Bruce Power has leased eight Canadian-designed Candu reactors.
The four Bruce A reactors were not in operation when the plants were leased. However, Bruce Power has brought back into operation two of these reactors which together are capable of producing an additional 1,500 megawatts.
The six reactors can produce about 4,700 megawatts of clean electricity, enough to supply approximately 20% of Ontario's power needs.
The plants use about 1.5 million pounds U3O8 and 600 tonnes of uranium dioxide conversion services per year.
In Ontario, nuclear generated electricity is the cheapest after hydro.
