Steam generator
Description
The flow conditions in a steam generator for a PWR, where the primary medium is passed through a U-tube bundle, are to be improved without increasing the flow resistance by providing a channel, narrowing towards the tube sheet, in the tube lane formed by the tube bundle. By this a forced afflux of feedwater, and also a better cooling of the tube sheet will be achieved. With the aid of a flow restrictor the distribution of the feedwater may be controlled. Datails of the design are described. (UWI)

Die Verbesserung der Stroemungsverhaeltnisse ohne Erhoehung des Stroemungswiderstandes in einem Dampferzeuger fuer einen DWR, bei dem das Primaermedium in einem U-Rohrbuendel gefuehrt wird, soll dadurch erreicht werden, dass in der vom Rohrbuendel eingeschlossenen Rohrgasse ein sich zum Rohrboden hin verengender Kanal vorgesehen ist. Man erreicht damit einen verstaerkten Zustrom von Speisewasser und auch eine bessere Kuehlung des Rohrbodens. Mit Hilfe einer Drossel kann die Verteilung des Speisewassers gelenkt werden. Die konstruktive Ausgestaltung wird beschrieben. (UWI)Files
