[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this direct final rule is withdrawn as a result of such comments,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.
