Ladies and Gentlemen:

By letter dated September 6, 2016 (i.e., Reference 1 ), Duke Energy Progress, LLC (Duke Energy) submitted a license amendment request (LAR) for the Brunswick Steam Electric Plant (BSEP), Unit Nos. 1 and 2, to support an expansion of the core power-flow operating range (i.e., Maximum Extended Load Line Limit Analysis Plus (MELLLA+)).

Subsequently, the NRC initiated an audit (i.e., Reference

2) to support their review of the LAR by conducting confirmatory calculations using the TRACE computer code. Prior to issuance of the NRC audit plan, a telephone call was held on September 20, 2016, to discuss the feasibility of Duke Energy providing certain BSEP core-modelling information to support NRC development of a TRACE computer model. The NRC stated that development of this computer model was not required for the BSEP MELLLA+ license amendment request review, and as a result, would be separate from and not be billable as a MELLLA+ license amendment request review activity.

During the call, Duke Energy identified two items that could be used to support the NRC's model development efforts. The first item is AREVA NP (AREVA) Document Number 51-9173927-000, ATRIUMŽ 10XM Data for Brunswick MELLLA+ LAR Support. The second item is a copy of the General Electric Hitachi (GEH) TRAC-G computer code base deck that supports the BSEP MELLLA+ license amendment request, and the associated TRAC-G user's guide. GEH and AREVA have agreed to provide to the NRC the information referenced above in support of the NRC audit.

Enclosure 2 provides an affidavit by AREVA supporting the withholding from public disclosure of AREVA Document Number 51-9173927-000.

Duke Energy plans to provide the General Electric Hitachi (GEH) TRAC-G computer code base deck and associated user's guide under a separate letter. No regulatory commitments are contained in this letter. Please refer any questions regarding this submittal to Mr. Lee Grzeck, Manager -Regulatory Affairs, at (910) 457-2487.
