Palo Verde Nuclear Generating
Station began operation in 1986 and has
been storing pressurized-water reactor
spent fuel in its independent spent fuel
storage installation since March 2003
utilizing Certificate of Compliance No.
1015 for the NAC–UMS storage system.
For the loading campaign commencing
in August 2019, Arizona Public Service
Company is transitioning to the
MAGNASTOR® storage system,
Certificate of Compliance No. 1031,
Amendment No. 7 (ADAMS Package
Accession No. ML17013A466). The
majority of the spent fuel assemblies to
be loaded in the upcoming loading
campaign have pellets with a maximum
diameter of 0.3255 inches (0.8268
centimeters). While the NAC–UMS
system was approved for this pellet
diameter in Amendment No. 2 to CoC
No. 1015 (ADAMS Package Accession
No. ML020250546), the MAGNASTOR®
storage system is approved for the
nominal pellet diameter of 0.325 inches
(0.8255 centimeters), thereby precluding
some of the spent fuel at the Palo Verde
Nuclear Generating Station from being
loaded in the upcoming loading
campaign.
II. Request/Action
By application dated July 5, 2019
(ADAMS Accession No. ML19186A449),
Arizona Public Service Company
submitted a request for an exemption
from those provisions of title 10 of the
Code of Federal Regulations (10 CFR)
72.212(a)(2), 72.212(b)(3),
72.212(b)(5)(i), 72.212(b)(11), and
72.214 that require compliance with the
terms, conditions, and specifications of
Certificate of Compliance No. 1031,
Amendment No. 7, for the Palo Verde
Nuclear Generating Station to load spent
fuel with a maximum pellet diameter of
0.3255 inches (0.8268 centimeters),
utilizing Amendment No. 7 for the NAC

system.
III. Discussion
Pursuant to 10 CFR 72.7, the
Commission may, upon application by
any interested person or upon its own
initiative, grant such exemptions from
the requirements of the regulations of 10
CFR part 72 as it determines are
authorized by law and will not endanger
life or property or the common defense
and security, and are otherwise in the
public interest.
The NRC staff prepared a safety
evaluation report (ADAMS Accession
No. ML19213A033) to document the
safety evaluation of the proposed action
(i.e., exemption to authorize loading
spent fuel with a maximum pellet
diameter of 0.3255 inches (0.8268
centimeters)), to assure that the
exemption is authorized by law, will
protect life or property or the common
defense and security and are otherwise
in the public interest. As summarized in
this document, the NRC’s safety review
concludes that the requested exemption
meets the requirements for issuance in
10 CFR 72.7.
A. The Exemption is Authorized by Law
This exemption would permit the
Palo Verde Nuclear Generating Station
to load spent fuel with a larger pellet
diameter than authorized in Certificate
of Compliance No. 1031, Amendment
No. 7.
Section 72.7 allows the Commission
to grant exemptions from the
requirements of 10 CFR part 72 if the
exemption is authorized by law and will
not endanger life or property nor the
common defense and security. Issuance
of this exemption is consistent with the
Atomic Energy Act of 1954, as amended,
and not otherwise inconsistent with
NRC’s regulations or other applicable
laws. Therefore, issuance of the
exemption is authorized by law.

