In accordance with the provisions of Title 10 of the Code of Federal Regulations (10 CFR) 50.90, Tennessee Valley Authority (TVA) requests an amendment to the Renewed Facility Operating License Nos. DPR-33, DPR-52, and DPR-68 for Browns Ferry Nuclear Plant (BFN),

Units 1, 2, and 3, respectively.

U.S. Nuclear Regulatory Commission CNL-18-001 Page 2 May 3, 2018 The proposed amendment modifies the BFN licensing basis regarding the National Fire Protection Association (NFPA) 805 program to provide a correction to previously submitted information.

Reference 1 provided TVAs Fire Protection Report that described BFNs conformance to Appendix R fire protection requirements. Reference 2 provided NRCs approval of TVAs Fire Protection Report. These references included a discussion of the insulating materials that were acceptable for use at BFN.

In Reference 3, TVA submitted a license amendment request (LAR) to adopt NFPA 805 requirements. Reference 4 provided NRCs acceptance of TVAs NFPA 805 fire protection program. In Reference 3, TVA utilized NEI 04-02 guidelines that included Attachment A, Table B-1 Transition of Fundamental Fire Protection Program & Design Elements. In Attachment A, Table B-1, Item 3.3.4, Insulation Materials, was reported as Complies with the NFPA 805 requirements.

TVA requests that the compliance statement be revised to state "Complies with previous approval." This correction is based on the previous NRC approval (Reference 2) for the use of insulating materials that are not currently approved for use with the requirements specified in NFPA 805.

Through information sharing between industry peers, TVA was informed that the definition used in NFPA 805 for Limited Combustibility (Section 3.3.4) was different from that in BTP CMEB 9.5-1. Upon review of the NFPA 805 application, TVA discovered that a discrepancy existed in the NFPA 805 LAR. In Table B-1, Item 3.3.4,"Insulation Materials," TVA reported that BFN "complies" with the NFPA 805 based on the use of noncombustible materials. However, TVA specifications allow the use of materials that are combustible and that may also not meet the NFPA 805 definition of limited combustible. This condition was entered into TVA's Corrective Action Program for tracking and closure purposes. provides the description and evaluation of the requested change. In order to correct the erroneous information in Table B-1, TVA has provided a corrected page with updated information as shown in Enclosure 2. provides a markup of the revised BFN NFPA 805 submittal Appendix A page. provides a clean typed version of the BFN NFPA 805 submittal Appendix A page. provides a markup of the affected pages of the BFN Units 1, 2, and 3 Renewed Operating Licenses. Enclosure 5 provides clean typed pages of the affected pages of the BFN Units 1, 2, and 3 Renewed Operating Licenses.

TVA has determined that there are no significant hazards consideration associated with the proposed change and that the change to the Renewed Operating License qualifies for a categorical exclusion from environmental review pursuant to the provisions of 10 CFR 51.22(c)(9).

U.S. Nuclear Regulatory Commission CNL-18-001 Page 3 May 3, 2018 The BFN Plant Operations Review Committee has reviewed this amendment request and concluded that operation of BFN in accordance with the proposed change will not endanger the health and safety of the public.

Additionally, in accordance with 10 CFR 50.91 (b)(1 ), TVA is sending a copy of this letter and enclosures, to the Alabama State Department of Public Health.

TVA requests NRC approval of this LAR by May 3, 2019 in order to support the implementation of the NFPA 805 program at BFN.

There are no new regulatory commitments contained in this submittal. Please address any questions regarding thi.s submittal to Edward D. Schrull at (423) 751-3850.

I declare under penalty of perjury that the foregoing is true and correct. Executed on this 3rd day of May 2018.

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials 1.0 Summary Description This evaluation supports a request to revise Renewed Facility Operating Licenses (RFOL)

DPR-33, DPR-52, and DPR-68 for Browns Ferry Nuclear Plant (BFN) Units 1, 2, and 3, respectively. The Enclosure to the BFN NFPA License Amendment Request (Reference 1) contained Attachment A, NEI 04-02 Attachment A, Table B-1 Transition of Fundamental Fire Protection Program & Design Elements, Item 3.3.4, Insulation Materials. This item was previously reported as it Complies with the NFPA 805 requirements. These revisions are discussed in Section 2.2 below.

The compliance statement for Item 3.3.4, Insulation Materials, is revised to state, Complies with previous approval. This correction is based on previous NRC approval (Reference 3) for the use of plastics, including insulation, shielding and sound proofing materials, that do not meet the NFPA 805 limited combustible definition. The enclosed discussion shows that the basis for the previous approval is maintained and that the modeling and evaluation of the combustible hazards of these materials continues to provide the proper consideration in the Fire Hazard Analysis for the NFPA 805 licensing basis. This proposed revision markup and clean typed copy are shown in Enclosures 2 and 3 respectively.

2.0 Detailed Description 2.1 Proposed Changes TVA requests that the response to the BFN NFPA Attachment A, Table B-1 Item 3.3.4, Insulation Materials, be revised from complies to Complies with previous approval. A markup and clean copy of the proposed change is provided in Enclosures 2 and 3 respectively.

TVA also requests an amendment to the BFN RFOL, paragraphs 2.C.(13), 2.C.(14), and 2.C.(7) for Browns Ferry Units 1, 2, and 3, respectively as shown below:

CNL-18-001 E1-3 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials 2.2 Reason for the Proposed Change Through information sharing between industry peers, TVA was informed that the definition used in NFPA 805 for Limited Combustibility (Section 3.3.4) was different from that in CMEB-BTP 9.5.1. Upon review of the NFPA 805 application, TVA discovered that a discrepancy existed in the NFPA 805 LAR. In Table B-1, Item 3.3.4,Insulation Materials, TVA reported that BFN "complies" with the NFPA 805 strategies for use of noncombustible materials. However, NRC had previously approved BFN for the current use of insulating materials in Reference 3 for Appendix R requirements.

