This paper clarifies the seismic adequacy of installed equipment and electrical cable raceways in operating WWER 1000 type NPP:

The qualification approach is a combination of numerical analyses and GIP methodology in consideration of some specific features of WWER equipment, taking into account the as-built conditions and plant specific floor response spectra.

As result of the study the selected equipment is divided into 2 groups – equipment and cable raceways that are seismically qualified for Review Level Earthquake, equipment and cable raceways which require seismic upgrading.
