1.0 INTRODUCTION

This 1ST Plan has been prepared for Braidwood Station Unit 1 and Unit 2. Both Units are Westinghouse Pressurized Water Reactor Nuclear Plant, with a generation of approximately 1242 MWe for Unit 1 and 1210 MWe for Unit 2. Both Braidwood Unit 1 and Unit 2 are licensed as a hot shutdown plant.

The Braidwood Station Unit 1 and Unit 2 are in their fourth 10 year Interval; the Code of Record for Braidwood is ASME OM Code 2012 Edition. The Interval started on July 29, 2018 and will end on July 28, 2028.

1.1 Purpose To provide requirements for the performance and administration of assessing the operational readiness of those pumps and valves whose specific functions are required to:

• Shutdown the reactor to the safe shutdown condition,

• Maintaining the safe shutdown condition, or

• To mitigate the consequences of an accident.

Non-ASME components may be included as "augmented" components within the 1ST Program.

1.2 Scope All references to the ASME OM Code within this document are intended to apply to the 2012 Code Edition. The program plan was prepared to meet the requirements of the following:

• Subsections of the American Society of Mechanical Engineers (ASME) Code for Operation and Maintenance of Nuclear Power Plants, 2012 Edition as follows:

• ASME OM Code, Subsection 1STA, "General Requirements" ISTA contains the requirements directly applicable to inservice testing including the Owner's Responsibility and Records Requirements.

• ASME OM Code, Subsection ISTB, "Inservice Testing of Pumps in Light-Water Reactor Nuclear Power Plants Pre-2000 Plants" ISTB establishes the requirements for inservice testing of pumps in light-water reactor nuclear power plants. The pumps covered are those provided with an emergency power source, that are required in the shutting down the reactor to the safe shutdown condition, in maintaining the safe shutdown condition, or in mitigation of the consequences of an accident.

• ASME OM Code, Subsection ISTC, "Inservice Testing of Valves in Light-Water Reactor Nuclear Power Plants" Revision Date: November 25, 2020 IST-BRW-PLAN

ISTC establishes the requirements for inservice testing of valves in light-water reactor nuclear power plants. The valves covered include those that are required to perform a specific function, either active or passive, in shutting down a reactor to the safe shutdown condition, in maintaining the safe shutdown condition, or in mitigating the consequences of an accident. Valves that provide overpressure protection to systems or portions of system that are required to perform any of these functions are also included.

• ASME OM Code, Division I, Mandatory Appendix I, "Inservice Testing of Pressure Relief Devices in Light-Water Reactor Nuclear Power Plants" Appendix I provides the requirements for performance testing and monitoring of nuclear plant pressure relief devices. Methods, intervals, and record requirements for monitoring and testing are established, as well as requirements for the evaluation of results.

• ASME OM Code, Division I, Mandatory Appendix II, "Check Valve Condition Monitoring Program" Appendix II provides an alternative to the check valve testing or examination requirements of ISTC-3510, ISTC-3520, ISTC-3530, ISTC-3550, and ISTC-5221.

The purpose of this program is both to improve valve performance and to optimize testing, examination, and preventive maintenance activities in order to maintain the continued acceptable performance of a select group of check valves.

• ASME OM Code, Division I, Mandatory Appendix III, "Preservice and Inservice Testing of Active Electric Motor Operated Valve Assemblies in Light-Water Reactor Power Plants" Appendix III establishes the requirements for inservice testing to assess the operational readiness of active motor-operated valves (MOY s) in light-water reactor (L WR) power plants.

• ASME OM Code, Division I, Mandatory Appendix V, "Pump Periodic Verification Test Program" Appendix V establishes the requirements for implementing a pump periodic verification test. As discussed in ISTB-1400, the Owner shall establish a pump periodic verification test program for certain applicable pumps that are tested in accordance with para. ISTA-1100.

• Additionally, ASME OM Code Cases that have been approved for use by the NRC per Regulatory Guide 1.192 and are adopted for use at Braidwood (subject to additional NRC approval where required) are identified below. These Code Cases Revision Date: November 25, 2020 IST-BRW-PLAN

shall be used during the fourth 10-Year Interval 1ST Program implementation with all conditions, as applicable:

• Code Case OMN-20, "lnservice Test Frequency," Revision 0.

During the Third 1ST 10-Year Interval, OMN-20 was authorized for use by the USNRC per Agency wide Documents Access and Management System (ADAMS)

No. ML17046A286, dated February 21, 2017.

On August 17, 2017 the NRC added a new condition as § 50.55a(b)(3)(x), "ASME OM Code Case OMN-20," to allow licensees to implement OM Code Case OMN-20, "Inservice Test Frequency," in the OM Code, 2012 Edition. This condition allows voluntary action initiated by the licensee to use the code case and is, therefore, not a backfit.

• Code Case OMN-26, "Alternate Risk-Informed and Margin Based Rules for Inservice Testing of Motor Operated Valves."

OMN-26 was authorized for use via approved Code Case by the USNRC. See SER (ADAMS # ML20232A171) dated September 1, 2020.

The Braidwood Nuclear Power Station Pump and Valve Inservice Testing Plan will be in effect through the fourth 120-month interval.

• Unit One: July, 29, 2018 through July 28, 2028

• Unit Two: July 29, 2018 through July 28, 2028

• This plan will be updated as required in accordance with 10 CFR50.55a(f).

The Braidwood Nuclear Power Station Inservice Testing Basis Document includes the justification for inclusion of components in the scope of 1ST and also the justifications for exclusion from the program. Administrative procedures, surveillance testing procedures, and other records required to define and execute the Inservice Testing Program are all retained and available at Braidwood Nuclear Power Station.

3.0 INSERVICE TESTING PLAN FOR VALVES

3. I Valve Inservice Testing Plan Description The Inservice Testing Plan for Valves documents compliance with the requirements of Subsection ISTC of the ASME OM Code except where relief has been granted by the NRC.

Relief requests are provided in Attachment 5.

Where the quarterly exercise testing requirement for various valves have been determined to be impracticable, Cold Shutdown or Refuel Outage Justifications have been identified and written. These justifications are provided in Attachments 9 and 11 respectively.

3.1.1 Supplemental Position Indication On August 17, 2017, the Code of Federal Regulations was updated with a mandatory condition which emphasizes the critical nature of ensuring effective monitoring of valve obturator position and operational readiness as an integral part of performing ISTC-3700 testing. Mandatory Condition 12 for licensees intending to adopt the 2012 edition of the ASME OM Code reads as follows:

"(xi) OM condition: Valve Position Indication. When implementing paragraph ISTC-3700, "Position Verification Testing," in the ASME OM Code, 2012 Edition through the latest edition and addenda of the ASME OM Code incorporated by reference in paragraph (a}{l}{iv) of this section, licensees shall verify that valve operation is accurately indicated by supplementing valve position indicating lights with other indications, such as flow meters or other suitable instrumentation to provide assurance of proper obturotor position for valves with remote position indication within the scope of Subsection ISTC including its mandatory appendices and their verification methods and frequencies."

In response to this new requirement, the Braidwood 1ST Program has identified, and in some cases developed, methods to verify valve obturator position is accurately indicated. The listing of the methodology used to verify Supplemental Position Indication (SPI) compliance for the applicable valves is maintained in the valve basis documentation.

Proposed Alternative to Utilize Code Case OMN-26 Attachment 1 Response to Request for Information Page 1 of 2 Response to NRC Staff's Request for Additional Information By application dated January 31, 2020 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML20034C819), Exelon Generation Company, LLC (Exelon) submitted a request in accordance with paragraph 50.55a(z)(1) of Title 10 of the Code of Federal Regulations (10 CFR) for a proposed alternative to the requirements of 10 CFR 50.55a and the American Society of Mechanical Engineers (ASME) Code for Operation and Maintenance of Nuclear Power Plants (OM Code) at Braidwood Station, Units 1 and 2, Calvert Cliffs Nuclear Power Plant, Units 1 and 2, Clinton Power Station, Unit No. 1, R.E. Ginna Nuclear Power Plant, Limerick Generating Station, Units 1 and 2, Nine Mile Point Nuclear Station, Units 1 and 2, and Peach Bottom Atomic Power Station, Units 2 and 3. The proposed alternative would provide a Risk-Margin based methodology that establishes limitations for maximum inservice test intervals for Motor Operated Valves (MOVs).

In an email dated June 1, 2020, from the NRC (Joel Wiebe) to Exelon (David Neff) (ADAMS Accession No. ML20153A704), the NRC provided a draft Request for Additional Information (RAI) seeking clarification of certain issues related to the RAI. A clarification call was conducted on June 8, 2020, with representatives from Exelon and the NRC where the draft RAI text was confirmed with no changes. Exelon agreed to provide the response to the RAI within 30 days of June 8, 2020. The response to the RAI is provided below. A revised version of the subject Relief Request is provided in Attachment 2 with changes highlighted based on the RAI response provided below.

In its submittal dated January 31, 2020, Exelon is requesting the implementation of American Society of Mechanical Engineers (ASME) Code Case OMN-26, "Alternate Risk-Informed and Margin Based Rules for lnservice Testing of Motor Operated Valves," for the diagnostic testing intervals for active motor-operated valves (MOVs) as an alternative to the provisions in ASME Operation and Maintenance of Nuclear Power Plants, Division 1, OM Code: Section 1ST (OM Code), 2012 Edition, Mandatory Appendix Ill, "Preservice and lnservice Testing of Active Electric Motor Operated Valve Assemblies in Light-Water Reactor Power Plants," as incorporated by reference in 10 CFR 50.55a, in accordance with 10 CFR 50.55a(z)(1 ). Code Case OMN-26 provides separate tables with notes for the diagnostic test intervals for the High Safety Significant Component (HSSC) MOVs and Low Safety Significant Component (LSSC)

MOVs. In its submittal, Exelon has combined the OMN-26 tables into one table. It is not clear that the table in the Exelon submittal has accurately included all of the provisions specified in OMN-26 to allow the extended diagnostic test intervals. For example, the HSSC and LSSC tables in OMN-26 specify that to implement the extended diagnostic test intervals allowed in the code case, an MOV must be routinely operated at Design Basis Pressure Conditions with Note (A) in the OMN-26 tables specifying that this routine operation occurs at a periodicity no less frequent than once a refueling outage. The Exelon submittal as detailed in the proposed Exelon table does not appear to include these OMN-26 provisions. Exelon is requested to justify that all of the provisions in both of the OMN-26 tables have been accurately combined into the single table in its submittal, or specify in its submittal that the actual OMN-26 tables will be implemented.

Proposed Alternative to Utilize Code Case OMN-26 Attachment 1 Response to Request for Information Page 2 of 2

RESPONSE

Exelon will implement the relief request (RR) in compliance with Code Case OMN-26 in its entirety, including all tables and associated notes. A complete review of the RR submittal versus the Code Case OMN-26 was performed and identified that all of the provisions in the code case were included in the RR submittal except for Notes A and D. Notes A and D were omitted from the RR submittal as both the design basis stroking frequency (Note A) and the inservice test intervals (Note D) are deemed to be covered by existing processes and procedures at Exelon. Minor editorial changes are also made to Notes 6 and 7 to align with the language in the corresponding OMN-26 Table notes.

In order to incorporate Code Case OMN-26 Note A from Tables 1 and 2, Note 6 of the Exelon Table in the RR submittal is revised as follows to include all the text in Note A. A clarification is added regarding the routine stroking of MOVs during normal operations. A second clarification is added regarding the periodicity of test strokes; once a refueling outage is replaced with once a refueling cycle. The stations included in this relief request are on either an 18- or a 24-month refueling cycle. The Code Case OMN-26 Note A language unnecessarily restricts the test strokes to occur during a refueling outage. Changes are shown with revision markers.

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 outage cycle, must be in the applicable safety function direction(s), and the MOV aR-G must have no k-RewH applicable operating experience, degradation or diagnostic test anomaly with the potential for adverse that potentially impacts 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.

