Plans For New Reactors Worldwide

  • About 65 reactors are under construction across the world. About 90 further reactors are planned.
  • Most reactors under construction or planned are in Asia.
  • New plants coming online in recent years have largely been balanced by old plants being retired. Over the past 20 years, 106 reactors were retired as 102 started operation.

Today there are about 440 nuclear power reactors operating in 31 countries plus Taiwan, with a combined capacity of about 400 GWe. In 2023 these provided 2602 TWh, about 9% of the world's electricity.

Many countries with existing nuclear power programmes either have plans to, or are building, new power reactors. Every country worldwide that has operating nuclear power plants, or plants under construction, has a dedicated country profile in the Information Library.

About 30 countries are considering, planning or starting nuclear power programmes. For more information see page on Emerging Nuclear Energy Countries.

Nuclear reactors under construction

About 65 power reactors are currently being constructed in 15 countries.
