Automated control and safety of nuclear power plants

Abstract

The conceptual problems of developing and modernizing an automated system for the control of a technological process for nuclear power plants, which are under construction, or are currently operating, are discussed. Attention is focused on the human factor in the control of a nuclear power plant. The prospects for solving problems such as the optimal – from the safety standpoint – separation of control functions between man and machine, choice of means of automation adequate for the importance of the functions being performed with respect to safety, determination of the concept of the operator's job, and the systems for supporting the operator's work, and development of a modern man–machine interface, are examined. The solution of these problems is studied on the basis of a homocentric model of an automated system for controlling a technological process. The model uses extensively subsystems for supporting the work performed by the operator. It is noted that a supervisor role for the operator is preferable, since it provides the best psychological work environment. 11 references.
