Wolsong 1, 2, 3, 4
Wolsong Units 1, 2, 3, 4
Republic of Korea
The Wolsong CANDU nuclear power plants are owned and operated by the Korea Hydro and Nuclear Power Company (KHNP). The four units at the Wolsong site are 700 MWe class CANDU 6 reactors, designed by AECL. Wolsong Unit 1 went into service in 1983 and Wolsong Units 2 and 3 began operation in 1997 and 1998. Wolsong Units 2, 3, and 4 repeat the basic design of Unit 1, with significant design updates and advancements.
Construction began at the Wolsong site in 1977 with the pouring of the reactor building sub-base for Unit 1, which had a 60-month construction period. Construction resumed at the site in 1992, on Wolsong Unit 2, and continued through Units 3 and 4—to October 1st, 1999, when Unit 4 was declared in-service. Several records were set during the work on Units 2, 3 and 4—the most notable being a 51-1/2 month construction duration for Unit 3 from first containment concrete to in-service.
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) automated wiring, which is a data management software tool, developed by AECL, for the design and installation of cabling and wiring.