In order to incorporate editorial changes, Note 7 is revised as follows with revision markers.

7. Operating plants that have acquired the requisite test data to satisfy Appendix Ill, paragraphs lll-3310(b) or Ill 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.

In order to incorporate Code Case OMN-26 Note D from Tables 1 and 2, a new Note 8 to the Exelon Table in the RR submittal is added as follows to include all the text in Note D. A clarification is added regarding .the inservice test interval for MOVs.

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. The inservice test interval is uniquely established for each MOV based on margin and risk classification of the MOV.

Relief Request to Utilize Code Case OMN-26, Revision 1

4. Reason for Request

In accordance with 10 CFR 50.55a(z)(1 ), Exelon Generation Company, LLC (Exelon) is requesting approval to adopt ASME OM Code Case OMN-26 in conjunction with implementing Mandatory Appendix Ill for all Exelon plants identified in Section 2.

Code Case OMN-26 better aligns OM Code 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. The Appendix Ill ten-year maximum inservice test interval was originally established to align with the maximum test interval allowed under the Generic Letter 96-05 MOV Programs that, for most Licensees, was established by the Joint Owners Group (JOG) MOV Periodic Verification Program. There is no formal technical basis for the current Appendix Ill ten-year maximum interval that applies to all MOVs regardless of Risk and Margin. Over the past twenty years, Exelon MOV Programs have demonstrated many margin stable MOVs that can be readily justified to extend from their current MOV Program maximum inservice test intervals of six years (for High Risk) and ten years (for Low Risk).

5. Proposed Alternative and Basis for Use

Proposed Alternative:

Exelon 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 111-3310 (c) The maximum inservice test interval shall not exceed 1O years unless Risk Informed lnservice Testing applies under the provisions of para. 111-3700. MOV inservice tests conducted per para. 111-3400 may be used to satisfy this requirement.

Proposed Alternative to 111-3700 Risk-informed MOV inservice testing that incorporate risk insights in conjunction with MOV Functional Margin to establish MOV grouping, acceptance criteria, exercising requirements and test interval may be implemented.

Proposed Alternative to 111-3721 111-3721 HSSC MOVs. HSSC MOVs shall be tested in accordance with para. 111-3300 and exercised in accordance with para. 111-3600 while applying the following HSSC MOV Risk insights and limitations:

(a) 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.

(b) For HSSC MOVs, the maximum inservice test interval shall be established in accordance with Table 1 of OMN-26 (see below)

Relief Request to Utilize Code Case OMN-26, Revision 1 OMN-26 Table 2 Notes:

(A) Occurs at a periodicity no less frequent than once a refueling outage.

(B) To utilize these intervals, test strokes at or exceeding design basis system conditions must be in the applicable safety function direction(s) and 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.

(C) Operating plants that have acquired the requisite test data to satisfy Appendix Ill, paragraphs 111-331 0(b) or lll-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.

(D) For the purpose of this code case, the MOV functional margin limits apply to the As-Left MOV condition at the start of the inservice test interval and include applicable test uncertainties and allowance for service- related degradation.

Basis for Use:

The requested relief to adopt OMN-26 is in line with the current JOG MOV Periodic Verification Test Program that Exelon has implemented since the late 1990's 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 over more than 25 years of MOV Performance Verification Testing. Appendix Ill alone, in isolation 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. Exelon'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 Exelon's desire to adopt a divisional MOV outage testing strategy that reduces the implementation burden of MOV lnservice 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 Ill from ten years to nine years Page 4 of 7

EXELON GENERATION COMPANY, LLC 1ST PROGRAM - RELIEF REQUEST Proposed Alternative in Accordance with 10 CFR 50.55a(z)(1)

Relief Request to Utilize Code Case OMN-26, Revision 1 commensurate with Risk Informed Methodology. Further under this relief request, Exelon 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 lnservice test interval to 12 Years for Very High Margin HSSC MO Vs and 16 years for Very High Margin Low Safety Significant Component (LSSC) MOVs.

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 lnservice 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 Ill. 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 each Exelon station 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)

The Table below provides a detailed comparison of the Maximum MOV Test Intervals for the JOG MOV Program, Mandatory Appendix Ill and Code Case OMN-26 that Exelon seeks to adopt via this relief request. MOVs identified with Bold type have maximum MOV inservice test intervals exceeding the current Appendix Ill ten-year limit.

1. Code Case Maximum lnservice Test Intervals for all Low/Medium Margin MOVs are less than or equal to current ten-year Appendix Ill limit. (i.e., Code Case is more conservative than Appendix Ill for Low/Medium Margin MOVs).

2. Code Case Maximum lnservice Test Intervals for Low/Medium Margin HSSC MOVs are equal to the current JOG MOV PV Program limits of two/four years respectively. (Code Case intervals are aligned with JOG MOV).

3. Code Case Maximum lnservice Test Intervals for Low/Medium Margin LSSC MOVs (four/nine years) are less than the current JOG MOV PV Program limits of six/ten years respectively.

4. The following four categories of MOVs have maximum inservice test intervals that exceed the current ten-year limit:

a. High Margin, LSSC MOVs. (12 Years)

b. Very High Margin, HSSC MOVs that are periodically stroked at design basis DP conditions (DBDPT) (12 Years)

c. Medium Margin, LSSC MOVs that are periodically DBDPT (12 Years)

5. Except for Low Margin HSSC MOVs, the Maximum MOV lnservice 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.

2.0 REGULATORY EVALUATION

The NRC regulations in 10 CFR 50.55a(f), "lnservice Testing Requirements," require, in part, that 1ST of certain ASME Code Class 1, 2, and 3 components must meet the requirements of the ASME OM Code and applicable addenda, except where alternatives have been authorized pursuant to paragraph 10 CFR 50.55a(z)(1) or 10 CFR 50.55a(z)(2).

In proposing alternatives, a licensee must demonstrate that the proposed alternatives provide an acceptable level of quality and safety (10 CFR 50.55a(z)(1)) or compliance would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety (1 O CFR 50.55a(z)(2)).

3.0.1 Applicable ASME OM Code The following request is an alternative test plan in lieu of certain 1ST requirements of the 2012 Edition of the ASME OM Code for the 1ST programs at the plants listed in Table 1 of this safety evaluation (SE) for the duration of their current 10-year 1ST program interval.

3.1.1 Licensee's Alternative Request ASME OM Code Requirements:

Mandatory Appendix Ill, "Preservice and lnservice Testing of Active Electric Motor Operated Valve Assemblies in Light-Water Reactor Power Plants," paragraph 111-3310, "lnservice Test Interval," subparagraph (c) states, in part, that "The maximum inservice test interval shall not exceed 10 yr."

Mandatory Appendix Ill, paragraph 111-3700, "Risk-Informed MOV lnservice Testing," states that "Risk-informed MOV inservice testing that incorporates risk insights in conjunction with performance margin to establish MOV grouping, acceptance criteria, exercising requirements and testing interval may be implemented."

Mandatory Appendix Ill, paragraph 111-3721, "[High Safety Significant Component] HSSC MOVs," states that "HSSC MOVs shall be tested in accordance with para. 111-3300 and exercised in accordance with para. 111-3600. 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."

Mandatory Appendix Ill, paragraph 111-3722, "[Low Safety Significant Component] LSSC MOVs,"

subparagraph (d), states that "LSSC MOVs shall be inservice tested at least every 1O yr in accordance with para. 111-3310."

Alternative testing is requested for safety-related MOVs that are currently required to meet these ASME OM Code requirements.

The licensee states, in part:

Reason for Request

Code Case OMN-26 better aligns OM Code 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. The Appendix Ill ten-year maximum inservice test interval was originally established to align with the maximum test interval allowed under the Generic Letter 96-05 MOV Programs that, for most Licensees, was established by the Joint Owners Group (JOG) MOV Periodic Verification Program.

There is no formal technical basis for the current Appendix Ill ten-year maximum interval that applies to all MO Vs regardless of Risk and Margin. Over the past twenty years, Exelon MOV Programs have demonstrated many margin stable MOVs that can be readily justified to extend from their current MOV Program maximum inservice test intervals of six years (for High Risk) and ten years (for Low Risk).

Proposed Alternative Exelon proposes to implement the ASME OM Code Case OMN-26 alternative risk and margin informed rules for inservice testing of MOVs in its entirety.

HSSC MOVs shall be tested in accordance with para. 111-3300 and exercised in accordance with para. 111-3600 while applying the following HSSC MOV risk insights and limitations:

(a) 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.

(b) For HSSC MOVs, the maximum inservice test interval shall be established in accordance with Table 1 of OMN-26 OMN Table 1 HSSC MOV - Margin Based Maximum lnservice Test Intervals HSSC MOV Functional Maximum lnservice If MOV is routinely(A) operated at Margin< 0 J Test Interval (Years) Design Basis Pressure Conditions

(B) To utilize these intervals, test strokes at or exceeding design basis system conditions must be in the applicable safety function direction(s) and 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.

(D) For the purpose of this code case, the MOV functional margin limits apply to the As-Left MOV conditions at the start of the inservice test interval and include applicable test uncertainties and allowance for service-related degradation.

Basis for Use In its letters dated January 31 and July 6, 2020, the licensee describes the basis for its proposed alternative to implement ASME OM Code Case OMN-26 for the nuclear power plants listed in Table 1 of this SE. In summary, the licensee considers the requested alternative to adopt OMN-26 to be in line with the current JOG MOV periodic verification test program that Exelon has implemented since the late 1990's in response to Generic Letter(GL) 96-05. Both the JOG MOV periodic verification program and Code Case OMN-26 provide a risk-margin based methodology that establishes limitations for maximum 1ST intervals for MOVs. The licensee considers Code Case OMN-26 to provide a reasonable extension of this risk-Informed philosophy based on the lessons learned and accumulated MOV performance data gathered over more than 25 years of MOV performance verification testing. The licensee states that Appendix Ill alone, in isolation from Code Case OMN-26, provides no such methodology other than a maximum limit for the 1ST interval regardless of risk or margin.

In its letter dated July 6, 2020, the licensee clarifies the implementation of Code Case OMN-26 to be consistent with its plant operations. For example, the licensee states that to implement to extended intervals with MOV design-basis differential pressure testing, test strokes at or exceeding design basis system conditions must occur at a periodicity no less frequent than once a refueling cycle 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. The licensee notes that these routine strokes during the 1ST interval are not required to be diagnostically monitored. The licensee also states that the MOV functional margin limits apply to the As-Left MOV condition at the start of the 1ST interval and includes applicable test uncertainties and allowance for service-related degradation. The licensee notes that the 1ST interval is uniquely established for each MOV based on margin and risk classification of the MOV.

3.1.2 NRC Staff Evaluation The NRC regulations in 10 CFR 50.55a(b)(3)(ii) require nuclear power plant licensees to comply with the provisions of the ASME OM Code incorporated by reference in 10 CFR 50.55a, and must establish a program to ensure that MOVs continue to be capable of performing their design-basis safety function. The NRC staff considers ASME OM Code testing specified in Mandatory Appendix Ill with the conditions in 10 CFR 50.55a(b)(3)(ii), and the MOV diagnostic test programs developed in response to NRC GL 89-10, "Safety-Related Motor-Operated Valve Testing and Surveillance" (ADAMS Accession No. ML031150300) and GL 96-05, "Periodic

Verification of Design-Basis Capability of Safety-Related Motor-Operated Valves" ADAMS Accession No. ML031110010), together will satisfy the regulatory requirements of 10 CFR 50.55a(b)(3)(ii).

In GL 89-10, the NRC staff requested that each nuclear power plant licensee establish a program to demonstrate that safety-related MOVs are capable of performing their design basis functions. During the implementation of GL 89-10, the NRC staff provided four acceptable methods a licensee could use to demonstrate the design basis capability of safety-related MOVs. The four methods for demonstrating capability in descending order of acceptability are:

1) Dynamic testing at or near design basis conditions with diagnostics of each MOV where practicable. Valves dynamically tested at less than design basis conditions may be extrapolated with proper justification.

