| ATTACHMENT 1 to GNR0-2018/00013 Description and Assessment (9 pages)
| |
| - Description and Assessment GNR0-2018/00013 1.0 Description The proposed amendment would modify Technical Specifications (TS) by relocating specific surveillance frequencies to a licensee-controlled program with the adoption of Technical Specification Task Force (TSTF)-425, Revision 3, "Relocate Surveillance Frequencies to Licensee Control-RITSTF Initiative 5b." Additionally, the change would add a new program, the Surveillance Frequency Control Program, to TS Chapter 5.0, Administrative Controls.
| |
| The changes are consistent with NRC approved lndustry/TSTF Standard Technical Specifications (STS) change TSTF-425, Revision 3, (Rev. 3) (NRC Agencywide Documents Access and Management System (ADAMS) Accession No. ML090850642).
| |
| The Federal Register notice published on July 6, 2009 (74 FR 31996) announced the availability of this TS improvement.
| |
| 2.0 Assessment 2.1 Applicability of Published Safety Evaluation Entergy Operations, Inc. (Entergy) has reviewed the model safety evaluation (SE) provided in Federal Register Notice 74 FR 31996, dated July 6, 2009. This review included the NRC staff's modei SE, TSTF-425, Revision 3, and the requirements specified in NEI 04-10, Revision 1 (NRC ADAMS Accession No. ML071360456).
| |
| Attachment 2 includes Entergy's documentation with regard to the Grand Gulf Nuclear Station, Unit 1 (GGNS) probabilistic risk assessment (PRA) technical adequacy consistent with the requirements of Regulatory Guide 1.200, Revision 2 (NRC ADAMS Accession No. ML090410014), Section 4.2, and describes any PRA models without NRG-endorsed standards, including documentation of the quality characteristics of those models in accordance with Regulatory Guide 1.200.
| |
| Entergy has concluded that the justifications presented in the TSTF proposal and the model SE prepared by the NRC staff are applicable to GGNS and justify this amendment to incorporate the changes to the GGNS TS.
| |
| 2.2 Optional Changes and Variations The proposed amendment is consistent with the STS changes described in TSTF-425, Revision 3; however, Entergy proposes variations or deviations from TSTF-425, as identified below, and include differing TS Surveillance numbers.
| |
| \
| |
| : 1. The definition of STAGGERED TEST BASIS is being retained in the GGNS TS Section 1.1, "Definitions," because this terminology continues to be used in several SR Frequencies which are not the subject of this amendment request and is not proposed to be changed (e.g., SRs 3.4.4.3, 3.5.1.7, and 3.6.1.6.1 ). This is an administrative deviation from TSTF-42~ with no impact on the NRC staffs model SE dated July 6, 2009 (74 FR 32001 ).
| |
| Page 1 of 9
| |
| - Description and Assessment GNR0-2018/00013
| |
| : 2. GGNS SRs with SR numbers that differ from the corresponding TSTF-425 SRs are administrative deviations from TSTF 425 with no impact on the NRC's model SE dated July 6, 2009 (7 4 FR 32001 ).
| |
| : 3. For NUREG-1434 SRs not contained in the GGNS TS, the corresponding mark-ups included in TSTF-425 for these SRs are not applicable to GGNS. This is an administrative deviation from TSTF-425 with no impact on the NRC's model SE dated July 6, 2009 (74 FR 32001 ).
| |
| 4: Plant-specific SRs 3.4.9.2, 3.4.10.2, 3.6.1. 7.2, 3.6.2.3.2, 3.9.8.2, and 3.9.9.2 are not contained in the mark-ups provided in TSTF-425. These SRs were added to the GGNS TS per License Amendment 202 (NRC ADAMS Accession No. ML15104A623), which implements TSTF-523, Revision 2. TSTF-523 allows the option of relocating the applicable SRs to the Surveillance Frequency Control Program (SFCP). For these and other plant-specific SRs identified in Attachment 7 that are not contained in the NUREG-1434 mark-ups provided in TSTF-425, Entergy has determined that the relocation of the frequencies for these GGNS plant-specific SRs is consistent with the intent of TSTF-425, Revision 3, and with the NRC's model SE dated July 6, 2009 (74 FR 32001 ). The subject plant-specific SR frequencies are periodic frequencies and do not meet the scope exclusion criteria identified in Section 1.0, lllntroduction," of the model SE.
| |
| In accordance with TSTF-425, changes to the frequencies for these SRs would be controlled under the SFCP. The SFCP provides the necessary administrative controls to require that SRs related to testing, calibration and inspection are conducted at a frequency to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met. Changes to frequencies in the SFCP would be evaluated using the NRC approved methodology and probabilistic risk guidelines contained in NEI 04-10, Revision 1. This deviation from TSTF-425 is consistent with other industry applications adopting TSTF-425 (e.g., Waterford Unit 3 License Amendment 249 - NRC ADAMS Accession No. ML16159A419, Perry Unit 1 License Amendment 171 - NRC ADAMS Accession No. ML15307A349, and Brunswick Units 1 and 2 License Amendments 276 and 304, respectively - NRC ADAMS Accession No. ML17096A129).
| |
| : 5. The SFCP is added to TS 5.5.6 and the word "Deleted" is removed instead of adding the program at the end of TS Section 5.5. This change is an administrative deviation from TSTF-425 with no impact on the NRC's model SE dated July 6, 2009 (74 FR 32001)
| |
| : 6. Periodic frequencies associated with GGNS TSs 5.5.7, 5.5.9, and 5.5.13 are included in the scope of this amendment that are not identified for relocation in TSTF-425, Revision 3.
| |
| The first paragraph of TS 5.5.7 is revised, in part, as follows (deleted text in strikeout and added text in italics):
| |
| " ... required testing of Engineered Safety Feature (ESF) filter ventilation systems at the frequencies specified in Regulatory Guide 1.52, Revision Page 2 of 9
| |
| - Description and Assessment GNR0-2018/00013 2, except that testing specified at a frequency of 18 months is required at a frequency of 24 months in accordance with the Surveillance Frequency Control Program."
| |
| TS 5.5.9.a is revised as follows (deleted text in strikeout and added text in italics):
| |
| "Acceptability of new fuel oil for use prior to addition to storage tanks, and acceptability of stored fuel oil every 92 daysat a frequency in accordance with the Surveillance Frequency Control Program, by determining that the fuel oil has:"
| |
| TS 5.?.9.c is revised as follows (deleted text in strikeout and added text in italics):
| |
| "Total particulate concentration of the fuel oil in the storage tanks is s 2 mg/100 ml when tested every 92 days in accordance with ASTM D-2274-70 at a frequency in accordance with the Surveillance Frequency Control Program."
| |
| TS 5.5.13.d.5 is revised, in part, as follows (deleted text in strikeout and added text in italics):
| |
| "An assessment of the CRE Boundary will be conducted every 18 monthsat a frequency in accordance with the Surveillance Frequency Control Program."
| |
| Entergy has determined that the relocation of the periodic frequencies associated with these specifications are consistent with the intent of TSTF-425, Revision 3, and with the NRC's model SE dated July 6, 2009 (74 FR 32001 ). The subject TS Section 5.5 frequencies are periodic frequencies and do not meet the scope exclusion criteria identified in Section 1.0, "Introduction," of the model SE. These changes are similar to the SR frequency relocation (i.e., TS 6.5.17.d frequency) to the SFCP that the NRC approved for Waterford Unit 3 License Amendment 249 (NRC ADAMS Accession No. ML16159A419).
| |
| In accordance with TSTF-425, changes to the frequencies for these surveillances would be controlled under the SFCP. The SFCP provides the necessary administrative controls to require that surveillances related to testing, calibration and inspection are conducted at a frequency to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met. Changes to frequencies in the SFCP would be evaluated using the NRC approved methodology and probabilistic risk guidelines contained in NEI 04-10, Revision 1.
| |
| : 7. Entergy proposes combining SR 3.3.1.1.21 and SR 3.3.1.1.22 with SR 3.3.1.1.13 and SR 3.3.1.1.15, respectiv~ly because the proposed changes to SRs 3.3.1.1.21 and 3.3.1.1.22 and the changes to SRs 3.3.1.1.13 and 3.3.1.1.15 result in the two pairs of SRs being the same. SRs 3.3.1.1.21 and 3.3.1.1.22 were added to the TS pursuant License Amendment 188, dated March 28, 2012 (NRC ADAMS Accession No. ML120400319), as part of the power range neutron monitoring system digital upgrade, both with a frequency of 24 months. Later, the frequency of SRs 3.3.1.1.*13 and 3.3.1.1.15 was modified from 18 months to 24 months pursuant License Amendment 197, dated December 26, 2013 (NRC ADAMS Accession No. ML13343A109), to support operation with a 24 month fuel cycle. Entergy proposes Page 3 of 9
| |
| - Description and Assessment GNR0-2018/00013 the deletion of SRs 3.3.1.1.21 and 3.3.1.1.22 rather than maintaining redundant TS SRs that accomplish the same function. Also, resultant changes are made to the SR references associated with Function 2.e in Table 3.3.1.1-1 as shown in the markup of the TS page (Attachment 3). In addition, as a result of the power range neutron monitoring system digital upgrade approved in License Amendment 188, TS 3.3.1.3 was deleted. Therefore, TS Pages 3.3-13a and 3.3-13b are being removed.
| |
| Combining SR 3.3.1.1.21 with SR 3.3.1.1.13 and SR 3.3.1.1.22 with SR 3.3.1.1.15 and removing Pages 3.3-13a and 3.3-13b does not alter the intent of the current SRs nor does the change have an adverse impact on the proposed amendment. This change is an administrative deviation from TSTF-425 with no impact on the NRC's model SE dated July 6, 2009 (7 4 FR 32001 ).
| |
| : 8. In the process of incorporating SR reference changes to Function 2.e in Table 3.3.1'.1-1, several Functions have been moved to the following pages and footnotes re-annotated, adding the appropriate footnote(s) at the bottom of each page per the guidance of Section 2.1.9 of the TSTF-GG-05-01, Writer's Guide for Plant-Specific Improved Technical Specifications, June 2009 (ISTS Writer's Guide), consistent with NUREG-1434 Table 3.3.1.1-1 format, as shown in the markup of the TS page (Attachment 3). These proposed formatting changes do not alter any technical content on the associated pages and therefore, are considered an administrative deviation from TSTF-425 with no impact on the NRC's model SE dated July 6, 2009 (74 FR 32001 ).
| |
| : 9. NRC letter dated April 14, 2010 (NRC ADAMS Accession No. ML100990099),
| |
| provides a change to an optional insert (Insert #2) to the existing TS Bases to facilitate adoption of the Traveler. The TSTF-425 TS Bases insert states the following:
| |
| "The Surveillance Frequency is based on operating experience, equipment reliability, and plant risk and is controlled under the Surveillance Frequency Control Program."
| |
| This statement only applies to frequencies that have been changed in accordance with the SFCP and does not apply to frequencies that are relocated but not changed.
| |
| Consistent with NUREG-1434, Revision 4 (NRC ADAMS Accession No. ML12104A195), Entergy has replaced the TSTF-425 TS Bases Insert #2 with the following variations based on the context of the specific Bases:
| |
| Individual SR Bases -
| |
| "The Surveillance Frequency is controlled under the Surveillance Frequency Control Program."
| |
| Multiple SR Bases -
| |
| "The Surveillance Frequencies are controlled under the Surveillance Frequency Control Program."
| |
| SR Bases containing additional frequencies not controlled in the SFCP -
| |
| Page 4 of 9
| |
| - Description and Assessment GNR0-2018/00013 "The time interval based Surveillance Frequency[ies] is[are] controlled under the Surveillance Frequency Control Program."
| |
| SR Bases based on TSTF-523 -
| |
| "The Surveillance Frequency is controlled under the Su-rveillance Frequency Control Program. The Surveillance Frequency may vary by location susceptible to gas accumulation."
| |
| This administrative deviation from TSTF-425 does not alter the intent of the proposed amendment and does not impact on the NRC's model SE dated July 6, 2009 (74 FR 32001 ).
| |
| : 10. Due to the relocation of SR frequencies and replacing them with "In accordance with the Surveillance Frequency Control Program," there are multiple SRs that moved to the next page requiring further formatting as identified in the markup of the TS pages (Attachment 3). The following new pages are added as a result of these formatting revisions:'pages 3.1-24, 3.2-3, 3.4-18a, 3.5-Sa, 3.6-23a, 3.7-16, 3.9-11a, and 5.0-16b. Additionally, minor formatting errors have also been corrected as identified in the markup of the TS pages (Attachment 3). For examples; deletion of unnecessary use of the article "the" in several SRs in accordance with Section 3.1.1.e of the ISTS Writer's Guide; capitalization of "NOTE" and "MODE" as applicable in accordance with Section 3.3.2 of the ISTS Writer's Guide; and aligning the Frequency for several SRs to align with the SR text consistent with NUREG-1434 and in accordance with Section 2.5 of the ISTS Writer's Guide. The following summarizes the formatting corrections:

