Description

Since June 1974, tests have been made on a model containment to simulate loss-of-coolant accidents in a multiply subdivided full-pressure containment. In the present work, experimentally determined results of the main tests C1 to C5 with the computer programmes ZOCO VI, DDIFF and the newly developed computer programme COFLOW, are compared. The study is to show that the instationary flow-mechanical processes in the starting phase of blowdown, i.e. the dynamic effects of the two-phase two-component flow, must not be neglected in the determination of the dynamic pressure differences in a multiply subdivided full-pressure containment.

Abstract (German)

An einem Modellcontainment werden seit Juni 1974 Versuche durchgefuehrt, die Kuehlmittelverlustunfaelle in einem vielfach unterteilten Volldrucksicherheitsbehaelter simulieren. In der vorliegenden Arbeit werden experimentell ermittelte Ergebnisse der Hauptversuche C1 bis C5 mit den Rechenprogrammen ZOCO VI, DDIFF und dem neu entwickelten Rechenprogramm COFLOW verglichen. Die Arbeit soll zeigen, dass die instationaeren stroemungsmechanischen Vorgaenge in der Anfangsphase des Blowdowns, d.h. die dynamischen Effekte der Zweiphasen-Zweikomponentenstroemung, in einem vielfach unterteilten Volldrucksicherheitsbehaelter zur Bestimmung der dynamischen Druckdifferenzen nicht vernachlaessigt werden duerfen.
