Abstract

Base irradiation of the assembly IFA-148 and transient tests carried out by the Risoe Fission Gas Project on single pins from this assembly are analyzed using the URANUS code. The predicted gas release under normal operating conditions (base irradiation) and after an increase in power at the end of life (bump test) is compared with the experimental data obtained by puncturing the fuel pin or by non-destructive plenum spectrometry and by electron probe microanalysis which gives local gas retention data from which release levels may be deducted. Fair agreement exists between the experimental data and the theoretical results.
