SUBJECT:

Nine Mile Point Nuclear Station, Units 1 and 2 Renewed Facility Operating License Nos. DPR-63 and NPF-69 Docket Nos. 50-220 and 50-410 Nine Mile Point Nuclear Station Independent Spent Fuel Storage Installation General License Docket No. 72-1036 General License 30-day Cask Registration Notification and First System Thermal Performance Assessment Pursuant to the requirements of 10 CFR 72.212(b)(2), this letter provides the information to register the use of two approved spent fuel storage casks at the Nine Mile Point Nuclear Station (NMPNS)

Independent Spent Fuel Storage Installation (ISFSI).

Licensee's Name: Nine Mile Point Nuclear Station, LLC Address: PO Box 63 Lycoming, NY 13093 Reactor License Numbers: DPR-63 and NPF-69 Docket Numbers: 50-220, 50-4 10 and 72-1036 Person Responsible for Ms. Theresa H. Darling Providing additional information: 315-349-2221 Cask Certificate Number: 1004 Certificate Amendment Number: 10 Cask Model Number: NUHOMSO-61BT Cask Identification Numbers: NMP6 1B-007-A, loaded July 11, 2013 NMP61B-008-A, loaded July 23, 2013 Nine Mile Point Nuclear Station, LLC P.O. Box 63, Lycoming, NY 13093

Document Control Desk August 7, 2013 Page 2 The Technical Specifications (TS) for Certificate of Compliance (CoC) No. 1004, Amendment No. 10,

§1.1.7 "Special Requirements for First System in Place", requires the results of the temperature measurements of the first Dry Shielded Canister (DSC) placed in service be submitted to the NRC for evaluation and assessment. Additionally, this section of TS requires subsequent users of the system to report heat loads higher than the first user. The first user of the NUHOMS CoC No. 1004, Duke Energy, submitted the heat transfer characteristics for an 18.95 kilowatt (kW) Dry Shielded Canister (DSC) in a letter to the NRC, from Duke Energy, "Cask Certificate of Compliance, Docket No.: 72-1004, 30-day Report for Higher Canister Heat Loading per General Requirement Section 1.1.7," dated August 8, 2007 (ML072340622). The first DSC loaded at NMPNS had a heat load of 7.30 kW, as reported in our letter dated October 17, 2012.

A summary of the thermal performance of the seventh and eighth DSCs in place at the NMPNS ISFSI is submitted for your information.

Horizontal Storage Module (HSM) Model: NUHOMS Model 102 HSM Identification Number: 7DFS-HSM004G Cask: NMP61B-007-A Calculated Heat Load: 9 kW Calculated AT: 49 degrees F Actual AT (Note 1): 47.5 degrees F HSM Identification Number: 7DFS-HSM004H Cask: NMP61B-008-A Calculated Heat Load: 8.98 kW Calculated AT: 48.1 degrees F Actual AT (Note 1): 32.7 degrees F Note 1: The actual AT represents the measured AT obtained during equilibrium conditions. Equilibrium conditions were achieved when the daily temperature change observed was less than 6 degrees F over three consecutive days.
