Abstract
A methodology for evaluating the frequency of
severe consequences due to fires in nuclear power
plants is presented. The methodology produces a 1 of accident scenarios and then assesses the frequency
of occurrence of each. Its framework is given in
six steps. In the first two steps, the accident
scenarios are identified qualitatively and the potential
of fires to cause initiating events is investigated.
The last four steps are aimed at quantification.
The frequency of fires is obtained for different
compartments in nuclear power plants using Bayesian
techniques. The results are compared with those of
classical methods and the variation of the frequencies
with time is also examined. The combined effects of
fire growth, detection, and suppression on component
failure are modeled. The susceptibility of cables to
fire and their failure modes are discussed. Finally,
the limitations of the methodology and suggestions for
further research are given.
