NASA and the U.S. Department of Energy (DOE) are collaborating to advance space-based nuclear technologies.

Quantum sensors can now detect signals of arbitrary frequencies thanks to a quantum version of frequency mixing—a widely used technique in electronics.

Monitoring the fissile material aboard nuclear-powered submarines is notoriously difficult. Researchers may now have a way to safeguard this weapons-grade substance.

Monitoring the fissile material aboard nuclear-powered submarines is notoriously difficult. Researchers may now have a way to safeguard this weapons-grade substance.

Last year, the United Kingdom and the United States agreed to transfer some of their nuclear-powered submarines to Australia, a country that, at that time, possessed none. On hearing the announcement, Bernadette Cogswell and Patrick Huber of Virginia Tech in Blacksburg say that they were immediately concerned as there is currently no easy way to safeguard a nuclear reactor aboard a submarine. Now, the duo has come up with a technique that could solve that problem [1]. They say that the method could be used to confirm the presence of a submarine’s nuclear core without the need for onboard monitoring.

Most naval nuclear reactors employ uranium that is highly enriched fissile uranium-235 (235U 2 3 5 U 235U), a material also used to make nuclear weapons. For land-based reactors, inspectors keep track of 235U 2 3 5 U 235U using neutrino detectors placed close to an operating core (see Feature: Neutrino Detectors for National Security). But this technique doesn’t work for the water-submerged cores in submarines at sea. It also fails for the weak signals from powered-down cores, allowing operators to subvert checks of docked submarines.

The world’s leading powers are investing in nuclear fusion and working to resolve the engineering challenges associated with it. If successful, nuclear fusion can provide nearly limitless energy with minimal waste.

Nuclear power has a controversial history, but many energy experts say it has a major role to play in our energy future. Some in the industry are working to make standard fission power safer and cheaper. Others are pursuing the holy grail of energy — nuclear fusion, the process that powers the sun and the stars. If we figure out how to harness that power here on earth, it would be a huge game-changer.

Nuclear fusion is a widely studied process through which atomic nuclei of a low atomic number fuse together to form a heavier nucleus, while releasing a large amount of energy. Nuclear fusion reactions can be produced using a method known as inertial confinement fusion, which entails the use of powerful lasers to implode a fuel capsule and produce plasma.

Researchers at Massachusetts Institute of Technology (MIT), University of Delaware, University of Rochester, the Lawrence Livermore National Laboratory, Imperial College London, and University of Rome La Sapienza have recently showed what happens to this implosion when one applies a strong magnetic field to the fuel capsule used for inertial confinement fusion. Their paper, published in Physical Review Letters, demonstrates that strong magnetic fields flatten the shape of inertial fusion implosions.

“In inertial confinement fusion, a millimeter-size spherical capsule is imploded using high-power lasers for nuclear fusion,” Arijit Bose, one of the researchers who carried out the study, told Phys.org. “Applying a magnetic field to the implosions can strap the charged plasma particles to the B-field and improve their chances of fusion. However, since magnetic field can restrict plasma particle motion only in the direction across the field lines and not in the direction along the applied field lines, this can introduce differences between the two directions that affect the implosion shape.”

Artificial intelligence is playing a huge role in the development of all kinds of technologies. It can be combined with deep learning techniques to do amazing things that have the potential to improve all our lives. Things like learning how to safely control nuclear fusion (opens in new tab), or making delicious pizzas (opens in new tab).
