A 615-megawatt reactor lost its cooling towers, its transformer and its power lines to a teardown crew, so rebuilding all three to get it on the grid by early 2029 takes up to $1.9 billion in federal money, the biggest check any American restart has drawn

By Luis Reyes — Sep 13, 2026

An 850-megawatt battery pushed 700 megawatts into the grid for two straight hours on Friday and then pulled almost 850 back out of it, its second full-power test in three days, nearly eleven months after a transformer failure cut its grid contract in half

A 1,014-megawatt nuclear plant on the Finnish coast is pulling the casings and internals out of all eight of its low-pressure turbines during an outage that keeps one reactor running, and the rebuild adds 38 megawatts while the reactors make exactly the same heat

By Luis Reyes — Sep 12, 2026

A 20-foot container outside Brisbane holds liquid sodium and liquid sulfur at up to 645 degrees, keeps itself that hot on under three kilowatts and stores 1,450 kilowatt-hours, and the only company that still builds them has voted to stop, with the last one shipping next January

By Luis Reyes — Sep 12, 2026

An Oregon wave-power site opened seven miles off the coast with nearly 50 miles of cable buried under the seafloor and four berths rated at 5 megawatts each, not one machine is in the water, and the first one likely to go in would use one percent of what the cables can carry

By Luis Reyes — Sep 11, 2026

A British fusion machine ran more than 1,100 plasmas at 54 million degrees, held the edge steady four separate ways so it stopped throwing the bursts that chew up the walls, and learned to find the plasma by reading the glow from the exhausts above and below it

An Italian reactor is being cut apart from above through 10 feet of water with a clamp on a pole and underwater cameras for eyes, the first 2,200 pounds of metal are already out, and the 157-foot steel ball around it is listed heritage that stays standing when the reactor is gone

By Luis Reyes — Sep 11, 2026

A 120-foot steel building stands over a sealed plutonium reactor in Washington state with open air between the two, put up for under $10 million to stay shut for up to 75 years, and the crew that checked the reactor’s roof flew a drone into that gap so nobody stood next to the core

By Luis Reyes — Sep 11, 2026

A Sydney factory roof grew 14,000 native plants under its 319 solar panels and they made 11 percent more electricity over the summer than a bare array, because the leaves cool the air under the glass, and on the hottest days the roof ran 50 degrees cooler than bare aluminum

By Luis Reyes — Sep 11, 2026

A 12-panel concrete wall just went up around a reactor vessel in Tennessee, cut in four designs with stepped and wavy seams so radiation can’t run straight out through the gaps, and robot arms overhead now connect the pipes with no one setting foot inside

By Luis Reyes — Sep 10, 2026

A French grower put 4,725 solar panels over 3.7 acres of yellow kiwifruit vines 2,400 feet up in the Alps, because the bacterium that kills a yellow vine within two seasons rides in on rain and gets in through hail wounds, and the roof that stops the rain traps the moisture it feeds on

By Luis Reyes — Sep 10, 2026

Two heat exchangers 74 feet tall and 470 tons each had to go into an Ohio reactor building with no door big enough for them, so crews cut a hole through the shield building and the steel containment, slid the old pair out and the new pair in, and welded the wall shut behind them

By Luis Reyes — Sep 10, 2026

A 42-foot nuclear pressure tank weighing 93 tons opens through a single 16-inch hatch, so when 30 heaters melted inside it and dripped copper onto the floor, the Swedish crew built a full-size copy to practice on, dropped tools down 39 feet on poles and sent a robot in to vacuum

By Luis Reyes — Sep 10, 2026

While the White House has asked Congress for $152 million to reopen Alcatraz as a prison, 959 solar panels sit on the cellhouse roof tilted five degrees so they stay below the parapet, and the island that once took 2,000 gallons of diesel a week by boat now ships about 75 percent less

By Luis Reyes — Sep 10, 2026

A generator rotor spinning 3,000 times a minute inside a Finnish reactor failed, got replaced with the last spare in the building, and that one failed again seven months later, so the unit has run at 735 megawatts instead of 890 ever since, and the redesigned one is not due until late 2027

By Luis Reyes — Sep 9, 2026

New Jersey stood 378 solar panels dead upright in a cattle pasture, edge-on to the sun, because an upright panel gives you two production humps instead of one noon spike, and six cows are now grazing between the rows with a camera on them every five minutes

