Screen Test of Tritium Recovery from Stainless Steel Type 316

Various techniques, such as wiping, gas-purge at elevated temperatures, heating by flame simultaneously with air-purge, have been tested for decontamination of stainless steel samples exposed to tritium-containing hydrogen at room and elevated temperatures. Effectiveness of the decontamination techniques is compared depending on the history of the sample loading with tritium, treatment after the loading, the sample thickness, etc.
