The documents posted on this site are XML renditions of published Federal

The OFR/GPO partnership is committed to presenting accurate and reliable
regulatory information on FederalRegister.gov with the objective of
establishing the XML-based Federal Register as an ACFR-sanctioned
publication in the future. While every effort has been made to ensure that
the material on FederalRegister.gov is accurately displayed, consistent with
the official SGML-based PDF version on govinfo.gov, those relying on it for
legal research should verify their results against an official edition of
the Federal Register. Until the ACFR grants it official status, the XML
rendition of the daily Federal Register on FederalRegister.gov does not
provide legal notice to the public or judicial notice to the courts.

II. Discussion
By letter dated May 7, 2026, Nebraska Public Power District (NPPD) submitted to the NRC an application for subsequent license renewal (SLR) of Cooper Renewed Facility Operating License No. DPR-46 for an additional 20 years of operation. This submission
( printed page 36161)
initiated the NRC's proposed action of determining whether to grant the SLR. Cooper is located in Brownville, Nebraska. The current Cooper license expires at midnight on January 18, 2034. The SLR application was submitted pursuant to part 54 of title 10 of the
Code of Federal Regulations
(10 CFR), “Requirements for Renewal of Operating Licenses for Nuclear Power Plants,” and seeks to extend the license for Cooper to midnight on January 18, 2054. A notice of receipt and availability of the application was published in the
Federal Register
on May 21, 2026 (91 FR 29989). A notice of acceptance for docketing of the application and of an opportunity to request a hearing was published in the
Federal Register
on June 10, 2026 (91 FR 35275) and is available on the Federal Rulemaking website (
https://www.regulations.gov) by searching for Docket ID NRC-2026-2344.
III. Request for Comment
This notice informs the public of the NRC's intention to conduct environmental scoping and prepare an supplemental EIS related to the SLR application for Cooper and provides the public an opportunity to participate in the environmental scoping process, as defined in 10 CFR 51.29, “Scoping-environmental impact statement and supplement to environmental impact statement,” and 10 CFR 51.116, “Notice of intent.”
The NRC intends to gather the information necessary to prepare the supplemental EIS as a plant-specific supplement to NUREG-1437, Revision 2, “Generic Environmental Impact Statement for License Renewal of Nuclear Plants” (ADAMS Package Accession No. ML24087A133). The supplemental EIS will evaluate the environmental impacts of SLR for Cooper, and a reasonable range of alternatives, including the no-action alternative. This notice is being published in accordance with NEPA and the NRC's regulations at 10 CFR part 51.
As part of its environmental review, the NRC will first conduct a scoping process for the supplemental EIS and, as soon as practicable thereafter, will prepare a draft supplemental EIS for public comment. Participation in this scoping process by members of the public and local, State, Tribal, and Federal government agencies is encouraged. The scoping process for the supplemental EIS will be used to accomplish the following:
a. Define the proposed action that is to be the subject of the supplemental EIS;
b. Determine the scope of the supplemental EIS and identify the significant issues to be analyzed in depth;
c. Identify and eliminate from detailed study those issues that are peripheral or are not significant or that have been covered by prior environmental review;
d. Identify any environmental assessments and other environmental impact statements that are being or will be prepared that are related to, but are not part of, the scope of the supplemental EIS under consideration;
e. Identify other environmental review and consultation requirements related to the proposed action;
f. Indicate the relationship between the timing of the preparation of the environmental analyses and the NRC's tentative planning and decision-making schedule;
g. Identify any cooperating agencies and, as appropriate, allocate assignments for preparation and schedules for completing the supplemental EIS to the NRC and any cooperating agencies; and
h. Describe how the supplemental EIS will be prepared, including any contractor assistance to be used.
The NRC invites the following entities to participate in scoping:
a. The applicant, NPPD;
b. Any Federal agency that has jurisdiction by law or special expertise with respect to any environmental impact involved or that is authorized to develop and enforce relevant environmental standards;
c. Affected State and local government agencies, including those authorized to develop and enforce relevant environmental standards;
d. Any affected Indian Tribe;
e. Any person who requests or has requested an opportunity to participate in the scoping process; and
f. Any person who has petitioned or intends to petition for leave to intervene under 10 CFR 2.309.
Participation in the scoping process for the Cooper SLR supplemental EIS does not entitle participants to become parties to the proceeding to which the supplemental EIS relates.
