Release of solid fission products from BE of AVR

Creators

Description

Automatic translation: 1st task: To verify the calculation models (GETTER program) is intended to calculate the release of Cs 137 from the AVR core and compared with measurement results. There are measured Concentration profiles of fission and activation products in the shells of discharged fuel assemblies and concentration measurements in the hot gas at the core outlet of the AVR (VAt-1PIR I). Using the example of the Cs137, in particular investigated whether the growing to the fuel element surface Profiles with the measured partial pressure in the cooling gas can be explained.

Abstract (German)

1. Aufgabe: Zur Verifikation der Berechnungsmodelle (Programm GETTER) soll die Freisetzung von Cs 137 vom AVR-Kern berechnet und mit Meßergebnissen verglichen werden. Dafür liegen gemessene Konzentrationsprofile von Spalt- und Aktivierungsprodukten in den Schalen von ausgeschleusten Brennelementen und Konzentrationsmessungen im Heißgas am Kernaustritt des AVR (VAt-1PIR I) vor. Am Beispiel des Cs137 soll insbesondere untersucht werden, ob die zur Brennelement-Oberfläche anwachsenden Profile mit dem gemessenen Partialdruck im Kühlgas erklärt werden können.
