GE Vernova, which leads Global Nuclear Fuel (GNF) with partner Hitachi, announced February 14 that GNF has received approval from the Nuclear Regulatory Commission to manufacture, ship, and analyze the performance of nuclear fuel enriched with up to 8 percent uranium-235.
Three people were arrested on January 3 when they paraglided onto the site of a canceled nuclear power plant in Hartsville, Tenn., according to Nashville news station WSMV.

When my book Shorting the Grid was published in 2020, many described it as “alarmist.” Most people in the United States took grid reliability for granted. Sure, there were always power outages during storms, but weird things like “rolling blackouts” only happened in California.
Public perception is changing, however. Part of this change is due to the major February 2021 blackout in Texas, as well as the grid emergencies during December 2022. People became aware that their own grid could have problems, and not just the usual power-line-fails-in-a-snowstorm type of problems. For example, last December, the service areas for Duke Energy and the Tennessee Valley Authority in the southeastern U.S. experienced rolling blackouts. Grid operators had to take emergency measures. The Midwest, Texas, and New England experienced near misses with grid trouble. In other words, most of the country was at risk of rolling blackouts due to one relatively short winter storm.
Lightbridge Corporation, which is continuing to work closely with national laboratories on the manufacture and testing of its metallic fuel rod designs for light water reactors, just announced the results of an investigation on the casting process for molten uranium and zirconium with Pacific Northwest National Laboratory under the Department of Energy’s Gateway for Accelerated Innovation in Nuclear (GAIN) program.
Entergy’s River Bend nuclear power plant started its 22nd scheduled refueling and maintenance outage on February 11. The plant, located in St. Francisville, La., is a 967-MWe General Electric boiling water reactor.
"At 1:23 p.m. load dissipaters from the generator were connected—electricity flows from atomic energy.” These were the words Walter Zinn wrote in the log after the first four light bulbs were illuminated by nuclear energy. The year was 1951, and the EBR-I was about to show the world what nuclear energy had to offer.
The process of making fuel for our light-water nuclear plants is meticulously developed and executed. And as anyone who has gone through the receipt process once it arrives at the plant can attest, the initial quality examination is likewise a thorough and rigorous activity. We do a great job of making sure that high quality fuel is ready to go into the core.

It was a rather normal day back on March 11, 2011, at the Fukushima Daiichi nuclear plant before 2:45 p.m. That was the time when the Great Tohoku Earthquake struck, followed by a massive tsunami that caused three reactor meltdowns and forever changed the nuclear power industry in Japan and worldwide. Now, 10 years later, much has been learned and done to improve nuclear safety, and despite many challenges, significant progress is being made to decontaminate and defuel the extensively damaged Fukushima Daiichi reactor site. This is a summary of what happened, progress to date, current situation, and the outlook for the future there.

When Floyd Harris began working at Duke Energy’s Brunswick nuclear plant about 24 years ago as a radiation protection technician, robotics and remote monitoring were considered tools for radiation protection and nothing more. Now, teams from across the site, including engineering, maintenance, and operations, rely on the system of robots and cameras Harris is responsible for. “If you want to put those technologies under one umbrella,” says Harris, who now holds the title of nuclear station scientist, “it would be monitoring plant conditions.”
That monitoring is critical to effective plant maintenance. As Plant Manager Jay Ratliff explains, the goal is to “find a problem before it finds us” and ensure safety and reliability. Nuclear News Staff Writer Susan Gallier talked with Ratliff and Harris about how robotics and remote systems are deployed to meet those goals.
At Brunswick, which hosts GE-designed boiling water reactors in Southport, N.C., ingenuity and hard work have produced a novel remote dosimetry turnstile to control access to high-radiation areas, an extensive network to handle data from monitoring cameras, rapid fleetwide access to camera feeds to support collaboration, and new applications for robots and drones.
