From the journal Kerntechnik


The reactor dynamics code DYN3D being developed at the Helmholtz-Zentrum Dresden-Rossendorf is currently under extension for Sodium cooled Fast Reactor analyses. This paper provides an overview on the new version of DYN3D to be used for SFR core calculations. The current article shortly describes the newly implemented thermal mechanical models, which can account for thermal expansion effects of the reactor core. Furthermore, the methodology used in Sodium cooled Fast Reactor analyses to generate homogenized few-group cross sections is summarized. The conducted and planned verification and validation studies are briefly presented. Related publications containing more detailed descriptions are outlined for the completeness of this overview.


Der vom Helmholtz-Zentrum Dresden-Rossendorf entwickelte Reaktordynamik-Code-DYN3D wird derzeit auf die Anwendung für schnelle Reaktoren erweitert. Dieser Artikel gibt einen Überblick über die neue Version von DYN3D, die für Kernrechnungen von natriumgekühlten Reaktoren angewendet werden soll. Der vorliegende Artikel beschreibt kurz die neu implementierten Modelle für die Modellierung der thermischen Ausdehnungseffekte des Reaktorkerns. Weiterhin ist die Methodik der Erzeugung von homogenisierten Wenig-Gruppenwirkungsquerschnitten für natriumgekühlte schnelle Reaktoren zusammengefasst. Die durchgeführten und geplanten Verifikations- und Validierungsstudien werden kurz vorgestellt. Zur Vervollständigung des Überblicks werden die entsprechenden ausführlichen Publikationen kurz dargestellt.
