Summary
The Wolseong Nuclear Power Plant, or Wolsong,[1] is a nuclear power plant located on the coast near Nae-ri, Yangnam-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 Nuclear Power Plant edit
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]