B. Will Not Endanger Life or Property or
the Common Defense and Security
As discussed in the safety evaluation
report and summarized in the following
sections, the NRC staff has found that
Arizona Public Service Company’s
proposed action is acceptable and will
not endanger life or property or the
common defense and security.
Safety Review of the Requested
Exemption
The staff reviewed the exemption
request for Palo Verde Nuclear
Generating Station and concludes, as
discussed in this document, that the
proposed exemption from certain
requirements of 10 CFR part 72 will not
VerDate Sep<11>2014
17:00 Aug 28, 2019
Jkt 247001
cause the MAGNASTOR® storage cask
to encounter conditions beyond those
for which it has been evaluated and
demonstrated to meet the applicable
safety requirements in 10 CFR part 72.
As explained in this document, the
staff’s evaluation includes only the
criticality safety area of review, since it
is the only technical area revised by this
exemption.
The licensee submitted an exemption
request to deviate from the maximum
pellet diameter for Combustion
Engineering 16×16 fuel, stored in the
NAC MAGNASTOR® dry storage
system. The licensee stated that NAC
International evaluated a pellet diameter
of 0.3255 inches (0.8268 centimeters) in
the MAGNASTOR® final safety analysis
report (ADAMS Accession No.
ML091030364), to determine the effect
of an upper manufacturing tolerance of
0.0005 inches (0.0013 centimeters)
applied to the nominal value of 0.3250
inches (0.8255 centimeters). In that final
safety analysis report, NAC
International determined that the
system k-effective with this larger
diameter pellet is statistically the same
as the system k-effective with the
nominal pellet diameter. Therefore,
Arizona Public Service Company stated
that its proposed exemption has no
effect on the criticality safety of the
MAGNASTOR® storage system.
The staff reviewed the final safety
analysis report and agrees that the
proposed change to the pellet diameter
will not result in changes to system keffective that are statistically significant.
The staff also agrees that the results of
the NAC International criticality
analysis, and with the licensee’s
conclusion that this proposed
exemption does not affect the ability of
the MAGNASTOR® system to meet the
criticality safety requirements of 10 CFR
part 72.
Based on these evaluations, the staff
has concluded that granting this
exemption will be consistent with the
requirements of 10 CFR part 72 and will
not endanger life or property.
Review of Common Defense and
Security: Modification of the pellet
diameter does not affect the
independent spent fuel storage
installation security plans. Accordingly,
the Palo Verde Nuclear Generating
Station independent spent fuel storage
installation will continue to be
physically protected under Arizona
Public Service Company’s independent
spent fuel storage installation Physical
Security Plan to the same level of
security.
Based on its review, the NRC staff has
determined that under the requested
exemption, the storage system will
PO 00000
Frm 00091
Fmt 4703
Sfmt 4703
45553
continue to meet the safety
requirements of 10 CFR part 72 and the
offsite dose limits of 10 CFR part 20
and, therefore, will not endanger life or
property. The NRC staff also found that
the exemption would not endanger
common defense and security.
D. Otherwise in the Public Interest
In determining whether the
exemption is in the public interest, the
staff considered the no-action
alternative of denying the exemption
request. Denial of the exemption request
would cause Arizona Public Service
Company to postpone loading of spent
fuel that contains the larger pellet
diameter until it is approved in an
amendment for CoC No. 1031 or
alternative loading arrangements are
implemented.
The licensee stated that the proposed
exemption is in the public interest
because it would allow Arizona Public
Service Company to load spent fuel on
schedule, maintain full-core offload
capability and would not affect power
plant operations or refueling outages for
the three units at the Palo Verde Nuclear
Generating Station.
E. Environmental Considerations
The NRC staff also considered
whether there would be any significant
environmental impacts associated with
the exemption. For this proposed action,
the NRC staff performed an
environmental assessment pursuant to
10 CFR 51.30. The environmental
assessment concluded that the proposed
action would not significantly impact
the quality of the human environment.
The NRC staff concluded that the
proposed action would not result in any
changes in the types or amounts of any
radiological or non-radiological
effluents that may be released offsite,
and there is no significant increase in
occupational or public radiation
exposure because of the proposed
action. The environmental assessment
and the finding of no significant impact
was published on August 23, 2019 (84
FR 44339).
IV. Conclusion
Accordingly, the Commission has
determined that, pursuant to 10 CFR
72.7, this exemption is authorized by
law, will not endanger life or property
or the common defense and security,
and is otherwise in the public interest.
Therefore, the Commission hereby
grants Arizona Public Service Company
an exemption from those provisions of
10 CFR 72.212(a)(2), 10 CFR
72.212(b)(3), 10 CFR 72.212(b)(5)(i), 10
CFR 72.214, and the portion of 10 CFR
72.212(b)(11) that require compliance

Commission.
ACTION: Order; issuance.
AGENCY:
The U.S. Nuclear Regulatory
Commission (NRC) is issuing an Order
suspending the license of APINDE Inc.
(APINDE) located in Huntington, West
Virginia. The NRC has determined that
this action is necessary based on an
ongoing review of the circumstances
through which APINDE obtained and
subsequently used its NRC license for
industrial radiography. Specifically, the
NRC has determined that APINDE
submitted inaccurate information in its
initial license application pertaining to
the qualifications for an individual
proposed to be the Radiation Safety
Officer (RSO). This resulted in the NRC
issuing a license to the company that
was, in part, based on the inaccurate
information and in APINDE maintaining
an industrial radiography license
without a qualified RSO. Further, after
the initial RSO resigned, and APINDE
submitted an application to amend the
license and name a new RSO, the
company submitted inaccurate
information pertaining to that
individual. Moreover, the NRC has
information indicating that APINDE
used its NRC license to procure a sealed
radiography source, and may have
allowed unauthorized access to the
source.
As a result, the NRC has lost
assurance that APINDE can conduct the

compliance with NRC regulations and
will protect the health and safety of the
public. In accordance with the Order,
APINDE must immediately cease all
radiographic operations and return any
byproduct material possessed under the
license to locked, safe storage. APINDE
shall not receive any NRC-licensed
material while the Order is in effect.
APINDE must respond to the Order

International MAGNASTOR[supreg] storage system.
III. Discussion
Pursuant to 10 CFR 72.7, the Commission may, upon application by
any interested person or upon its own initiative, grant such exemptions
from the requirements of the regulations of 10 CFR part 72 as it
determines are authorized by law and will not endanger life or property
or the common defense and security, and are otherwise in the public

