CH2M Hill Announces a Fourth Hanford Tank Emptied

HANFORD - One of the Hanford Site's older, single shell nuclear waste storage tanks is now empty, thanks to unique, new technology.

Tank C-201 was used between 1947 and 1956. Vacuum retrieval technology developed by CH2M Hill for use at Hanford was used to retrieve the 860 gallons of solid waste left in the tank. Liquids were removed from the tank in 1981, but solid material remained behind.

CH2M Hill leaders say the cleanout of this tank represents real progress toward their goal of removing waste from the single shell tanks and moving it to safer, double shell tanks where it'll be stored until it's prepared for disposal.

Waste retrieval is also underway on three additional single shell tanks at Hanford.
