service and is not desired. These valves are not designed to facilitate a part stroke exercise. Therefore, a partial stroke exercise test will not be performed since it may result in the same condition that would be encountered during the performance of a full stroke exercise test.

Cold Shutdown Test Justification Operation of these valves during power operations will create temporary disturbances to the letdown flow control system, resulting in a potential challenge to letdown line relief valves, CVC-203A or CVC-203B, in the event of orifice isolation valve problems, switch mis-position events, or controller PCV-145 response errors. These events could lead to an inadvertent relief valve lift, and possible failure to re-close, resulting in an uncontrolled loss of primary coolant. In addition, cycling of these components could lead to temporary pressurizer level perturbations which may invalidate the transient analysis assumptions of UFSAR Chapter 15 as well as unnecessary changes to RCP seal injection flows. Although orifice isolation valve / relief valve discrepancies are not anticipated, the risk involved with exercising these valves is not warranted when performed with the sole purpose of satisfying IST requirements for normally scheduled on line surveillance activities. The valves are not designed to facilitate a part stroke exercise.

Therefore, a partial stroke exercise test will not be performed since it may result in the same condition that would be encountered during the performance of a full stroke exercise test.

Failure of these valves in the test position will result in a plant trip. The Feed water Regulating Bypass valves are normally in the required safety position at power, except during plant start up or shut down. Operation of the Bypass valves will induce temporary changes to the feed water flow rate and increase the risk of a plant transient or unit trip. Operation of these valves to complete testing is not consistent with the bases of Technical Specifications as stated in ITS SR 3.7.3.1.

These valves fail open upon loss of air or power. The Isolation Valve Seal Water (IVSW) system is in service when containment isolation is required to prevent affecting off-site dose calculation. These valves are open during accident and post-accident conditions to provide seal water to the containment isolation valves to maintain containment leakage within acceptable appendix J limits. IVSW is a credited 30-day seal water system per 10 CFR 50 App. J requirements. Because this valve is not within the ASME Code class boundary, this component is classified as augmented within the testing program.

Deferred Testing Quarterly stroke time, full stroke exercise and fail safe test.

Cold Shutdown Test Justification These augmented Non-Code air operated valves have been historically tested during cold shutdowns as allowed by ISTC-35210(c), ISTC-3521(f), and ISTC-3521 (g). During the individual testing of these valves, the respective inlet and outlet manual isolation valve for each is repositioned from the normally locked open to closed position. The fail open and stroke timed open test is performed by the removal of fuses from Auxiliary Panel DC circuit 45 (PCV-1922A) and Auxiliary Panel DC circuit 41 (PCV-1922B). It is preferable to perform these tests in Modes 5, 6 or no Mode in which the redundancy of the IVSW system is not challenged (required) and the inherent risks associated with the removal of fuses from DC control panels associated with other protective features also does not exist.

This valve is self-actuated open to supply automatic nitrogen from high pressure bottles, or plant nitrogen supply header to the IVSW injection tank to maintain the IVSW injection tank at a pressure greater than the 1.1 times the containment design pressure (approximately 46.2 psig). Tank pressure is maintained at 54 psig. IVSW is a credited 30-day seal water system per 10 CFR 50 App. J requirements. Because this valve is not within the ASME Code class boundary, these check valves are classified as augmented within the Inservice Testing Program.

Deferred Testing Quarterly full stroke exercise open.

Cold Shutdown Test Justification Testing this Non-Code, augmented check valve in the open direction requires partially draining the Isolation Valve Seal Water (IVSW) injection tank, manipulating a number of manual valves and isolating the IVSW header, rendering the entire system inoperable and requiring entry into Technical Specification (TS) Limiting Conditions for Operation (LCO) under TS 3.6.8. Entry into LCO 3.6.8(A) requires restoring the system to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. In addition, inoperability of the IVSW system is considered a loss of a safety function in accordance with Appendix B (Safety Function Determination Program) of the Technical Requirements Manual (TRM). If a failure were to occur during testing, the time required to conduct potential repairs (Including establishing a clearance, making the required repairs or replacement and performing the required retests) could challenge the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> LCO timeframe and place the plant at risk of having to shut down.

Cold Shutdown Test Justification These valves are not needed for overpressure protection during power operation. The safety function of these valves is to protect the reactor vessel and the Reactor Coolant System from low temperature overpressure conditions. During power operations, the valves are closed to provide an RCS barrier. Operation of these valves quarterly will reduce the RCS barrier protection when opened and may lead to excessive RCS leakage if the upstream valve is mis-positioned or leaking by.

SI-VCS-4 Valve ID Description SI-889A CV Spray Eductor Feed Check SI-889B CV Spray Eductor Feed Check SI-889C CV Spray Pumps Test Line Check Vlv to RWST Function SI-889A/B - Open to admit sodium hydroxide injection during Containment Spray system actuation. Closes to prevent flow from the Containment Spray Pump minimum flow line from entering the Spray Additive Tank.

SI-889C - Close to provide the ASME Code Class 2 to non-code boundary isolation and prevent diversion of flow from the Safety Injection (SI) pumps minimum flow line.

Deferred Testing Quarterly full stroke exercise open and closed.

Cold Shutdown Test Justification Reverse flow exercising these valves during power operation would render the entire Spray Additive System inoperable. Forward flow exercising of these valves requires isolation of the Spray Additive Tank in order to perform a line flush if the desired chemistry requirements are not met, as well as imposing additional risk associated with contamination of the RWST with NaOH.

The sample and flush alignment renders the Spray Additive System inoperable, and would require manual operator action involving multiple valve operations to restore this essential feature. Forward flow testing of either component renders the Spray Additive System inoperable once SI-892D (manual eductor test line isolation) is opened to facilitate the flow path necessary to open these valves. Additional test equipment set - up is required to complete the test.

Cold Shutdown Test Full stroke exercise open and closed.

