Realisation of the integrated control room concept ISACS

The concept of an Integrated Surveillance And Control System (ISACS) has been developed into a first prototype, ISACS-1. ISACS-1 covers the whole interface between the process and the operator, and this interface is fully computerized. A large number of computerized operator support systems (COSSs) are included in ISACS, assisting in functions like disturbance detection, diagnosis and prognosis, identification of relevant actions, and implementation of procedures. An information coordinator in ISACS (the Intelligent Coordinator (IC)) observes the information received from the process and the COSSs, generates new high-level information, and structures and gives priority to information to be presented to the operator. ISACS-1 is subject to extensive evaluation, including large-scale operator experiments. The goal is to demonstrate how computer technology can efficiently be used to improve the operational safety and efficiency of nuclear power plants.<>
