PLANTS A. INTRODUCTION This guide describes a method that the staff of the U.S. Nuclear Regulatory Commission (NRC) considers acceptable for condition monitoring for electric cables for nuclear power plants, for those licensees choosing to use monitoring to meet the requirements of Title 10, Part 50, “Domestic Licensing of Production and Utilization Facilities” of the Code of Federal Regulations (10 CFR Part 50) (Ref. 1), Section 50.65, “Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants.” Paragraph (a)(1) of 10 CFR 50.65, states that “Each holder of an operating license for a nuclear power plant...shall monitor the performance or condition of structures, systems, or components...in a manner sufficient to provide reasonable assurance that these structures, systems, and components...are capable of fulfilling their intended functions.” Licensees may, as an alternative to compliance with paragraph (a)(1) of the Maintenance Rule, comply with the requirements of paragraph (a)(2). That paragraph allows a licensee to avoid monitoring if it can demonstrate that the condition or performance of a SCC within the scope of the rule is being effectively controlled through preventative maintenance. Regulatory Guide 1.160, “Monitoring the Effectiveness of Maintenance at Nuclear Power Plants,” (Ref. 2) provides general guidelines for complying with 50.65(a)(1). This Regulatory Guide provides specific guidance for condition monitoring of cables to provide reasonable assurance that the cables are capable of performing their intended function(s) during their installed life. In particular, this regulatory guide describes a programmatic approach to condition monitoring of electric cable systems and their operating environments and acceptable condition monitoring techniques. The programmatic approach and condition monitoring may be used to demonstrate compliance with either paragraphs (a)(1) or (a)(2) of the Maintenance Rule. DG-1240,