SI-VCS-5 Valve ID Description SI-856A SI Pump Recirc SI-856B SI Pump Recirc Function Open to provide a mini-flow path back to RWST. Close during the transition from the injection mode of SIS operation to the recirculation mode of operation to prevent the discharge of containment sump water to the RWST and the potential release of activity through the RWST vent line when the SI Pumps are used during the recirculation mode.

Deferred Testing Quarterly stroke time, full stroke exercise and fail safe test.

Cold Shutdown Test Justification Exercising these valves during power operations with the SI Pumps racked in creates the potential for a pump start and run without a minimum flow path available. This condition increases the potential for possible pump damage and safety system unavailability. Failure in a non-conservative direction will result in total loss of system function. The valves are not designed to facilitate a part stroke exercise. Therefore, a partial stroke exercise test will not be performed since it may result in the same condition that would be encountered during the performance of a full stroke exercise test.

Deferred Testing Quarterly stroke time, full stroke exercise and fail safe test.

Cold Shutdown Test Justification Exercising these valves while at power creates the potential for valve failure in the non-conservative direction, which would cause a loss of system function during a large break loss of coolant accident as a result of the diversion of flow from the core to the affected Safety Injection accumulator. The valves are not designed to facilitate a part stroke exercise. Therefore, a partial stroke exercise test will not be performed since it may result in the same condition that would be encountered during the performance of a full stroke exercise test.

SI-VCS-7 Valve ID Description SI-861A CV Sump Recirc Suction SI-861B CV Sump Recirc Suction Function Open to provide flow path for recirculation phase of RHR. SI-861A closes to provide containment isolation capability for containment penetration P-46 and SI-861B closes to provide containment isolation capability for containment penetration P-47.

Deferred Testing Quarterly stroke time and full stroke exercise.

Cold Shutdown Test Justification Routine cycling of these valves results in fluid being directed to the ECCS sump. When the sump level is above the watertight construction joints, water may flow into the construction joints through cracks or possibly degraded areas that have lost seal integrity. The borated water then flows along the joint at the bottom of the crane wall until other possibly degraded areas of the joint are encountered. At these locations, the borated water flows out onto the floor in the annulus area and follows the path of least resistance to the lowest point of gravity. The typical flow path from the joint at the bottom of the crane wall is along floor construction joints, which originate at the bottom of the crane wall and terminate at the outer CV wall.

SW-VCS-1 Valve ID Description V6-16C Service Water Isolation To Turbine Building Function Close to isolate service water header from turbine building.

Deferred Testing Quarterly stroke time and full stroke exercise.

Cold Shutdown Test Justification Exercising this valve during power operation would temporarily isolate service water to all components in the turbine building and may result in damage to major plant equipment and a plant trip. Valve failure in the test position would require a plant shutdown or trip and may result in damage to plant equipment. The valve is not designed to facilitate a part stroke exercise.

Therefore, a partial stroke exercise test will not be performed since it may result in the same condition that would be encountered during the performance of a full stroke exercise test.

IA-VRS-1 Valve ID Description PCV-1716 Instrument Air Isolation to CV Function Close to provide containment isolation per 10CFR50, Appendix J.

Deferred Testing PCV-1716 - Quarterly and cold shutdown stroke time, full stroke exercise and fail safe test.

Refueling Shutdown Test Justification PCV-1716 is normally open to provide instrument air to components located in containment.

Exercising this valve during power operation or cold shutdown would isolate instrument air from components inside containment which could result in a plant trip or reduce the level of safety in order to maintain stable plant operation. The valve is tested closed via seat leakage measurement to meet the requirements of 10 CFR 50, Appendix J. PCV-1716 is not designed to facilitate a part stroke exercise. Therefore, a partial stroke exercise test will not be performed since it may result in the same condition that would be encountered during the performance of a full stroke exercise test.

IVSW-VRS-1 Valve ID Description IVSW-66B N2 Header Supply to Seal Water Injection Tank Check Function This is a normally closed check valve, that if open, closes to prevent loss of nitrogen from the Isolation Valve Seal Water (IVSW) injection tank in the event the plant nitrogen supply becomes unavailable. It also closes the prevent diversion of the backup nitrogen supply should the plant nitrogen supply become unavailable. The IVSW system is in service when containment isolation is required to prevent affecting off-site dose calculation. Because this valve is not within the ASME Code class boundary, this component is classified as augmented within the testing program.

Deferred Testing Quarterly full stroke exercise open and closed.

Refueling Outage Test Justification This valve is normally open or closed as necessary to provide the normal supply of nitrogen to the Isolation Valve Seal Water (IVSW) injection tank. It must close to ensure a reliable supply of nitrogen to the IVSW injection tank in the event the plant nitrogen supply becomes unavailable.

This valve is tested for closure in support of this function. Performance of this closure test requires disconnecting the inlet tubing from IVSW-66B in order to identify leakage through the valve. Disassembly of this tubing each quarter would place undue stress on this component and could reduce the life expectancy of it due to the repeated disassembly. Based on this, its determined to be impractical to perform the closure test each quarter. Testing at cold shutdown is impractical for the same reason. Therefore, closure testing of IVSW-66B will be performed at a refueling interval.

Refueling Outage Test Full stroke exercise closed.

LWD-VRS-1 Valve ID Description WD-1713 Nitrogen Supply Check Valve to Reactor Coolant Drain Tank Isolation Function WD-1713 is a normally closed check valve that is closed in support of containment isolation for Containment Penetration P-4 as the outboard Containment Isolation Valve (CIV). The nitrogen supply to the Reactor Coolant Drain Tank (RCDT) is Class 3 on the basis that the flow is incoming, the line is intermittently in use during normal plant operation and the line is not connected to a closed system inside containment.

Deferred Testing Quarterly full stroke exercise open and closed.