Safety Review of the Requested Exemption
The staff reviewed the exemption request for Palo Verde Nuclear
Generating Station and concludes, as discussed in this document, that
the proposed exemption from certain requirements of 10 CFR part 72 will
not cause the MAGNASTOR[supreg] storage cask to encounter conditions
beyond those for which it has been evaluated and demonstrated to meet
the applicable safety requirements in 10 CFR part 72. As explained in
this document, the staff's evaluation includes only the criticality
safety area of review, since it is the only technical area revised by
this exemption.
The licensee submitted an exemption request to deviate from the
maximum pellet diameter for Combustion Engineering 16x16 fuel, stored
in the NAC MAGNASTOR[supreg] dry storage system. The licensee stated
that NAC International evaluated a pellet diameter of 0.3255 inches
(0.8268 centimeters) in the MAGNASTOR[supreg] final safety analysis
report (ADAMS Accession No. ML091030364), to determine the effect of an
upper manufacturing tolerance of 0.0005 inches (0.0013 centimeters)
applied to the nominal value of 0.3250 inches (0.8255 centimeters). In
that final safety analysis report, NAC International determined that
the system k-effective with this larger diameter pellet is
statistically the same as the system k-effective with the nominal
pellet diameter. Therefore, Arizona Public Service Company stated that
its proposed exemption has no effect on the criticality safety of the
MAGNASTOR[supreg] storage system.
The staff reviewed the final safety analysis report and agrees that
the proposed change to the pellet diameter will not result in changes
to system k-effective that are statistically significant. The staff
also agrees that the results of the NAC International criticality
analysis, and with the licensee's conclusion that this proposed
exemption does not affect the ability of the MAGNASTOR[supreg] system
to meet the criticality safety requirements of 10 CFR part 72.
Based on these evaluations, the staff has concluded that granting
this exemption will be consistent with the requirements of 10 CFR part
72 and will not endanger life or property.
Review of Common Defense and Security: Modification of the pellet
diameter does not affect the independent spent fuel storage
installation security plans. Accordingly, the Palo Verde Nuclear
Generating Station independent spent fuel storage installation will
continue to be physically protected under Arizona Public Service
Company's independent spent fuel storage installation Physical Security
Plan to the same level of security.
Based on its review, the NRC staff has determined that under the
requested exemption, the storage system will continue to meet the
safety requirements of 10 CFR part 72 and the offsite dose limits of 10
CFR part 20 and, therefore, will not endanger life or property. The NRC
staff also found that the exemption would not endanger common defense
and security.
D. Otherwise in the Public Interest
In determining whether the exemption is in the public interest, the
staff considered the no-action alternative of denying the exemption
request. Denial of the exemption request would cause Arizona Public
Service Company to postpone loading of spent fuel that contains the
larger pellet diameter until it is approved in an amendment for CoC No.
1031 or alternative loading arrangements are implemented.
The licensee stated that the proposed exemption is in the public
interest because it would allow Arizona Public Service Company to load
spent fuel on schedule, maintain full-core offload capability and would
not affect power plant operations or refueling outages for the three
units at the Palo Verde Nuclear Generating Station.
E. Environmental Considerations
The NRC staff also considered whether there would be any
significant environmental impacts associated with the exemption. For
this proposed action, the NRC staff performed an environmental
assessment pursuant to 10 CFR 51.30. The environmental assessment
concluded that the proposed action would not significantly impact the
quality of the human environment. The NRC staff concluded that the
proposed action would not result in any changes in the types or amounts
of any radiological or non-radiological effluents that may be released
offsite, and there is no significant increase in occupational or public
radiation exposure because of the proposed action. The environmental
assessment and the finding of no significant impact was published on
August 23, 2019 (84 FR 44339).
IV. Conclusion
Accordingly, the Commission has determined that, pursuant to 10 CFR
72.7, this exemption is authorized by law, will not endanger life or
property or the common defense and security, and is otherwise in the
public interest. Therefore, the Commission hereby grants Arizona Public
Service Company an exemption from those provisions of 10 CFR
72.212(a)(2), 10 CFR 72.212(b)(3), 10 CFR 72.212(b)(5)(i), 10 CFR
72.214, and the portion of 10 CFR 72.212(b)(11) that require compliance
[[Page 45554]]
with terms, conditions, and specifications of the Certificate of
Compliance No. 1031, Amendment No. 7, for the Palo Verde Nuclear
Generating Station to load spent fuel with a maximum pellet diameter of
0.3255 inches (0.8268 centimeters) in the MAGNASTOR[supreg] storage
system using Certificate of Compliance No. 1031, Amendment No. 7.
The exemption is effective upon issuance.
