The goal of this Master's thesis will be to investigate the effects of oxidation under humid conditions in a variety of fine UO2 powders, at low temperatures. The candidate will need to prepare starting powders by applying both wet-chemical (dissolution, precipitation) and solid-state (drying, calcining) techniques. Characterization of these powders will consist of measuring specific surface area using the BET-method (N2 adsorption), assessing morphology via scanning electron microscopy (SEM), and analyzing the crystal structure via X-ray diffraction (XRD). The oxidation experiments will be performed and monitored in-situ using a simultaneous thermal analyzer (STA), which is capable to measure as a function of temperature changes in mass (thermogravimetry), reaction enthalpy (calorimetry), and evolved gasses (mass spectroscopy). All experimental work will be performed in the controlled areas of SCK•CEN, providing safe manipulation of chemical and radioactive materials, and in laboratories equipped with the above mentioned analytical techniques.
