Available in PDF, EPUB and Kindle. Book excerpt: The Integrated DWPF Melter System (IDMS) for the vitrification of high-level radioactive wastes is designed and constructed to be a 1/9th scale prototype of the full scale Defense Waste Processing Facility (DWPF) melter. The IDMS facility is the first engineering scale melter system capable of processing mercury, and flowsheet levels of halides and noble metals. In order to determine the effects of mercury on the feed preparation process, the off-gas chemistry, glass melting behavior, and glass durability, a three-run mercury (Hg) campaign was conducted. The glasses produced during the Hg campaign were composed of Batch 1 sludge, simulated precipitate hydrolysis aqueous product (PHA) from the Precipitate Hydrolysis Experimental Facility (PHEF), and Frit 202. The glasses were produced using the DWPF process/product models for glass durability, viscosity, and liquidus. The durability model indicated that the glasses would all be more durable than the glass qualified in the DWPF Environmental Assessment (EA). The glass quality was verified by performing the Product Consistency Test (PCT) which was designed for glass durability testing in the DWPF.

Book Synopsis Durability of Glasses Vitrified from High Copper Feed in the 774 Research Melter by :

Available in PDF, EPUB and Kindle. Book excerpt: Small scale crucible studies were performed by Schumacher to examine the effects of formate and nitrate on glass redox at high copper levels. The results of the crucible studies were used to determine the regions where copper precipitates in the glass. However, durability tests were not performed on the glass samples. Studies were performed in the 774 Research Melter using a simulated feed from the Purex 4 Campaign in the Integrated DWPF Melter System (IDMS). Three runs were performed with this simulated feed. The first used the feed as it was received to determine a baseline. The results from the second and third campaigns were compared to the baseline. The second run increased the copper concentration. The third increased the copper and formate concentrations. The purpose of these experiments was to investigate melter performance and glass durability using a feed with increased copper concentration. The Purex 4 feed did not contain the target amounts of sludge and Precipitate Hydrolysis Aqueous (PHA). Less than 20% of the feed slurry consisted of simulated sludge, making it a low waste-loading feed. The use of this feed with significantly more copper added than anticipated in the DWPF, showed no indication of copper precipitating in the melter. In addition, the glasses produced during the campaigns were more durable than the benchmark glass.

Available in PDF, EPUB and Kindle. Book excerpt: Glass produced during the Purex 4 campaigns of the Integrated DWPF Melter System (IDMS) and the 774 Research Melter contained a lower fraction of sludge components than targeted by the Product Composition Control System (PCCS). Purex 4 glass was more durable than the benchmark (EA) glass, but was less durable than most other simulated SRS high-level waste glasses. Further, the measured durability of Purex 4 glass was not as well correlated with the durability predicted from the DWPF process control algorithm, probably because the algorithm was developed to predict the durability of SRS high-level waste glasses with higher sludge content than Purex 4. A melter run, designated Purex 4 Remediation, was performed using the 774 Research Melter to determine if the initial PCCS target composition determined for Purex 4 would produce acceptable glass whose durability could be accurately modeled by the DWPF glass durability algorithm. Reagent grade oxides and carbonates were added to Purex 4 melter feed stock to simulate a higher sludge loading. Each canister of glass produced was sampled and the glass durability was determined by the Product Consistency Test method. This document details the durability data and subsequent analysis.
