It’s worth looking at high-assay low-enriched uranium, or HALEU, specifically. This fuel is enriched to higher concentrations ...

Nuclear power plants can provide a continuous and reliable supply of energy because they operate at full capacity nearly uninterrupted. This contrasts with variable renewable energy sources, such as ...

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 ...

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 ...

The biggest nuclear power plant in the United States is not a single hulking reactor, but a sprawling complex whose scale is measured in gigawatts and square miles. Its turbines quietly push out ...

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 ...

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 ...
