Annotation:

The article is devoted to taking into account random factors when an aircraft impact is included in the design basis of a nuclear power plant (NPP). The fall of transport and high-speed military aircrafts in cases of unintentional (emergency) and deliberately organized (terrorist act) crash is considered. It is shown that in case of an unintentional fall, the impact of an aircraft into structures of ordinary sizes can be ignored due to the too low probability. Two methods of probabilistic setting of design loads on building structures are proposed. A technique for probabilistic setting of floor response spectra (FRS) is proposed, by means of which dynamic loads on technological equipment are calculated. It is shown that the probabilistic approach can significantly reduce the design loads while maintaining the safety of NPP. The procedure for determining the coefficients of combinations for summing up of the same name internal forces, calculated by three components of the FRS, is de­scribed
