NUCLEAR REGULATORY COMMISSION
10 CFR Part 72
[NRC-2023-0085]
RIN 3150-AK99
List of Approved Spent Fuel Storage Casks: NAC International,
Inc. MAGNASTOR[supreg] Storage System, Certificate of Compliance No.
1031, Amendment Nos. 11 and 12 and Revisions to Amendment Nos. 0
Through 9
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 NAC International, Inc.
MAGNASTOR[supreg] Storage System listing within the ``List of approved
spent fuel storage casks'' to include Amendment Nos. 11 and 12 and
revisions to Amendment Nos. 0 through 9 to Certificate of Compliance
No. 1031. Amendment No. 11 amends the certificate of compliance to add
a new concrete cask, transfer cask, fuel baskets and revised contents.
Amendment No. 11 also adds a definition for the concrete cask lid,
revises the definition for the concrete cask to exclude the lid, adds a
definition for the storage cask, and provides alternate fabrication
criteria and techniques for the concrete cask lid. Amendment No. 12 and
revisions to Amendment Nos. 0 through 9 add definitions for the storage
cask and concrete cask lid, revise the definition of the concrete cask,
and provide alternate fabrication criteria and techniques for the
concrete cask lid to the certificate of compliance.
DATES: This direct final rule is effective October 16, 2023, unless
significant adverse comments are received by August 30, 2023. 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direct final rule is withdrawn as a result of such comments, timely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 Nos. 11
and 12 and revisions to Amendment Nos. 0 through 9 to Certificate of
Compliance No. 1031 and does not include other aspects of the NAC
International, Inc. MAGNASTOR[supreg] Storage 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 amendments to the rule will become effective on
October 16, 2023. However, if the NRC receives any significant adverse
comment on this direct final rule by August 30, 2023, 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,'' that
contains procedures and criteria for obtaining NRC approval of spent
fuel storage cask designs. The NRC subsequently issued a final rule on
November 21, 2008 (73 FR 70587), that approved the NAC International,
Inc. MAGNASTOR[supreg] Storage System design and added it to the list
of NRC-approved cask designs in Sec. 72.214 as Certificate of
Compliance No. 1031.
IV. Discussion of Changes
On July 14, 2020, NAC International, Inc. submitted a request to
the NRC to add Amendment No. 11 to Certificate of Compliance No. 1031.
NAC International, Inc. supplemented its request on August 23, 2021,
January 11, 2022, March 18, 2022, April 18, 2022, and July 15, 2022.
Amendment No. 11 amends the certificate of compliance as follows:
1. Adds a seventh concrete overpack (CC7) and a lightweight
MAGNASTOR[supreg] transfer cask (LMTC).
2. Increases the maximum heat load for the system when using CC7
and the LMTC.
3. Adds new loading patterns.
4. Adds new 81-assembly and 89-assembly boiling-water reactor (BWR)
spent fuel basket designs and associated loading patterns.
5. Removes existing 87-assembly and 82-assembly BWR basket designs.
6. Adds a new BWR damaged fuel basket design with a capacity of up
to 81 undamaged BWR fuel assemblies.
7. Adds a new damaged fuel can for BWR fuel.
8. Adds a definition for concrete cask lid.
9. Revises the definition for concrete cask to exclude the lid.
10. Adds a definition for storage cask.
11. Provides alternate fabrication criteria and techniques for the
concrete cask lid.
On January 24, 2022, NAC International, Inc. submitted a request to
the NRC to add Amendment No. 12 to Certificate of Compliance No. 1031.
NAC International, Inc. supplemented its request on March 18, 2022, and
April 18, 2022. As part of its request on March 18, 2022, as
supplemented on April 18, 2022, and August 4, 2022, NAC International,
Inc. also requested to revise Amendment Nos. 0 through 9 to Certificate
of Compliance No. 1031. Amendment No. 12 amends the certificate of
compliance as follows:
1. Adds a definition for concrete cask lid.
2. Revises the definition for concrete cask to exclude the lid.
3. Adds a definition for storage cask.
4. Provides alternate fabrication criteria and techniques for the
concrete cask lid.
Revision 2 to Amendment Nos. 0 through 3 and Revision 1 to
Amendments Nos. 4 through 9 revise the certificate of compliance to
incorporate the changes made by Amendment 12.
As documented in the preliminary safety evaluation reports, the NRC
performed safety evaluations of the proposed certificate of compliance
amendment requests. The NRC determined that these amendments do not
reflect a significant change in design or fabrication of the cask.
