Abstract
FINIX is a recently developed fuel behaviour module that
is designed to provide "simple but sufficient"
descriptions of the most essential fuel behaviour
phenomena in multiphysics simulations. In such
simulations, it is possible to obtain significant
improvement in the feedback to neutronics or thermal
hydraulics modelling even with a relatively simple fuel
performance model. In this work, FINIX is used as an
internal fuel behaviour module both in reactor physics
and in reactor dynamics codes to simulate coupled
behaviour in fast transient scenarios. With the Monte
Carlo reactor physics code Serpent we model a prompt
transient in a VVER-1000 pin cell, and with the reactor
dynamics code HEXTRAN, a control rod ejection accident in
a VVER-440 reactor.
