Hanford Uses New, Enhanced Methods to Remove Pumps From Waste Tanks

RICHLAND, Wash. - After practicing in a nonradioactive environment this spring, workers at the Hanford Site recently used a robotic arm to help remove an old 34-foot pump from a large underground tank, called AP-102, that stores radiological and chemical waste. Workers also used a system that encapsulated the pump in a shielding bag as it was removed from the tank, protecting workers from contaminants. U.S. Department of Energy Office of Environmental Management contractor Washington River Protection Solutions regularly removes and replaces aging equipment, but the long pump had small spaces that could trap radiological and chemical tank waste, which required the use of the shielding bag. The tank infrastructure is being upgraded to support the Direct-Feed Low-Activity Waste Program to immobilize tank waste in glass.