Refueling Outage Test Justification This valve is normally closed to provide containment integrity. The initiation of flow through the valve is intermittent during normal operation to maintain nitrogen in the Reactor Coolant Drain Tank (RCDT). Because the valve is normally closed, it is already in the position required to mitigate the consequences of an accident. The valve is tested closed via seat leakage measurement to meet the requirements of 10 CFR 50, Appendix J each refueling outage.

Performance of this leakage test requires disassembly of tubing between valves WD-1713 and WD-1896. Disassembly of this tubing each quarter would place undue stress on this component and could reduce the life expectancy of it due to the repeated disassembly. Based on this, its determined to be impractical to perform the open test each quarter. Testing at cold shutdown is impractical for the same reason. Therefore, the bi-directional open test will be performed at a refueling interval as permitted per ASME OM Code Paragraph ISTC-3522(a), which states Open and close tests need only be performed at an interval when it is practicable to perform both tests.

Refueling Outage Test Full stroke exercise open and closed.

OPP-VRS-1 Valve ID Description OPP-7 Instrument Air Check Valve Train A OPP-8 Instrument Air Check Valve Train B OPP-9 Nitrogen Check Valve 'A' Train OPP-10 Nitrogen Check Valve 'B' Train Function These 0.5" and 0.75 check valves that close to prevent back leakage of nitrogen from Accumulator B / A respectively, which would result in loss of nitrogen pressure needed for the operation of pressurizer Power-Operated Relief Valve (PORVs) PCV-455C / PCV- 456 respectively, to provide overpressure protection, as required, to achieve RCS Low Temperature Overpressure Protection (LTOPP).

Deferred Testing Quarterly full stroke exercise open and closed.

Refueling Outage Test Justification To perform the open and close exercise of these check valves on a quarterly or cold shutdown frequency, access is required into the containment for valve manipulations, test equipment installation and depressurization of the system pressure. Performance of these tests during operation would expose personnel to high neutron radiation. During Cold Shutdowns, personnel would still experience unnecessary radiation exposure. In addition, testing of these valves could render the Pressurizer Power Operated Relief Valves (PORVs) inoperable during testing, requiring entry into Technical Specification (TS) Limiting Conditions for Operation (LCO) under TS 3.4.11 during operation and TS 3.4.12 in modes 4, 5 and 6 unless the Reactor Coolant System (RCS) is vented. Therefore, quarterly or cold shutdown testing is impractical due to personnel exposure to radiation, potential inoperability of safety-related equipment and entry into TS LCOs.

Refueling Outage Test Full stroke exercise open and closed.

OPP-VRS-2 Valve ID Description OPP-14 'B' Accumulator Discharge Check OPP-15 'A' Accumulator Discharge Check Function These are 0.75" check valve which open to provide nitrogen supply from Accumulator B

/ A respectively, to pressurizer Power-Operated Relief Valve (PORV) PCV-455C / PCV- 456 respectively, as needed for operation of the valve.

Deferred Testing Quarterly full stroke exercise open and closed.

Refueling Outage Test Justification To perform the open and close exercise of these check valves on a quarterly or cold shutdown frequency, access is required into the containment for valve manipulations, test equipment installation and depressurization of the system pressure. Performance of these tests during operation would expose personnel to high neutron radiation. During Cold Shutdowns, personnel would still experience unnecessary radiation exposure. In addition, testing of these valves could render the Pressurizer Power Operated Relief Valves (PORVs) inoperable during testing, requiring entry into Technical Specification (TS) Limiting Conditions for Operation (LCO) under TS 3.4.11 during operation and TS 3.4.12 in modes 4, 5 and 6 unless the Reactor Coolant System (RCS) is vented. Therefore, quarterly or cold shutdown testing is impractical due to personnel exposure to radiation, potential inoperability of safety-related equipment and entry into TS LCOs.

IVSW-TP-1 TECHNICAL POSITION for Non-Performance of Bi-directional test of Non-Code (NC) Check Valves in the IVSW System ASME Code Components Affected Component Identification Category IVSW-66B and IVSW-68A/B/C/D Aug-C

Applicable Code Edition and Addenda

American Society of Mechanical Engineers (ASME) Operation and Maintenance (OM) Code, 2017 Edition.

Applicable Code Requirement

ISTC-1300, "Valve Categories" defines uniform criteria for assigning valve categories. Category C valves are defined as "valves that are self-actuating in response to some system characteristic, such as pressure (relief valves) or flow direction (check valves) for fulfillment of the required function(s), as specified in para. ISTA-1100."

ISTC-3510, "Exercising Test Frequency" requires Active Category A, Category B, and Category C check valves be exercised nominally every three months.

ISTC-3522(a), "Category C Check Valves" requires that Category C check valves be exercised or examined in a manner that verifies obturator travel by using methods in ISTC-5221.

ISTC-3522(a) also requires each check valve exercise test shall include open and closed tests.

ISTC-3530, "Valve Obturator Movement" states that the necessary valve obturator movement shall be determined by exercising the valve while observing an appropriate indicator, such as indicating lights that signal the required changes of obturator position, or by observing other evidence, such as changes in system pressure, flow rate, level or temperature, that reflects change of obturator position.

ISTC-5221(a), "Valve Obturator Movement" specifies that the required obturator movement during exercise testing be demonstrated by performing both an open and a close test.

ISTC-5221(a)(2), "Valve Obturator Movement" specifies that check valves that have a safety function in only the open direction shall be exercised by initiating flow and observing the obturator has traveled either to the open position or to the position required to perform its intended function(s) and verify closure.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 295 of 304 ATTACHMENT 9 Page 2 of 11

<< Technical Position >>

ISTC-5221(c)(2),"Valve Obturator Movement" specifies that full stroke motion of the obturator shall be verified.

ISTC-5222, "Condition Monitoring Program," requires that the program be implemented in accordance with Mandatory Appendix II, "Check Valve Condition Monitoring Program", Section II-4000 of Appendix II, "Condition Monitoring Activities" specifies that valve obturator movement during applicable test or examination activities be sufficient to determine the bidirectional functionality of the moving parts.

