71111.22-01 INSPECTION OBJECTIVE 01.01 Verify that surveillance testing (including inservice testing (IST)) activities provide objective evidence that risk- or safety-significant structures, systems, and components (SSCs) remain capable of performing their intended safety functions and maintain their operational readiness consistent with their design and licensing bases (i.e., will operate within safety limits and limiting conditions for operation will be met).

01.02 Verify that testing activities provide objective evidence that FLEX SSCs remain capable of performing their intended functions and maintain their operational readiness consistent with their licensing bases.

71111.22-02 GENERAL GUIDANCE The following table outlines additional inspection guidance for selecting risk- or safety-significant systems.

Mitigating Systems - Identify any mitigating system, credited by the licensee as operable when assessing risk, which is adversely impacted by surveillance testing related failures such as failure to adequately test, failure to meet test criteria or, failure to realign equipment after the surveillance.

Risk Priority Example Focus in areas with potential for common Integrated safeguards testing mode failures.

Emergency diesel start/load testing Select surveillance tests which cross technical disciplines (electrical, mechanical, Battery performance testing instrument and control)

Reactor protection, Reactor Coolant System IST of pumps and valves that perform (RCS) leakage detection, and safety injection important functions in mitigating systems. instrumentation testing (For additional guidance on IST inspection refer to IP 73756, In-service Testing of Safety bus loss of voltage and degraded Pumps and Valves and NUREG-1482, voltage relay testing Guidelines for Inservice Testing at Nuclear Power Plants.) Pumps that provide injection water flow and valves that change position to provide injection water flow to the reactor coolant system.

Barrier Integrity - Identify any containment integrity supporting system, credited by the licensee as operable when assessing risk, which is adversely impacted by surveillance test failures such as failure to adequately test, failure to meet test criteria or failure to realign equipment after the test.

Risk Priority Example Containment isolation valve testing, ventilation/filtration system testing Consider selection of the IST activity based on the component or system performance history (known deficiencies), or if the component or system had recently undergone corrective or preventive maintenance.

Issue Date: 11/20/20 2 71111.22

For sites that have Lead Test Assemblies loaded in operating cores, consider selecting a sample to verify that RCS Specific Activity is within limits. NRC Memorandum titled Clarification of Regulatory Path for Lead Test Assemblies, (ML18323A169) has additional background information.

For AP1000 designs, in addition to safety-related structures, SSCs, focus on systems classified as regulatory treatment of nonsafety systems (RTNSS) of high or intermediate importance, which are used for protecting utilities investment and for preventing and mitigating severe accidents. A list of SSCs classified as RTNSS is in Chapter 16 of the Vogtle Electric Generating Plant (VEGP) Updated Final Safety Analysis Report (UFSAR), Table 16.3-1. The list of Risk-Significant SSCs within the Scope of Design Reliability Program, which evaluates the design of the AP1000 and identifies the aspects of plant operation, maintenance, and performance monitoring pertinent to risk-significant SSCs, is in Chapter 17 of the VEGP UFSAR, Table 17.4-

1. RTNSS is discussed in Section C.IV.9 Regulatory Treatment of Nonsafety Systems of Regulatory Guide 1.206, Applications for Nuclear Power Plants.

During plant outages, sample selection should focus on infrequent surveillance tests, and particularly large-scale actuation tests and full-flow engineered safety feature pump testing, as well as inspections of normally inaccessible SSCs (e.g., containment sump inspections, refueling water storage tank or condensate storage tank internal inspections).

As part of the sample, consider reviewing surveillance tests in which there was a modification of the surveillance frequency in accordance with the Risk Management Technical Specification (TS) Initiative 5b Surveillance Frequency Control Program.

For plants that have implemented the requirements of 10 CFR 50.69, sample selection should include consideration of SSCs that have been categorized as RISC-2, nonsafety-related SSCs that perform safety significant functions. Refer to inspection procedure (IP) 37060, 10 CFR 50.69 Risk-Informed Categorization and Treatment of Structures, Systems, and Components Inspection for additional information.

