ABSTRACT:
A nuclear fuel particle wherein a core, up to about 250 microns in diameter, of a normally solid fissionable material is completely encased in a shell having at least two concentric layers. A yielding of carbonaceous material about 5 to about 50 microns thick is disposed inward of a layer of substantially impermeable refractory material, e.g., pyrocarbon, up to about 100 microns thick. Examples of the yielding layer include carbonized synthetic polymer resins and sooty pyrocarbon.
