Transient gas release from defect particles

Creators

Description

Automatic translation: Problem: The model for the transient gas release from defect particles should be based on baking tests on FRJ-2-P28 samples / 1 / im Temperature range below 2000 ° C on the applicability for UO2 fuel must be checked. To do this, the basis is initially the stationary release of the irradiation experiment (FRJ2-P28) evaluate to those obtained from FRJ2-P25 (HEU fuel) To verify material parameters / 2 / as well as the influence of the To examine the combustion for the release. Unsteady processes during temperature cycling should also be treated become.

Abstract (German)

Problemstellung: Das Modell zur transienten Gasfreisetzung aus Defektpartikeln soll anhand von Ausheizversuchen an FRJ-2-P28-Proben /1/ im Temperaturbereich unterhalb 2000°C auf die Anwendbarkeit für UO2 -Brennstoff überprüft werden. Hierzu ist als Basis zunächst die stationäre Freisetzung des Bestrahlungsversuchs (FRJ2-P28) auszuwerten, um die aus FRJ2-P25 (HEU-Brennstoff) gewonnenen Materialparameter /2/ zu verifizieren sowie den Einfluß des Abbrandes auf die Freisetzung zu untersuchen. Instationäre Vorgänge während der Temperaturzyklierungen sollen ebenfalls behandelt werden.
