    Abstract

    Implementation of Quantitative Fire Risk Assessment in PSA (FIRAS) project aimed at application of flame spread modelling on real NPP situations, integration of the quantitative fire risk assessment methods into the NPP fire PRA, and carrying out fire simulations related to but outside OECD PRISME-project aiming to (i) guidance for the design of experiments and (ii) validation of the developed fire models. The main results include the improved and validated capabilities to predict flame spread on solid materials, methods to estimate the model parameters from small scale experiments, a quantitative method for the assessment of human actions affecting the safe-shutdown probability, and the assessment of fire spreading and second sub-system failures in a real NPP cable tunnel.