| Page 6 of 9
| |
| - Description and Assessment GNR0-2018/00013 The formatting changes, as summarized herein and identified in the markup of the TS pages (Attachment 3), are administrative deviations from TSTF-425 with no impact on the NRC's model SE dated July 6, 2009 (74 FR 32001 ).
| |
| : 11. The SR row associated with SR 3.6.1.9.2 is removed because the associated SR has been deleted in a previous license amendment and is no longer needed.
| |
| Subsequent SR is renumbered. fn addition, TS pages 3.3-74, 3.3-76, 3.4-5, 3.6-35/3.6-36, 3.8-17, and 3.8-25 are deleted because the information on these pages was deleted in previous license amendments and, as a result, the pages are no longer needed. As a result, a note is added in the footer of the preceding pages, as applicable, to state the next page number. This eliminates the need to renumber the .
| |
| subsequent pages. TS page 3.3-75 is renumbered to page 3.3-74. Deleting the SR rows and unnecessary pages does not have an adverse impact on the proposed amendment. These formatting changes do not alter the technical content or the way the TSs are applied, and are administrative deviations from TSTF-425 with no impact on the NRC's model SE dated July 6, 2009 (74 FR 32001 ).
| |
| : 12. Logical connector "AND" is added to SR 3.2.2.2 frequencies to separate them consistent with Section 1.2, "Logical Connectors," and similar to SR 3.1.7.5 frequencies. The logical connectors were inadvertently omitted in License Amendment 191 (NRC ADAMS Accession No. ML121210020). SR 3.2.2.2 was added to the GGNS TSs as part of the extended power uprate. As identified in Section 4.1.8 of Attachment 1 to the GGNS extended power uprate LAR (NRC ADAMS Accession No. ML102660403), each Frequency is required as identified with the grammaticar conjunction "and." This proposed formatting change restores the intent of the frequencies. As a result, SR 3.2.2.2 is moved to Page 3.2-3 and the follqwing page is renumbered. In addition, current pages 3.2-4 through 3.2-6 are deleted since the related information was previously deleted in License Amendment 188 (NRC ADAMS Accession No. ML120400319). These formatting changes are administrative deviations from TSTF-425 with no impact on the NRC's model SE dated July 6, 2009 (74 FR 32001 ).
| |
| : 13. The Frequency of SR 3.4.4.3, SR 3.5.1. 7, and SR 3.6.1.6.1 are revised to capitalize lnservice Testing Program consistent with the intent of TSTF-545, Revision 3, "TS lnservice Testing Program Removal & Clarify SR Usage Rule Application to Section 5.5 Testing," which was adopted in License Amendment 211 (NRC ADAMS Accession No. ML16140A133). Adoption ofTSTF-545 removed the lnservice Testing Program from TS Section 5.5 and added a definition, INSERVICE TESTING PROGRAM, in TS Section 1.1, which included capitalizing existing uses of the term "lnservice Testing Program" throughout the TS. This typographical change is an administrative deviation from TSTF-425 with no impact on the NRC's model SE dated July 6, 2009 (74 FR 32001 ).
| |
| : 14. The format of TS 3.7.7, "Main Turbine Bypass System," is revised to be consistent
| |
| ( with NUREG-1434, Revision 4, TS 3.7.6, "Main TL~rbine Bypass System," in accordance with the ISTS Writer's Guide as shown in the markup of the TS pages (Attachment 3). The bracketed information provided in NUREG-1434, Action A was not intended to be added in it's entirety; rather it was intended to provide a choice of wording based on whether the optional portion of the associated LCO was adopted (e.g., Clinton TS 3.7.6 (NRC ADAMS Accession No. ML052720312)). The format Page 7 of 9
| |
| - Description and Assessment GNR0-2018/00013 change does not alter the technical content or the way the TS is applied, and is an administrative deviation from TSTF-425 with no impact on the NRC's model SE dated July 6, 2009 (74 FR 32001 ).
| |
| Entergy proposes to relocate surveillance frequencies except those that reference other approved programs, are purely event-driven, are event-driven but have a time component for performing the surveillance on a one-time basis once the event occurs, or are related to specific conditions. Entergy considers the differences listed herein to be minor variations or deviations of the type permitted by TSTF-425.
| |
| Attachment 7 provides a cross-reference between the NUREG-1434 SRs included in TSTF-425 versus GGNS TS. This attachment includes a summary description of the referenced TSTF-425/GGNS TS SRs which is being provided for information purposes only and is not intended to be a verbatim description of the TS SRs. This cross-reference highlights the following:
| |
| * NUREG-1434 SRs included in TSTF-425 and corresponding GGNS TS SRs with plant-specific surveillance numbers;
| |
| * NUREG-1434 SRs not included in TSTF-425 that meet TSTF criteria for frequency relocation and corresponding GGNS TS surveillances with plant-specific surveillance numbers, as applicable;
| |
| * NUREG-1434 SRs included in TSTF-425 that are not contained in the GGNS TS; and
| |
| * GGNS plant-specific TS surveillances that meet TSTF criteria for frequency relocation but are not contained in either NUREG-1434 or markups in TSTF-425.
| |

