Abstract
In this paper, integrated dynamic and probabilistic
safety analysis (IDPSA) modelling is demonstrated using a
steam explosion case and the new FinPSA 2.0 tool for PRA
level 2 analysis. In the case study, a simplified level 2
model containing steam explosions was constructed for a
boiling water reactor nuclear power plant. Supporting
analyses were performed using deterministic computer code
MELCOR to gather knowledge on timings of events and
initial conditions for the fuel-coolant interaction
phenomena. The results of deterministic analyses were
incorporated into a probabilistic containment event tree
(CET) model. The level 2 method implemented in FinPSA is
based on dynamic CETs and CETL programming language. The
CETL is used to define functions to calculate conditional
probabilities of CET branches, timings of the accident
progression and amounts of releases.