In order to make the Section 3.3.4, Table B-1 entry accurate, TVA requests a revision to the entry to state, Complies with previous approval. This condition is considered to be an isolated situation limited to this entry.

3.0 Technical Evaluation 3.1 Technical Basis for the Request The current NFPA 805 requirements (Reference 4) do not allow the use of some of the previously approved elastomeric insulation materials because they would exceed the 3,500 BTU/lb requirement. TVA submitted the BFN Fire Protection Report and a comparison of the BFN Fire Protection Program to NRC Branch Technical Position (BTP) CMEB 9.5-1 in Reference 2 that included a discussion of plastic, insulation, and flame retardant materials. In to Reference 2, TVA provided a comparison of the BFN Fire Protection Program to BTP CMEB 9.5-1 (Reference 5). In response to NRC Guideline C.5.d(3), Control of Combustibles, TVA provided the following response:

(3) The use of plastic materials inside buildings is controlled by the Fire Protection Plan, Section 7.2 (Reference 1). Plastic materials used at BFN include pipe insulation (Foam Plastic), cable insulation (PVC etc.), light covers etc. The combustible hazards of these materials have been considered in the Fire Hazards Analysis.

NRC approval of the BFN Fire Protection Report was provided in NRC Safety Evaluation Report (SER) (Reference 3). Section 2.9, Control of Combustibles, of the SER states; Based on the licensees submittal, the staff concluded that combustibles have been separated from safety-related systems or provided with suppression in accordance with the guidelines of BTP CMEB 9.5-1, Section C.5.d, and such separation, therefore, is acceptable.

Section 2.9 of the SER did not specifically address BFNs control of plastic materials, but the SER concluded in Section 3.0; The licensees Fire Protection Plan and Fire Hazard Analysis described in BFN-FPR was reviewed and found acceptable.

The technical basis of the original approval remains valid in that under 10 CFR 50 Appendix R, BFN controlled the use of plastic materials by the Fire Protection Plan (i.e., Appendix R Fire Protection Report, Section 7.2). BFN maintained consideration for combustible thermal insulation materials in the Appendix R Fire Hazard Analysis per the evaluations in the Combustible Load Table calculation.

CNL-18-001 E1-4 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials Under the NFPA 805 licensing basis, combustible materials added by plant modifications are controlled by the NFPA 805 Fire Protection Program Change Impact Screening Process procedure whereby combustible materials including combustible thermal insulation are considered for impact to the NFPA 805 Fire Protection Program. Secondary combustibles such as foam insulation (e.g., cellular elastomeric) are considered in the Fire Hazard Analysis by fire scenario development (i.e., fire modeling) and fire risk evaluations. Secondary combustibles, such as combustible thermal insulation, are considered in the fire scenario development by the use of an increased heat release rate and zone of influence (ZOI) where appropriate for the fire scenarios affected by the secondary combustibles. The increased ZOI and resulting Fire PRA target damage are reflected in the performance-based, risk-informed fire risk evaluations. This modeling and evaluation of the combustible hazards of these materials continues to provide the proper consideration in the Fire Hazard Analysis for the NFPA 805 licensing basis. Therefore, BFN continues to meet the basis for the previous approval.

3.2 Nuclear Safety and Radiological Release Performance Criteria The selection and application of thermal insulation material is controlled per the TVA General Specification G-82, Installation, Modification and Maintenance of Insulation and Site Specification N1M-001 Installation, Modification, and Maintenance of Thermal and Antisweat Insulation. The Fire PRA development requires the inclusion of the effect of intervening or secondary combustibles to be documented and included in the analysis where determined to have fire effects as part of the performancebased approach. TVA Fleet Procedures that govern the Engineering Change Process are in place to review future installation impacts to the Fire Protection Program and Fire PRA, resulting in updates to the applicable analyses and calculations as required.

Secondary combustibles with the potential to affect the Fire PRA are considered in the fire scenario development performed in fire modeling. The supporting analyses and existing fire scenarios either (1) already consider the thermal insulation as a secondary combustible, (2) use bounding conservative target sets (i.e., expanded ZOIs due to the ignition of secondary combustibles in the area would not fail additional Fire PRA targets), or (3) the thermal insulation is out of the ZOI of any nearby fixed or transient ignition sources.

The use of insulation material other than non-combustible and more than limited combustible has no impact on the radiological release performance criteria. The radiological release review was performed based on the manual fire suppression activities in areas containing or potentially containing radioactive materials and is not dependent on the type of thermal insulation material.

The insulation material, regardless of heat contribution value, does not change the radiological release evaluation performed that concluded that potentially contaminated water is contained and smoke is monitored. The insulation materials do not add radiological materials to the area or challenge system boundaries.

CNL-18-001 E1-5 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials 3.3 Safety Margin The insulation material, and specifically the increase in heat contribution in conjunction with the limited applications, does not compromise automatic fire suppression functions, manual fire suppression functions, or post-fire safe shutdown capability as previously designed, reviewed, and considered. The insulation materials in the current configuration are considered as non-cable secondary combustibles. The inherent safety margins included in the fire modeling methods are unchanged by this NFPA 805 Chapter 3 deviation. The selection and application of thermal insulation material is controlled per the BFN piping and equipment thermal insulation specification. TVA Fleet Procedures that govern the Plant Modifications and Engineering Change Control process are in place to review future installation impacts to the Fire Protection Program and Fire PRA, resulting in updates to the applicable analyses and calculations as required. Therefore, the safety margin inherent in the analysis for the fire event has been preserved.

