The modelling in fuel behaviour codes that are in use at
VTT has been subject to extensive upgrading in a number
of respects. Major achievements include: 1) Streamlining
of the coupling of the advanced thermal hydraulic module
GENFLO with successive versions the FRAPTRAN fuel
performance code, and vivid application of the tool the
Halden Project IFA-650 LOCA test series. 2) Comprehensive
renewal and extension of the mechanical modelling in
FRAPCON and FRAPTRAN codes. 3) Demonstration of joining
two programming cultures, the conventional FORTRAN 77 in
the VTT version of the ENIGMA code and a module with an
Object-Oriented Programming approach of the IMAGINE code
and validation. 4) Recorrelation of the parameters of the
fission gas model in the ENIGMA code with data from 108
measurements. 5) Basis for a probabilistic procedure to
fuel accident behaviour analyses. 6) Favourable progress
in education and training of a new generation of experts.
