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 NU HOMS Coe 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).
