List of Approved Spent Fuel Storage Casks: TN Americas, LLC: Standardized NUHOMS® Horizontal Modular Storage System for Irradiated Nuclear Fuel, Certificate of Compliance No. 1004, Renewed Amendment No. 19

Issuing agencies

Abstract

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[supreg] 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. Amendment No. 19 revises the certificate of compliance to provide for a 61BTH improved basket design using staggered plates similar the 24PTH Type 3 basket approved in CoC 1004 Amendment 18 and similar to the EOS 37PTH and 89BTH baskets approved in CoC 1042. This will simplify construction, reduce weight and improve fabricability. Additional changes are proposed to address editorial corrections, consistency, and terminology clarifications.

List of Approved Spent Fuel Storage Casks: TN Americas, LLC: 
Standardized NUHOMS[supreg] Horizontal Modular Storage System for 
Irradiated Nuclear Fuel, Certificate of Compliance No. 1004, Renewed 
Amendment No. 19

AGENCY: Nuclear Regulatory Commission.

ACTION: Direct final rule; confirmation of effective date.

-----------------------------------------------------------------------

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[supreg] 
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. Amendment No. 
19 revises the certificate of compliance to provide for a 61BTH 
improved basket design using staggered plates similar the 24PTH Type 3 
basket approved in CoC 1004 Amendment 18 and similar to the EOS 37PTH 
and 89BTH baskets approved in CoC 1042. This will simplify 
construction, reduce weight and improve fabricability. Additional 
changes are proposed to address editorial corrections, consistency, and 
terminology clarifications.

DATES: The effective date of November 9, 2026, for the direct final 
rule published August 26, 2026 (91 FR 54941), is confirmed.

SUPPLEMENTARY INFORMATION: On August 26, 2026 (91 FR 54941), the NRC 
published a direct final rule amending its regulations in part 72 of 
title 10 of the Code of Federal Regulations to revise the TN Americas, 
LLC Standardized NUHOMS[supreg] Horizontal Modular Storage System for 
Irradiated Nuclear Fuel, Certificate of Compliance No. 1004 within the 
``List of approved spent fuel storage casks'' to include Amendment No. 
19.
    In the direct final rule, the NRC stated that if no significant 
adverse comments were received, the direct final rule would become 
effective on November 9, 2026. The NRC received and docketed three 
comment submissions on the companion proposed rule (91 FR 55028; August 
26, 2026). An electronic copy of the comments can be obtained from the 
Federal Rulemaking website at <a href="https://www.regulations.gov">https://www.regulations.gov</a> under Docket 
ID NRC-2026-2806 and is also available in ADAMS under Accession No. 
ML26286A192. The NRC evaluated the comments against the criteria 
described in the direct final rule and determined that the comments 
were not significant and adverse. Specifically, one commenter mentions 
higher heat load as a significant change. This higher heat load was 
reviewed by the NRC and is documented in section 5.1.1 of the safety 
evaluation report (SER) and determined to be acceptable. Another 
commenter questioned the lack of site-specific analyses. However, 
specific environmental assessments are not required as 10 CFR 
51.22(a)(12) contains a categorical exclusion. The same commenter 
challenged that the changes would create appreciable differences in 
performance of the cask; however, the staff evaluated all proposed 
changes and documented the results in the SER.
    Other comments were outside the scope of this rulemaking and did 
not oppose the rule; propose a change or an addition to the rule; or 
cause the NRC to make a change to the rule, the certificate of 
compliance, or the technical specifications. Therefore, this direct 
final rule will become effective as scheduled.

    Dated: October 30, 2026.
