Description

Automatic translation: This report summarizes the essential data on the design, irradiation and follow-up investigation of the two irradiation experiments BR2-P21 and BR2-P22. The investigations were carried out on (Th,U)O2 TRISO particles of type E0 819/820 and (Th,U)O BISO particles with Al2O3, SiO2 core additives of type E0 898 with N valuesof 25 for the two-particle system (separation into brood and burn-up particles). The aim of the experiments, the determination of the damage rate, could only be achieved to a limited extent. Firstly, because the test specimens (rods) available had unfavorable initial conditions due to their manufacture and the intended temperatures were exceeded during irradiation due to thermocouple failure; secondly, because the follow-up investigation methods did not allow a more precise evaluation.

Abstract (German)

In diesem Bericht wurden die wesentlichen Daten über Auslegung, Bestrahlung und Nachuntersuchung der beiden Bestrahlungsexperimente BR2-P21 und BR2-P22 zusammengefasst. Untersucht wurden (Th,U)O2 TRISO-Partikeln der Sorte E0 819/820 und (Th,U)O BISO-Partikeln mit Al2O3-, SiO2-Kernzusätzen der Sorte E0 898 mit N-Werten von 25 für das Zweipartikelsystem (Trennung in Brut- und Abbrandpartikeln). Das Ziel der Experimente, die Schadensquotenbestimmung, konnte nur bedingt erreicht werden. Einmal, weil durch die zur Verfügung stehenden Prüflinge (Rods) aufgrund ihrer Herstellung ungünstige Ausgangsbedingungen vorlagen und während der Bestrahlung durch Thermoelementausfall die vorgesehenen Temperaturen überschritten wurden; zum anderen, weil die Nachuntersuchungsmethoden eine genauere Auswertung nicht zuließen.
