SUPPLEMENTARY INFORMATION: On October 3, 2023 (88 FR 67929), the NRC 
published a direct final rule amending its regulations in part 72 of 
title 10 of the Code of Federal Regulations to the TN Americas LLC, 
Standardized NUHOMS[supreg] Horizontal Modular Storage System for 
Irradiated Nuclear Fuel listing within the ``List of approved spent 
fuel storage casks'' to include Renewed Amendment No. 18 to Certificate 
of Compliance (CoC) No. 1004. Renewed Amendment No. 18 amends the 
certificate of compliance to:
     provide a 24PTH improved basket design (Type 3) using 
staggered plates similar to EOS-37PTH to simplify construction, reduce 
weight, and improve fabricability;
     delete Appendix A inspections, tests, and evaluations 
requirement for initial horizontal storage module delta temperature 
measurement with a loaded dry shielded canister (DSC);
     clarify Appendix B technical specification (TS) Section 
4.3.2 language related to transfer casks with liquid neutron shields 
regarding the OS197L transfer cask (TC), which is significantly 
different than other TC models;
     update Appendix C American Society of Mechanical Engineers 
(ASME) Code Alternatives Table C-12 to add code alternative NG-4231.1;
     clarify in Appendix B TS LCO 3.1.3 that there is no 
transfer time limit associated with the 24PTH-S-LC DSC, consistent with 
existing updated final safety analysis report analysis;
     incorporate administrative controls during short duration 
independent spent fuel storage installation handling operations that 
are unanalyzed for tornado hazards in accordance with the guidance 
contained in NRC EGM 22-001, ``Enforcement Discretion for Noncompliance 
of Tornado Hazards Protection Requirements at Independent Spent Fuel 
Storage Installations''; and
     change the horizontal storage module concrete, to allow 
use of different cement, which is a blended Portland cement meeting the 
requirements of the American Society for Testing and Materials C595 
standard.
    This amendment also includes an editorial correction to the 
certificate of compliance name/address information by adding a missing 
space between 7160 and Riverwood Drive.
    In the direct final rule, the NRC stated that if no significant 
adverse comments were received, the direct final rule would become 
effective on December 18, 2023. The NRC did not receive any comments on 
the direct final rule. Therefore, this direct final rule will become 
effective as scheduled.

    Dated: November 15, 2023.

    For the Nuclear Regulatory Commission.
