{"abstract":"The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 5 to Regulatory Guide (RG) 1.97, \"Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants.\" This guide describes an approach that is acceptable to the staff of the NRC to meet regulatory requirements for instrumentation to monitor accidents in nuclear power plants. It endorses, with exceptions and clarifications, the Institute of Electrical and Electronic Engineers (IEEE) Standard (Std.) 497-2016, \"IEEE Standard Criteria for Accident Monitoring Instrumentation for Nuclear Power Generating Stations.\"","action":"Regulatory guide; 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/2019/05/01/2019-08819.html","cfr_references":[],"citation":"84 FR 18591","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Revision 5 to RG 1.97 is available on May 1, 2019.","disposition_notes":null,"docket_ids":["NRC-2017-0237"],"dockets":[{"supporting_documents":[{"title":"Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants (RG 1.197, Rev. 5)","document_id":"NRC-2017-0237-0012"},{"title":"Draft Regulatory Guide DG-1335 - Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants","document_id":"NRC-2017-0237-0002"}],"agency_name":"NRC","documents":[{"comment_count":null,"comment_start_date":null,"updated_at":"2025-05-21T01:11:12.562-04:00","comment_url":"https://www.regulations.gov/commenton/NRC-2017-0237-0011","allow_late_comments":false,"id":"NRC-2017-0237-0011","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"NRC-2017-0237","title":"Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants"}],"document_number":"2019-08819","effective_on":null,"end_page":18591,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2019/05/01/2019-08819.xml","html_url":"https://www.federalregister.gov/documents/2019/05/01/2019-08819/criteria-for-accident-monitoring-instrumentation-for-nuclear-power-plants","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2019-08819?publication_date=2019-05-01","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2019-05-01/2019-08819/mods.xml","not_received_for_publication":null,"page_length":1,"page_views":{"count":522,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2019-05-01/pdf/2019-08819.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2019-08819.pdf?1556628323","publication_date":"2019-05-01","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2019/05/01/2019-08819.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants (RG 1.197, Rev. 5)","document_id":"NRC-2017-0237-0012"},{"title":"Draft Regulatory Guide DG-1335 - Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants","document_id":"NRC-2017-0237-0002"}],"comments_count":0,"agency_id":"NRC","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=NRC-2017-0237","supporting_documents_count":2,"docket_id":"NRC-2017-0237","document_id":"NRC-2017-0237-0011","regulation_id_number":null,"title":"Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants","checked_regulationsdotgov_at":"2025-05-22T06:55:06Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":18591,"subtype":null,"title":"Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants","toc_doc":"Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants","toc_subject":"Guidance:","topics":[],"type":"Notice","volume":84}
