Analysis of Transients and Accidents with the System Code ATHLET for the Krško Nuclear Power Plant

Main aspects of the cooperation between the Republic of Croatia and the F.R. of Germany in the field of NPP safety research are overviewed in the paper. The GRS system code ATHLET developed for the analysis of anticipated and abnormal plant transients, small and intermediate leaks as well as large breaks in light water reactors is now being available at the University of Zagreb. A very comprehensive ATHLET standard input data set for the NPP Krško has been established. This data set was validated by calculation of the event 'Main Steam Isolation Valve Closure' that occurred at the PWR NPP Krško in 1995 and comparing the resulting characteristic parameters with the corresponding measured data.
