The invention relates to a device and control method of electric control valve of a nuclear power plant, the control device for the electric valve movement control system for nuclear power plant includes an instruction processing module, instruction information for access to external, including electric valve status signal allows manual instruction, instruction, condition of automatic protection instructions, and the controlled electric valve feedback. And sent to the logic operation module; logic operation module, used by priority ascending order from the manual instructions, instructions, automatic protection directive for the current instruction, according to the current instruction and the condition control instructions to control the electric valve action, and according to the control instruction and electric valve the state signal generates a logic output signal; a display module for displaying the logic output signal. The invention improves the automatic operation level of the electric valve of the nuclear power station, and can also reduce the working load of the manipulator.