2) Electric Power Research Institute (EPRI) MOV Performance Prediction Methodology (PPM). This method was developed for those valves that could not be dynamically tested. The PPM required internal valve measurements to provide assurance that the valve performance was predictable. The NRC staff began accepting the use of the PPM even where dynamic testing for an MOV was practicable.

3) MOV valve grouping. Where valve-specific dynamic testing was not performed and the PPM was not used, the staff accepted grouping of MOVs that were dynamic tested at the plant to apply the plant-specific test information to an MOV in the group.

4) The use of valve test data from other plants or research programs. The NRC ranks this as the least-preferred approach (with the most margin required) because the licensee would have minimal information regarding the tested valve and its history.

In superseding GL 89-10, GL 96-05 requested that each licensee establish a program, or ensure the effectiveness of its current program, to verify on a periodic basis that safety-related MOVs continue to be capable of performing their safety functions within the current licensing basis of the facility. The program should ensure that changes in required performance resulting from degradation (such as those caused by age) can be properly identified and addressed.

In response to GL 96-05, the nuclear industry joined together to form the JOG MOV periodic verification program. The JOG program consisted of three elements: (1) an "interim" MOV periodic verification program for licensees to use in response to GL 96-05 during development of a long-term program; (2) a 5-year MOV dynamic diagnostic test program; and (3) a long-term MOV periodic diagnostic test program to be based on the information from the dynamic testing program. The JOG effort was intended to answer the valve degradation question as it pertained to valve configuration, design, and system application. The JOG test program was not intended to provide data to the industry for the purpose of justifying valve performance. The final JOG program plan consisted of periodic diagnostic test program that is based on risk and margin.

The NRC staff approved the JOG final program plan, with conditions, in an SE dated September 25, 2006 (ADAMS Accession No. ML061280315).

The ASME OM Code establishes the requirements for preservice and inservice testing and examination of certain components to assess their operational readiness in light-water reactor nuclear power plants. These requirements apply to pumps and valves that are required to perform a specific function in shutting down a reactor to the safe shutdown condition, in maintaining the safe shutdown condition, or in mitigating the consequences of an accident. The

ASME OM Code also applies to pressure relief devices and dynamic restraints.

Prior to the development of Mandatory Appendix Ill, the ASME OM Code testing for MOVs consisted of:

1) Valve exercising to include quarterly stroke time testing

2) Valve obturator movement verification during the exercise test

3) Valve leakage testing (only if the valve has a leakage limit requirement)

4) Remote position indication verification In the past, these required tests were considered to be adequate to assess MOV operational readiness. However over the course of several years of operating experience and testing, it was determined that quarterly stroke time testing of MOVs was not an adequate indicator of valve degradation. As an alternative to MOV stroke-time testing, ASME developed Code Case OMN-1 to allow periodic exercising and diagnostic testing in assessing operational readiness of active MOVs in lieu of quarterly stroke-time testing. ASME provided additional guidance by developing Code Case OMN-11, "Risk-Informed Testing for Motor-Operated Valves," for MOVs in the 1ST program that are determined to have a high safety significance. The NRC staff has reviewed and accepted these Code Cases with certain conditions as noted in Regulatory Guide (RG) 1.192, "Operation and Maintenance Code Case Acceptability ASME OM Code" (ADAMS Accession No. ML19128A261), which is incorporated by reference in 10 CFR 50.55a. ASME merged these two Code Cases into an updated version of Code Case OMN-1 published in the 2006 Addenda of the ASME OM Code. This updated OMN-1 Code Case was later adopted into the 2009 Edition of ASME OM Code as Mandatory Appendix Ill. The NRC conditions for use of Mandatory Appendix Ill are specified in 10 CFR 50.55a(b)(3)(ii).

Most licensees of operating nuclear power plants committed to follow the JOG MOV periodic verification program as part of their response to GL 96-05. The NRC staff reviewed each licensee's GL 96-05 program and risk methodology (including implementation of the JOG program) and prepared an SE describing its review of each of those programs with conditions. Many licensees committed to the Boiling Water Reactor Owners Group (BWROG) risk methodology NEDC-32264A (Revision 2) approved by NRC staff on February 27, 1996, Westinghouse Owners Group (WOG) risk method V-EC-1658-A (Revision 2) approved by NRC staff on August 13, 1998, or a plant-specific risk methodology. The nuclear power plants listed in Table 1 of this SE committed to the following risk ranking method:

1) Limerick - committed to follow the BWROG risk method - SE dated November 17, 2000 (ADAMS Accession No. ML003755447)

2) Braidwood - committed to follow the WOG risk method - Response to Request for Additional Information (RAI) dated April 12, 1999 (ADAMS Accession No. ML17191B310)

3) Calvert Cliffs - committed to follow the WOG risk method - SE dated December 15, 1999 (ADAMS Accession No. ML993550374)

4) Clinton - committed to follow a plant-specific risk method - SE dated February 8, 2000 (ADAMS Accession No. ML003681570)

5) Ginna - committed to follow the WOG risk method - SE dated December 27, 1999 (ADAMS Accession No. ML003672670)

6) Nine Mile - committed to follow a plant-specific risk method - SE dated July 18, 2000 (ADAMS Accession No. ML003729304)

7) Peach Bottom - committed to follow the BWROG risk method - SE dated November 16, 2000 (ADAMS Accession No. ML003752691)

Licensees of operating nuclear power plants must meet the requirements of 10 CFR 50.55a(b)(3)(ii) to follow the ASME OM Code requirements, and have an MOV program that periodically verifies that MOVs will continue to perform their safety functions. The NRC staff considers the JOG program plan and Mandatory Appendix Ill to meet 10 CFR 50.55a(b)(3)(ii) with conditions. Both programs are similar but have differences such as:

1) The JOG program incorporates risk into its MOV diagnostic testing schedule, but Mandatory Appendix Ill does not require the implementation of a risk-informed program. Applying risk in Mandatory Appendix Ill relaxes valve grouping requirements which allows for more flexible testing.

2) The JOG program has specific test intervals based on risk and margin. High risk MOVs have shorter test intervals dependent on margin with a maximum test interval of 6 years for high margin MOVs and 2 years for low margin MOVs. Mandatory Appendix Ill relies on the plant MOV engineer to set the correct test interval not to exceed 10 years based on specific MOV diagnostic test data. High risk valves can be justified to extend the test interval to 10 years.

3) The licensee's implementation of the JOG program is a commitment, whereas the implementation of Mandatory Appendix Ill is a regulatory requirement.

4) The JOG program applies to valve performance, and the licensee is responsible for justifying the periodic verification of the actuator performance.

ASME developed Code Case OMN-26 to reduce the amount of programmatic changes for licensees incorporating Mandatory Appendix Ill for the first time when the licensees update their 1ST program plans. Code Case OMN-26 aligns those portions of Mandatory Appendix Ill to follow the JOG approach of the test interval being based on both margin and risk that has been successfully implemented for the last 20 years. In some instances, Code Case OMN-26 is more restrictive in that certain valves (without periodic design-basis testing) are not allowed to have test intervals up to the 10-year interval allowed in Mandatory Appendix 111. On the other hand, Code Case OMN-26 will allow certain valves to have test intervals based on their risk and margin that are beyond the 10-year interval in Appendix Ill. The NRC staff considers the extensions of the test intervals in Code Case OMN-26 to be reasonable based on many years of successful test data in implementing the JOG program by nuclear power plant licensees.

Another improvement in Code Case OMN-26 is that for high-risk valves with very high margins that are successfully stroked at least once per operating cycle under full design pressure and flow, the test interval may be extended to 12 years. Similarly, the diagnostic test interval for low-risk valves with very high margins and that are successfully stroked at least once per operating cycle under full design pressure and flow, the test interval may be extended to 16 years. Essentially, each successful stroke under full design pressure and flow is a reasonable demonstration of a very high margin MOV being operationally ready to perform its safety function without diagnostic test equipment.

In its letter dated July 6, 2020, the licensee states that the provisions of Code Case OMN-26 will be implemented in their entirety, including all tables and associated notes. The licensee specifies minor clarifications of the notes in the tables in Code Case OMN-26 to be consistent with its normal plant operations. The NRC staff has determined that the licensee's proposed alternative to implement Code Case OMN-26, as described in the licensee's letters dated January 31, 2020, and July 6, 2020, at the nuclear power plants listed in Table 1 of this SE, provides an acceptable level of quality and safety for their current 10-year 1ST program intervals.

4.0 CONCLUSION

As described above, the NRC staff concludes that the proposed alternative to implement ASME OM Code Case OMN-26, as described in the licensee's letters dated January 31, 2020, and July 6, 2020, provides an acceptable level of quality and safety for the nuclear power plants listed in Table 1 of this SE. Accordingly, the NRC staff concludes that the licensee has adequately addressed all of the regulatory requirements set forth in 10 CFR 50.55a(z)(1 ).

Therefore, the NRC staff authorizes the proposed alternative for the implementation of ASME OM Code Case OMN-26, for the specified 10-year 1ST program intervals for the nuclear power plants listed in Table 1 of this SE.

All other ASME OM Code requirements for which relief or an alternative was not specifically requested and approved in the subject requests remain applicable.

Component Number System Code Class Category 1/2MS001A Main Steam 2 B 1/2MS001B Main Steam 2 B 1/2MS001C Main Steam 2 B 1/2MS001D Main Steam 2 B Component Function(s)

These are the Main Steam Isolation Valves (MSIVs). In the normally open position, steam is supplied to the turbine. The valves are required to close to isolate the main steam line to prevent: reverse flow into containment during a main steam line break, Steam Generator Blowdown during a major steam line break outside of containment, and secondary system contamination from a Steam Generator tube rupture.

Justification Closure of the main steam isolation valves IMS00IA-D or 2MS001A-D during Unit operation would result in a significant steam generator transient and a manual reactor trip. Failure of these valves during partial stroke testing can result in valve closure and subsequent reactor trip.

Because stroke testing of these valves at power would result in a reactor trip, and because patiial stroke testing at power presents the unwarranted risk of a potential reactor trip, testing of these valves during operation is not practical. Stroke time testing of the Main Steam Isolation Valves will be completed during cold shutdown, as conditions allow, in accordance with ISTC-3521(c).

The actual test modes are Modes 3-6, but normally testing is performed in Modes 3 or 4 before or after cold shutdowns.

These are the main feedwater isolation valves (FWIVs). They are open during normal operation to allow flow to the Steam Generator (non-IST function). They are required to close for Feedwater Isolation and Containment Isolation. (Not subject to Type C leakage testing per Tech Spec Table B.3.6.3-1.)

Justification The main feedwater isolation valves cannot be fully stroked during operation as feedwater would be terminated causing a reactor trip. Failure of these valves during partial stroke testing can result in valve closure and subsequent reactor trip.

Because stroke testing of these valves at power would result in a reactor trip, and because partial stroke testing at power presents the unwarranted risk of a potential reactor trip, testing of these valves during operation is not practical.

The l/2CV8152 and the 1/2CV8160 are the letdown line containment isolation valves. These valves are part of the chemical and volume control system (CVCS).

Justification Closure of these letdown isolation valves I /2CV8152, and 1/2CV8160 during normal Unit operation would cause a loss of charging flow which would result in a reactor coolant inventory transient, and possibly, a subsequent reactor trip. Additionally, isolating letdown during normal Unit operation would result in a thermal transient on the charging nozzle. Valves 1/2CV8152 and l/2CV8160 will be stroke time tested during cold shutdown in accordance with ISTC-352l(c) (also covers fail-safe tests for I /2CV8 I 52 and l /2CV8 l 60). It is not the intent of this justification to require charging pump shutdown only to perform the exercise test for these valves. Valves 1/2CV8 I 52 and l/2CV8 I 60 will be tested during Cold Shutdown in which the charging pumps are secured for sufficient duration to perform the tests, which is in accordance with ISTC-3521 (c ).

These are the reactor head vent valves and are used to vent the reactor of hydrogen or other post-accident gases.

