"The probabilistic safety assessment is a standardised tool for assessing and improving nuclear power plant safety. The probabilistic models of safety equipment, which represent the standpoint for evaluations, are based on assumption of constant failure rate. The probabilistic models are used within the fault trees, which represent the models of the systems. The fault trees are linked together with the event trees, which model the accident scenarios of the plant and which combine the systems together in an overall model. The new probabilistic safety assessment models, which include information about aging, are developed. The developed models are inserted into the models of the probabilistic safety assessment in order that the aging effects are considered. The results show a slight increase of risk considering the aging effects. At the same time, the results change the ordering of the most important equipment from aspect of risk decrease and risk increase factors."@en .
