Using gamma spectrometry indicators to detect and quantify fission products changes in irradiated fuel
Résumé
A new analysis method based on gamma scanning of
fission products on irradiated rods is presented. Indicators
calculated from this method can be used for the qualitative
treatment and comparison of irradiated rods from PWR, SFR or
and MTR. Differences in the behavior of fission products (FP)
can thus be quantified. Phenomena such as migration or
geometrical changes in pellets should thus benefit from these
accurate, yet quickly and easily achievable results.