Justification The Reactor Pressure Vessel Vent Valves 1RC014A-D and 2RC014A-D cannot be stroked during Unit operation, as they provide a pressure boundary between the Reactor Coolant system and containment atmosphere. Failure of one of these valves in the open position would result in leaving only one valve as the high pressure boundary. These valves will be full stroke exercised and fail safe tested when the RCS pressure is at a minimum during cold shutdown, in accordance with ISTC-3521 (c).

Component Number System Code Class Category 1/2RH8730A Residual Heat Removal 2 C 1/2RH8730B Residual Heat Removal 2 C Component Function(s)

These are the RHR pump discharge check valves. The open function of these valves is to provide an RHR pump flowpath. The closure function is to prevent back leakage while the opposite train is in operation during post-accident situations.

Justification The Residual Heat Removal Pump discharge check valves 1RH8730A/B and 2RH8730A/B cannot be full stroke exercised during Unit operation due to the RCS pressure being greater than the RHR pumps are capable of delivering. Since the RH pumps cannot be run on full flow conditions during normal operation, the ability to pass design accident flow through the subject check valves is not possible. Although not required, these check valves will be partial stroke tested, however, on a quarterly basis during the mini-flow recirculation RHR pump tests and full stroke exercised during cold shutdown. This is in accordance with ISTC-3522 (b).

Additionally, it would be impractical to backflow test these valves during Unit operation. The methodology for testing these valves involves closing the mini-flow valve on the train being tested and subsequently cross-tying the RH pumps discharge headers and having the opposite train provide pressure against the check valve being tested. The test is satisfied by verifying that the pump on the same train as the check valve is not rotating backwards. However, this testing would put the plant in an undesirable condition as both trains of RH would be considered inoperable.

During cold shutdowns, the train running on shutdown cooling may be used to pressurize against the opposite train's check valve. For this reason, these valves will be backflow tested during cold shutdown in accordance with ISTC-3522(b).

The SI8818 valves are the safety injection RCS Loop I cold leg upstream check valves located in the flowpath from the Residual Heat Removal (RHR) pumps. The Sl8958 valves are the safety injection RWST outlet check valves to the RHR pumps.

Justification Due to the high RCS pressure during Unit operation (2235 psi), these valves cannot be full or partial stroke exercised during quarterly testing. The 1/2SI8958A/B check valves, although located at the suction of the RHR pumps, are not in the recirculation flow path to allow partial stroking each quarter.

These valves will be full stroke exercised during cold shutdown, in accordance with ISTC-3522(b).

Component Number System Code Class Category 2FW039A Feed Water 2 B 2FW039B Feed Water 2 B 2FW039C Feed Water 2 B 2FW039D Feed Water 2 B Component Function(s)

These are the steam generator feedwater preheater bypass downstream isolation valves. They provide for Feedwater/Containment isolation in the closed position. (Not subject to Type C leakage testing per Tech Spec Table B.3.6.3-1.) They are normally open air operated valves located on the cross-tie lines connecting the main FW line to the tempering line.

Justification It is not practical for the 2FW039A-D valves to be stroke tested during normal operation as closure of these valves would require a power reduction from full power to less than 80%. Stroking these valves closed above 80% would result in undesirable Steam Generator preheater tube vibrations thereby causing undue stress and potentially reducing the life expectancy of the Steam Generators ..

These valves will be stroke timed and fail safe tested during cold shutdown, in accordance with ISTC-3521 (c).

COLD SHUTDOWN JUSTIFICATION: CS-10 (Page 1 of 1)

Component Number System Code Class Category 1/2CV459 Chemical And Volume Control 1 B 1/2CV460 Chemical And Volume Control 1 B Component Function(s) 1/2CV459 and 1/2CV460 valves are normally OPEN with the Unit at power, allowing letdown flow to occur. The valves auto close on low Pressurizer level and on letdown isolation due to an interlock with the orifice isolation valves.

Justification It is impractical to full or partial stroke exercise and stroke time the above listed valves on a quarterly basis. Due to the interlocks between the 1/2CV459, 1/2CV460, & the 1/2CV8149A-C valves, exercising these valves during normal operation results in (multiple) total letdown flow isolation events. The impact of a letdown isolation with the Unit at power is a thermal transient to the RPV charging nozzle. A letdown isolation also results in some amount of pressurizer level fluctuation until equilibrium letdown and makeup is re-established. While the piping and components are designed for thermal transients, each cycle presents some additional stress to all of the affected equipment. As implied in section 2.4.5 of NUREG-1482, Revision 2, it is prudent to minimize the number of transients the equipment is required to undergo to prevent premature failures.

Due to the above, these valves will be stroke tested and failed safe tested in Cold Shutdowns in accordance with ISTC-3521 (c ).

Component Function(s)

The listed valves have been identified as intersystem LOCA valves. Only the closed function of these valves will be addressed in this justification. These valves form a pressure boundary between the RCS and the other essential components in order to protect these components from damage.

Justification All of these valves are considered pressure isolation valves (PIVs) per the Technical Specifications, except for the l/2RH8705A/B valves, which will be tested on the same frequency since they are tested in conjunction with the 1/2RH8701A/B valves. Online closure verification constitutes a leak test, which presents significant hardships such as the use of temporary test equipment inside containment, excessive radiation exposure to test personnel, and entry into multiple and simultaneous LCO's thereby making closure testing impracticable. The performance of the leak test also satisfies the test required for ASME OM Code, ISTC-3630. These valves will be backflow/leak tested during cold shutdowns, in accordance with ISTC-3521(c) and ISTC-3522(b).

Additionally, pressure isolation valves are required to be tested in accordance with Technical Specification SR 3.4.14.1. The Technical Specification requires that if the Unit is in cold shutdown for 7 days or more and the valves have not been tested in the past nine months, they will be leak tested prior to entry into Mode 2.

1/2SI8948A-D; 1/2SI8956A-D Note Valves l/2SI8948A-D and 1/2SI8956A-D are now in the Condition Monitoring Program. Should they be removed from that program they would require being tested to the "regular," valve Code -

ISTC, in accordance with this deferral. These valves are surveillance tested with the above valves, at a Cold Shutdown frequency, as they are required to be by the Technical Specifications. They will continue to be listed in this Cold Shutdown Justification for these reasons.

Component Number System Code Class Category 2RH8716A Residual Heat Removal 2 B 2RH8716B Residual Heat Removal 2 B Component Function(s)

Valves 2RH8716A/B are the Residual Heat Removal system cross connect valves that are required to be open to allow injection into the RCS loops. These valves are required to be open for train operability of either train of RHR. The valves are required to be closed during cold leg recirculation and open during hot leg recirculation.

Justification Technical Specifications require these valves to be open. Stroking this valve closed would make both trains of RH inoperable, which is a violation of the Technical Specification. This valve can only be exercised during cold shutdown or refuel. These high risk ranked valves will be exercise tested and, if applicable, stroke time tested during Cold Shutdown conditions.

COLD SHUTDOWN JUSTIFICATION: CS-15 (Page 1 of I)

Component Number System Code Class Category 1/2CC685 Component Cooling 2 A Component Function(s)

Motor operated valves I /2CC685 function in the closed position to provide a limited leakage barrier between the containment atmosphere and the environment during accident conditions. These valves open to provide a return flow path from the RCP Thermal Barrier.

Justification These valves cannot be full or pa11ial stroke exercised during normal operations because closure would isolate flow to the Reactor Coolant Pumps. Failure of a CC valve in the closed position during an exercise test would result in a loss of cooling flow to the pumps and eventual pump damage and/or trip. Therefore, these high risk ranked valves will be stroke tested during cold shutdowns, in accordance with III-3620 provided all of the RCPs are shutdown. This test frequency will adequately maintain these valves in a state of operational readiness by testing them as often as safely possible.

This frequency is consistent with the guidelines presented in NUREG-1482, Revision 2, Section 3.1.1.4.

Note: Valves 1/2CC9413A, 1/2CC9413B, 1/2CC9414, l/2CC9415, 1/2CC9416, 1/2CC9438, 1/2CV8100, and 1/2CV8112 have been removed from this CS deferral based on implementation of ASME OM Code Appendix Ill. These MOVs have a risk ranking of Low and are therefore only required to be exercise and/or stroke time tested once every 18 months.

The SD054 valves are normal Steam Generator Slowdown throttle control valves. An additional function of the Unit 1, (A through H valves) and the Unit 2, (B train valves [B, D, F, & H]) is to isolate Slowdown in the event of a High Energy Line Break (HELS) in the SD system.

Justification It is impractical to exercise and stroke time the above listed valves on a quarterly basis. The valves have no Open/ Closed hand switch. They are normally operated by means of a potentiometer which ultimately controls an air signal to a positioner. Attainment of repeatable stroke time results requires the valves to be stroked by causing ( or simulating) HELS relay actuation. This method of closure causes multiple valve actuations resulting in complete steam generator blowdown isolation. Furthermore, the remote position indicator, (a 0-100%

indicator - not based on limit switch operation) may lag actual valve position. Therefore, the only repeatable method of stroke timing these valves involves stationing personnel locally at the valve(s) to witness actual valve movement.

Full stroke exercising the valves is a Unit operation concern in that closure of these valves during normal operation presents a thermal transient to the downstream piping and components including the blowdown condenser. While the valves, piping, and components are designed to withstand this thermal transient, each transient produce's stress which may lead to premature failure of the affected components. As implied in section 2.4.5 of NUREG-1482, Revision 2, it is prudent to minimize the number of thermal transients that these high energy lines are required to undergo.

COLD SHUTDOWN JUSTIFICATION: CS-18 (Contd.)

(Page 2 of 2)

Personnel safety concerns exist with this stroking exercise during normal operation in that the valves are physically located in the Main Steam Isolation (MSIV) Valve Room, off the Steam Tunnel. This room contains the MSIVs, Peedwater Isolation Valves (PWIVs), Main Steam Safety Valves, Main Steam PORVs, and other miscellaneous piping and valves. The normal ambient temperature in this room with the Unit at power is greater than 110 °P. Almost all of the piping (most of which is insulated) and instrument tubing in the room are normally at temperatures of approximately 500 °P or more. The SD054 valves are located above the floor some 16 to 20 feet and are not visible from the floor being obscured by Main Steam and Peedwater Piping. Since personnel must be stationed locally at the valve to witness actual valve movement, it is necessary to climb around very hot piping in a hot and very noisy ambient atmosphere. In some cases it may be necessary to erect scaffolding to conduct this test with the Unit in normal operation.

Due to the above, these valves will be stroke time/fail safe tested during Cold Shutdowns of sufficient duration to allow safe access to the valves, including the erection of scaffolding, if required. This testing frequency is in accordance with ISTC-3521 (c).

FUNCTION(S):

The normally open butterfly SX Outlet Throttle Valves for the respective unit's CC Heat Exchanger, which provides a flow path for SX through the associated CC Heat Exchanger.

JUSTIFICATION:

Full and Partial exercising the 1/2SX007 valves presents a concern for the equipment cooled by the CCW System. The l /2SX007 flow control valves are normally throttled to provide proper flow to the applicable unit's CC heat exchanger. The Unit O CC heat exchanger is aligned to one unit at a time. Full stroke of the 1/2SX007 for the unit not aligned to the Unit O CC heat exchanger results in a loss of cooling to CC components on the applicable cooling loop. As a result, performance of the 1/2SX007 valve strokes requires swapping the Unit O CC heat exchanger to the applicable unit.

Swapping the Unit O CC heat exchanger between Unit 1 and Unit 2 is a concern for equipment cooled by the CCW System.

TEST FREQUENCY:

The 1/2SX007 high risk ranked valves will be exercised during refueling outages in accordance with III-3620.

FUNCTION(S}:

The normally closed gate Containment recirculation sump isolation motor operated valves (MOY) provide an isolation boundary between the suctions of the residual heat removal (RH) and containment spray (CS) pumps, and the containment recirculation sumps. They are considered high safety significant components (HSSC) under ASME OM Code Appendix III.

