Comprehensive Decommissioning International, LLC (CDI) was formed in 2018 with the express purpose of creating a company to provide all-encompassing project solutions for the accelerated decommissioning of retired nuclear power plants. CDI, based in Camden, NJ, draws on its partners’ financial strength, safety commitment and 60 years’ experience, and expertise in decommissioning and site remediation to carry out decommissioning, which could benefit the local communities by returning these plant sites (excluding the Independent Spent Fuel Storage Installations) to productive use sooner. The used fuel will remain under guard at the sites and will be monitored during shutdown and decommissioning, subject to the NRC’s oversight, until the US Department of Energy removes it, in accordance with its legal obligations. By leveraging strong financial histories, technical and project management capabilities, depth in life-cycle fuel experience, and innovation through first-to-market technologies, CDI has positioned itself as a solution provider and leader in this exciting and growing market.

In line with the core values of its parent companies, CDI is committed to enriching the communities in which we operate. We recognize the trust that communities place in us to return current plants to a safe and reusable status for future generations, an obligation we do not take lightly. CDI intends to integrate with communities by communicating through public outreach platforms, hiring locally and contributing civically in a meaningful way. By employing financially sustainable business practices, we will ensure the upholding of obligations made as a trusted steward of legacy nuclear materials. Our goal is to ensure the safe and quality decommissioning of nuclear sites in a prompt fashion that enables sites for reuse more quickly than our competitors, or by utilities themselves.

About Our Parent Organizations

Holtec International is a privately held energy technology company with operation centers in Florida, New Jersey, Ohio and Pennsylvania in the US, and globally in Brazil, Dubai, India, South Africa, Spain, UK and Ukraine. Holtec’s principal business concentration is in the nuclear power industry. Holtec has played a preeminent role since the 1980s by densifying wet storage in nuclear plants’ spent fuel pools deferring the need for and expense of alternative measures by as much as two decades at over 110 reactor units in the US and abroad. Dry storage and transport of nuclear fuel is another area in which Holtec is recognized as the foremost innovator and industry leader with a dominant market share and an active market presence in eighteen countries. Among the Company’s pioneering endeavors are the world’s first below-ground Consolidated Interim Storage Facility being developed in New Mexico and a 160-Megawatt walk away safe small modular reactor, SMR-160. The SMR-160 is developed to bring cost competitive carbon-free energy to all corners of the earth including water-challenged regions. Holtec is also a major supplier of special-purpose pressure vessels and critical-service heat exchange equipment such as air-cooled condensers, steam generators, feedwater heaters, and water-cooled condensers.  Virtually all products produced by the Company are built in its three large manufacturing plants in the US and one in India. Thanks to a solid record of consistent profitability and steady growth since its founding in 1986, Holtec has no history of any long-term debt and enjoys a platinum credit rating from the financial markets. Nearly 100 US and international patents protect the Company’s intellectual property from predation by its global competitors and lend predictable stability to its business base.
