Distributed Control System for CANDU 9 Nuclear Power Plant

Abstract

Canadian designed CAW pressurized heavy water nuclear reactors have been world leaders in electrical power generation. The CAW 9 project is AECL 's next reactor design. The WDU 9 plant monitoring, annunciation, and control functions are implemented in two evolutionary systems; the distributed control system (DCS) and the plant display system (PDS). The DCS implements most of the plant control functions in a single hardware platform. The DCS communicates with the PDS to provide the main operator interface and annunciation capabilities of the previous control computer designs along with human interface enhancements required in a modern control system.
