The Attachment W pages to this letter contain security related information. Withhold from public disclosure in accordance with 10CFR 2.390. When the Attachment W pages are removed, this document is no longer security related.

Document Control Desk Page 2 March 23, 2016 The reference letters comprise in their entirety Duke Energy's request for NRC review and approval for adoption of a new fire protection licensing basis which complies with the requirements in 10 CFR 50.48(a), 10 CFR 50.48(c), and the guidance in Regulatory Guide (RG) 1.205, "Risk-Informed, Performance-Based Fire Protection for Existing Light-Water Nuclear Power Plants", Revision 1, dated December 2009. The September 25, 2013 reference LAR was developed in accordance with the guidance contained in Nuclear Energy Institute (NEI) 04-02, "Guidance for Implementing a Risk-Informed, Performance-Based Fire Protection Program Under 10 CFR 50.48(c)", Revision 2.

The purpose of this LAR supplement is twofold:

1. Duke Energy is resolving a discrepancy that was recently discovered in the NFPA 805 Safe Shutdown Analysis. The NFPA 805 Nuclear Safety Capability Assessment was discovered to contain a legacy discrepancy that does not match the current Safe Shutdown Analysis. This led to an omission of a Variance From Deterministic Requirement (VFDR) from the September 25, 2013 reference LAR. This discovery was entered into the Catawba Corrective Action Program on February 22, 2016.

Since that time, Duke Energy has performed an extent-of-condition evaluation (no additional discrepancies were found) and has revised the affected NFPA 805 LAR document pages. These pages are contained herein and include: 1) a Compact Disc (CD) copy of entire Attachment C, "NFPA 805 Ch 4 Compliance (NEI 04-02 Table B-3)" (a CD copy is being provided as this entire attachment was affected by repagination and comprises 697 pages; the actual revised pages are 19, 24, 31, and 36); and 2) a paper copy of the revised pages of Attachment W, "Fire PRA Insights".

The revised Attachment C and Attachment W pages have the revisions designated by revision bars.

2. Duke Energy is revising a regulatory commitment associated with the mitigation of internal flooding concerns in the Auxiliary Feedwater (AFW) pump rooms. The revised commitment is shown on the revised page of LAR Attachment S, "Modifications and Implementation Items", which has the revision designated by revision bar. Also included is a re-transmittal of the entire final LAR Attachment S, which is designated as Revision 5 and has all revision bars removed. This

• constitutes the final clean copy of Attachment S for referencing in the Facility Operating Licenses. The revised Attachment W pages resulting from this revised commitment have the revisions designated by revision bars.

Duke Energy has determined that the revised Attachment W pages should be considered as Sensitive Unclassified Non-Safeguards Information (SUNSI) and has designated these pages as so. Duke Energy is requesting that the enclosed Attachment W pages be withheld from public disclosure in accordance with 10 CFR 2.390.

The Attachment W pages to this letter contain security related information. Withhold from public disclosure in accordance with 10 CFR 2.390. When the Attachment W pages are removed, this document is no longer security related.

Document Control Desk Page 3 March 23, 2016 The conclusions of the No Significant Hazards Consideration and the Environmental Consideration contained in the September 25, 2013 reference LAR are unaffected by this LAR supplement.

Except as indicated above, there are no regulatory commitments contained in this letter or its enclosure.

Pursuant to 10 CFR 50.91, a copy of this LAR supplement is being sent to the appropriate State of South Carolina official.

Inquiries on this matter should be directed to L.J. Rudy at (803) 701-3084.

I declare under penalty of perjury that the foregoing is true and correct.

Executed on March 23, 2016.

Very truly yours,

Duke Energy Carolinas, LLC Attachment S - Modifications and Implementation Items Table S-3, Items provided below are those items (procedure changes, process updates, and training to affected plant personnel) that will be completed prior to the implementation of new NFPA 805 fire protection program. This will occur within 180 days after issuance of the license amendment unless that date falls within a scheduled refueling outage. Then, implementation will occur within 60 days after startup from that scheduled refueling outage. Note Item 13 is associated with modifications in Table S-2b and will be completed 180 days after completion of the last risk related modification .

.Table S-3 Implementation Items Item Unit Description LAR Section I Source 1, 2 Perform the following recommendations from the Radiological Release 4.4.2 and Attachment E Evaluation:

1. Within each yard area fire strategy, identify radiologically

.controlled area boundaries within ~he 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: hatches, passage doors, and roll-up.doors.

2. Enhance the appropriate existing procedures or guidelines, or create a new procedure or guideline, to include more detail on the control measures usedto 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-29) to instruct Radiation Protection personnel to respond to fires where there are radiological concerns inside and outside the Protected Area.

4. Enhance the appropriate existing procedures or guidelines, or create a new procedure or guideline, to include guidance for crossing RCA/Radioactive Control Zone boundaries including escape routes.

5. Create new fire strategies for yard areas that contain RCAs.

This includes the following:

• Retired Steam Generator Storage Facility (Building 7777)

Revs Page S-7

Duke Energy Carolinas, LLC Attachment S- Modifications and Implementation Items Table S-3 Implementation Items Item Unit Description LAR Section I Source

• Radiation Materials Control Building (Building 7767)

• Hold-Up Ponds

• Radiography Vault

• Radioactive Materials Containers

• Tents Containing Radioactive :Material

• Mixed Waste Storage

• ISFSI Storage of non-ISFSI Radioactive Materials

6. Within each fire strategy, identify the Radiologically Controlled Area (RCA) or Radioactive Control Zone in the written text.

7. Fire Brigade training will be revised to ensure the new guidance proposed in Recommendations 2, 3 and 4 for radioactive release is covered during the established training interval.

8. Add a standard statement for smoke and water runoff to all radiologically controlled area fire strategies to prompt measures to avoid radioactive release.

9. Incorporate all fire fighting strategies into the electronic .

records management retrieval system (internally referred to as NEDL). This will provide consistency for current users and the ability to conduct effective reviews to ensure all radioactive release recommendations have been incorporated.

10. 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.

11. 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. Attachment A contains a flow chart of the various considerations needed for administrative controls that can be directed via one or more plant procedures depending upon the performing group(s).

• Activities in affected fire areas should be rescheduled to non-Higher Risk Plant Operating States (HRPOS's) periods.

13 1, 2 Following installation of the risk related modifications and the as-built 4.8.2 installation details, additional refinements surrounding the modification and any procedural implementation items (Table S~3 Items 12 and 16) will be incorporated into the Fire PRA model and Internal Events model, as required. 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.

14 1, 2 Develop formal training program for nonfire brigade personnel that Attachment A, 3.4.3(b) respond to a fire incident.

15 1, 2 4.7.3 Revise the QA Topical, as appropriate, to update the definition of QA 3 to match post NFPA 805 criteria. QA Topical currently defines QA 3 as:
