About the behavior of Zirconium hydride solid bodies under reactor irradiation

Description

This report documents the irradiation of Zirconium hydride samples produced by INTERATOM in the GETR of the General Electric Company. The material had the form of discs and cylinders and was irradiated with a neutron fluence of 1021 nvt (En≥1 MeV) at temperatures between 250 and 520 deg C. An average length change of 0.46 % was observed. Metallographical investigations showed, that the observed dimensional changes did not cause cracks or bubbles in the samples. The micro-structure remained intact. An influence of the irradiation on the hydrogen release rate could not be detected. The micro-hardness of one sample was determined. Its value agreed well with that of non-irradiated Zirconium hydride. The autoradiography of one sample showed a uniform distribution of the β- and γ-activity

Abstract (German)

In dem Bericht wird die Bestrahlung von Zirkonhydrid aus der Produktion der INTERATOM im GETR der General Electric Company dokumentiert. Das Material lag vor in Form von Ronden und Zylindern vor und wurde mit einer Neutronendosis von 1021 nvt (En≥1 MeV) bei Temperaturen zwischen 250 und 520 Grad C bestrahlt. Dabei wurde eine durchschnittliche Laengenaenderung von 0.46 % beobachtet. Anhand von metallographische Untersuchungen konnte gezeigt werden, dass die aufgetretene Dimensionsaenderungen keine Riss- oder Blasenbildungen in den Proben verursachen. Die Mikrostruktur blieb erhalten. Ein Einfluss der Bestrahlung auf die Wasserstoff-Austrittsrate konnte nicht festgestellt werden. An einer Probe wurden Mikrohaertebestimmungen durchgefuehrt. Die Werte stimmen gut mit denen von unbestrahltem Zirkonhydrid ueberein. Die Autoradiographie einer Probe zeigte eine gleichmaessige Verteilung der β- und γ-Aktivitaet
