Thermal diffusivity measurements of irradiated oxide fuels (LWBR Development Program)
Technical Report
·
OSTI ID:6734444
The effects of irradiation on the thermal conductivity of ThO/sub 2/-UO/sub 2/ fuels were investigated. It appears that irradiation at a temperature of about 725/sup 0/C resulted in damage to the lattice that was manifested by a relatively large decrease in thermal diffusivity and thermal conductivity. However, these data are considered to be inconclusive because of the possibility that the presence of large, nonuniformly distributed pores in the specimens influenced the measurements in an unpredictable manner. Irradiation at a temperature of 980/sup 0/C had no significant effect on thermal conductivity. Apparently any radiation damage to the lattice was annealed out at this temperature in-pile.
