Recent inelastic neutron scattering measurements of single crystal ThO2, including the linewidth and dispersion are reported as a function of temperature. Comparisons with simulation results and the iso-structural UO2 dispersion and linewidths are made. Special interest will be given to the resulting thermal conductivity as a function of temperature.
