Glass-filled canisters, produced at the SRS Defense Waste Processing facility, must meet the Waste Acceptance Preliminary Specifications (WAPS) developed by DOE's Office of Civilian Radioactive Waste Management. Certain of these specifications relate to the exclusion of foreign materials from the canister. As part of an overall program to show compliance with these specifications, experiments were performed which characterized the free volume of the canistered waste forms. Measurements of the dew point, internal gas pressure and gas composition were made on four canisters which had been filled with simulated waste glass at SRS's large scale pilot plant, and then sealed. These results demonstrate DWPF's ability to comply with the WAPS.
