Abstract

The work presents the RSM modelling approach for uncertainty analysis in probabilistic risk assessment. Such approach introduces in the present context some interesting aspects: - it enables one to perform a more accurate tuning of the stages of the accident process in the evaluation of the risk and hence is a step forward in respect to the classical probabilistic risk assessment; - it requires the use of models which reproduce even roughly the mechanisms of the accident; - it draws attention to the need for a different quality of information on the physics of the accident process. As an example data about pressure in the system or in the pressurizer, about temperature and other variables during a normal transient in a nuclear power plant.