Reason for Request

Pursuant to 10 CFR 50.55a(f)(6)(ii), Augmented IST Requirements is requesting relaxation from the requirements of the ASME OM Code, 2017 Edition, Subsection ISTC 3522(a), ISTC-3530, ISTC-5221(a), ISTC-5221(a)(2), ISTC-5221(c)(2) and ISTC-5222 that require Category C check valve exercise tests or exams include both open and closed tests (bidirectional functionality).

Continued operation of the check valves will be verified via ISTC for closure (CVC) only of the IVSW-66B and opening (CVO) only of the IVSW-68A/B/C/D. Bi-directional (Non-Safety) testing (BDO) opening for the ISVW-66B and (BDC) closing for the IVSW-68A/B/C/D will not be performed via ISTC nor the requirements of Appendix II to verify bidirectional functionality.

Proposed Alternative and Basis for Use These 3/8 inch penetration check valves (IVSW068A/B/C/D) in the Isolation Valve Seal Water System (IVSW) system have no safety function in the closed direction and are required to open in order to provide nitrogen to the Seal Water Injection Tank during a Design Basis Accident (DBA). The IVSW-66B is tested to close to maintain the nitrogen boundary integrity during this period, it need not open, based on the supply of nitrogen not needing to be supplied by the normal path, but only the emergency nitrogen bottle path during the DBA.

The IVSW system operates to limit the release of fission products should leakage occur; however, no credit is actually taken for its operation when calculating off site accident dose. The system has been formally accepted as a qualified seal water system pursuant to 10 CFR 50 Appendix J requirements. IVSW is maintained at a minimum pressure of 1.1 times the peak accident pressure related to the design basis loss of coolant accident. As such, the design and qualification of the system eliminates the need for these valves to close during a DBA in the unlikely event that closure is required.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 296 of 304 ATTACHMENT 9 Page 3 of 11

<< Technical Position >>

Disassembly to verify obturator closure or modifications to facilitate inservice testing for closure/opening is impractical based on the large number of valves within the IVSW system as a whole (reference IST-RR-3) requiring verification and the insignificance associated with their failure to close. Disassembly may also lead to maintenance-induced errors associated with reassembly. The small size and construction of these valves prohibits the ability to perform partial disassembly / inspection in a manner representative of its inservice condition (e.g., valve removal and decontamination activities could alter disc position). IVSW is a standby system that is typically operated during refueling outages to facilitate testing. Based on infrequent use, the valve obturator exhibits minimal wear. Bi-directional check valve testing was adopted to counter the effects of a faulty test strategy associated with the inability to detect a detached valve disc.

Specifically, a satisfactory forward/reverse flow check valve test could be completed when the valve disc is actually detached and laying in the bottom of the valve body. Based on the design and materials of construction associated with these check valves, disc failure with subsequent migration into associated systems is not likely. The size of the disc exceeds the inner diameter of the valve outlet. It is likely that failure of the valve in this manner would be detected by the current test method which, is performed at refueling outages in conjunction with required Appendix J leak rate testing of the associated containment penetration. Forward/Reverse flow testing at a refueling interval is warranted since the test boundary must be depressurized to perform leak rate testing.

Depressurization of the boundary is assured during the leak rate test conducted at refueling intervals. The location of these valves would make testing, inspection or examination for closure inconsistent with ALARA principles.

Based on the design and qualification of this system, compliance with the Code requirement would result in an unusual hardship without a compensating increase in the level of quality and safety. The proposed alternative provides an acceptable level of quality and safety.

Proposed Alternative The 3/8-inch penetration check valves installed in the IVSW system will be tested to the open/closed position at refueling intervals. Closure/Open verification will not be performed.

Implementation Schedule This relaxation will be implemented during the HBRSEP, Unit No. 2, Sixth Ten-Year Inservice Testing Inspection for pumps required by ASME OM Code, 2017 Edition, Subsection ISTC.

Precedents The NRC granted relief to HBRSEP, Unit No. 2 for the Fifth IST Interval via letter dated July 13, 2012. [ML12174A010]

TP-MOV-1 TECHNICAL POSITION FOR APPENDIX III Prepared by: Chad Smith, 1/12/2023 Concurred by: Neal Estep (Kalsi Engineering), 1/12/2023

Purpose:

The purpose of TP-MOV-1 is to document how RNP meets the Exercising requirements in Appendix III and the associated NRC conditions. Each requirement is listed below along with an implementation approach that addresses the requirement. Results are shown in Table 1 for each MOV.

Requirements and Implementation:

III-3610 Normal Exercising Requirements All MOVs shall be full cycle exercised at least once per refueling cycle with the maximum time between exercises to be not greater than 24 months. Full cycle operation of an MOV, as a result of normal plant operations or Code requirements, may be considered an exercise of the MOV, if documented. If full stroke exercising of an MOV is not practical during plant operation or cold shutdown outages, full stroke exercising shall be performed during the plant's refueling outage.

Implementation:

RNP will exercise each MOV at least every 24 months unless more frequent exercising is required. See Table 1.

III-3620 Additional Exercising Requirements The maximum exercise interval for MOVs is 24 months (per III-3610). Paragraph III-3620 states that the Owner shall consider more frequent exercising requirements for MOVs in any of the following categories:

• MOVs with high risk significance

• MOVs with adverse or harsh environmental conditions or

• MOVs with any abnormal characteristics (operational, design, or maintenance conditions)

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 298 of 304 ATTACHMENT 9 Page 5 of 11

<< Technical Position >>

Implementation:

Robinson will exercise high-risk MOVs quarterly, unless they cannot be operated during plant operation; in that case, they will be exercised during refueling (not to exceed 24 months and 6 months grace per ISTA-3170). Robinson uses a 3-tier risk ranking approach developed for implementing the JOG Program(3) and approved by the NRC; thereby satisfying NRC condition 10 CFR 50.55a(b)(3)(ii)(C). The 3-tier approach (high, medium, low) was conservatively reconciled to a 2-tier approach by treating High and Medium risk MOVs as "high-risk" for exercising (i.e. III-3600). Note, the 3-tier approach is used in III-3300 to establish inservice test intervals. See Table 1.

