There is also one very important phenomenon that influences the fuel temperature. As the fuel burnup increases, the fuel-cladding gap reduces. This reduction is caused by the swelling of the fuel pellets and cladding creep. Fuel pellet swelling occurs because fission gases cause the pellet to swell, resulting in a larger … See more Claddingprevents radioactive fission products from escaping the fuel matrix into the reactor coolant and contaminating it.

Webdid not result in cladding creep failures. When a more realistic (though still conservative) decay gas release fraction based on data for helium release was assumed, which is conservative, the maximum creep strains accumulated were on the order of 0.54 % to 1.04 %, but creep failures are not expected below at least 2 % strain.
WebSignificantly less creep is ircaloy cladding experienced by the MA956 resulting in fuel-tothe-cladding gap remaining open for a longer duration leading to higher fuel temperatures. The inner cladding surface temperature remains relatively constant for both simulations.
