Unit 2 of the Shin Hanul nuclear plant was connected to South Korea’s grid

The 1.4 GW second unit of the Shin Hanul nuclear power plant, located in Uljin county, South Korea, has begun supplying its first electricity to the country’s power grid. The unit is the second of two APR-1400 reactors at the power plant operated by Korea Hydro & Nuclear Power (KHNP). 

Unit 2 reached its first criticality in early December 2023, and is set to begin full-scale commercial operation during the first half of 2024. Unit 1 entered commercial operations in December 2022, while two additional units for the plant are currently in the planning process. 

In 2022, nuclear represented 18% of South Korea’s installed capacity with nearly 25 GW and 28% of its power generation. In January 2023, South Korea’s Ministry of Industry, Trade and Energy unveiled a target to raise the share of nuclear power generation in the country to 32.4% by 2030 and 34.6% by 2036.
