RIN 3150-AK67
List of Approved Spent Fuel Storage Casks: TN Americas LLC, TN-32
Dry Storage Cask, Certificate of Compliance No. 1021, Renewal of
Initial Certificate and Amendment No. 1
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, TN-32
Dry Storage Cask listing within the ``List of approved spent fuel
storage casks'' to renew, for an additional 40 years, the initial
certificate and Amendment No. 1 of Certificate of Compliance No. 1021.
The renewal of the initial certificate and Amendment No. 1 revises the
certificate of compliance's conditions and technical specifications to
address aging management activities related to the structures, systems,
and components of the dry storage system to ensure that these will
maintain their intended functions during the period of extended storage
operations. The scope of the Certificate of Compliance No. 1021 renewal
includes spent fuel storage cask models TN-32, TN-32A, and TN-32B.
DATES: This direct final rule is effective January 19, 2022, unless
significant adverse comments are received by December 6, 2021. 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direct final rule is withdrawn as a result of such comments, timely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 renewal of the initial certificate and
Amendment No. 1 of Certificate of Compliance No. 1021 and does not
include other aspects of the TN Americas LLC, TN-32 Dry Storage Cask
system design. The NRC is using the ``direct final rule procedure'' to
issue this renewal 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 January 19, 2022. However, if the NRC receives any
significant adverse comments on this direct final rule by December 6,
2021, 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. 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
[[Page 61049]]
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
20, 2000 (65 FR 14790), that approved the TN-32 Dry Storage Cask system
design and added it to the list of NRC-approved cask designs in Sec.
72.214 as Certificate of Compliance No. 1021.
IV. Discussion of Changes
On March 5, 2020, TN Americas LLC submitted a request to the NRC to
renew, for an additional 40 years, the initial certificate and
Amendment No. 1 of Certificate of Compliance No. 1021 for the TN-32 Dry
Storage Cask system. TN Americas LLC supplemented its request on
November 11, 2020; February 5, 2021; and March 17, 2021.
The renewal of the initial certificate and Amendment No. 1 was
conducted in accordance with the renewal provisions in Sec. 72.240.
This section of the NRC spent fuel storage regulations authorizes the
NRC to include any additional certificate conditions it deems necessary
to ensure the safe operation of the cask during the certificate's
renewal period. The NRC included three additional conditions to the
renewal of the initial certificate of compliance and Amendment No. 1:
The submittal of an updated final safety analysis report
(UFSAR) to address aging management activities resulting from the
renewal of the certificate of compliance. This condition ensures that
the UFSAR changes are made in a timely fashion to enable general
licensees using the storage system during the period of extended
operation to develop and implement necessary procedures.
The requirement that general licensees initiating or using
spent fuel dry storage operations with the TN-32 Dry Storage Cask
system ensure that their evaluations are included in the reports
required by Sec. 72.212, ``Conditions of general license issued under
Sec. 72.210.'' These reports will include appropriate considerations
for the period of extended operation, a review of the UFSAR changes
resulting from the certificate of compliance renewal, and a review of
the NRC safety evaluation report (SER) related to the certificate of
compliance renewal.
The requirement that future amendments and revisions to
this certificate of compliance include evaluations of the impacts to
aging management activities to ensure that they remain adequate for any
changes to the structures, systems, and components (SSCs).
The NRC made one corresponding change to the technical
specifications for the initial certificate of compliance and Amendment
No. 1. The change added a new section, which ensures that general
licensees using the storage system develop procedures to address aging
management activities required in the period of extended operation.
As documented in the preliminary SER, the NRC performed a safety
evaluation of the proposed certificate of compliance renewal request.
The NRC determined that this renewal does not change the cask design or
fabrication requirements in the proposed certificate of compliance
renewal request. 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 of offsite dose rates from the renewal
of the initial certificate of compliance and Amendment No. 1 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. In its SER for the renewal of
the TN-32 Dry Storage Cask system, the NRC staff has determined that if
the conditions specified in the certificate of compliance to implement
these regulations are met, adequate protection of public health and
safety will continue to be reasonably assured.
