The increase of the alternate current frequency results in increased rotational speed of the electricalmotors and connected pumps. The consequence for the reactor coolant pumps is increased flow inprimary coolant system. Increase of the current frequency can be initiated by the subsynchronousresonance phenomenon (SSR). This paper analyses the implications of the SSR and consequential increase of the frequency on thenuclear power plant safety. The Simulink MATLAB® model of the steam turbine and governor system andRELAP5 computer code of the pressurized water reactor are used in the analysis. The SSR results in fast increase of reactor coolant pumps speed and flow in the primary coolant system. The turbine trip value is reached in short time following SSR. The increase of flow of reactor coolantpumps results in increase of heat removal from reactor core. This results in positive reactivity insertionwith reactor power increase of 0.5% before reactor trip is initiated by the turbine trip. The main parametersof the plant did not exceed the values of reactor trip set points. The pressure drop over reactorcore is small discarding the possibility of core barrel lift
