PROBABILISTIC ANALYSIS OF THE FRAGILITY OF REACTOR BUILDINGS ON THE IMPACT OF EXTREME CLIMATIC LOADS

Abstract

: This paper gives the results of the probabilistic analysis of the nuclear power plants safety in Slovakia. The 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 10 4 years using the Monte Carlo simulations. There is showed summary of calculation models and calculation methods for the probability analysis of the structural resistance. The numerical simulations on the base of the LHS method were realized in the system ANSYS and FReET.