This direct final rule revises the TN-32 Dry Storage Cask listing
in Sec. 72.214 by renewing for 40 more years, the initial certificate
and Amendment No. 1 of Certificate of Compliance No. 1021. The renewal
consists of the changes previously described, as set forth in the
renewed initial certificate and amendment and their revised technical
specifications. The revised technical specifications are identified in
the SER.
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
TN Americas LLC TN-32 Dry Storage Cask 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. Although an Agreement State may not adopt
program elements reserved to the NRC, and the Category ``NRC'' does not
confer regulatory authority on the State, the State may wish to inform
its licensees of certain requirements by means consistent with the
particular State's administrative procedure laws.
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 TN-32 Dry Storage
Cask listing within the ``List of approved spent fuel storage casks''
to renew, for
[[Page 61050]]
an additional 40 years, the initial certificate and Amendment No. 1 of
Certificate of Compliance No. 1021.
B. The Need for the Action
This direct final rule renews the initial certificate and Amendment
No. 1 of Certificate of Compliance No. 1021 for the TN Americas LLC,
TN-32 Dry Storage Cask 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, this rule extends the expiration date
for the TN Americas LLC, TN-32 Dry Storage Cask certificate for an
additional 40 years, allowing a reactor licensee to continue using it
under general license provisions in an independent spent fuel storage
installation to store spent fuel in dry casks in accordance with 10 CFR
part 72.
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 renewal of the initial certificate
and Amendment No. 1 of Certificate of Compliance No. 1021 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. As required by
Sec. 72.240, applications for renewal of a spent fuel storage
certificate of compliance design are required to demonstrate that SSCs
important to safety will continue to perform their intended function
for the requested renewal term. As discussed in the NRC's SER for the
renewal of the initial certificate and Amendment No. 1, the NRC has
approved conditions in the renewed initial certificate and Amendment
No. 1 requiring the general licensee to implement the aging management
activities described in the renewal application and incorporated into
the UFSAR. These conditions ensure that the TN Americas LLC, TN-32 Dry
Storage Cask system will continue to perform its intended safety
functions and provide reasonable assurance of adequate protection of
public health and safety throughout the renewal period.
Incremental impacts from continued use of the TN-32 Dry Storage
Cask system under a general license for an additional 40 years are not
considered significant. When the general licensee follows all
procedures and administrative controls, including the conditions
established because of this renewal, no effluents are expected from the
sealed dry cask systems. Activities associated with cask loading and
decontamination may result in some small incremental liquid and gaseous
effluents, but these activities will be conducted under 10 CFR parts 50
and 52 reactor operating licenses, and effluents will be controlled
within existing reactor site technical specifications. Because reactor
sites are relatively large, any incremental offsite doses due to direct
radiation exposure from the spent fuel storage casks are expected to be
small, and when combined with the contribution from reactor operations,
well within the annual dose equivalent of 0.25 mSv (25 mrem) limit to
the whole body specified in Sec. 72.104. Incremental impacts on
collective occupational exposures due to dry cask spent fuel storage
are expected to be only a small fraction of the exposures from
operation of the nuclear power station.
The TN-32 Dry Storage Cask 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.
During the promulgation of the amendments that added subpart K to
10 CFR part 72 (55 FR 29181; July 18, 1990), the NRC staff assessed the
public health consequences of dry cask storage accidents and sabotage
events. In the supporting analyses for these amendments, the NRC
determined that a release from a dry cask storage system would be
comparable in magnitude to a release from the same quantity of fuel in
a spent fuel storage pool. As a result of these evaluations, the NRC
determined that, because of the physical characteristics of the storage
casks and conditions of storage that include specific security
provisions, the potential risk to public health and safety due to
accidents or sabotage is very small.
Considering the specific design requirements for each accident or
sabotage condition, the design of the cask would maintain confinement,
shielding, and criticality control. If confinement, shielding, or
criticality control are maintained, the environmental impacts from an
accident would be insignificant.
