By letter dated September 26, 2013 (Reference 1), Duke Energy submitted a LAR to adopt a new, risk-informed, performance-based (RI-PB) fire protection licensing basis for the MNS Units 1 and 2.
On December 31, 2013 (Reference 2), the NRC requested supplemental information in order to make the September 26, 2013, LAR complete and acceptable for review by the NRC. By letter dated January 8, 2014 (Reference 3), Duke Energy provided the requested supplemental information to the NRC. By letter dated January 15, 2014 (Reference 4), the NRC accepted the September 26, 2013, LAR for review.
By letters dated August 28, 2014, and October 27, 2014 (References 5 and 7, respectively), the NRC requested additional information (RAI) in order to complete their review of the September 26, 2013, LAR. Those letters grouped the RAls into 60-day, 90-day, 120-day, and radiation release responses. Duke Energy provided the 60-day, 90-day, and some of the 120-day RAI responses by letters dated October 13, 2014, November 12, 2014, and December 12, 2014 (References 6, 8, and 9, respectively). Responses to the radiation release RAls and some of the remaining 120-day RAls were provided by letter dated January 26, 2015 (Reference 10).
By letter dated February 27, 2015 (Reference 11 ), Duke Energy submitted responses to all remaining first-round RAls, excluding Probabilistic Risk Assessment (PRA) RA! 03. This submittal also included revised responses to PRA RAI 12 and PRA RAl 17. By letter dated March 13, 2015 (Reference 12), Duke Energy submitted response to PRA RAl 03.
By letters dated May 8, 2015, June 18, 2015, and August 18, 2015 (References 13, 14, and 16, respectively), the NRC submitted second-round RAls to complete their review of the September 26, 2013, LAR.
By letters dated July 15, 2015 (Reference 15), August 20, 2015 (Reference 17), and September 9, 2015 (Reference 18), Duke Energy submitted responses to the second-round RAIs.
By letter dated October 1, 2015 (Reference 19), Duke Energy submitted several administrative changes to the LAR submittal package.
By email dated October 28, 2015, the NRC requested a clean copy of Attachment S of the LAR and requested final administrative changes to Attachment M of the LAR.

Duke Energy Carolinas, LLC                           Attachment IVl- License Condition Changes Replace the current MNS fire protection license condition 2.C.(4) for both Unit 1 and Unit 2 with the standard license condition in Regulatory Position 3.1 of RG 1 .205, modified as shown below.
Duk~e Energy Carolinas, LLC shall implement and maintain in effect all provisions of the approved fire protection program th'at comply with 10 CFR 50.48(a) and 10 CFR 50.48(c), as specified in the licensee amendment request dated September 26, 2013, as supplemented by letters dated January 8, 2014, October 13, 2014, November 12, 2014, December 12, 2014, January 26, 2015, February 27, 2015, March 13, 2015, July 15, 2015, August 20, 2015, September 9, 2015, October 1, 2015, and January 14, 2016, and as approved in the safety evaluation dated       ______.Except            where NRC approval for changes or deviations is required by 10 CFR 50.48(c), and provided no other regulation, technical specification, license condition or requirement would require prior NRC approval, the licensee may make changes to the fire protection program without prior approval of the Commission if those changes satisfy the provisions set forth in 10 CFR 50.48(a) and 10 CFR 50.48(c), the change does not require a change to a technical specification or a license condition, and the criteria listed below are satisfied.
Risk-Informed Changes that May Be Made Without Prior NRC Approval A risk assessment of the change must demonstrate that the acceptance criteria below are met. The risk assessment approach, methods, and data shall be acceptable to the NRC and shall be appropriate for the nature and scope of the change being evaluated be based on the as-built, as-operated, and maintained plant; and reflect the operating experience at MNS. Acceptable methods to assess the risk of the change may include methods that have been used in the peer-reviewed fire PRA model, methods that have been approved by NRC through a plant-specific license amendment or NRC approval of generic methods specifically for use in NFPA 805 risk assessments, or methods that have been demonstrated to bound the risk impact.
a) Prior NRC review and approval is not required for changes that clearly result in a decrease in risk. The proposed change must also be consistent with the defense-in-depth philosophy and must maintain sufficient safety margins. The change may be implemented following completion of the plant change evaluation.
b) Prior NRC review and approval is not required for individual changes that result in a risk increase less than 1 xl0-F/year (yr) for CDF and less than 1 xl 0-8 /yr for LERE. The proposed change must also be consistent with the defense-in-depth philosophy and must maintain sufficient safety margins. The change may be implemented following completion of the plant change evaluation.
Other Changes that May Be Made Without Prior NRC Approval
: 1) Changes to NFPA 805, Chapter 3, Fundamental Fire Protection Program Prior NRC review and approval are not required for changes to the NFPA 805, Chapter 3, fundamental fire protection program elements and design requirements for which an engineering evaluation demonstrates that the alternative to the Chapter 3 element is Rev 4                                                                                  Page M-2