Specifically, the NRC determined that the design of the casks would
continue to maintain confinement, shielding, and criticality control in
the event of each evaluated
[[Page 49269]]
accident condition. 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. Therefore, any resulting occupational exposure
or offsite dose rates from the implementation of Amendment Nos. 11 and
12 and revisions to Amendment Nos. 0 through 9 would remain well within
the limits specified by 10 CFR part 20, ``Standards for Protection
Against Radiation.''
The NRC determined that the amended NAC International, Inc.
MAGNASTOR[supreg] Storage System 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 NAC International, Inc. MAGNASTOR[supreg]
Storage System casks that meet the criteria of the revised Amendment
Nos. 0 through 9 and newly issued Amendment Nos. 11 and 12 to
Certificate of Compliance No. 1031.
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
NAC International, Inc. MAGNASTOR[supreg] Storage 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 impact statement
is not required. The NRC has made a finding of no significant impact on
the basis of this environmental assessment.
A. The Action
The action is to amend Sec. 72.214 to revise the NAC
International, Inc. MAGNASTOR[supreg] Storage System listing within the
``List of approved spent fuel storage casks'' to include Amendment Nos.
11 and 12 and to include revisions to Amendment Nos. 0 through 9 to
Certificate of Compliance No. 1031.
B. The Need for the Action
This direct final rule amends the certificate of compliance for the
NAC International, Inc. MAGNASTOR[supreg] Storage System 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. 11 revises the certificate of compliance to add a new concrete
cask, transfer cask, fuel baskets and revised contents. Amendment No.
11 also adds a definition for the concrete cask lid, revises the
definition for the concrete cask to exclude the lid, adds a definition
for the storage cask, and provides alternate fabrication criteria and
techniques for the concrete cask lid. Amendment No. 12 and the
revisions to Amendment Nos. 0 through 9 add definitions for the storage
cask and concrete cask lid, revise the definition of the concrete cask,
and provide alternate fabrication criteria and techniques for the
concrete cask lid to the certificate of compliance.
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 Amendment Nos. 11 and 12 and revisions to
Amendment Nos. 0 through 9 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 NAC International, Inc. MAGNASTOR[supreg] Storage System 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 that 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
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 Nos. 11 and 12 and revisions
to Amendment Nos. 0 through 9 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
[[Page 49270]]
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
Nos. 11 and 12 and revisions to Amendment Nos. 0 through 9 and not
issue the direct final rule. Consequently, any 10 CFR part 72 general
licensee that seeks to load spent nuclear fuel into the NAC
International, Inc. MAGNASTOR[supreg] Storage System in accordance with
the changes described in proposed Amendment Nos. 11 and 12 and
revisions to Amendment Nos. 0 through 9, including those licensees with
fuel already loaded in casks that need these revisions, 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 Nos. 11 and 12 and revisions to Amendment
Nos. 0 through 9 to Certificate of Compliance No. 1031 would result in
no irreversible commitment of 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: NAC International, Inc.
MAGNASTOR[supreg] Storage System, Certificate of Compliance No. 1031,
Amendment Nos. 11 and 12 and Revisions to Amendment Nos. 0 through 9,''
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. 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.
X. 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
NAC International, Inc. 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).
XI. 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
November 21, 2008 (73 FR 70587), the NRC issued an amendment to 10 CFR
part 72 that approved the NAC International, Inc. MAGNASTOR[supreg]
Storage System design by adding it to the list of NRC-approved cask
designs in Sec. 72.214.
On July 14, 2020, and as supplemented on August 23, 2021, January
11, 2022, March 18, 2022, April 18, 2022, and July 15, 2022, NAC
International, Inc. submitted a request for Amendment No. 11 to amend
the MAGNASTOR[supreg] Storage System. On January 24, 2022, and as
supplemented on March 18, 2022 and April 18, 2022, NAC International,
Inc. submitted a request for Amendment No. 12 to amend the
MAGNASTOR[supreg] Storage System. Lastly, on March 18, 2022, and as
supplemented on April 18, 2022 and August 4, 2022, NAC International,
Inc. submitted a request to revise Amendment Nos. 0 through 9 of the
MAGNASTOR[supreg] Storage System. All of these changes are described in
Section IV, ``Discussion of Changes,'' of this document.
The alternative to this action is to withhold approval of Amendment
Nos. 11 and 12 and revisions to Amendment Nos. 0 through 9 and to
require any 10 CFR part 72 general licensee seeking to load spent
nuclear fuel into the NAC International, Inc. MAGNASTOR[supreg] Storage
System under the changes described in Amendment Nos. 11 and 12 and
revisions to Amendment Nos. 0 through 9 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
reports 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 available
alternative is believed to be as satisfactory; therefore, this action
is recommended.
