Investigations of aerosol formation in the HAW vitrification process

Creators

Description

Aerosol production during the vitrification process of high-level waste was simulated in a laboratory scale to increase the knowledge of the basic production mechanisms. Elemental composition, size distribution and production kinetics of the aerosols as well as the structure of individual particles were investigated. A comparison with the PAMELA vitrification plant was performed to check the validity of the results in a technical scale. (orig.)

Abstract (German)

Die Aerosolbildung bei der Verglasung des hochradioaktiven Abfalls bei der Wiederaufarbeitung (HAW) wurde in Laborexperimenten simuliert, um die Kenntnisse ueber die massgebenden Entstehungsmechanismen zu erweitern. Es wurden Elementzusammensetzung, Groessenverteilung und Austragskinetik der Aerosole bestimmt sowie Strukturuntersuchungen an Einzelpartikeln durchgefuehrt. Die Ergebnisse der Laborexperimente wurden mit Untersuchungen in der PAMELA-Verglasungsanlage verglichen und auf ihre Uebertragbarkeit in den technischen Massstab ueberprueft. (orig.)
