Additionally, this section of TS requiressubsequent users of the system to report heat loads higher than the first user. The first user ofthe NUHOMS CoC No. 1004, Duke Energy, submitted the heat transfer characteristics for an18.95 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 HeatLoading per General Requirement Section 1.1.7," dated August 8, 2007 (ML072340622).
