The world's largest nuclear power plant is shutting down a reactor due to a glitch. The No. 6 reactor at Japan's Kashiwazaki-Kariwa plant restarted Wednesday for the first time since the 2011 Fukushima disaster.

The United States runs the largest nuclear power fleet on the planet, but even basic questions about how many plants are actually operating can produce different answers. Some counts focus on plant sites,

The utility that operates the Fukushima plant that melted down in 2011 restarted a reactor at the world’s largest nuclear power plant, which it also operates in north-central Japan

Serbia will speed up preparations for its first nuclear power plants as it faces a surge in consumption even while attempting to phase out outdated, thermal-power units, said President Aleksandar Vucic.

It’s worth looking at high-assay low-enriched uranium, or HALEU, specifically. This fuel is enriched to higher concentrations of fissile uranium than conventional nuclear fuel, with a proportion of the isotope U-235 that falls between 5% and 20%. (In conventional fuel, it’s below 5%.)

Korea Hydro & Nuclear Power has launched a bidding process to select the host cities or towns for two new large nuclear power reactors. The announcement came just days after the government confirmed plans to construct the reactors by 2038.

Japan will switch the world's largest nuclear power plant back on next week, after a glitch with an alarm forced the suspension of its first restart since the 2011 Fukushima disaster.

An international nuclear power services company has confirmed it plans to submit an application to build new generation capacity at a long-closed nuclear power plant in Wisconsin.

AI is driving unprecedented investment for massive data centers and an energy supply that can support its huge computational appetite. One potential source of electricity for these facilities is next-generation nuclear power plants,

EADaily, February 7th, 2026. All nuclear power plants in Ukraine were forced to stop generating electricity, as key high-voltage substations providing communication between nuclear power plants and the national energy system failed.
