The 1.4 GW second unit of the Shin Hanul nuclear power plant, located in the Uljin county of South Korea, has officially started operations. The unit is the second of two APR-1400 reactors at the power plant operated by Korea Hydro & Nuclear Power (KHNP), with two additional units being currently in the planning process. Shin Hanul 2 received an operating licence from the South Korean Nuclear Safety and Security Commission in September 2023, and after seven months of power increment and performance tests of the reactor and turbine generator, the unit started commercial operations on 5 April 2024.
In 2022, nuclear represented 18% of South Korea’s installed capacity with nearly 25 GW and 28% of its power generation. With the addition of the Shin-Haul Unit 2, South Korea counts with a total of 26 nuclear power plants (including the Kori Unit 2 which is currently preparing for its operating license renewal).
