Farley Nuclear Plant Response to Request for Additional Information Regarding License Amendment Request for Transition to 10 CFR 50.48(c) - NFPA 805 Performance Based Standard for Fire Protection for Light Water Reactor Generating Plants Ladies and Gentlemen:

By letter dated September 25, 2012, the Southern Nuclear Operating Company (SNC) submitted a license amendment request (LAR) for Joseph M. Farley Units 1 and 2 (Ref. TAC NOS. ME9741 and ME9742). The proposed amendment requests the review and approval for adoption of a new fire protection licensing basis which complies with the requirements in Sections 50.48(a) and 50.48(c) to Title 10 to the Code of Federal Regulations (10 CFR), and the guidance in Regulatory Guide (RG) 1.205, Revision 1, Risk-Informed, Performance-Based Fire Protection for Existing Light-Water Nuclear Power Plants.

By letter dated December 12, 2012, the Nuclear Regulatory Commission (NRC)

Staff requested supplemental information regarding the acceptance of the license amendment (Adams Accession No. ML12345A398). SNC provided the requested information by letter dated December 20, 2012. The NRC staff subsequently completed the acceptance review by letter dated January 24, 2013, (Adams Accession No. ML13022A158).

By letter dated July 8, 2013, the NRC Staff formally transmitted a request for additional information (RAI) related to the referenced license amendment. SNC's responses to these RAls are being provided by three submittals. By letter dated September 16, 2013, SNC provided the first set of responses. By letter dated October 30, 2013, SNC provided the second set of responses and by letter dated November 12, 2013, SNC provided the remaining set of responses.

By letter dated March 28, 2014, the NRC Staff formally transmitted the second round of requests for additional information related to the referenced license

U.S. Nuclear Regulatory Commission NL-14-1273 Page 2 amendment request. By letter dated April 23, 2014, SNC provided the 30 day response to the second round of RAIs. By letter dated May 23, 2014, SNC provided the 60 day response to six of the eight remaining RAIs.

By letter dated July 3, 2014, SNC provided revised Attachments S, V, and W.

The updated total plant, Fire PRA, and delta risk values were provided in the updated Attachments V and W. These attachments provided the response to PRA RAIs 06.a.01 and 35. The revised Attachment S reflected the updates associated with the RAI responses. Revisions to Table C-2 in Attachment C and Attachment G were to be provided in a separate submittal. Along with other revisions, a new modification item was added to Attachment S for installation of the Generation III Westinghouse shutdown seals for the reactor coolant pumps on both Unit 1 and Unit 2.

By letter dated July 11, 2014, the NRC staff transmitted additional RAIs related to the credit for the next generation of the Westinghouse Reactor Coolant Pump shutdown seals (PRA RAI 35.01) and the composite analysis of the probabilistic risk assessment (PRA RAI 36). By letter dated August 11, 2014, SNC provided the response to PRA RAIs 16.a.02 and 35.01. During a teleconference held on August 1, 2014, it was agreed that the response to PRA RAI 36 would be provided by August 29, 2014.

The enclosure to this letter provides the response to PRA RAI 36. The response contains a summary of changes as requested in the August 1, 2014 teleconference. Revisions to Table C-2 in Attachment C, NFPA 805 Required Fire Protection Systems and Features, are provided as an attachment. Based on the nature of the changes involved with previous RAI responses, there have been no significant changes to the current VFDR dispositions as identified in Table C-1 found in Attachment C. Also, no VFDRs have been added or deleted. As a result, it is not necessary to revise Table C-1. It should be noted that the A CDF and A LERF numbers and "Required Fire Protection Systems and Features" tables in Table C-1 will change as a result of the PRA model changes. However, this information is included in other attachments which are being revised. Therefore, the C-1 table will not be revised at this time.

Also, reviews have determined that there are no revisions to Attachment G that are necessary to account for recovery actions that are required for risk or defense in depth. Revisions to Attachment S, Modifications and Implementation Items, Attachment V, Fire PRA Quality, and Attachment W, Fire PRA Insights, are also provided. These revisions reflect the updates associated with the RAI responses and add back 4 implementation items to Attachment S that were inadvertently omitted in a previous revision. Attachments S and W contain sensitive information and should be withheld from public disclosure under 10 CFR 2.390.

