Proposed Technical Specifications Change TS-505 -Request for License Amendments

-Extended Power Uprate

Reference:

Letter from TVA to NRC, "Technical Specifications Changes TS-431 and TS-41 8 -Extended Power Uprate (EPU) -Withdrawal of Requests and Update to EPU Plans and Schedules," dated September 18, 2014 (ADAMS Accession No. MLI14265A487)

In accordance with the provisions of 10 Code of Federal Regulations (10 CFR) 50.90,"Application for amendment of license, construction permit, or early site permit," Tennessee Valley Authority (TVA) is submitting a request for a Technical Specification (TS)amendment (TS-505) to Renewed Facility Operating License Nos. DPR-33, DPR-52, and DPR-68 for Browns Ferry Nuclear Plant (BFN) Units 1, 2, and 3, respectively.

The proposed amendment will increase the authorized maximum steady-state reactor core power level for each unit from 3458 MWt to 3952 MWt. This license amendment request (LAR) represents an increase of approximately 20 percent above the original licensed thermal power (OLTP)level of 3293 MWt, and an increase of approximately 14.3 percent above the current licensed thermal power (CLTP) level of 3458 MWt.The information provided in the attachments to this letter represents a consolidation of plant-specific safety analyses as well as plant-specific confirmation of generic evaluations applicable to a boiling water reactor (BWR) constant pressure power uprate for the three BEN units.On September 8, 1998, the Nuclear Regulatory Commission (NRC) approved a stretch power uprate for BFN Units 2 and 3 to increase the authorized maximum thermal power level to 3458 MWt. By letter dated March 6, 2007, the NRC issued an amendment to the BFN Unit 1 operating license to also increase the authorized maximum thermal power level to 3458 MWt.

Proprietary Information and Critical Energy Infrastructure Information Withhold from Public Disclosure Under 10 CFR 2.390 This letter is decontrolled when separated from Attachments 6, 8 10, 12, 14, 16 18, 20, 22, 24, 26, 28, 30, 32, 34, 37, 40, and 43 In the referenced letter dated September 18, 2014, TVA withdrew previous BFN EPU LARs and provided its revised plans and schedule for the BEN EPU project. In the interim months, TVA has held several meetings with the NRC staff to provide pre-application discussions on key aspects of the EPU project, including fuel considerations, startup test plans, replacement steam dryers, flow-induced vibration, and the elimination of credit for containment accident pressure in net positive suction head (NPSH) evaluations for emergency core cooling system (EGOS) pumps. This [AR submittal is consistent with TVA's letter of September 18, 2014, which stated that a new, consolidated BEN EPU [AR would be submitted by October 2015.The enclosure to this letter provides a summary of the proposed changes to the BEN operating licenses and Technical Specifications due to EPU operation, the no significant hazards considerations, and environmental considerations.

Attachments 1 through 52 include a description of the proposed changes to the licensing basis and provide supporting documentation.

This [AR is subdivided as follows: Attachment 1 List of Regulatory Commitments There are no commitments associated with this [AR. Those actions associated with the amendment approval will be complete prior to implementation of EPU, except where those actions require an increase in power above the currently licensed power level. In those instances, defined actions will be completed during power ascension and will be incorporated into license conditions (see Attachments 2 and 3).Attachment 2 Proposed Technical Specification Changes (Markups)Attachment 2 provides a markup of the affected operating license and Technical Specifications pages indicating the proposed changes for EPU.Attachment 3 Retyped Proposed Technical Specification Changes Attachment 3 provides a camera-ready retype of the affected Technical Specification pages with changes incorporated.

Attachment 4 Proposed Technical Specification Bases Changes (Markups)Attachment 4 provides a markup of the affected Technical Specification Bases pages indicating the proposed changes for EPU.Attachment 5 Retyped Proposed Technical Specification Bases Changes Attachment 5 provides a camera-ready retype of the affected Technical Specification Bases pages with changes incorporated.

The analysis demonstrates that BEN will continue to meet GDC-17 requirements while operating'at EPU conditions, and the offsite power system has the capacity and capability to supply power to safety loads and required equipment.

Because Attachment 43 contains critical energy infrastructure information that is considered sensitive, unclassified (non-safeguard) information, TVA requests that it be withheld from public disclosure in accordance with the provisions of 10 CFR 2.390(d)(1).

Attachment 44 Probabilistic Risk Assessment Attachment 44 provides the results of the assessment of the effect of EPU on risk as characterized as a change in the core damage frequency (CDF) and large early release frequency (LERF). In assessing these changes, TVA followed the guidelines of Regulatory Guide 1.174, An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis, to determine the resultant risk acceptance region.Attachment 45 Flow Induced Vibration Analysis and Monitoring Program Attachment 44 provides a detailed discussion of the analyses and testing program undertaken to provide assurance that unacceptable flow induced vibration issues are not experienced at BEN due to EPU implementation for affected piping systems.Attachment 46 Startup Test Plan Attachment 46 describes the testing TVA will perform following the EPU implementation outages at BFN Units 1, 2, and 3 (i.e., refueling outages scheduled for Spring 2018, Fall 2018, and Spring 2019 for Units 3, 1, and 2, respectively).

