1. Washington Closure Hanford, Richland, Washington (United States)

In 2005, the U.S. Department of Energy (DOE) launched the third generation of closure contracts, including the River Corridor Closure (RCC) Contract at the Hanford Site, which was awarded to Washington Closure Hanford (WCH). One portion of the WCH company structure is known as the D4 project, where D4 represents the deactivation, decommissioning, decontamination, and demolition of excess facilities. The RCC Contract scope requires that approximately 485 excess facilities undergo the D4 process. During 2005 and 2006, significant acceleration has been achieved in completing the D4 of these facilities. By the end of November 2006, more than 70 facilities had been completed, while only 22 were scheduled for completion. This acceleration has been achieved by implementing innovative work practices and refinement of techniques developed at other DOE such as Rocky Flats, Mound, and Savannah River. In addition, a number of unique equipment deployments have supported the acceleration. While the RCC Project is moving along an accelerated path, there are a number of challenges ahead. The challenges discussed in this paper relate to project impacts that could result from the delayed release of excess facilities in the 300 and 100-K Areas and the potential for mitigation of these impacts.
