Description
More recent results have been made available of seizing (selfwelding) and wear experiments under sodium which are important for the choice of suitable SNR distance pad materials. The influence of gas bubbles on the temperature distribution of a surface under high thermal load (fuel pins and blanket pins) in a sodium flow was studied in a first series of water experiments. Reports are available on the continuation of design studies of large sodium breeders and helium breeders. For the SNR 2 core the influence of the most important core parameters on various economical criteria was investigated and a provisional reference core was suggested on the basis of these studies. Safety problems are being discussed for the design draft of a 1,000 MWe gas cooled breeder. (orig.)
Abstract (German)
Von Verschweiss- und von Verschleissversuchen unter Natrium liegen neuere Ergebnisse vor, die fuer die Auswahl geeigneter SNR-Distanzpflasterwerkstoffe von Bedeutung sind. Der Einfluss von Gasblasen auf die Temperaturverteilung einer thermisch hochbelasteten Oberflaeche (Brennstaebe und Brutstaebe) in Na-Stroemung wurde in einer ersten Serie von Wasserversuchen studiert. Es liegen Berichte ueber den Fortgang von Entwurfsstudien fuer grosse Na-Brueter und He-Brueter vor. Fuer den Kern des SNR 2 wurde der Einfluss der wichtigsten Kernparameter auf verschiedene Wirtschaftlichkeitskriterien untersucht und daraufhin ein vorlaeufiger Referenzkern vorgeschlagen. Fuer den Entwurf eines 1.000 MWe Gasbrueters werden Sicherheitsfragen diskutiert. (orig.)Additional details
