NUCLEAR REGULATORY COMMISSION

10 CFR Part 72

[NRC-2026-2806]
RIN 3150-AL72


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.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is amending its 
spent fuel storage regulations by revising 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 (CoC) 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. The NRC is 
referring to this amendment as ``Renewed Amendment No. 19'' because it 
was submitted after the renewal of the TN Americas, LLC Standardized 
NUHOMS Horizontal Modular Storage System for Irradiated Nuclear Fuel 
Certificate of Compliance No. 1004 and, therefore, subject to the Aging 
Management Program requirements of the renewed certificate.

DATES: This direct final rule is effective November 9, 2026, unless 
significant adverse comments are received by September 25, 2026. If 
this direct final rule is withdrawn as a result of such comments, 
timely notice of the withdrawal will be published in the Federal 
Register. Comments received after this date will be considered if it is 
practical to do so, but the NRC is able to ensure consideration only 
for comments received on or before this date. Comments received on this 
direct final rule will also be considered to be comments on a companion 
proposed rule published in the Proposed Rules section of this issue of 
the Federal Register.

II. Rulemaking Procedure

    This rule is limited to the changes contained in Amendment No. 19 
to Certificate of Compliance No. 1004 and does not include other 
aspects of the TN Americas, LLC Standardized NUHOMS[supreg] Horizontal 
Modular Storage System for Irradiated Nuclear Fuel system design. The 
NRC is using the ``direct final rule procedure'' to issue this 
amendment because it represents a limited and routine change to an 
existing certificate of compliance that is expected to be non-
controversial. Adequate protection of public health and safety 
continues to be reasonably assured. The amendment to the rule will 
become effective on November 9, 2026. However, if the NRC receives any 
significant adverse comment on this direct final rule by September 25, 
2026, then the NRC will publish a document that withdraws this action 
and will subsequently address the comments received in a final rule as 
a response to the companion proposed rule published in the Proposed 
Rules section of this issue of the Federal Register or as otherwise 
appropriate. In general, absent significant modifications to the 
proposed revisions requiring republication, the NRC will not initiate a 
second comment period on this action.
    A significant adverse comment is a comment where the commenter 
explains why the rule would be inappropriate, including challenges to 
the rule's underlying premise or approach, or would be ineffective or 
unacceptable without a change. A comment is adverse and significant if:
    (1) The comment opposes the rule and provides a reason sufficient 
to require a substantive response in a notice-and-comment process. For 
example, a substantive response is required when:
    (a) The comment causes the NRC to reevaluate (or reconsider) its 
position or conduct additional analysis;
    (b) The comment raises an issue serious enough to warrant a 
substantive response to clarify or complete the record; or
    (c) The comment raises a relevant issue that was not previously 
addressed or considered by the NRC.
    (2) The comment proposes a change or an addition to the rule, and 
it is apparent that the rule would be ineffective or unacceptable 
without incorporation of the change or addition.
    (3) The comment causes the NRC to make a change (other than 
editorial) to the rule, certificate of compliance, or technical 
specifications.

III. Background

    Section 218(a) of the Nuclear Waste Policy Act of 1982, as amended, 
requires that ``[t]he Secretary [of the Department of Energy] shall 
establish a demonstration program, in cooperation with the private 
sector, for the dry storage of spent nuclear fuel at civilian nuclear 
power reactor sites, with the objective of establishing one or more 
technologies that the [Nuclear Regulatory] Commission may, by rule, 
approve for use at the sites of civilian nuclear power reactors 
without, to the maximum extent practicable, the need for additional 
site-specific approvals by the Commission.'' Section 133 of the Nuclear 
Waste Policy Act states, in part, that ``[t]he Commission shall, by 
rule, establish procedures for the licensing of any technology approved 
by the Commission under Section 219(a) [sic: 218(a)] for use at the 
site of any civilian nuclear power reactor.''
    To implement this mandate, the Commission approved dry storage of 
spent nuclear fuel in NRC-approved casks under a general license by 
publishing a final rule that added a new subpart K in part 72 of title 
10 of the Code of Federal Regulations (10 CFR) entitled ``General 
License for Storage of Spent Fuel at Power Reactor Sites'' (55 FR 
29181; July 18, 1990). This rule also established a new subpart L in 10 
CFR part 72 entitled ``Approval of Spent Fuel Storage Casks,'' which 
contains procedures and criteria for obtaining NRC approval of spent 
fuel storage cask designs. The NRC subsequently issued a final rule on 
December 22, 1994 (59 FR 65898) that approved the Standardized 
NUHOMS[supreg] Horizontal Modular Storage System for Irradiated Nuclear 
Fuel System design and added it to the list of NRC-approved cask 
designs in Sec.  72.214 as Certificate of Compliance No.1004.