| |
| : 1. PURPOSE The purpose of this report is to document the technical adequacy of the Grand Gulf Nuclear Station (GGNS) Probabilistic Risk Assessment (PRA) model to support the implementation of the Surveillance Frequency Control Program (SFCP), also referred to as Technical Specifications Initiative 5b (Reference 1). GGNS will follow the guidance provided in NEI 04-10, Revision 1 (Reference 2), in evaluating proposed surveillance test interval (STI) changes (also referred as "surveillance frequency" changes).
| |
| : 2. SCOPE As explained in NEI 04-10, the Technical SpecifiGations Initiative 5b uses a risk-informed, performance based approach for establishment of the surveillance frequencies, where PRA methods are used to determine the risk impact of the revised intervals. The PRA technical adequacy is addressed through NRC Regulatory Guide (RG) 1.200 (Reference 3), which references the ASME/ANS PRA standard, RA-Sa-2009 (Reference 4 ), for internal events at power. Risk impacts associated with fire, seismic, external events, and shutdown activities may be considered quantitatively or qualitatively.
| |
| NEI 04-10 guida11ce includes the five key safety principles described in RG 1.174 (Reference 5),
| |
| which are followed as part of this risk-informed Technical Specification Interval change program.
| |
| The five key safety principles are:
| |
| : 1. Change meets current regulations unless it is explicitly related to a requested exemption or rule change
| |
| : 2. Change is consistent with defense-in-depth philosophy
| |
| : 3. Maintain sufficient safety margins
| |
| : 4. Proposed increases in core damage frequency (CDF) or risk are small and consistent with the Commission's Safety Goal Policy Statement
| |
| : 5. Use performance-measurement strategies to monitor the change The GGNS PRA model Revision 4a is the current model of record for GGNS (Reference 6).
| |
| This model and its technical content was constructed and documented to meet the ASME/ANS PRA standard (Reference 4). The PRA model quantification methodology used at Entergy Operations, Inc. (Entergy), nuclear sites is common and well-known to the industry.
| |
| Entergy's approach for maintaining, updating and documenting the PRA models at all Entergy nuclear sites is controlled in the fleet procedures. These procedures are consistent with the guidance of the ASME/ANS PRA standard (Reference 4). The procedural process is comprehensive and detailed, which in turn provides the basis for establishing and maintaining the technical adequacy of the models, as well as ensuring the models reflect the as-built, as-operated plant configuration of the sites. In addition, self-assessments and independent peer reviews are also utilized by Entergy, which reassures the confidence in the approach and overall adequacy of the models against the recognized industry sta.ndards and methodologies.
| |
| | |
| ENTCORPSO-GGNS-01, Rev. 0 GGNS PRA Technical Adequacy Page 6 of 17 Sections 2.1 and 2.2 describe the general change process and PRA adequacy requirements, respectively, required to support the Initiative Sb. Section 3 documents the technical adequacy of the GGNS PRA model specifically.
| |
| 2.1. Surveillance Frequency Change Process NEI 04-10 describes the required steps to be followed to adjust an STI. A summary i~ presented below. *
| |
| * Once the STI requiring adjustment is selected, NRC regulatory commitments are collected and reviewed. If any prohibitive commitments are identified, such are examined to determine if the commitment can be changed. If there are no prohibitive commitments, or the commitments may be changed using a commitment change process based on NRC endorsed guidance, then evaluation of the STI revision proceeds. If a regulatory commitment exists and the commitment change process does not permit the change, then the STI revision is not implemented (NEI 04-10, Steps 0-4 (Reference 2)).
| |
| * The PRA technical adequacy is evaluated using guidance from RG 1.200 (Reference 3).
| |
| The RG addresses the need to evaluate important assumptions that relate to key modeling uncertainties (such as reactor coolant pump seal models, common cause failure methods, success path determinations, human reliability assumptions, etc.).
| |
| Further, the RG addresses the need to evaluate parameter uncertainties and demonstrate that calculated risk metrics (i.e., CDF and large early release frequency (LERF)) represent mean values. The identified "gaps" to Capability Category II requirements from the endorsed PRA standards in the RG and the identified key sources of uncertainty serve as inputs to identifying appropriate sensitivity cases (NEI 04-10, Step 5 (Reference 2) ).
| |
| * Select the revised STI value and revise any changes to the test strategy (NEI 04-10, Step 6 (Reference 2) ).
| |
| * Qualitative considerations or qualitative analyses are developed for the STI revision.
| |
| Qualitative considerations include surveillance test and performance history, past industry and plant-specific experience, impact on defense-in-depth protection, among other considerations (NEI 04-10, Step 7 (Reference 2)).
| |
| * Perform quantitative and/or qualitative PRA assessments. Steps 8 through 12 in NEI 04-10 (Reference 2) provide details regarding the use of PRA for evaluating the STI. The use of the PRA includes: determining if the structures, systems, and components (SSCs) in question are modeled in the PRA, whether the SSCs or operator actions can be modeled (and make changes to the model if possible) or not, perform qualitative assessments as needed, evaluate total and cumulative effect on CDF and LERF, and perform sensitivity studies as needed.
| |
| * The results and proposed STI changes are documented and summarized for consideration by the Integrated Decision-making Panel (IDP). The IDP is usually comprised of the site Maintenance Rule expert panel, a surveillance test coordinator and a subject matter expert. The IDP approves or rejects the STI changes (with the possibility of adjustments if applicable). If the IDP approves the STI changes, these are documented and implemented. The IDP is also responsible for reviewing the
| |
| | |
| ENTCORPSO-GGNS-01, Rev. 0 GGNS PRA Technical Adequacy Page 7 of 17 performance monitoring results and providing feedback if the STI changes, once implemented, result in unsatisfactory performance (NEI 04-10, Steps 16-20 (Reference 2)).
| |
| 2.2. Technical Adequacy of a PRA As previously discussed, NEI 04-10 (Reference 2) endorses the guidance of the NRC Regulatory Guide 1.200 (Reference 3) for the PRA technical adequacy determination. For the purposes of this report, Section 4.2 of RG 1.200 is used in support of Initiative 5b licensee applications. It is important to note that the scope of Initiative 5b applications is broad, and PRA assessments needed for each application vary from application to application. The following requirements are noted in Section 4.2 as necessary to demonstrate that the technical adequacy of the PRA is of sufficient quality to support the application submittal:
| |
| : 1. To address the need for the PRA model to represent the as-designed or as-built, as-operated plant.
| |
| : 2. Identification of permanent plant changes (such as design or operational practices) that have an impact on those SSCs modeled in the* PRA but have not been incorporated in the baseline PRA model. If a plant change has not been incorporated in the PRA, the licensee provides a justification of why the change does not impact the PRA results used to support the application. This justification should be in the form of a sensitivity study that demonstrates the accident sequences or contributors significant to the application decision were not adversely impacted (remained the same).
| |
| : 3. Documentation that the parts of the PRA required to produce the results used in the decision are performed consistently with the standard as endorsed in the appendices of the RG. If a requirement of the standard (as endorsed in the appendix to the RG) has not been met, the licensee is to provide a justification of why it is acceptable that the requirement has not been met. This justification should be in the form of a sensitivity study that demonstrates the accident sequences or contributors significant to the application were not impacted (remained the same).
| |
| : 4. A summary of the risk assessment methodology used to assess the risk of the application, including how the base PRA model was modified to appropriately model the risk impact of the application and results. (Note that this is the same as that required in the application-specific regulatory guides.) *
| |
| : 5. Identification of the key assumptions and approximations relevant to the results used in the decision-making process. Also, include the peer reviewers' assessment of those assumptions. These assessments provide information to the NRC staff in their determination of whether the use of these assumptions and approximations is appropriate for the application, or whether sensitivity studies performed to support the decision are appropriate.
| |
| : 6. A discussion of the resolution of the peer review (or self-assessment, for peer reviews performed using the criteria in NEI 00-02) facts and observations that are applicable to the parts of the PRA required for the application. This discussion should take the following forms:
| |
| | |
| ENTCORPSO-GGNS-01, Rev. 0 GGNS PRA Technical Adequacy Page' 8 of 17
| |
| * a discussion of how the PRA model has been changed,
| |
| * a justification in the form of a sensitivity study that demonstrates the accident sequences or contributors significant to the application decision were not adversely impacted (remained the same) by the particular issue.
| |
| : 7. The standards or peer review process documents may recognize different capability categories or grades that are related to level of detail, degree of plant specificity, and degree of realism. The licensee's documentation is to identify the use of the parts of the PRA that conform to capability categories or grades lower than deemed required for the given application (Section 1-3 of ASME/ANS RA-Sa-2009 (Reference 4)).
| |
| This PRA technical adequacy report addresses the quality of the PRA to support relocation of STI frequencies to a licensee controlled document. There are no STI changes proposed for this Initiative Sb application. Items 3 and 4, above, are addressed when preparing an STI change request and are, therefore, not covered in this report. The remaining items above are discussed in Section 3.
| |
| : 3. GGNS PRA TECHNICAL ADEQUACY 3.1. Discussion The GGNS PRA models are controlled in accordance with Entergy procedures consistent with the requirements provided in the ASME/ANS PRA Standard (Reference 4), as previously stated in Section 2. Entergy procedures define the process to be followed to implement scheduled and interim PRA model updates and to control the PRA model files. In addition, the procedur~ also defines the process for identifying, tracking and implementing model changes, and for identifying and tracking model improvements or potential issues that may affect the model.
| |
| Model changes t.hat are identified are tracked via model change requests (MCRs), which are entered in the Entergy MCR database.
| |
| Periodic PRA model updates are typically performed at least once every four years, with the option of extending the frequency for up to an additional two years, such that the total update period does not exceed six years. Extensions are justified by showing that the PRA model continues to adequately represent the as-built, as-operated plant and must be approved by management.
| |
| The GGNS PRA model Revision 4a was approved in October 2017 (Reference 6). GGNS
| |
| ., models follow the guidelines of RG 1.200. Section 3.2 discusses the requirements in RG 1.200 to demonstrate PRA technical adequacy as applicable to the current GGNS internal events and internal flooding models.
| |
| The GGNS PRA model Revision 4a is the baseline model of record as of the completion of the 2017 finding closure independent assessment. No changes have been made to the Revision 4a PRA model of record since the completion of the independent assessment. Refer to Section 3.2.2 herein for further discussion of the 2017 independent assessment.
| |
| GGNS does not currently have a fire PRA model developed in accordance with NUREG/CR-6850 (Reference 7). Section 3.3 discusses the planned approach for a bounding fire risk evaluation for STI changes in accordance with the guidance of NEI 04-10 (Revision 2).

