An anonymous reader quotes a report from Electrek: For the first time ever, renewable power generation -- that's wind, solar, hydro, biomass, and geothermal -- exceeded coal-fired generation in the US electric power sector in 2022, according to the US Energy Information Administration (EIA). Overall, the US electric power sector produced 4,090 million megawatt-hours (MWh) of power in 2022. Wind and solar's combined total generation increased from 12% in 2021 to 14% in 2022. Hydropower stayed the same last year at 6%, and biomass and geothermal also remained unchanged, at less than 1%. So that's a total of 21%. Utility-scale solar capacity in the US electric power sector -- the EIA doesn't include rooftop solar -- increased from 61 gigawatts (GW) in 2021 to 71 GW in 2022, according to EIA data. Wind capacity grew from 133 GW in 2021 to 141 GW in 2022. Coal-fired generation, on the other hand, dropped from 23% in 2021 to 20% in 2022 because a number of coal-fired power plants retired, and the plants still online were used less.

Renewables surpassed nuclear generation for the first time in 2021, and that trend continued last year. Nuclear dropped from 20% in 2021 to 19% in 2022 because Michigan's Palisades nuclear power plant was retired in May 2022. However, Palisades' new owner, Holtec, wants to restart it, and this idea is not proving particularly popular, with one environmental group saying that would risk a "Chernobyl-scale catastrophe." The Biden administration pledged $6 billion on March 2 to help extend the operating life of aging nuclear power plants in order to help the US combat climate change. However, natural gas is still the largest source of US electricity generation, and it grew from 37% in 2021 to 39% in 2022. This month, the EIA forecast that both wind and solar will each grow by 1% in 2023. Natural gas is forecast to remain unchanged, and coal is forecast to decline by 3% to 17% next year.

Saturday Arduino announced "a new, revolutionary revision of the iconic UNO board," promising "a long-awaited update on performance and possibilities." The Arduino UNO R4 indeed preserves the well-known features of the UNO family — standard form factor, shield compatibility, 5V operating voltage, outstanding robustness — while offering no less than a 32-bit Cortex-M4 and a 3-to-16x increase in clock speed, memory and flash storage....

The UNO R4 will come in two versions — UNO R4 WiFi and UNO R4 Minima — offering unprecedented performance and possibilities for the maker community. The WiFi version comes with an Espressif S3 WiFi module, expanding creative opportunities for makers, educators, and hobbyists alike; while the UNO R4 Minima provides a cost-effective option for those seeking the new microcontroller without additional features....

SRAM went from 2kB to 32kB, and flash memory went from 32kB to 256kB to accommodate more complex projects. In addition, following the requests from the community, the USB port was upgraded to the USB-C and maximum power supply voltage was increased to 24V with an improved thermal design. The board provides a CAN bus, which allows users to minimize wiring and execute different tasks in parallel by connecting multiple shields. Finally, the new board includes a 12-bit analog DAC.

All in all, Arduino UNO R4 is the answer to the requests for improvement and updates the developer and maker community has been advancing, making it easier than ever to get started with Arduino.... On the software side, a big effort is being made to maximize retrocompatibility of the most popular Arduino libraries so that users will be able to rely on existing code examples and tutorials.

The New York Times reports: Since January, the price of lithium has dropped nearly 20%, according to Benchmark Minerals, while sales of electric vehicles have soared. The price of cobalt, another important battery material, has fallen by more than half. Copper, essential to electric motors and batteries, has slipped by about 18%, at a time when U.S. mines and copper-rich countries such as Peru are struggling to increase production.

The price moves have confounded many analysts who predicted costs would stay high, or climb higher, slowing the transition to cleaner forms of transportation. Instead, the drop in commodity prices has made it easier for carmakers to cut prices for electric vehicles. This month, Tesla lowered the prices of its two most expensive cars, the Model S sedan and Model X sport utility vehicle, by thousands of dollars. That followed cuts in January by Tesla to its more affordable Model 3 and Model Y, and by Ford Motor to its Mustang Mach-E. The average price of an electric vehicle in the United States fell by $1,000 in February compared with January, according to Kelley Blue Book. "For electric vehicles, the major roadblock is cost," said Kang Sun, the CEO of Amprius Technologies, a young battery maker that this month announced plans for a factory in Colorado. The falling price of lithium, he said, "is going to promote EV sales."

