The DWPF must meet Waste Acceptance Preliminary Specifications (WAPS) for acceptance of the DWPF canistered waste forms. A number of these specifications deal with the exclusion of non-wasteglass (or foreign) materials within the canistered waste forms. Those material which are specifically excluded include the following: Free Liquids, Free Gases, other than cover or radiogenic gases, Explosives, Pyrophorics and Combustibles, and Organics. This report documents the results obtained by carrying out an assigned task as described in three task plans. The task plans cover the determination of pressure, gas composition and relative humidity of SRL canistered waste forms; and organic and inorganic analysis of volatilized and condensed species within SRL canistered waste forms. These results provide evidence to demonstrate compliance with these specifications and will be included in the Waste Form Qualification Report (WQR). In all, four canistered waste forms, produced during the Scale Glass Melter (SGM) campaigns, were examined. The internal gas pressure, dewpoint temperature and gas composition were determined for each canistered waste form. The experience gained in these experiments will be used to generate procedures for obtaining the same information on canistered waste forms produced during the Integrated Cold Runs (ICR). 10 refs., 2 figs., 1 tab. |
