Abstract

A method of integrating the level 1 and level 2 PSA model using the large event tree approach is presented. The treatment of the plant damage states is discussed. The linked model can switch between the level 1 and level 2 modelling by selecting different master frequency files. Multiple release categories can be calculated. Importance analysis and uncertainty analysis can be performed for the core damage frequency and frequency of release categories.
