Abstrakt CZ: The paper describes a spatial model of VVER1000 type reactor with 137 DOF in configuration space defined by relative diplacements. The model is createc grom rigid bodies and one-dimensional continuums linked discrete linear elastic couplings. Reactor is excited by pressure pulsations generated by main circulation pumps in coalant loops. Slightly different pumps revolutions in particular loop are souces of beating. The method is applied to the concrete reactor. The software developed in MATLAB and enables a graphic image of amplitude characteristics and orbits of points at pressure vessel axis.
