This coupled multibody system is decomposed into subsystems modeled in the special configuration spaces of supporting subsystems. In comparison with original reactor models the spatial localization of the nuclear reactor fuel assembly and protection tubes, continuously mass distribution of beam type components and more accurate modelling of the linear stepper drives for actuation of control cassettes are respected. This new reactor mathematical model is aimed to the vibration analysis of internal components of the reactor excited by preasure pulsation generated by main circulation pumps. A model verification is performed by means of eigenfrequencies and eigenmodes.