The No Significant Hazards Consideration determination provided in the original submittal is not altered by the RAI responses provided herein.

This letter contains no new NRC commitments. If you have any questions, please contact Ken McElroy at (205) 992-7369.

Joseph M. Farley Nuclear Plant Response to Request for Additional Information Regarding License Amendment Request for Transition to 10 CFR 50.48(c)

NFPA 805 Performance Based Standard for Fire Protection for Light Water Reactor Generating Plants Response to Request for Additional Information Response to Request for Additional Information Farley RAI PRA 36 By letter dated September 25, 2012 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML12279A235), as supplemented by letter dated October 30, 2013 (ADAMS Accession No. ML13305A105),

Southern Nuclear Company (SNC) requested an amendment to the Technical Specifications for the Joseph M. Farley Nuclear Plant (Farley). Specifically, the requested change would allow the licensee to adopt National Fire Protection Association Standard 805, "Performance-Based Standard for Fire Protection for Light Water Reactor Generating Plants."

Section 2.4.3.3 of NFPA 805 states that the Probabilistic Risk Assessment approach, methods, and data shall be acceptable to the NRC. Section 2.4.4.1 of NFPA-805 further states that the change in public health risk arising from transition from the current fire protection program to an NFPA-805 based program, and all future plant changes to the program, shall be acceptable to the NRC. RG 1.174 provides quantitative guidelines on core damage frequency, large early release frequency, and identifies acceptable changes to these frequencies that result from proposed changes to the plant's licensing basis and describes a general framework to determine the acceptability of risk-informed changes. The U.S. Nuclear Regulatory Commission (NRC) staff has identified additional information that is required to fully characterize the risk estimates.

Provide the results of a composite analysis that shows the integrated impact on the fire risk (core damage frequency (CDF), larger early release frequency (LERF), change in (A)CDF, ALERF) after replacing all the identified methods and weaknesses. As the review process is concluded, additional changes to replace any method or weakness still under review may be required. In this composite analysis, for those cases where the individual issues have a synergistic impact on the results, a simultaneous analysis must be performed, specifically for those items listed below.

For cases where no synergy exists, a one-at-a-time analysis may be done. If the impact on the change in risk from transition is negligible, a quantitative evaluation is unnecessary.

a.

The results from the analysis for PRA RAI 35.01 above.

b.

In the LAR submittal dated September 12, 2012, and the LAR supplement dated December 20, 2012, sensitivities related to the electrical cabinet fire severity method (Section V.2.1) and use of control power transformer (CPT) (Section V.2.3; also response to PRA RAI 08.a).

E1-2 Response to Request for Additional Information

RESPONSE

The response below addresses each of the items specified in the RAI with respect to the manner in which these issues are addressed in the Fire PRA Model used to provide the quantification results that accompany this RAI transmittal. The disposition of the issues specified below have been applied in the Fire PRA model and the change in risk calculations.

a) PRA RAI 35.01 - The responses to PRA RAI 35.01 (Adams Accession No. ML14223A646) justifies the credit for the SDS in the Farley model. Based on available supporting documentation for the new SDS by Westinghouse, the current credit is judged to be bounding. As identified, Implementation item 32 has been added to Attachment S, Table S-3 to address the specific model change once the new seals are installed.

b) From NFPA 805 LAR submittal, the December 20, 2012 LAR Supplement and subsequent RAI responses:

i) NFPA 805 LAR Submittal Section V.2.1 - The electrical cabinet fire severity method is no longer used in the Farley Fire PRA.

ii) NFPA 805 LAR Submittal Section V.2.3 and the response to RAI PRA 08(a) - The hot short-induced spurious operation conditional likelihood estimates used in the development of the Fire PRA has been updated to reflect the guidance provided in ML14086A165, "Supplemental Interim Technical Guidance on Fire-Induced Circuit Failure Mode Likelihood Analysis". This guidance has been incorporated into the base model. The original response to RAI PRA 08(a) (ADAMS Accession No. ML13318A027) indicated that this issue would be addressed via a sensitivity analysis. This response supersedes the previous response.

c) From RAI Responses dated September 16, 2013:

i)