There are no changes to cask design or fabrication requirements in
the renewed initial certificate or Amendment No. 1. Because there are
no significant design or process changes, any resulting occupational
exposure or offsite dose rates from the implementation of the renewal
of the initial certificate and Amendment No. 1 would remain well within
the 10 CFR part 20 limits.
In summary, the proposed changes will not result in any
radiological or nonradiological environmental impacts that
significantly differ from the environmental impacts evaluated in the
environmental assessment supporting the July 18, 1990, final rule.
Compliance with the requirements of 10 CFR parts 20 and 72 would
provide reasonable assurance that adequate protection of public health
and safety will continue. The NRC, in its SER for the renewal of the
TN-32 Dry Storage Cask system, has determined if the conditions
specified in the certificate of compliance to implement these
regulations are met, adequate protection of public health and safety
will continue to be reasonably assured.
Based on the previously stated assessments and its SER for the
requested renewal of the TN-32 Dry Storage Cask certificates, the NRC
has determined that the expiration date of this system in 10 CFR 72.214
can be safely extended for an additional 40 years, and that commercial
nuclear power reactor licensees can continue using the system during
this period under a general license without significant impacts on the
human environment.
D. Alternative to the Action
The alternative to this action is to deny approval of the renewal
and not issue the direct final rule. Under this alternative, the NRC
would either (1) require general licensees using the TN-32 Dry Storage
Cask to unload the spent fuel from these systems and either return it
to a spent fuel pool or reload it into a different dry storage cask
system listed in Sec. 72.214; or (2) require that users of the
existing TN-32 Dry Storage Cask request site-specific licensing
proceedings to continue storage in these systems.
[[Page 61051]]
The environmental impacts of requiring the licensee to unload the
spent fuel and either return it to the spent fuel pool or re-load it
into another NRC-approved cask system would result in increased
radiological doses to workers. These increased doses would be due
primarily to direct radiation from the casks while the workers
unloaded, transferred, and re-loaded the spent fuel. These activities
would consist of transferring the dry storage canisters to a cask-
handling building, opening the canister lid welds, returning the
canister to a spent fuel pool or dry transfer facility, removing the
fuel assemblies, and re-loading them, either into a spent fuel pool
storage rack or another NRC-approved dry storage system. In addition to
the increased occupational doses to workers, these activities may also
result in additional liquid or gaseous effluents.
Alternatively, users of the dry cask storage system would need to
apply for a site-specific license. Under this option for implementing
the no-action alternative, interested licensees would have to prepare,
and the NRC would have to review, each separate license application,
thereby increasing the administrative burden upon the NRC and the costs
to each licensee.
In summary, the no-action alternative would entail either (1) more
environmental impacts than the preferred action from transferring the
spent fuel now in the TN-32 Dry Storage Cask; or (2) cost and
administrative impacts from multiple licensing actions that, in
aggregate, are likely to be the same as, or more likely greater than,
the preferred action.
E. Alternative Use of Resources
Renewal of the initial certificate and Amendment No. 1 to
Certificate of Compliance No. 1021 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: TN Americas LLC, TN-32 Dry Storage
Cask, Certificate of Compliance No. 1021, Renewal of Initial
Certificate and Amendment No. 1,'' 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
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).
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
March 20, 2000 (65 FR 14790), the NRC issued an amendment to 10 CFR
part 72, with an effective date of April 19, 2000, that approved the TN
Americas LLC TN-32 Dry Storage Cask by adding it to the list of NRC-
approved cask designs in Sec. 72.214.
On March 5, 2020, and as supplemented on November 11, 2020;
February 5, 2021; and March 17, 2021, TN Americas LLC requested a
renewal of the initial certificate and Amendment No. 1 of the TN-32 Dry
Storage Cask system for an additional 40 years beyond the initial
certificate term as discussed in Section IV, ``Discussion of Changes,''
of this document. Because TN Americas LLC filed its renewal application
at least 30 days before the certificate expiration date of April 19,
2020, pursuant to the timely renewal provisions in Sec. 72.240(b), the
initial issuance of the certificate and Amendment No. 1 of Certificate
of Compliance No. 1021 did not expire.
