{"abstract":"The Department of Energy (DOE) is today publishing a final rule to amend regulations that prohibit the unauthorized dissemination of certain unclassified but sensitive information identified as Unclassified Controlled Nuclear Information (UCNI). DOE is amending these regulations to clarify the types of information that may be identified as UCNI; to prevent overly-broad application of UCNI controls; and to streamline the UCNI program by simplifying the process for identifying information as UCNI.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF ENERGY","name":"Energy Department","id":136,"url":"https://www.federalregister.gov/agencies/energy-department","json_url":"https://www.federalregister.gov/api/v1/agencies/136","parent_id":null,"slug":"energy-department"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2008/06/10/E8-12978.html","cfr_references":[{"chapter":null,"citation_url":null,"part":1017,"title":10}],"citation":"73 FR 32637","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective Date: This final rule is effective December 8, 2008.","disposition_notes":null,"docket_ids":[],"dockets":[],"document_number":"E8-12978","effective_on":"2008-12-08","end_page":32648,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2008/06/10/E8-12978.xml","html_url":"https://www.federalregister.gov/documents/2008/06/10/E8-12978/identification-and-protection-of-unclassified-controlled-nuclear-information","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E8-12978?publication_date=2008-06-10","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2008-06-10/E8-12978/mods.xml","not_received_for_publication":null,"page_length":12,"page_views":{"count":277,"last_updated":"2026-10-25 06:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2008-06-10/pdf/E8-12978.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2008-06-10","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2008/06/10/E8-12978.txt","regulation_id_number_info":{"1992-AA35":{"issue":"200804","html_url":"https://www.federalregister.gov/regulations/1992-AA35/identification-and-protection-of-unclassified-controlled-nuclear-information","title":"Identification and Protection of Unclassified Controlled Nuclear Information","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200804&RIN=1992-AA35&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["1992-AA35"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-11-14T06:56:44Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":32637,"subtype":null,"title":"Identification and Protection of Unclassified Controlled Nuclear Information","toc_doc":"Identification and Protection of Unclassified Controlled Nuclear Information","toc_subject":null,"topics":["Administrative practice and procedure","Government contracts","Nuclear energy","Penalties","Security measures"],"type":"Rule","volume":73}