The following "high-risk" MOVs cannot be operated during plant operation and will be exercised during refueling or cold shutdown (not to exceed 24 months and 6 months grace per ISTA-3170).

SI-861A/B SI-862A/B SI-863A/B SI-864A/B V6-16C MOVs in adverse or harsh environmental conditions during normal operation (as defined below) will be exercised quarterly unless they cannot be operated during plant operation; in that case, they will be exercised during refueling (not to exceed 24 months and 6 months grace per ISTA-3170). Note, these criteria were developed based on Engineering judgement and experience because Appendix III does not list specific requirements.

• MOVs in a normal ambient environment >140F A review of RNP's MOVs found that RC-535 and RC-536 (PORV Block Valves) experience ambient environmental temperatures of 175°F (9% of life), 165°F (25% of life), 155°F (66% of life) per HBR2-11260 SH00008 Rev 021 ZONE MAP FOR ENVIRONMENTAL PARAMETERS Note 13. These MOVs will be exercised quarterly. See Table 1.

• Normally open MOVs with flowing system media temperatures greater than 400F A review of RNP's MOVs did not find any MOVs meeting this condition. Note, MS- V1-8A/B/C are in steam service but are normally closed and did not meet the criteria.

• MOVs located outside and not protected/shielded from direct rain A review of RNP's MOVs did not find any MOVs meeting this condition.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 299 of 304 ATTACHMENT 9 Page 6 of 11

<< Technical Position >>

RNP's MOV population was reviewed for abnormal characteristics (operational, design, or maintenance conditions). None were found. The criteria used are shown below and are based on Engineering judgement and experience because Appendix III does not list specific requirements.

• MOVs with reach rod mechanisms

• MOVs with significant negative operating experience that has not been addressed

• MOVs with unique actuator or valve designs will little operating experience

• MOVs that are used or maintained outside of generally accepted methods III-3721 HSSC MOVs HSSC MOVs shall be tested in accordance with para. III-3300 and exercised in accordance with para. III-3600. HSSC MOVs that can be operated during plant operation shall be exercised quarterly, unless the potential increase in core damage frequency (CDF) and large early release (LER) associated with a longer exercise interval is small.

NRC Condition 10 CFR 50.55a(b)(3)(ii)(B)

MOV testing impact on risk. Licensees shall ensure that the potential increase in core damage frequency and large early release frequency acceptably small when extending exercise test intervals for high risk MOVs beyond a quarterly frequency.

Implementation:

High-risk MOVs will be exercised quarterly, unless they cannot be operated during plant operation; in that case, they will be exercised during refueling (not to exceed 24 months and 6 months grace). See III-3620(a) discussed above and Table 1.

NRC Condition 10 CFR 50.55a(3)(2)(D)

When applying Paragraph III-3600, "MOV Exercising Requirements," Licensees shall verify that the stroke time of MOVs specified in plant technical specifications satisfies the assumptions in the plant's safety analyses.

INSERVICE TESTING PROGRAM TMM-004 Rev. 104 Page 300 of 304 ATTACHMENT 9 Page 7 of 11

<< Technical Position >>

Implementation:

A review of technical specifications and plant safety analysis found the following documents with specific stroke times listed for MOVs.

• Containment isolations valves (CIVs) are required to close within 60 seconds per GID/90-181/00/RCI Appendix B Revision 17. SR 3.6.3.4 "Verify the isolation time of each automatic power operated containment isolation valve is within limits."

• Plant Parameter Documents (various cycles, all were reviewed, conservative stroke time results)

• Safety Analysis Inputs Manual

• FSAR section 6.2.1.4.3.2 "The main feedwater pumped flow rate continues until flow is terminated by closure of the block valve 50 seconds after the SI signal."

• Containment Analysis Inputs; RNP-M/MECH-1651 The required stroke time for MOVs receiving an automatic actuation signal is reduced to account for potential momentary motor-stall due to low motor terminal voltage. The amount of potential stall-time is evaluated in the referenced GL89-10 MOV Calculations (motor notes section) and RNP-E-8.042. RNP will stroke time test the following MOVs using the limits specified below.

SI-880D note b < 15 Ref [11]; RNP-M/MECH-1527 motor notes; See note b.

Notes:

a. SI-860A/B and SI-861 A/B are normally closed containment isolation valves and are not required to close in response to an accident, and consequently are not required to close in less than 60 seconds. Therefore, they will not be stroke time tested (ref. GID/90-181/00/RCI Appendix B)

b. SI-880A,B,C,D - The determination of 15 seconds was based on discussions with the preparer and reviewer of RNP-M/MECH-1524,5,6,7. These calculations use transient motor torque values from RNP-E-8.042 in the opening direction. Momentary motor-stalling is not expected when transient values are used.

c. Required "as-tested" stroke time to assure MOV mission time is met. The required stroke time during exercise testing is reduced to account for potential momentary motor-stall due to reduced motor voltage.

The amount of potential stall-time is evaluated in the referenced GL89-10 MOV Calculations (motor notes section) and RNP-E-8.042

d. SI-870A/B, Boron Injection Tank outlet valves, are normally closed and are required to open on an S-Signal. The specified 15 seconds less a possible 5 second stall time is less than the actual stroke time of the valve. Evaluations have been performed (see RNP-M/MECH-1424, 29 motor notes section) to show that the full required flow for High Head Safety Injection can be achieved within the actual stroke time.

Therefore, the maximum 15 second stroke time is appropriate.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 6 of 26 1.0 PURPOSE

1. This procedure describes the methods used to develop, administer, and implement the H. B. Robinson, herein referred to as RNP, Snubber Program Plan for the Sixth 10-Year Interval (02/19/2023 through 02/18/2032).