The alternative to this action is to deny approval of the renewal
of the initial certificate and Amendment No. 1 of Certificate of
Compliance No. 1021 and end this direct final rule. Under this
alternative, the NRC would either (1) require general licensees using
the TN-32 Dry Storage Cask system to unload spent fuel from these
systems and return it to a spent fuel pool or reload it into a
different dry storage cask system listed in Sec. 72.214, or (2)
require that users of the existing TN-32 Dry Storage Cask system
request site-specific licensing proceedings to continue storage in
these systems. Therefore, the no-action alternative would result in a
significant burden on licensees and an additional inspection or
licensing caseload on the NRC. In addition, the no-action alternative
would entail either (1) more environmental impacts than the preferred
action from transferring the spent fuel now in the TN-32 Dry Storage
Cask system, or (2) cost and administrative impacts from multiple
licensing actions that, in aggregate, are likely to be the same as, or
more likely greater than, the preferred action.
Approval of this direct final rule is consistent with previous NRC
actions. Further, as documented in the preliminary SER 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
The NRC has determined that the backfit rule (Sec. 72.62) does not
apply to
[[Page 61052]]
this direct final rule. Therefore, a backfit analysis is not required.
This direct final rule renews Certificate of Compliance No. 1021 for
the TN Americas LLC TN-32 Dry Storage Cask system, as currently listed
in Sec. 72.214, to extend the expiration date of the initial
certificate and Amendment No. 1 by 40 years. The renewed initial
certificate and Amendment No. 1 consist of the changes previously
described, as set forth in the revised certificate of compliance and
technical specifications.
Extending the effective date of the initial certificate and
Amendment No. 1 for 40 more years and requiring the implementation of
aging management activities does not impose any modification or
addition to the design of a cask system's SSCs, or to the procedures or
organization required to operate the system during the initial 20-year
storage period of the system, as authorized by the current certificate.
General licensees that have loaded these casks, or that load these
casks in the future under the specifications of the applicable
certificate, may continue to store spent fuel in these systems for the
initial 20-year storage period consistent with the original
certificate. The aging management activities required to be implemented
by this renewal are only required after the storage cask system's
initial 20-year service period ends. As explained in the 2011 final
rule that amended 10 CFR part 72 (76 FR 8872, Question I), the general
licensee's authority to use a particular storage cask design under an
approved certificate of compliance terminates 20 years after the date
that the general licensee first loads the particular cask with spent
fuel, unless the cask's certificate of compliance is renewed. Because
this rulemaking renews the initial certificate and Amendment No. 1, and
renewal is a separate licensing action voluntarily implemented by
vendors, the renewal of the initial certificate and Amendment No. 1 is
not an imposition of new or changed requirements from which these
licensees would otherwise be protected by the backfitting provisions in
Sec. 72.62.
Even if renewal of the initial certificate and Amendment No. 1 of
Certificate of Compliance No. 1021 could be considered a backfit, TN
Americas LLC, as the holder of the certificate of compliance and vendor
of the casks, is not protected by the backfitting provisions in Sec.
72.62.
Unlike a vendor, general licensees using the existing systems
subject to this renewal would be protected by the backfitting
provisions in Sec. 72.62 if the renewal constituted new or changed
requirements applicable during the initial 20-year storage period. But,
as previously explained, renewal of the initial certificate and
Amendment No. 1 of Certificate of Compliance No. 1021 does not impose
such requirements. The general licensee using the initial certificate
or Amendment No. 1 of Certificate of Compliance No. 1021 may continue
storing material in its respective cask systems for the initial 20-year
storage period identified in the applicable certificate or amendment
with no changes. If general licensees choose to continue to store spent
fuel in the TN-32 Dry Storage Cask system after the initial 20-year
period, these general licensees will be required to implement aging
management activities for any cask systems subject to a renewed
certificate of compliance, but such continued use is voluntary.
For these reasons, renewing the initial certificate and Amendment
No. 1 of Certificate of Compliance No. 1021, and imposing the
additional conditions previously discussed, 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.
