The Nuclear Regulatory Commission (NRC) is confirming the effective date of December 26, 2000, for the direct final rule that appeared in the Federal Register of October 11, 2000 (65 FR 60339).

The seven areas involve: revision of the existing fuel specification tables; addition of pressurized water reactor Burnable Poison Rod Assemblies and Thimble Plug Devices; addition of two new classes of fuel to the fuel specification tables; addition of a new damaged fuel container; addition of thoria rods in canisters; addition of antimony-beryllium neutron sources [i.e., reactor startup sources], and clarifications, editorial corrections, and other minor changes to cask design information and drawings. In addition, the amendment includes two minor changes to HI-STAR 100 listing in the regulations. This document confirms the effective date.