3.4 Defense-in-Depth The three echelons of defense-in-depth are:

  • Prevent fires from starting (i.e., combustible/hot work controls)
  • Rapidly detect, control, and extinguish fires that do occur, thereby limiting damage (i.e., fire detection systems, automatic fire suppression, manual fire suppression, pre-fire plans)
  • Provide adequate level of fire protection for systems and structures so that a fire will not prevent essential safety functions from being performed (i.e., fire barriers, fire rated cable, success path remains free of fire damage, recovery actions)

The use of insulation material, which is more than limited combustibles does not affect Echelons 1, 2, or 3. The insulation material, and specifically the increase in heat contribution in conjunction with the limited applications, does not introduce new ignition sources, does not exceed the design bases of installed fire protection systems, does not compromise manual fire suppression functions, and does not adversely impact fire protection systems and features or post-fire safe shutdown capability as previously designed, reviewed, and considered.

Echelon 1: Prevent Fires from Starting The thermal insulation does not introduce new ignition sources and presents a negligible hazard in terms of secondary or intervening combustibles. The selection and application of thermal insulation material is controlled per the TVA insulation specification. TVA Fleet Procedures that govern the Plant Modifications and Engineering Change Control process are in place to review future installation impacts to the Fire Protection Program and Fire PRA, resulting in updates to the applicable analyses and calculations as required.

Echelon 2: Rapidly Detect, Control, and Extinguish Fires that do Occur, Thereby Limiting Damage The limited applications of exposed thermal insulation materials installed for industrial personnel safety and on miscellaneous system piping do not result in increased combustible loading which would challenge the design bases of the installed fire protection systems. The presence of the thermal insulation in limited applications and associated procedural controls do not impact the ability of the automatic suppression and detection systems to perform credited functions. Portable fire extinguishers and CNL-18-001 E1-6 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials hose stations are available for manual firefighting activities by the site fire brigade.

Therefore, if a fire were to occur, damage would be limited.

Echelon 3: Provide Adequate Level of Fire Protection for Systems and Structures so that a Fire will not Prevent Essential Safety Functions from being Performed The limited applications of exposed thermal insulation materials installed for industrial personnel safety and on miscellaneous system piping do not adversely impact the installed fire protection systems and features, and essential safety functions are maintained and capable of being performed. The insulation material does not compromise post-fire safe shutdown capability as previously designed, reviewed, and considered. The insulation materials in the current configuration are considered as non-cable secondary combustibles and are bound by the Fire PRA. TVA Fleet Procedures that govern the Plant Modifications and Engineering Change Control process are in place to review future installation impacts to the Fire Protection Program and Fire PRA, resulting in updates to the applicable analyses and calculations as required. The presence of the thermal insulation does not compromise automatic/manual fire protection functions, or post-fire safe shutdown capability and will not prevent essential safety functions from being performed.

3.5 Future Installations Future installations of insulation materials are controlled by the Plant Modifications and Engineering Change Control process, which requires the performance of an NFPA 805 Fire Protection Program Change Impact Screening. This process includes a screening requirement for insulation material to be noncombustible or limited combustible material.

Insulation materials that do not meet this screening criteria require a Fire Protection Program Change Evaluation.

3.6 Conclusion The use of thermal insulation materials that do not meet the limited combustible criteria of NFPA 805 has been previously approved and the basis for the previous approval remains valid. TVA has determined that the approach satisfies the following criteria:

  • The performance goals, performance objectives, and performance criteria specified in NFPA 805 related to nuclear safety and radiological release
  • Maintains safety margin
  • Maintains fire protection defense-in-depth (i.e., fire prevention, fire detection, fire suppression, mitigation, and post-fire safe shutdown capability)

Therefore, TVA requests that the previously approved insulation materials continue to be permitted. The correction of the error in Reference 1, Attachment A, Item 3.3.4, Insulation Materials, does not adversely affect NFPA 805 evaluations.

This requested change corrects the erroneous compliance statement in Reference 1, Transition Report, Attachment A, Table B-1, Item 3.3.4 Insulation Materials, with the correct compliance statement.

The change to the BFN RFOLs are administrative in nature. The proposed change does not result in any physical changes in the plants or in any plant equipment nor in any changes to CNL-18-001 E1-7 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials BFN NFPA 805 program procedures. No changes will be made to any of the previously evaluated NFPA 805 program modifications previously approved by NRC.

4.0 Regulatory Evaluation 4.1 Applicable Regulatory Requirements/Criteria On July 16, 2004, the NRC amended 10 CFR 50.48, Fire Protection, to add a new subsection, 10 CFR 50.48(c), which establishes alternative fire protection requirements. 10 CFR 50.48 endorses, with exceptions, NFPA 805, Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants - 2001 Edition (NFPA 805) (Reference 4) as a voluntary alternative for demonstrating compliance with 10 CFR 50.48 Section (b), Appendix R, and Section (f), Decommissioning.

The voluntary adoption of 10 CFR 50.48(c) by BFN does not eliminate the need to comply with 10 CFR 50.48(a) and to CFR 50, Appendix A, GDC 3, Fire Protection.

The new rule provides actions that may be taken to establish compliance with 10 CFR 50.48(a),

which requires each operating nuclear power plant to have a fire protection program plan that satisfies GDC 3, as well as specific requirements in that section. The transition process described in 10 CFR 50.48(c)(3)(ii) provides, in pertinent parts, that a licensee intending to adopt the new rule must, among other things, "modify the fire protection plan required by paragraph (a) of that section to reflect the licensee's decision to comply with NFPA 805."

Therefore, to the extent that the contents of the existing fire protection program plan required by 10 CFR 50.48(a) are inconsistent with NFPA 805, the fire protection program plan must be modified to achieve compliance with the requirements in NFPA 805. All other requirements of 10 CFR 50.48(a) and GDC 3 have corresponding requirements in NFPA 805.

4.2 Precedents Similar requests for performance-based methods have been included in other LARs to transition to fire protection licensing basis under NFPA 805. Examples include:

  • On February 3, 2017, the NRC issued Amendment No. 249 to the H. B.

Robinson Renewed Facility Operating License (Reference 8). The amendment authorized the transition of the fire protection program to a risk-informed, performance-based program based on NFPA 805. Section 3.1.4.5 of the NRC Safety Evaluation discussed H. B. Robinsons use of insulation materials that did not meet NFPA 805 Section 1.6.36 definition of non-combustible materials.

