Catalysis of graphite corrosion literature review
Description
Automatic translation: 1. Introduction and summary: Fuel elements from the AVR, from the extraction group 27, and in experiment DRK4 irradiated BE showed increased corrosion rates in the standard corrosion test, often associated with pitting. The changed corrosion behavior is probably due to impurities that are responsible for the reaction of graphite with steam have a catalytic effect. The necessary investigations will be carried out ad hoc Perform group pell effect. In the first phase of the work program, the present literature compilation an overview indicate which elements are eligible as catalysts also some results of pitting investigations are given.
Abstract (German)
1. Einführung und Zusammenfassung: Brennelemente aus dem AVR, von der Entnahmegruppe 27 an, und im Experiment DRK4 bestrahlte BE zeigten im Standardkorrosionstest zum Teil erhoehte Korrosionsraten, oft verbunden mit Lochfraß. Das veränderte Korrosionsverhalten rührt wahrscheinlich von Verunreinigungen her, die für die Reaktion von Graphit mit Wasserdampf katalytisch wirken. Die notwendigen Untersuchungen wird die ad-hoc Gruppe Pelleffekt durchführen. In der ersten Phase des Arbeitsprogrammes soll die vorliegende Literaturzusammenstellung eine Uebersicht geben, welche Elemente als Katalysatoren in Frage kommen, außerdem werden einige Ergebnisse von Lochfraßuntersuchungen angegeben.
