Description

The source terms for fission product releases (gaseous, lift-off aerosols, wash-off aerosols) from a HTR pressure vessel are estimated for different types of LOCA. Typical accident conditions are discussed using the example of 131I, and fission product sources for aerosols and gases are discussed. Fission product releases are characterized by the aerosol-specific parameters, i.e. activity and chemical bonding state. (orig./DG)

Abstract (German)

Die Quellterme fuer aerosolgebundene (Luft-Off- und Wash-Off-Aerosole) und gasfoermige Spaltprodukt (SPP)-Freisetzungen aus dem RDB des HTR-Modul werden fuer verschiedene Stoerfaelle mit Kuehlmittelverlust abgeschaetzt. Stoerfalltypische Bedingungen werden am Beispiel des I-131 diskutiert und die verschiedenen SPP-Quellen fuer Aerosole und Gase analysiert. Die SPP-Freisetzungen werden durch die aerosolspezifischen Parameter, Aktivitaet und chemischer Bindungszustand charakterisiert. (orig./DG)