NRC evaluated these existing similar insulation materials and concluded it was an acceptable alternative.

  • On September 26, 2013, Duke Energy submitted a LAR (Reference 9) for the McGuire Nuclear Station Units 1 and 2, to transition the fire protection program to a riskinformed, performance-based program based on NFPA Standard 805.

By letter dated September 29, 2016 (Reference 10), Duke Energy submitted a response to a request for additional information for similar insulation material concerns and compliance with NFPA 805, Section 3.3.4, Insulation Materials.

On December 6, 2016, the NRC issued Amendment Nos. 291 and 270 to the Renewed Facility Operating License for McGuire Nuclear Station, Units 1 and 2, respectively (Reference 11), authorizing the transition of the fire protection CNL-18-001 E1-8 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials program to a risk-informed, performance-based program based on NFPA Standard 805.

4.3 No Significant Hazards Consideration Determination TVA requests an amendment to the Browns Ferry Nuclear (BFN) Plant Renewed Facility Operating License (RFOL), paragraphs 2.C.(13), 2.C.(14), and 2.C.(7) for BFN Units 1, 2, and 3, respectively, to update the licenses to document the correction of an error in Reference 1, Transition Report, Attachment A, Table B-1 Item 3.4.4, Insulation Materials.

The proposed change also provides a corrected entry to the Compliance statement from Complies to Complies with previous approval. This proposed revision corrects erroneous information provided in the BFN Transition Report [Letter from TVA to NRC, "License Amendment Request to Adopt NFPA 805 Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants (2001 Edition), (Technical Specification Change TS-480)," dated March 27, 2013 (ML13092A393)] in support of the BFN implementation of NFPA 805, Performance Based Standard for Fire Protection for Light Water Reactor Generating Plants at BFN.

A written evaluation of the significant hazards consideration of a proposed license amendment is required by 10 CFR 50.92. According to 10 CFR 50.92, a proposed amendment to an operating license involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not:

  • Involve a significant increase in the probability or consequences of an accident previously evaluated; or
  • Create the possibility of a new or different kind of accident from any accident previously evaluated; or
  • Involve a significant reduction in a margin of safety.

As required by 10 CFR 50.91(a), the TVA analysis of the issue of no significant hazards consideration using the standards in 10 CFR 50.92 is presented below.

1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No The proposed amendment adds the reference to this letter to the BFN RFOL License Condition paragraphs 2.C.(13), 2.C.(14), and 2.C.(7) for BFN Units 1, 2, and 3, respectively.

The change encompassed by the proposed amendment is to correct the entry in Attachment A Table B-1 of the BFN Transition Report.

The proposed change does not adversely affect accident initiators or precursors nor alter the design assumptions, conditions, and configuration of the facility or the manner in which the plant is operated and maintained. The proposed change does not affect the ability of structures, systems and components (SSCs) to perform their intended safety function to mitigate the consequences of an initiating event within the assumed acceptance limits.

Therefore, these proposed changes do not involve a significant increase in the probability of consequences of an accident previously identified.

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials

2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No The proposed amendment adds the reference to this letter to the BFN RFOL License Condition paragraphs 2.C.(13), 2.C.(14), and 2.C.(7) for BFN Units 1, 2, and 3, respectively.

The change encompassed by the proposed amendment is to correct the entry in Attachment A Table B-1 of the BFN Transition Report.

There is no risk impact to Core Damage Frequency (CDF) or Large Early Release Frequency (LERF) because this is an administrative change. Plant secondary combustibles, including insulating materials, are considered in the fire modeling input to the Fire PRA.

The proposed change does not result in any new or different kinds of accident from that previously evaluated because it does not change any precursors or equipment that is previously credited for accident mitigation.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

3. Does the proposed amendment involve a significant reduction in a margin of safety?

Response: No The proposed amendment adds the reference to this letter to the BFN RFOL License Condition paragraphs 2.C.(13), 2.C.(14), and 2.C.(7) for BFN Units 1, 2, and 3, respectively.

The change encompassed by the proposed amendment are to correct the entry in Attachment A Table B-1 of the BFN Transition Report.

This proposed change corrects erroneous information to previously approved information in the BFN Transition Report. This proposed change will have an insignificant impact on the accident analysis as it is a clarifying or administrative change. Plant secondary combustibles, including insulating materials, are considered in the fire modeling input to the Fire PRA.

The proposed change will not result in any new or different kinds of accident from that previously evaluated because it does not change any precursors or equipment that is previously credited for accident mitigation.

Therefore, based on the above discussion, these proposed changes do not involve a reduction in the margin of safety.

Based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public. TVA has evaluated the proposed amendment and determined that it involves no significant hazards consideration.

CNL-18-001 E1-10 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials 4.4 Conclusions Based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

5.0 Environmental Considerations TVA has evaluated the proposed amendment and determined that the amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

In accordance with the provisions of Title 10 of the Code of Federal Regulations (10 CFR) 50.90, Tennessee Valley Authority (TVA) requests an amendment to the Renewed Facility Operating License Nos. DPR-33, DPR-52, and DPR-68 for Browns Ferry Nuclear Plant (BFN),

Units 1, 2, and 3, respectively.

U.S. Nuclear Regulatory Commission CNL-18-001 Page 2 May 3, 2018 The proposed amendment modifies the BFN licensing basis regarding the National Fire Protection Association (NFPA) 805 program to provide a correction to previously submitted information.

Reference 1 provided TVAs Fire Protection Report that described BFNs conformance to Appendix R fire protection requirements. Reference 2 provided NRCs approval of TVAs Fire Protection Report. These references included a discussion of the insulating materials that were acceptable for use at BFN.

