242-A Evaporator Operating Unit Group 4 (OUG-4)
[TSD ID#: T-2-6] Located in Hanford’s 200 East Area, it began operating in 1977. This unit accepts waste from the double-shell tanks and boils it to extract water and concentrate the waste, which goes back to the double-shell tanks. This creates more space in the double-shell tanks so waste can be transferred from the older, noncompliant single-shell tanks. Each evaporator campaign makes about 500,000 gallons of tank space available. The condensate goes to LERF-ETF for treatment.
