In support of decontamination and decommissioning (D and D) at the Portsmouth Gaseous Diffusion Plant (PORTS) and the current U.S. Department of Energy (DOE) mission of preparing areas for industrial reuse at PORTS, DOE plans to deactivate, demolish, and disposition two trailer complexes: the X-151 Contractor Office Trailer Complex and the X-152 Site Operations Management Complex. Numerous structures have been installed at PORTS since 2012 to support D and D of the former uranium enrichment facilities at the site, including these two trailer complexes. These trailer complexes include trailers, storage containers, chillers, generators, and associated utilities.