In Reference 3, TVA submitted a license amendment request (LAR) to adopt NFPA 805 requirements. Reference 4 provided NRCs acceptance of TVAs NFPA 805 fire protection program. In Reference 3, TVA utilized NEI 04-02 guidelines that included Attachment A, Table B-1 Transition of Fundamental Fire Protection Program & Design Elements. In Attachment A, Table B-1, Item 3.3.4, Insulation Materials, was reported as Complies with the NFPA 805 requirements.

TVA requests that the compliance statement be revised to state "Complies with previous approval." This correction is based on the previous NRC approval (Reference 2) for the use of insulating materials that are not currently approved for use with the requirements specified in NFPA 805.

Through information sharing between industry peers, TVA was informed that the definition used in NFPA 805 for Limited Combustibility (Section 3.3.4) was different from that in BTP CMEB 9.5-1. Upon review of the NFPA 805 application, TVA discovered that a discrepancy existed in the NFPA 805 LAR. In Table B-1, Item 3.3.4,"Insulation Materials," TVA reported that BFN "complies" with the NFPA 805 based on the use of noncombustible materials. However, TVA specifications allow the use of materials that are combustible and that may also not meet the NFPA 805 definition of limited combustible. This condition was entered into TVA's Corrective Action Program for tracking and closure purposes. provides the description and evaluation of the requested change. In order to correct the erroneous information in Table B-1, TVA has provided a corrected page with updated information as shown in Enclosure 2. provides a markup of the revised BFN NFPA 805 submittal Appendix A page. provides a clean typed version of the BFN NFPA 805 submittal Appendix A page. provides a markup of the affected pages of the BFN Units 1, 2, and 3 Renewed Operating Licenses. Enclosure 5 provides clean typed pages of the affected pages of the BFN Units 1, 2, and 3 Renewed Operating Licenses.

TVA has determined that there are no significant hazards consideration associated with the proposed change and that the change to the Renewed Operating License qualifies for a categorical exclusion from environmental review pursuant to the provisions of 10 CFR 51.22(c)(9).

U.S. Nuclear Regulatory Commission CNL-18-001 Page 3 May 3, 2018 The BFN Plant Operations Review Committee has reviewed this amendment request and concluded that operation of BFN in accordance with the proposed change will not endanger the health and safety of the public.

Additionally, in accordance with 10 CFR 50.91 (b)(1 ), TVA is sending a copy of this letter and enclosures, to the Alabama State Department of Public Health.

TVA requests NRC approval of this LAR by May 3, 2019 in order to support the implementation of the NFPA 805 program at BFN.

There are no new regulatory commitments contained in this submittal. Please address any questions regarding thi.s submittal to Edward D. Schrull at (423) 751-3850.

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials 1.0 Summary Description This evaluation supports a request to revise Renewed Facility Operating Licenses (RFOL)

DPR-33, DPR-52, and DPR-68 for Browns Ferry Nuclear Plant (BFN) Units 1, 2, and 3, respectively. The Enclosure to the BFN NFPA License Amendment Request (Reference 1) contained Attachment A, NEI 04-02 Attachment A, Table B-1 Transition of Fundamental Fire Protection Program & Design Elements, Item 3.3.4, Insulation Materials. This item was previously reported as it Complies with the NFPA 805 requirements. These revisions are discussed in Section 2.2 below.

The compliance statement for Item 3.3.4, Insulation Materials, is revised to state, Complies with previous approval. This correction is based on previous NRC approval (Reference 3) for the use of plastics, including insulation, shielding and sound proofing materials, that do not meet the NFPA 805 limited combustible definition. The enclosed discussion shows that the basis for the previous approval is maintained and that the modeling and evaluation of the combustible hazards of these materials continues to provide the proper consideration in the Fire Hazard Analysis for the NFPA 805 licensing basis. This proposed revision markup and clean typed copy are shown in Enclosures 2 and 3 respectively.

2.0 Detailed Description 2.1 Proposed Changes TVA requests that the response to the BFN NFPA Attachment A, Table B-1 Item 3.3.4, Insulation Materials, be revised from complies to Complies with previous approval. A markup and clean copy of the proposed change is provided in Enclosures 2 and 3 respectively.

CNL-18-001 E1-3 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials 2.2 Reason for the Proposed Change Through information sharing between industry peers, TVA was informed that the definition used in NFPA 805 for Limited Combustibility (Section 3.3.4) was different from that in CMEB-BTP 9.5.1. Upon review of the NFPA 805 application, TVA discovered that a discrepancy existed in the NFPA 805 LAR. In Table B-1, Item 3.3.4,Insulation Materials, TVA reported that BFN "complies" with the NFPA 805 strategies for use of noncombustible materials. However, NRC had previously approved BFN for the current use of insulating materials in Reference 3 for Appendix R requirements.

In order to make the Section 3.3.4, Table B-1 entry accurate, TVA requests a revision to the entry to state, Complies with previous approval. This condition is considered to be an isolated situation limited to this entry.

3.0 Technical Evaluation 3.1 Technical Basis for the Request The current NFPA 805 requirements (Reference 4) do not allow the use of some of the previously approved elastomeric insulation materials because they would exceed the 3,500 BTU/lb requirement. TVA submitted the BFN Fire Protection Report and a comparison of the BFN Fire Protection Program to NRC Branch Technical Position (BTP) CMEB 9.5-1 in Reference 2 that included a discussion of plastic, insulation, and flame retardant materials. In to Reference 2, TVA provided a comparison of the BFN Fire Protection Program to BTP CMEB 9.5-1 (Reference 5). In response to NRC Guideline C.5.d(3), Control of Combustibles, TVA provided the following response:

(3) The use of plastic materials inside buildings is controlled by the Fire Protection Plan, Section 7.2 (Reference 1). Plastic materials used at BFN include pipe insulation (Foam Plastic), cable insulation (PVC etc.), light covers etc. The combustible hazards of these materials have been considered in the Fire Hazards Analysis.

