Supervisory and control systems for nuclear power plants are important not only as means for executing control logic
but also as means for providing a human-machine interface for operators. Hitachi, Ltd. is accordingly doing continuous
R&D work on high-quality supervisory and control systems, and through such work has developed such products as
integrated digital systems for centralized monitoring and control of Advanced Boiling Water Reactors (ABWRs),
and simulators for use in training personnel in reactor operation. At the same time, remarkable progress has been made
in recent years in developing such human-machine interface technologies as graphical user interfaces and multi-window
systems, fueled by the ongoing technology revolution and the increasingly widespread use of personal computers.
And incorporating these technologies and increasing their reliability are becoming important issues. To address these issues,
Hitachi has developed (1) a client-server architecture to realize efficient plant monitoring and operation functions,
(2) a high-performance controller as a core means of preserving system reliability, and (3) a system featuring added
flexibility and expandability by connecting (1) and (2) via a network. The system was installed to provide digital
supervision and control of liquid and solid radioactive waste treatment equipment at Tohoku Electric Power Co., Inc.'s
Onagawa Nuclear Power Plant No. 3.
