SCREEN-BASED PROCESS-CONTROL IN NUCLEAR-PLANTS

Requirements, development and conceptual design of a screen-based cont rol room for nuclear power plants are outlined. The control room consi sts of three or four equally equipped operator workstations comprising screens for process information and manual process control. A plant o verview will assist the co-ordination among the operators. A safety cl assified backup system (safety control area) is provided to cover post ulated failures of the control means. Some aspects of ergonomical vali dation and of future development trends are discussed.
