More than 30 countries -- including European nations, the United States, Brazil and China -- took part on Thursday in the first-ever summit held by the United Nations' atomic energy agency to promote nuclear as a "clean and reliable source of energy".
"This is a fight where we have to use all the available, dispatchable, CO2-free energy sources for the common challenge," International Atomic Energy Agency (IAEA) head Rafael Grossi told the gathering at the Atomium in Brussels -- a modernist landmark built for the 1958 World Fair.
