3. DESCRIPTION

This experiment deals with the study of fission gas release and fuel swelling during power transient at medium burn up. The rod was base irradiated in a PWR and then re-irradiated in the test reactor SILOE in Grenoble France. Since the rod is initially a segmented rod. The refabrication process prior to loading in the test is minor. In particular, the rod is not purged of its fission gases following refabrication.
Segmented rod
  - UO2 4.5 % U5
  - Zy4 stress relieve
  - Pint 26 Bar
- Irradiation in PWR up to 47.415  MWd/kgM
  - Diameter measurement
  - Fission gas release measurement par non destructive Kr 85 gamma measurement : 1.5 %
- Experimental power ramp in SILOE :
  - Aquilon Device : 130 bar
  - Axial power profile determined by Zr95 gammascanning
  - Conditioning power step : 195 W/cm during 48 hours
  - 10 W/cm/mn up to 385 W/cm
  - duration of high power level : 1h30