Sun said he thinks prices could fall much further because demand for the metal has not risen as fast as some in the industry expected.... Ryan Melsert, CEO of American Battery Technology, attributed the recent decline in lithium prices to temporary factors like a seasonal slowdown in electric vehicle sales in China. "We expect to see very high prices for the foreseeable future," Melsert said. Vivek Chidambaram, the senior managing director for strategy at Accenture, the consulting firm, also expects the decline to be temporary. Lithium prices have fallen because sales of electric vehicles, while still brisk, are not growing as fast as automakers expected, he said. That has led suppliers to produce more than is needed.
The article notes America's Department of Energy is providing $3 billion in grants to create a domestic battery supply chain — partly because the supply of lithium has to increase 42-fold by 2050, according to the State Department's undersecretary for energy.

"We have to find additional sources of supply because 42 times is a lot," he tells the Times. "Right now, we don't have enough."

"With an 8-core Rockchip RK3588S SoC, the Orange Pi 5 is leaps and bounds faster than the aging Raspberry Pi 4," writes Phoronix: With up to 32GB of RAM, the Orange Pi 5 is also capable of serving for a more diverse user-base and even has enough potential for assembling a budget Arm Linux developer desktop. I've been testing out the Orange Pi 5 the past few weeks and it's quite fast and nice for its low price point.

The Orange Pi 5 single board computer was announced last year and went up for pre-ordering at the end of 2022.... When it comes to the software support, among the officially available options for the Orange Pi 5 are Orange Pi OS, Ubuntu, Debian, Android, and Armbian. Other ARM Linux distributions will surely see varying levels of support while even the readily available ISO selection offered by Orange Pi is off to a great start....

Granted, the Orange Pi developer community isn't as large as that of the Raspberry Pi community or the current range of accessories and documentation, but for those more concerned about features and performance, the Orange Pi 5 is extremely interesting.
The article includes Orange Pi 5 specs:

• A 26-pin header
• HDMI 2.1, Gigabit LAN, M.2 PCIe 2.0, and USB3 connectivity
• A Mali G510 MP4 graphics processor, "which has open-source driver hope via the Panfrost driver stack."
• Four different versions with 4GB, 8GB, 16GB, or 32GB of RAM using LPDDR4 or LPDDR4X. "The Orange Pi 4GB retails for ~$88, the Orange Pi 5 8GB version retails for $108, and the Orange Pi 5 16GB version retails for $138, while as of writing the 32GB version wasn't in stock."

In 169 performance benchmarks (compared to Raspberry Pi 4 boards), "this single board computer came out to delivering 2.85x the performance of the Raspberry Pi 400 overall." And through all this the average SoC temperature was 71 degrees with a peak of 85 degrees — without any extra heatsink or cooling.

Intel announced Friday that Gordon Moore, Intel's co-founder, has died at the age of 94: Moore and his longtime colleague Robert Noyce founded Intel in July 1968. Moore initially served as executive vice president until 1975, when he became president. In 1979, Moore was named chairman of the board and chief executive officer, posts he held until 1987, when he gave up the CEO position and continued as chairman. In 1997, Moore became chairman emeritus, stepping down in 2006.

During his lifetime, Moore also dedicated his focus and energy to philanthropy, particularly environmental conservation, science and patient care improvements. Along with his wife of 72 years, he established the Gordon and Betty Moore Foundation, which has donated more than $5.1 billion to charitable causes since its founding in 2000....

"Though he never aspired to be a household name, Gordon's vision and his life's work enabled the phenomenal innovation and technological developments that shape our everyday lives," said foundation president Harvey Fineberg. "Yet those historic achievements are only part of his legacy. His and Betty's generosity as philanthropists will shape the world for generations to come."

Pat Gelsinger, Intel CEO, said, "Gordon Moore defined the technology industry through his insight and vision. He was instrumental in revealing the power of transistors, and inspired technologists and entrepreneurs across the decades. We at Intel remain inspired by Moore's Law and intend to pursue it until the periodic table is exhausted...."

Prior to establishing Intel, Moore and Noyce participated in the founding of Fairchild Semiconductor, where they played central roles in the first commercial production of diffused silicon transistors and later the world's first commercially viable integrated circuits. The two had previously worked together under William Shockley, the co-inventor of the transistor and founder of Shockley Semiconductor, which was the first semiconductor company established in what would become Silicon Valley.

Huawei has reportedly completed work on electronic design automation (EDA) tools for laying out and making chips down to 14nm process nodes. The Register reports: Chinese media said the platform is one of 78 being developed by the telecoms equipment giant to replace American and European chip design toolkits that have become subject to export controls by the US and others. Huawei's EDA platform was reportedly revealed by rotating Chairman Xu Zhijun during a meeting in February, and later confirmed by media in China. [...] Huawei's focus on EDA software for 14nm and larger chips reflects the current state of China's semiconductor industry. State-backed foundry operator SMIC currently possesses the ability to produce 14nm chips at scale, although there have been some reports the company has had success developing a 7nm process node.

