Sludge Removed From WCF Underground Storage Tanks


The Waste Concentration Facility (WCF), Building 811, was used to store and distill liquid radioactive waste from several Laboratory facilities. The WCF consists of numerous above- and below-ground storage tanks. Three above-ground 100,000-gallon D-waste tanks were removed in 1995. Six 8,000-gallon underground stainless steel tanks are scheduled for removal.

In the fall of 1999, 70 cubic yards of contaminated sludge (over 14,000 gallons) was removed from the six USTs. The sludge was solidified and packaged, and was shipped off-site for disposal.