Following each of these outages, TVA will conduct a comprehensive EPU startup test program to ensure the safe operation of each plant. Attachment 46 describes the test program.

Subject:

Proposed Technical Specifications Change TS-505 -Request for License Amendments

-Extended Power Uprate

Reference:

Letter from TVA to NRC, "Technical Specifications Changes TS-431 and TS-41 8 -Extended Power Uprate (EPU) -Withdrawal of Requests and Update to EPU Plans and Schedules," dated September 18, 2014 (ADAMS Accession No. MLI14265A487)

In accordance with the provisions of 10 Code of Federal Regulations (10 CFR) 50.90,"Application for amendment of license, construction permit, or early site permit," Tennessee Valley Authority (TVA) is submitting a request for a Technical Specification (TS)amendment (TS-505) to Renewed Facility Operating License Nos. DPR-33, DPR-52, and DPR-68 for Browns Ferry Nuclear Plant (BFN) Units 1, 2, and 3, respectively.

The proposed amendment will increase the authorized maximum steady-state reactor core power level for each unit from 3458 MWt to 3952 MWt. This license amendment request (LAR) represents an increase of approximately 20 percent above the original licensed thermal power (OLTP)level of 3293 MWt, and an increase of approximately 14.3 percent above the current licensed thermal power (CLTP) level of 3458 MWt.The information provided in the attachments to this letter represents a consolidation of plant-specific safety analyses as well as plant-specific confirmation of generic evaluations applicable to a boiling water reactor (BWR) constant pressure power uprate for the three BEN units.On September 8, 1998, the Nuclear Regulatory Commission (NRC) approved a stretch power uprate for BFN Units 2 and 3 to increase the authorized maximum thermal power level to 3458 MWt. By letter dated March 6, 2007, the NRC issued an amendment to the BFN Unit 1 operating license to also increase the authorized maximum thermal power level to 3458 MWt.

Proprietary Information and Critical Energy Infrastructure Information Withhold from Public Disclosure Under 10 CFR 2.390 This letter is decontrolled when separated from Attachments 6, 8 10, 12, 14, 16 18, 20, 22, 24, 26, 28, 30, 32, 34, 37, 40, and 43 In the referenced letter dated September 18, 2014, TVA withdrew previous BFN EPU LARs and provided its revised plans and schedule for the BEN EPU project. In the interim months, TVA has held several meetings with the NRC staff to provide pre-application discussions on key aspects of the EPU project, including fuel considerations, startup test plans, replacement steam dryers, flow-induced vibration, and the elimination of credit for containment accident pressure in net positive suction head (NPSH) evaluations for emergency core cooling system (EGOS) pumps. This [AR submittal is consistent with TVA's letter of September 18, 2014, which stated that a new, consolidated BEN EPU [AR would be submitted by October 2015.The enclosure to this letter provides a summary of the proposed changes to the BEN operating licenses and Technical Specifications due to EPU operation, the no significant hazards considerations, and environmental considerations.

Attachments 1 through 52 include a description of the proposed changes to the licensing basis and provide supporting documentation.

This [AR is subdivided as follows: Attachment 1 List of Regulatory Commitments There are no commitments associated with this [AR. Those actions associated with the amendment approval will be complete prior to implementation of EPU, except where those actions require an increase in power above the currently licensed power level. In those instances, defined actions will be completed during power ascension and will be incorporated into license conditions (see Attachments 2 and 3).Attachment 2 Proposed Technical Specification Changes (Markups)Attachment 2 provides a markup of the affected operating license and Technical Specifications pages indicating the proposed changes for EPU.Attachment 3 Retyped Proposed Technical Specification Changes Attachment 3 provides a camera-ready retype of the affected Technical Specification pages with changes incorporated.

Attachment 4 Proposed Technical Specification Bases Changes (Markups)Attachment 4 provides a markup of the affected Technical Specification Bases pages indicating the proposed changes for EPU.Attachment 5 Retyped Proposed Technical Specification Bases Changes Attachment 5 provides a camera-ready retype of the affected Technical Specification Bases pages with changes incorporated.

U. S. Nuclear Regulatory Commission CNL-1 5-1 69 Page 3 September 21, 2015 Attachment 6 NEDC-33860P, Safety Analysis Report for Browns Ferry Nuclear Plant Units 1, 2, and 3 Extended Power Uprate (proprietary)

Attachment 6 provides a proprietary version of the GE-Hitachi Nuclear Energy Americas LLC (GEH) Power Uprate Safety Analysis Report (PUSAR), NEDC-33860P, Safety Analysis Report for Browns Ferry Nuclear Plant Units 1, 2, and 3 Extended Power Uprate. This report summarizes the results of safety analyses and evaluations performed that support the proposed increase in the authorized maximum steady-state reactor core power level.The PUSAR technical evaluations supporting the proposed EPU are based on NRC-approved licensing topical report, NEDC-33304P-A, Constant Pressure Power Uprate, Revision 4 (referred to as the Constant Pressure Power Uprate Licensing Topical Report (CLTR)). For topics outside the CLTR approved applicability (e.g., use of AREVA ATRIUM 10XM fuel), the technical evaluations are based on a series of NRC-approved AREVA methods. The content of the technical evaluations is consistent with the guidance provided in NRC Review Standard RS-001, Review Standard for Extended Power Uprates, Revision 0, dated December 2003, as it applies to the licensing basis of BFN Units 1, 2, and 3.Certain information provided in Attachment 6 is considered proprietary information by the Electric Power Research Institute (EPRI). EPRI and GEH separately consider portions of the information provided in Attachment 6 of this LAR to be proprietary and, therefore, exempt from public disclosure pursuant to 10 CFR 2.390. Affidavits for withholding information, executed by GEH and EPRI, are provided in Attachment 50 and Attachment 52, respectively.

