Electric actuators for nuclear power stations are designed to active duty located outside containment with reactors of type VVER. They can be used for the selected devices of the security class II and III (2 and 3).
The main characteristic features of the electric actuators for nuclear plants:
• 40 years lifetime
• seismicity resistance up to 8g (within a frequency interval 4-35 Hz)
• functional resistance to an emergency environment HELB (3-6 hours), in the fume environment with a temperature 110 °C and pressure ranged between 0,2
• seismic group 1a
