Clinton Engineer Works

In 1943, as part of the Manhattan Engineer District, the US. Government purchased 59,000 acres 12 miles west of Knoxville, Tennessee because it needed a remote location to build production plants and laboratories to produce plutonium and enriched uranium for the atomic bomb project. This facility was known as the Clinton Engineer Works (CEW) and was referred to generally as Oak Ridge. The entire CEW was bounded by security fences from February 1943 through March 1949. Within the CEW were the processing plants, known as Y-12, K-25 and X-10 (now ORNL) each of which had its own security fence (a fence within a fence) and has been designated separately for purposes of the EEOIPCA. During this time, Roane Anderson Company managed, operated and maintained residences, apartment, dormitories, guest houses, barracks, hutments, trailers, restaurants, cafeterias, buses, roads, streets, sidewalks, garbage and sewage disposal, heating plants and more for the CEW. Roane did not, however, operate the processing plants and laboratories. The CEW gates came down in March 1949. This meant that people no longer needed a security clearance to enter the CEW, though clearances were still required to enter the plants and laboratories. The fences surrounding the processing plants also remained. It was also in 1949 that the privatization of what is today known as the City of Oak Ridge began.