ASME OM Code 2012 Edition, III-3610 "Normal Exercising Requirements states that all MOYs, within the scope of this Mandatory Appendix, shall be full cycle exercised at least once per refueling cycle with the maximum time between exercises to be not greater than 24 mo. Full cycle operation of an MOY, as a result of normal plant operations or Code requirements, may be considered an exercise of the MOY, if documented. If full stroke exercising ofan MOY is not practical during plant operation or cold shutdown, full stroke exercising shall be performed during the plant's refueling outage.

Sub-section III-3721 states that "HSSC MOYs shall be tested in accordance with para. III-3300 and exercised in accordance with para. III-3600. HSSC MOYs 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." This establishes the requirement that these particular MOYs should be tested quai1erly unless there is adequate justification that they cannot be operated during plant operation and suppo11ing documentation is available showing that the potential increase in core damage frequency (CDF) and large early release (LER) associated with a longer exercise interval is small.

JUSTIFICATION:

Under normal plant operating conditions, the RH and CS systems are filled with borated water and the containment recirculation sumps are maintained in a dry state. A stroke test of these valves requires the RH and CS pumps for a given train to be removed from service and the Revision Date: November 25, 2020 IST-BRW-PLAN

REFUEL OUTAGE JUSTIFICATION RJ-2 (Continued) suction lines drained to prevent water flow from the refueling water storage tank (RWST) and associated system piping into the normally empty containment recirculation sump.

An estimated 600 gallons of radioactive, borated water are drained and must be processed by the radioactive waste systems.

This same amount of borated water must be used to refill the system. This sequence of events is required whether the testing is done online or during a refueling outage. In addition, this testing process would render a train of RH and CS simultaneously inoperable for a period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> each quarter. Based upon the complexity of the actions that are required to stroke test the valves, as well as the impact upon plant configuration and risk associated with the concurrent inoperability of an RH and CS train, it is not practical to perform these activities on a quaiierly frequency during operation or during cold shutdowns.

TEST FREQUENCY:

Valves l/2SI881 IA and l/2SI8811B will be exercise tested as required by ASME OM-2012 Code, Appendix III during every refuel outage.

REFUEL OUTAGE JUSTIFICATION RJ-3 CODE DRAWING DRAWING VALVE NUMBER CATEGORY CLASS NUMBER COORDINATE l/2IA065 A 2 M-55-4(M-55-5) D3 (E6) 1/2IA066 A 2 M-55-4(M-55-5) D6 (E4)

FUNCTION(S):

Air Operated Valves 1/2IA065 and 1/2IA066 are the outboard and inboard (respectively) containment isolation valves for Instrument Air supply lines to containment. The closed safety function of these valves is to provide a leak-tight barrier between the containment atmosphere and the environment during accident conditions.

JUSTIFICATION:

Stroke/fail-safe testing of the 1/2IA065 and l/2IA066 valves during plant operation or cold shutdowns would, by design, isolate the air to air operated instruments inside the containment building. Additionally, the valve's control circuitry does not provide for partial stroke capability.

Stroke/fail-safe testing would introduce the possibility of major operating perturbations and/or personnel safety concerns should these valves fail to re-open during testing activities. This would result in scenarios such as:

1. Loss of Pressurizer Pressure Control -

The pressurizer spray valves 1/2RY455B & C and the pressurizer auxiliary spray valve 1/2CV8145 would fail closed and not be available for pressurizer pressure control.

2. Loss of Chemical Volume Control System Letdown Flow (both normal and excess) and Charging Flow -

The loss of instrument air would cause a disruption in the Unit letdown flow paths resulting in pressurizer level increases. Such valves as the letdown orifice containment outlet header isolation valve l/2CV8160, the letdown line isolation valves 1/2CV459 and 1/2CV460, the letdown orifice outlet isolation valves 1/2CV8149A, B & C, the excess letdown heat exchanger inlet isolation valves 1/2CV8153A & B, and the regenerative heat exchanger letdown inlet isolation valves 1/2CV8389A & B would go to their fail closed positions.

Additionally, the ability to normally make-up reactor coolant inventory and adjust the reactor chemical shim (i.e. normal boration/dilution) would also be lost as the regenerative heat exchanger inlet isolation valves 1/2CV8324A & B would fail to their respective closed positions.

REFUEL OUTAGE JUSTIFICATION RJ-3 (continued)

3. Loss of Component Cooling to Containment Penetrations -

The loss of instrument air supply would cause the penetration cooling supply flow control valve 1/2CC053 to go to its fail closed position. The loss of penetration cooling would result in elevated temperatures being imposed on the penetrations being supported by the component cooling system.

4. Loss of Personnel Breathing Air -

The loss oflnstrument Air supply to the Service Air downstream isolation valve l/2SA033 would cause this valve to go to its fail close position. This loss of Service Air in the containment building would eliminate the normal source of supplied breathing air needed to support numerous maintenance and component inspection activities in a contaminated environment.

TEST FREQUENCY:

Air Operated Valves 1/2IA065 and 1/2IA066 will be stroke tested and fail safe tested during refueling outages on the respective Unit in accordance with ISTC-3521(e).

REFUEL OUTAGE JUSTIFICATION RJ-4 (continued)

JUSTIFICATION:

These valves cannot be full stroke exercised during operation as the shut-off head of the Safety Injection pumps is lower than the reactor coolant system pressure. These valves cannot be full stroke exercised during routine Mode 5 cold shutdowns due to the Braidwood Station Technical Specification requirement that all Safety Injection pumps and all but one Charging pump be inoperable during Modes 4, (temperature less than 330 F) 5, and 6, except when the reactor vessel head is removed. This requirement minimizes the possibility of low temperature over pressurization (L TOP) of the Reactor Coolant System (RCS). The alternate method of protecting against over-pressurization by partially draining the RCS to provide a surge volume is not considered a safe practice due to concerns of maintaining adequate water level above the reactor core. Full stroke exercising of these valves may only be safely performed in Mode 6 with the Reactor vessel head removed.

This refueling outage justification will only include the open functions of all the check valves listed above.

Check valves 1/2SI8815 are located in the lines from the Chemical and Volume Control (CV)

Centrifugal Charging pump. Their safety function in the open direction is to permit flow of coolant from the centrifugal charging pumps to the four lines which branch off and provide flow to the reactor vessel cold legs during the high pressure injection phase of a safety injection.

Check Valves l/2SI8900A-O are in the four lines which branch off from the lines containing the 1/2SI88 l 5 valves. Their safety function in the open direction is to permit flow of coolant from the chemical and volume Control Centrifugal Charging Pumps to the reactor vessel cold legs during the high pressure injection phase of a safety injection.

Check valves l/2CV848 l A/Bare located at the discharge of the Chemical and volume Control charging pumps. They are required to open to permit flow of coolant during a safety injection.

JUSTIFICATION:

The full stroke exercising of check valves 1/2SI8815 and l/2SI8900A-O associated with the Emergency Core Cooling System during operation would induce thermal stresses on their respective reactor vessel nozzles as the Reactor Coolant System (maintained at greater than 500° F) is injected with water from the Refueling Water Storage Tank (maintained at approximately 65° F).

The 1/2CV848 l A/B check valves are in series and cannot be full stroke exercised without causing stroking of 1/2SI8815 and l/2SI8900A-O check valves.

Revision Date: November 25, 2020 IST-BRW-PLAN

REFUEL OUTAGE JUSTIFICATION RJ-5 (continued)

These valves cannot be full stroke exercised during routine Mode 5 cold shutdowns due to Braidwood Station Technical Specifications LCO 3 .4.12 requirements that all Safety Injection pumps and all but one charging pump be inoperable during Modes 4, (temperature less than 330 F) 5, and 6, except when the reactor vessel head is removed. This requirement minimizes the possibility of low temperature over pressurization (LTOP) of the Reactor coolant System (RCS).

The alternate method of protecting against over-pressurization by partially draining the RCS to provide a surge volume is not considered a safe practice due to concerns of maintaining adequate water level above the reactor core. In addition, injecting large quantities of highly borated water from the R WST would likely delay reactor start up and the cost of processing the reactor coolant to restore the optimum boron concentration is consequential. Full stroke exercising of these valves may only be safely performed in Mode 6 with the Reactor vessel head removed.

All of the "A/C" category valves in this refueling outage justification are pressure isolation valves (PIVs) and will be leak tested (and backflow tested) per Braidwood Station Tech Specs (see CS-13). This refueling outage justification will only include the open functions of all the check valves listed above.

Check valves l/2SI884 l A/B are located in the lines from the Residual Heat Removal (RHR) pumps to the "A" and "C" Reactor Coolant System hot legs. Their safety function in the open direction is to permit flow of coolant from the RHR pumps to the reactor vessel hot legs during the Hot Leg Recirculation phase of a safety injection.

Check Valves l/2Sl8949A/C are located in an ECCS line to the RCS "A" and "C" hot legs. They are required to open to permit flow of makeup water upon a safety injection from: (1) the Safety Injection Pumps during the high pressure safety injection phase, or (2) the RHR pumps during the Hot Leg Recirculation phase, to the reactor vessel hot legs.

JUSTIFICATION:

The full stroke exercising of check valves I/2SI8841 A/B and 1/2SI8949A/C, associated with the Emergency Core Cooling System (ECCS) and the Residual Heat Removal (RHR) System cannot be accomplished during normal reactor operation because the low head developed by the RHR pumps (less than 250 psi) is not great enough to inject into the RCS (2235 psi). Similarly, the 1/2SI8949A/C check valves cannot be partial stroke tested during normal reactor operation with the Safety Injection (SI) pumps since the RCS pressure cannot be overcome by the SI pump developed head (1500 psi).

Full or partial stroke testing of these valves during cold shutdowns would induce thermal stresses on their respective reactor vessel nozzles as the Reactor Coolant System (maintained at approximately 180° F) is injected with water from the Refueling Water Storage Tank (maintained at approximately 65° F). Additionally, the margin of safety is reduced for brittle fracture prevention and an unacceptable reactivity excursion could be created (high boron concentration and low temperature water).

REFUEL OUTAGE JUSTIFICATION RJ-6 (continued)

Finally, during cold shutdowns in which the Technical Specification leak rate testing is not to be performed, the partial or full stroking of these valves would necessitate the requirement to perform the leak test on these check valves, causing a delay in returning the plant to power in addition to causing unnecessary radiation exposure to test personnel.

These check valves are leak tested in conjunction with pressure isolation valves (PIVs) 1/2RH8701 B and 1/2RH8702B and will be leak tested (and backflow tested) at the same frequency as the 1/2RH8702B valves (see CS-13). This refueling outage justification will only include the open functions of the check valves listed above.

These valves are located on the 3/4" branch line between the 1/2RH8701A/B and 1/2RH8702A/B suction isolation valves. Their safety function in the open direction is to relieve excess pressure due to thermal expansion back to the RCS when both suction isolation valves are closed in order to prevent over pressurization of the piping between the two valves.

JUSTIFICATION:

These valves are simple spring-loaded lift check valves and are not equipped with an external operator or disk position indicator. The only way to verify operability in the open direction is by verifying that the piping between the suction isolation valves is able to be depressurized through the applicable valve via a field test. It would be impractical to perform this testing during Unit operation due to the necessity to enter containment, hookup a pressurized water source to the piping via a test/vent valve, and slowly increase the pressure until the check valve opens to relieve the pressure. Additionally, the RCS must be depressurized in order to perform this test.

It would be impractical to perform this test during cold shutdowns as it requires placing the standby train of Residual Heat Removal (RHR) in an inoperable condition and the RCS must be depressurized (requires all reactor coolant pumps to be stopped). Then, due to the extensive field work involved, there is a potential for delaying reactor stai1 up and return to power. Additionally, taking away the backup/redundant train of RHR reduces both the plant decay removal capability and the available safety margin regarding shutdown risk assessment.

Testing these valves each refueling, in Mode 6, is adequate to maintain this pot1ion of RHR in a state of operational readiness, while not sacrificing the safety of the plant.

