Study of Creep and Hydride Re-Orientation Behaviour in E110 Fuel Cladding at Dry Storage Conditions

Original language description

Zirconium based alloys are commonly used as material for fuel claddings in the light water reactors. Claddings act as first metallic barriers against loss of fission products during the nuclear power plant operation, intermittent storage or final dry storage. During the reactor operation, claddings are subjected to different stress levels at high temperatures as well as neutron radiation. This results in their creep and the integrity of claddings is always critical issue for the safe performance of the power plants and storage. In this work, E110 cladding creep behaviour at dry storage conditions having different hydrogen levels is studied. Test specimen was oxidized in an autoclave to have desired hydrogen content. Creep test was performed in a horizontal furnace with internal pressure by applying thermo-mechanical cycle. The failure of the fuel cladding occurred by extensive ballooning and wall thinning. Optical and transmission electron microscopy investigations were made on creep tested specimen to study the deformation process and identify the mode of deformation. The examination of samples from the deformed regions showed formation of dislocations, secondary precipitate particles and precipitation of hydrides on the grain boundaries. Creep deformation was associated with the grain boundary sliding.
