lear Power Generating Stations,” (Ref. 8) and the American Society of Mechanical Engineers (ASME) Standard QME-1-2007, “Qualification of Active Mechanical Equipment Used in Nuclear Power Plant,” (Ref. 9) with specific conditions. ASME Standard QME-1-2007 incorporates lessons learned from valve operating experience and research programs for the qualification of power-operated valves used in nuclear power plants. For example, ASME QME-1-2007 includes more stringent provisions for the functional qualification of power-operated valves than specified in IEEE Std. 382-2006, including acceptable qualification methods, actuator grouping, actuator output capability testing, and extrapolation of actuator qualification. ASME QME-1-2007 specifies the seismic qualification of valve assemblies in accordance with IEEE Std. 344- 2004 as addressed in RG 1.100 or as described in the ASME standard. ASME QME-1-2007 specifies, in part, that valve actuators should be environmentally qualified in accordance with IEEE Std. 323-1983, “IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations,” (Ref. 10) and IEEE Std. 382-1985, “Standard for Qualification of Actuators for Power-Operated Valve Assemblies with Safety-Related Functions for Nuclear Power Plants” (Ref. 11). The NRC staff however, does not endorse the use of IEEE Std. 323-1983 or IEEE Std. 382- 1985, and only accepts the use of IEEE Std. 382-2006 for the environmental qualification of safety related actuators in nuclear power plants subject to the provisions of this RG. In this RG, environmental qualification includes such activities as aging (e.g., thermal, cycling, radiation, and vibration), pressurization cycle testing, radiation exposure testing, and ambient condition testing (e.g., temperature, pressure, moisture, and spray environment). The users of IEEE Std. 382-2006 will need to address the other aspects of the qualification process (such as seismic and functional qualification)
