Nuclear Regulatory Commission Washington, DC 20555-0001 ATTN: Document Control Desk Director, Division of Spent Fuel Storage and Transportation Office of Nuclear Material Safety and Safeguards 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

SUBJECT:

General License 30-day Cask Registration Notification and 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: Address: Reactor License Numbers: Docket Numbers: Person Responsible for Providing additional information:

Cask Certificate Number: Certificate Amendment Number: Cask Model Number: Cask Identification Numbers: Nine Mile Point Nuclear Station, LLC PO Box 63 Lycoming, NY 13093 DPR-63 and NPF-69 50-220, 50-410 and 72-1036 Mr. Kenneth J. Kristensen 315-349-2069 1004 10 NUHOMSO-61 BTH NMP-61 BTH-1 -A-2-021, loaded June 11, 2015 NMP-61 BTH-1 -A-2-022, loaded June 25, 2015 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).

Theý,IjA k f>2v'(o ii-I 30 Day Cask July 9, 2015 Page 2 Registration 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 21st and 22nd DSCs in place at the NMPNS ISFSI is submitted for your information.

Horizontal Storage Module (HSM) Model: HSM Identification Number: 7DF Cask: NM Calculated Heat Load: 11., Calculated AT: 56 Actual AT (Note 1): 42.HSM Identification Number: 7DF Cask: NM Calculated Heat Load: 11., Calculated AT: 54 Actual AT (Note 1): 44.: NUHOMS Model 102:S-HSM002A P-61 BTH-1 -A-2-021 4585 kW degrees F 15 degrees F:S-HSM002B P-61 BTH-1 -A-2-022 4258 kW degrees F 35 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.
