CANadian Deuterium Uranium

A proven pressurized heavy-water reactor design, refined over decades.

Natural uranium fuel

Unlike light-water reactors, CANDU uses unenriched natural uranium — eliminating the need for costly enrichment facilities.

Deuterium oxide serves as both moderator and coolant, sustaining highly efficient nuclear reactions.

Robotic refueling machines swap fuel bundles at full power, preventing refueling shutdowns and enabling long continuous runs.

Runs on alternative fuels including recovered uranium, mixed-oxide (MOX) fuel and thorium.
