The report is the Final Report on a research program whose objectives are to measure absolute spectral radiances from uranium-oxygen mixtures. The measurements are made under controlled conditions of temperature and species concentrations, and include infrared data. The experimental plan was to produce an aerosol of uranium in a controlled mixture of oxygen and inert gas such as argon. This aerosol is shock-heated, thereby vaporizing the metal particles, and providing a gaseous mixture of U, O2 and argon at high, equilibrium temperatures. The final data comprise absolutely measured spectral radiances over wavelength regions of interest. The parameters of the experiment are the temperature, relative UO2 ratios and wavelength range and resolution. Supporting measurements were conducted during the course of the program. The objectives of these studies included a the application of the exploding-wire aerosol shock tube technique to infrared radiance measurements of metallic oxides, b studies of the generation and spatial distribution of the uranium aerosols, c relevant species concentration measurements. A supporting theoretical effort involved the use of best available data to provide thermodynamic functions of uranium atoms and oxide molecules.
