UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 March 17, 2015 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

SUBJECT:

NINE MILE POINT NUCLEAR STATION, UNIT 1 - CORRECTION LETTER TO AMENDMENT NO. 217 RE: DIESEL GENERATOR INITIATION-DEGRADED VOLTAGE TIME DELAY SETTING CHANGE (TAC NO. MF1022)

Dear Mr. Orphanos:

By letter dated March 12, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML15043A270), the Commission issued Amendment No. 217 to Facility Operating License No. DPR-63 for Nine Mile Point, Unit No. 1 (NMP1 ).

The amendment to the NMP1 Renewed Facility Operating License DPR-63 modified Technical Specification Table 3.6.2i, "Diesel Generator Initiation," by revising the existing 4.16kV Power Board (PB) 102/103 Emergency Bus Undervoltage (Degraded Voltage) Operating Time value and updating the Set Point heading title. In addition, subsequent to the issuance of the proposed amendment by the U.S. Nuclear Regulatory Commission, the NMP1 Updated Final Safety Analysis Report (UFSAR) Table XV-9, "Significant Input Parameters to the Loss-Of-Coolant Accident (LOCA) Analysis," should be revised based on the issued amendment, to add a note regarding maximum allowable delay time from initiating signal to rated pump speed settings, to address the scenario of degraded grid voltage coincident with a LOCA.

Your staff recently informed the Nuclear Regulatory Commission of an inadvertent typographical error on Page 3 of the license. The error was an incorrectly entered amendment number in paragraph C(2).

P. M. Orphanos A corrected Page 3 of the Renewed Facility Operating License is enclosed. Please feel free to contact me at 301-415-3308 if you have any questions.

Sincerely,

• ~~~
