User-centred design of a computer-based control and surveillance system for nuclear power plant

A design and development programme for a future monitoring and control system applied to a small, high-integrity nuclear reactor is postulated. An overview is given of a user-centred approach to the design, from initial conceptual studies to full-scope simulation. The approach allows due consideration to be given to the use of human factors techniques, and use of computer aided design tools in the full design process. Many of the problems and difficulties frequently encountered can be addressed during a user-centered approach, leading to greater assurance that the design will be safer to operate, and well received by the end users. Such an approach would be applicable to any complex plant employing computer-based systems
