This probabilistic assessment of NPP structures for Probabilistic Safety Analysis (PSA) level 2 of VVER 440/213 in the case of the extreme external even without the earthquake is presented. On the base of the meteorological monitoring of the locality, the extreme load parameters were defined for the return period 104 years using the Monte Carlo simulations. There is showed a summary of calculation models and calculation methods for the probability analysis of the structural resistance. The general purpose of the nonlinear probabilistic analysis of the NPP structure resistance was to define the safety level of the critical structural elements. The numerical simulations on the base of the LHS method were realised in the system ANSYS and FReET.
