Japan has restarted its first nuclear reactor since the Fukushima disaster of 2011. The number one reactor at Sendai Nuclear Power Plant was brought back online under stringent new safety guidelines – the cost of these new safety systems exceeded US$100m at Sendai alone.

Whilst the majority of Japan’s reactors remain offline, which country in the world has the most nuclear power reactors?

The USA tops the list, with nearly 100 operational nuclear reactors, providing a total net electricity capacity of 98,708 megawatts. Next on the list is France, with 58 reactors, and Japan is in third place, though, as of 11 August, only one reactor out of 43 is online. Worldwide there are currently 438 operational nuclear reactors, with a further 67 under construction.

This data is taken from the International Atomic Energy Agency’s Power Reactor Information System, which was last updated on 8 August 2015.
