Nations are racing to deploy advanced reactors for cleaner, more secure nuclear energy, which ...

Nuclear fusion, the process that powers every star in the observable universe, has moved from theoretical physics into the realm of real laboratory results. On December 5, 2022, scientists achieved ...

Few manmade threats inspire as much fear as the potential of a nuclear meltdown. The fact that "Chernobyl," once an obscure Ukrainian town, is now globally recognized as a synonym for catastrophe ...

Nuclear energy is often regarded as the cleanest power source on Earth. Unlike coal or gas, nuclear power plants don't release smoke and other contaminants into the air. They produce massive amounts ...

In 2025, IAEA website audiences were drawn in large numbers to our visual science explainers and features on the safe and secure uses of nuclear energy, nuclear science and technology. 1.

Nuclear power’s “cheap, clean, and secure” promise is breaking down. Small modular reactors (SMRs) remain largely theoretical, with the only advanced U.S. project cancelled over high costs. Renewables ...

Three major nuclear reactor accidents—Three Mile Island (1979 in the United States), Chernobyl (1986 in Ukraine, then part of the Soviet Union), and Fukushima Dai-ichi (2011 in Japan)—significantly ...

The U.K. once had more nuclear power stations than the U.S., USSR and France combined but hasn't completed a reactor since 1995. Nuclear energy accounted for 14% of the U.K.'s power supply in 2023 but ...

Project Pele, the Department of War’s (DOW’s) first-of-its-kind transportable nuclear microreactor prototype, has received its tri-structural isotropic (TRISO) particle fuel at Idaho National ...
