Description
A remote controlled device has been developed for an internal heating experimental method in a hot-cell in order to evaluate the behavior of hydrogen and elucidate the formation mechanism of radially oriented hydrides in irradiated fuel cladding tubes. The device enables one to perform internal heating experiments under conditions of up to 300 W/cm with a linear heat rate and 209 MPa hoop stress. Quantitative analysis of the hydrogen content indicates thermal diffusion under the conditions used in this study. The radial orientation of hydrides remarkably appeared in the range from 235 W/cm to 295 W/cm after being constant in the range under 235 W/cm. The hoop stress slightly promoted the radial orientation of hydrides. (author)
