Description

[Automatically extracted and translated] The paper discusses the prediction of cesium and krypton release from spherical fuel elements irradiated in the FRJ2-K15 experiment. The objective was to achieve a maximum heavy metal burnup of about 16% FIMA at different irradiation temperatures. Predictive calculations were made regarding fission product release in potential accident simulation experiments at the KÜFA test facility. The study utilized the PANAMA-I particle failure model and the FRESCO-II diffusion model to perform the predictions.

Abstract (German)

[Automatisch extrahiert und übersetzt] Dieser Bericht behandelt die Vorhersage der Freisetzung von Cäsium und Krypton aus kugelförmigen Brennelementen, die im Experiment FRJ2-K15 bestrahlt wurden. Ziel war es, einen maximalen Schwermetallabbrand von etwa 16% FIMA bei unterschiedlichen Bestrahlungstemperaturen zu erreichen. Vorhersageberechnungen wurden hinsichtlich der Freisetzung von Spaltprodukten in potenziellen Unfallsimulationsexperimenten an der KÜFA-Testanlage durchgeführt. Die Studie nutzte das PANAMA-I-Partikelversagensmodell und das FRESCO-II-Diffusionsmodell zur Durchführung der Vorhersagen.
