SUMMARY
- The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of
an exemption in response to the May 4, 2023, request from Yankee Atomic Electric
Company (YAEC), for the Yankee Nuclear Power Station (YNPS or Yankee Rowe)
located in Rowe, Massachusetts. The proposed exemption from NRC regulations, if
granted, would permit YAE C to make withdrawals from a segregated account within
Yankee Rowes overall nuclear decommissioning trust (NDT), on an annual basis, for
spent nuclear fuel (SNF) and Greater than Class C (GTCC) waste management and
non-radiological site restoration without prior notification to the NRC. The NRC staff is
issuing an environmental assessment (EA) and finding of no significant impact (FONSI)
associated with the proposed exemption.

SUPPLEMENTARY INFORMATION:
I. Introduction
By letter dated May 4, 2023, Yankee Atomic Electric Company (YAEC or the
licensee) submitted a request to the NRC for an exemption from paragraphs
50.82(a)(8)(i)(A) and 50.75(h)(2) of t itle 10 of the Code of Federal Regulations (10 CFR)
2 for the Yankee Rowe Independent Spent Fuel Storage Installation1 (ISFSI).
YAEC has established a separate (segregated) account within its over-arching
nuclear decommissioning trust (NDT), entitled ISFSI Radiological Decom, that
identifies the funds for radiological decommissioning of the ISFSI apart from the larger
balance of funds in the NDT allocated for ongoing management of SNF and GTCC
waste and for non-radiological site restoration activities. Although 10 CFR 50.82 applies
to the segregated account, it does not apply to the overall NDT.
If granted, the exemptions from 10 CFR 50.82(a)(8)(i)(A) and 50.75(h)(2) would
permit YAEC to make withdrawals from the segregated account, on an annual basis, for
SNF and GTCC waste management and non-radiological site restoration without prior
notification to the NRC. More specifically, with this exemption, YAEC would be able to
annually transfer funds exceeding 110 percent of the inflation-adjusted decommissioning
cost estimate, described in 10 CFR 50.75, from the segregated account to its
overarching NDT and use those funds for SNF and GTCC waste management and non-
radiological site restoration.
YAEC received an operating license from the NRC in December 1963, and
Yankee Rowe was permanently shut down in October 1991. In 1993, YAEC commenced
decommissioning the power plant. The licensee constructed an onsite ISFSI under a
general license and transferred the last canister containing GTCC material to the ISFSI
in June 2003. The plant completed its final decommissioning of the reactor site, except
for the ISFSI, which included dismantling and removing all reactor plant related facilities,
1 As discussed in this document, the Yankee Rowe ISFSI sits on the former site of Yankee Rowe, which YAEC finished decommissioning in 2007. Although only the Yankee Rowe ISFSI remains on the site, YAECs 10 CFR part 50 license, Facility Operating License No. DPR -3 remains in effect. Because YAEC requested an exemption from the requirements of 10 CFR p art 50, this would be an exemption for YAECs 10 CFR p art 50 license rather than for YAECs 10 CFR part 72 general license. Therefore, although YAEC s submission requested an exemption for the Yankee Rowe ISFSI, the NRC staff will consider it a request for an exemption for YNPS.
3 in 2007. As a result, only the ISFSI remains at the old plant site of YNPS in Rowe,
Massachusetts. By letter dated August 10, 2007, NRC approved the release of the
majority of the YNPS site from the 10 CFR part 50 license (DPR-3) for unrestricted
release, except for the ISFSI and immediately surrounding areas. Under its
10 CFR part 72 general license, YAEC is authorized to possess, and store spent nuclear
fuel at the permanently shut down and decommissioned facility under the provision of
10 CFR part 72, su bpart K, General License for Storage of Spent Fuel at Power
Reactor Sites.
The NRC staff is performing both a safety evaluation and an environmental
review to determine whether to grant this exemption request. The NRC staff will prepare
a separate safety evaluation report (SER) to document its safety review and analysis.
The NRCs SER will evaluate the proposed exemption for reasonable assurance of
adequate protection of public health and safety, and the common defense and security.
This EA documents the environmental review which the NRC staff prepared in
accordance with 10 CFR 51.21 and 51.30(a). The NRCs decision whether to grant the
exemption will be based on the results of the NRC staffs review as documented in this
EA, and the staffs safety review to be documented in the SER.