FUNCTION(S):

The Feedwater Regulating Bypass Valves (1FW510A. 1FW520A, 1FW530A, and 1FW540A), the Feedwater Regulating Valves (I FW5 I 0, 1FW520, I FW530, and 1FW540) and the Feedwater Tempering Flow Control Valves (1 FW034A-D) are non-safety related valves which perform a backup function to isolate Feedwater. These valves are not considered to be Containment Isolation Valves per the Braidwood Station Technical Specifications, and are considered only Feedwater Control Valves that, additionally, serve as backup Feedwater Isolation Valves. They are not considered to be in the scope of the 1ST Program (per ISTA- 1100). This has always been Braidwood's position on these valves. However, since they do receive a Feedwater Isolation signal, an augmented test to verify the fail-safe test will be tracked within the IST Program.

JUSTIFICATION:

The augmented Fail-Safe test will be performed. These valves are all part of the surveillance executed to satisfy Technical Specifications, which manually simulates an SI signal, causing these valves to fail closed. These valves will be fail-safe tested to satisfy the requirements of this Technical Specification (Refueling Outage Frequency).

Additionally, the closure of the Main Feedwater Regulating Bypass Valves (l/2FW510A, l/2FW520A, l/2FW530A, and l/2FW540A) during Unit operation would require the Main Feed water Regulating Valves to correct for bypassed flow and could result in a plant transient with Revision Date: November 25, 2020 IST-BRW-PLAN

Finally, it would be impractical to fail-safe test any of these augmented valves on a more frequent basis than required by the Technical Specifications.

FUNCTION(S):

These valves are the instrument air supply check valves to the RF pump discharge containment isolation valves. These valves must close to isolate the I /2RF026 valve actuator air supply from the non-safety related instrument air system. This function assures that sufficient air is available in the accumulator to close the containment isolation valve on demand. This valve prevents discharging the accumulator in the event of a failed instrument air supply which is non-safety related.

The valve opens to provide air supply from the instrument air system to the containment isolation valve accumulator. The accumulator provides operating gas to the containment isolation valve.

This is a safety function since the instrument air system is not considered safety related and not relied upon for safe shutdown or accident mitigation.

JUSTIFICATION:

Check valves l/2RF026-I/A-CHK have been investigated for possible closure testing. The open function is verified during the quarterly stroke test of the l/2RF026 valves.

The closure testing performed on these valves requires isolating the air supply and accumulator to perform a back-seat test. Performing this test involves opening an air fitting to bleed the air off locally. This would require a containment entry each quarter which would result in increased dose which is not consistent with ALARA principles. Additionally, should l/2RF026 fail to re-open, there would be an impact inside missile barrier as the RF sump would have no path to pump down which could result in it overflowing. This would result in emergent work inside containment while on line.

The l/2RF026 and l /2RF027 valves serve as containment isolation valves, and are in series on penetration 47, with the l/2RF026 valves inside containment and the l/2RF027 valves in the aux building. Only one of these valves is required to function to maintain containment integrity. The l/2RF027-I/A-CHK check valves will be tested quarterly, as there are no accessibility or dose issues associated with those.

PUMP TECHNICAL POSITION (Contd.)

TP-PA-1 Therefore, for the Braidwood Unit 1 and Unit 2 Group B Auxiliary Feedwater Pumps, a Group A pump test will be performed in lieu of a Group B pump test. For the Unit 1 and Unit 2 Group B Containment Spray Pumps, a Comprehensive pump test will be performed in lieu of a Group B pump test.

Comprehensive Pump Tests - Comprehensive pump tests are performed biennially for all pumps in the Inservice Testing Program. Comprehensive pump test flow rates have been established which effectively detect mechanical and hydraulic degradation during subsequent testing. The best efficiency point, system flow rates, and any other plant-specific flow rates are considered (ISTB-2000). Accident condition flow rates for a single pump will be used as the pump design flow rates.

The following Inservice Test parameters are measured for each Comprehensive pump test:

• Speed (if pump is variable speed)

• Differential Pressure, (for centrifugal pumps)

• Discharge Pressure, (for positive displacement pumps)

• Flow Rate

• Vibration Pump Periodic Verification Tests - Pump Periodic Verification Tests (PPVT's) are performed biennially to verify that certain applicable pumps can meet the required (differential or discharge) pressure as applicable, at its highest design basis accident flow rate. A PPVT is not required if the design basis accident flow rate in the credited safety analysis (e.g., technical specifications, technical requirements program, or updated safety analysis report) is bounded by the Comprehensive Pump Test or Group A Test. The following Inservice test parameters are measured for each Pump Periodic Verification Test:

• Differential Pressure, (for centrifugal pumps)

• Discharge Pressure, (for positive displacement pumps)

PUMP TECHNICAL POSITION TP-PA-2 PUMP NUMBER: 0AB03P, 1AB03P, 2AB03P ASME CODE CLASS: 3 POSITION:

The Boric Acid Transfer Pumps fall outside the scope of the 1ST Pump Program statement of ISTB-1200(b) because they are not provided with an emergency power source (non-ESF buses supply/feed these pumps). Braidwood Station is analyzed as a "hot shutdown" plant, and these pumps are not required to maintain hot shutdown conditions. Also, the R WST (Refueling Water Storage Tank) is a Seismic Category I Structure as described in the UFSAR, Table 3.2-1.

Paragraph 3 .2.1.1 states that Seismic Category I Structures are designed to withstand design basis accidents including tornadoes; therefore, the Boric Acid Transfer Pumps are not required to be included in the 1ST Program to satisfy any Design Basis Accident. Engineering correspondence CHRON # 161733 dated January 17, 1991 suppo1is these conclusions. However, because of the operating significance of these pumps, Braidwood Station has developed a testing program for these pumps outside the IST Program.

PUMP TECHNICAL POSITION TP-PA-3 TITLE:

Instrument Accuracy Requirements for Inservice Pump Testing CODE REQUIREMENTS/DISCUSSION:

This position is only applicable to ASME OM Code Inservice Testing of pumps.

Position

• The accuracy requirements of ASME OM Code 2012 Edition, ISTB-3510 and Table ISTB-3500-1 apply to the accuracy to which installed instruments are calibrated.

• For instrument loops, the accuracy requirements apply to the accuracy to which the instrument loop is calibrated. If the instrument loop is not calibrated as a loop, then a loop accuracy calculation is performed.

• To calculate loop accuracy, either the greater of reference accuracies for individual components or the calibration tolerance for the individual components should be summed using square root of the sum of squares.

Justification This position is based on a review of code interpretations and definitions in recent versions of the Code. Discussions with ASME Subgroup on Pumps members indicate that this position is consistent with industry practice and code intent. The purpose of the accuracy requirements in the code is to ensure that measurements can be used to trend pump performance and identify degradation. Calibration of instruments to the criteria in Table ISTB-3500-1 ofISTB provides the level of quality and assurance to fulfill this purpose.

Interpretation 91-3 states that Table 1 of Part 6 applies only to the calibration of the instrument.

(This was in response to a question on whether the final indication of flow rate on an analog instrument must be within 2% of full scale of actual process flow rate, taking into account attributes such as orifice plate tolerances, tap locations, and process temperatures.)

Question I oflnterpretation 95-07 states that it is the intent of Part 6 "to consider only the instrument's reference accuracy, such as supplied by the instrument manufacturer, in determination of instrument loop accuracy." An instrument loop is defined in the code as "two or more instruments or components working together to provide a single output." It was this interpretation that led to the assumption during the AE inspection that the only permissible way to determine loop accuracy was to combine reference accuracies of the individual loop components using square root of the sum of squares. However, discussions with OM-6 working group members indicate that the intent of this interpretation was to clarify that loop accuracy calculations did not need to consider Revision Date: November 25, 2020 IST-BRW-PLAN

PUMP TECHNICAL POSITION TP-PA-3 (continued) environmental effects, process effects, and vibration effects on loop accuracy (see Question 2 of Interpretation 95-07).

Section 5.5.4 ofNUREG 1482, Revision 2, discusses the accuracy of flow rate instrument loops. It states that the accuracy for analog instruments specified in Subsection ISTB-3500 applies only to the calibration of the instruments.

Starting with the OM-1994 addendum of the code, the definition of instrument accuracy is clarified to read, " ... the allowable inaccuracy of an instrument loop based on the square root of the sum of the square of the inaccuracies of each instrument or component in the loop when considered separately. Alternatively, the allowable inaccuracy of the instrument loop may be based on the output for a known input into the instrument loop." From this definition, it is clear that calibration of an instrument or instrument loop to the OM Code accuracy criteria meets the Code requirements.

PUMP TECHNICAL POSITION TP-PA-4 TITLE:

Categorization of RHR and CS pumps as centrifugal pumps PUMPS AFFECTED:

lRH0lPA, lRH0lPB, 2RH01PB, 2RH01PB, lCSOlPA, lCS0IPB, 2CS01PA, 2CS01PB CODE REQUIREMENTS/DISCUSSION:

Pumps are tested in accordance with ASME OM Code 2012 Edition, Subsection ISTB, "Inservice Testing of Pumps in Light-Water Reactor Power Plants". Within this document, requirements for acceptance criteria and required action ranges are established in accordance with Table ISTB-5221-1, for Ve1iical Line Shaft and Centrifugal Pumps Test Acceptance Criteria. Subsection ISTB-2000 defines vertical line shaft pumps as, a ve1iically suspended pump where the pump driver and pump element are connected by a line shaft within an enclosed column.

The ASME OM Code directs vibration measurements for centrifugal pumps to be taken in a plane approximately perpendicular to the rotating shaft in two 01ihogonal directions on each accessible pump bearing housing. Measurements are also to be taken in the axial direction on each accessible pump thrust bearing housing. For vertical line shaft pumps vibration measurements are required to be taken on the upper motor bearing housing in three 01ihogonal directions, one of which is the axial direction.

Braidwood Station's RH and CS pumps do not meet the definitions of vertical line shaft pumps as provided in Subsection ISTB-2000. While the pumps are in a ve11ical configuration, the entire pump/motor is accessible and vibrations are being taken where needed. These pumps are single-stage centrifugal pumps with no bearings, and the pump impeller is mounted directly to the motor shaft. Braidwood meets the ISTB requirements for centrifugal pumps by recording vibrations on the lower motor bearing in three directions and upper motor bearing in two directions.

POSITION:

Braidwood Station categorized the RH and CS pumps as centrifugal pumps for testing in accordance with ASME OM Code 2012 Edition, Subsection ISTB, Inservice Testing of Pumps in Light-Water Nuclear Reactor Power Plants. This is in accordance with Table ISTB-5121-1, for Centrifugal Pumps Test Acceptance Criteria.

PUMP TECHNICAL POSITION TP-PA-5 TITLE:

Classification of Skid Mounted Components PURPOSE:

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

BACKGROUND:

The ASME Code allows classification of some components as skid mounted when their satisfactory operation is demonstrated by the satisfactory performance of the associated major components.

Testing of the major component is sufficient to satisfy Inservice Testing requirements for skid mounted components. In section 3.4 ofNUREG 1482 Revision 2, the NRC supports the designation of components as skid mounted:

"The staff has determined that the testing of the major component is an acceptable means to verify the operational readiness of the skid-mounted components and component subassemblies if the licensee documents this approach in the 1ST Program Document.

Licensees should consider and document the specific measurements and attributes of major component testing which relate to the assessment of skid-mounted component condition. In addition, various continuous and periodic observations of the major components (such as System Monitoring Walkdowns or Operator Logs) may also support assurance of skid-mounted component readiness. This is acceptable for both Code class components and non-Code class components that are tested and tracked by the 1ST Program."

