Meeting Summary:

On July 22, 2025, the U.S. Nuclear Regulatory Commission (NRC) staff held a comment gathering public meeting in Kemmerer, WY. The purpose of this meeting was to provide an opportunity for the staff to describe the environmental review of the construction permit (CP) application from TerraPower USO for the Kemmerer Unit 1 reactor and to solicit comments from the public on the draft environmental impact statement (EIS) from attendees. This meeting allowed the NRC staff to meet directly with individuals to receive comments from participants to ensure that the staff understand their views and concerns.

The meeting notice and agenda are available in ADAMS ML25202A108. The NRC staffs presentation slides are also in ADAMS ML25202A004. In addition, transcripts of the meetings are in ADAMS ML25217A010. A list of attendees is provided in the Enclosure to this summary.

NUREG-2268, "Environmental Impact Statement for the Construction Permit Application for Kemmerer Power Station Unit 1" can be found at ML25154A651.

During each meeting, following the NRC staff introductions and welcoming remarks, staff from the NRCs Offices of Nuclear Materials Safety and Safeguards and Nuclear Reactor Regulation provided a presentation that gave an overview of the NRCs mission, described the Kemmerer Unit 1 facility that TerraPower USO is planning to construct in Kemmerer, WY and described the NRCs safety and environmental review process. The NRC staffs presentation provided a summary of the draft EIS and described the process for interested persons to submit comments during the comment period, which ended on August 4, 2025.

After the NRC staff presentation, attendees provided a total of one verbal comment during the afternoon meeting and four comments during the evening meeting. The comments were generally supportive of the NRCs review. Comments were focused on fuel storage, safety assurances, and past mining activities that may affect the project. Process questions were also asked with regard to timing and next steps for the CP and subsequent Operating License.

The verbal comments provided during the meeting and any written comments the NRC staff received during the scoping period will be considered in the NRC staffs development of its final EIS for the TerraPower Kemmerer Unit 1 application.
