The Hanul nuclear site, formerly Ulchin, has eight operating reactors, Hanul 1 to 6 and Shin Hanul 1 and 2. Shin Hanul units 3 and 4 are expected to be completed by 2033 and add a further 2.68 GW of capacity. Construction on these units began in 2024.
The site is located on the east coast of South Korea and uses water from the Sea of Japan for cooling. Construction of Hanul 1 began in 1983 and it began operation in 1988. Shin Hanul 2, the newest operational reactor, began construction in 2013 and became operational in 2023 after its 241 fuel assemblies were loaded.
Hanul units 1 and 2 use France CPI reactors and units 3 through 6 use OPR- 1000 reactors. Both of the operational Shin Hanul units use APR-1400 reactors.
In 2024, roughly 10 % of the country’ s electricity generation came from the Hanul nuclear plant, around 61,985 GWh.