[[Page 54943]]

IV. Discussion of Changes

    On November 5, 2024, and as supplemented on February 20, 2025, and 
August 26, 2025, TN Americas, LLC submitted a request to the NRC to 
amend Certificate of Compliance No. 1004 for the Standardized 
NUHOMS[supreg] Horizontal Modular Storage System for Irradiated Nuclear 
Fuel. Renewed Amendment No. 19 revises the certificate and technical 
specifications to provide a 61BTH basket design using staggered plates 
similar to the 24PTH Type 3 basket to simplify construction, reduce 
weight, and improve fabricability; and to provide editorial 
corrections, consistency and terminology clarifications for Updated 
Final Safety Analysis Report Technical Specifications, Appendix A, B, 
and C.
    As documented in the preliminary safety evaluation report, the NRC 
performed a safety evaluation of the proposed certificate of compliance 
amendment request. The NRC determined that this amendment does not 
reflect a significant change in design or fabrication of the cask. 
Specifically, the NRC determined that the design of the cask would 
continue to maintain confinement, shielding, and criticality control in 
the event of each evaluated accident condition. In addition, any 
resulting occupational exposure or offsite dose rates from the 
implementation of Amendment No. 19 would remain well within the limits 
specified by 10 CFR part 20, ``Standards for Protection Against 
Radiation.'' Thus, the NRC found there will be no significant change in 
the types or amounts of any effluent released, no significant increase 
in the individual or cumulative radiation exposure, and no significant 
increase in the potential for or consequences from radiological 
accidents.
    The NRC staff determined that the amended Standardized 
NUHOMS[supreg] Horizontal Modular Storage System for Irradiated Nuclear 
Fuel cask design, when used under the conditions specified in the 
certificate of compliance, the technical specifications, and the NRC's 
regulations, will meet the requirements of 10 CFR part 72; therefore, 
adequate protection of public health and safety will continue to be 
reasonably assured. When this direct final rule becomes effective, 
persons who hold a general license under Sec.  72.210 may, consistent 
with the license conditions under Sec.  72.212, load spent nuclear fuel 
into Standardized NUHOMS[supreg] Horizontal Modular Storage System for 
Irradiated Nuclear Fuel casks that meet the criteria of Amendment No. 
19 to Certificate of Compliance No. 1004.

V. Voluntary Consensus Standards

    The National Technology Transfer and Advancement Act of 1995 (Pub. 
L. 104-113) requires that Federal agencies use technical standards that 
are developed or adopted by voluntary consensus standards bodies unless 
the use of such a standard is inconsistent with applicable law or 
otherwise impractical. In this direct final rule, the NRC revises the 
Standardized NUHOMS[supreg] Horizontal Modular Storage System for 
Irradiated Nuclear Fuel Cask System design listed in Sec.  72.214, 
``List of approved spent fuel storage casks.'' This action does not 
constitute the establishment of a standard that contains generally 
applicable requirements.

VI. Agreement State Compatibility

    Under the ``Agreement State Program Policy Statement'' approved by 
the Commission on October 2, 2017, and published in the Federal 
Register on October 18, 2017 (82 FR 48535), this rule is classified as 
Compatibility Category NRC--Areas of Exclusive NRC Regulatory 
Authority. The NRC program elements in this category are those that 
relate directly to areas of regulation reserved to the NRC by the 
Atomic Energy Act of 1954, as amended, or the provisions of 10 CFR 
chapter I. Therefore, compatibility is not required for program 
elements in this category.

VII. Plain Writing

    The Plain Writing Act of 2010 (Pub. L. 111-274) requires Federal 
agencies to write documents in a clear, concise, and well-organized 
manner. The NRC has written this document to be consistent with the 
Plain Writing Act as well as the Presidential Memorandum, ``Plain 
Language in Government Writing,'' published June 10, 1998 (63 FR 
31885).

VIII. Environmental Assessment and Finding of No Significant Impact

    Under the National Environmental Policy Act of 1969, as amended, 
and the NRC's regulations in 10 CFR part 51, ``Environmental Protection 
Regulations for Domestic Licensing and Related Regulatory Functions,'' 
the NRC has determined that this direct final rule, if adopted, would 
not be a major Federal action significantly affecting the quality of 
the human environment and, therefore, an environmental assessment or 
environmental impact statement is not required (per 10 CFR 
51.22(a)(12)). The NRC has made a finding of no significant impact on 
this basis.

A. The Action

    The action is to amend Sec.  72.214 to revise 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.

B. The Need for the Action

    This direct final rule amends the certificate of compliance for the 
TN Americas, LLC Standardized NUHOMS[supreg] Horizontal Modular Storage 
System for Irradiated Nuclear Fuel design within the list of approved 
spent fuel storage casks to allow power reactor licensees to store 
spent fuel at reactor sites in casks with the approved modifications 
under a general license. Specifically, Amendment No. 19 revises the 
certificate of compliance as described in Section IV, ``Discussion of 
Changes,'' of this document, for the use of the Standardized 
NUHOMS[supreg] Horizontal Modular Storage System.

