The U.S. Nuclear Regulatory Commission (NRC) is withdrawing a direct final rule that would have revised the Holtec International HI- STORM 100 cask system listing within the "List of Approved Spent Fuel Storage Casks" to include Amendment No. 5 to the Certificate of Compliance. The NRC is taking this action because it has received a significant adverse comment in response to the direct final rule. This significant adverse comment shall be considered as a comment to the companion proposed rule that was published concurrently with the direct final rule.