2.0 SCOPE

1. This plan was developed and prepared to meet the requirements of the American Society of Mechanical Engineers, Operation and Maintenance (OM) of Nuclear Power Plants, 2017. This procedure applies to snubbers in the ASME OM scope, and is subject to the limitations and modifications of 10 CFR 50.55a(b)(3), except the design and access provisions and preservice examination requirements. It identifies those snubbers that are subject to examination and testing.

2. The Program Scope includes the following:

• Snubbers used in systems that perform a specific function in shutting down a reactor to the safe shutdown condition.

• Snubbers used to maintain the safe shutdown condition.

• Snubbers employed to mitigate the consequences of an accident.

• Snubbers used to ensure the integrity of the reactor coolant pressure boundary.

3. In keeping with good engineering practice and to provide reasonable assurance of structural reliability, any remaining snubbers not identified above (typically Non-Safety related) are also included in the program for periodic examination, at a minimum, or otherwise monitored and may be tested as augmented tests not required by the OM scope.

3.0 DEFINITIONS

1. Acceptable: A snubber that has been examined or tested, and is shown to meet examination or testing acceptance criteria.

2. Accessible: Snubbers that can be readily examined or tested during normal plant operations without exposing plant personnel to undue hazards or dose.

3. Defined Test Plan Group (DTPG): Snubbers selected for testing in accordance with the snubber testing sample plan.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 7 of 26 3.0 DEFINITIONS (continued)

4. Degraded: Any snubber that has an examination or testing parameter that is approaching, but has not exceeded the limits of the acceptance criteria.

5. Failure Mode Group (FMG): A group of snubbers that have failed and those other snubbers that have similar potential for similar failure.

6. Fuel Cycle: Time period beginning with the start of the reactor until the completion of the next refuel outage and subsequent restart.

7. Inaccessible: Snubbers that are located in environments which make it impractical for the snubbers to be examined under normal plant operations without exposing plant personnel to undue hazards (e.g., radiation or extreme heat).

8. Operational Readiness Testing: Measurement of the parameters that verify snubber operational readiness.

9. Safety-Significant Snubbers: Snubbers designated as non-safety but determined that their failure or the failure of the system on which they are installed would have an adverse effect on any safety-related system.

10. Service Life: The period of time a snubber is expected to meet the operational readiness requirements without maintenance.

11. Shock Suppressor, Suppressor, Snubber: Hydraulic and mechanical dynamic restraints designed for use on piping systems or equipment which allow unrestrained thermal growth, but provide controlled restraint during dynamic or cyclic disturbances.

12. Unacceptable: Snubbers that do not meet examination or testing requirements.

13. Test Campaign: The series of actions required to complete the testing of DTPG samples for a specific cycle.

14. Test Interval: The period between completed Test campaigns for a given DTPG.

15. Unanticipated Transient Dynamic Event: any unforeseen or unanalyzed event, such as (but not limited to) a steam hammer, water hammer, void collapse, or seismic event greater than design basis.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 15 of 26 5.6 Visual Examination (continued)

3. The visual as-found examination for Safety Related or Safety Significant snubbers shall be performed before the snubber is disconnected or removed for any reason. This examination is to determine that there are no visible indications of damage or impaired functional ability due to physical damage, leakage, corrosion, or degradation from environmental exposure or operating conditions.

4. An augmented scope is invoked whenever a visual examination is to be performed as a supplemental scope, outside of the ASME OM requirements, or is for Non-Safety related snubbers.

5. Any unacceptable, unsatisfactory or degraded snubber condition reported on the applicable inspection/test report sheet, or any noted anomaly identified during the current examination period, shall have an evaluation performed by an individual knowledgeable in snubber operability requirements.

a. This evaluation shall be performed to determine the type and cause of the visual examination discrepancy and effect on the operability of the snubber and related components.

b. If the condition is determined to be generic, then additional examinations may be required, or if an isolated case, a Work Request may be issued to correct any discrepancies found.

c. For any snubber determined to be unacceptable or unsatisfactory, the Snubber Program Manager or designee shall initiate an NCR.

6. Visual examinations may be performed on a schedule based on the number of unacceptable snubbers found during the previous examination interval in accordance with Attachment 1, Visual Examination Intervals.

7. Snubbers with unacceptable visual examination results may be evaluated by performing operational readiness testing (i.e., functional testing) in as-found condition. In accordance with ASME OM Code, Article ISTD-4240, snubbers satisfying operational readiness testing acceptance criteria may be reclassified as acceptable visual examinations.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 16 of 26 5.7 Operational Readiness Testing

1. An Inservice test campaign shall be conducted every fuel cycle.

2. Tests are required to be in accordance with a specified sampling plan.

6. Snubbers shall be tested in their as-found condition regarding the parameters to be tested to the fullest extent practicable.

• Test methods shall not alter the condition of a snubber to the extent that the results do not represent the as-found snubber condition.

• Snubbers may be tested in their installed location or may be removed from the field installation and bench tested in accordance with approved procedures.

• Snubbers shall not be subjected to prior preventive or corrective maintenance (pre-conditioning) specifically for the purpose of meeting the applicable examination or testing requirements. Verification of freedom of motion upon snubber removal is not considered to be pre-conditioning.

7. Snubbers that are maintained or repaired by removing or adjusting a snubber part that can affect the results of the applicable tests required by this program, shall be examined and tested in accordance with the applicable requirements before returning to service. Additionally, the applicable installation requirements shall be met. The requirements selected shall ensure that the parameters that may have been affected are verified to be acceptable by suitable examination and tests.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 17 of 26 5.7 Operational Readiness Testing (continued)

8. The applicable site maintenance procedures shall govern the removal and reinstallation of plant installed snubbers.

9. Each Safety Related or Safety Significant snubber shall have an as-found visual examination performed prior to removal activities and an as-left visual examination following reinstallation in accordance with any applicable site examination or surveillance instruction(s).