By Luis Reyes — Sep 9, 2026

A 36-mile concrete pipe feeds three desert reactors 72,000 acre-feet of treated city sewage a year, 95 percent of which goes up the cooling towers as vapor, and the contract behind that water runs out in 2050, 17 years before the owner has asked to keep the reactors running

By Luis Reyes — Sep 9, 2026

An Illinois reactor that regulators just cleared to run until 2049 was shut off by hand at 4:31 in the morning because an instrument said its control rods were moving when they weren’t, half its protection system fired on its own, and it was still at zero five days later

By Luis Reyes — Sep 9, 2026

While the only new reactors finished in the United States in three decades are AP1000s, the Chinese copy of that design got its 1,100-ton steel dome craned on 33 months after the construction license, with everything underneath it still to install

By Luis Reyes — Sep 9, 2026

A 10-foot-high field of solar panels covering 2.2 acres let a Massachusetts farmer pull sweet corn at about 80 percent of his open rows, at the same quality, while 832 modules on 28 tracker motors made 445 kilowatts over the same dirt

By Luis Reyes — Sep 8, 2026

Switzerland floated 1,400 solar panels on an Alpine reservoir at 5,940 feet, chained to weights on the bottom, because the lake belongs to a hydro plant that drains it every year, and for six months of every year the panels come down and sit on a gravel pad somebody dredged out of the lake to catch them

By Luis Reyes — Sep 8, 2026

A 240-megawatt reactor cooled by liquid sodium ran for 15 months beside a Nebraska coal plant and has sat under a 1.4-acre grass mound since 1969 with 300,000 curies inside, its drawings sealed in two stainless steel boxes, and the government still mows and waters the grass

By Luis Reyes — Sep 8, 2026

While a run of American microreactors went critical in Idaho this summer, a one-fifth-scale core built to cool itself with sealed tubes and no water did it in Nevada at 10:39 in the morning, made no usable heat, and ran inside the bunker built to assemble nuclear test devices

By Luis Reyes — Sep 8, 2026

An eight-foot livestock trough upside down over a six-foot one, with 18 inches of landscaping gravel packed between them, holds 100 kilowatt-hours of heat at 1,022 degrees. It has cycled more than 200 days in New Mexico and roasted a dark batch of coffee faster than gas did

By Luis Reyes — Sep 7, 2026

A californium wire under a tenth of an inch thick, rolled out on a jeweler’s mill, is what wakes up a new American reactor, and a microgram of it throws 2.3 million neutrons a second. One lab makes all of it, and one swapped molecule just halved the cleanup

By Luis Reyes — Sep 7, 2026

While solar panels ate 186.6 million ounces of silver last year, a lab wired cells together with a nickel tape thinner than a hair, stuck on cold with no solder, and after 200 cycles down to minus 40 the test module was under 1 percent down. The tape barely holds on

By Luis Reyes — Sep 7, 2026

Water boils at 202 degrees in Denver because there is a mile less air pressing on the pot, and a concrete building in eastern Washington takes that much further, boiling radioactive tank waste at 125. One run freed up 353,000 gallons of room underground

By Luis Reyes — Sep 7, 2026

A 164-foot concrete rotor turning in the tide makes no electricity at all. A federal lab opened its hub and found a bearing and nothing else, because the only two generators on the whole thing are bolted to the blade tips, where the water arrives fast

By Luis Reyes — Sep 7, 2026

A 70-foot room in Idaho full of argon, behind four feet of concrete, is where America cuts open used fuel rods, the cuts get marked with a Sharpie wrapped in tape, a plumber’s pipe cutter does the rough work, and it just got a plaque for a career that is not over

By Luis Reyes — Sep 6, 2026

Germany stood 64 solar panels upright along the fence of a public pool, facing the parking lot instead of the sky, because the back of each panel drinks the light bouncing off the cars, and they give up the middle of the day to take the early morning and late afternoon while 180 more roof three pergolas by the kids’ pool

By Luis Reyes — Sep 6, 2026

An 18-inch ceramic disc printed from silicon carbide sat on a tower ringed by 218 mirrors in the New Mexico desert, and the mirrors took two days to line up on it. Its face hit 2,534 degrees, the air coming out the back left at 1,562, and the program had paid for 2,012

