Scientists are searching for new materials to advance the next generation of nuclear power plants. In a recent study, researchers at the Department of Energy’s Argonne National Laboratory showed how artificial intelligence could help pinpoint the right types of molten salts, a key component for advanced nuclear reactors.

Russia has begun construction of protected covering at Ukraine’s Zaporizhzhia nuclear power plant, according to a December 17 report from Russian news outlet RT. The story has been picked up in the West by some news agencies but has not been widely circulated.
Vladimir Rogov, a Russian-appointed official in Zaporizhzhia Oblast, said, “Russia is constructing a protective dome over spent radioactive fuel stores at the [Zaporizhzhia] nuclear power plant as Ukrainian forces continue to target the facility.”

A study published recently in the American Physical Society journal Physical Review C reveals new findings about the strong nuclear force, the mysterious fundamental force that holds together the protons and neutrons of the atomic nucleus. Experiments conducted at Argonne National Laboratory have shown how the round, heavy nuclei of the nickel-64 isotope (containing 28 protons and 36 neutrons, making it the heaviest stable Ni isotope) changed into one of two shapes—either like a doorknob or a football—depending on the amount of energy exerted on it. A summary of the research on the Phys.org website compares the nuclei shape change to popcorn kernels changing shape when heated in a microwave.

Advancing its efforts to develop the Arctic and establish new energy markets, Russia launched a new nuclear-powered icebreaker, the Yakutia, in St. Petersburg during a November 22 ceremony. At the launching in the northern Russian port city, the Russian flag was raised on another nuclear icebreaker, the Ural. Overseeing the events via video link from the Kremlin, Russian president Vladimir Putin said that the icebreakers “were laid down as part of a large serial project and are part of our large-scale, systematic work to reequip and replenish the domestic icebreaker fleet, to strengthen Russia's status as a great Arctic power.”

Nuclear fusion “might actually be on the cusp of commercial viability” today, says a recent article in Fortune magazine. The article offers a brief review of recent technical and entrepreneurial developments in fusion energy. It also places these developments in perspective regarding the hurdles that remain before commercialization can be realized.

A study recently published in Nature Communications brings a new perspective on how radiation travels through dense plasmas, potentially leading to a better understanding of the evolution of stars and the development of controlled nuclear fusion reactions. Researchers led by investigators at the University of Rochester Laboratory for Laser Energetics (LLE) achieved their findings by conducting experiments with LLE’s OMEGA laser system. This extensive system, which is 19 meters tall and 70 meters long, consists of 60 laser beams that can focus as much as 30,000 joules of energy onto a target for the study of nuclear and fluid dynamic events.
