NUCLEAR REGULATORY COMMISSION

10 CFR Part 72

[NRC-2024-0200]
RIN 3150-AL23


List of Approved Spent Fuel Storage Casks: NAC Multi-Purpose 
Canister (NAC-MPC) System, Certificate of Compliance No. 1025, 
Amendment No. 9, and Revision to Amendment Nos. 6, 7, and 8

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 Multi-Purpose 
Canister (NAC-MPC) System listing within the ``List of approved spent 
fuel storage casks'' to include Amendment No. 9 and revise Amendment 
Nos. 6, 7, and 8 to Certificate of Compliance (CoC) No. 1025. The 
addition of Amendment No. 9 and the revisions to Amendment Nos. 6, 7, 
and 8 amend the description of the vertical concrete cask (VCC) in the 
CoC and technical specifications to make a distinction between the VCC 
body and the VCC lid, in terms of applicability of the American 
Concrete Institute (ACI) Specifications ACI 349 and ACI 318.

DATES: This direct final rule is effective May 13, 2025, unless 
significant adverse comments are received by March 31, 2025. 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direct final rule is withdrawn as a result of such comments, timely 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. 9 
and the revision to Amendment Nos. 6, 7, and 8 to CoC No. 1025 and does 
not include other aspects of the NAC-MPC 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 
May 13, 2025. However, if the NRC receives any significant adverse 
comment on this direct final rule by March 31, 2025, 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 
March 9, 2000 (65 FR 12444), that approved the NAC-MPC system design 
and added it to the list of NRC-approved cask designs in Sec.  72.214 
as CoC No. 1025.

IV. Discussion of Changes

    On September 7, 2023 (ML23250A056), NAC International, Inc. 
submitted a request to the NRC to amend CoC No. 1025. NAC 
International, Inc. supplemented its request on the following dates: 
February 14, 2024 (ML24040A027), May 14, 2024 (ML24135A322), July 10, 
2024 (ML24193A110), and August 27, 2024 (ML24240A133). The addition of 
Amendment No. 9 and revision of Amendment Nos. 6, 7, and 8 revises the 
renewed CoC to:
     Revise the NAC-MPC system description in the CoC to 
distinguish between the VCC body and VCC lid and clearly indicate that 
only the VCC body is a reinforced concrete structure.
     Revise the CoC appendix A (Appendix A, ``Technical 
Specifications'') definitions, by revising the definition of VCC, and 
adding a new definition for VCC lid.
     Revise the CoC appendix B (Appendix B, ``Approved Contents 
and Design Features''), Section 3.3, ``Codes and Standards'' to 
indicate that the ACI 349 and ACI 318 govern the design and 
construction only of the VCC body. New text is added to provide the 
fabrication requirements for the concrete in the VCC lid to include:

--the minimum concrete density,
--the allowable methods for measuring the density of the concrete in 
the VCC lid, and
--requirements for the concrete mix, placement, and curing methods used 
in the construction of the concrete in the VCC lid.

     Correct conflicting information in the final safety 
analysis report design bases regarding the minimum concrete density in 
the VCC lid, to indicate a minimum concrete density of 140 pounds per 
cubic foot (pcf) and revise the shielding analysis and calculation to 
reflect the 140 pcf concrete density.
    The changes to the aforementioned documents are identified with 
revisions bars in the margin of each document.
    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 addition 
of Amendment No. 9 and revision of Amendment Nos. 6, 7, and 8 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 NAC-MPC system design, 
when used under the conditions specified in the CoC, 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

[[Page 10783]]

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-MPC system that meet the criteria in the addition 
of Amendment No. 9 and revision of Amendment Nos. 6, 7, and 8 to CoC 
No. 1025.

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-MPC 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 
based on this environmental assessment.

A. The Action

    The action is to amend Sec.  72.214 to revise the NAC-MPC system 
listing within the ``List of approved spent fuel storage casks'' to add 
Amendment No. 9 and revise Amendment Nos. 6, 7, and 8 to Certificate of 
Compliance No. 1025.

B. The Need for the Action

    This direct final rule amends the certificate of compliance for the 
NAC-MPC 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, addition of Amendment No. 9 and revision of Amendment 
Nos. 6, 7, and 8 revises the CoC to:
     Revise the NAC-MPC system description in the CoC to 
distinguish between the VCC body and VCC lid and clearly indicate that 
only the VCC body is a reinforced concrete structure.
     Revise the CoC appendix A (Appendix A, ``Technical 
Specifications'') definitions, by revising the definition of VCC, and 
adding a new definition for VCC lid.
     Revise the CoC appendix B (Appendix B, ``Approved Contents 
and Design Features''), Section 3.3, ``Codes and Standards'' to 
indicate that the ACI 349 and ACI 318 govern the design and 
construction only of the VCC body. New text is added to provide the 
fabrication requirements for the concrete in the VCC lid to include:

--the minimum concrete density,
--the allowable methods for measuring the density of the concrete in 
the VCC lid, and
--requirements for the concrete mix, placement, and curing methods used 
in the construction of the concrete in the VCC lid.

     Correct conflicting information in the final safety 
analysis report design bases regarding the minimum concrete density in 
the VCC lid, to indicate a minimum concrete density of 140 pounds per 
cubic foot (pcf) and revise the shielding analysis and calculation to 
reflect the 140 pcf concrete density.

