NPP buildings and components seismic stability analysis in the frame of the standardized technique

Rough estimation of reliability of NPP component and equipment operation (probabilities of unfailing) during earthquakes according to the linear-spectral theory of seismic stability is suggested. The given technique allow to take into account, when estimating reliability of equipment and component operation, randomness of a great amount of factors determining structural strength, such as: parameters of seismic and other effects, deformation and strength properties of material and structures, different modes of equipment operation, conditionality of calculation diagram etc. The technique give possibility to detect resorces of load-carrying structures and to decrease specific consumption of structure materials providing the required level of their reliability