By Luis Reyes — Sep 6, 2026

While a 4.6-ton robot arm goes in through a 22-inch hole at Fukushima for a few grams, crews at Hanford just lifted a 50-foot, 10-ton pump out of a radioactive waste tank, drilled holes in it on the way up to drain the liquid inside, and did in one day what they rehearsed for two years

By Luis Reyes — Sep 6, 2026

A 375-foot concrete tank in South Carolina, wrapped in 341 miles of cable like a wine barrel, is cleared to take 33 million gallons of nuclear grout that pushes outward as a liquid until it sets into a plug nobody moves. The sign-off came 26 months after the last pour

By Chema Bonilla Díaz — Sep 6, 2026

A 63-ton curtain of 504 solar panels will hang from steel cables 14.3 feet above an open tank of sewage in Vienna and pull itself back in 30 seconds when hail rolls in, because crews have to see the scum on the surface, and the whole thing makes what 25 American homes use in a year

By Luis Reyes — Sep 5, 2026

A 710-foot concrete wall on the Colorado River has 27.85 feet of water left above the line where its eight turbines shut down before vapor bubbles pit the steel. The lake behind it sits 40 feet from the bottom of a gauge never built to read water that low

By Luis Reyes — Sep 5, 2026

A 6-inch nickel can grew in a bath around a plastic mold, and acid dissolved the mold out from inside, leaving a container with no weld anywhere on it. Oak Ridge packed it with powder and squeezed out a 15.7-pound block of solid metal for a reactor

By Luis Reyes — Sep 5, 2026

A spring inside a nuclear plant breaker got acrylic paint instead of dye, the paint can flake into the contacts, and a breaker that still opens on demand may refuse to close, the move that powers the emergency pumps, so 13 plants from New Hampshire to Arizona have to check theirs

By Luis Reyes — Sep 5, 2026

A 6,560-foot hole in Cornish granite came up with 158-degree water carrying 100 parts per million of lithium, and a well in the same rock pulls 340. So a small British company hired a Texas oilfield crew to sink two more holes and pump for three months

By Luis Reyes — Sep 5, 2026

A 22-micrometer strip of nickel-titanium shortens on its own when a 266-degree plate warms it, and it yanks a second strip that snaps back 4 degrees colder than the room. The cooler built around the pair has no motor in it and moves 2.79 milliwatts

By Luis Reyes — Sep 5, 2026

Britain is dropping 14 modules of 17.6 tons apiece and a 60.6-ton gantry crane into the building that replaces the filter cleaning its most hazardous nuclear site, now three quarters built — the old one was designed for 25 years, has run 41, and nothing takes over until 2030

By Luis Reyes — Sep 4, 2026

A 62,900-ton bulk carrier crossed 8,500 nautical miles from Singapore to Ghana on 24 percent less oil, after a hydrogen rig went on in two weeks with the ship still floating and nothing in the hull or the engine touched

By Luis Reyes — Sep 4, 2026

A well 19,448 feet long, drilled straight down into Utah and then turned sideways for 7,500 feet of it, is pushing water into rock at 460 degrees and taking it back out at more than 400, on rigs and pumping spreads that came out of the oil patch. There is no oil under it

By Luis Reyes — Sep 4, 2026

A reactor that gets colder is a reactor that wants to start back up, so baskets of ceramic pellets bolted to a 700-ton containment wall dissolve into the steam running down it and feed boron back into a core that has 76 feet of vessel above it, with no pump in the chain

By Luis Reyes — Sep 4, 2026

A fission reactor the size of a 20-foot shipping container went critical in Idaho 150 days after the project started, makes one megawatt, ships on an ordinary truck, swaps its core every five years and runs on the same 4.95 percent fuel every US plant already burns

By Luis Reyes — Sep 4, 2026

A 50-megawatt nuclear station gets built inside a shipyard, sails to the Canadian coast as cargo on a heavy-lift ship and gets bolted to the shore before a single fuel pellet goes near it, and sails off to a factory to be taken apart when it dies

By Luis Reyes — Sep 3, 2026

An American startup says it made uranium hexafluoride without touching elemental fluorine, the element every other converter has to brew on site by running current through acid, and it wants a pilot plant in Idaho making 550 tons of uranium a year. It has not said how, or how much it made
