2020:02 Models for axial gas flow and mixing in LWR fuel rods
both during normal operation and during events and accidents. Fission gases are released from inside the fuel pellets to the gap between the pellet and the cladding tube and then flow to the plenum volume ... The presence of fission gases in the pellet-cladding gap is important for the rod internal pressure and for the pellet-cladding heat transfer. While these effects are considered in most computer codes for...
