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.
