Wolseong Nuclear Power Plant (Korean: 월성원자력발전소 ), also known as Wolsong Nuclear Power Plant. It is located in the east of South Korea near the Sea of Japan. It is built at Nae-ri, Yangnm-myeon, Gyeongju, North Gyeongsang province.
Wolseong Nuclear Power Plant will be constructed in two phases, with a total of 6 reactors and an installed capacity of 3,835 MW.
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.
Wolseong Nuclear Power Plant supplies about 5% of South Korea’s electricity. It is the only South Korean nuclear power plant operating CANDU-type PHWR (Pressurized Heavy Water Reactors).
Korea Hydro & Nuclear Power owns the plant. These reactors are capable of consuming multiple types of fuel, including wastes from South Korea’s other nuclear plants.
Shin-Wolsong Nuclear Power Plant
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.
In November 2014, Shin Wolsong-2 loaded its first core of nuclear fuel, and the plant was connected to the grid in February 2015, with commercial operation commencing in July 2015.
