Pressure waves caused by Molten Fuel-Coolant Interaction (MFCI)

Creators

Description

Molten Fuel Coolant Interaction (MFCI) may cause sudden pressure built up by rapid heat transfer. The computer programme BLAFCI which was created by incorporating an own MFCI-model into the hydrodynamic code BLAST-2 can calculate the formation and propagation of these pressure waves. This ability is demonstrated by calculating with this combined version a number of pressure peaks measured in SPERT experiments. (orig.)

Abstract (German)

Beim direkten Kontakt von geschmolzenem Brennstoff und Kuehlmittel koennen durch thermische Wechselwirkung (MFCI) Druckwellen ausgeloest werden. Entstehung und Ausbreitung dieser Druckwellen im Kuehlmittel lassen sich mit dem Rechenprogramm BLAFCI berechnen, das aus der Kopplung eines eigenen MFCI-Modells fuer Wasser mit dem hydrodynamischen Modell BLAST-2 hervorgegangen ist. Diese Moeglichkeit wird bei der Auswertung einiger SPERT-Experimente demonstriert. (orig.)
