The paper deals with the optimization of parameters (mass parameters of stiff bodies) of the dynamic model of the reactor WWER 1000 support cylinder. Within the model of the whole reactor, support cylinder appears to be a significant subsystem for its modal properties having dominant influence on the behaviour of the reactor as a whole. Relative sensitivities of eigenfrequencies to the change of the discrete parameters of the model were determined. Obtained values were applied in the following spectral tuning process of the (selected) discrete parameters. Tuning itself is formulated as an optimization problem.
