Effect of Grain Boundaries on Krypton Segregation Behavior in Irradiated Uranium Dioxide

Fission products, such as krypton (Kr), are known to be insoluble within UO 2 , segregating toward grain boundaries and eventually leading to a lowering in thermal conductivity and fuel swelling. Recent computational studies have identified that differences in grain boundary structure have a signifi...