PRA RAI 01.a - Credit for VEWFDS has been eliminated from the control room main control board area (fire zone 0401). (See PRA RAI 01.a (Adams Accession No. ML14038A019) and subsequent PRA RAI 01.01 response) (Adams Accession No. ML14147A368).

ii) PRA RAI 15.a - The updated seismic contribution to the total plant risk, as specified in PRA RAI 15.a, is being used. (ADAMS Accession No. ML14038A019) iii) PRA RAI 28.k - The number of vertical sections of 1 F Switchgear in Room 0335 was corrected to 15 from 16 and sensitivity analysis was performed for the discrepancy of total plant count of electrical cabinets. The sensitivity analysis provided in the RAI 28.k submittal (ADAMS Accession No. ML14038A019) demonstrated that the associated discrepancy had an insignificant impact on the Fire PRA.

Therefore, this change is not included in the updated fire PRA risk evaluation in support of the NFPA 805 LAR. This change will be incorporated in conjunction with other future changes as appropriate.

E1-3 Response to Request for Additional Information d) For RAI Responses dated November 12, 2013: (ADAMS Accession No. ML13318A027) i)

PRA RAI 17.d - The ignition frequency and suppression terms for the Turbine Building Collapse scenarios have been updated in accordance with the response to PRA RAI 17.d (ADAMS Accession No. ML14147A368).

ii) PRA RAI 33.c - See response to PRA RAI 33.c.01 (ADAMS Accession No. ML14147A368) for a discussion and clarification of the methodology used for the MCR Abandonment analysis.

e) For RAI responses dated September 16, 2013, October 30, 2013, November 12, 2013 and April 23, 2014:

i)

FM RAI 01.b - The updated baseline results reflect the response specified in FM RAI 01.b (ADAMS Accession No.ML14038A019).

ii) FM RAI 01.c - The updated baseline results reflect the response specified in FM RAI 01.c (ADAMS Accession No. ML14038A019).

iii) FM RAI 01.d - The updated baseline results reflect the response specified in FM RAI 01.d (ADAMS Accession No.ML14038A019). The response to FM RAI 01.d identified an implementation item to be included in Attachment S, Table S-3. This item addresses the amount of allowed combustible material to bring into the main control room.

Based on this response there is no model update required. An updated Attachment S is provided with this response to reference this new implementation item along with adding back other implementation items from previous RAIs (FM 01.d (ADAMS Accession No. ML13318A027), PROG 05 (ADAMS Accession No. M114038A019),

FPE 05 (ADAMS Accession No. ML14038A019) and FPE 09 (ADAMS Accession No. ML14038A019)).

iv) FM RAI 01.h - The updated baseline results reflect the response specified in FM RAI 01.h (ADAMS Accession No. ML13318A027).

v)

FM RAI 01.i - The updated baseline results reflect the response specified in FM RAI 01.i (ADAMS Accession No. ML13318A027).

vi) FM RAI 08 - The updated baseline results reflect the response specified in FM RAI 08 (ADAMS Accession No. ML14114A550).

The updated base risk results includes the composite effect from the RAI responses referenced above, with the exception of PRA 28.k above, which has been judged to have insignificant impact on the risk results and FM 01.d which includes a new implementation item to address the control of the amount of transient combustible materials in the main control room.

Updated total plant, Fire PRA, and delta risk values are included in the updated LAR Attachment W which is included as an attachment to the transmittal of this RAI. Due to the update of plant risk results, Attachment W is also provided to update the ignition frequency sensitivity originally provided. An updated Attachment S is also provided in response to PRA 36.e.iii. Revised NFPA 805 LAR, Table C-2 in Attachment C is provided to reflect changes resulting from E1l-4 Response to Request for Additional Information the update of the Fire PRA associated with the RAIs. Also, reviews have determined there are no revisions to Attachment G that are necessary to account for recovery actions that are required for risk or defense in depth. Based on the nature of the changes involved with previous RAI responses, there have been no changes to the current VFDR dispositions as identified in Table C-1 found in Attachment C. Also, no VFDRs have been added or deleted. As a result, it is not necessary to revise Table C-1.

