A detailed analysis of hyperstoichiometric carbide fuel, which operated under sodium-bonding conditions up to 12.5 at.% burnup in the Rapsodie reactor, yields the description of the four contributions to geometric fuel swelling as functions of temperature and burnup: (a) solid fission products and cesium, (b) fission gas swelling, (c) coarse porosity, and (d) the sum of all direct and indirect statistical swelling effects arising from the fracturing of the pellets. Fission gas swelling has to be separated into the contributions of three bubble populations and gas in solution. Between 7 and 11 at.% burnup, the relative amounts of the four swelling contributions are about the same and do not vary with burnup.