• Non-Safety snubber visual examination requirements are directed in PM-142, Non-Safety Related Shock and Sway Suppressor Visual Inspection.

10. For each Safety Related or Safety Significant snubber determined to be unacceptable by operational readiness testing, additional snubbers shall be tested as described by the applicable governing basis requirements.

a. Unacceptable (i.e., failed) snubbers shall be evaluated to determine the cause of the failure and documented in accordance with the Corrective Action Program (NCR). The evaluation shall include review of information related to other unacceptable snubbers found during that test campaign.

b. An Engineering Evaluation shall be performed on the System, Structure, or Component (SSC) to which the failed snubbers were attached.

• The purpose of this Engineering Evaluation will be to determine if the SSC to which the inoperable snubbers are attached were adversely affected by the inoperability of the snubbers in order to ensure that the SSC remains capable of meeting the designed service.

11. For each Non-Safety Related snubber determined to be unacceptable by operational readiness testing, additional samples may be required as determined under the Corrective Action Program by the type of failure and extent of condition as warranted.

12. Degraded snubbers are repaired or replaced as a preventive maintenance action. Failure mode grouping and scope expansion is not required for degraded snubbers unless determined to be required for extent of condition concerns.

Additional snubbers may be tested or replaced at the discretion of Engineering based on the cause of the degradation for service life monitoring purposes.

Information learned from the degraded snubbers shall be considered in the service life monitoring program as applicable.

13. Unacceptable snubbers shall be adjusted, repaired, modified, or replaced.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 18 of 26 5.7 Operational Readiness Testing (continued)

14. Test equipment failure during functional testing may invalidate that day's testing.

Failed testing equipment will be repaired or replaced. If it can be determined exactly when the failure happened, only the affected snubbers shall be retested.

15. Test results will be reviewed for adverse trends which will help establish the service life of specific snubbers or locations.

16. Each snubber in a parallel or multiple-snubber installation shall be identified and counted individually. Fractional sample sizes shall be rounded up to the next integer.

17. Steam Generator snubbers may be tested in-place or by removing and testing subcomponents (control valves) that control the parameters to be verified.

5.8 Defined Test Plan Group (DTPG)

1. The DTPGs shall include all Safety Related or Safety Significant snubbers except replacement snubbers and snubbers repaired or adjusted as a result of not meeting the acceptance requirements, during the previous operating cycle and those which had failed during the previous test interval and are scheduled for testing. These snubbers shall be exempt for the concurrent test interval.

2. Snubbers attached to the steam generator shall be a separate DTPG. There are no snubbers attached to the reactor coolant pump(s).

3. Snubbers placed in the same location as snubbers that failed during the previous test campaign shall be retested at the time of the subsequent test campaign unless the cause of the failure is clearly established and corrected so as to preclude reoccurrence. These snubbers shall not be considered a part of the test campaign sampled DTPG. Failures found by these retests shall not require additional testing but shall be evaluated for appropriate corrective action.

5.9 Testing Sample Plans

1. Safety Related or Safety Significant snubbers of each DTPG shall be tested in accordance with the Test Plan.

2. If the test plan selection has changed since the Plan submittal to the Regulatory Authorities, then it may be necessary that the revised Snubber Program Plan be re-submitted as specified in Section 5.2.

3. The test plan(s) shall be selected for each DTPG before the scheduled testing begins. Test plan(s) selection for each DTPG shall be documented. DTPG's shall not be changed after initiating a test campaign.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 19 of 26 5.9 Testing Sample Plans (continued)

4. The test plan selected for a DTPG shall be used throughout the refueling outage tests for that DTPG and any Failure Mode Group (FMG) that is derived from it.

5. For unacceptable snubber(s), the additional testing shall continue in the DTPG or FMG.

5.10 Testing Sample Plan Selection

1. The Safety Related or Safety Significant Sample Plan for the Defined Test Plan Group (DTPG) functional testing is the 10% Test Plan.

2. The Safety Related or Safety Significant sample may include representation from the DTPG based on the significant features (i.e., the various designs, configurations, operating environments, sizes, and capacities) and based on the ratio of the number of snubbers of each significant feature, to the total number of snubbers in the DTPG.

3. Selection of the representative Safety Related or Safety Significant snubbers may be random, may also be selected from Safety Related or Safety Significant snubbers concurrently scheduled for seal replacement or other similar activity related to service life monitoring. The snubbers shall be tested on a generally rotational basis to coincide with the service life monitoring activity.

4. Currently all snubbers have established service life PM's which coordinate with the snubber functional testing requirements. The number of snubbers scheduled for seal life replacement each outage meets the requirements for the 10% Test Plan. Testing of the population in this manner also tests the oldest snubbers installed.

5. For RNP, snubbers are categorized into three DTPG "types/groups" as follows:

a. Large bore (Enertech/Anker-Holth) snubbers (SG Snubbers 1-12)

[12 total, test 2 (one bank)]

b. Small bore hydraulic units [18 total, test 2]:

(1) Anvil and Grinnell Figure 200/201, 11/2 inch bore (No. 13, 14, 26, 30, 35)

(2) Anvil and Grinnell Figure 200/201, 21/2 inch bore (No. 17 through 25, 28, 29)

(3) Bergen-Paterson HSSA, 31/4 inch bore (No. 15 and 16)

c. Mechanical snubbers (PSA 1/2, No. 33, 34, and 36) [3 total, test 1]

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 20 of 26 5.10 Testing Sample Plan Selection (continued)

6. The test sample plan is completed when the mathematical expression below is satisfied, or all Snubbers have been tested.

a. Testing shall satisfy the following mathematical expressions.

