Evaluation of Alternate Impurity Removal Getters - Year 2
- Savannah River Site (SRS), Aiken, SC (United States). Savannah River National Lab. (SRNL)
The Savannah River Site Tritium Facilities use various getter materials (SAES® ST909 and ST198) as part of the tritium process stripper (TPS) for the removal of impurity species. Benefits of ST909 are found in both environmental stewardship and gas processing improvements. The tritium capturing performance of ST198 is affected by impurities such as ammonia and carbon monoxide. SAES ST198 is used as a final polisher to remove trace amounts of tritium in the process stream before discharge through the stack. ST909 decomposes impurities such as tritiated water, methane, and ammonia. Therefore the upstream material, ST909, is important to environmental safety. ST909 also provides the benefit of capturing oxygen and carbon oxides.
