Comprehensive Decommissioning International (CDI)

What Comprehensive Decommissioning International (CDI) does

Comprehensive Decommissioning International (CDI), also known as Holtec Decommissioning International (HDI), is a wholly-owned division of Holtec International that provides end-to-end nuclear power plant decommissioning, decontamination, and spent fuel management services to commercial utility operators and government-owned nuclear facilities. The division's service line covers site characterization, radiological cleanup, dismantling, demolition, civil construction, and land remediation, typically delivered through long-term, custom-priced project contracts with utility and government clients.

The underlying technology platform is built on Holtec's proprietary, NRC-qualified hardware portfolio, including the HI-STORE Consolidated Interim Storage Facility (CISF) for centralized spent fuel storage, and the dry cask and transport system family (HI-STAR, HI-STORM, HI-TRAC, HI-SAFE, Multi-Purpose Canisters). Supporting equipment covers wet fuel storage systems, heavy load handling (HI-TRAN, HI-LIFT), thermal management (HI-THERM HCSP, heat transfer equipment), and specialized tooling (HERMIT, VECASP, Forced Helium Dehydrator, Neutron Absorber Material). This integrated manufacturing-to-services stack allows CDI to internalize hardware supply within its decommissioning engagements.

CDI generates revenue primarily through professional services contracts for nuclear plant decommissioning projects, billed on a project-by-project, multi-year basis with pricing dependent on site-specific scope, regulatory requirements, and radioactivity profiles. The go-to-market is enterprise field sales targeting utility decision-makers, supplemented by industry conference participation and direct outreach. The division operates primarily in the United States, with international engagements across Canada, the UK, Ukraine, Brazil, Mexico, and Taiwan. CDI is currently anchored by the Palisades Nuclear Plant restart program and operates with approximately 47 employees as a division of Holtec International, which has filed for a proposed initial public offering.
