ConverDyn
ConverDyn is a USA company active in the nuclear fuel chain as converter.
Marketing agent for the Metropolis Works conversion plant in Illinois, the only uranium conversion facility in the United States. Metropolis was idled in 2017 when conversion prices collapsed and restarted in 2023 as the market tightened, a single plant whose on/off decision moves the entire Western conversion balance.

ConverDyn in context

ConverDyn has 1 facility on record in 1 country (United States): 1 operating.
Share of each stage it works in
| Stage | Company | World total | Share | Rank | Source |
|---|---|---|---|---|---|
| Conversion | 7,000tU/yr as UF6 | 62,000(2022) | 11% | 5 of 5 | World Nuclear Association, Conversion and Deconversion |
How these are worked out: shares and ranks use the world totals cited in the table, and only named companies are ranked (unnamed or country-level entries in a source are not). A facility with no stated capacity is counted as a facility but adds nothing to a capacity figure. Vendor figures count operating units where this company is the recorded reactor vendor; ages count from the start-up year on record, and build times run from construction start to grid connection, as on the age and build-times pages.