II. Environmental Assessment
By letter dated May 4, 2023, YAEC submitted a request to the NRC for an
exemption from 10 CFR 50.82(a)(8)(i)(A) and 10 CFR 50.75(h)(2). If granted, the
proposed exemption from 10 CFR 50.82(a)(8)(i)(A) and 50.75(h)(2) would permit YAEC
to make withdrawals from the segregated account, on an annual basis, for SNF and
GTCC waste management and non-radiological site restoration without prior notification
to the NRC. More specifically, with this exemption, YAEC would be able to annually
transfer funds exceeding 110 percent of the inflation -adjusted decommissioning cost
4 estimate (DCE), described in 10 CFR 50.75, from the segregated account to its
overarching NDT and use those funds for SNF and GTCC waste management and
non-radiological site restoration activities.
Need for the Proposed Action
As required by 10 CFR 50.82(a)(8)(i)(A), decommissioning trust funds may be
used by the licensee if the withdrawals are for legitimate decommissioning activity
expenses, consistent with the definition of decommissioning in 10 CFR 50.2. This
definition addresses radiological decommissioning and does not include activities
associated with management of SNF and GTCC waste or non-radiological site
restoration. Similarly, the requirements of 10 CFR 50.75(h)(2) restrict the use of
decommissioning trust fund disbursements (other than for ordinary and incidental
expenses) to decommissioning expenses until final decommissioning has been
completed.
YAEC stated that it has established a segregated account, entitled ISFSI
Radiological Decom, within its over-arching NDT, that identifies the funds for
radiological decommissioning of the ISFSI. This segregated account is separate from the
larger balance of funds in the NDT allocated for ongoing management of SNF and
GTCC waste and for other non-radiological site restoration activities. Therefore,
exemption from 10 CFR 50.82(a)(8)(i)(A) and 50.75(h)(2) is needed to allow YAEC to
use funds from the segregated account for SNF and GTCC waste management and
other non-radiological site restoration activities.
In its Decommissioning Funding Assurance Status Report dated March 6, 2023,
YAEC stated that its inflation-adjusted DCE for the radiological decommissioning of the
ISFSI, is approximately $6.1 million in 2022 dollars. It asserted this amount provides
reasonable assurance of adequate funding to complete the NRC required
5 decommissioning activities. In the same report, YAEC reported that, as of
December 31, 2022, the segregated ISFSI Radiological Decom account had $22.5
million. More specifically, in its exemption request, YAEC provided a table showing
$6,087,475, in 2022 dollars, as the inflation-adjusted DCE. YAECs exemption request
further stated that the segregated account has a balance of $22,496,631 as of
December 31, 2022, meaning that the segregated account had a balance of
$16,409,156, or 270 percent beyond the inflation-adjusted DCE.
YAEC stated that, if the exemption is granted, funds in its segregated account
which exceed 110 percent of the inflation-adjusted DCE for the radiological
decommissioning of the ISFSI would be transferred to the overarching NDT on an
annual basis without prior NRC notification. YAEC would then use those funds for SNF
and GTCC waste management and non-radiological site restoration, which in turn, would
allow YAEC to return its additional excess funds in the overarching NDT to its customers
as part of future rate cases with the Federal Energy Regulatory Commission.
The requirements of 10 CFR 50.75(h)(2) further provide that, except for
withdrawals being made under 10 CFR 50.82(a)(8) or for payments of ordinary
administrative costs and other incidental expenses of the NDT in connection with the
operation of the NDT, no disbursement may be made from the NDT without written
notice to the NRC at least 30 working days in advance. Therefore, an exemption from
10 CFR 50.75(h)(2) is also needed to allow YAEC to use funds from the segregated
account for SNF and GTCC waste management and non-radiological site restoration
activities without prior NRC notification.
Environmental Impacts of the Proposed Action
The proposed action involves an exemption from requirements that are of
financial and/or administrative nature and that do not have an impact on the
6 environment. Before the NRC could approve the proposed action, it would have to
conclude that there is reasonable assurance that adequate funds are available in the
segregated account to complete all activities associated with radiological
decommissioning as well as SNF and GTCC waste management and non-radiological
site restoration. Therefore, there would be no decrease in safety associated with the use
of funds from the segregated account to also fund activities associated with SNF and
GTCC waste management and non-radiological site-restoration.
The requested exemption from the requirements of 10 CFR 50.82(a)(8)(i)(A) and
10 CFR 50.75(h)(2), if approved, would allow transfers on an annual basis. YAEC stated
that it will continue to provide its annual decommissioning funding assurance status
report in accordance with 10 CFR 50.75(f)(1) and (2) and 10 CFR 50.82(a)(8)(v) and (vi)
requirements. These reports provide the NRC staff with awareness of, and the ability to
act on, any actual or potential funding deficiencies. As the proposed exemption would
not affect these requirements, the NRC staff would have tools available for any potential
funding deficiencies. Since the exemption would allow YAEC to use funds from the
segregated account that are in excess of those required for radiological
decommissioning, the adequacy of funds dedicated for radiological decommissioning
would not be affected by the proposed exemption. Therefore, there is reasonable
assurance that there would be no environmental impact due to lack of adequate funding
for radiological decommissioning.
