T. Sakaue et al., INTEGRATED DIGITAL (I-AND-C) SYSTEMS FOR NEXT-GENERATION LIGHT-WATER REACTOR PLANTS, Nippon Genshiryoku Gakkaishi, 36(8), 1994, pp. 704-713
The development of integrated digital Instrumentation and Control (I &
C) systems for Advanced Pressurized Water Reactor (APWR) and Advanced
Boiling Water Reactor (ABWR) have been promoted to meet the requireme
nts for increased reliability, enhanced operability and maintainabilit
y. The systems integrate state-of-the-art technologies for man-machine
interface, digital plant control and protection, optical multiplexing
signal transmission and ergonomics. The systems have been systematica
lly built on the hierarchically distributed architecture. This paper d
escribes the design philosophy and the features of the integrated digi
tal I & C systems for APWR and ABWR, focusing on improved man machine
interface and newly developed digital systems for plant control and pr
otection.