After a review of Attachment W, Table W-6 and discussions with the NRC, further review of the total additional risk of Recovery Actions was required. The current additional risk of recovery actions was taking credit for the non VFDR risk reduction modifications. Elimination of this credit provides a clearer identification of the risk associated with the credited recovery actions. As such, this additional credit has been removed. When this is done, the additional risk of recovery action increases to 9.98E-06/3.49E-07 and 1.54E-05/6.56E-07 for Unit 1 CDF/LERF and Unit 2 CDF/LERF, respectively. This results in the Unit 2 CDF additional risk of recovery action being in Region I of RG 1.174 and the Unit 1 CDF additional risk of recovery action being right at the threshold of going into Region I. Based on these results, the additional risk of recovery action was revisited to address this concern.

The potential risk of each recovery action is currently bounded by the total delta risk of the Fire Area including all VFDRs. To reduce the conservatism associated with this approach, the additional risk of recovery actions was calculated independently rather than using the bounding value.

To calculate the risk of recovery actions per scenario, a new compliant case (compliant with respect to recovery actions and recovery action related to VFDRs only) was created in which the variant case was modified to set the recovery action failure probability to zero and to set only VFDRs associated with the recovery action to their random failure probability. This new compliant case scenario was then quantified. The delta between the variant case and the new compliant case for these scenarios represents the additional risk of the recovery actions.

All updates to the analysis, including those that included risk result changes, were made using methods previously identified in the NFPA 805 LAR or subsequent RAI responses. A key method that was used in the post LAR revision 01 submittal was the credit taken for the application of non-suppression probabilities in lieu of the removal of the electrical cabinet severity factor method. PRA RAI 01 discussed the use of this approach in the context of the sensitivity evaluation performed for the removal of panel factors. This methodology later became part of the of the baseline Fire PRA analysis as the panel factor removal was incorporated into the baseline Fire PRA model. Other PRA refinements consistent with those used elsewhere in the analysis supporting the original LAR revision 01 submittal were incorporated as needed to reduce the contribution of scenarios for which risk increases resulted from the resolution of the various RAIs.

NFPA 805 Performance Based Standard for Fire Protection for Liqht Water Reactor Generatinq Plants Attachment V-Fire PRA Quality

Southern Nuclear Operating Company Aftachment V - Fire PRA Quality Southern Nuclear Operating Company Attachment V - Fire PRA Quality V.

Fire PRA Quality 2932 Pages Attached I Rev Okj Page V-1

Southern Nuclear Operating Company Attachment V - Fire PRA Quality V.1 Fire PRA Quality In accordance with RG 1.205 position 4.3:

"The licensee should submit the documentation described in Section 4.2 of Regulatory Guide 1.200 to address the baseline PRA and application-specific analyses. For PRA Standard "supporting requirements" important to the NFPA 805 risk assessments, the NRC position is that Capability Category II is generally acceptable. Licensees should justify use of Capability Category I for specific supporting requirements in their NFPA 805 risk assessments, if they contend that it is adequate for the application. Licensees should also evaluate whether portions of the PRA need to meet Capability Category Ill, as described in the PRA Standard."

The FNP Fire PRA has undergone a RG 1.200, Revision 2, Peer Review against the ASME PRA Supporting Requirements (SRs) by a team of knowledgeable industry (vendor and utility) personnel. The review was conducted by the Westinghouse Owners Group in October 2011 under LTR-RAM-II-12-007, "Fire PRA Peer Review against the Fire PRA Standard Supporting Requirements from Section 4 of the ASME/ANS PRA Standard for the Farley Nuclear Plant Fire Probabilistic Risk Assessment" in accordance with NEI 07-12 as endorsed by RG 1.200 Rev 2. The conclusion of the review was that the FNP methodologies being used were appropriate and sufficient to satisfy the ASME/ANS PRA Standard RA-Sa-2009. The review team also noted that NUREG/CR-6850 methodologies were applied correctly.

The summary of the peer review findings exhibited the following statistics for the evaluation of elements to the combined PRA Standard. For the FNP Fire PRA, 88% of the SRs were assessed at Capability Category II or higher, including 8% of the SRs being assessed at Capability Category I1l. The FNP Fire PRA had an additional 5% of the applicable SRs assessed at the Capability Category I level. The Fire PRA was found to not meet 7% of the applicable SRs.

