NUCLEAR REGULATORY COMMISSION

10 CFR Part 72

[NRC-2021-0052]
RIN 3150-AK63


List of Approved Spent Fuel Storage Casks: NAC International NAC-
UMS[supreg] Universal Storage System, Certificate of Compliance No. 
1015, Amendment No. 8

AGENCY: Nuclear Regulatory Commission.

ACTION: Proposed rule.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is proposing to 
amend its spent fuel storage regulations by revising the NAC 
International NAC-UMS[supreg] Universal Storage System listing within 
the ``List of approved spent fuel storage casks'' to include Amendment 
No. 8 to Certificate of Compliance No. 1015. Amendment No. 8 revises 
the certificate of compliance to add the storage of damaged boiling-
water reactor spent fuel, including higher enrichment and higher burnup 
spent fuel; change the allowable fuel burnup range; expand the boiling-
water reactor class 5 fuel inventory that could be stored in the cask; 
and revise definitions in the technical specifications.

DATES: Submit comments by September 7, 2021. 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.

ADDRESSES: Submit your comments, identified by Docket ID NRC-2021-0052,

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 October 19, 
2021. However, if the NRC receives any significant adverse comment by 
September 7, 2021, 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 If the direct final rule is withdrawn, the NRC 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. 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this action in the event the direct final rule is withdrawn.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, certificate of compliance, or technical 
specifications.
    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 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 casks approved for use under the terms, 
conditions, and specifications of their certificate of compliance or an 
amended certificate of compliance pursuant to this general license are 
listed in Sec.  72.214. The NRC subsequently issued a final rule on 
October 19, 2000 (65 FR 62581), that approved the NAC International 
NAC-UMS[supreg] Universal Storage System and added it to the list of 
NRC-approved cask designs in Sec.  72.214 as Certificate of Compliance 
No. 1015.
    The NAC International NAC-UMS[supreg] Universal Storage System 
consists of the following components: (1) Transportable storage 
canister (TSC), which contains the spent fuel; (2) vertical concrete 
cask, which contains the TSC during storage; and (3) a transfer cask, 
which contains the TSC during loading, unloading, and transfer 
operations. Amendment No. 8 revises the certificate of compliance to 
(1) add the storage of damaged boiling-water reactor spent fuel, 
including higher enrichment and higher burnup spent fuel; (2) change 
the allowable fuel burnup range; and (3) expand the boiling-water 
reactor class 5 fuel inventory that could be stored in the cask; and 
(4) change definitions in the technical specifications that are 
associated with the contents of the spent nuclear fuel stored in the 
cask (e.g., high burnup fuel and initial peak planar-average 
enrichment).

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.
