Actinide Oxide Dissolution in Tributyl Phosphate by Gogolski Jarrod, Goetzman Chelsea, Mills Matthew, Nguyen Vinh, Rudisill Tracy, Lascola Robert

“…The organic solution then goes through a solvent extraction process to recover the uranium and/or other desired radionuclides. This work qualitatively studied the dissolution of actinide oxides (UO2, NpO2, and PuO2) in tributyl phosphate using UV-Vis-NIR absorbance spectroscopy to ascertain dissolution behavior. …”

Analysis of Heat Release Processes inside Storage Facilities Containing Irradiated Nuclear Graphite by Alexander O. Pavliuk, Evgeniy V. Bespala, Sergey G. Kotlyarevskiy, Ivan Yu. Novoselov, Veleriy N. Kotov

“…The analysis of heat release processes inside storages containing irradiated nuclear graphite, representing a potential hazard due to the possible heating and, accordingly, the release of long-lived radionuclides during oxidation was carried out. The following factors were considered as the main factors that can lead to an increase in the temperature inside the storage facility: corrosion of metallic radioactive waste, the presence of fuel fragments, and also the random exposure of irradiated graphite to local sources of thermal energy (spark, etc.). …”
