Type: conference-paper
Abstract: High temperature deformation behaviour of irradiated Zircaloy-2 cladding has been studied by carrying out isothermal heating of irradiated PHWR fuel pins, having burnup up to 15000MWd/tU at 700°C -900°C inside the hot-cells.Post-test examination included visual examination, leak testing, dimension measurement on the tested fuel pins and optical and SEM examination of cladding sections taken from the ballooned and failed fuel pins.The specific aspects investigated in these experiments included cladding tube deformation and ballooning-failure as a function of cladding temperature, internal gas pressure and burn up of the fuel pin and microstructural aspects of high temperature creep deformation and mode of cladding failure.