| ENTCORPSO-GGNS-01, Rev. 0 GGNS PRA Technical Adequacy Page 9 of 17 3.2. GGNS Internal Events and Internal Flooding PRA Model 3.2.1. Plant Changes Not Yet Incorporated As discussed in in Section 3.1, an MCR database tracks PRA issues or improvements identified by PRA personnel. The MCR database includes the identification of plant changes that could impact the PRA model.
| |
| As part of the PRA evaluation for each STI change request, sensitivity cases are expected to be explored for areas of uncertainty associated with unresolved items (peer review Findings for ASME/ANS PRA Standard Capability II or plant changes) that would impact the results of the STI change evaluation, prior to presenting the results of the risk analysis to the IDP.
| |
| A review of the MCR database for GGNS identified several plant engineering changes (ECs) not yet implemented which may potentially impact the PRA. These are listed in Table 1, along with the corresponding EC and MCR numbers, as well as the potential impact on the PRA model.
| |

Summary of Plant Changes Not Yet Incorporated in the GGNS PRA Several child ECs were written to address NRC Information Notice 92-18 which describes a condition that results from post fire cable damage affecting an MOV control circuit causing both spurious valve actuation and loss of the torque/limit switch protection potentially causing mechanical failure of the valve.

| |
| The GGNS PRA model has undergone several peer reviews which document the motjel quality and identify any areas with potential for improvement. The following assessments have been performed and documented for the GGNS model:
| |
| * A peer review certification (Reference 8) of the GGNS PRA model Revision 1 was conducted by the Boiling Water Reactor Owners Group (BWROG) in October 1997 (Reference 9). The peer review concluded that the GGNS PRA was sufficient to support meaningful rankings for the assessment of SSCs and judged capable of supporting absolute risk determination to support applications.
| |
| * A full-scope industry peer review of the GGNS PRA model Revision 4 (Reference 10) was conducted by the BWROG September 21-25, 2015 (Reference 11 ). This peer review documented sixty-six (66) new F&Os including thirty-nine (39) Findings, twenty-six (26) Suggestions, and one (1) Best Practice. The peer review concluded that the GGNS PRA substantially (approximately 85% of the Supporting Requirements) met the ASME/ANS PRA standard at Capability Category II or better. This model revision was not issued for use because the PRA model was updated to Revision 4a to resolve the F&Os.
| |
| The GGNS PRA internal events model Revision 4a was approved in October 2017 (Reference
| |
| : 6) and incorporated changes, as applicable, to support the resolutions of the 2015 peer review findings. The 2015 peer review findings and the associated resolutions are documented in the MCR database and a resolution summary report (Reference 12). The full-scope peer review findings from 2015 were closed by an independent assessment conducted August 23-31, 2017.
| |
| The closure assessment was conducted in accordance with Appendix X to NEI 05-04 (Reference 13) utilizing the conditions of acceptance stated in an N~C letter to the Nuclear Energy Institute dated May 3, 2017 (Reference 14 ). The independent assessment is documented in the closure report (Reference 15) and concluded that none of the changes made to the GGNS PRA were considered a PRA upgrade or use of a new PRA method.
| |
| 3.2.3. Consistency with Applicable PRA Standards The GGNS PRA model Revision 4a meets the ASME/ANS PRA standard (Reference 4)
| |
| Capability Category II of the Supporting Requirements (SRs). Current Entergy PRA documentation includes a self-assessment that documents how each high-level requirement (HLR) and SR are met.
| |
| The latest full-scope peer review for GGNS was conducted in September 2015 (Reference 11) using the ASME/ANS PRA standard (Reference 4 ). Since then, model Revision 4a (Reference 6), to address the peer review findings and incorporate some elements of FLEX, was completed which ensured all the F&Os from the peer review were addressed. All the F&Os are captured and documented in the MCR database and the resolution summary report (Reference 12). No finding level F&Os remain open for the GGNS internal events and internal flooding PRA.
| |
| 3.3. GGNS Fire PRA Model Grand Gulf Nuclear does not currently have a fire PRA model. Therefore, a bounding fire risk evaluation, based on information from the Individual Plant Examination of External Events
| |
| | |
| ENTCORP50-GGNS-01, Rev. 0 GGNS PRA Technical Adequacy .
| |
| Page 15 of 17 (IPEEE, Reference 16) and other available insights for fire risk, will be performed for STI changes in accordance with the guidance of NEI 04-10 (Revision 2).
| |
| 3.4. Identification of Key Assumptions The Initiative 5b is a risk-informed process which uses PRA model results to support a proposed STI change. The IDP uses the PRA results as an input to decide whether an STI change is warranted. The methodology recognizes that a key area of uncertainty for this application is the standby failure rate utilized in the determination of the STI extension impact. Therefore, the methodology requires the performance of selected sensitivity studies on the standby failure rate of the component(s) of interest for the STI assessment.
| |
| Any additional sensitivity studies identified for specific STI changes are also required per NEI 04-10, Revision 1 (Reference 2). Therefore, results of the standby failure rate sensitivity study plus the results of any additional sensitivity studies identified during the performance of the reviews of gaps and open items as summarized in Sections 3.2 and 3.3 herein, will be documented and included in the results of the risk analysis submitted to the IDP.
| |
| 3.5. External Events and Shutdown Considerations The NEI 04-10 (Reference 2) methodology allows for STI change evaluations to be performed in the absence of quantifiable PRA models for all external hazards and shutdown. For those cases where the STI cannot be modeled in the plant PRA, or where a particular PRA model does not exist for a given hazard group, a ql:lalitative or bounding analysis is performed to provide justification for the acceptability of the proposed test interval change.
| |
| External hazards were evaluated in the GGNS IPEEE submittal (Reference 16) in response to the NRC IPEEE Program (Reference 17). The IPEEE Program was a one-time review of external hazard risk and was limited in its purpose to the identification of potential plant vulnerabilities and the understanding of associated severe accident risks. GGNS does not have a PRA model or applications associated with external hazards such as seismic, high wind or external flooding, and quantitative results cannot be provided to support this STI *effort.
| |
| Therefore, a qualitative or bounding approach will be used to assess external event hazard risk at GGNS for STI changes.
| |
| Because GGNS does not have external hazards or RG 1.200 conforming shutdown PRA models, external hazards and shutdown screening evaluations are performed for STI changes in accordance with the guidance of NEI 04-10, Revision 1 (Reference 2).
| |
| The GGNS shutdown safety program developed to support implementation of NUMARC 91-06 (Reference 18) is used for the shutdown risk evaluation, or an application-specific shutdown analysis may be performed for STI changes in accordance with the guidance of NEI 04-10, Revision 1 (Reference 2).

