Evaluation Calculations for the Dragon - Ball Radiation Experiments DR-K4 and DR-K5
Description
Automatic translation: For the sphere irradiation experiments DR-K4 and DR-K5, which are in the were carried out in the DRAGON reactor between 1970 and 1974, Nuclear and thermal recalculations were carried out with the aim of creating a basis for the thermal analysis of fission product transport and release rates. The DR-K4 has good thermal reproducibility of the relevant measured values was achieved, while with DR-K5 there were clear deviations between the calculated and measured gas temperatures, especially for the first irradiation period. The reason for these discrepancies is most likely to be found in the strong thermal coupling between the experiment and the driver elements.
Abstract (German)
Für die Kugelbestrahlungsexperimente DR-K4 und DR-K5, welche in den Jahren 1970 bis 1974 im DRAGON-Reaktor durchgeführt worden sind, wurden nukleare und thermische Nachrechnungen vollzogen mit dem Ziel, eine Basis für die thermische Analyse des Spaltprodukttransportes und der Freisetzungsraten zu erstellen. Bezüglich des DR-K4 wurde eine gute thermische Reproduzierbarkeit der relevanten Meßwerte erreicht, während sich bei DR-K5 insbesondere für die erste Bestrahlungsperiode deutliche Abweichungen zwischen den berechneten und gemessenen Gastemperaturen ergaben. Die Ursache für diese Diskrepanzen ist sehr wahrscheinlich in der starken Wärmekopplung zwischen dem Experiment und den Drverelementen zu finden.Files
