Thermodynamic and Thermophysical Properties of the Actinide Oxides

New insights into the process of intrinsic point defects in PuO2

“…This indicates that the dominant defects in PuO 2 are Schottky defects, being consistent with the experiment. 8,10…”

“…3–6 This topic has been explored extensively by researchers, as highlighted in several studies. 1–11…”

“…Many researchers have investigated various physical and chemical properties of PuO 2 because it is considered the standard in plutonium reuse, separation, and permanent storage. [7][8][9][10][11] The redox properties of Pu-oxides are crucial to plutonium science and reactor safety because different oxidation states lead to different solubility levels, which can impact the chemical corrosion of the plutonium surface. [3][4][5][6] This topic has been explored extensively by researchers, as highlighted in several studies.…”

“…[3][4][5][6] This topic has been explored extensively by researchers, as highlighted in several studies. [1][2][3][4][5][6][7][8][9][10][11] There has been considerable research interest in stoichiometric PuO 2 ; however, studies on non-stoichiometric PuO 2 remain inadequate. 1,8 In reality, under various external environments, PuO 2 with a uorite structure is non-stoichiometric.…”

Uranium carbide oxidation from 873 K to 1173 K

“…The oxidation mechanism of UC is complex and affected by temperature, oxygen partial pressure, morphology of the oxide layer, oxide products, stoichiometry and process conditions [8]. Oxidation of UC was mostly investigated in the 1960s and 1970s when interest of UC as a breeder reactor material was high [9]- [14].…”
