Facility

Cameco Port Hope Conversion Facility

Converts uranium concentrates (U3O8) to uranium hexafluoride (UF6) for enrichment and to uranium dioxide (UO2) for CANDU fuel. One of only 4 commercial conversion facilities in the world (alongside Honeywell Metropolis Works/US, Orano Comurhex/France, and ConverDyn's mothballed US facility). Port Hope resumed full operations in 2023 after a major refurbishment. Conversion is a lesser-known chokepoint — uranium must be converted before enrichment.
