Fission gas
WebIt was found that fission gas (133Xe) released from a specimen by fission fragment recoil is mostly captured in the wall of the irradiating capsule or in the capsule support material. The amount of fission gas released into the void space of the capsule is proportional to the surface area and to the fuel burn-up, and is controlled by a knock ... WebNov 6, 2024 · Modeling How Fission Gas Forms Bubbles on Grain Boundaries. Prudil then discussed a model created at Canadian Nuclear Laboratories that simulates how fission gas forms bubbles on the boundary of a single grain of uranium oxide, a process that involves fission gas products such as xenon and krypton. At the grain boundary, these …

WebDec 1, 2024 · Fission gas behavior and fuel swelling have always been an important issue for nitride fuels. In this paper, a mechanistic fission gas behavior model of nitride fuels has been established using the kinetic rate theory, based on the fuel temperature distribution input provided by a finite element computational platform. The fission gas release ... Webfuel may improve fission product gas retention and to provide enhanced resistance to stress corrosion cracking due to the pellet-clad interaction; fuels of high thermal conductivity reduce the heat stored in the fuel; microencapsulated fuels improve the fuel/cladding interaction and/or improve fission product retention.
