DUBAI, United Arab Emirates (AP) — The world wants more nuclear energy as a means to fight climate change and supply an ever-growing demand for electricity, part of a generational shift in thinking on atomic power, the head of the United Nations nuclear watchdog said Thursday.

Rafael Mariano Grossi, the director-general of the International Atomic Energy Agency, made the comments in an interview with The Associated Press at the COP28 climate talks. He called the inclusion of nuclear power at the summit, where he said a major nuclear agreement was likely, showed just how far the formerly “taboo” subject had come decades after the disasters at Three Mile Island and Chernobyl.

However, he acknowledged the challenge still posed for his agency in monitoring nuclear programs in countries, particularly in Iran after the collapse of its 2015 nuclear deal with world powers.

“This used to be easier when this international consensus was there and so Iran could see that this was not about political pressure, but a widespread approach that was to see a Middle East, one of the — if not the most — volatile region in the world, not to add to the mix the possibility of a country getting nuclear weapons,” Grossi said.
