Nuclear facility – Port Hope Conversion Facility

The Port Hope Conversion Facility processes uranium trioxide (UO3) from the Blind River Refinery into both uranium dioxide (UO2) and uranium hexafluoride (UF6). The UO2 is used to manufacture fuel for CANDU heavy water nuclear reactors in Canada, while the UF6 is exported to companies around the world for enrichment and fabrication into fuel for light water nuclear reactors.