C. Environmental Impacts of the Action

    On July 18,1990 (55 FR 29181), the NRC issued an amendment to 10 
CFR part 72 to provide for the storage of spent fuel under a general 
license in cask designs approved by the NRC. The potential 
environmental impact of using NRC-approved storage casks was analyzed 
in the environmental assessment for the 1990 final rule. The 
environmental assessment for this Amendment No. 19 tiers off of the 
environmental assessment for the July 18, 1990, final rule. Tiering on 
past environmental assessments is a standard process under the National 
Environmental Policy Act of 1969, as amended.
    The TN Americas, LLC Standardized NUHOMS[supreg] Horizontal Modular 
Storage System for Irradiated Nuclear Fuel is designed to mitigate the 
effects of design basis accidents that could occur during storage. 
Design basis accidents account for human-induced events and the most 
severe natural phenomena reported for the site and surrounding area. 
Postulated accidents analyzed for an independent spent fuel storage 
installation, the type of facility at which a holder of a power reactor 
operating license would store spent fuel in casks in accordance with 10 
CFR part 72, can include tornado winds and tornado-generated missiles, 
a design basis earthquake, a design basis flood, an accidental cask 
drop, lightning effects, fire, explosions, and other incidents.
    This amendment does not reflect a significant change in design or

[[Page 54944]]

fabrication of the cask. Because there are no significant design or 
process changes, any resulting occupational exposure or offsite dose 
rates from the implementation of Amendment No. 19 would remain well 
within the 10 CFR part 20 limits. The NRC has also determined that the 
design of the cask as modified by this rule would maintain confinement, 
shielding, and criticality control in the event of an accident. 
Therefore, the proposed changes will not result in any radiological or 
non-radiological environmental impacts that significantly differ from 
the environmental impacts evaluated in the environmental assessment 
supporting the July 18, 1990, final rule. There will be no significant 
change in the types or significant revisions in the amounts of any 
effluent released, no significant increase in the individual or 
cumulative radiation exposures, and no significant increase in the 
potential for, or consequences from, radiological accidents. The NRC 
documented its safety findings in the preliminary safety evaluation 
report.

D. Alternative to the Action

    The alternative to this action is to deny approval of Amendment No. 
19 and not issue the direct final rule. Consequently, any 10 CFR part 
72 general licensee that seeks to load spent nuclear fuel into The TN 
Americas, LLC Standardized NUHOMS[supreg] Horizontal Modular Storage 
System for Irradiated Nuclear Fuel in accordance with the changes 
described in proposed Amendment No. 19 would have to request an 
exemption from the requirements of Sec. Sec.  72.212 and 72.214. Under 
this alternative, interested licensees would have to prepare, and the 
NRC would have to review, a separate exemption request, thereby 
increasing the administrative burden upon the NRC and the costs to each 
licensee. The environmental impacts would be the same as the proposed 
action.

E. Alternative Use of Resources

    Approval of Amendment No. 19 to Certificate of Compliance No. 1004 
would result in no irreversible and irretrievable commitments of 
Federal resources.

F. Agencies and Persons Contacted

    No agencies or persons outside the NRC were contacted in connection 
with the preparation of this environmental assessment.

G. Finding of No Significant Impact

    The environmental impacts of the action have been reviewed under 
the requirements in the National Environmental Policy Act of 1969, as 
amended, and the NRC's regulations in subpart A of 10 CFR part 51, 
``Environmental Protection Regulations for Domestic Licensing and 
Related Regulatory Functions.'' Based on the foregoing environmental 
assessment, the NRC concludes that this direct final rule, ``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,'' 
will not have a significant effect on the human environment. Therefore, 
the NRC has determined that an environmental impact statement is not 
necessary for this direct final rule.

IX. Regulatory Planning and Review

    Executive Order (E.O.) 12866, as amended by E.O. 14215, provides 
that the Office of Information and Regulatory Affairs (OIRA) will 
determine whether a regulatory action is significant as defined by E.O. 
12866 and will review significant regulatory actions. OIRA determined 
that this direct final rule is not a significant regulatory action 
under E.O. 12866.

X. Paperwork Reduction Act Statement

    This direct final rule does not contain any new or amended 
collections of information subject to the Paperwork Reduction Act of 
1995 (44 U.S.C. 3501 et seq.). Existing collections of information were 
approved by the Office of Management and Budget, approval number 3150-
0132.

Public Protection Notification

    The NRC may not conduct or sponsor, and a person is not required to 
respond to, a request for information or an information collection 
requirement unless the requesting document displays a currently valid 
Office of Management and Budget control number.