In the 1996a addenda to the ASME OM Code (endorsed by 10CFR50.55(a) in October 2000), the term skid-mounted was clarified by the addition of ISTA paragraph 1.7:

!STA 1.7 Definitions Skid mounted components and component subassemblies - components integral to or that support operation of major components, even though these components may not be located directly on the skid. In general, these components are supplied by the manufacturer of the major component. Examples include: diesel skid-mounted fuel oil pumps and valves, steam admission and trip throttle valves for high-pressure coolant injection or Auxiliary Feedwater turbine-driven pumps, and solenoid-operated valve provided to control the air-operated valve.

This definition was further clarified in the 1998 and later Editions of the ASME Code:

ISTA-2000 DEFINITIONS Revision Date: November 25, 2020 IST-BRW-PLAN

Skid mounted pumps and valves - pumps and valves integral to or that support operation of major components, even though these components may not be located directly on the skid.

In general, these pumps and valves are supplied by the manufacturer of the major component.

Examples include:

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

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

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

POSITION:

The ASME OM Code definition of skid mounted will be used for classification of components in the Braidwood Station Inservice Testing Program. In addition, for a component to be considered skid mounted:

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

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

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

Revision Date: November 25, 2020 IST-BRW-PLAN

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

VAL VE TECHNICAL POSITION TP-VA-1 TITLE:

Method of Stroke Timing Valves VALVES AFFECTED:

Power Operated Valves Requiring Stroke Time Testing CODE REOUIREMENT{S)/DISCUSSION:

The use of the control board open and closed lights to determine the stroke time of power-operated valves is the issue discussed in this Technical Position. ASME OM Code, Subsection ISTC-2000, defines "full-stroke time" as "the time interval from initiation of the actuating signal to the indication of the end of the operating stroke." It is common industry practice to measure stroke time as the time interval between placing the operator switch on the control board in the "close" or "open" position and indication that the valve is open or closed on the control board (switch to light).

POSITION:

The way in which the limit switches that operate the remote position indicator lights are set may result in "closed" or "open" indication before the valve obturator has actually completed its travel. This is not considered to be a problem, as the purpose of the test is to determine if degradation of the valve operator system is occurring, which is determined by observing changes in stroke time relative to the reference stroke time. Stroke time measurements may be rounded to the nearest tenth (0.1) of a second. Standard rounding techniques are to be used when rounding stop watch readings during valve stroke time testing (e.g., 10.45 rounds to 10.5 and 10.44 rounds to 10.4). Reference values will be established to the nearest tenth of a second although stroke times may be recorded to the hundredths place (0.01 ). This technique satisfies ISTC-5000 Specific Testing Requirements, in that all power operated valves will be measured to at least the nearest second.

For those specific cases in which a valve must be stroke timed locally, the stroke timing will begin with the initiation of the actuating signal and end with the completion of valve movement in the field.

VAL VE TECHNICAL POSITION TP-VA-2 TITLE:

Method of Fail Safe Testing Valves.

VALVES AFFECTED:

See 1ST Valve Tables (FC = Fail Safe Test closed; FO = Fail Safe Test open)

CODE REOUIREMENT(S)/ DISCUSSION:

Subsection ISTC-3560 states that "Valves with fail-safe actuators shall be tested by observing the operation of the actuator upon loss of valve actuator power in accordance with the exercising frequency of ISTC-3510.

POSITION:

Most valves with fail-safe positions have actuators that use the fail-safe mechanism to stroke the valve to the fail-safe position during normal operation. For example, an air-operated valve that fails closed may use air to open the valve against spring pressure. When the actuator is placed in the closed position, air is vented from the diaphragm and the spring moves the obturator to the closed position.

In the cases where normal valve operator action moves the valve to the closed position by de-energizing the operator electrically, by venting air or both (e.g., an electric solenoid in the air system of a valve operator moves to the vent position on loss of power), no additional fail-safe testing is required. Valves with fail-safe actuators that do not operate as part of normal actuator operation must be tested by other means.

Using a valve remote position indicator as verification of proper fail-safe operation is acceptable, provided the indicator is periodically verified to be operating properly as required by ISTC-3700.

The fail-safe test is generally performed at the same frequency as the stroke time exercise test.

Where the exercise test is performed less frequent than every 3 months, a cold shutdown justification, refueling outage justification, or reliefrequest has been written. The same justifications for the stroke timing would also apply to the fail-safe tests.

Method of Remote Position Indication Testing VALVES AFFECTED:

All Motor-Operated Valves tested per Mandatory Appendix Ill CODE REOUIREMENT(S) /DISCUSSION:

Subsection IIl-3300, states that "remote position indication shall be verified locally during inservice testing or maintenance activities."

POSITION:

Remote Position Indication (RPI) for Motor-Operated Valves (MOY) is "sensed" by limit switches (LS) located inside the closed MOY LS compartment. There are small sealed LS gearboxes gear-connected to the actuator wonnshaft. Each LS gearbox drives an output rotor that makes/breaks the electrical contacts on the fingerboards. The lll-3300 RPI test means to accomplish two things; that the RPI functions (i.e., no bad bulbs) AND that the RPI accurately reflects valve position.

Inservice Testing, also called Diagnostic Testing (DIAG), is performed on MOV's in accordance with III-6000. A MOY DIAG is required to be performed at intervals not to exceed 10 years.

Remote Position Indication (RPI) verification will be performed as part of all MOY Diagnostic Testing (DIAG). In addition, RPI verification will be performed as needed following applicable maintenance activities.

Tamminga (ComEd), dated November 14, 1988, concerning Inquiry number IN88-015, the following question was answered:

Question: Is it the intent of Section XI, IWV-3300 that for valves having remote position indicators at multiple locations (such as in the control room and also on a remote shutdown panel and/or sampling panel) that only the remote position indicator at the location utilized in exercising the valve (IWV-3412) and timing the stroke of the valve (IWV-3413) be verified that the valve operation is accurately indicated?

Reply: Yes This Inquiry also applies to the applicable sections in ASME OM Code ISTC:

I. ISTC-3520, Exercising Requirements

2. ISTC-3700, Position Verification Testing

3. ISTC-5000, Specific Testing Requirements In summary, the remote position indicator utilized during valve exercising (ISTC-3520) and stroke timing (ISTC-5000) is the indicator which is used to verify that valve operation is accurately indicated (ISTC-3700).

Revision Date: November 25, 2020 IST-BRW-PLAN

VAL VE TECHNICAL POSITION TP-VA-4 (continued)

The remote position indication test is to be performed as follows:

An individual is dispatched to the valve to locally observe the valve movement and he/she establishes communication with an individual at the remote position indicator. As the valve is exercised in both directions, the individual at the remote position indicator verifies that the indicator shows the proper position by communicating with the local observer, who is observing the valve stem movement. When the valve stem movement cannot be directly observed, indirect means may be employed to verify the change in valve position. These may include observations such as changes in system pressure or establishment/cessation of flow.

VAL VE TECHNICAL POSITION TP-VA-5 TITLE:

Disassembly and Examination of check valves to verify the open and closed exercise capability.

CODE REQUIREMENT(S)/DISCUSSION:

ASME OM Code 2012 Edition, "Code for Operation and Maintenance of Nuclear Power Plants,"

governs this issue. Subsection ISTC-5221 (c), states the following:

"If the test methods in ISTC-5221 (a) and ISTC-5221 (b) 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".

Subsection ISTC-5221 (c )(2) further states that:

"During the disassembly process, the full-stroke motion of the obturator shall be verified.

Full-stroke motion of the obturator shall be reverified prior to completing reassembly".

In addition, ISTC-5221 (c)(4) requires the following:

"Before return to service, valves that were disassembled for examination or that received maintenance that could affect their performance, shall be exercised full- or part-stroke, if practicable, with flow ... "

Background:

Generic Letter 89-04, Position 2, Alternative to Full-flow Testing of Check Valves was issued by the NRC to allow disassembly and examination of check valves as an alternative to the traditional Code requirements for exercising check valves. The NRC staff position in the GL is that valve disassembly and inspection can be used as a positive means of determining that a valve's disk will full-stoke exercise open or of verifying closure.

The 1995 and later editions of the ASME OM Code have incorporated an alternative to the traditional requirements for check valve testing by allowing Owners to establish a Check Valve Condition Monitoring Program. Once a check valve or group of check valves is placed in to the Condition Monitoring Program, the rules of ISTC-5221, Valve Obturator Movement, no longer apply.

Activities and intervals are established within the Check Valve Condition Monitoring Program outside of the frequency requirements ofISTC. As a note, activities such as disassembly/examination may be used within this program for check valves which may be difficult or impossible to test. If a check valve or group of valves is removed from the Condition Monitoring Program for any reason, the valves shall be required to be tested in accordance with the ISTC requirements.

Revision Date: November 25, 2020 IST-BRW-PLAN

VAL VE TECHNICAL POSITION (Contd.)

TP-VA-5 Braidwood Station has adopted this alternative for Check Valve Condition Monitoring. Typically, valves which are disassembled and examined for 1ST purposes are included in this program as well as other check valves which are difficult to test or have had poor performance.

POSITION:

When using disassembly and examination to determine the necessary check valve obturator movement in accordance with ISTB-5221, Braidwood station will determine the full stroke exercise open and closure capability of each check valve.

Braidwood station will verify the Open and Closed functions of each check valve which is disassembled and examined for IST purposes within the Check Valve Condition Monitoring Program or in accordance with ISTC-5221 if the valve is not included in the Condition Monitoring Program. The open and closed function satisfies the bi-directional test requirements for check valves whether they are in Condition Monitoring or not.

If an IST check valve is disassembled or if maintenance is performed outside of the Condition Monitoring program, the valve will be exercised with flow, if practicable prior to returning the valve to service. In this case, a justification for not performing a full or part-stroke of the valve following disassembly or maintenance is required to be documented in the appropriate 1ST Bases Document.

Revision Date: November 25, 2020 IST-BRW-PLAN

VALVE TECHNICAL POSITION TP-VA-6 TITLE:

Testing of Valves with both active and passive safety functions VALVES AFFECTED Power operated valves requiring stroke time testing CODE REQUIREMENT(S)/DISCUSSION:

The 1ST Program requires valves to be exercised to the position(s) required to fulfill their safety function(s). In addition, valves with remote position indication shall have their position indication verified. The Code does not restrict position indication verification to active valves only.

POSITION:

Several valves included in the plant are designed to perform passive safety functions during accident conditions and then based on plant accident response are designed to change positions to perform another (active) function. Once in their final position, there exists no conditions in which they would be required to be placed in their original passive position.

These valves are typically emergency core cooling system valves which require changing position during different phases of the accident. After the original source of injection water is depleted (R WST), the valves are positioned to allow injection from another source (containment sump). The valves are never returned to their original position.

Based on ASME Inquiry OMI 98-07, these valves with passive functions in one direction and active in the other, will be exercised to only their active position. If these valves have position indication, the position indication verification will include verification of both positions.

VAL VE TECHNICAL POSITION TP-VA-7 TITLE:

Classification of Skid Mounted Components PURPOSE:

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

BACKGROUND:

The ASME Code allows classification of some components as skid mounted when their satisfactory operation is demonstrated by the satisfactory performance of the associated major components.

Testing of the major component is sufficient to satisfy Inservice Testing requirements for skid mounted components. In section 3 .4 of NU REG 1482 Revision 2, the NRC suppo1is the designation of components as skid mounted:

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

In the 1996a addenda to the ASME OM Code (endorsed by 10CFR50.55 (a) in October 2000), the term skid-mounted was clarified by the addition ofISTA paragraph 1.7:

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

This definition was further clarified in the 1998 and 2001 Editions of the ASME Code:

ISTA-2000 DEFINITIONS Skid mounted pumps and valves - pumps and valves integral to or that support operation of major components, even though these components may not be located directly on the skid.

In general, these pumps and valves are supplied by the manufacturer of the major component.

Revision Date: November 25, 2020 IST-BRW-PLAN

VALVE TECHNICAL POSITION (Contd.)

