Operator model-based design and evaluation of advanced systems: computational models

A multilevel operator modeling effort is recommended to provide broad support for integrated design of advanced control and protection systems for new nuclear power plants. A computational model called INTEROPS (integrated reactor operator system) is described which accounts for the cognitive activities of the operator by combining the advantages of network simulation and knowledge-based simulation. The INTEROPS model is a time-based simulation model which can be coupled with and control a thermal-hydraulics model of nuclear power plant. The INTEROPS model can provide fine-grained evaluation of allocation of functions during the iterative design phase of advanced systems.<
