This report is being issued within the COLOSS Project of 5th Framework EC Programme Key Action on Nuc1ear Fission. The results of 2nd set of TMI-2 calculations performed with an improved version of ICARE/CATHARE code and the new VI version of ASTEC code are presented.The ASTEC VI code includes the thermal-hydraulic CESAR module for the analysis of the primary and secondary systems, which is coupled to the DIVA module for core degradation analysis. Model improvements in ICARE/CATHARE code concern UO2 dissolution of irradiated fuel and oxidation of U-Zr-O relocated mixture.A sensitivity analysis has been performed with ICARE/CATHARE code to assess the influence of some important core degradation parameters on the hydrogen generation and the amount of formed me1ts.

Abstract

This report is being issued within the COLOSS Project of 5th Framework EC Programme Key Action on Nuc1ear Fission. The results of 2nd set of TMI-2 calculations performed with an improved version of ICARE/CATHARE code and the new VI version of ASTEC code are presented.The ASTEC VI code includes the thermal-hydraulic CESAR module for the analysis of the primary and secondary systems, which is coupled to the DIVA module for core degradation analysis. Model improvements in ICARE/CATHARE code concern UO2 dissolution of irradiated fuel and oxidation of U-Zr-O relocated mixture.A sensitivity analysis has been performed with ICARE/CATHARE code to assess the influence of some important core degradation parameters on the hydrogen generation and the amount of formed me1ts.
