The work estimates the impact of seismic activity on the electromechanical systems parameters. We have constructed a seismic impulse model in the MATLAB environment from among the actual seismograms used for the construction and investigated its influence on the operation of the reactor coolant pump set. The authors have also researched the impact of the equivalent impulses with the different carrier vibration frequency. We have constructed the chronograms of the unit shaft rotation and determined the output parameters of the system. The research results show that the seismic activity with the specified carrier frequency can have a destructive effect on the electromechanical system and result in the fatigue failure of the shaft in particular.
