Using a General Purpose Computational and Experimental Method to Qualification Electrical Devices to Seismic Impact

This paper considers the methodology of evaluation of the stability of large-sized electrical equipment to the seismic impacts. Conclusions are useful in extending the operational lifecycle of nuclear power plant units and facilities with long operational lifecycle (30 years or more). The applied method of nondestructive evaluation provides control of critical components at different spectra of seismic impacts. The proposed methodology is based on experience of vibration and shock resistance testing of equipment in a certified test center of the NSC "Institute of Metrology" in the period from 1970 to 2015.
