DIFFUSION OF FISSION FRAGMENTS IN SLURRY FUEL ELEMENTS
Technical Report

OSTI ID:4347299
In an earlier memo. (A.E.R.E. T/M 93) an estimate of a few microns diameter was given as the maximum size of slurry particle from which fission products could escape into the liquid phase. The system considered was UPb/sub 3/ solid- Pb liquid at 600 deg C. The assumption that the diffusion rates of fission products are not much change by irradiation is investigated in detail, and also some of the other assumptions previously made about the particle stability of the slurry are discussed. The results of the previous memo. are confirmed; the main effects of irradiation which cannot be predicted are on the rates of sintering together of slurry particles and the bubbling which may result from rare gas release.