Duke Energy Carolinas, LLC                          Attachment M - License Condition Changes functionally equivalent or adequate for the hazard. The licensee may use an engineering evaluation to demonstrate that a change to an NEPA 805, Chapter 3, element is functionally equivalent to the corresponding technical requirement. A qualified fire protection engineer shall perform the engineering evaluation and conclude that the change has not affected the functionality of the component, system, procedure, or physical arrangement, using a relevant technical requirement or standard.
The licensee may use an engineering evaluation to demonstrate that changes to certain NFPA 805, Chapter 3, elements are acceptable because the alternative is 'adequate for the hazard." Prior NRC review and approval would not be required for alternatives to four specific sections of NFPA 805, Chapter 3, for which an engineering evaluation demonstrates that the alternative to the Chapter 3 element is adequate for the hazard. A qualified fire protection engineer shall perform the engineering evaluation and conclude that the change has not affected the functionality of the component, system, procedure, or physical arrangement, using a relevant technical requirement or standard. The four specific sections of NFPA 805, Chapter 3, are as follows:
SFire Alarm and Detection Systems (Section 3.8);
[]Automatic and Manual Water-Based Fire Suppression Systems (Section 3.9);
       *Gaseous Fire Suppression Systems (Section 3.10); and,
[]Passive Fire Protection Features (Section 3.11).
: 2) Fire Protection Program Changes that Have No More than Minimal Risk Impact Prior NRC review and approval are not required for changes to the licensee's fire protection program that have been demonstrated to have no more than a minimal risk impact. The licensee may use its screening process as approved in the NRC safety evaluation report dated   _______to        determine that certain fire protection program changes meet the minimal criterion. The licensee shall ensure that fire protection defense-in-depth and safety margins are maintained when changes are made to the fire protection program.
This License Condition does not apply to any demonstration of equivalency under Section 1.7 of NFPA 805.
Transition License Conditions
: 1) Before achieving full compliance with 10 CFR 50.48(c), as specified by (2) below, risk-informed changes to the licensee's fire protection program may not be made without prior NRC review and approval unless the change has been demonstrated to have no more than a minimal risk impact, as described in (2) above.
: 2) The licensee shall implement the modifications to its facility, as described in Attachment 5, Table S-2, "Plant Modifications Committed," of Duke Energy letter dated January 14, 2016, to complete the transition to full compliance with 10 CFR 50.48(c) by the end of the Unit 1 refueling outage currently scheduled for Spring 2016 (1EOC24). The licensee shall maintain appropriate compensatory measures in place until completion of these modifications.

Implementation Item 1,2 is associated with modifications in Table S-2 andl will be completed 180 days after completion of the last risk related modification. Implementation Item 19 is associated with thermoplastic cable analysis and will be completed by June 30, 2017.
License condition 2.C.(4) for both Unit 1 and Unit 2 shall be superseded:
2.C.(4) Fire Protection Program Duke Energy Carolinas, LLC shall implement and maintain in effect all provisions of the approved fire protection program as described in the Updated Final Safety Analysis Report for the facility and as approved in the SER dated March 1978 and Supplements 2, 5, and 6 dated March 1979, April 1981, and February 1983, respectively, and the safety evaluation dated May 15, 1989, subject to the following provisions:
The licensee may make changes to the approved fire protection program without prior approval of the Commission only if those changes would not adversely affect the ability to achieve and maintain safe shutdown in the event of a fire.
It is Duke Energy's understanding that implicit in the revocation of this license condition, all prior Fire Protection Program Safety Evaluations and commitments have been superseded in their entirety by the revised license condition.
No other license conditions need to be revised or superseded.
MNS implemented the following process for determining that these are the only license conditions required to be either revised or superseded to implement the new fire protection program which meets the requirements in 10 CFR 50.48(a) and 50.48(c):
* A review was conducted of the MNS Renewed Facility Operating License NPF-9 and NPF-17, by MNS licensing staff and the NFPA 805 Transition Team. The review was performed by reading the Operating License and performing electronic searches. Outstanding LARs that have been submitted to the NRC were also reviewed for potential impact on the license conditions.

