This paper is about Curtiss Wright’s electro-hydraulic actuator environmental and seismic qualification for Main Steam Isolation Valve (MSIV) and Main Feedwater Isolation Valve (MFIV) applications. The qualification was performed in compliance with IEEE-382 and RCC-E requirements qualifying the actuator for US, Chinese and European power plant designs. The qualification entailed several challenges and application of analytical and test methodologies. The weight of the actuator/yoke assembly made seismic qualification one of the most challenging steps in the program. The seismic qualification was performed jointly with the Areva US Technical Center in Lynchburg, VA. The qualification program was designed to envelope the requirements power plant designs in US, China and Europe.
