Irradiation Experiment FRJ-2 - P16

[Automatically extracted and translated] The experiment FRJ2-P16 aims to contribute to the clarification of the amoeba effect. On the one hand, the kinetics of particle failure due to core-shell interaction with different core compositions, coatings, and temperatures are to be investigated. On the other hand, it is to be checked whether the carbide doping of oxide cores also causes stabilization of the oxygen potential of the cores at high burn-ups and thus a reduction in the susceptibility of these coated particles to the amoeba effect. During irradiation, R/B values between 1x10^-5 and 1.2x10^-2 were measured for the isotopes Kr85m, Kr87, Kr88, Xe133, and Xe135. The particle temperatures ranged between 1600°C and 960°C. A maximum burn-up between 7.4 and 12.0% fima was achieved. This report describes the irradiation in FRJ-2.
