not been updated since its original issue. This revision updates the RG to endorse the current version of IEEE Std. 382-2006, with certain exceptions and modifications. Background IEEE Std. 382-2006, was published on March 15, 2007. It was developed by the Subcommittee on Qualification of Actuators (SC 2.3) of the IEEE Nuclear Power Engineering Committee and approved by the IEEE Standards Association (IEEE-SA) Standards Board on December 6, 2006. This standard establishes criteria for the qualification of safety-related actuators and actuator components, in nuclear power generating stations. The primary objective is to demonstrate with reasonable assurance that safety- related actuators for which a qualified life or condition has been established can perform their safety function(s) without common-cause failures before, during, and after applicable DBE. Safety-related actuators and their interfaces must meet or exceed the equipment specification requirements. The IEEE standard specifies procedures for testing under conditions that simulate (1) the postulated DBE conditions including specified high-energy line break, loss of coolant accident, main steam line break, and safe shutdown seismic earthquake events, and (2) those occurring during normal operating conditions. The standard specifies procedures for accomplishing aging of components to simulate the effects of long-term operation under normal and abnormal operating conditions. These effects include exposure to thermodynamic environment (temperature, pressure, relative humidity), fluid jet or spray environment, seismic and non-seismic vibration environment, radiation environment, anticipated variations in input power source (electrical and mechanical), and electrical and mechanical characteristics. The standard provides guidance for how to incorporate manufacturers’ recommended maintenance intervals into the qualification process.