XI. Regulatory Flexibility Certification

    Under the Regulatory Flexibility Act of 1980 (5 U.S.C. 605(b)), the 
NRC certifies that this direct final rule will not, if issued, have a 
significant economic impact on a substantial number of small entities. 
This direct final rule affects only nuclear power plant licensees and 
TN Americas LLC. These entities do not fall within the scope of the 
definition of small entities set forth in the Regulatory Flexibility 
Act or the size standards established by the NRC (Sec.  2.810).

XII. Regulatory Analysis

    On July 18, 1990 (55 FR 29181), the NRC issued an amendment to 10 
CFR part 72 to provide for the storage of spent nuclear fuel under a 
general license in cask designs approved by the NRC. Any nuclear power 
reactor licensee can use NRC-approved cask designs to store spent 
nuclear fuel if (1) it notifies the NRC in advance; (2) the spent fuel 
is stored under the conditions specified in the cask's certificate of 
compliance; and (3) the conditions of the general license are met. A 
list of NRC-approved cask designs is contained in Sec.  72.214. On 
December 22, 1994 (59 FR 65898), the NRC issued an amendment to 10 CFR 
part 72 that approved Standardized NUHOMS[supreg] Horizontal Modular 
Storage System for Irradiated Nuclear Fuel by adding it to the list of 
NRC-approved cask designs in Sec.  72.214.
    On November 5, 2024, and as supplemented on February 20, 2025, and 
August 26, 2025, TN Americas, LLC submitted a request to amend 
Certificate of Compliance No. 1004 for the Standardized NUHOMS[supreg] 
Horizontal Modular Storage System for Irradiated Nuclear Fuel as 
described in Section IV, ``Discussion of Changes,'' of this document.
    The alternative to this action is to withhold approval of Renewed 
Amendment No. 19 and to require any 10 CFR part 72 general licensee 
seeking to load spent nuclear fuel into the TN Americas, LLC 
Standardized NUHOMS[supreg] Horizontal Modular Storage System for 
Irradiated Nuclear Fuel under the changes described in Renewed 
Amendment No. 19 to request an exemption from the requirements of 
Sec. Sec.  72.212 and 72.214. Under this alternative, each interested 
10 CFR part 72 licensee would have to prepare, and the NRC would have 
to review, a separate exemption request, thereby increasing the 
administrative burden upon the NRC and the costs to each licensee.
    Approval of this direct final rule is consistent with previous NRC 
actions. Further, as documented in the preliminary safety evaluation 
report and environmental assessment, this direct final rule will have 
no adverse effect on public health and safety or the environment. This 
direct final rule has no significant identifiable impact or benefit on 
other government agencies. Based on this regulatory analysis, the NRC 
concludes that the requirements of this direct final rule are 
commensurate with the NRC's responsibilities for public health and 
safety and the common defense and security. No other

[[Page 54945]]

available alternative is believed to be as satisfactory; therefore, 
this action is recommended.

XIII. Backfitting and Issue Finality

    The NRC has determined that the backfit rule (Sec.  72.62) does not 
apply to this direct final rule. Therefore, a backfit analysis is not 
required. This direct final rule revises Certificate of Compliance No. 
1004 for the TN Americas, LLC Standardized NUHOMS[supreg] Horizontal 
Modular Storage System for Irradiated Nuclear Fuel, as currently listed 
in Sec.  72.214. The revision consists of the changes in Amendment No. 
19 previously described, as set forth in the revised certificate of 
compliance and technical specifications.
    Amendment No. 19 to Certificate of Compliance No. 1004 for the TN 
Americas, LLC Standardized NUHOMS[supreg] Horizontal Modular Storage 
System for Irradiated Nuclear Fuel was initiated by TN Americas, LLC 
and was not submitted in response to new NRC requirements, or an NRC 
request for amendment. Amendment No. 19 applies only to new casks 
fabricated and used under Amendment No. 19. These changes do not affect 
existing users of the TN Americas, LLC Standardized NUHOMS[supreg] 
Horizontal Modular Storage System for Irradiated Nuclear Fuel, and the 
current Amendment No. 18 continues to be effective for existing users. 
While current users of this storage system may comply with the new 
requirements in Amendment No. 19, this would be a voluntary decision on 
the part of current users.
    For these reasons, Amendment No. 19 to Certificate of Compliance 
No. 1004 does not constitute backfitting under Sec.  72.62 or Sec.  
50.109(a)(1), or otherwise represent an inconsistency with the issue 
finality provisions applicable to combined licenses in 10 CFR part 52. 
Accordingly, the NRC has not prepared a backfit analysis for this 
rulemaking.

XIV. Congressional Review Act

    This direct final rule is not a rule as defined in the 
Congressional Review Act.