After Fukushima, the NRC ordered every U.S. commercial reactor to have mitigation strategies for dealing with the long-term loss of normal safety systems following the occurrence of a beyond-design-basis external event (NRC Order EA-12-049, ML12054A735). Because of the low probability of an external event causing a simultaneous loss of all AC and normal access to the ultimate heat sink, FLEX equipment may not be risk/safety significant. However, FLEX increases defense-in-depth for beyond-design-basis scenarios to address loss of power and loss of the ultimate heat sink occurring simultaneously at all units on a site.

Implementation guidance for FLEX is found in Nuclear Energy Institute (NEI) 12-06, Diverse and Flexible Coping Strategies (FLEX) Implementation Guide, and endorsed via Japan Lessons Learned Project Directorate Interim Staff Guidance (JLD-ISG) 2012-01, Compliance with Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events. Various revisions are in effect. NEI 12-06, Revision 0 (ML12242A378) is endorsed via JLD-ISG 2012-01, Revision 0 (ML12229A174).

NEI 12-06, Revision 2 (ML15348A015) is endorsed via JLD-ISG 2012-01, Revision 1 (ML15357A163). NEI 12-06, Revision 4 (ML16354B421) is endorsed via JLD-ISG 2012-01, Revision 2 (ML17005A188). It should be noted that not all revisions of NEI 12-06 are endorsed.

Verification of activities under this procedure should focus on performance-based field observations of complete surveillance / testing evolutions, followed by verification of the bases and of the proper demonstration of performance that supports operability / functionality determinations.

Issue Date: 11/20/20 3 71111.22

For each sample, conduct a routine review of problem identification and resolution activities using IP 71152, Problem Identification and Resolution. Examples of significant surveillance testing problems and appropriate inspector follow-up include:

a. Licensee actions to addressed measuring and test equipment (M&TE) that fails calibration. Inspectors should assess the adequacy of the licensees corrective actions, considering the following: the licensee tracks which surveillance tests used each piece of M&TE, compares the failed M&TE calibration information to each surveillance test that used that M&TE, and then assesses the impact to the operability of the affected system. Inspectors should also consider performing a 71111.15, Operability Determinations and Functionality Assessments, sample to more thoroughly assess the potential effects on operability.

b. Licensee actions to address degraded system performance identified during in-service testing. When degraded performance is revealed, inspectors should review the condition reporting data base to determine if the licensee is implementing appropriate corrective actions, such as testing with increased frequency in accordance with American Society of Mechanical Engineers (ASME) Code, Surveillance Frequency Control Program, or other applicable requirements.

71111.22-03 INSPECTION SAMPLES 03.01 Surveillance Test Verify by witnessing surveillance tests and/or reviewing the test data, that surveillance testing activities and results provide objective evidence that the affected SSCs remain capable of performing their intended safety functions (under conditions as close as practical to design bases conditions or as required by TS) and maintain their operational readiness consistent with the facilitys current licensing basis.

Specific Guidance Significant surveillance test attributes for consideration include the following:

1. Effect of testing on plant operations has been adequately addressed by licensee (control room and/or engineering) personnel.

2. Preconditioning of SSCs prior to or post-testing. Unacceptable preconditioning is defined as the alteration; variation; manipulation; or adjustment of the physical condition of an SSC before or during TS surveillance or ASME Code testing such that it will alter one or more of SSCs operational parameters, which results in acceptable test results. Such changes could mask the actual as-found condition of the SSC and possibly result in an inability to verify the operability of the SSC. In addition, preconditioning could make it difficult to determine whether the SSC would perform its intended function during a design basis event in which the SSC might be needed (See Inspection Manual Part 9900, Technical Guidance, Maintenance -

Preconditioning of Structures, Systems, and Components Before Determining Operability, for additional guidance).

Issue Date: 11/20/20 4 71111.22

3. Acceptance criteria are clearly derived from the supporting technical bases (design bases, setpoint calculations, UFSAR, TS Bases, etc.) and demonstrate operational readiness consistent with the facilitys current licensing basis.

