Description

The burnup of 17 fuel elements of the TRIGA Mark-II reactor in Vienna was measured. Different types of fuel elements had been simultaneously used for several years. The measured burnup values are compared with those calculated on the basis of core configuration and reactor operation history records since the beginning of operation. A one-dimensional, two-group diffusion computer code TRIGAP was used for the calculations. Comparison with burnup values determined by γ-scanning is also made. (orig./HP)

Abstract (German)

Das Verfahren wurde auf 17 Brennelemente des Reaktors TRIGA Mark II am Atominstitut Wien angewendet. Seit vielen Jahren sind dort Brennelemente verschiedener Typen gleichzeitig im Einsatz. Die gemessenen Abbrandwerte werden mit Berechnungen verglichen, die den Kernaufbau und die Betriebsgeschichte seit Erstinbetriebnahme beruecksichtigen. Dabei wurde das eindimensionale Zweigruppen-Diffusionsprogramm TRIGAP verwendet. Abschliessend werden die ermittelten Abbrandwerte auch mit Ergebnissen γ-spektroskopischer Messungen verglichen.
