The U.S. Nuclear Regulatory Commission (NRC) is withdrawing a direct final rule that would have amended the NRC's spent fuel storage regulations by revising the Holtec International HI-STORM 100 Cask System listing within the "List of approved spent fuel storage casks" to add Amendment No. 8, Revision No. 1. This rule would have superseded Amendment No. 8 (effective May 2, 2012, and corrected on November 16, 2012), to the Certificate of Compliance (CoC) No. 1014. The NRC is taking this action because it has received at least one significant adverse comment in response to a companion proposed rule that was concurrently published with the direct final rule.
