|Bruce A Restart and Refurbishment Project (3,000 MW) - Tiverton|
Power is generated at a nuclear generation station by producing steam to turn steam turbines by a controlled nuclear fission reaction. The reaction takes place inside a reactor, which consists of a fuel (fissionable material), moderating material to control the reaction rate, a heavy-walled pressure vessel to house reactor components, shielding to protect personnel, a cooling system and instrumentation for monitoring and controlling the reactor’s systems.
Currently, all nuclear reactors in Canada use the CANDU design. CANDU stands for “CANada Deuterium Uranium” and was developed between the 1950’s and 1960’s by a partnership between Atomic Energy of Canada Limited (AECL), the Hydro-Electric Power Commission of Ontario (now Ontario Power Generation), Canadian General Electric (now GE Canada) and several private industry participants. CANDU is a type of pressurized heavy water reactor that uses deuterium-oxide (heavy water D2O) as a moderator and natural uranium fuel.
Heat is generated by a controlled fission reaction in the heavy water which is pressurized to raise its boiling point. The hot heavy water passes through a heat exchanger, heating ordinary water and creating steam. The steam turns a turbine, which also turns a generator to produce electricity.

Nuclear Power Contract
The Bruce Nuclear facility, located on Lake Huron in Tiverton, Ontario, is the largest nuclear facility in North America in terms of output with a total output capacity of 6,224 MW (net) and 6,610 MW (gross). It houses two nuclear generating stations – Bruce A and Bruce B – and each generating station has four CANDU reactors.