| |
| : b. Provisions for ensuring the plant is maintained in a safe condition if a loss of function condition exists;
| |
| : c. Provisions to ensure that an inoperable supported system's Completion Time is not inappropriately extended as a result of multiple support system inoperabilities; and
| |
| : d. Other appropriate limitations and remedial or compensatory actions.
| |
| A loss of safety function exists when, assuming no concurrent single failure, a safety function assumed in the accident analysis cannot be performed. For the purpose of this program, a loss of safety function may exist when a support system is inoperable, and:
| |
| : a. A required system redundant to system(s) supported by the inoperable support system is also inoperable; or
| |
| : b. A required system redundant to system(s) in turn supported by the inoperable supported system is also inoperable; or
| |
| : c. A required system redundant to support system(s) for the supported systems (a) and (b) above is also inoperable.

This Surveillance is modified by a Note identifying that the Surveillance is not required to be performed when THERMAL POWER is less than or equal to the actual LPSP of the RPC since the notch insertions may not be compatible with the requirements of BPWS (LCO 3.1.6) and the RPC (LCO 3.3.2.1). This Note also provides a time allowance such that the Surveillance is not required to be performed until the next scheduled control rod testing for control rods of the same class (i.e., fully withdrawn or partially withdrawn).

If more than 7.5% of the sample is declared to be "slow" per the criteria in Table 3.1.4-1, additional control rods are tested until this 7.5% criterion (e.g., 7.5% of the entire sample size) is satisfied, or until the total number of "slow" control rods (throughout the core, from all surveillances) exceeds the LCO limit. For planned testing, the control rods selected for the sample should be different for each test. Data from inadvertent scrams should be used whenever possible to avoid unnecessary testing at power, even if the control rods with data were previously tested in a sample.

| |
| SR 3 .1. 4. 3 When work that could affect the scram insertion time is performed on a control rod or the CRD System, testing must be done to demonstrate that each affected control rod retains adequate scram performance over the range of applicable reactor pressures from zero to the maximum permissible pressure. The scram testing must be performed once before declaring the control rod OPERABLE. The required scram time testing must demonstrate that the arfected control rod is still within acceptable limits.
| |
| The limits for reactor pressures< 950 psig are established based on a high probability of meeting the acceptance criteria at reactor pressures z 950 psig. Limits for z 950 psig are found in Table 3.1.4-1. If testing demonstrates the affected control rod does not meet these limits, but is within the 7 second limit of Table 3.1.4-1 Note 2, the control rod can be declared OPERABLE and "slow."

This minimum pump flow rate requirement ensures that, when combined with the sodium pentaborate solution concentration requirements, the rate of negative reactivity insertion from the SLC System will adequately compensate for the positive reactivity effects encountered during power reduction, cooldown of the moderator, and xenon decay.

| RPS Instrumentation B 3.3.1.1 BASES SURVEILLANCE SR 3.3.1.1.1 and SR 3.3.1.1.19 REQUIREMENTS (continued) Performance of the CHANNEL CHECK ensures that a gross failure of instrumentation has not occurred. A CHANNEL CHECK is normally a comparison of the parameter indicated on one channel to a similar parameter on other channels. It is based on the assumption that instrument channels monitoring\
| |
| the 1 same parameter should read approximately the same value.
| |
| Significant deviations between the instrument channels could be an indication of excessive instrument drift on one of the channels or something even more serious. A CHANNEL CHECK will detect gross channel failure; thus, it.is key to verifying the instrumentation continues to operate properly between each CHANNEL CALIBRATION.-
| |
| Agreement criteria are determined by the plant staff based on a combination of the channel instrument uncertainties, including indication and readability. If a channel is outside the criteria, it may be an indication that the instrument has drifted outside its limit.
| |
| The agreement criteria include an expectation of overlap when transitioning between neutron flux instrumentation.
| |
| The overlap between SRMs and IRMs must be demonstrated 'prior to withdrawing SRMs from the fully inserted position since indication is being transitioned from SRMs to the IRMs.
| |
| This will ensure that reactor power will not be increased into a neutron flux region without adequate indication. The overlap between IRMs and APRMs is of concern when reducing power into the IRM range. On power increases, the system design will prevent further increases (by initiating a rod block) if adequate overlap is not maintained.
| |
| Overlap between IRMs and APRMs exists when sufficient IRMs and APRMs concurrently have on-scale readings such that the transition between MODE 1 and MODE 2 can be made without either APRM downscale rod block, or IRM upscale rod block.
| |
| Overlap between SRMs,and IRMs similarly exists when, prior to withdrawing the SRMs from 'the fully inserted position, IRMs are above 2 I 4 0 on range 1 before SRMs have r'eached the upsc~le rod block.
| |
| * If o~erlap for a group of channels is not demon~trated (e.g., IRM/APRM overlap), the reason for the failure of the Survei~lance should be determined and the appropriate channel(s) that are required in the current MODE or condition should be declared inoperable.

| SR 3-.3.1.1.10 for the designated function is modified by two notes identified in Table 3.3.1.1-1. The first note requires evaluation of channel performance for the condition where the as-found setting for the.channel setpoint is outside its as-found tolerance but conservative with respect to the Allowable Value. Evaluating channel performance will verify that the channel will continue to behave in accordance with safety analysis assumptions and the channel performance assumptions in the setpoint methodology. The purpose of the assessment is to ensure confidence in channel performance prior to returning the channel to service. Performance of these channels will be evaluated under the Corrective Action Program. Entry into the Corrective Action Program ensures required review and documentation of the condition to establish a reasonable expectation for continued OPERABILITY.
| |
| The second note requires that the as-left setting for the channel be within the as-left tolerance of the Nominal Trip Setpoint (NTSP). Where a setpoint more conservative than the NTSP issued in the plant surveillance procedures, the as-left and as-found tolerances, as applicable, will be applied to the surveillance procedure setpoint. This will ensure that sufficient margin to the Safety Limit and/or Analytical Limit is maintained. If the as-left channel s~tting cannot be returned to a setting within the as-left tolerance of the NSP, then the channel shall be declared inoperable.

