Title: Thermolytic Hydrogen Generation Testing of Tank 22 Material

Abstract

Savannah River National Laboratory performed hydrogen generation rate (HGR) testing using Tank 22 actual-waste sample material. The main objective of the testing was to determine the thermolysis HGR for Tank 22 material with and without added glycolate. An important use of the data from actual-waste sample testing is to validate equations for the Savannah River Site Concentration, Storage, and Transfer Facility (CSTF) HGR being developed through simulated-waste testing. Not exclusive to providing data for model validation, the desired outcome of this testing was to demonstrate a negligible thermolytic HGR in Tank 22 from the contribution of glycolate from the future Defense Waste Processing Facility (DWPF) Nitric-Glycolic Acid (NGA) flowsheet to Tank 22. Tank 22 is the pathway for glycolate in the DWPF recycle stream to enter the CSTF. Testing with added glycolate used the estimated future concentration of glycolate based on DWPF recycle with limited Sludge Receipt and Adjustment Tank and Slurry Mix Evaporator (SME) material carry-over but without glycolate mitigation in the Recycle Collection Tank. Minor objectives include the determination of the impact of the glycolate source used in testing and the inclusion of sludge solids in testing.
