If you're decommissioning a nuclear site, it would be nice to be able to call on Iron Man. But since he's a comic book character, researchers at the University of Bristol are proposing the next best thing – an armored exoskeleton that would protect workers from radioactive contamination, while also reducing fatigue and providing vital information through helmet-mounted augmented reality di
Additive manufacturing is taking to the seas with the first 3D-printed part being cleared for installation aboard a US Navy nuclear aircraft carrier. Built by Huntington Ingalls Industries' Newport News Shipbuilding division and the Navy, the prototype piping assembly will be installed on the USS Harry S. Truman (CVN 75) early next year, where it will be subjected to 12 months of operation
NASA's Mars 2020 rover has received its nuclear power plant developed by Aerojet Rocketdyne and Teledyne. The Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) unit will provide the robotic spacecraft with 125 W of electricity to operate the drive motors and power the onboard systems, as well as provide heat to keep the electronics warm during the sub-arctic Martian nights... Con
One of the possible pathways to limitless and clean energy can be found in hollow, doughnut-shaped chambers known as tokamak nuclear fusion reactors. A relatively new player on the scene, a UK company called Tokamak Energy, is claiming a new milestone in the area after heating its ST40 device to 15 million degrees Celsius, similar to temperatures found at the center of the Sun...

Imagine only replacing the batteries in a device once a decade, or even once a century. Nuclear batteries could one day let us do just that, but their power density is currently too low to be very practical. Now, Russian researchers have developed a new nuclear battery design based on nickel-63, which has a higher specific energy than regular, commercially-available batteries... Continue R
The Cold War left behind significant amounts of low-level nuclear waste, but the future may be a bit cleaner thanks to a team of scientists at the US Department of Energy's Pacific Northwest National Laboratory (PNNL), who have vitrified low-level radioactive waste for the first time in a continuous process. In a laboratory set up, 3 gal (11.4 L) of waste taken from a tank at the decommiss
Last weekend, Russia's floating nuclear power plant, the Akademik Lomonosov, was towed out to sea for the first time, beginning its voyage from St Petersburg to Murmansk, where it will be eventually loaded up with nuclear fuel and started up sometime in 2019...

The 99 nuclear power plants on US soil provide nearly 20 percent of the country's energy needs and have been operating at an increasingly high capacity, from 50 percent in the early 70s, to 70 percent in the early 90s, and keeping above 90 percent since 2002. However, according to new research from MIT and the Argonne National Laboratory, throttling down the capacity of nuclear power plant
During the historic nuclear arms negotiations in the 1980s between the United States and the Soviet Union, "trust, but verify" became a common phrase. Today, with control of the spread of nuclear weapons as urgent a problem as ever, MIT researchers are working on a system similar to computer encryption that allows arms inspectors to keep track of nuclear warheads without their owners worry
A consortium of American and British science institutions, led by the Lawrence Livermore National Laboratory (LLNL), is working on a way to use antineutrinos to remotely monitor nuclear reactors. Sponsored by the US Department of Energy's National Nuclear Security Administration, the Advanced Instrumentation Testbed (AIT) program is installing the 3,500-ton WATer CHerenkov Monitor of ANtineut
