Fission gas
WebGaseous fission products are produced during reactor operation, notably iodine (in elemental form and as methyl iodide), krypton, and xenon. Accidental leakage of these gasses could occur from the reactor core or primary coolant circuit during operation. WebJul 27, 2024 · Fission gas release is affected by fuel burnup, pellet porosity and temperature, but there is no complete and accurate mechanistic models to describe the fission gas release in UN fuel. The empirical relationship proposed by Storms ( Storms, 1988) through summarizing 134 sets of nitride fuel rod data is used here:

WebNov 1, 2010 · A number of gases are produced during the fission process of uranium and plutonium. The most important ones are helium, krypton, and xenon, which make up about 15% of the total fission products. Xenon and krypton are direct products of fission, while helium is mostly produced from the α-decay of fission products or transuranics (TRU).
