Decontamination and Decommissioning (D&D)

Shaw offers extensive maintenance and modification experience directly relating to nuclear plant decommissioning. We have provided decontamination and decommissioning services at eight commercial nuclear reactors, seven research reactors and one U.S. Army reactor, as well as nuclear facility decommissioning services at 10 government facilities.

Shaw performed engineering, design and construction for the decommissioning of Maine Yankee, the first competitive commercial nuclear plant decontamination and decommissioning contract. We worked with the American Society of Mechanical Engineers to develop and deploy a first-of-its-kind N-stamp spent fuel canister and achieved U.S. Nuclear Regulatory Commission license termination and unrestricted release of the site.

Shaw has more than 30 years of technical knowledge and experience from lessons learned in the decontamination and decommissioning of radiological hot cells, laboratories, research and commercial power reactors, and other nuclear facilities. We understand the complex challenges managers and contractors face as they plan the decontamination and decommissioning of nuclear facilities, including co-location with other operations, proximity to areas with heavily used public access, unusual isotopes and significant isotopes.
