SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC) is confirming the effective date of November 9, 2026, for the direct final rule that was published in the Federal Register on August 26, 2026. This direct final rule amended the TN Americas, LLC Standardized NUHOMS® Horizontal Modular Storage System for Irradiated Nuclear Fuel listing within the “List of approved spent fuel storage casks” to include Amendment No. 19 to Certificate of Compliance No. 1004.

This will simplify construction, reduce weight and improve fabricability. Additional changes are proposed to address editorial corrections, consistency, and terminology clarifications.