NRC approval of the BFN Fire Protection Report was provided in NRC Safety Evaluation Report (SER) (Reference 3). Section 2.9, Control of Combustibles, of the SER states; Based on the licensees submittal, the staff concluded that combustibles have been separated from safety-related systems or provided with suppression in accordance with the guidelines of BTP CMEB 9.5-1, Section C.5.d, and such separation, therefore, is acceptable.

Section 2.9 of the SER did not specifically address BFNs control of plastic materials, but the SER concluded in Section 3.0; The licensees Fire Protection Plan and Fire Hazard Analysis described in BFN-FPR was reviewed and found acceptable.

The technical basis of the original approval remains valid in that under 10 CFR 50 Appendix R, BFN controlled the use of plastic materials by the Fire Protection Plan (i.e., Appendix R Fire Protection Report, Section 7.2). BFN maintained consideration for combustible thermal insulation materials in the Appendix R Fire Hazard Analysis per the evaluations in the Combustible Load Table calculation.

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials Under the NFPA 805 licensing basis, combustible materials added by plant modifications are controlled by the NFPA 805 Fire Protection Program Change Impact Screening Process procedure whereby combustible materials including combustible thermal insulation are considered for impact to the NFPA 805 Fire Protection Program. Secondary combustibles such as foam insulation (e.g., cellular elastomeric) are considered in the Fire Hazard Analysis by fire scenario development (i.e., fire modeling) and fire risk evaluations. Secondary combustibles, such as combustible thermal insulation, are considered in the fire scenario development by the use of an increased heat release rate and zone of influence (ZOI) where appropriate for the fire scenarios affected by the secondary combustibles. The increased ZOI and resulting Fire PRA target damage are reflected in the performance-based, risk-informed fire risk evaluations. This modeling and evaluation of the combustible hazards of these materials continues to provide the proper consideration in the Fire Hazard Analysis for the NFPA 805 licensing basis. Therefore, BFN continues to meet the basis for the previous approval.

3.2 Nuclear Safety and Radiological Release Performance Criteria The selection and application of thermal insulation material is controlled per the TVA General Specification G-82, Installation, Modification and Maintenance of Insulation and Site Specification N1M-001 Installation, Modification, and Maintenance of Thermal and Antisweat Insulation. The Fire PRA development requires the inclusion of the effect of intervening or secondary combustibles to be documented and included in the analysis where determined to have fire effects as part of the performancebased approach. TVA Fleet Procedures that govern the Engineering Change Process are in place to review future installation impacts to the Fire Protection Program and Fire PRA, resulting in updates to the applicable analyses and calculations as required.

Secondary combustibles with the potential to affect the Fire PRA are considered in the fire scenario development performed in fire modeling. The supporting analyses and existing fire scenarios either (1) already consider the thermal insulation as a secondary combustible, (2) use bounding conservative target sets (i.e., expanded ZOIs due to the ignition of secondary combustibles in the area would not fail additional Fire PRA targets), or (3) the thermal insulation is out of the ZOI of any nearby fixed or transient ignition sources.

The use of insulation material other than non-combustible and more than limited combustible has no impact on the radiological release performance criteria. The radiological release review was performed based on the manual fire suppression activities in areas containing or potentially containing radioactive materials and is not dependent on the type of thermal insulation material.

The insulation material, regardless of heat contribution value, does not change the radiological release evaluation performed that concluded that potentially contaminated water is contained and smoke is monitored. The insulation materials do not add radiological materials to the area or challenge system boundaries.

CNL-18-001 E1-5 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials 3.3 Safety Margin The insulation material, and specifically the increase in heat contribution in conjunction with the limited applications, does not compromise automatic fire suppression functions, manual fire suppression functions, or post-fire safe shutdown capability as previously designed, reviewed, and considered. The insulation materials in the current configuration are considered as non-cable secondary combustibles. The inherent safety margins included in the fire modeling methods are unchanged by this NFPA 805 Chapter 3 deviation. The selection and application of thermal insulation material is controlled per the BFN piping and equipment thermal insulation specification. TVA Fleet Procedures that govern the Plant Modifications and Engineering Change Control process are in place to review future installation impacts to the Fire Protection Program and Fire PRA, resulting in updates to the applicable analyses and calculations as required. Therefore, the safety margin inherent in the analysis for the fire event has been preserved.

3.4 Defense-in-Depth The three echelons of defense-in-depth are:

  • Prevent fires from starting (i.e., combustible/hot work controls)
  • Rapidly detect, control, and extinguish fires that do occur, thereby limiting damage (i.e., fire detection systems, automatic fire suppression, manual fire suppression, pre-fire plans)
  • Provide adequate level of fire protection for systems and structures so that a fire will not prevent essential safety functions from being performed (i.e., fire barriers, fire rated cable, success path remains free of fire damage, recovery actions)

The use of insulation material, which is more than limited combustibles does not affect Echelons 1, 2, or 3. The insulation material, and specifically the increase in heat contribution in conjunction with the limited applications, does not introduce new ignition sources, does not exceed the design bases of installed fire protection systems, does not compromise manual fire suppression functions, and does not adversely impact fire protection systems and features or post-fire safe shutdown capability as previously designed, reviewed, and considered.

Echelon 1: Prevent Fires from Starting The thermal insulation does not introduce new ignition sources and presents a negligible hazard in terms of secondary or intervening combustibles. The selection and application of thermal insulation material is controlled per the TVA insulation specification. TVA Fleet Procedures that govern the Plant Modifications and Engineering Change Control process are in place to review future installation impacts to the Fire Protection Program and Fire PRA, resulting in updates to the applicable analyses and calculations as required.

Echelon 2: Rapidly Detect, Control, and Extinguish Fires that do Occur, Thereby Limiting Damage The limited applications of exposed thermal insulation materials installed for industrial personnel safety and on miscellaneous system piping do not result in increased combustible loading which would challenge the design bases of the installed fire protection systems. The presence of the thermal insulation in limited applications and associated procedural controls do not impact the ability of the automatic suppression and detection systems to perform credited functions. Portable fire extinguishers and CNL-18-001 E1-6 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials hose stations are available for manual firefighting activities by the site fire brigade.

