ity of power-operated valves at NPPs. In RIS 2000-03, the NRC staff indicated that it would continue to monitor licensee activities to ensure that power-operated valves are capable of performing their safety-related functions under design-basis conditions. In an attachment to RIS 2000-03, the NRC staff provides a list of attributes to support the development of a successful power-operated valve program at NPPs. Through an extensive effort spanning many years, the ASME QME Standards Committee revised Section QV in ASME QME-1 to incorporate the lessons learned from the MOV operating experience and research programs for the functional qualification of all power-operated valves. The initial ASME QME Standards Committee efforts resulted in the publication of ASME QME-1-2007 with additional improvements provided in ASME QME-1-2012 (Ref. 31) and ASME QME-1-2017. Section C of this RG presents the staff’s regulatory positions on ASME QME-1-2017. Harmonization with International Standards The International Atomic Energy Agency (IAEA) has established a series of safety guides and standards constituting a high level of safety for protecting people and the environment. IAEA safety guides present international good practices and increasingly reflects best practices to help users striving to achieve high levels of safety. Pertinent to this regulatory guide, Sections 4 and 6 of IAEA Safety Guide NS-G-1.6, “Seismic Design and Qualification for Nuclear Power Plants,” issued October 2003 (Ref. 32), includes guidance for establishing various recommended approaches to qualify structures and equipment so that they meet the safety requirements established in IAEA Specific Safety Requirement 2/1, “Safety of Nuclear Power Plants: Design,” issued March 2016 (Ref. 33). This RG incorporates similar design and performance guidelines and is consistent with the safety principles provided in these publications.
