Argentina, Romania, South Korea and China

Argentina

In 1975, Canada and its CANDU reactor continued their foray into the world nuclear reactor market when construction began on the Embalse CANDU generating station, in Cordoba, Argentina. Owned and operated by Nucleoeléctrica Argentina Sociedad Anónima (NASA), the Embalse plant began commercial operation in January 1984. As well as supplying Argentina with electricity, Embalse is also used to produce cobalt-60, a radioisotope that is used in medical and industrial applications As a result, Argentineans can rely on a local supply of radioisotopes rather than depending on those from foreign markets.

South Korea

In 1976, construction began on the Wolsong Generating Station in South Korea, Canada’s first third-generation reactor export to Asia. Since then, South Korea has added three more CANDU units to its Wolsong facility. The CANDU nuclear power plants are owned and operated by the Korean Electrical Power Company. Units 2, 3 and 4 were designed and constructed using state-of-the-art integrated electronic engineering tools including Computer Aided Design and Drafting (CADD) systems and Integrated Electrical Control (IntEC), a software tool developed by Atomic Energy of Canada Limited to aid in the design and installation of cable and wiring.

Romania

The Cernavoda Unit 1 nuclear power plant located in Romania was the first CANDU in Europe, coming online in 1997. It provides about 9% of Romania’s electricity requirements, saving millions of dollars in oil imports each year. The owner and operator is the Romanian nuclear state utility, Societatea Nationala Nuclearelectrica. Atomic Energy of Canada Limited also transferred its CANDU fuel and heavy water technology to Romania so it could locally manufacture fuel bundles and heavy water for the moderator and coolant. A second CANDU nuclear power plant, Cernavoda Unit 2, began producing power in 2007.

China

The Qinshan Phase III CANDU project is located in Haiyan County, Zhejiang Province, China. It is owned and operated by the Third Nuclear Power Company Ltd. and has two 700 MW CANDU reactors. Qinshan 4 came into service in 2002 and Qinshan 5 came into service in 2003. It was also constructed with state-of-the-art engineering and information tools, including comprehensive 3-D Computer Aided Design and Drafting (CADD) systems that allowed the builders to visualize and animate construction sequences to develop the optimum schedule before construction began. The use of CADD and other software helped complete Qinshan Phase III under budget and ahead of schedule.

All CANDU reactors built outside Canada, except for the early units in India and Pakistan, are of the CANDU 6 design. Each 700 MW CANDU 6 unit has avoided the release of approximately five million tonnes per year of greenhouse gases (carbon dioxide), equivalent to the greenhouse gases produced by about one million cars.
