Clinch River Nuclear Site Advanced Nuclear Reactor Technology Park

Oak Ridge, Roane County, Tennessee

Notice of Intent to Prepare a Programmatic Environmental Impact Statement

On February 2, 2021, TVA published a Notice of Intent (NOI) to prepare a Programmatic Environmental Impact Statement (PEIS) to address the potential environmental effects associated with the construction, operation, and decommissioning of an advanced nuclear reactor technology park at TVA’s 935-acre Clinch River Nuclear (CRN) Site in Oak Ridge, Roane County, Tennessee. The park would contain one or more advanced nuclear reactors with a cumulative electrical output not to exceed 800 megawatts electric (MWe).

This project supports TVA’s 2019 Integrated Resource Plan by continuing to evaluate emerging nuclear technologies as part of technology innovation efforts aimed at developing future generation capacities. This project would evaluate and demonstrate the feasibility of deploying advanced nuclear reactors to support TVA’s mission of providing safe, clean, reliable, and low-cost energy to the Tennessee Valley. The consideration of a new nuclear facility at the CRN Site support’s TVA’s mission statement and is another way to assess how to serve the people of the Tennessee Valley.

The PEIS will address a range of alternatives for construction, operation, and decommissioning of an advanced nuclear reactor technology park at the CRN Site. Action alternatives include the construction of light water reactor (LWR) alternatives and/or non-LWR alternatives at the CRN Site. There are two areas within the CRN Site that are best suitable for development; these are designated as Area 1 and Area 2. Therefore, TVA plans to evaluate four discrete alternatives (A-D) for these proposed actions including the No-Action Alternative (A) and an advanced nuclear reactor technology park at Area 1 (B); at Area 2 (C); at Area 1 and Area 2 (D). Two additional alternatives E and F were considered but eliminated.

The NOI is provided in accordance with the Council on Environmental Quality’s (CEQ) regulations for implementing the National Environmental Policy Act (NEPA) at 40 CFR parts 1500-1508 and Section 106 of the National Historic Preservation Act (NHPA), and its implementing regulations (36 CFR Part 800). The PEIS will be prepared consistent with the 2020 CEQ regulations for implementing NEPA at 40 CFR parts 1500-1508 (85 FR 43304-43376, Jul. 16, 2020).

Public Involvement

TVA released the NOI on February 2, 2021 for the public scoping period until March 19, 2021. The public was invited to submit comments on the scope of this PEIS, alternatives being considered, and environmental issues.

TVA hosted an open house on March 1, 2021, from 6:00 – 8:00 ET.
