Box 63, Lycoming, NY 13093 Document Control DeskAugust 7, 2013Page 2The 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 forevaluation and assessment.

Additionally, this section of TS requires subsequent users of the system toreport heat loads higher than the first user. The first user of the NUHOMS CoC No. 1004, DukeEnergy, 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 August8, 2007 (ML072340622).

The first DSC loaded at NMPNS had a heat load of 7.30 kW, as reported inour letter dated October 17, 2012.A summary of the thermal performance of the seventh and eighth DSCs in place at the NMPNS ISFSI issubmitted for your information.

Horizontal Storage Module (HSM) Model: NUHOMS Model 102HSM Identification Number: 7DFS-HSM004G Cask: NMP61B-007-A Calculated Heat Load: 9 kWCalculated AT: 49 degrees FActual AT (Note 1): 47.5 degrees FHSM Identification Number: 7DFS-HSM004H Cask: NMP61B-008-A Calculated Heat Load: 8.98 kWCalculated AT: 48.1 degrees FActual AT (Note 1): 32.7 degrees FNote 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 overthree consecutive days.This letter contains no NRC commitments.