XII. Backfitting
The NRC has determined that this direct final rule does not
constitute backfitting under 10 CFR part 72. Certificate of compliance
holders like NAC International, Inc. are not within the scope of the
backfit rule in Sec. 72.62. Additionally, Amendment Nos. 11 and 12 are
outside the scope of backfitting because they apply only to new casks
and are voluntary for existing users. Although general licensees that
are affected by the revisions to Amendment Nos. 0-9 are within the
scope of the backfitting regulations in Sec. 72.62, the affected
licensees have stated that they will voluntarily adopt the revisions,
and therefore, this direct final rule does not constitute a backfit for
those licensees.
[[Page 49271]]
This direct final rule revises Certificate of Compliance No. 1031
for the MAGNASTOR[supreg] Storage System, as currently listed in Sec.
72.214, to add Amendment Nos. 11 and 12 and revisions to Amendment Nos.
0 through 9. Amendment Nos. 11 and 12 and revisions to Amendment Nos. 0
through 9 to Certificate of Compliance No. 1031 for the NAC
International, Inc. MAGNASTOR[supreg] Storage System were initiated by
NAC International, Inc. and were not submitted in response to new NRC
requirements or an NRC request for amendment. Amendment Nos. 11 and 12
apply only to new casks fabricated and used under Amendment Nos. 11 and
12. These changes do not affect existing users of the NAC
International, Inc. MAGNASTOR[supreg] Storage System, and the current
Amendment No. 10 continues to be effective for existing users. While
current users of this storage system may comply with the new
requirements in Amendment Nos. 11 and 12, this would be a voluntary
decision on the part of current users. Although NAC International, Inc.
has manufactured casks under the existing Certificate of Compliance No.
1031, Amendment Nos. 0 through 9, NAC International, Inc., as the
certificate of compliance holder, is not within the scope of
backfitting under 10 CFR 72.62.
General licensees are entities that are within the scope of the
backfitting regulations in 10 CFR 72.62. However, according to NAC
International, Inc., no general licensees have purchased the
MAGNASTOR[supreg] Storage Systems under Certificate of Compliance No.
1031, Amendment Nos. 0 through 5 and Amendment No. 8, that are, in
part, the subject of these revisions. Therefore, the changes in
Certificate of Compliance No. 1031, Amendment Nos. 0 through 5 and
Amendment No. 8, that are approved in this direct final rule, do not
fall within the definition of backfitting under 10 CFR 72.62.
Dominion Energy Kewaunee at the Kewaunee independent spent fuel
storage installation and ZionSolutions at its independent spent fuel
storage installation are two general licensees using Amendment No. 6
that could be affected by issuance of Revision 1 to Amendment No. 6. In
its letter to NAC International, Inc., Dominion Energy Kewaunee stated
that it would voluntarily adopt Revision 1 to Amendment No. 6.
ZionSolutions stated it intends to rely on issuance of Revision 1 to
Amendment No. 6 and Amendment No. 12 to reconcile the lid licensing
issue and close the open action in its corrective action program. The
NRC interprets these letters to mean that the licensees will
voluntarily comply with Revision 1 to Amendment No. 6. Therefore, the
issuance of Revision 1 to Amendment No. 6 does not fall within the
definition of backfitting under 10 CFR 72.62.
Arizona Public Service Company at the Palo Verde independent spent
fuel storage installation and Duke Energy at the Catawba and McGuire
independent spent fuel storage installations are general licensees
using Amendment No. 7 that could be affected by issuance of Revision 1
to Amendment No. 7. In its letter to NAC International, Inc., both
Arizona Public Service Company and Duke Energy stated that they intend
to implement Revision 1 to Amendment No. 7. The NRC interprets these
letters to mean that the licensees will voluntarily comply with
Revision 1 to Amendment No. 7. Therefore, issuance of Revision 1 to
Amendment No. 7 does not fall within the definition of backfitting
under 10 CFR 72.62.

independent spent fuel storage installation is the only general
licensee using Amendment No. 9 that could be affected by issuance of
Revision 1 to Amendment No. 9. In its letter to NAC International,
Inc., Constellation Energy Generation stated that it intends to
implement Revision 1 to Amendment No. 9 in a timely manner after
issuance of the revision. The NRC interprets this letter to mean that
the licensee will voluntarily comply with Revision 1 to Amendment No.
9. Therefore, issuance of Revision 1 to Amendment No. 9 does not fall
within the definition of backfitting under 10 CFR 72.62.
For these reasons, Amendment Nos. 11 and 12 and revisions to
Amendment Nos. 0 through 9 to Certificate of Compliance No. 1031 do not
constitute backfitting under Sec. 72.62. Accordingly, the NRC does not
need to prepare a backfit analysis for this rulemaking.
XIII. Congressional Review Act
This direct final rule is not a rule as defined in the
Congressional Review Act.
