The newest generation of lithium-ion batteries now being developed uses thin-film, solid-state technology and could soon safely power cell phones, electric vehicles, laptops, and other devices. However, like all batteries, solid-state lithium-ion batteries have a drawback: Impedance—electrical resistance—can build up as batteries are discharged and recharged, limiting the flow of electric current.

SwRI engineers used LIDAR point cloud data to reconstruct a high-resolution image of a facility that houses electric turbines at the nuclear power plant. 3D cubes, or voxels, on the left provide spatial information on the turbine facility. Point clouds were reconstructed to create the high-resolution image of the turbines on the right. SwRI specializes in data visualizations to identify damage and potential hazards following accidents at nuclear power plants and other hazardous facilities. (Graphic: SwRI)
During the EnRicH 2021 European Robotics Hackathon, Southwest Research Institute’s unmanned aircraft system (UAS or drone) explored and mapped the interior of a nuclear power plant, detecting radiation sources autonomously, without the aid of a human pilot.
SwRI’s UAS technology can potentially assist in life-saving search-and-rescue missions and hazardous inspections at industrial facilities and infrastructure following natural disasters and other incidents.

NASA and Idaho National Laboratory have just opened a competitive solicitation for U.S. nuclear and space industry leaders to develop innovative technologies for a fission surface power system that could be deployed on the surface of the moon by the end of the decade. Battelle Energy Alliance, the managing and operating contractor for INL, issued a request for proposals and announced the news on November 19. Proposals are due February 17.

By using a combination of physics-based modeling and advanced simulations, Texas A&M University researchers say they have found the key underlying factors that cause radiation damage to nuclear reactors, which could provide insight into designing more radiation-tolerant, high-performance materials.

A set of graphite rods was exposed to hot plasma in the DIII-D tokamak. Researchers measured the ablation behavior under extreme heat and particle flow to simulate conditions experienced by spacecraft heat shields during atmospheric entry. (Image: General Atomics)
As a spacecraft on a research mission hurtles at up to 100,000 miles per hour toward the surface of a gas giant like Jupiter, the atmospheric gases surrounding the spacecraft turn to plasma, and spacecraft temperatures increase to more than 10,000 °F.

Swapping conventional electromagnetic radiation for fast neutrons, a team of research engineers at Lancaster University in the United Kingdom, working with the Jozef Stefan Institute of Slovenia, report that they have successfully transmitted digital information wirelessly using nuclear radiation. The researchers’ attempts to transmit words and numbers using standard ASCII code “were 100 percent successful,” according to a November 10 press release from Lancaster University. Their research will be published in an upcoming issue of Nuclear Instruments and Methods in Physics Research and is now available online.

Researchers at the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) have developed a new model of how heat flows within plasmas. According to PPPL, the model could improve insights into the behavior of plasmas and may help engineers avoid the conditions that could lead to heat loss in future fusion facilities.

The United Kingdom has announced a shortlist of five sites as the potential future home of the U.K. Atomic Energy Authority’s (UKAEA) prototype fusion energy plant, the Spherical Tokamak for Energy Production (STEP). A final decision on the plant’s location is to be made by the U.K.’s secretary of state for business, energy and industrial strategy around the end of 2022.

Following a week of heightened attention to all things hydrogen preceding Hydrogen and Fuel Cell Day (October 8), Bernard Bigot, director general of the ITER Organization, published an op-ed on October 11 in The European Files, a magazine billed as an “effective work tool for European deciders.” Bigot’s article, “Hydrogen fusion: The way to a new energy future,” doubled as a fusion primer, promoting the technology as a future source of clean energy that is fueled by hydrogen and is capable of providing heat and power to produce more hydrogen.