Therefore, if a fire were to occur, damage would be limited.

Echelon 3: Provide Adequate Level of Fire Protection for Systems and Structures so that a Fire will not Prevent Essential Safety Functions from being Performed The limited applications of exposed thermal insulation materials installed for industrial personnel safety and on miscellaneous system piping do not adversely impact the installed fire protection systems and features, and essential safety functions are maintained and capable of being performed. The insulation material does not compromise post-fire safe shutdown capability as previously designed, reviewed, and considered. The insulation materials in the current configuration are considered as non-cable secondary combustibles and are bound by the Fire PRA. TVA Fleet Procedures that govern the Plant Modifications and Engineering Change Control process are in place to review future installation impacts to the Fire Protection Program and Fire PRA, resulting in updates to the applicable analyses and calculations as required. The presence of the thermal insulation does not compromise automatic/manual fire protection functions, or post-fire safe shutdown capability and will not prevent essential safety functions from being performed.

3.5 Future Installations Future installations of insulation materials are controlled by the Plant Modifications and Engineering Change Control process, which requires the performance of an NFPA 805 Fire Protection Program Change Impact Screening. This process includes a screening requirement for insulation material to be noncombustible or limited combustible material.

Insulation materials that do not meet this screening criteria require a Fire Protection Program Change Evaluation.

3.6 Conclusion The use of thermal insulation materials that do not meet the limited combustible criteria of NFPA 805 has been previously approved and the basis for the previous approval remains valid. TVA has determined that the approach satisfies the following criteria:

  • The performance goals, performance objectives, and performance criteria specified in NFPA 805 related to nuclear safety and radiological release
  • Maintains safety margin
  • Maintains fire protection defense-in-depth (i.e., fire prevention, fire detection, fire suppression, mitigation, and post-fire safe shutdown capability)

Therefore, TVA requests that the previously approved insulation materials continue to be permitted. The correction of the error in Reference 1, Attachment A, Item 3.3.4, Insulation Materials, does not adversely affect NFPA 805 evaluations.

This requested change corrects the erroneous compliance statement in Reference 1, Transition Report, Attachment A, Table B-1, Item 3.3.4 Insulation Materials, with the correct compliance statement.

The change to the BFN RFOLs are administrative in nature. The proposed change does not result in any physical changes in the plants or in any plant equipment nor in any changes to CNL-18-001 E1-7 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials BFN NFPA 805 program procedures. No changes will be made to any of the previously evaluated NFPA 805 program modifications previously approved by NRC.

4.0 Regulatory Evaluation 4.1 Applicable Regulatory Requirements/Criteria On July 16, 2004, the NRC amended 10 CFR 50.48, Fire Protection, to add a new subsection, 10 CFR 50.48(c), which establishes alternative fire protection requirements. 10 CFR 50.48 endorses, with exceptions, NFPA 805, Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants - 2001 Edition (NFPA 805) (Reference 4) as a voluntary alternative for demonstrating compliance with 10 CFR 50.48 Section (b), Appendix R, and Section (f), Decommissioning.

The voluntary adoption of 10 CFR 50.48(c) by BFN does not eliminate the need to comply with 10 CFR 50.48(a) and to CFR 50, Appendix A, GDC 3, Fire Protection.

The new rule provides actions that may be taken to establish compliance with 10 CFR 50.48(a),

which requires each operating nuclear power plant to have a fire protection program plan that satisfies GDC 3, as well as specific requirements in that section. The transition process described in 10 CFR 50.48(c)(3)(ii) provides, in pertinent parts, that a licensee intending to adopt the new rule must, among other things, "modify the fire protection plan required by paragraph (a) of that section to reflect the licensee's decision to comply with NFPA 805."

Therefore, to the extent that the contents of the existing fire protection program plan required by 10 CFR 50.48(a) are inconsistent with NFPA 805, the fire protection program plan must be modified to achieve compliance with the requirements in NFPA 805. All other requirements of 10 CFR 50.48(a) and GDC 3 have corresponding requirements in NFPA 805.

4.2 Precedents Similar requests for performance-based methods have been included in other LARs to transition to fire protection licensing basis under NFPA 805. Examples include:

  • On February 3, 2017, the NRC issued Amendment No. 249 to the H. B.

Robinson Renewed Facility Operating License (Reference 8). The amendment authorized the transition of the fire protection program to a risk-informed, performance-based program based on NFPA 805. Section 3.1.4.5 of the NRC Safety Evaluation discussed H. B. Robinsons use of insulation materials that did not meet NFPA 805 Section 1.6.36 definition of non-combustible materials.

NRC evaluated these existing similar insulation materials and concluded it was an acceptable alternative.

  • On September 26, 2013, Duke Energy submitted a LAR (Reference 9) for the McGuire Nuclear Station Units 1 and 2, to transition the fire protection program to a riskinformed, performance-based program based on NFPA Standard 805.

By letter dated September 29, 2016 (Reference 10), Duke Energy submitted a response to a request for additional information for similar insulation material concerns and compliance with NFPA 805, Section 3.3.4, Insulation Materials.

On December 6, 2016, the NRC issued Amendment Nos. 291 and 270 to the Renewed Facility Operating License for McGuire Nuclear Station, Units 1 and 2, respectively (Reference 11), authorizing the transition of the fire protection CNL-18-001 E1-8 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials program to a risk-informed, performance-based program based on NFPA Standard 805.

4.3 No Significant Hazards Consideration Determination TVA requests an amendment to the Browns Ferry Nuclear (BFN) Plant Renewed Facility Operating License (RFOL), paragraphs 2.C.(13), 2.C.(14), and 2.C.(7) for BFN Units 1, 2, and 3, respectively, to update the licenses to document the correction of an error in Reference 1, Transition Report, Attachment A, Table B-1 Item 3.4.4, Insulation Materials.