The Westinghouse Peer Group concluded that the Farley Fire PRA is consistent with the ASME/ANS PRA Standard and supports risk-informed applications. As a result of the peer review and the fire risk evaluation process the FNP Fire PRA has undergone additional model refinements. These refinements were made consistent with the methodologies that were reviewed during the FNP Peer Review.

This attachment provides a detailed assessment of each of the findings identified by the Peer Review team. Table V-1 lists each finding and provides the FNP disposition of the finding. Table V-2 lists each SR that was MET at a Capability Category I level and the disposition by FNP as to why that Capability Category level is acceptable.

The Peer Review Reports (LTR-RAM-II-12-007) will be available for NRC review.

V.2 Sensitivity of Fire PRA Methods During the development of the FNP Fire PRA, SNC applied an alternate analysis method to NUREG/CR-6850. SNC determined that the approach taken by this alternate method provides a more realistic representation in the FNP Fire PRA model.

I I Rev Oki Page V-2

Southern Nuclear Operating Company Attachment V - Fire PRA Quality V.2.1 Electrical Cabinet Fire Severity Methodology The Electrical Cabinet Severity Factor Methodology has been removed from the Farley Fire PRA. As such, the sensitivity on this method is no longer required.

V.2.2 Sensitivity Analysis for Use of Generic Ignition Frequency NUREG/CR-6850 provides generic ignition frequencies as identified in task 6. These frequencies have since been reviewed and updated as part of FAQ 08-0048. The updated generic frequencies are documented in NUREG/CR - 6850 Supplement 1, Chapter 10. NUREG/CR-6850 Supplement 1 states that if the analyst uses these new generic frequencies then a sensitivity study must be done. The sensitivity is only required for bins, as defined in Task 6 of NUREG/CR - 6850, that have an alpha value of less than or equal to 1 in EPRI 1016735. This is discussed in more detail in note 10 of NUREG/CR - 6850 Supplement 1.

As discussed in Farley Fire PRA Task 1 & 6, Plant Partitioning and Fire Ignition Frequency, PRA-BC-F-1 1-009, the generic frequencies from NUREG/CR - 6850 Supplement 1 were Bayesian updated to reflect plant specific data. Table V. 2-1 includes the results of the sensitivity. For the purposes of this sensitivity, the Unit 1 Train A and B CDF/LERF risk model is used. Similar results/insights are expected for Unit 2 CDF/LERF.

Note 2: The ACDF/LERF for the Base and Sensitivity are <0. With an increase in total risk, there would also be an increase in the A risk, however, since both are <0 the delta is not provided.

It should be noted that an increase in CDF/LERF is expected based on the type of sensitivity being performed. One of the ignition frequency Bins, Bin 15 - Electrical Cabinets, is included as part of this analysis. The ignition frequency for Bin 15 had a decrease of approximately a factor of 2 between NUREG/CR-6850 and NUREG/CR-6850 Supplement 1. The Farley Fire PRA results are mostly driven by scenarios that have a Bin 15 ignition source, so it follows that an increase is seen in this sensitivity.

Rev Okj Page V-3

Southern Nuclear Operating Company Attachment V - Fire PRA Quality Table V.2-1 shows that the total fire CDF results are 1.18E-04-1-T-7E--04 or a total plant risk of 1.46E-041.45E 0Q4 for CDF, which includes the contribution of the full power internal events and seismic risk. The delta CDF for this sensitivity is <0 3.67E= 05.

Table V.2-1 shows that the total fire LERF results are 8.37E-068.19E 06 or a total plant risk of 8.70E-068.52E 06 for LERF, which includes the contribution of the full power internal events and seismic risk. The delta LERF for this sensitivity is <0 2.20E= 05.

For the sensitivity analysis, based on the total plant CDF of 1.46E-041 45E -04 the delta CDF should be in the Region III range. The delta CDF for this sensitivity is within the Region III range. Based on the total plant LERF of 8.70E-06&.52E 06 the delta LERF should be in the Region II range. The delta LERF for this sensitivity is within the Region II range.

Though the ACDF/ALERF are within the acceptable guidelines of RG 1.174, a review of the contributors by fire area for this sensitivity is provided below. This review includes the Defense in Depth actions currently identified in the Fire Risk Evaluations for areas with high risk contributions.

