This paper describes the reliability analysis of concrete bubbler tower structure for VVER 440 under high internal overpressure. There is showed summary of calculation models and calculation methods for the probability analysis of the structural integrity considering degradation effects and high internal overpressure. The non-linear analysis of the concrete structures was realized. The uncertainties of the loads level (long-time temperature and dead loads), the material properties (concrete cracking and crushing, reinforcement, and liner), degradation effects and other influences following the inaccuracy of the calculated model and numerical methods were taking in the account in the RSM method, which is based on the approximation of the Monte Carlo simulations.
