NUCLEAR REGULATORY COMMISSION
[Docket No. 72-17; NRC-2020-0238]
Portland General Electric Company; Trojan Independent Spent Fuel
Storage Installation
AGENCY: Nuclear Regulatory Commission.
ACTION: Environmental assessment and finding of no significant impact;
issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is considering an
amendment request from Portland General Electric Company (PGE) to amend
License No. SNM-2509 for the Trojan Independent Spent Fuel Storage
Installation (ISFSI), located in Columbia County, Oregon. The amendment
would revise the safety analysis report (SAR) description of the
licensee's evaluation of explosion accident events. As part of its
review, the NRC performed an environmental assessment (EA) of the
proposed action. The NRC concluded that the proposed action would have
no significant environmental impact. Accordingly, the NRC staff is
issuing a finding of no significant impact (FONSI) associated with the
proposed amendment.
DATES: The EA and FONSI referenced in this document became available on
November 16, 2020.

SUPPLEMENTARY INFORMATION:
I. Introduction
In August 2012, the U.S. Army Corps of Engineers installed an
anchor buoy for a new Prescott Anchorage Area on the Columbia River
just outside the Trojan ISFSI Controlled Area Boundary. During a 2015
inspection, an NRC inspector questioned if the supporting analyses for
Trojan Final Safety Analysis Report (FSAR) Sections 2.2.3.1
``Explosions'' and Section 8.2.8 ``Explosions of Chemicals, Flammable
Gasses, and Munitions'' remained bounding due to the new anchorage. To
address this issue, PGE reviewed the Trojan FSAR explosion event
evaluation description, and concluded that certain statements
pertaining to the deterministic evaluation of the design basis
explosion event could not be confirmed. Therefore, PGE commissioned a
comprehensive new evaluation of potential impacts on the Trojan ISFSI
due to explosion events from both rail and waterborne vessel traffic.
The evaluation also accounted for waterborne vessels periodically
moored at the new Prescott Anchorage Area.
PGE submitted a license amendment application to update the Trojan
FSAR evaluation of explosion accident events originating from cargo
transported by rail and waterborne vessels that could potentially
affect the ISFSI and requested NRC approval of the subject FSAR change.
The NRC is reviewing the amendment request from PGE dated March 10,
2020 (ADAMS Package Accession No. ML20083G798).
II. Environmental Assessment Summary
Under the requirements of sections 51.21 and 51.30(a) of title10 of
the Code of Federal Regulations (10 CFR), the NRC staff developed an EA
(ADAMS Accession No. ML20287A234) to evaluate the proposed action,
which is for the NRC to approve the PGE amendment request to revise the
SAR description of the licensee's evaluation of explosion accident
events.
The EA defines the NRC's proposed action (i.e., to approve the
amendment request) as well as the purpose of and the need for the
proposed action. The EA evaluates the potential environmental impacts
of approving the amendment to update the Trojan FSAR evaluation of
explosion accident events originating from cargo transported by rail
and waterborne vessels that could potentially affect the ISFSI. The EA
also provides the NRC's conclusion.
The NRC staff finds that the environmental effects from this
amendment request are bounded by the environmental impacts discussed in
the June 26, 2019 EA for renewal of the Trojan ISFSI license. That EA
found that continued operation of the Trojan ISFSI for an additional 40
years will not significantly affect the quality of the environment
(ML19058A264). The NRC staff finds that the environmental impacts from
PGE's amendment request are bounded by the previous EA for the
following reasons. First, PGE's requested amendment involves no changes
to the ISFSI design or operation. Second, the SAR revision is limited
to adding a more comprehensive evaluation of offsite explosion events.
Third, the evaluation results remain the same. The new evaluation
concludes, consistent with the prior evaluation, that offsite
explosions would not have radiological consequences.
Because the evaluation results, the ISFSI design, and the ISFSI
operation remain unchanged, the proposed action does not change the
types or quantities of effluents that may be released offsite, and it
does not increase occupational or public radiation exposure. Therefore,
there are no significant radiological environmental impacts associated
with the proposed action. There is no change to non-radiological
effluents because the proposed action only requires revising the FSAR
and does not have other environmental impacts. Thus, the proposed
action will not have a significant effect on the quality of the human
environment and the environmental impacts of the proposed action are no
greater than those described in the EA for renewal of SNM-2509.
Agencies and Persons Consulted
The NRC provided the Oregon Health Authority a draft copy of the EA
for review in an email dated August 27, 2020 (ADAMS Accession No.
ML20244A153). The NRC staff has determined that this amendment would
[[Page 73299]]
have no impact on historic and cultural resources or ecological
resources. Consequently, no consultations are necessary under Section
106 of the National Historic Preservation Act or Section 7 of the
Endangered Species Act.
III. Finding of No Significant Impact
Based on its review of the proposed action in the EA, in accordance
with the requirements in 10 CFR part 51, the NRC staff has concluded
that the proposed action, approval of the requested amendment, will not
significantly impact the quality of the human environment, as the
environmental impacts are bounded by the previous EA for renewal of
SNM-2509.
Therefore, the NRC finds that there are no significant
environmental impacts from the proposed action, and that preparation of
an environmental impact statement is not warranted. Accordingly, the
NRC has determined that a FONSI is appropriate.
