II. Discussion

The NRC intends to develop a GEIS for advanced nuclear reactors with a small generating output and correspondingly small environmental footprint in order to streamline the environmental review process for future small-scale advanced nuclear reactor environmental reviews. The purpose of an ANR GEIS is to determine which environmental impacts could result in essentially the same (generic) impact for different advanced nuclear reactor designs that fit within the parameters set in the GEIS, and which environmental impacts could result in different levels of impacts requiring a plant-specific analysis. Environmental reviews for small-scale advanced nuclear reactor license applications could incorporate the ANR GEIS by reference and provide site-specific information and analyses in a Supplemental Environmental Impact Statement (SEIS), thereby streamlining the environmental review process. In SECY-20-0020 (ADAMS Accession No. ML20052D175), the staff informed the Commission that it plans to use a technology-neutral plant parameter envelope (or PPE) approach to bound small-scale ANR projects. For the purposes of the ANR GEIS, the staff considers a “small-scale” ANR as having the potential to generate up to approximately 30 megawatts thermal per reactor with a correspondingly small environmental footprint. The actual bounding thermal power level of the ANR and the environmental footprint used in the ANR GEIS are topics to be determined during the scoping process.

Because small-scale advanced reactors are not specific to only one reactor design and could be sited anywhere in the United States that meets NRC siting requirements, the NRC decided to pursue a technology neutral approach using a PPE. The PPE will consist of a table of bounding values or parameters for different reactor designs located on a site. In addition, a table of values representing the site parameter envelope (e.g., size of site, quantity of water used, demographics) will be developed to describe the affected environment. The ANR GEIS will evaluate the impacts of a reactor that fits within the bounds of the PPE on a site that fits within the bounds of the site parameter envelope to determine the environmental impact.

An application that references the ANR GEIS will need to demonstrate that its project is bounded by the analysis in the ANR GEIS and that there is no significant new information affecting the evaluation. The application will also need to analyze the site-specific resources not resolved generically in the ANR GEIS. If the project is bounded by the ANR GEIS and there is no significant new information, the NRC will incorporate by reference the ANR GEIS and no further analysis would be needed for a resource that was resolved generically. If impacts to a resource have not been resolved generically by the ANR GEIS, the site-specific SEIS will evaluate the impacts to the resource.

The NRC will not authorize construction or operation of any advanced nuclear reactors through the Start Printed Page 24042ANR GEIS. Consultation required by Section 106 of the National Historic Preservation Act and Section 7 of the Endangered Species Act will be conducted and included in the SEIS for each application and will not be part of the ANR GEIS.

III. Request for Comments

This document informs the public of the NRC's intention to conduct scoping and prepare an ANR GEIS for small-scale advanced nuclear reactors. The NRC is seeking input from the public and stakeholders regarding the parameters that the NRC should use to bound the small-scale advanced reactors in the plant parameter envelope (including power level and size of the site) and the parameters that should be used to bound the affected environment in the site parameter envelope. In addition, the NRC is seeking input on resources or issues that can be resolved generically and ones that cannot.

This document is being published in accordance with National Environmental Policy Act and the NRC's regulations found at part 51 of title 10 of the Code of Federal Regulations (10 CFR). The NRC will first conduct scoping for the ANR GEIS and, as soon as practicable thereafter, will prepare a draft ANR GEIS for public comment. Participation in the scoping process by members of the public and local, State, Tribal, and Federal government agencies is encouraged. In accordance with 10 CFR 51.29 the scoping process will be used to accomplish the following:

a. Define the proposed action;

b. Determine the scope of the ANR GEIS 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 were covered by a prior environmental review;

d. Identify any Environmental Assessments and other Environmental Impact Statements (ElSs) that are being or will be prepared that are related to, but are not part of, the ANR GEIS being considered;

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 ANR GEIS and the Commission's tentative planning and decision-making schedule;

g. Identify any cooperating agencies and, as appropriate, allocate assignments for preparation and schedules for completing the ANR GEIS to the NRC and any cooperating agencies; and

h. Describe how the ANR GEIS will be prepared, including any contractor assistance to be used.

The NRC invites the following entities to participate in scoping:

a. 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;

b. Affected State and local government agencies, including those authorized to develop and enforce relevant environmental standards;

c. Any affected Indian Tribe; and

d. Any person who requests or has requested an opportunity to participate in the scoping process.

IV. Public Scoping Webinar

In accordance with 10 CFR 51.26(b), the scoping process for an EIS may include a public scoping meeting, which may help identify significant issues related to a proposed activity and to determine the scope of issues to be addressed in an EIS.

The NRC is announcing that it will hold the public meeting as a webinar. The webinar will be held online and will offer a telephone line for members of the public to submit comments. A court reporter will be recording all comments received during the webinar. To be considered, comments must be provided either at the transcribed public meeting or in writing, as discussed in the ADDRESSES section of this document.
