OFFICIAL USE ONLY-PROPRIETARY INFORMATION UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Mr. Peter Orphanos Vice President Nine Mile Point Exelon Generation Company, LLC Nine Mile Point Nuclear Station, LLC P. 0. Box 63 Lycoming, NY 13093 September 2, 2015

SUBJECT:

NINE MILE POINT NUCLEAR STATION, UNIT NO. 2 - ISSUANCE OF AMENDMENT RE: MAXIMUM EXTENDED LOAD LINE LIMIT ANALYSIS PLUS (TAC NO. MF3056)

Dear Mr. Orphanos:

The Commission has issued the enclosed Amendment No. 151 to Renewed Facility Operating License No. NPF-69 for the Nine Mile Point Nuclear Station, Unit No. 2 (NMP2). The amendment consists of changes to the Technical Specifications (TSs) in response to your application transmitted by letter dated November 1, 2013, as supplemented by letters dated January 21, February 14, February 25, March 10, May 14, June 13, October 10, December 11, 2014, and February 18, 2015.

Further, as a part of its application for the license transfer and conforming amendment of the Renewed Facility Operating License for NMP2, in the letter dated March 28, 2014, (Agencywide Documents Access and Management System Accession No. ML14087A274) Exelon Generation has stated that:

Prior to the license transfers, GENG made docketed submittals to the NRG that requested specific licensing actions, such as license amendment requests, relief requests, exemption requests, etc. Furthermore, in the application for the license transfers, Exelon stated that upon transfer of the licenses, Exelon would assume all current regulatory commitments made for these units. Accordingly, Exelon hereby adopts and endorses those docketed requests currently before the NRG for review and approval. Exelon requests that the NRG continue to process those pending actions on the schedules previously requested by GENG.

The amendment includes changes to the NMP2 TSs necessary to: (1) implement the Maximum Extended Load Line Limit Analysis Plus (MELLLA+) expanded operating domain; (2) change the stability solution to Detect and Suppress Solution - Confirmation Density (DSS-CD); (3) use the TRACG04 analysis code; (4) increase the isotopic enrichment of boron-10 in the sodium pentaborate solution utilized in the Standby Liquid Control System (SLCS); and (5) increase the Safety Limit Minimum Critical Power Ratio (SLMCPR) for two recirculation loops in operation.

NOTICE: Enclosure to this letter contains Sensitive Internal Information Upon separation from the Enclosure, this letter is DECONTROLLED.
