Relations have been derived from gas analyses of irradiated PyC‐coated UO 2 fuel particles that enable the quantity of permanent rare gas (Xe+Kr) released within the particle to be predicted from known conditions of irradiation temperature, time, and burnup. The experimentally determined influence of fissions in uranium and plutonium isotopes on the growth of intraparticle CO + CO 2 pressure is discussed and its elimination by an appropriate getter is described.
