X-RAY SPECTRAL MICROPROBE ANALYSIS OF XENON IN IRRADIATED FUEL FROM THERMAL REACTORS

摘要

The radial dependences of the xenon production and content in fuel irradiated to maximum burnup 70 MW·days/kg are presented. The maximum local burnup for the onset of restructuring of fuel in the rim zone, the dependence of the width of the zone of restructuring on the average burnup over the cross section of a pellet, and the residual content of xenon in completely restructured fuel are determined.