| -t-- ( continued) This Surveillance consists of a verification of the SRM instrument readout to ensure that the SRM reading is greater than a specified minimum-count rate. This ensures that 'the detectors are indicating count rates indicative of neutron flux levels within the core. Verification of the signal to noise ratio also ensures that the detectors are 'inserted to a normal operating level. In a fully withdrawn condition, the detectors are sufficiently removed from the fueled region of the core to essentially eliminate neutrons from reaching the detector. Any count rate obtained while fully withdrawn is assumed to be "noise" only. With few fuel assemblies loaded, the SRMs will not have a high enough count rate to satisfy the SR. rherefore, allowances are made for loading sufficient "source" ~aterial, in the form of irradiated fuel assemblies, to establish the minimum count rate.
| |
| To accomplish this, the SR is modified by a Note that states that the count rate is 1 not required to be met on an SRM that has less than or equal to four fuel assemblies adjacent to the SRM and no other fuel assemblies are in the associated core quadrant.* With four,or less fuel assemblies loaded around each SRM and no other fuel assemblies in the associated quadrant, even wtth a control rod withdrawn the The Surveillance configuration will not be critical.

| SURVEILLANCE The Surveillances are modified by a Note to indicate that REQUIREMENTS when a channel is placed in an inoperable status solely for performance of required Surveillances, entry into associated Conditions and Required Actions may be delayed for up to 6 hours provided the associated Function maintains ATWS-RPT trip capability. Upon completion of the Surveillance, or expiration of the 6 hour allowance, the channel must be returned to OPERABLE status or the applicable Condition entered and Required Actions taken. This Note is based on the reliability analysis (Ref. 2) assumption of the average time required to perform channel surveillance.

The purpose of the assessment is to ensure confidence in the channel performance prior to returning the channel to service. For channels determined to be OPERABLE but degraded, after returning the channel to service the performance of these channels will be evaluated under the plant Corrective Action Program.- Entry,into the Corrective Action Program will ensure required review and documentation of the condition.

| Jet Pumps B 3.4.3 BASES (continued)
| |
| SURVEILLANCE SR 3.4.3.1 REQUIREMENTS This SR is designed to detect significant degradation in jet pump performance that precedes jet pump failure (Ref. 2). This SR is required to be performed only when the loop has forced recirculation flow since surveillance checks and measurements can only be performed during jet pump operation. The jet pump failure of concern is a complete mixer displacement due to jet pump beam failure. Jet pump plugging is also of concern since it adds flow resistance to the recirculation loop. Significant degradation is indicated. if the specified criteria confirm unacceptable
| |
| *deviations from established patterns or relationships. The allowable deviations from the established patterns have been developed based on the variations experienced at plants during normal operation and with jet pump assembly failures (Refs. 2 and 3). Since refueling activities (fuel assembly replacement or shuffle, as well as any modifications to fuel support orifice size or core plate bypass flow) can affect the relationship between core flow, jet pump flow, and recirculation loop flow, these relationships may need to be re-established each cycle. Similarly, initial entry into extended single recirculation loop operation may also require establishment of these relationships. During the initial weeks of operation under such conditions, wh511 - - - ining new "established patterns,"
| |
| engineering judgment oft e fflffl'J' urveillance results is used to detect significant abnormalities w
| |
| * Id indicate a jet pump failure.
| |
| The recirculation flow control valve (FCV) operating characteristics (loop flow versus FCV position) are determined by the flow resistance from the loop suction through the jet pump nozzles. A change in the relationship indicates a flow restriction; loss in pump hydraulic performance, leak, or new flow path between the recirculation pump discharge and jet pump nozzle. For this criterion, the loop flow versus FCV position relationship must be verified.
| |
| Total core flow can be determined from measurements of the recirculation loop drive flows. Once this relationship has been established, increased or reduced tota(core flow for the same recirculation loop drive flow may be an indication of failures in one or several jet pumps.

| In MODES 4 and 5, the RHR System may operate in the shutdown cooling mode, or be aligned to allow alternate means to remove decay heat and sensible heat from the reactor. Therefore, RHR valves ithat are required for LPCI subsystem operation may be aligned for decay heat removal.
| |
| One LPCI subsystem of the RHR System may be considered OPERABLE for the ECCS function if all the required valves in the LPCI flow path can be manually realigned (remote or local) to allow injection into the RPV and the system is not otherwise inoperable. This will ensure adequate core cooling if an inadvertent vessel draindown should occur.

This SR does not apply to susceptible to gas valves that are locked, sealed, or otherwise secured in position since accumulation. these were verified to be in the correct position prior to locking, sealing, or securing. A valve that receives an initiation signal is allowed to be in a nonaccident position provided the valve will automatically reposition in the proper stroke time. This SR does not require any testing or valve manipulation; rather, it involves verification that those valves capable of potentially being mispositioned are in the correct position. This SR does not apply to valves that cannot be inadvertently misaligned, such as The Surveillance check valves.

| |
| The flow tests for the RCIC System are performed at two different pressure ranges such that system capability to provide rated flow is tested both at the higher and lower operating ranges of the system.
| |
| Additionally, adequate steam flow must be passing through the main turbine or turbine bypass valves to continue to control reactor pressure when the RCIC System diverts steam flow. Since the required reactor steam pressure must be available to perform SR 3.5.3.3 and SR 3.5.3.4, sufficient time is allowed after adequate pressure and flow are achieved to perform these SRs. Reactor startup is allowed prior to performing the low pressure Surveillance because the reactor pressure is low and the time to satisfactorily perform the Surveillance is short. The reactor pressure is allowed to be increased to normal operating pressure since it is assumed that the low pressure test has been satisfactorily completed and there is no indication or reason to believe that RCIC is inoperable:

| |
| SURVEILLANCE SR 3.6.1.2.1 \.1 REQUIREMENTS Maintaining primary containment air locks OPERABLE requires compliance with the leakage rate test requirements of 10 CFR 50, Appendix J (Ref. 2), as modified by approved exemptions. This SR reflects the leakage rate testing requirements with regard to air lock leakage (Type B leakage tests). The leakage rate testing requirements include the airlock test connection valves (Type C leakage tests). The periodic testing requirements verify that the air lock leakage does not exceed the allowed fraction of the overall primary containment leakage rate.
| |
| The SR has been modified by two Notes. Note 1 states that an inoperable air lock door does not invalidate the previous successful performance of the overall air lock leakage test.
| |
| This is considered reasonable since either air lock door is capable of providing a fission product barrier in the event of a DBA. Note 2 has been added to this SR, requiring the results to be evaluated against the acceptance criteria of SR 3.6.1.1.1. This ensures that air lock leakage is properly accounted for in determining the overall primary containment leakage rate. Since the overall primary containment leakage rate is only applicable in MODES 1, 2, and 3 operation, the Note 2 requirement is imposed only during these MODES.

| Two Notes are added to this SR. The first Note applies to valves and blind flanges located in high radiation areas and allows them to be verified by use of administrative controls. Allowing verification by administrative controls is considered acceptable, since access to these areas is typically restricted during MODES 1, 2, and 3 for ALARA reasons. Therefore, the probability of misalignment of these devices, once they have been verified to be in the proper position, is low. A second Note is included to clarify that PCIVs open under administrative controls are not required to meet the SR during the time the PCIVs are open. This SR does not apply to valves that are locked, sealed, or otherwise secured in the closed position, since these were verified to be in the correct position upon locking, sealing, or securing.

| SR 3.6.2.3.2 RHR Suppression Pool Cooling System piping and components have the potential to develop voids and pockets of entrained gases. Preventing and managing gas intrusion and accumulation is necessary for proper operation of the RHR suppression pool cooling subsystems and may also prevent water hammer and pump cavitation.
| |
| Selection of RHR Suppression Pool Cooling System locations susceptible to gas accumulation is based on a review of system design information, including piping and instrumentation drawings; isometric drawings, plan and elevation drawings, and calculations. The design review is supplemented by system walk downs to validate the system high points and to confirm the location and orientation of important components that can become sources of gas or could otherwise cause gas to be trapped or difficult to remove during system maintenance or restoration.
| |
| Susceptible locations depend on plant and system configuration, such as stand-by versus operating conditions.

| The RHR Suppression Pool Cooling System is OPERABLE when it is sufficiently filled with water. Acceptance criteria are established for the volume of accumulated gas at susceptible locations. If accumulated gas GRAND GULF B 3.6-59 LBDGR 14044 Page 115 of 197

If it is determined by subsequent evaluation that the RHR Suppression Pool Cooling System is not rendered inoperable by the accumulated gas (i.e., the system is sufficiently filled with water), the Surveillance may be declared met.
| |
| Accumulated gas should be eliminated or brought within the acceptance criteria limits.
| |
| RHR Suppression Pool Cooling System locations susceptible to gas accumulation are monitored and, if gas is found, the gas volume is compared to the acceptance criteria for the location. Susceptible locations in the same system flow path which are subject to the same gas intrusion mechanisms may be verified by monitoring a representative subset of susceptible locations. Monitoring may not be practical for locations that are inaccessible due to radiological or environmental conditions, the plant configuration, or personnel safety. For these locations alternative methods (e.g., operating parameters, remote monitoring) may be used to monitor the susceptible location. Monitoring is not required for susceptible locations where the maximum potential accumulated gas void volume has been evaluated and determined to not challenge system OPERABILITY.

