Dew point, internal gas pressure, and chemical composition of the gas within the free volume of DWPF canistered waste forms

Type: conference-paper
Abstract: The Defense Waste Processing Facility (DWPF) produced 55 canistered waste forms containing simulated waste glass during the four Waste Qualification campaigns of the DWPF Startup Test Program. Testing of the gas within the free volume of these canisters for dew point, internal gas pressure, and chemical composition was performed as part of a continuing effort to demonstrate compliance with the Waste Acceptance Product Specifications. Results are presented for six glass-filled canisters. The dew points within the canisters met the acceptance criterion of < 20{degrees}C for all six canisters. Factors influencing the magnitude of the dew point are presented. The chemical composition of the free volume gas was indistinguishable from air for all six canisters. Hence, no foreign materials were present in the gas phase of these canisters. The internal gas pressures within the sealed canisters were < 1 atm at 25{degrees}C for all six canisters which readily met the acceptance criterion of an internal gas pressure of less than 1.5 atm at 25{degrees}C. These results provided the evidence required to demonstrate compliance with the Waste Acceptance Product Specifications.
