BEIJING (Reuters) - The nuclear energy industry needs an annual investment of $80 billion in order to meet climate change goals, the director of the International Atomic Energy Agency (IAEA) said on Friday.

Dohee Hahn told a nuclear industry conference that between 10 and 20 reactors will need to be built every year through 2030, if the global temperature rise is to be held within 2 degrees.

The agency estimates that total global nuclear capacity needs to reach 862 gigawatts by 2040, up from 376 gigawatts in 2014, in order to meet the goals set in the Paris agreement.