Allowing verification by administrative controls is considered acceptable, since access to these areas is typically restricted during MODES 1, 2, and 3 for ALARA reasons.
| |
| Therefore, the probability of misalignment of these SCIVs, once they have been verified to be in the proper position, is low.

Generally, SCIVs must close within 120 seconds to support the functioning of the Standby Gas Treatment System.

| LCO The specified water level preserves the assumption of the fuel handling accident analysis (Ref. 2. As such, it is the minimum required for fuel ~

| movement within the spent fuel storage pool and upper containment fuel storage pool.
| |
| APPLICABILITY This LCO applies whenever movement of irradiated fuel assemblies occurs in the associated fuel storage racks since .the potential for a release of fission products exists.
| |
| ACTIONS Required Action A.1 is modified by a Note indicating that LCO 3.0.3 does not apply. If moving irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations. Therefore, inability to suspend movement of irradiated fuel assemblies is not a sufficient reason to require a reactor shutdown.
| |
| When the initial conditions for an accident cannot be met, steps should be taken to preclude the accident from occurring. With either fuel pool level less than required, the movement of irradiated fuel assemblies in the associated storage pool is suspended immediately. Suspension of this activity shall not preclude completion of movement of an irradiated fuel assembly to a safe position. This effectively precludes a spent fuel handling accident from occurring.

| |
| To minimize the wear on moving parts that do not get lubricated when the engine is not running, these SRs have been modified by Notes (the Note for SR 3.8.1.21 and Note 2 for SR 3.8.1.2) to indicate that all DG starts for these Surveillances may be preceded by an engine prelube period and
| |
| +
| |
| followed by a warmup period prior to loading.
| |
| For the purposes of this testing, the DGs are started from standby conditions. Standby conditions for a DG mean that the diesel engine coolant and oil are being continuously circulated and temperature is being maintained consistent with manufacturer recommendations for DG 11 and DG 12. For DG 13, standby conditions mean that the lube oil is heated by the jacket water and continuously circulated through a portion of the system as recommended by the vendor. Engine jacket water is heated by an immersion heater and circulates through the -system by natural 1
| |
| circulation.
| |
| In order to reduce stress and wear on diesel engines, the manufacturer recommends that the DGs be gradually accelerated to synchronous speed prior to loading. These modified start procedures are the intent of Note 3 of SR 3.8.1.2, which is only applicable when such procedures are used.

| REQUIREMENTS (continued)
| |
| , SR 3.8.1.21 requires that, at a~184 elay frequenoy, the DG starts from standby conditions and achieves required voltage and frequency within 10 seconds. The DG's ability to maintain the required voltage and frequency is tested by those SRs which require DG loading. The 10 second start requirement supports the assumptions in the design basis LOCA analysis (Ref. 5). The start requirements may not be applicable to 3.8.1.2 (see Note 3 of SR 3.8.1.2), when a modified start procedure as described above is used. If a modified start is not used, the start requirements of SR 3.8.1.21 apply. Since SR 3.8.1.21 does require a 10 second start for each DG, it is more restrictive than SR 3.8.1.2, and it may be performed in lieu of SR 3.8.1.2.* This is the intent of Note 1 of SR 3.8.1.2. Similarly, the performance of SR 3.8.1.12 or SR 3.8.12.19 also satisfies the requirements of SR 3.8.1.2 and SR 3.8.1.21. In addition to 1' the SR requirements, the time for the DG to reach steady state operation is periodically monitored (data is taken once per 6 months during the performance of SR 3.8.1.21) an.d the trend evaluated to identify degradation of governor and voltage regulator performance.

| SR 3.8.1.14 Regulatory Guide 1.9 (Ref. 3) requires demonstration onee per 24 months 'i-that the DGs can start and run continuously at full load capability for an interval of not less than 24 hours - 22 hours of which is at a load equivalent to the continuous rating of the DG, and 2 hours of which is at a load equivalent to 110% of the continuous duty rating of the qG. An exception to the loading requirements is made for DG 11 and DG 12. DG 11 and DG 12 are operated for 24 hours .at a load greater than or equal to the maximum expected post accident load. Load carrying capability testing of the Transamerica Delaval Inc. (TOI) diesel generators (DG 11 and DG 12) has been limited to a load less than that which corresponds to 185 psig brake mean effective pressure (BMEP). Therefore, full load testing is performed at a load~ 5450 kW but< 5740 kW (Ref. 15). The DG starts for this Surveillance can be performed either from standby or hot conditions. The provisions for prelube and warmup, discussed in SR 3.8.1.2, and for gradual loading, discussed in SR 3.8.1.3, are applicable to this SR.
| |
| In order to ensure that the DG is tested under load conditions that are as close to design conditions as possible, testing must be performed using a power factor (continued)

| This SR has been modified by two Notes. Note 1 ensures that the test is performed with the diesel sufficiently hot. The requirement that the diesel has operated for at least 1 hour at full load conditions or until operating temperatures stabilized prior to performance of this Surveillance is based on manufacturer recommendations for achieving hot, conditions. The DG 11 and 12 load band is provided to avoid routine overloading of the TOI pG. Routine overloads may* result in more frequent teardown inspections in accordance with vendor recommendations in order to maintain DG OPERABILITY. Momentary transients due to changing bus loads do not invalidate this test. Note 2 allows all DG starts to be preceded by an engine prelube period to minimize wear and tear on the diesel during testing.
| |
| SR 3.8.1.16 As required by Regulatory Guide 1.9 (Ref. 3) this Surveillance ensures that the manual synchronization and load transfer from the DG to each required offsite source can be made and that the DG can be returned to ready-to-load status when offsite power is restored. It also ensures that the undervoltage logic is reset to allow the DG to reload if a subsequent loss of offsite power occurs. The DG is considered to be in ready-to-load status when the DG is at rated speed and voltage, the output breaker is.

The sequencing logic controls the permissive and starting signals to motor breakers to prevent overloading of the bus power supplies due to high motor starting currents. The 10% load sequence time interval tolerance ensures that sufficient time exist)s for the bus power supplies to restore frequency and voltage prior to applying the next load and that safety analysis assumptions regarding ESF equipment time delays are not violated. Reference 2 provides a summary of the automatic loading of ESF buses.

| |
| This SR is modified by two Notes. Note 1 allows the once per 60 months performance of SR 3.8.4.8 in lieu of SR 3.8.4.7. This substitution is acceptable because SR 3.8.4.8 represents a more severe test of battery capacity than SR 3.8.4.7. The reason for Note 2 is that performing the Surveillance would remove a required DC electrical power subsystem from service, perturb the electrical distribution system, and challenge safety systems. The Division 3 test may be performed in MODE 1, 2, or 3 in conjunction with HPCS system outages. Credit may be taken for unplanned events that satisfy the Surveillance.
| |
| SR 3.8.4.8 A battery performance test is a test of constant current capacity of a battery, normally done in the as found condition, after having been in service, to detect any change in the capacity determined by the acceptance test: The test is intended to determine overall battery degradation due to age and usage.
| |
| The acceptance criteria for this Surveillance is consistent with IEEE-450 (Ref: 9) and IEEE-485 (Ref. 12). These references recommend that the 'f...
| |
| battery be replaced if its capacity is below 80% of the manufacturer's rating. A capacity of 80% shows that the battery rate of deterioration is increasing, even if there is ample capacity to meet the load requirements.

