According to IAEA calculations, it is necessary to double the number of nuclear reactors in the world - currently at about 400 units - to achieve the objectives of the Paris climate agreement, Grossi said at the World Nuclear Exhibition in Paris. //

"We already have 10 countries which have entered the decision phase (to build nuclear power plants) and 17 others which are in the evaluation process," he said.

"There will be a dozen or 13 (new) nuclear countries within a few years," he added.

Ghana, Kenya, Morocco, Nigeria, Namibia, the Philippines, Kazakhstan and Uzbekistan were cited by Grossi as potential new nuclear countries.
