Semi-Annual Report I/92 to the Project Fuel Elements Under Normal and Accident Conditions
Description
Automatic translation: Fission product release from the core hangs in all Operating cases decisively depends on the temperature distribution of the fuel elements. Significant influencing variable for the temperature calculation is the thermal conductivity of the fuel assembly matrix material A3 on the temperature and the neutron fluence. the previously used database should be evaluated additional experiments to be improved to break down existing conservatives. As a base the data collection are the measurements on unirradiated to compile samples. The following investigations are planned for the reporting period: - Evaluation of the quality test data of the THTR fuel assembly Production related to thermal conductivity of A3-3 matrix material.
Abstract (German)
Die Spaltproduktfreisetzung vom Kern hängt in allen Betriebsfällen entscheidend von der Temperaturverteilung der Brennelemente ab. Wesentliche Einflußgröße für die Temperaturberechnung ist die Wärmeleitfähigkeit des Brennelement-Matrixmaterials A3 in Abhängigkeit von der Temperatur und der Neutronenfluenz. Die bisher verwendete Datenbasis soll durch Auswertung zusätzlicher Experimente verbessert werden, um die bestehenden Konservativitäten abzubauen. Als Basis der Datensammlung sind die Messungen an unbestrahlten Proben zusammenzustellen. Im Berichtszeitraum sind folgende Untersuchungen vorgesehen: - Auswertung der Qualitätsprüfdaten der THTR-Brennelement- Produktion bezüglich der Wärmeleitfähigkeit von A3-3 Matrixmaterial.
