The proposed amendment would increase the authorized maximum steady-state reactor core power level for each unit from 3,458 megawatt thermal (MWt) to 3,952 MWt. This LAR represents an increase of approximately 20 percent above the original licensed thermal power level of 3,293 MWt, and an increase of approximately 14.3 percent above the current licensed thermal power level of 3,458 MWt. To support its safety evaluations, the Nuclear Regulatory Commission staff will conduct an audit at the EXCEL Services Corporation facility in Rockville, Maryland, from April 19 to 21, 2016. The audit plan to support the review of the extended power uprate (EPU) LAR regarding the structural adequacy of the steam dryer is enclosed.

By letter dated September 21, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML 15282A 152), as supplemented by letters dated November 13, December 15, and December 18, 2015 (ADAMS Accession Nos.

The proposed amendment would increase the authorized maximum steady-state reactor core power level for each unit from 3,458 megawatt thermal (MWt) to 3,952 MWt. This LAR represents an increase of approximately 20 percent above the original licensed thermal power level of 3,293 MWt, and an increase of approximately 14.3 percent above the current licensed thermal power level of 3,458 MWt. The NRC staff has determined that a regulatory audit of the BFN LAR should be conducted in accordance with the Nuclear Reactor Regulation (NRR) Office Instruction LIC-111, "Regulatory Audits," for the NRC staff to gain a better understanding of the licensee's calculations and other aspects of the LAR. Regulatory Audit Basis The basis of this audit is TVA's LAR and NUREG-0800, "Standard Review Plan for the Review of Nuclear Power Plants: Section 3.9.2, "Dynamic Testing and Analysis of Systems, Structures and Components," Section 3.9.1, "Special Topics for Mechanical components," Section 3.9.3, "ASME Code Class 1, 2, and 3 Components, and Component Supports, and Core Support Structures," and Section 3.9.5, "Reactor Pressure Vessel Internals." This audit will provide information necessary to complete the NRC staff's evaluation of the proposed extended power uprate (EPU) LAR for the NRR Mechanical Engineering Branch (EMCB). Enclosure
