The U.S. Nuclear Regulatory Commission (NRC), in cooperation with the U.S. Army Corps of Engineers, is issuing a final supplemental environmental impact statement (SEIS), "Environmental Impact Statement for a Construction Permit Application at the Clinch River Nuclear Site: Final Report." The NRC is issuing this final SEIS as part of its review of the application submitted by Tennessee Valley Authority (TVA) for a construction permit (CP) for one GE Vernova Hitachi BWRX-300 small modular reactor (SMR) at a site in Roane County, Tennessee, designated as Clinch River Nuclear Site, Unit 1 (CRN-1). TVA plans to construct and operate CRN-1 to demonstrate the feasibility of constructing and operating the BWRX-300 SMR. The final SEIS evaluates the environmental impacts of the proposed action of issuing a CP that would allow the construction of CRN-1, as well as the environmental impacts of alternatives to the proposed action.
