The CANDU is a Canadian pressurized heavy-water reactor design used to generate electric power. The acronym refers to its deuterium oxide moderator and its use of uranium fuel. CANDU reactors were first developed in the late 1950s and 1960s by a partnership between Atomic Energy of Canada Limited (AECL), the Hydro-Electric Power Commission of Ontario, Canadian General Electric, and other companies.
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as Voyager 2. Generating electricity from fusion power remains the focus of international research.
Atomic Energy of Canada Limited (AECL) is a Canadian federal Crown corporation and Canada's largest nuclear science and technology laboratory. AECL developed the CANDU reactor technology starting in the 1950s, and in October 2011 licensed this technology to Candu Energy.
The Enrico Fermi Nuclear Generating Station is a nuclear power plant on the shore of Lake Erie near Monroe, in Frenchtown Charter Township, Michigan on approximately 1,000 acres (400 ha). All units of the plant are operated by the DTE Energy Electric Company and owned by parent company DTE Energy. It is approximately halfway between Detroit, Michigan, and Toledo, Ohio. It is also visible from parts of Amherstburg and Colchester, Ontario as well as on the shore of Lake Erie in Ottawa County, Ohio. Two units have been constructed on this site. The first unit's construction started on August 4, 1956 and reached initial criticality on August 23, 1963, and the second unit received its construction permit on September 26, 1972. It reached criticality on June 21, 1985 and was declared commercial on November 18, 1988. The plant is connected to two single-circuit 345 kV Transmission Lines and three 120 kV lines. They are operated and maintained by ITC Transmission.
The SLOWPOKE is a family of low-energy, tank-in-pool type nuclear research reactors designed by Atomic Energy of Canada Limited (AECL) beginning in the late 1960s. John W. Hilborn is the scientist most closely associated with their design. They are beryllium-reflected with a very low critical mass, but provide neutron fluxes higher than available from a small particle accelerator or other radioactive sources.
The anti-nuclear movement is a social movement that opposes various nuclear technologies. Some direct action groups, environmental movements, and professional organisations have identified themselves with the movement at the local, national, or international level. Major anti-nuclear groups include Campaign for Nuclear Disarmament, Friends of the Earth, Greenpeace, International Physicians for the Prevention of Nuclear War, Peace Action, Seneca Women's Encampment for a Future of Peace and Justice and the Nuclear Information and Resource Service. The initial objective of the movement was nuclear disarmament, though since the late 1960s opposition has included the use of nuclear power. Many anti-nuclear groups oppose both nuclear power and nuclear weapons. The formation of green parties in the 1970s and 1980s was often a direct result of anti-nuclear politics.
Nuclear power in Canada is provided by 19 commercial reactors with a net capacity of 13.5 gigawatt (GW), producing a total of 95.6 terawatt-hours (TWh) of electricity, which accounted for 16.6% of the country's total electric energy generation in 2015. All but one of these reactors are located in Ontario, where they produced 61% of the province's electricity in 2019. Seven smaller reactors are used for research and to produce radiopharmaceuticals for use in nuclear medicine.
Energy Alberta Corporation was created in 2005 with a concept to provide nuclear power to the energy-intensive development of the oil sands resources in northern Alberta, Canada. The company was founded by Hank Swartout, CEO of Precision Drilling Corporation, and Wayne Henuset, co-owner of Willow Park Wines and Spirits in Calgary, Alberta. The company intended to build a nuclear plant on the shore of Lac Cardinal, 30 kilometres (19 mi) from Peace River, Alberta.
Canada has access to all main sources of energy including oil and gas, coal, hydropower, biomass, solar, geothermal, wind, marine and nuclear. It is the world's second largest producer of uranium, third largest producer of hydro-electricity, fourth largest natural gas producer, and the fifth largest producer of crude oil. In 2006, only Russia, the People's Republic of China, the United States and Saudi Arabia produce more total energy than Canada.
The anti-nuclear movement in the United States consists of more than 80 anti-nuclear groups that oppose nuclear power, nuclear weapons, and/or uranium mining. These have included the Abalone Alliance, Clamshell Alliance, Committee for Nuclear Responsibility, Nevada Desert Experience, Nuclear Information and Resource Service, Physicians for Social Responsibility, Plowshares Movement, United Steelworkers of America (USWA) District 31, Women Strike for Peace, Nukewatch, and Women's International League for Peace and Freedom. Some fringe aspects of the anti-nuclear movement have delayed construction or halted commitments to build some new nuclear plants, and have pressured the Nuclear Regulatory Commission to enforce and strengthen the safety regulations for nuclear power plants. Most groups in the movement focus on nuclear weapons.
Nuclear power has various environmental impacts, both positive and negative, including the construction and operation of the plant, the nuclear fuel cycle, and the effects of nuclear accidents. Nuclear power plants do not burn fossil fuels and so do not directly emit carbon dioxide. The carbon dioxide emitted during mining, enrichment, fabrication and transport of fuel is small when compared with the carbon dioxide emitted by fossil fuels of similar energy yield, however, these plants still produce other environmentally damaging wastes. Nuclear energy and renewable energy have reduced environmental costs by decreasing CO2 emissions resulting from energy consumption.
The Pembina Institute is a Canadian think tank and registered charity focused on energy. Founded in 1985, the institute has offices in Calgary, Edmonton, Toronto, Ottawa, and Vancouver. The institute's mission is to "advance a prosperous clean energy future for Canada through credible policy solutions that support communities, the economy and a safe climate."
Nuclear weapons testing, uranium mining and export, and nuclear power have often been the subject of public debate in Australia, and the anti-nuclear movement in Australia has a long history. Its origins date back to the 1972–1973 debate over French nuclear testing in the Pacific and the 1976–1977 debate about uranium mining in Australia.
Anti-nuclear organizations may oppose uranium mining, nuclear power, and/or nuclear weapons. Anti-nuclear groups have undertaken public protests and acts of civil disobedience which have included occupations of nuclear plant sites. Some of the most influential groups in the anti-nuclear movement have had members who were elite scientists, including several Nobel Laureates and many nuclear physicists.
Nuclear power in Australia has been a topic of debate since the 1950s. Australia has one nuclear reactor in Lucas Heights, New South Wales, although it is only used to produce radioisotopes for nuclear medicine, and does not produce electricity. Australia hosts 33% of the world's proven uranium deposits, and is currently the world’s third largest producer of uranium after Kazakhstan and Canada.
