Computation of temperature and velocity fields in fuel elements of fast sodium-cooled breeders passed by a parallel flow
Description
A factor of decisive importance for the safe operation of nuclear reactors is the knowledge of the precise temperature distribution in the fuel elements. This study is to improve the computation of velocity and temperature fields in hexagonal fuel elements passed by a sodium flow. For this purpose, the turbulent transport phenomena in the turbulent bundle flow and their repercussions on the velocity and temperature fields had to be investigated. The ARTIS computer program was developed for calculation of the velocity and temperature fields; its results are compared with four different experiments. (orig.)

Fuer den sicheren Betrieb von Kernreaktoren ist die Kenntnis der genauen Temperaturverteilung in den Brennelementen von entscheidender Bedeutung. Mit dieser Arbeit sollte die Berechnung von Geschwindigkeits- und Temperaturfeldern in hexagonalen natriumdurchstroemten Brennelementen verbessert werden. Dazu mussten die turbulenten Transportvorgaenge in der turbulenten Buendelstroemung und ihre Wirkung auf das Geschwindigkeits- und Temperaturfeld untersucht werden. Zur Berechnung des Geschwindigkeits- und Temperaturfeldes wurde das Rechnenprogramm ARTIS entwickelt und seine Ergebnisse mit vier verschiedenen Experimenten verglichen. (orig.)
