SUBJECT:

Document Control Desk Director, Division of Spent Fuel Storage and Transportation Office of Nuclear Material Safety and Safeguards Nine Mile Point Nuclear Station Unit Nos. 1, 2 and ISFSI, Docket Nos. 50-220, 50-410 and 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 an 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 DPR-63 and NPF-69 Reactor License Numbers: Docket Numbers: 50-220, 50-410 and 72-1036 Person Responsible for Providing additional information:

Cask Certificate Number: Certificate Amendment Number: Cask Model Number: Cask Identification Numbers: Mr. John J. Dosa 315-349-5219 1004 10 NUHOMS-61BT NMP61B-006-A, loaded November 17, 2012 0 k 5ýý (4:;ý Document Control Desk November 30, 2012 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 sixth DSC in place at the NMPNS ISFSI is submitted for your information.

Horizontal Storage Module (HSM) Model: NUHOMS Model 102 HSM Identification Number: 7DFS-HSM004F Cask: NMP61B-006-A Calculated Heat Load: 7.29 kW Calculated AT: 39.0 degrees F Actual AT (Note 1): 33.5 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.This letter contains no NRC commitments.