TP-VA-7 Examples include:

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

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

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

POSITION:

The ASME OM Code definition of skid mounted will be used for classification of components in the Braidwood Station Inservice Testing Program. In addition, for a component to be considered skid mounted:

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

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

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

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

VAL VE TECHNICAL POSITION TP-VA-8 TITLE:

Non-Safety Function, Check Valve Exercise Testing By Normal Operations PURPOSE:

The purpose of this Technical Position is to establish the position for the verification of the non-safety exercise testing of check valves by normal plant operations. This position is applicable to check valves in the Inservice Testing (1ST) Program as related to the ASME OM Code 2012 Edition.

Applicability This Technical Position is NOT applicable to testing the safety function (position) of IST Check Valves. Safety function here means the function of the valve that meets a scoping requirement to be in the IST Program. This Technical Position is applicable to testing the non-safety function (position) of IST check valves. This Technical Position is applicable to check valves tested under Subsection ISTC, and to Appendix II (Condition Monitoring), of the ASME OM Code 2012 Edition.

BACKGROUND:

The ASME OM Code 2012 Edition, Subsection ISTC, ISTC-3550, "Valves in Regular Use," states the following:

"Valves that operate in the course of plant operation at a frequency that would satisfy the exercising requirements of this Subsection need not be additionally exercised, provided that the observations otherwise required for testing are made and analyzed during such operation and recorded in the plant record at intervals no greater than specified in ISTC-351 O."

ISTC-3510 indicates that check valves shall be exercised nominally every 3 months with exceptions (for extended exercise periods) referenced.

ISTC-522l(a)(2) states that, "Check valves that have a safety function in only the open direction shall be exercised by initiating flow and observing that the obturator has traveled to either the full open position or to the position required to perform its intended function(s) (see ISTA-1100), and verify closure."

Revision Date: November 25, 2020 IST-BRW-PLAN

VALVE TECHNICAL POSITION (Contd.)

TP-VA-8 ISTC-522l(a)(3) states that, "Check valves that have a safety function in only the close direction shall be exercised by initiating flow and observing that the obturator has traveled to at least the partially open position 3 , and verify that on cessation or reversal of flow, the obturator has traveled to the seat" Footnote 3 to this section indicates that the partially open position should correspond to the normal or expected system flow. NOTE: "Normal or expected," system flow rate may vary with plant conditions and configurations. The open safety function of a check valve usually requires meeting a specified, required limiting accident flow rate. As Operators are trained in recognizing normal plant conditions, Operator judgment is acceptable in ascertaining whether the non-safety open check valve position is providing normal or expected flow rates or plant conditions.

As stated in these two sections the non-safety function is satisfactorily demonstrated by verifying closure, or passing normal or expected flow to verify opening, as applicable.

POSITION:

Verification of the non-safety position of 1ST check valves may be performed through the execution of a dedicated surveillance. Alternately this verification may be satisfied as follows:

• An appropriate means shall be determined which establishes how the open/closed non-safety function of the specified check valve is demonstrated during normal operations. The position determination may be by direct indicator, or by other positive means such as changes in system pressure, flow rate, level, temperature, seat leakage, etc. This determination shall be documented in the respective Condition Monitoring Plan in the "Bases for Testing and Inspection Strategy," for valves in the Condition Monitoring Program. For check valves governed by Subsection ISTC and not in Condition Monitoring this determination shall be documented in the respective 1ST Bases Document valve group in the "Bases Statement," section.

• Automated processes may be used to provide for the "observation and analysis," that a check valve is appropriately satisfying its non-safety position function. An example of this would be a check valve that has a safety function in only the close direction and normally has flow through it to maintain normal plant operations. If the check valve is not opening to pass flow, alarms or indications would identify the problem to the Operator who is trained to respond to such situations and take appropriate actions. Issue Reports are normally written for abnormal plant conditions attributable to material condition concerns such as check valve failures.

Revision Date: November 25, 2020 IST-BRW-PLAN

VAL VE TECHNICAL POSITION (Contd.)

TP-VA-8

• The "observation and analysis," of logs and other such records is satisfied by Operator reviews. Operating personnel are trained to look for off-normal data and adverse trends and take actions as appropriate. This would effectively determine if a check valve were satisfactorily fulfilling its' non-safety function.

• The open/closed non-safety function shall be recorded at a periodicity required by ISTC-3510, with exceptions as provided, in plant records such as Operator logs, Electronic Rounds, chai1 recorders, automated data loggers, etc. NOTE: The safety function testing of these valves constitutes requiring a Quality Record. Records as indicated above are appropriate for the non-safety testing. Should any concerns arise regarding the material condition/operation of these check valves an Issue Repo11 is written which is a Quality Record. The method in which the check valve position is recorded shall be included in the Condition Monitoring Plan or Bases Document sections as indicated above.

Justification This Technical Position requires that the method of determining the non-safety position be established. The plant systems and Operator actions provide for the observations and analysis that the valve is satisfying its non-safety function. Finally, the recording and analyzing of parameters demonstrating valve position is satisfied at a frequency specified in ISTC-3510. These actions collectively satisfy demonstrating the non-safety position of 1ST check valves in regular use as required by ISTC-3550.

VAL VE TECHNICAL POSITION TP-VA-12 TITLE:

Bases for testing series check valves 1RH8705A and 1RH8706A as a unit.

VALVES AFFECTED:

1RH8705A 1RH8706A CODE REQUIREMENT(S)/DISCUSSION:

ASME OM Code 2012 Edition, "Code for Operation and Maintenance of Nuclear Power Plants,"

governs this issue. Subsection ISTC- 5223, Series Valve Pairs, states the following:

"If two check valves are in a series configuration without provisions to verify individual reverse flow closure (e.g., keepfill pressurization valves) and the plant safety analysis assumes closure of either valve (but not both), the valve pair may be operationally tested closed as a unit.

If the plant safety analysis assumes that a specific valve or both valves of the pair close to perform the safety function(s), the required valve(s) shall be tested to demonstrate individual valve closure."

Subsection ISTC-9200, Test Plans, states the following:

"The Owner shall maintain a record of test plans that shall include the following,"

(Subsection ISTC-9200 (d)), "bases for testing series check valve pairs as a unit in accordance with ISTC-5223."

Bases for series pair testing:

Valves 1RH8705A and 1RH8706A are tested as a series pair because they have no intermediate test taps. These valves were installed in Unit 1 under Engineering Change no. 359951. Valve 1RH8706A was added to the unit, upstream of 1RH8705A in lieu of repairing 1RH8705A in the A1R12 outage. The 1RH8706A provides assurance that backflow through the line will be prevented. In the Modification they were tested as a series pair in the closure test. There is no mention anywhere in the Modification indicating a design requirement to test the valves individually. If there were such a requirement it would need to have been prescribed in the Revision Date: November 25, 2020 IST-BRW-PLAN

VALVE TECHNICAL POSITION (Contd.)

TP-VA-12 Modification and the test executed prior to accepting the Modification. As such, the design allows for the closure of either valve to perform the function of maintaining pressure integrity.

POSITION:

These check valves are in a series configuration without provisions to verify individual reverse flow closure. The Modification that installed the I RH8706A valve allowed for the closure of either valve to perform the function of preventing back.flow. The Modification acceptance test was a closure/leakage test, which tested these valves as a series pair. As such it is appropriate to test these valves as a series pair.

NON COMPONENT SPECIFIC TECHNICAL POSITION TP-NC-1 TITLE:

Deferral Justification Test Window CODE REQUIREMENT(S)/DISCUSSION:

Inservice Test (1ST) Program components which are required to be tested during a refueling outage (RFO) may be tested in conjunction with plant "coast-down" (i.e. a period where a conscious deviation from normal operating temperature and power occurs in conjunction with reactor fuel depletion) as qualified below, or a planned load reduction (e.g. reduction in turbine load via a selected downward ramp rate) intended to take the plant from Mode 1, power operation, to an offline condition, and ultimately to Mode 6, refueling.

The period where the load reduction is accomplished via plant coast-down potentially can encompass a period of weeks before the actual start of an RFO. The existing regulatory guidance for allowing deferral of testing to an RFO is based on the impracticality of being able to perform the test on a quarterly basis. Performing tests which have been deferred to an RFO weeks in advance of the RFO is not in keeping with the spirit of the deferral latitude.

As such, testing being performed to satisfy various 1ST program deferrals, while in plant coast-down, should only take place when the projected end of the coast down window is 120 hours0.00139 days <br />0.0333 hours <br />1.984127e-4 weeks <br />4.566e-5 months <br /> or less. Five working days affords adequate time to accomplish the anticipated limited test scope and is not considered excessive when compared to the intent of the Code deferral allowance.

All IST components required to be tested during a RFO shall have their prescribed test satisfactorily completed and demonstrated operable prior to resumption of power operation and before exceeding the associated Technical Specification Mode of applicability, unless specifically stated otherwise in the Technical Specifications.

Revision Date: November 25, 2020 IST-BRW-PLAN

NON COMPONENT SPECIFIC TECHNICAL POSITION TP-NC-2 TITLE:

On-Line Maintenance CODE REQUIREMENT(S)/DISCUSSION:

The advent of on-line plant maintenance to perform work on safety related components and systems outside of the traditional refueling outage (RFO) time frame, is designed to maximize component/system availability while favorably impacting RFO duration and the associated corporate financial impact. The practice of doing on-line maintenance represents a departure from the norm where the bulk of the maintenance was performed while engaged in an RFO. As such, the Inservice Test Program, which is directed by the ASME Code which does not take into account on-line maintenance practices, can experience implementation issues when on-line preventative maintenance or corrective maintenance is performed.

Typically, a number of Inservice Test Program components can't meet Code based quarterly test frequency due to the practicality of performing the testing. System alignments, operating conditions (pressure, flow, temperature, etc.) and other such restrictions often render the testing impracticable. The Code allows the affected testing to be deferred to a lower plant MODE, from MODE 5, cold shutdown to MODE 6, Refueling. The understanding between the Licensee and the NRC is that such testing will take place in the highest MODE deemed practicable by the Licensee with the assumption that sufficient basis to justify the deferred MODE exists. Contrary to what occurred in the past, the NRC is no longer required to approve such deferrals. As such, along with the deferral comes the expectation that testing can and should only be performed when in the applicable deferred MODE unless extenuating circumstances exist. Performance of on-line maintenance and the need to demonstrate post-maintenance operability for the component/system worked on clearly is an example of an extenuating circumstance given its prevalent implementation and widespread acceptance throughout the nuclear industry.

Inservice Test Program components which have had their associated Code required tests deferred from the normal "during operation at power" time frame, whether to cold shutdown (using a Cold Shutdown Justification (CSJ) or Refueling Shutdown (using a Refueling Outage Justification (ROJ)), may revert back to the at power time fi*ame, on a limited basis, to accomplish post-maintenance operability testing (PMOT) following performance of on-line maintenance provided that:

NON COMPONENT SPECIFIC TECHNICAL POSITION (Contd.)

TP-NC-2 A). The testing that will occur during power operation will not expose plant personnel to unsafe working conditions nor place components or systems in alignments adverse to plant safety.

AND B). One or more of the following maintenance scope activities are desired and serves to justify the performance of deferred testing at the normal at power time frame:

1) Corrective on-line maintenance is desired to be performed on the component to restore the component to the operable condition and testing required to demonstrate component/system post-maintenance operability is contained in the surveillance test(s) used to satisfy the associated 1ST Program Code requirements.

2) Preventative on-line maintenance is desired to be performed on the component to lessen or eliminate RFO time frame system/component unavailability (e.g. performing the maintenance in a plant MODE that poses a lesser or no adverse risk probability to plant safety) and the testing required to demonstrate component/system post-maintenance operability is contained in the surveillance test(s) used to satisfy the associated 1ST Program Code requirements.

The relaxation of the associated CSJ or ROJ is only to be exercised on a limited basis. Limited is defined as not more than once per 18 months (All Braidwood Station Technical Specification surveillance requirements which tie performance to a fuel cvcle frequencv, utilize an 18 month fuel cycle duration) unless additional documented justification is provided in advance of the proposed maintenance. The 1ST Program Engineer must review and concur with such justification before the proposed maintenance can proceed.