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 addition of Amendment No. 9 and 
revision of Amendment Nos. 6, 7, and 8 tiers from 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-MPC 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 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 
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 the addition of Amendment No. 9 and 
revision of Amendment Nos. 6, 7, and 8 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 the addition 
of Amendment No. 9 and revision of Amendment Nos. 6, 7, and 8 and not 
issue the direct final rule. Consequently, any 10 CFR part 72 general 
licensee that seeks to load spent nuclear fuel into

[[Page 10784]]

NAC-MPC system design in accordance with the changes described in 
proposed addition of Amendment No. 9 and revision of Amendment Nos. 6, 
7, and 8 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 the addition of Amendment No. 9 and revision of 
Amendment Nos. 6, 7, and 8 to CoC No. 1025 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, ``NAC Multi-
Purpose Canister (NAC-MPC) System, Certificate of Compliance No. 1025, 
Amendment No. 9, and Revision to Amendment Nos. 6, 7, and 8,'' 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 CoC; and (3) the 
conditions of the general license are met. A list of NRC-approved cask 
designs is contained in Sec.  72.214. On March 9, 2000 (65 FR 12444), 
the NRC issued an amendment to 10 CFR part 72 that approved the NAC-MPC 
system by adding it to the list of NRC-approved cask designs in Sec.  
72.214.
    On September 7, 2023 (ML23250A056), and as supplemented on February 
14, 2024 (ML24040A027), May 14, 2024 (ML24135A322), July 10, 2024 
(ML24193A110), and August 27, 2024 (ML24240A133), NAC International, 
Inc. submitted a request to amend the NAC-MPC system as described in 
Section IV, ``Discussion of Changes,'' of this document.
    The alternative to this action is to withhold approval of the 
addition of Amendment No. 9, and revision of Amendment Nos. 6, 7, and 8 
and to require any 10 CFR part 72 general licensee seeking to load 
spent nuclear fuel into the NAC-MPC system, CoC No. 1025, under the 
changes described in the addition of Amendment No. 9, and revision of 
Amendment Nos. 6, 7, and 8, 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 available 
alternative is believed to be as satisfactory; therefore, this action 
is recommended.

XII. Backfitting and Issue Finality

    General licensees using the specific CoC amendments that are being 
revised are required to meet the conditions of the revised CoC. The NRC 
added a condition to the revised CoC that requires the general 
licensees to implement the revised CoC within six months and perform 
written evaluations in accordance with 10 CFR 72.212(b)(5), which 
establish that the cask will conform to the terms, conditions, and 
specifications of the revised CoC. The six-month timeframe in the 
condition is considered a standard timeframe for implementation, 
consistent with the information in Regulatory Issue Summary 2017-05, 
``Administration of 10 CFR Part 72 Certificate of Compliance 
Corrections and Revisions.'' Additionally, the implementation timeframe 
was recognized by the applicant and the general licensees using these 
amendments (ML23250A056 and ML24193A110).
    For the following reasons, the NRC has determined that the 
regulations in 10 CFR 72.62, ``Backfitting,'' do not apply to this 
direct final rule. This direct final rule revises Amendment Nos. 6, 7, 
and 8 for renewed CoC No. 1025 for the NAC-MPC System, as currently 
listed in 10 CFR 72.214, ``List of approved spent fuel storage casks.'' 
Revision 1 to Amendment Nos. 6, 7, and 8 to renewed CoC No. 1025 
revises the NAC-MPC system description to distinguish between the VCC 
body and VCC lid, revise the definition of VCC and add a new definition 
for VCC lid, and add new fabrication requirements for the concrete in 
the VCC lid.
    NAC International, Inc. has manufactured casks under existing CoC 
No. 1025, Amendment Nos. 6, 7, or 8, that are being revised by this 
final rule. As the vendor, NAC International, Inc. is not within the 
scope of the backfitting provisions in 10 CFR 72.62.

[[Page 10785]]

    Under 10 CFR 72.62, general licensees are entities that are within 
the scope of the backfitting regulations. However, according to NAC 
International, Inc. (ML24193A110), no general licensees are currently 
storing NAC-MPC systems under CoC No. 1025, Amendment No. 6, which is, 
in part, the subject of these revisions. Therefore, because CoC No. 
1025, Amendment No. 6 is not in use by a licensee, the changes in the 
revision to CoC No. 1025, Amendment No. 6, which are approved in this 
direct final rule do not fall within the definition of backfitting 
under 10 CFR 72.62.
    Dairyland Power Cooperative at its La Crosse Boiling Water Reactor 
independent spent fuel storage installation (ISFSI) is the only general 
licensee using Amendment No. 7 that could be affected by the issuance 
of Revision 1 to Amendment No. 7. In its letters to NAC (ML23250A056 
and ML24193A110), Dairyland Power Cooperative stated that it intends to 
implement the revision to Amendment No. 7, as soon as practical after 
it is issued, and noted that all previously fabricated systems on site 
will be recertified to the adopted amendment revision. Because the 
licensee voluntarily intends to implement the revision, the issuance of 
Revision 1 to Amendment No. 7 does not fall within the definition of 
backfitting under 10 CFR 72.62.
    Connecticut Yankee Atomic Power Company at its Haddam Neck Plant 
ISFSI and Yankee Atomic Electric Company at its Yankee Nuclear Power 
Station ISFSI are the two general licensees using Amendment No. 8 that 
could be affected by the issuance of Revision 1 to Amendment No. 8. In 
its letter to NAC (ML23250A056), Connecticut Yankee Atomic Power 
Company stated that it intends to adopt Revision 1 to Amendment No. 8 
following NRC approval and issuance. Yankee Atomic Electric Company 
also stated in its letter (ML23250A056) that it intends to adopt 
Revision 1 to Amendment No. 8 following NRC approval and issuance. The 
licensees noted that the proposed changes do not directly impact the 
Haddam Neck Plant ISFSI and Yankee Nuclear Power Station ISFSI, because 
the sites utilize solid carbon steel lids for the VCCs they store. 
Because both licensees voluntarily intend to implement the revision, 
issuance of Revision 1 to Amendment No. 8 does not fall within the 
definition of backfitting under 10 CFR 72.62.
