Candu Reactor Fuel Bundle

This CANDU fuel bundle commemorates a milestone in Canada’s nuclear-power industry: produced in 1975, it is the 100,000th bundle made in Canada. CANDU is a nuclear-powered electricity generation system developed in Canada after the Second World War. Standing for CANada Deuterium Uranium, CANDU reactors use deuterium oxide — heavy water — to moderate the high-energy nuclear reactions produced by fission within these uranium fuel rods. The heat generated by these reactions produces high-pressure steam, which then drives turbines that generate electricity. CANDU reactors are in use around the world.

The first CANDU-type reactor came into use in Rolphton, Ontario, in 1962.
