List of Approved Spent Fuel Storage Casks - Transnuclear, Inc., Standardized NUHOMS HD Horizontal Modular Storage System, Amendment 2

Docket ID: NRC-2013-0269
Agency: Nuclear Regulatory Commission (NRC)
The direct final rule amends the Commission's regulations by revising the Transnuclear, Inc., NUHOMS HD Cask System listing within the "List of Approved Spent Fuel Storage Casks" to include Amendment No. 2 to Certificate of Compliance No. 1030. The direct final rule allows holders of power reactor operating licensees to store spent fuel in this approved cask system under a general license. Amendment 2 would revise authorized contents to increase the soluble boron concentration to 2,800 ppm for criticality safety analyses and add maximum enrichments for Combustion Engineering 14x14 fuel assemblies that were previously unauthorized for storage; improve clarity of certain technical specifications, such as heat load zoning configuration fuel qualification table fuel class and intact fuel/damaged fuel definitions; allow for increased fuel assembly weight by 25 pounds; revise the definition of control components; include blended low enriched uranium fuel material; increase shielding effectiveness of the horizontal storage module by adding optional dose reduction hardware; update licensing basis documents based on recent experience with ongoing licensing actions involving other NUHOMS systems; and accommodate installation practices for a limiting gap size that was evaluated based on dose rates. In addition, the amendment makes editorial changes to the technical specifications.
