The United States Department of Energy (DOE) contracted with British Nuclear Fuels Ltd (BNFL) in 1997 to decontaminate and decommission the facilities. Its subsidiary Reactor Sites Management Company Limited (RSMC) was acquired by EnergySolutions in June 2007. Initially K-29, K-31 and K-33 were to be retained for other uses, but it was subsequently decided to demolish them. Bechtel Jacobs, the environmental management contractor, assumed responsibility for the facility in July 2005. Demolition of K-29 began in January 2006, and was completed in August. Demolition of K-33 began in January 2011, and was completed ahead of schedule in September 2011. It was followed by the demolition of K-31, which began on 8October 2014, and was completed on 26 June 2015.
