The 1.6 km-long building known as K25 took five years to demolish. Courtesy US DOE. A decades-long effort to clean and transform the former Oak Ridge Gaseous Diffusion Plant in the US state of Tennessee is complete, resulting in the first-ever removal and remediation of a uranium enrichment complex.

Since cleanup operations began, hundreds of buildings measuring more have been demolished and more than 1.2 million cubic metres of waste –enough to fill up more than 500 Olympic-size swimming pools – have been disposed, including nearly 30,000 truckloads of soil.

This progress has paved the way for the US Department of Energy’s Office of Environmental Management to transfer more than 500 hectares of land  at the facility, also known as the East Tennessee Technology Park, back to the community for economic development with another 40 hectares set aside for historic preservation.

In the 1940s, the Oak Ridge site produced enriched uranium to power the atomic weaponry that ended World War II.

US Centrus Energy Corp (formerly known as USEC) announced on 2 October that it had been awarded a $15 million work authorisation by the US Department of Energy (DOE) for decontamination and decommissioning (D&D) to prepare the K-1600 facility in Oak Ridge, Tennessee, for demolition. Centrus has leased K-1600 - the former K-25 site -  from the DOE since 2002 to test and demonstrate its uranium enrichment technology. The company has also been conducting centrifuge manufacturing, engineering and design at its own nearby Technology and Manufacturing Centre (TMC) in south Oak Ridge, at the former Boeing plant.