A non-proprietary version of the document is provided in Attachment

7. Therefore, on behalf of GEH and EPRI, TVA requests that Attachment 6 be withheld from public disclosure in accordance with the GEH and EPRI affidavits and the provisions of 10 CFR 2.390.Attachment 7 NEDO-33860, Safety Analysis Report for Browns Ferry Nuclear Plant Units 1, 2, and 3 Extended Power Uprate (non-proprietary)

Attachment 8 ANP-3403P, Fuel Uprate Safety Analysis Report for Browns Ferry Units 1, 2, and 3 (proprietary)

Attachment 8 provides a proprietary version of the AREVA Inc.(AREVA) Fuel Uprate Safety Analysis Report (FUSAR), ANP-'3403P, 'Fuel Uprate Safety Analysis Report for Browns Ferry Units 1, 2, and 3." This report supplements the PUSAR and summarizes the results of fuel-related safety analyses and evaluations performed that support the proposed increase in the authorized maximum steady-state reactor core power level.

U. S. Nuclear Regulatory Commission CNL-1 5-1 69 Page 4 September 21, 2015 The FUSAR technical evaluations supporting the proposed EPU are based on a series of NRC-approved AREVA methods that are summarized in LAR Attachment

36. The safety evaluations documented in Attachment 8 are based on the continued use of AREVA's ATRIUM 10XM fuel design. Where appropriate, evaluations for the existing ATRIUM-10 fuel design have also been included because the potential exists that some fuel of this type may still be resident in a BFN reactor core upon implementation of EPU..The general format of the technical evaluations in Attachment 8 is consistent with the guidance provided in NRC Review Standard RS-001, as it applies to the licensing basis of BFN Units 1, 2, and 3. However, because only selected portions of RS-001 are addressed, the numbering of individual sections is discontinuous.

AREVA considers portions of the information provided in Attachment 8 of this LAR to be proprietary and, therefore, exempt from public disclosure pursuant to 10 CFR 2.390. An affidavit for withholding information, executed by AREVA, is provided in Attachment

51. A non-proprietary version of the document is provided in Attachment
9. Therefore, on behalf of AREVA, TVA requests that Attachment 8 be withheld from public disclosure in accordance with the AREVA affidavit and the provisions of 10 CFR 2.390.Attachment 9 ANP-3403NP, Fuel Uprate Safety Analysis Report for Browns Ferry Units 1, 2, and 3 (non-proprietary)

Attachment 10 ANP-3377P, Browns Ferry Units 1, 2, and 3 LOCA Break Spectrum Analysis for ATRIUM 10XM Fuel (EPU) (proprietary)

Attachment 10 provides the results of a loss-of-coolant accident (LOCA) break spectrum analysis for BFN Units 1, 2, and 3. The break spectrum analysis is used to identify the parameters that result in the highest calculated peak Cladding temperature (POT)during a postulated LOCA.AREVA considers portions of the info~rmation provided in Attachment 10 of this LAR to be proprietary and, therefore, exempt from public disclosure pursuant to 10 CFR 2.390. An affidavit for withholding information, executed by AREVA, is provided in Attachment

51. A non-proprietary version of the document is provided in Attachment
11. Therefore, on behalf of AREVA, TVA requests that Attachment 10 be withheld from public disclosure in accordance with the AREVA affidavit and the provisions of 10 CFR 2.390.

U. S. Nuciear Regulatory Commission CNL-1 5-169 Page 13 September 21, 2015 Attachment 43 Transmission System Stability Evaluation Attachment 43 provides the results of the BFN transmission system stability evaluation.

This study evaluated the impact of BEN operation at EPU conditions with respect to continued compliance with 10 CFR Part 50, Appendix A, General Design Criterion (GDC)-17, Electric Power Systems. The study assumed three unit operation at a maximum power output of 1,318 MWe (each unit)based on a heat balance calculation (optimum main condenser vacuum).Attachment 43 documents load flow analysis of the offsite power supply considering various pre-event outages and a subsequent plant design basis event LOCA. The analysis demonstrates that BEN will continue to meet GDC-17 requirements while operating'at EPU conditions, and the offsite power system has the capacity and capability to supply power to safety loads and required equipment.

Because Attachment 43 contains critical energy infrastructure information that is considered sensitive, unclassified (non-safeguard) information, TVA requests that it be withheld from public disclosure in accordance with the provisions of 10 CFR 2.390(d)(1).
