Failure Probability of NPP Communication Bridge under the Extreme Loads

Abstract

Safety and reliability of the communication steel bridge of the nuclear power plant under extreme loads is considered in this paper. The extreme load from the wind and the earthquake is defined for the probability of exceedance 10-4 per year on the base of the last results from the investigation in Slovakia. The deterministic and the probabilistic assessments to verify the safety and reliability of the structure are presented. The uncertainties of the input data and the calibration of the load factors are discussed. The advantages and disadvantages of the probabilistic analysis are discussed. The advantages of the utilization the LHS method to analyze the safety and reliability of the structures is presented.
