Abstract
The present invention relates to a nuclear power plant defense-in-depth safety apparatus having diversity, comprising: an analog type first control unit for generating an operation signal for a safety system; a digital type second control unit for generating an operation signal for the safety system; and a device interface module for receiving the operation signal of the first control unit and the operation signal of the second control unit and applying the operation signal of the first control unit to the safety system as a top priority.
Claims8
A defense-in-depth safety apparatus with diversity in a nuclear power plant, the apparatus comprising:
- an analog-type first controller configured to generate an operation signal for a safety system;
- a digital-type second controller configured to generate an operation signal for the safety system;
- and
- a component interface module (CIM) configured to receive the operation signal from the first controller and the operation signal from the second controller, and apply first the operation signal from the first controller to the safety system as a top priority.
