The South Korean government has approved a plan to increase the share of nuclear in the country's power mix to 30% or more by 2030 (from 27% in 2021), and to resume stalled construction work on two 1.3 GW reactors (Shin Hanul 3 and 4). In addition, the country suspended a gradual nuclear phase-out with the closure of 10 of its 28 nuclear reactors by 2038 initiated in 2017 by the previous administration. In May 2022, the country put Unit 1 of the Shin Hanul nuclear plant online (1.3 GW).
The new government plans to set new targets for solar and wind power with the objective to cut the country's reliance on fossil fuel imports to around 60% by 2030. In 2021, South Korea had a nuclear-installed capacity of more than 23 GW across 24 reactors. 5 GW of nuclear capacity are under construction in the country.
