The UN’s IAEA has reported that Iran has 55.6 kilograms (122.6 pounds) of 60% enriched uranium. The body says this means Iran is able to produce up to 25 kg (55 lbs) of 90% enriched uranium, enough for a nuclear bomb. The real story could be even more concerning. Consider the hoary phrase, “There’s more than one way to skin a cat.” Similarly, there’s more than one way to make a nuclear bomb. The Union of Concerned Scientists has said that it might be possible to produce a fission-type nuclear weapon with as little as 15kg (33 lbs) of highly...

Scientists have discovered a new type of uranium that is the lightest ever known. The discovery could reveal more about a weird alpha particle that gets ejected from certain radioactive elements as they decay. The newfound uranium, called uranium-214, is an isotope, or a variant of the element, with 30 more neutrons than protons, one fewer neutron than the next-lightest known uranium isotope. Because neutrons have mass, uranium-214 is much lighter than more common uranium isotopes, including uranium-235, which is used in nuclear reactors and has 51 extra neutrons. This newfound isotope isn't just lighter than others, but it also...

With NASA planning its next human mission to the moon in 2024, researchers are looking for options to power settlements on the lunar surface. According to a new article in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, nuclear fission reactors have emerged as top candidates to generate electricity in space. When it comes to powering an astronauts’ settlement, there are many factors to consider, writes correspondent Tien Nguyen in collaboration with ACS Central Science. The power source must be capable of being transported safely from Earth and of withstanding the harsh conditions of other worlds....

SHINKOLOBWE, Congo (AP) - Business is booming in the mining zone that supplied uranium for the atomic bombs unleashed on Hiroshima and Nagasaki - despite a decree by Congo's president banning all mining activity here. President Joseph Kabila ordered the zone closed three months ago amid growing concerns that unregulated nuclear materials could get into the hands of so-called rogue nations or terrorist groups. Yet 1,000 miles away from the capital, Kinshasa, thousands of diggers are still hacking away at a dark cavity of open earth in this southeastern village, filling thousands of burlap sacks a day with black soil...
