Nuclear Reactor Control Room Simulators: Human Factors Research and Development

Abstract

Simulator studies are powerful means for understanding, designing and managing the complexity of nuclear reactor control if, along with their scenarios, they are correctly designed for that purpose. This contribution to an international state of the art of the use of nuclear reactor control room simulators in human factors research and development summarises the trends and novelties in the theories and methodologies (the reduction of the ambitions of cognitive simulation and the renewal of process-tracing methods, the eclectic search for theoretical and methodological complementarity, the conquests of situation awareness and their limitations, the study of cooperation), in the use of the results (with stress on probabilistic human reliability analysis and design of procedures) and in the construction of simulated situations (with stress on part task simulations and on relations between testing practical and empirical hypotheses and testing theoretical ones).
