Keywords: nuclear power plant, instrumental intensity, cumulative absolute velocity, peak ground acceleration, response spectra, earthquake damage, damage indicator, post-event assessment.
After an earthquake, the condition of systems, structures and equipment at nuclear power plants has to be assessed since this information is needed for accident management and to make decisions concerning the continuation of the operation. The damaging potential of the earthquake can be characterised by maximum horizontal acceleration of the ground motion, response spectra, cumulative absolute velocity and different instrumental intensity values. These quantities can be correlated to the earthquake characteristics, magnitude, distance, etc. Some of the indices are related to the damage mechanism and can be correlated to load-bearing features of the structures. Different indicators of the damaging potential of earthquakes are analysed in this paper from the point of view of applicability for post-event condition assessment at nuclear power plants and for use as criteria for the restart of operations.
