Clinch River Nuclear Site Advanced Nuclear Reactor Technology Park

Oak Ridge, Roane County, Tennessee

Final Programmatic Environmental Impact Statement and Record of Decision

On September 29, 2022, TVA issued a Record of Decision (ROD) for site preparation, construction, operation, and decommissioning of various facilities at an advanced nuclear reactor technology park containing one or more advanced nuclear reactors with a cumulative output not to exceed 800 megawatts electric at TVA’s Clinch River Nuclear (CRN) Site in Oak Ridge, Roane County, Tennessee. TVA prepared the CRN Site Final Programmatic Environmental Impact Statement (PEIS), assessing the environmental impacts associated with the proposed action.

TVA has decided to implement the Preferred Alternative identified in the PEIS, Alternative D – Nuclear Technology Park at Area 1 and Area 2 with Small Modular Reactors (SMRs) and/or Advanced Non-Light Water Reactors (Non-LWRs). This decision provides the necessary flexibility in achieving the purpose and need of the project to support TVA’s goal of demonstrating the feasibility of deploying advanced nuclear reactor technologies at the CRN Site capable of incrementally supplying clean, secure, and reliable power that is less vulnerable to disruption.

The PEIS 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, July 16, 2020).

Previous Public Involvement

Public scoping was initiated with the publication of the Notice of Intent (NOI) to prepare a Draft PEIS in the Federal Register on February 5, 2021. Additionally, TVA posted a public notice about the scoping period and information regarding the Draft PEIS on A public scoping period was held from February 2 to March 19, 2021, and a virtual open house on March 1, 2021.

After consideration of comments received during the scoping period, TVA developed a Scoping Report that summarized public and agency comments that were received and identified the schedule for completing the EIS process. The scoping report was released in June 2021. 

On February 18, 2022, TVA released the Draft PEIS for a 45-day public comment period and a virtual open house on March 7, 2022. TVA received 18 formal comment submissions from members of the public, local government, and state and federal agencies. TVA’s responses to these comments are included in Appendix D of the CRN Final PEIS.
