Experimentally validated multiphysics modeling of fracture induced by thermal shocks in sintered UO pellets
Uranium Dioxide (UO) fuel powers almost all commercial Nuclear Power Plants (NPPs) worldwide, generating carbon-free energy and contributing to the fight against climate change. UO fuel incurs damage and fractures due to large thermal gradients that develop across the fuel pellet during normal and transient operating conditions. A comprehensive understanding of the underlying mechanisms by […]
