Methods of quantitative validation fo r dynamic simulation models

Four examples, taken from nuclear-power-station experience are described, where model-distortion techniques have been applied successfully. These examples are: (i) Validation of a power-station model for the prediction of behaviour followirag a trip; (ii) validation of a nuclear-reactor model for the purposes of control-system design; (iii) validation of a pump run-down model; and (iv) validation of a model for a hydraulic accumulator.
