Description

For the quantitative description of the radiation influence, the complex reaction of the highgrade steel/HNO3/Cr6+ system was first investigated in detail without the effect of radiation. For this purpose the individual influence of the following parameters on the corrosion rate was investigated and the results were summed up in a model: mass removal, chromate concentration, nitric acid concentration in the presence of Cr6+, temperature. Under the influence of the gamma radiation of an external Co-60 source, the mass removal curve to be calculated by the model is indirectly changed by the radiation-chemical reduction of the chromate. The influence of the beta radiation field can be ignored. (orig./RB)

Abstract (German)

Um den Strahleneinfluss quantitativ beschreiben zu koennen, wurde die komplexe Reaktion des Systems Edelstahl/HNO3/Cr6+ zuerst ohne Einwirkung von Strahlung eingehender untersucht. Hierzu wurde der Einfluss der nachfolgenden Parameter auf die Korrosionsrate einzeln untersucht und die Ergebnisse in einem Modell zusammengefasst: Massenabtrag, Chromatkonzentration, Salpetersaeurekonzentration in Gegenwart von Cr6+, Temperatur. Unter dem Einfluss der Gammastrahlung einer externen Co-60-Quelle wird die durch das Modell zu berechnende Massenabtragskurve indirekt ueber die strahlenchemische Reduktion des Chromats veraendert. Der Einfluss eines Beta-Strahlenfeldes ist hier vernachlaessigbar klein. (orig./RB)
