Probalistic reactor dynamics-3; A framework for time-dependent interaction between operator and reactor during a transient involving human error
- Univ. Libre de Bruxelles, Service de Metrologie Nucleaire, 50 avenue F.D. Roosevelt, 1050 Brussels (Belgium)
During an accident, components fail or evolve within operating states because of operator actions. Physical variables such as pressure and temperature vary, and alarms appear and disappear. Operators diagnose the situation and effect countermeasures to recover the accidental sequence in due time. In this paper, a mathematical modeling of the complex interaction process that takes place between the operating crew and the reactor during an accident is proposed. This modeling derives from a generalization of the theory of continuous event trees developed for hardware systems to a mixture of human and hardware systems. Such a generalization requires extension of the evolution equations built under the Markovian assumption to semi-Markovian processes because dead times as well as nonexponential distributions must be modeled.
