{"abstract":"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.","action":"Notice; issuance.","agencies":[{"raw_name":"NUCLEAR REGULATORY COMMISSION","name":"Nuclear Regulatory Commission","id":383,"url":"https://www.federalregister.gov/agencies/nuclear-regulatory-commission","json_url":"https://www.federalregister.gov/api/v1/agencies/383","parent_id":null,"slug":"nuclear-regulatory-commission"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/04/06/2026-06571.html","cfr_references":[],"citation":"91 FR 17312","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The final SEIS is available as of April 1, 2026.","disposition_notes":null,"docket_ids":["Docket No. 50-615","NRC-2024-0146"],"dockets":[],"document_number":"2026-06571","effective_on":null,"end_page":17313,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/04/06/2026-06571.xml","html_url":"https://www.federalregister.gov/documents/2026/04/06/2026-06571/tennessee-valley-authority-clinch-river-nuclear-site-unit-1-final-supplemental-environmental-impact","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-06571?publication_date=2026-04-06","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-04-06/2026-06571/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":39,"last_updated":"2026-04-06 00:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-04-06/pdf/2026-06571.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-06571.pdf?1775220308","publication_date":"2026-04-06","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/04/06/2026-06571.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2026-04-04T08:47:16Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":17312,"subtype":null,"title":"Tennessee Valley Authority; Clinch River Nuclear Site, Unit 1; Final Supplemental Environmental Impact Statement","toc_doc":"Tennessee Valley Authority, Clinch River Nuclear Site, Unit 1","toc_subject":"Environmental Impact Statements; Availability, etc.","topics":[],"type":"Notice","volume":91}
