Decontamination and Decommissioning (D&D)

Shaw also offers extensive maintenance and modification experience directly relating to nuclear plant decommissioning. We support 116 of 119 commercial plants in the United States with a variety of construction, engineering and quality assurance tasks. We have provided D&D services at eight commercial nuclear reactors, seven research reactors, and one U.S. Army reactor, as well as nuclear facility decommissioning services at ten government facilities.

Shaw performed engineering, design, and construction for the decommissioning of Maine Yankee, the first competitive commercial nuclear plant D&D contract. Shaw worked with ASME to develop and deploy a first-of-its-kind N-stamp spent fuel canister and achieved Nuclear Regulatory Commission license termination and unrestricted release of the site.

With more than 30 years of technical knowledge and experience from lessons learned in the D&D 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 D&D of nuclear facilities-co-location with other operations, proximity to areas with heavily used public access, unusual isotopes, and significant isotopes.
