摘要

Mixed low-level waste (MLLW) contains both low-level radioactive materials and low-level hazardous chemicals. The hazardous component of mixed waste has characteristics identified by any or all of the following statutes: the Resource Conservation and Recovery Act of 1976 (RCRA), as amended; the Toxic Substances Control Act of 1976; and Washington State dangerous waste regulations. The Fluor Hanford Waste Management Project (WMP) is responsible for storing, treating, and disposing of solid MLLW, which includes organic and inorganic solids, organics and inorganic lab packs, debris, lead, mercury, long-length equipment, spent melters, and remote-handled (RH) and oversized MLLW. Hanford has 7,000 cubic meters, or about 25%, of the MLLW in storage at U.S. Department of Energy (DOE) sites. Hanford plans to receive 57,000 cubic meters from on-site generators, or about 50% of DOE’s newly generated MLLW. In addition, the Hanford Environment Restoration Program and off-site generators having approved Federal Facility Consent Agreement site treatment plans will most likely send 200 cubic meters of waste to be treated and returned to the generators. Volumes of off-site waste receipts will be affected when the MLLW Record of Decision is issued as part of the process for the Hanford Site Solid Waste Environmental Impact Statement (EIS). The WMP objective relative to MLLW is to treat and dispose of ~8000 cubic meters of existing inventory and newly-generated waste by September 30, 2006. Current and future activities in support of this objective include the following: ? A heat exchanger/condenser unit was managed as mixed waste and shipped to Duratek’s Bear Creek facility where it was melted down and recycled to form steel shield blocks ?saving disposal costs and disposal trench space. ? Fluor Hanford and the DOE have petitioned the U. S. Environmental Protection Agency (EPA) for a RCRA exclusion (“delisting”) to allow disposal of MLLW with U and P listed waste codes and subsequent treatment of leachate from the disposal trench. ? Fluor Hanford’s WMP is in the process of demonstrating thermal desorption as an alternative method of thermal treatment.
