Plans For New Reactors Worldwide
- About 80 reactors are under construction across the world. About 120 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, 111 reactors were retired as 101 started operation.
Today there are about 440 nuclear power reactors operating in 31 countries, with a combined capacity of about 400 GWe. In 2024 these provided 2667 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 35 countries are considering, planning or starting nuclear power programmes. For more information see page on Emerging Nuclear Energy Countries.

About 120 power reactors with a total gross capacity of about 110 GWe are planned, and over 300 more are proposed. Most reactors currently planned are in countries in Asia, characterized by fast-growing economies and rapidly-rising electricity demand.
Planned = Approvals, funding or commitment in place, mostly expected to be in operation within the next 15 years.
Proposed = Specific programme or site proposals; timing very uncertain.
† Under Construction figures include a number of units where construction is currently suspended: Carem25 (Argentina); Angra 3 (Brazil); Ohma 1 and Shimane 3 (Japan); Khmelnitski 3&4 (Ukraine).
