SUPPLEMENTARY INFORMATION:

On July 25, 2005 (70 FR 42485), the NRC published a direct final rule amending its regulations in 10 CFR part 72 to revise the NAC-UMS cask system listing within the “List of Approved Spent Fuel Storage Casks” to include Amendment No. 4 to CoC No. 1015. This amendment replaces the term “zircaloy” with the more generic term “zirconium alloy'; revises the definitions of “operable” and “site specific fuel”; revises vacuum drying pressure and time limits; revises short-term temperature limits and completion times for the heat removal system; clarifies the surface dose rate surveillance; adds a dissolved boron concentration option; deletes a redundant boron concentration administrative control; adds an alternate site-specific design basis earthquake analysis; and incorporates editorial and administrative changes. In the direct final rule, NRC stated that if no significant adverse comments were received, the direct final rule would become final on October 11, 2005. The NRC did not receive any comments that warranted withdrawal of the direct final rule. Therefore, this rule will become effective as scheduled.
