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.
