Lithium-6 is essential for producing nuclear fusion fuel, but isolating it from the much more common isotope, lithium-7, usually requires liquid mercury, which is extremely toxic. Now, researchers have developed a mercury-free method to isolate lithium-6 that is as effective as the conventional method. The new method is presented March 20 in the Cell Press journal Chem. "This is a step towards addressing a major roadblock to nuclear energy," says chemist and senior author Sarbajit Banerjee of ETH Zürich and Texas A&M University. "Lithium-6 is a critical material for the renaissance of nuclear energy, and this method could represent a viable approach to isotope separation."

New poppy seed-sized fuel pellets could power nuclear reactors on the moon

Scientists have developed a nuclear fuel source no larger than a seed, which NASA will test for use in future moon missions.

Scientists in the U.K. have created mini, seed-sized nuclear fuel cells that could power futuristic flower-shaped reactors on the moon as soon as 2030. The tiny new fuel cells, developed by researchers at the Nuclear Futures Institute at Bangor University in Wales, are roughly the size of poppy seeds, which are around 0.04 inch (1 millimeter) across. The mini pellets are a type of tri-structural isotropic particle (TRISO) fuel, which is made from uranium, carbon and oxygen surrounded by a hard, ceramic-like shell. The cells are much more durable and efficient than traditional nuclear fuels, which makes them perfect for space exploration. The fuel cells are designed to power the Space Flower Moon Micro Reactor, a conceptual car-sized fusion reactor designed by Rolls-Royce. Funding for the reactor was secured in early March, and the design is a leading candidate to power future moon bases as a part of NASA's Artemis program, which aims to establish a permanent base on the moon by 2030. Researchers think one of the durable pellets could power a single reactor for up to 15 years.

Although it generated power, the first nuclear reactor to do so, Experimental Breeder Reactor Number One was above all an experiment. We see here, not only the creation of a new core design to test a scientific hypothesis, but also a great amount of painstaking handwork, which would be totally uneconomical for real-world power production. Unsurprisingly, a major focus of Experimental Breeder Reactor Number Two was on simplifications which would reduce the fuel cycle cost!