: 1. Within each yard area fire strategy, identify RCA boundaries within the strategy and any potential escape paths. This includes building sumps and storm drains, where applicable. For consistency, it is recommended that even hardened barriers are identified. Examples of these would include: the containment hatch, fuel handling access hatch, water tight doors to the outside, as well as passage doors and roll-up doors.
: 2. Enhance Fire Brigade Guidelines (Procedure RP/0/A/5700/025, Fire Brigade Response) to include more detail on the control measures used to maintain radioactive release limits where monitoring cannot be accomplished. Examples include:
                                       = Water fog streams used for smoke scrubbing.
* Controlling water runoff during fire suppression activities.
[] Covering drains and other similar containment measures.
: 3. Enhance Fire Brigade Guidelines (Procedure RP/0/A/5700/025, Fire Brigade Response) to instruct Radiation Protection personnel to respond to all fires within RCAs inside and outside the Protected Area.
: 4. Enhance Fire Brigade Guidelines (Procedure RP/0/A/5700/025, Fire Brigade Response) to include guidance for crossing RCA/RCZ boundaries including escape routes.
: 5. Develop a Standard Operating Guideline (SOG) for fires involving contaminated material outside of the power block.
: 6. Create new fire strategies for yard areas that contain RCJAs.
_This includes Radwaste Facility, Warehouse 7, and the open yard areas where tanks and land-sea containers are stored.

: 7. Within each fire strategy, identify the RCA or Radioactive Control Zone in the written text.
: 8. Fire Brigade training will be revised to ensure the new guidance included in Procedure RP/0/A/5700/025, Fire Brigade Response for radioactive release is covered during the established training interval.
: 9. Add a standard statement for water runoff to all RCA fire strategies similar to the caution contained for smoke removal.
: 10. Incorporate all fire fighting strategies into the electronic records
                                    *management retrieval system (internally referred to as NEOL).
This will provide consistency for current users and the ability to conduct effective reviews to ensure all radioactive release recommendations have been incorporated.
: 11. Add an appendix to the fire strategies for building sump drainage and site storm drains. This is NOT intended to be a detailed plan, but a site overview that identifies areas where runoff has the potential to route to a storm drain or an automatic sump that will pump without radiation monitoring.
: 12. Develop a SOG to address owner controlled area RCAs. This would include, for example, Warehouse 7 and outage equipment stored there.
: 13. Develop administrative guidance, in collaboration with radiation protection, to support ensuring that radioactive release(s) do not exceed limits in the event of a fire in areas where engineering controls will not contain the potential release.

In addition, a verification will be performed to confirm that the risk results are not appreciably changed. If the as-built change-in-risk estimates exceed the RG 1.174 acceptance guidelines, the responsible feature will be identified and evaluated. Actions taken to address such a case may be one or more of the following: 1) implementing additional modifications, 2) refining the analytical estimates, or 3) requesting that exceeding the guidelines be deemed acceptable in a new LAR,.

Guidance in NUREG/CR-6850                           PRA-03.d and other NRC accepted documents will be used to perform the analysis. The impact on the Fire CDF/LERF and the delta CDF/LERF will be reviewed to verify the results are within RG 1.174 acceptance guidelines. An MSO Expert Panel will also be conducted as part of the Fire PRA update. MNS will complete this analysis by June 30, 2017.
If the impact on risk estimates exceed the RG 1.174 acceptance guidelines, actions taken to address this case may be one or more of the following: 1) refining the analytic estimates, 2) communicating to the NRC the need and proposed schedule to implement additional modifications, or
: 3) requesting that exceeding the guidelines be deemed acceptable in a new LAR." Until the post Fire PRA reanalysis is complete and the results are within the RG 1.174 acceptance guidelines, the use of the Fire PRA for self-approval of plant changes affecting the fire protection program will be restricted to changes that are not greater than minimal for the fire areas with greater than 5% thermoplastic cable.
