The valves will be used for applications in the plants’ nuclear islands and in their passive residual heat removal system.
In the nuclear containment area, Emerson’s Fisher air-operated control valves will serve several functions related to operational safety.
As part of the safety related system, the valves are engineered to comply with government requirements, including ASME Section III standards for components of nuclear facilities, and undergo rigorous qualification testing at the new Emerson Innovation Center in Marshalltown, Iowa.
The valves’ actuators are sized in accordance with Electric Power Research Institute guidelines to ensure adequate operating margins that meet industry standards.
In the passive residual heat removal system, Emerson’s Fisher control valves will help achieve proper plant cooling during shutdown.
