The South Korean nuclear power plant Wolsong consists of six blocks. The location is in Gyeongsangbuk-do Province . The owner and operator is the Korea Hydro and Nuclear Power Corporation (KHNP). Directly next to the four Wolsong reactor blocks are two further reactor blocks, which are referred to as Shin-Wolsong ( "New Wolsong" ).

Wolsong

Units 1-4 are CANDU reactors (Type 6) and were supplied by Atomic Energy of Canada Limited (AECL).

Wolsong 1 generated 683 MW. The system became critical for the first time on November 21, 1982 and went online for the first time on December 31, 1983. The second block Wolsong 2 has an output of 635 MW. Construction began in 1991, the reactor went critical on January 29, 1997 and was connected to the public grid on April 1, 1997. Wolsong 3 went critical on February 19, 1998 and went online on March 25, 1998. Wolsong 4 went critical on April 10, 1999 and went online on May 21, 1999.

On June 20, 2018, Wolsong 1 was the second reactor block in South Korea to be shut down; the plant had been subcritical since May 2017. The operating license would have allowed a term until 2022, but decommissioning was brought forward.

Accidents

  • On October 20, 1994, after a valve broke, heavy water leaked from the Wolseong 1 reactor for two hours . It was the same spot that the valve at Pickering Nuclear Power Plant broke in December 1994 . The incident was rated 2 on the INES scale .
  • On October 4, 1999, 22 workers were contaminated when 45 liters of heavy water leaked from the Wolseong 3 reactor.

Shin-Wolsong

Shin-Wolsong units 1 and 2 are light water moderated pressurized water reactors with a nominal electrical output of 1045  MW and 1050 MW.

Construction of the Shin-Wolsong-1 reactor began on November 20, 2007; it was first synchronized with the power grid on January 27, 2012. The block went into commercial operation on July 31, 2012.

Construction of the Shin-Wolsong-2 reactor began on September 23, 2008; it was synchronized with the power grid for the first time on February 26, 2015. The block went into commercial operation on July 24, 2015.
