SUBJECT:

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 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, 50-410 and 72-1036 Person Responsible for Mr. John J. Dosa Providing additional information: 315-349-5219 Cask Certificate Number: 1004 Certificate Amendment Number: 10 Cask Model Number: NUHOMS-61BT Cask Identification Numbers: NMP61B-004-A, loaded October 29, 2012 NMP61B-005-A, loaded November 5, 2012 U Fk)S,2ý,

0 Document Control Desk November 28, 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 fourth and fifth DSCs in place at the NMPNS ISFSI is submitted for your information.

Horizontal Storage Module (HSM) Model: NUHOMS Model 102 HSM Identification Number: 7DFS-HSM004D Cask: NMP611B-004-A Calculated Heat Load: 7.43 kW Calculated AT: 40.0 degrees F Actual AT (Note 1): 26.5 degrees F HSM Identification Number: 7DFS-HSM004E Cask: NMP611B-005-A Calculated Heat Load: 7.45 kW Calculated AT: 40.0 degrees F Actual AT (Note 1): 27.9 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.
