Lars-Erik Häll, Altti Lucander, "Experiences of Computer Systems in Instrumentation and Control of a BWR Power Plant," Specialists' Meeting on Systems and Methods for Aiding Nuclear Power Plant Operators During Normal and Abnormal Conditions, Hungary, Baltonaliga, 4-6 October, 1983


The computer system facilities provided in the central control room of the units are realized utilizing three unit specific computer systems and one computer system common to both units. The unit specific systems are: the general process computer system, the measurement and disturbance computer system and the turbnine vibration monitoring computer system. Obly the process computer system was included in the original plant delivery. The dedicated systems have been acquired based on experiences during the start-up of the units. The structure of the computer systems including the process and man-machine interfaces is presented in Fig. 2 [right].
