Comprehensive Decommissioning International (CDI) is safely decommissioning the following nuclear plants:

Oyster Creek Decommissioning Site

Located on New Jersey’s picturesque Barnegat Bay, Oyster Creek permanently shut down in September 2018 and entered into immediate decommissioning.

Pilgrim Decommissioning Site

Located in historic Plymouth, Massachusetts, Pilgrim permanently shut down in May 2019 and entered into immediate decommissioning.


CDI is backed by decades of experience through its corporate parents, Holtec International and SNC-Lavalin. 

Holtec International has provided safe, robust and reliable solutions for managing the backend of the nuclear power cycle for commercial nuclear power plants, since 1986. As a world leader in spent nuclear fuel storage technology design and implementation, Holtec’s wet and dry storage and transport systems provide confinement, radiation shielding, structural integrity, criticality control and heat removal for used nuclear fuel. Over 115 nuclear plants rely on Holtec’s dry storage technology for their storage and transportation needs.

SNC-Lavalin (SNCL) brings significant U.S. decommissioning expertise in both commercial and government markets. This expertise includes the baseline planning, license transfer, project delivery through fuel transfer, and reactor segmentation at the Zion station. This team also managed the United Kingdom’s fleet of 22 Magnox reactors through operation and into decommissioning. More recently, SNCL has enjoyed success safely progressing cleanup efforts at Fukushima Dai-ichi in Japan, the Ringhals Units 1&2 in Sweden and the Nuclear Power Demonstration (NPD) reactor in Canada.
