Client: US Department of Energy National Energy
Technology Center
Waste Treated: Asbestos
Project Initiated: October, 2000
Project Completed: May, 2002
Project Goal: Deploy technology for asbestos destruction
& evaluate suitability for RAD immobilization
The
current inventory of radioactive asbestos in the DOE complex
is estimated to be 4,000,000 lb. Thus, the DOE has an interest
in technologies that have the ability to destroy the asbestos,
immobilize the radionuclides, and reduce the volume of the
waste. The US Department of Energy National Energy Technology
Center in Morgantown, West Virginia awarded ARI a contract
to deploy its technology and demonstrate the effectiveness
of the technology in destroying asbestos from DOE facilities.
Ten thousand pounds of asbestos originating from an abatement
project at the DOE Savannah River Complex was transported
to ARIs test facility in Tacoma, Washington. ARI conducted
tests on the asbestos in early 2002.
The
project was successful in destroying the asbestos and reducing
the volume of the waste by over 60%. Portions of the asbestos
were spiked with Lead, Barium, Cadmium, Arsenic, Cesium
and Cerium to demonstrate the ability of the process to
immobilize toxic metals and surrogate radionuclides. TCLP
tests showed that leach performance for the RCRA metals
surpassed EPA performance standards by no less than an order
of magnitude. Product Consistency Testing (PCT) showed that
the chemical durability of the product was equivalent or
better than vitrified radioactive waste with similar chemistry.
