Abstract

Irradiation experiments are reported with HTR fuel elements within the AVR reactor. It is shown how to charge fuel elements onto the core to detect them by the burnup measurement facility exactly after passing the inner part of the core one time. So these fuel elements could be discharged directly. The method of chemical dissolution of the fuel elements is presented and the results of the mass spectrometric analysis are reported. The analysis by calculation with the reactor simulation program HTR-2000 is described. The results are listed and discussed. The comparison between the experimental and computed outcomes gives a good agreement.