Additionally, the MCR equipment rooms are normally unoccupied and NSP should be associated with the electrical equipment room vs. the control room. If the control room lambda is used, a basis should be developed why the control room lambda is more appropriate than the electrical cabinet lambda.

Utility Comment: This specific F&O is inconsistent with F&O FSS-E3-01. The indicated resolution for FSS-E3-01 states in part that the analysis documentation should be enhanced to note that methods for developing the statistical representation of the uncertainty intervals and mean values currently do not exist. However, F&O FSS-H5-01 then asks to undertake evaluations to address uncertainty. These this latter F&O should be revised so that it is consistent with FSS-E3-01.

Response: The F&Os address the specific SR requirements. The response to F&O FSS-E3-01 may be used to justify the treatment of uncertainty for FSS but the F&O documents compliance with the standard and as such remains.

Southern Nuclear Operating Company Attachment V - Fire PRA Quality Table V-1 Fire PRA Peer Review - Facts and Observations SR Topic Status Finding/Observation Disposition PP-B3 The Farley Fire PRA did not contain sufficient information on scenario development with respect to the crediting of fire barriers.

Closed SNOC has not provided sufficient evidence that Fire Zone PAUs were evaluated for fire resistance capabilities of barriers, nor was there sufficient evidence that credited spatial separations were analyzed.

Specific examples are cited in PRA-BC-F-1 1-001, Section 2.2, for PAUs that use "natural divisions." The document cites that the lack of fire barriers between these PAUs will be evaluated during the MCA.

However, the MCA analysis appears to only discuss hot layer issues, and does not consider whether a fire propagates outside of the PAU or if there is a zone of influence and target damage outside of the PAU.

Another example of where spatial separation is credited is Tool Room 0441.

The Farley scenario development report has been updated to provide more details on the scenario development based on the ignition source and target identification process. This can be found in the Farley Scenario Development report, PRA-BC-F-11-014, section 3.1.1. The impact on the Hot Gas Layer and Multi-Compartment Analysis has also been revisited to assure that the boundaries of the rooms have been adequately represented in the calculation of the volumes.

Full room burnout scenarios are developed and quantified, but without sufficient evidence that fire barriers or spatial separation issues have been evaluated. It appears that specific PAUs are screened from having multi-compartment impacts without consideration of fire propagation or ZOs impact across spatial divisions.

SNOC has presented a plan to resolve the Fire Zone PAU vs. Fire Area PAU issue. Implementation of this plan is sufficient to address the issues identified in PP-B2 and PP-B33. In the plan, Fire Areas will be treated as PAUs. Particularly, SNOC staff have acknowledged that for "full burn" and "base case" fire scenarios, they will review and document the capabilities of barriers and the appropriateness of credited spatial separations, and will not inappropriately credit barriers or spatial separations for fire scenarios. The plan includes the following:

1. Those APs that have one or more boundaries I

There will be confirmation that the results of the above have been observed and documented.

Enhance the documentation to acknowledge the crediting of non-rated physical boundaries and provide a basis recognizing that the justification will rely on physical observations during plant walkdowns or through equivalent means as well as general construction methods (masonry block wall, concrete walls, etc.).

3.

Address the nature and consequence of anticipated fire events for all APs for which explicit fire scenarios are not developed (base cases) and confirm that the results are appropriate given the boundaries for the AP.

4.

Confirm that bounding room burn-out cases are not used for any APs that are not fully bounded by physical fire barriers, and that there is a justification for crediting those physical barriers.

5.

Confirm that the resulting analysis does not change (reduce) the level of resolution associated with the existing fire scenarios developed to support the requirements of SRs associated with FSS.

clarification.

F&O PP-B3-01 identifies an acceptable plan to address the technical issues around the definition of PAUs, that Fire Areas, not Fire Zones, form the basis for PAUs.

Fire Zones and similar entities will be identified as "Administrative Partitions" (AP). Since the term "Physical Analysis Unit" or PAU is extensively in Fire PRA documentation to describe Fire Zone PAUs, all Fire PRA documents should be reviewed and revised to call these compartments Administrative Partition.

Furthermore, the term "Administrative Partition" (AP) should be defined in the PP documentation and the APs descriptions (formally, Fire Zone PAUs), should be retained.
