Enertech, a business unit of Curtiss Wright Flow Control Company and leader in the supply of electrohydraulic, gas spring actuators used for safe plant shut-down applications, has developed an extended mission model to support nuclear plant cool down during station blackout conditions.
Enertech’s advanced technology permits bi-directional, mid-position cycling of throttling valves and dampers from stored energy for a 72 hour period or longer without dependency on off-site power, emergency diesel generator power or air supply. The space required to facilitate Enertech’s stored energy module is a fraction of that required by traditional air supply tanks and control panels used in early generation nuclear plants. Enertech’s extended mission actuator is qualified for harsh environment to IEEE 382, 344 and 323 for survival in high energy line break as well as severe seismic and other design basis conditions including its position feedback instrumentation for modulating control service. Enertech has received orders for this safe plant shut down technology and offers it to Utility and Station Owners for plant upgrade and to valve and damper OEMs.
