Implementation of Control Logic for Mitigating Systems in DCS

Abstract

The ADVANCED CANDU REACTOR® (ACR-1000®) uses a distributed control system (DCS) to perform control and monitoring tasks. This paper briefly describes the control system architecture and presents the conceptual implementation strategy for the control logic for three ACR-1000 systems (heat transport system pumps, second crash cooldown system and reserve water system) in the essential control sub-system (ECSS). The paper also goes on to define the basis for the implementation strategies for each system.
