Description
The concentration of retained xenon, the percentage of porosity and the grain size have been measured as a function of radial position in the base irradiated rod AG11-8 and the transient tested rod AG11-10. The results show that in the base irradiation, densification of the fuel took place, no detectable gas release occurred and that slight grain growth occurred at the pellet centre. During the transient test, 15-20% of the xenon inventory was released from the fuel grains. Gas release was accompanied in the central region of the fuel by an increase in the porosity from 4.7% to 6-8%. These findings are compared with predictions made by the fuel performance code TRANSURANUS. The code predictions are in good agreement with the experimental observations.