(1) For each DTPG N 0.1n + C(0.1n / 2) where: N = total number of Snubbers tested that were selected from the DTPG n = number of Snubbers in the DTPG C = total number of unacceptable Snubbers found in the DTPG (excluding those counted for FMG tests)

(2) For each FMG:

Nf C f (0.1n / 2) where: Nf = all Snubbers selected and tested from the FMG after the FMG was established from the DTPG Cf = total number of unacceptable Snubbers in the FMG, plus those found in the DTPG and used to establish the FMG n = number of Snubbers in the DTPG 5.11 Sample Expansion

1. After determination that a Safety Related or Safety Significant snubber is unacceptable, an additional test plan sample shall be established. Additional test sample size shall be at least one-half the size of the initial sample from that DTPG.

2. In addition to the required test plan sample expansion an FMG test population may be established. The unacceptable snubber may be categorized into a failure mode group (FMG), containing all unacceptable snubbers that have a given failure and all other snubbers evaluated to be subject to the same failure.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 21 of 26 5.11 Sample Expansion (continued)

3. For the Safety Related/Safety Significant 10% Plan Failures - When an unacceptable Snubber has not been assigned to an FMG, the additional sample shall be taken from the DTPG. As practicable, the additional sample shall include the following:

a. Snubbers of the same manufacturer's design.

b. Snubbers immediately adjacent to those found unacceptable.

c. Snubbers from the same piping system.

d. Snubbers from other piping systems that have similar operating conditions such as temperature, humidity, vibration, and radiation.

e. Snubbers that are previously untested.

5.12 Snubber Replacement

1. Any replacement or modified snubber(s) shall have a proven suitability for the application and environment.

2. Replacement or modified snubbers shall be examined and tested before placing into service. Test results from the manufacturer for new snubbers or from the rebuild vendor may be utilized.

5.13 Snubber Deletion

1. Snubbers may be deleted from the plant based on analysis of the affected piping system. When an unacceptable snubber is subsequently deleted prior to the completion of the test campaign, the deleted snubber shall nevertheless be considered in its respective examination population, examination category or FMG for determining the corrective action.

2. The number of deleted snubbers that failed or passed tests or examinations prior to being deleted will be used in determining examination or testing frequencies.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 22 of 26 5.14 Unanticipated Transient Dynamic Events

1. If an unanticipated transient dynamic event that may affect snubber operational readiness (e.g., water hammer, steam hammer, etc.) occurs and is identified outside the scope of Section 5.6 or Section 5.7, then the affected snubbers and systems shall be reviewed and any appropriate corrective action taken.

2. Event information, scope of review, and actions taken will be documented in Corrective Action Program (NCR).

a. Program Manager will notify System Engineering or Design Engineering to define extent of evaluation for affected system.

b. Snubbers within affected region will be examined, stroked, or tested as deemed appropriate to address concern.

5.15 Service Life Monitoring

1. The object of service life monitoring is to identify service and environmental conditions that can adversely affect snubber performance and to estimate appropriate service life limits for installed snubbers. Service life estimates vary and are generally based on factors such as manufacturer recommendations, design limits, environmental conditions, applications and materials, among others. Service life estimates should be adjusted periodically based on plant experience and technical data to ensure that the snubber(s) operational readiness is achieved throughout its intended installed life. Service life monitoring is required for all Safety Related or Safety Significant snubbers.

Service life monitoring of Non-Safety Related snubbers is not addressed by the ASME OM Code.

2. A record of the service life of each snubber in the program shall be maintained.

The snubber service life record shall include the snubber installed location, manufacturer/model, serial number, installed date, rebuild date or date of manufacture and service life expiration date for each applicable snubber. When snubbers are rebuilt / overhauled or replaced, the service life shall be updated which will provide future statistical bases for consideration of snubber service life.

3. Service life for each location where a snubber is installed shall be reevaluated at least once each fuel cycle.

a. Reevaluation shall be based on examination, maintenance, performance, and operating service life history data associated with representative snubbers that have been in service in the plant, as well as other information related to service life.

b. Completion of this reevaluation shall be documented.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 23 of 26 5.15 Service Life Monitoring (continued)

c. Based on the results of the reevaluation, each snubber's service life shall be increased, decreased, or left unchanged.

4. If the reevaluation indicates that service life will be exceeded before the next scheduled system or plant outage, one of the following actions shall be taken prior to the start of the cycle:

a. The snubber shall be replaced with a snubber for which the service life will not be exceeded before the next scheduled system or plant outage.

b. Technical justification shall be documented for extending the service life to or beyond the next scheduled system or plant outage.

c. The snubber shall be reconditioned such that its service life will be extended to or beyond the next scheduled system or plant outage.

5. All small-bore hydraulic snubbers have their service life artificially set to a value below the maximum value in order to coincide with the requirement to test 10%

of the snubbers every refueling outage. This ensures that the oldest installed snubbers are tested each outage and that they are replaced well before manufacturers recommendations.

6. Service life evaluations of steam generator snubbers, which are tested without applying a load to the piston rod, shall consider the results from periodic monitoring of the following:

a. Particulate, viscosity, and moisture content of one or more samples of hydraulic fluid from the snubbers.

b. Seal integrity of snubber seals per OEM recommendations.

7. If testing is conducted specifically for service life monitoring purposes, the results of such testing do not require testing of additional snubbers.

5.16 Miscellaneous

1. Snubber repair and replacement shall be performed in compliance with AD-EG-ALL-1703, ASME Section XI Repair/Replacement Program Administration. Examples of compliance with AD-EG-ALL-1703, ASME Section XI Repair/Replacement Program Administration, would include repair and replacement of load pins and studs, mounting brackets, pipe clamps, snubbers, and any other hardware.

2. Any maintenance or testing performed by the OEM/vendor shall be documented with the associated EST, including personnel certification, test procedures and calibration sheets and test results, when applicable.

SNUBBER PROGRAM PLAN AD-EG-RNP-1618 Rev. 5 Page 24 of 26 5.16 Miscellaneous (continued)