The proposed change also provides a corrected entry to the Compliance statement from Complies to Complies with previous approval. This proposed revision corrects erroneous information provided in the BFN Transition Report [Letter from TVA to NRC, "License Amendment Request to Adopt NFPA 805 Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants (2001 Edition), (Technical Specification Change TS-480)," dated March 27, 2013 (ML13092A393)] in support of the BFN implementation of NFPA 805, Performance Based Standard for Fire Protection for Light Water Reactor Generating Plants at BFN.

A written evaluation of the significant hazards consideration of a proposed license amendment is required by 10 CFR 50.92. According to 10 CFR 50.92, a proposed amendment to an operating license involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not:

  • Involve a significant increase in the probability or consequences of an accident previously evaluated; or
  • Create the possibility of a new or different kind of accident from any accident previously evaluated; or
  • Involve a significant reduction in a margin of safety.

As required by 10 CFR 50.91(a), the TVA analysis of the issue of no significant hazards consideration using the standards in 10 CFR 50.92 is presented below.

1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No The proposed amendment adds the reference to this letter to the BFN RFOL License Condition paragraphs 2.C.(13), 2.C.(14), and 2.C.(7) for BFN Units 1, 2, and 3, respectively.

The change encompassed by the proposed amendment is to correct the entry in Attachment A Table B-1 of the BFN Transition Report.

The proposed change does not adversely affect accident initiators or precursors nor alter the design assumptions, conditions, and configuration of the facility or the manner in which the plant is operated and maintained. The proposed change does not affect the ability of structures, systems and components (SSCs) to perform their intended safety function to mitigate the consequences of an initiating event within the assumed acceptance limits.

Therefore, these proposed changes do not involve a significant increase in the probability of consequences of an accident previously identified.

CNL-18-001 E1-9 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials

2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No The proposed amendment adds the reference to this letter to the BFN RFOL License Condition paragraphs 2.C.(13), 2.C.(14), and 2.C.(7) for BFN Units 1, 2, and 3, respectively.

The change encompassed by the proposed amendment is to correct the entry in Attachment A Table B-1 of the BFN Transition Report.

There is no risk impact to Core Damage Frequency (CDF) or Large Early Release Frequency (LERF) because this is an administrative change. Plant secondary combustibles, including insulating materials, are considered in the fire modeling input to the Fire PRA.

The proposed change does not result in any new or different kinds of accident from that previously evaluated because it does not change any precursors or equipment that is previously credited for accident mitigation.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

3. Does the proposed amendment involve a significant reduction in a margin of safety?

Response: No The proposed amendment adds the reference to this letter to the BFN RFOL License Condition paragraphs 2.C.(13), 2.C.(14), and 2.C.(7) for BFN Units 1, 2, and 3, respectively.

The change encompassed by the proposed amendment are to correct the entry in Attachment A Table B-1 of the BFN Transition Report.

This proposed change corrects erroneous information to previously approved information in the BFN Transition Report. This proposed change will have an insignificant impact on the accident analysis as it is a clarifying or administrative change. Plant secondary combustibles, including insulating materials, are considered in the fire modeling input to the Fire PRA.

The proposed change will not result in any new or different kinds of accident from that previously evaluated because it does not change any precursors or equipment that is previously credited for accident mitigation.

Therefore, based on the above discussion, these proposed changes do not involve a reduction in the margin of safety.

Based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public. TVA has evaluated the proposed amendment and determined that it involves no significant hazards consideration.

CNL-18-001 E1-10 of 12

Enclosure 1 Request for Revision to Attachment A, Table B-1, NFPA 805 Item 3.3.4 Insulation Materials 4.4 Conclusions Based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

5.0 Environmental Considerations TVA has evaluated the proposed amendment and determined that the amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

3.3.4 Insulation Materials Under the NFPA 805 licensing basis, added combustible materials by (Continued) plant modifications are controlled by the NFPA 805 Fire Protection Program Change Impact Screening Process procedure whereby combustible materials including combustible thermal insulation are considered for impact to the NFPA 805 Fire Protection Program.

Secondary combustibles such as foam insulation are considered in the Fire Hazard Analysis by fire scenario development (i.e., fire modeling) and fire risk evaluations. Where appropriate, secondary combustibles are considered in the fire scenario development by the use of an increased heat release rate and zone of influence as applicable for the fire scenarios affected by the secondary combustibles. The increased zone of influence and resulting Fire PRA target damage are reflected in the performance-based, risk-informed fire risk evaluations. This modeling and evaluation of the combustible hazards of these materials continues to provide the proper consideration in the Fire Hazard Analysis for the NFPA 805 licensing basis. Therefore, BFN continues to meet the basis for the previous approval.

3.3.5.1 [Electrical Wiring Above 3.3.5.1 Complies Wiring above suspended ceilings is kept to a minimum by limiting the Suspended Ceiling Limitations] Wiring above suspended ceiling shall be kept to a minimum. Where wiring to only that required for the area in which the suspended ceiling is installed, electrical wiring shall be listed for plenum use, routed in armored located. Concealed spaces have limited amounts of combustibles, mainly cable, routed in metallic conduit, or routed in cable trays with solid metal cable insulation. These cables have been accounted for in the Fire top and bottom covers. Hazards Analysis (FHA).

The FHA has reviewed the total combustible loading in each fire zone /

area and has found the fire protection and suppression features adequate for the present fire hazards.

Item for Implementation:

Plant specifications do not include requirements for wiring installed above suspended ceilings. Revise Specification G-38 to specify that future wiring above suspended ceilings shall be listed for plenum use, routed in Fire Safety Analysis Data Manager (4.129) TVA Browns Ferry Page: 13.a of 55 BFN Units 1, 2, and 3 NFPA 805 Transition Report, Page 89 of 1661
