The longest of the radioactive waste storage tunnels at the Hanford nuclear reservation’s PUREX plant was built in the shape of a Quonset hut, with steel ribs supporting corrugated steel plate roof panels. Improvements were made it its design after it collapsed twice during construction.

  • Workers take down Plutonium Reclamation Facility Canyon

    This video from November shows demolition of the north wall of the canyon, allowing heavy equipment to begin removing strong backs from the walls. Strong backs are brackets from which pencil-shaped processing tanks once hung. It also shows the array of dust suppression tools, each spraying water from a different angle to help control radiological contamination during demolition.
