Abstract

The distribution of xenon and caesium in a water reactor fuel pellet has been measured by electron probe microanalysis. The fractional xenon release was found to be 14 % at the pellet ends compared with 28 % at the mid-pellet position. At the mid-radial position, the concentration of retained xenon decreased sharply within 1 mm of the pellet ends after which it did not change significantly. The axial concentration profile for caesium exhibited a similar trend to that of xenon.