4. M&TE specified in procedures are part of the measuring and test equipment program, their calibration status is within acceptable limits, and their range and accuracy are consistent with the application as supported by design bases documents. Plant equipment calibration is correct, accurate, properly documented and the calibration frequency is in accordance with TS, UFSAR, licensee procedures and commitments.

5. Test is performed in sequence and in accordance with written procedure.

6. Jumpers installed or leads lifted during testing are properly controlled.

7. Electrical connections are properly torqued, secure, and maintain their intended design function.

8. For cases where the licensee relies on multiple surveillance tests to satisfy a surveillance requirement, the affected surveillance test procedures collectively accomplish the entire scope of the surveillance requirement.

9. Setpoints, required test accuracy, test frequency, and allowable setpoint drift for selected safety-related instrumentation and control surveillance tests (i.e., RPS, NIs, etc.) conform to applicable setpoint calculations. Reference setpoint data has been accurately incorporated into the applicable test procedure(s).

10. Annunciator and other alarms are demonstrated to be functional and setpoints are consistent with design bases documents. Alarm response procedure entry points and actions are consistent with plant design/licensing bases documents.

11. Testing methods, acceptance criteria, and required corrective actions for IST activities meet with the applicable version of the ASME Code,Section XI. In concert with TS requirements, IST programs are intended to ensure the operational readiness of certain safety-related pumps and valves. Inspectors must review reference values or changes to reference values for consistency with the design bases and verify that the current acceptance criteria match the most recent reference test data. For pump testing, the inspectors should verify that the licensee established system operating conditions that reflect limiting operational conditions and are sufficiently repeatable to allow performance trending. Inspectors should also review sufficient test performance history to verify that the licensee identified and is addressing any adverse trends.

12. For local leak rate testing, isolation valves inside and outside containment are each tested with pressure exerted in a direction consistent with expected accident conditions. The inspectors should verify that the licensee updates the total containment leak rate data with the new measured value and confirm that the overall leak rate is still within acceptable limits. The inspectors should verify that the licensee schedules the isolation valve(s) for maintenance if administrative limits are exceeded. The inspectors should also verify that the containment penetration(s) is declared inoperable if acceptance criteria are exceeded.

Issue Date: 11/20/20 5 71111.22

13. Test frequency was adequate to demonstrate operability (meets TS requirements),

and reliability. Appendix A, Risk Management TS Initiative 5b Surveillance Frequency Control Program, provides additional guidance if a selected sample is associated with the application of the Risk Management TS Initiative 5b Surveillance Frequency Control Program.

14. If an adverse trend in RCS leakage is being monitored by the licensee, the inspectors should verify that the licensee has programs and processes in place to (1) monitor plant-specific instrumentation that could indicate potential RCS leakage, (2) meet existing requirements related to degraded or inoperable leakage detection instruments, (3) use an inventory balance check when there is unidentified leakage (4) take appropriate corrective action for adverse trends in unidentified leak rates, and (5) pay particular attention to changes in unidentified leakage. [C1]

15. Unavailability of the tested equipment is appropriately considered in the licensees Mitigating System Performance Index data.

16. After completion of testing, equipment is returned to the positions/status required for the SSCs to perform its intended safety function.

17. Test equipment is removed after testing.

18. Test data is complete, verified, and meets procedure requirements.

19. For test results that do not meet the acceptance criteria, the results of licensee engineering evaluations provide an acceptable bases for returning affected SSCs to an operable status.

20. Performance trends for the last several completed tests are appropriately documented and addressed. If testing indicates unacceptable setpoint drift or otherwise demonstrates degradation, the inspector must assess the adequacy of the licensees corrective actions. These may include component replacement and/or increased frequency of testing, for example.

03.02 FLEX Testing Verify by witnessing tests and/or reviewing the test data, that testing activities and results provide objective evidence that FLEX SSCs remain capable of performing their intended functions (under conditions as close as practical to licensing conditions) and maintain their operational readiness consistent with the facilitys current licensing basis.