Further, there are no new accident precursors created by using the excess funds
from the segregated account for SNF and GTCC waste management and
non-radiological site-restoration. The exemption, if granted, would be financial and/or
administrative in nature. Thus, the probability of postulated accidents is not increased.
Also, the consequences of postulated accidents are not increased. No changes are
7 being made in the types or amounts of effluents that may be released offsite. There is no
significant increase in occupational or public radiation exposure. Therefore, the
requested exemption will not present an undue risk to the public health and safety.
With regard to potential non-radiological impacts, the proposed action would
have no direct impacts on land use or water resources, including terrestrial and aquatic
biota, as it involves no new construction or modification of plant operational systems.
There would be no changes to the quality or quantity of non-radiological effluents. In
addition, there would be no noticeable effect on socioeconomic conditions in the region,
no environmental justice impacts, no air quality impacts, and no impacts to historic and
cultural resources from the proposed action. Therefore, there are no significant
non-radiological environmental impacts associated with the proposed action.
For these reasons, the NRC concludes there are no significant environmental
impacts associated with the proposed exemption request.
Environmental Impacts of the Alternatives to the Proposed Action
In addition to the proposed action, the NRC staff also considered denial of the
proposed action (i.e., the no -action alternative). Denial of the exemption request would
result in no change in current environmental impacts. The environmental impacts of the
proposed action and the alternative action would be similar.
Alternative Use of Resources
There are no unresolved conflicts concerning alternative uses of available
resources under the proposed action.
Agencies Consulted
By email dated February 16, 2024, the NRC provided a copy of the draft EA to
the Massachusetts Department of Public Health, Radiation Control Program, Bureau of
Environmental Health, for review. By email dated March 14, 2024, Massachusetts
8 Department of Public Health, Radiation Control Program, Bureau of Environmental
Health indicated that it had no comments.
Endangered Species Act Section 7 Consultation
Section 7 of the Endangered Species Act of 1973, as amended (ESA), requires
Federal agencies to consult with the U.S. Fish and Wildlife Service or National Marine
Fisheries Service regarding actions that may affect listed species or designated critical
habitats. The ESA is intended to prevent further decline of endangered and threatened
species and restore those species and their critical habitat.
The NRC staff determined that a consultation under section 7 of the ESA is not
required because the proposed action will not affect listed species or critical habitat.
National Historic Preservation Act Section 106 Consultation
Section 106 of the National Historic Preservation Act (NHPA) requires Federal
agencies to consider the effects of their undertakings on historic properties. As stated in
the NHPA, historic properties are any prehistoric or historic district, site, building,
structure, or object included in, or eligible for inclusion in the National Register of Historic
Places.
The NRC determined that the scope of activities described in this exemption
request do not have the potential to cause effects on historic properties because the
NRCs approval of this exemption request will not authorize new construction or land
disturbance activities. The NRC staff also determined that the proposed action is not a
type of activity that has the potential to impact historic properties because the proposed
action would occur within the established Yankee Rowe site boundary. Therefore, in
accordance with 36 CFR 800.3(a)(1), no consultation is required under section 106 of
NHPA.
9 III. Finding of No Significant Impact
The environmental impacts of the proposed action an exemption from the
requirements of 10 CFR 50.82(a)(8)(i)(A) and 10 CFR 50.75(h)(2) allowing YAEC to
make withdrawals from the segregated account, on an annual basis, for SNF and GTCC
waste management and non- -radiological site restoration without prior notification to the
NRC have been reviewed under the requirements in 10 CFR p art 51, which
implement the National Environmental Policy Act of 1969, as amended.
The proposed exemption would not have a significant adverse effect on the
probability of an accident occurring and would not have any significant radiological or
non-radiological impacts. The proposed exemption involves an exemption from
requirements that are of a financial and/or administrative nature and would not have an
impact on the human environment. Consistent with 10 CFR 51.21, the NRC conducted
the EA for the proposed exemption, and this FONSI incorporates by reference the EA
included in this document. Therefore, the NRC concludes that the proposed action will
not have significant effects on the quality of the human environment. Accordingly, the
NRC has determined not to prepare an environmental impact statement for the proposed
action.
