INTRODUCTIONThis guide describes a method that the staff of the U.S. Nuclear Regulatory Commission (NRC) considers acceptable for complying with the Commission’s regulations for the qualification of safetyrelated cables and field splices for nuclear power plants. The regulations established by the NRC in Title 10, Part 50, “Domestic Licensing of Production and Utilization Facilities,” of the Code of Federal Regulations (10 CFR Part 50) (Ref. 1) require that structures, systems, and components that are important to safety in a nuclear power plant must be designed to accommodate the effects of environmental conditions (i.e., remain functional under postulated design-basis events (DBEs)). Toward that end, General Design Criterion (GDC) 1, “Quality Standards and Records,” GDC 2, “Design Bases for Protection Against Natural Phenomena,” GDC 4, “Environmental and Dynamic Effects Design Bases,” and GDC 23, “Protection System Failure Modes,” of Appendix A, “General Design Criteria for Nuclear Power Plants,” to 10 CFR Part 50 contain the general requirements. Augmenting those general requirements, the specific requirements pertaining to the qualification of certain electrical equipment important to safety are contained in 10 CFR 50.49, “Environmental Qualification of Electric Equipment Important to Safety for Nuclear Power Plants.” In addition, Criterion III, “Design Control,” of Appendix B, “Quality Assurance Criteria for Nuclear Power Plants,” to 10 CFR Part 50 requires that, when a test program is used to verify the adequacy of a specific design feature, the test program must include suitable qualification testing of a prototype unit under the most severe DBE. This regulatory guide contains information collection requirements covered by 10 CFR Part 50 that the Office of Management and Budget (OMB) approved under OMB control number 3150-0011.The NRC issues regulatory guides to describe and make available to the public methods that the NRC staff considers acceptable for use in implementing specific parts of the agency’s regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in reviewing applications for permits and licenses. Regulatory guides are not substitutes for regulations, and compliance with them is not required. Methods and solutions that differ from those set forth in regulatory guides will be deemed acceptable if they provide a basis for the findings required for the issuance or continuance of a permit or license by the Commission. This guide was issued after consideration of comments received from the public. Regulatory guides are issued in 10 broad divisions: 1, Power Reactors; 2, Research and Test Reactors; 3, Fuels and Materials Facilities; 4, Environmental and Siting; 5, Materials and Plant Protection; 6, Products; 7, Transportation; 8, Occupational Health; 9, Antitrust and Financial Review; and 10, General. Electronic copies of this guide and other recently issued guides are available through the NRC’s public Web site under the Regulatory Guides document collection of the NRC’s Electronic Reading Room at http://www.nrc.gov/reading-rm/doccollections/reg-guides/ and through the NRC’s Agencywide Documents Access and Management System (ADAMS) at http://www.nrc.gov/reading-rm/adams.html, under Accession No. ML082530205.The NRC may neither conduct nor sponsor, and a person is not required to respond to, an information collection request or requirement unless the requesting document displays a currently valid OMB control number.B. DISCUSSIONThe Institute of Electrical and Electronics Engineers, Inc. (IEEE) Standard 383-2003, “IEEE Standard for Qualifying Class 1E Electric Cables and Field Splices for Nuclear Power Generating Stations,” was published June 10, 2004 (Ref. 2). The standard was developed by the Working group on Cables (Subcommittee (SC 2.4)) of the Nuclear Power Engineering Committee of the IEEE and was approved by the IEEE Standards Association on December 12, 2003 (Reaffirmed in 2008). It provides general requirements, direction, and methods for qualifying safety-related cables, field splices, factory splices, and factory rework for service in nuclear power plants. Categories of cables covered include those used for power, control, and instrumentation services, including signal and communication cables. Most importantly, IEEE Standard 383-2003 requires that the safety-related cables and field splices must meet or exceed specified performance requirements throughout their installed life and be subjected to a quality assurance program that includes design, qualification, and production quality control.
