RE: NRC's outreach to the Shoshone Bannock Tribes on Oklo license application Attachments:
slides ML20147A677.pdf Good afternoon Mr. Sanford, Im just sending a quick response your question asked during the NRCs Advanced Nuclear Reactor Generic Environmental Impact Statement (ANR GEIS) scoping public meeting. Sandra Talley in the NRCs tribal liaison group has been in contact with Ms. Talia Martin of the Shoshone Bannock Tribes to discuss the Oklo license application. Ms. Talley can also arrange to provide you and Ms. Martin further information on the Oklo application.
Thank you again for participating in the public meeting today. Please contact us if we can provide further information to you on the Advanced Nuclear Reactor Generic Environmental Impact Statement. We would also be interested in receiving your comments concerning the scope of the ANR GEIS too.
Im attaching the meeting presentation slides for your convenience.

Scoping Meeting Small-Scale Advanced Reactor Generic Environmental Impact Statement (GEIS)
Jack Cushing, Sr. Project Manager Laura Willingham, Project Manager U.S. Nuclear Regulatory Commission May 28, 2020 Bridge line: (888) 622-9844; Pass Code: 5484985 Webinar Info: https://usnrc.webex.com; Meeting No: 905642855 Technical Difficulties? Please email Daniel.Barnhurst@nrc.gov
2 Purpose of the Meeting
- Overview of the NRCs Mission
- What is a GEIS
- Describe the NRCs environmental review process and scoping
- Approach for developing the GEIS
- Describe how you can provide comments during the scoping period
- Listen to and gather your comments
3 Who We Are and What We Do U.S. Nuclear Regulatory Commission
- Independent Federal Agency
- Over 45 years of experience regulating operating reactors and other civilian use of nuclear materials
- Mission: To protect public health and safety, promote common defense and security, and protect the environment
4 What is a GEIS
- A type of environmental impact statement that considers the environmental impacts of environmental issues to reach generic or common conclusions.
- An application specific review is required for any environmental issues that are not generic and would be analyzed in a supplemental environmental impact statement.
- A GEIS streamlines the environmental review because the site specific review only needs to focus on unbounded category 1 issues and category 2 issues.
5 Environmental Review Process Decision to Develop GEIS Notice of Intent Published Information Gathering:
Scoping and other sources Draft GEIS Issued Final GEIS Issued Comments On Draft GEIS Scoping Process
6 Scoping Process
- Scoping process helps determine the significant issues to be analyzed in an environmental impact statement
- Comments that are relevant are considered in developing the environmental impact statement
- A Scoping Summary Report will be issued following the close of the scoping period
7 Scoping Process for the GEIS
- Identify the parameters needed to evaluate the environmental impacts of constructing and operating a small-scale advanced reactor
- Help us identify issues that can be resolved generically in the GEIS and issues that will need to be addressed in a site-specific supplemental environmental impact statement
- GEIS scoping period ends on June 30, 2020
8 GEIS Background
- Staff issued an information paper (SECY 20-0020) informing the Commission that it planned to develop an advanced reactor GEIS for small-scale reactor of approximately 30 megawatts thermal.
- Exact power level to be determined in scoping process.
9 GEIS Approach
- Generally follow approach of license renewal GEIS. Address construction and operational impacts
- Determine which environmental issues will be categorized as generic (category 1) or site-specific (category 2)
- Supplemental environmental impact statement issued for each future application.
10 GEIS Approach (Cont.)
How to generically evaluate the impacts from any type of advanced reactor located anywhere in the US?
- Establish limits on the size of the reactor and the site so most environmental impacts would be category 1.
- Use a technology inclusive plant parameter envelope to bound all types of small-scale reactors.
- Use a site parameter envelope to bound the site.
11 GEIS General Assumptions
- Assumes the site meets NRC regulations in 10 CFR 100 Reactor Siting Criteria
- Assumes the reactor meets NRC dose limits in 10 CFR 20 Standards for Protection Against Radiation
- Project can receive required permits from other agencies
- Standard mitigation practices followed (best management practices)
