Bruce Nuclear Power Plant, Canada

The Bruce nuclear power plant is located in Tiverton, province of Ontario, in Canada. The facility is located in the geographical area of ​​Bruce County, hence its name. It occupies an area of ​​932 hectares.

The nuclear power plant was built in stages between 1970-1987 by the provincial crown corporation, Ontario Hydro. It was not until May 2001 that the Bruce nuclear power plant began operating. Currently, 3,800 employees work at the headquarters.

The initial operating license is 18 years, it would expire in 2019, but there is an option to extend it up to 25 more years until 2044.

The Bruce Nuclear Power Plant is Canada's highest power output plant. Its total power capacity of 6,272 MW (net) and 7,276 MW (gross).

In November 2009 the Canadian Nuclear Safety Commission (CNSC) renewed the operating licenses of the Bruce plant for 5 more years, until 2014. In May 2014 the license was renewed until May 2015. Later a new license until May 2020.

What Kind of Nuclear Reactor Does the Bruce Nuclear Power Plant Have?

The facility is made up of 8 CANDU-type nuclear reactors, which makes it the world's nuclear power plant with the largest number of reactors. The Kashiwazaki-Kariwa nuclear power plant in Japan is larger than Bruce's, but is not currently in operation.

CANDU reactors are a type of reactors developed in Canada. It is a type of pressurized heavy water reactor.

Layout of the Reactors at the Bruce Nuclear Power Plant

The 8 nuclear reactors at the Bruce plant are divided into two plants (Plant A and Plant B). Each of the plants has 4 reactors. Each nuclear reactor is housed in a reinforced concrete containment structure with eight massive steam generators of 100 tons each.

Each reactor has its own set of turbines: a high-pressure turbine and three low-pressure turbines that drive the electric power generator.

Water from Lake Huron is used for the cooling system.

Each unit has its own control room for the 4 nuclear reactors each has.

Nuclear Incidents at the Bruce Nuclear Power Plant

In 1990, an emergency situation occurred in the fourth power unit of the Bruce Nuclear Power Plant. As a result, there was a leak of heavy water from the primary circuit of the reactor.

The reactor was shut down and cooled in a standard emergency system. Most of the water was contained, however the unit was taken out of production for 12 weeks. It was recognized that a flaw in computer software was the cause of the nuclear accident.
