The Wolseong Nuclear Power Plant, or Wolsong, [1] is a nuclear power plant located on the coast near Nae-ri, Yangnm-myeon, Gyeongju, North Gyeongsang province, South Korea. It is the only South Korean nuclear power plant operating CANDU-type PHWR (Pressurized Heavy Water Reactors). [2] Korea Hydro & Nuclear Power owns the plant. [3] These reactors are capable of consuming multiple types of fuel, including wastes from South Korea's other nuclear plants.
The power plant site including Yangnam-myeon. Yangbuk-myeon and Gampo-eup was designated an industrial infrastructure development zone in 1976. Construction of Wolseong 1 started in 1976 and was completed in 1982. In the following year, the power plant began commercial operations. This PHWR reactor has a gross generation capacity of 678 MW. Wolseong reactors 2, 3 and 4 were completed in 1997, 1998 and 1999, respectively. Each of these reactors has a capacity of 700 MW. Wolseong Nuclear Plant has since operated successfully. [2]
Wolseong Nuclear Power Plant supplies about 5% of South Korea's electricity. [4]
Shin-Wolsong No. 1 and No. 2, are two new OPR-1000 type pressurized water reactors. Shin-Wolsong 1 became fully operational in July 2012. [1] [5] [6]
In June 2013 Shin-Wolsong 1 was shutdown, and Shin-Wolsong 2 ordered to remain offline, until safety-related control cabling with forged safety certificates is replaced. [7] Shin Wolsong-1 was approved for restart in January 2014. [8] In November 2014, Shin Wolsong-2 loaded its first core of nuclear fuel, [8] and the plant was connected to the grid in February 2015, [9] with commercial operation commencing in July 2015. [10]

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.
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid, which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. As of 2022, the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world.
Bruce Nuclear Generating Station is a nuclear power station located on the eastern shore of Lake Huron in Ontario, Canada. It occupies 932 ha of land. The facility derives its name from Bruce Township, the local municipality when the plant was constructed, now Kincardine due to amalgamation. With eight CANDU pressurized heavy-water reactors, it was the world's largest fully operational nuclear generating station by total reactor count and the number of currently operational reactors until 2016, when it was exceeded in nameplate capacity by South Korea's Kori Nuclear Power Plant. The station is the largest employer in Bruce County, with over 4000 workers.
Kaiga Generating Station is a nuclear power generating station situated at Kaiga, near the river Kali, in Uttara Kannada district of Karnataka, India. The plant has been in operation since March 2000 and is operated by the Nuclear Power Corporation of India.
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.
Korea Hydro & Nuclear Power is a subsidiary of the Korea Electric Power Corporation (KEPCO). It operates large nuclear and hydroelectric plants in South Korea, which are responsible for about 27 percent of the country's electric power.
The Karachi Nuclear Power Plant is a large commercial nuclear power plant located at the Paradise Point in Karachi, Sindh, Pakistan.
Tarapur Atomic Power Station (T.A.P.S.) is located in Tarapur, Palghar, India. It was the first commercial nuclear power station built in India.
Nuclear power is a major power source in South Korea, providing 29% of the country's electricity. The total electrical generation capacity of the nuclear power plants of South Korea is 20.5 GWe from 23 reactors, equivalent to 22% of South Korea's total electrical generation capacity.
