On August 16, 2007 (72 FR 45880), the NRC published a direct final rule amending its regulations at 10 CFR 72.214 to revise the TN-68 cask system listing within the “List of Approved Spent Fuel Storage Casks” to include Amendment No. 1 to CoC No. 1027. This amendment modifies the CoC by revising several fuel parameters that include increasing fuel burnup to 60 gigawatts-day/metric ton of uranium, increasing total cask decay heat to 30 kilowatts, increasing maximum average fuel enrichment to 4.7 weight percent uranium-235, and decreasing minimum fuel assembly cooling time to 7 years. Amendment No. 1 will also add up to eight damaged fuel assemblies as authorized contents of the cask and reduce the cask spacing on the storage pad. In the direct final rule, NRC stated that if no significant adverse comments were received, the direct final rule would become final on October 30, 2007. The NRC did not receive any comments on the direct final rule. Therefore, this rule will become effective as scheduled.
