Cladding corrosion, embrittlement and pellet clad interaction: proceedings of theme meeting

There is a worldwide trend in nuclear industry to extend the discharge burnup of fuel assemblies in nuclear power reactors. Irradiation of fuel to higher burnup will cause large degradation in properties of fuel and cladding material, which may limit the life of fuel pins. In order to develop computer codes to reliably predict fuel performance at extended burnup, understanding of the phenomena underlying the high burnup effects is essential. Important high burnup effects which can strongly influence the performance of fuel pin include enhanced release of gaseous and volatile fission products, pellet-cladding interaction, degradation of fuel thermal conductivity, rim formation, corrosion of cladding and clad lift-off due to high internal gas pressure. Cladding, corrosion, embrittlement and pellet clad interaction are discussed. Papers relevant to INIS are indexed separately