Specific Guidance Section 11.5 of NEI 12-06 contains guidance on FLEX maintenance and testing. If needed, questions regarding FLEX issues can be raised with either the regional Technical Support Branch Chief or with the NRR Beyond Design Basis Engineering Branch (via the NRR DORL PM).

APPENDIX A RISK MANAGEMENT TECHNICAL SPECIFICATIONS (TS) INITIATIVE 5b SURVEILLANCE FREQUENCY CONTROL PROGRAM (SFCP) GUIDANCE 71111.22A-01 INSPECTION OBJECTIVE The objective of this Appendix is to provide additional guidance if a selected sample is associated with a licensees implementation of the risk management TS (RMTS) Initiative 5b, described in the RMTS Guidelines Document NEI 04-10, Risk Informed Method for Control of Surveillance Frequencies.

71111.22A-02 GENERAL GUIDANCE A highlight of the SFCP change process is found in the specific guidance below. The SFCP change process does allow for extending Surveillance Test Intervals (STIs) even when SSCs have had prior failures. However, focus should be placed on previous SSC performance.

The surveillance frequency should be adequate to demonstrate operability. As indicated in Surveillance Requirement (SR) 3.0.1, SRs shall be met during the Modes or other specified conditions in the Applicability for individual Limited Conditions for Operations, unless otherwise stated in the SR. A Surveillance is met only when the acceptance criteria are satisfied. Known failure of the requirements of a Surveillance, even without a Surveillance specifically being performed, constitutes a Surveillance not met. Given an SSCs previous performance, the Surveillance will still need to be met during the extended STI. Any concerns associated with extending STIs given prior SSC performance can be raised with NRR/DRO/IRIB.

71111.22A-03 INSPECTION SAMPLES See Section 03.01 of IP 71111.22.

Specific Guidance:

The following guidance highlights the SFCP change process, as recommended in NEI 04-10, Risk-Informed Technical Specifications Initiative 5b, Risk Informed Method for Control of Surveillance Frequencies, Industry Guidance Document (see list of References for the applicable revision).

If the STI was previously extended through the SFCP, a minimum number of surveillance intervals is needed per the NEI guidance prior to further extending the STI. A minimum of three successive satisfactory performances of the surveillance is needed when the STI is less than or equal to six months, and a minimum of two successive satisfactory performances of the surveillance is needed when the STI is greater than six months.

Surveillance frequency change was evaluated by the licensee for prohibitive commitments, and either no such commitments existed, or they were revised prior to implementation of the STI change.

The qualitative evaluation by the licensee included, as a minimum, the items identified in NEI 04-10, step 7. Some of the items identified include considerations for SSC performance history, Issue Date: 11/20/20 AppA-1 71111.22

vendor specified maintenance frequency, and test intervals specified in applicable industry codes and standards.

If the affected component or system is modeled in the PRA, or was added to the PRA model to support application of the SFCP: The acceptance criteria for licensees evaluation, using the licensee's PRA model, is <1 E-6 CDF and <1 E-7 LERF. If the affected component or system is not modeled in the PRA: The acceptance criteria for the licensees qualitative or bounding analyses is the acceptance criteria of <1 E-7 CDF and <1 E-8 LERF. The acceptance criteria for the cumulative impact of all STI changes is <1 E-5 CDF and <1 E-6 LERF. Sensitivity studies associated with the revised STI are performed by the licensee. An in-depth review of the licensees PRA evaluation or analysis is not required.

An Independent Decisionmaking Panel (IDP) approves the STI change. The IDP is comprised of the site Maintenance Rule Expert Panel, a Surveillance Test Coordinator, and a Subject Matter Expert. If approved, the STI changes are appropriately implemented by revising plant procedures and affected documents, and training personnel as needed. SSC performance associated with the revised STI is also monitored by the licensee. SSC performance is considered during periodic re-assessments.
