In 2002, the Uranium Disposition Services (UDS) Company was awarded a Department of Energy (DOE) contract to design, construct, and operate two depleted uranium hexaflouride conversion facilities at Paducah , KY and Portsmouth , OH . Groundbreaking for the two facilities was held in July, 2004. Construction began immediately after groundbreaking. The construction efforts were limited to site preparation, underground utilities, storm water systems, site fencing and lighting and foundation work for the Administration and Warehouse buildings.

On September 30, 2005 final design was approved by the DOE and authorization to proceed with full construction was granted.

This page will provide a pictorial history of construction progress of these facilities.
