Based on a simple process model of the primary circuit in physical coordinates, model parameter estimation has been performed on a unit of the Paks Nuclear Power Plant using measured transient data. The dynamic model is hybrid and nonlinear in its parameters and variables, therefore an esti mation strategy based on the decomposition of the system has been applied. The estimated parameters fit well to their expected physical range, and the overall system response has also been reproduced in a satisfactory manner.
