Tritium transport in single crystal LiAlO{sub 2}
Technical Report
·
OSTI ID:139241
Tritium transport in LiA10{sub 2} has been studied by performing isothermal anneals followed by sectioning of the sample to determine the tritium concentration profiles within the sample. The anneals were performed over the 528 to 783{degrees}C temperature range under a He + 0.1%H{sub 2} purge gas flow. The results indicate that: (1) tritium diffusion in LiA10{sub 2} is fast, and is not sensitive to impurities, and (2) tritium release for these samples is in the mixed diffusion-desorption regime. For samples with a grain size of 100 {mu}m or less, the tritium release will be desorption controlled.
