| Abstract Scope |
High-density fuels (HDF) are nuclear fuels that contain a higher uranium density than traditional uranium dioxide. Research of HDF focusing on the oxidation of U<sub>3</sub>Si<sub>2</sub>, UN, UC, and UB<sub>2</sub> in air, water, and steam environments concluded uranium forms UO<sub>2</sub> and U<sub>3</sub>Si<sub>2</sub> forms a hydride. However, minimal research has been done on the interaction between HDF and hydrogen. Typical oxidation characterization involves using XRD and SEM images which can be difficult in detecting hydrogen absorption. The Sieverts technique is implemented in the present study to detect hydrogen absorption by monitoring pressure drops during the hydrogen interaction with HDF. The results presented cover a temperature range from 100 to 500 °C in up to atmospheric pressures for 24-96 hour dwells. Additionally, a LECO instrument is used for elemental analysis of the hydrogen content after testing. The presented data will be discussed in relation to LWR fuel performance interactions with hydrogen containing atmospheres. |
