NUCLEAR REGULATORY COMMISSION

10 CFR Part 72

[NRC-2024-0180]
RIN 3150-AL21


List of Approved Spent Fuel Storage Casks: NAC International, 
Inc. MAGNASTOR[supreg] Storage System, Certificate of Compliance No. 
1031, Amendment No. 14 and Revisions to Amendment Nos. 0 Through 13

AGENCY: Nuclear Regulatory Commission.

ACTION: Proposed rule.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is proposing to 
amend its spent fuel regulations by revising the NAC International, 
Inc. MAGNASTOR[supreg] Storage System listing within the ``List of 
approved spent fuel storage casks'' to include Amendment No. 14 and 
revisions to Amendment Nos. 0 through 13 to Certificate of Compliance 
No. 1031. Amendment No. 14 and revisions to Amendment Nos. 0

[[Page 269]]

through 13 revise the certificate of compliance to add a revised method 
of evaluation for the non-mechanistic tipover accident, clarify in the 
technical specifications that damaged missing grid spacers only apply 
to pressurized-water reactor fuel assembles, clarify inlet and outlet 
vent blockage and surveillance requirements in limiting condition for 
operation 3.1.2 in Appendix A to the certificate of compliance and 
associated technical specification bases, and remove the reference to 
Type II Portland cement in the description of the certificate of 
compliance. The NRC is also correcting typographical errors in Revision 
1 to Amendment Nos. 11 to 13 and Amendment No. 14 to Certificate of 
Compliance No. 1031.

DATES: Submit comments by February 3, 2025. 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.

B. Submitting Comments

    The NRC encourages electronic comment submission through the 
Federal rulemaking website (https://www.regulations.gov). Please 
include Docket ID NRC-2024-0180 in your comment submission.
    The NRC cautions you not to include identifying or contact 
information that you do not want to be publicly disclosed in your 
comment submission. The NRC will post all comment submissions at 
https://www.regulations.gov as well as enter the comment submissions 
into ADAMS. The NRC does not routinely edit comment submissions to 
remove identifying or contact information.
    If you are requesting or aggregating comments from other persons 
for submission to the NRC, then you should inform those persons not to 
include identifying or contact information that they do not want to be 
publicly disclosed in their comment submission. Your request should 
state that the NRC does not routinely edit comment submissions to 
remove such information before making the comment submissions available 
to the public or entering the comment into ADAMS.

II. Rulemaking Procedure

    Because the NRC considers this action to be non-controversial, the 
NRC is publishing this proposed rule concurrently with a direct final 
rule in the Rules and Regulations section of this issue of the Federal 
Register. The direct final rule will become effective on March 19, 
2025. However, if the NRC receives any significant adverse comment by 
February 3, 2025, then the NRC will publish a document that withdraws 
the direct final rule. If the direct final rule is withdrawn, the NRC 
will address the comments in a subsequent final rule. In general, 
absent significant modifications to the proposed revisions requiring 
republication, the NRC will not initiate a second comment period on 
this action in the event the direct final rule is withdrawn.
    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.
    For a more detailed discussion of the proposed rule changes and 
associated analyses, see the direct final rule published in the Rules 
and Regulations section of this issue of the Federal Register.

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

[[Page 270]]

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 
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. 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). The NRC requests comment on the proposed rule with respect to 
clarity and effectiveness of the language used.

V. Availability of Documents

    The documents identified in the following table are available to 
interested persons as indicated.
