In August, Japan reopened its first nuclear reactors after an almost two-year hiatus that followed the 2011 earthquake and tsunami. Now, months later, Kyushu Electric Power Co. is preparing to guard the controversial energy source against terrorist attacks, too.
Exactly half a century ago this week, a rocket shot off from the California coast. It carried the U.S.’s first and only (known) space nuclear reactor, SNAP-10A, which has been circling the Earth ever since and will continue to circle for another 3,000 years.
This video explainer by Kurz Gesagt focuses on why nuclear energy is actually terrible and something we should stop using because it's so bad. The reasons are pretty obvious: nuclear energy leads to nuclear bombs, nuclear waste is really dangerous and nuclear accidents and disasters are catastrophic.
Nuclear energy is great! Nuclear energy is terrible! There are two sides to the argument and Kurz Gesagt is breaking down both perspectives with point/counterpoint video explainers. The three reasons why nuclear energy is awesome and why we need more? It saves lives. It helps the environment. And that using it could…
Our ability to harness nuclear energy has existed for quite a while now and yet nuclear energy is only responsible for providing 10% of the world's energy. There are 439 nuclear reactors spread across 31 countries with 160 more reactors planned for the future and yet nuclear energy has stagnated since the 80's. What…
The Department Of Energy posted 21 photos onto its Flickr page a few weeks ago about Chicago Pile-1, the site of the first human-made, self-sustaining nuclear reaction, located in Chicago.
What would you do if your boss handed you a mysterious box and said that if anything weird started happening with it, to just ditch the thing and run as fast as you can? Well that's exactly what happened to a poor courier working for the Manhattan Project back in the 1940s — a courier who, as it turns out, was…
The Uranium-235 and -238 we use in modern nuclear fission reactors are humanity's single most energy-dense fuel source (1,546,000,000 MJ/L), but that potent power potential comes at a steep price—and not just during natural disasters. Its radioactive plutonium byproducts remain lethally irradiated for millennia.…
Every day, an army of computers and human operators toil in control rooms, providing electricity to a city, guiding planes across the sky, or searching for the Higgs-Boson. These rooms are all extremely important, whether they're making breakthrough discoveries or just keeping the lights on.
Somewhere around 75 percent of U.S. nuclear power plants have been found leaking the radioactive element Tritium into the ground to various extents. Corroded piping buried underground seems to be the main problem, and a problem that can affect groundwater if ignored.
Alabama's Tennessee Valley Authority is trying to find an alternative to 18 coal plants which are currently providing power to the Yellowhammer state. They think resurrecting the Bellefonte 1 nuclear power plant that's lain dormant for 23 years is the answer. Huh.
Despite recent rallies against Japan's nuclear energy dependency, the country's Industry Minister says its reactors will remain online indefinitely. Furthermore, the country will do its "utmost" to keep them that way. I mean, what could go wrong? [Kyodo News]
Much of the US government is determined to prove Iran guilty of nuclear weaponry. We've hidden sensors in their cities, watched them from space, and sent spies. And after all that, the New Yorker reports, we can't dig up proof.
At the TED Conference last year Bill Gates unleashed a swarm of mosquitoes to demonstrate a point about malaria. This year, he's taking on CO2 in a big way. And he brought fireflies.
Cold fusion, the act of producing a nuclear reaction at room temperature, has long been relegated to science fiction after researchers were unable to recreate the experiment that first "discovered" the phenomenon. But a Japanese scientist was supposedly able to start a cold fusion reaction earlier this week, which—if…
