Abstract:

The thermal conductivity of zirconium hydride was investigated at temperatures 100 to 800 C and with varying H content. Specimens with four different H contents were used, corresponding to N sub H where N sub H is 10 to the -22nd power times the number of H atomscc equal 2.16 to 4.13 for three unclad specimens and to N sub H equals 4.41 for one clad specimen. The measurements were made with an apparatus employing steady-state longitudinal heat flow in a rod of zirconium hydride surrounded by a guard tube with matching temperature gradient to minimize radial heat loss. In addition to the thermal conductivity measurements, electrical conductivity measurements of some of the specimens were made. Author
