Nuclear fission
☢️ Microreactor went from idea to chain reaction in under a year
American nuclear power has long been marked by delays, where a single reactor design could take a decade to test. Antares' microreactor Mark-0 started a stable nuclear reaction in under twelve months. That made them the first private company to take an advanced reactor there within the program.
☢️ Forty years after the disaster, Chernobyl teems with wildlife
Forty years after the accident at the nuclear power plant, the area around Chernobyl remains too dangerous for human habitation. But the wildlife has moved back in. Przewalski's horses, wolves, bears, lynx, moose, and red deer roam freely in the Chernobyl zone.
⚡ Finland has cut power sector emissions by 80 percent in a decade
Finland's emissions from electricity generation fell from nearly 15 million tonnes to around 3 million tonnes per year between 2016 and 2025. Nuclear and wind power together account for 64.5 percent of generation. The last coal plant was shut down in April 2025.
☢️ Nuclear reactor creates its own fuel from common thorium
A 2 megawatt reactor in the Gobi Desert converts thorium into uranium-233 inside the reactor while producing energy, which means it creates new fuel continuously. Thorium is much more common than uranium.
☢️ New battery converts nuclear waste radiation into electricity
There are hundreds of thousands of tons of spent nuclear fuel in the world, and the majority is stored unprocessed despite still retaining most of its energy. The technology may be particularly useful in environments where traditional power sources don't work, such as in deep seas or in space.
☢️ First generation four reactor begins construction in the USA
Kairos Power starts building Hermes, the first Generation Four reactor approved in the USA. The reactor uses a new combination of fuel and coolant for increased safety and simpler design. With Generation IV, what is now seen as a problem, nuclear waste, is transformed into a resource.
⚡ Record decrease in emissions from the EU's energy sector - renewables exceed 40%
Record decrease in coal, gas, and CO2 emissions in 2023 resulted in the EU's cleanest electricity mix ever. Emissions from the power sector have now nearly halved (-46 percent) since their peak in 2007.
⚡ World's first fourth-generation nuclear reactor starts up
Commercial operations have started at a new generation nuclear reactor that is the first of its kind in the world.
☢️ Rolls-Royce plans new nuclear power in Sweden - could be SMR at Marviken
For several decades, Rolls-Royce has been constructing small nuclear reactors, which are found on British nuclear submarines, among other places. Now, they plan to start building small modular reactors on land as well, and some of these may be placed in Marviken, Sweden.
