EM Removes Tritium Facility at ORNL

EM crews have completed demolition on a contaminated 1960s-era building at the Oak Ridge National Laboratory (ORNL), opening land that DOE can reuse for future missions. With the Tritium Target Preparation Facility removed, crews can address the soils and substructures associated with the building. The cleanup effort eliminated several contaminated areas, allowing for a transformation in a location that can support the Department in the years ahead.

The History of ORNL’s Biology Complex at Y-12

Most of the buildings in what is known as the Biology Complex originally were constructed in 1945 as expansion capability for Y‑12’s uranium preparation operations. Before the scarce U‑235 isotopes could be separated from the abundant U‑238, the material had to be chemically processed and converted to the source material required for the calutrons, the machines created to do the separation. Being constructed late in the race to create the first atomic weapon, the buildings saw limited use and were shuttered quickly.
