LLNL has a demonstration plant working on non-radionuclide contaminated waste materials like rubber. A tour of the processing experimental area in the Plutonium Facility included observation of much of the apparatus for the above processes. However, progress has been slow and is about to stop for lack of funding. The plan is to screen out most of the alternatives by September 1994, concentrating on the remaining two or three most promising concepts. The final choice will be made by September 1995.
Vitrification is the leading candidate, according to the project leader.
LLNL is scheduled to do a number of technical and economic assessments as paper studies. Only very limited funds are available for experimental or testing work. A more recent radiographic examination of 15 cans found two with inner bulging cans. It was reported to have been heat treated to 650 C, but not stabilized. Apparently this treatment was not sufficient to prevent subsequent radiolytic reactions, and the contents pressurized its sealed container.