| Continued operation is only permitted for 31 days before battery cell parameters must be restored to within Category A and B limits. Taking into consideration that while battery capacity is degraded, sufficient capacity exists to perform the intended function and to allow time to fully restore the battery cell parameters to normal limits, this time is acceptable for operation prior to declaring the DC batteries inoperable.
| |
| * When any battery parameter is outside the Category C limit for any connected cell, sufficient capaciW to supply the maximum expected load requirement is not assured and the corresponding DC electrical power subsystem must be declared inoperable. Additionally, other potentially extreme conditions, such as not completing the Required Actions of Condition A within the -required Completion Time or average electrolyte temperature of representative cells falling below 60°F, also are cause for immediately declaring the associated DC electrical power subsystem inoperable.

| * With the Division 3 electrical power distribution system inoperable, the rnvision 3 powered systems are not capable of performing their intended functions. Immediately declaring the high pressure core spray inoperable allows the ACTIONS of LCO 3.5.1, "ECCS - Operating," to apply appropriate limitations on continued reactor operation.
| |
| Condition E corresponds to a level of degradation in the electrical distribution system that causes a required safety function to be lost.
| |
| When more than one Condition is entered, and this results in the loss of a required function, the plant is in a condition outside the accident analysis.
| |
| Therefore, no additional time is justified for continued operation. LCO 3.0.3 must be entered immediately to commence a controlled shutdown.
| |
| SURVEILLANCE SR 3.8.7.1 REQUIREMENTS Meeting this Surveillance verifies that the AC and DC electrical power distribution systems are functioning properly, with the correct circuit breaker alignment. The correct breaker alignment ensures the appropriate separation and independence of the electrical divisions is maintained, and the appropriate voltage is available to each required bus.

| |
| This may be performed as an administrative check, by examining logs or other information, to determine whether the components ar~ out of service for maintenance or other reasons. It is not necessary to perform the Surveillances needed to demonstrate the OPERABILITY of the components.
| |
| If, however, any required component is inoperable, then it must be restored to OPERABLE status. In this case, a surveillance may need to be performed to restore the component to OPERABLE status. Actions must continue until all required components are OPERABLE.
| |
| C. l and C. 2 If no decay heat removal subsystem (RHR shutdown cooling subsystem or ADHRS) is in operation, an alternate method of coolant circulation is required to be established within 1 hour. The Completion Time is modified such that 1 hour is applicable separately for each occurrence involving a loss of.-coolant circulation.
| |
| During the period when the reactor coolant is being circulated by an alternate method (other than by the required RHR shutdown cooling subsystem or ADHRS), the reactor coolant temperature must be periodically monitored tp ensure proper functioning of the alternate method. The once per hour Completion Time is deemed appropriate.

| Program.
| |
| SR 3.9.9.2 RHR Shutdown Cooling System piping and components have the potential to develop voids and pockets of entrained gases. Preventing and managing gas intrusion and accumulation is necessary for proper operation of the RHR shutdown cooling subsystems and may also prevent water hammer, pump cavitation, and pumping of noncondensible gas into the reactor vessel.
| |
| Selection of RHR Shutdown Cooling System locations susceptible to gas accumulation is based on a review of system design information, including piping and instrumentation drawings, isometric drawings, plan and elevation drawings, and calculations. The design review is supplemented by system walk downs to validate the system high points and to confirm the location and orientation of important components that can become sources of gas or could otherwise cause gas to be trapped or difficult to remove during system maintenance or restoration.
| |
| Susceptible locations depend on plant and system configuration, such as stand-by versus operating conditions.
| |
| The RHR Shutdown Cooling System is OPERABLE when it is sufficiently filled with water. Acceptance criteria are established for the volume of accumulated gas at susceptible locations. If accumulated gas is discovered that exceeds the acceptance criteria for the susceptible location (or the volume of accumulated gas at one or more susceptible locations exceeds an acceptance criteria for gas volume at the suction or discharge of a pump), the Surveillance is not met. If it is determined by subsequent evaluation that the RHR Shutdown Cooling System is not rendered inoperable by the accumulated gas (i.e., the system is sufficiently filled with water), the Surveillance may be declared met.
| |
| Accumulated gas should be eliminated or brought within the acceptance criteria limits.

| BASES ( continued)
| |
| ACTIONS A.1, A.2, A.3.1, and A.3.2 These Required Actions are provided to restore compliance with the Technical Specifications overridden by this Special Operations LCO. Resrtoring compliance will also result in 1
| |
| exiting the Applicab ili ty of this Special Operations LCO.
| |
| All CORE ALTERATIONS except control rod insertion, if~in progress, are immediately suspended in accordance with Required Action A.1, and all insertable control rods in core cells that contain one or more fuel assemblies are fully inserted within 1 hour, in accordance with Required Action A.2. This will preclude potential mechanisms that could lead to criticality. Suspension of CORE ALTERATIONS shall not preclude the completion of movement of a component to a safe condition. Placing the reactor mode switch in the shutdown position will ensure that all inserted control rods, remain inserted and result in operation in accordance with Table 1.1-1. Alternatively, if in MODE 5, the reactor mode switch may be placed in the refuel position, which will also result in operating in accordance with Table 1.1-1. A Note is added to Required Action A.3.2 to indicate that this Required Action is not applicable in MODES 3 and 4, since only the shutdown position is allowed in these MODES. The allowed Completion Time of 1 hour for Required Actions A.2, A.3.1, and A.3.2 provides sufficient time to normally insert the control rods and place the reactor mode switch in the required position, based on operating experience, and is acceptable given that all operations that could increase core* reactivity have been suspended.
| |
| SURVEILLANCE SR 3.10.2.1 and SR 3.10.2.2 REQUIREMENTS Meeting the requirements of this Special Operations LCO maintains operation consistent with or conservative to operating with the reactor mode switch in the shutdown position (or the refuel position for MODE 5). The functions of the reactor mode switch interlocks that are not in effect, due to the testing in progress, are adequately compensated for by the Special Operations LCO requirements.
| |
| The administrative controls are to be periodically verified to ensure that the operational requirements continue to be met. To provide additional assurance that control rods are not withdrawn, SR 3.10.2.1 is performed by two licensed operators or other.technically qualified members* of the unit technical staff.

| : 1. Does the proposed change involve a significantincrease in the probability or
| |
| * consequences of any accident previously evaluated?
| |
| Response: No.
| |
| The proposed change relocates the specified frequencies for periodic surveillance requirements to licensee control under a new Surveillance Frequency Control Program.
| |
| Surveillance frequencies are not an initiator to any ac*cident previously evaluated. As a result, the probability of any accident previously evaluated is not significantly increased.
| |
| The systems and components required by the technical specifications for which the surveillance frequencies are relocated are still required to be operable, meet the acceptance criteria for the surveillance requirements, and be capable of performing any mitigation function assumed in the accident analysis. As .a result, the consequences of any accident previously evaluated are not significantly increased.
| |
| Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated. *
| |
| : 2. Does the proposed change create the possibility of a new or different kind of accident from any previously evaluated?
| |
| Response: No.
| |
| No new or different accidents result from utilizing the proposed change. The changes do not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a change in the methods governing normal pl~nt operatio*n. In addition, the changes do not impose any new or different requirements. The changes do not alter assumptions made in the safety analysis. The proposed changes are consistent with the safety analysis assumptions and current plant operating practice.

| |
| -Proposed No Significant Hazards Consideration GNR0-2018/00013 Therefore, the proposed changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.
| |
| : 3. Does the proposed change involve a significant reduction in the margin of safety?
| |
| F3esponse: No.
| |
| The design, operation, testing methods, and acceptance criteria for systems, structures, and components (SSCs ), specified in applicable codes and standards (or alt$rnatives approved for use by the NRC) will continue to be met as described in the plant licensing basis (including*the t'inal safety analysis report and bases to TS), since these are not affected by changes to the surveillance frequencies. Similarly, there is no impact to safety analysis acceptance criteria as described in the plant licensing basis. To evaluate a change in the relocated *surveillance frequency, Entergy will perform a probabilistic risk evaluation using the guidance contained in NRC approved NEI 04-10, Rev. 1 in accordance with the TS SFCP. NEI 04-10, Rev. 1, methodology provides reasonable acceptance guidelines and methods for evaluating the risk increase of proposed changes to surveillance frequencies consistent with Regulatory Guide 1.177.
| |
| Therefore, the proposed changes do not involve a significant reduction in a margin of safety.
| |
| Based upon the reasoning presented above, licensee concludes that the requested change does not involve a significant hazards consideration as set forth in 10 CFR 50.92(c),
