VIDEO: Hanford’s Foldtrack Installation in C-110

Submitted by on April 16, 2013 – 11:05 pmNo Comment


Crews successfully installed a new and improved version of the Foldtrack into tank C-110, a single-shell tank with about 17,200 gallons of waste remaining.

Workers lifted the Foldtrack and its 140-foot umbilical and remote umbilical interface unit into the air and installed it into a 12-inch riser. The device goes through the riser in the unfolded position and then is folded up prior to completely being set on the tank floor to become a robust waste-removal tool.

Installation required close communication between the control room and the field, including cooperation between Mission Support Alliance (MSA), construction and Washington River Protection Solutions (WRPS) retrieval crews. Operators in the control room ran cameras while MSA crane operators guided the Foldtrack into place.

Resembling a small bulldozer, the Foldtrack is a remotely operated, track-mounted system that uses a plow blade to move radioactive waste from the floor of an underground storage tank. In addition to the front-facing blade, the unit is also armed with two onboard water jet systems, three high-pressure turbo nozzles and a sluicing cannon for sweeping the tank floor.
