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® 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.
