s in risk associated with maintenance activities. In a series of public meetings, the NRC staff met with industry representatives to discuss the change in the rule in relation to proposed revisions to Revision 2 of NUMARC 93-01, "Industry Guideline for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants"1 (May 1993). Revision 2 of NUMARC 93-01 was prepared by the Nuclear Energy Institute (NEI) and is endorsed by Revision 2 of Regulatory Guide 1.160, "Monitoring the Effectiveness of Maintenance at Nuclear Power Plants."2 Based in part on these discussions with industry representatives, this Regulatory Guide 1.182 provides guidance on implementing the provisions of 10 CFR 50.65(a)(4) by endorsing a revised Section 11 to NUMARC 93-01. Regulatory Guide 1.182 will be used as a companion guide to Regulatory Guide 1.160 as guidance on methods acceptable to the NRC staff for assessing and managing the increase in risk that may result from maintenance activities and for implementing the optional reduction in scope of SSCs considered in the assessments. The information collections contained in this regulatory guide are covered by the requirements of 10 CFR Part 50, which were approved by the Office of Management and Budget, approval number 3150-0011. If a means used to impose an information collection does not display a currently valid OMB control number, the NRC may not conduct or sponsor, and a person is not required to respond to, the information collection. B. DISCUSSION The objective of the Maintenance Rule, 10 CFR 50.65, is to require monitoring of the overall continuing effectiveness of licensee maintenance programs to ensure that (1) safety-related and certain nonsafety-related structures, systems, and components (SSCs) are capable of performing their intended functions, (2) for nonsafety-related equipment, failures will not occur that prevent the fulfillment of safety-related functions, and (3) failures resulting in scrams and unnecessary actuations