Today, the EDA market is largely controlled by three companies: California-based Synopsys and Cadence, as well as Germany's Siemens. According to the industry watchers at TrendForce, these three companies account for roughly 75 percent of the EDA market. And this poses a problem for Chinese chipmakers and foundries, which have steadily found themselves cut off from these tools. Synopsys and Cadence's EDA tech is already subject to several of these export controls, which were stiffened by the US Commerce Department last summer to include state-of-the-art gate-all-around (GAA) transistors. This January, the White House also reportedly stopped issuing export licenses to companies supplying the likes of Huawei.

This is particularly troublesome for Huawei, foundry operator SMIC, and memory vendor YMTC to name a few on the US Entity List, a roster of companies Uncle Sam would prefer you not to do business with. It leaves them unable to access recent and latest technologies, at the very least. So the development of a homegrown EDA platform for 14nm chips serves as insurance in case broader access to Western production platforms is cut off entirely.

Longtime Slashdot reader destinyland shares a report from Space.com: The Relativity Space rocket, called Terran 1, lifted off from Launch Complex 16 at Florida's Cape Canaveral Space Force Station at 8:25 p.m. EST (0025 GMT on March 23), kicking off a test flight called "Good Luck, Have Fun" (GLHF). Terran 1 performed well initially. For example, it survived Max-Q -- the part of flight during which the structural loads are highest on a rocket -- and its first and second stages separated successfully. But something went wrong shortly thereafter, at around three minutes into the flight, when the rocket failed to reach orbit.

"No one's ever attempted to launch a 3D-printed rocket into orbit, and, while we didn't make it all the way today, we gathered enough data to show that flying 3D-printed rockets is viable," Relativity Space's Arwa Tizani Kelly said during the company's launch webcast on Wednesday night. "We just completed a major step in proving to the world that 3D-printed rockets are structurally viable," she added.

An anonymous reader quotes a report from Ars Technica: Framework has delivered on the promise of its original 13-inch laptop. Three product generations in, the company has made a respectable competitor for the Dell XPS 13 or MacBook Air that can be repaired, modified, and upgraded, and owners of the original laptop can easily give themselves a significant performance boost by upgrading to the new 13th-generation Intel or AMD Ryzen-based boards the company announced today. Framework is now looking to build on that track record with an all-new Framework Laptop 16. It's a larger-screened model that can fit more powerful processors, dedicated GPUs, and a range of different keyboard modules, all with the same commitment to repairability and upgradeability seen in the original Framework Laptop (now retroactively dubbed the Framework Laptop 13).

Framework isn't discussing many details yet; preorders won't open until "this spring," and shipments won't begin until "late 2023." Today, the company provided a preview of the laptop's features, along with developer documentation to encourage the creation of new Input Modules -- components that allow for keyboard customization much like the current Expansion Card system allows for port customization.

The European Commission has adopted a new set of right to repair rules (PDF) that, among other things, will add electronic devices like smartphones and tablets to a list of goods that must be built with repairability in mind. The Register reports: The new rules will need to be need to be negotiated between the European Parliament and member states before they can be turned into law. If they are, a lot more than just repairability requirements will change. One provision will require companies selling consumer goods in the EU to offer repairs (as opposed to just replacing a damaged device) free of charge within a legal guarantee period unless it would be cheaper to replace a damaged item. Beyond that, the directive also adds a set of rights for device repairability outside of legal guarantee periods that the EC said will help make repair a better option than simply tossing a damaged product away.

Under the new post-guarantee period rule, companies that produce goods the EU defines as subject to repairability requirements (eg, appliances, commercial computer hardware, and soon cellphones and tablets) are obliged to repair such items for five to 10 years after purchase if a customer demands so, and the repair is possible. OEMs will also need to inform consumers about which products they are liable to repair, and consumers will be able to request a new Repair Information Form from anyone doing a repair that makes pricing and fees more transparent. The post-guarantee period repair rule also establishes the creation of an online "repair matchmaking platform" for EU consumers, and calls for the creation of a European repair standard that will "help consumers identify repairers who commit to a higher quality."

"Repair is key to ending the model of 'take, make, break, and throw away' that is so harmful to our planet, our health and our economy," said Frans Timmermans, EVP for the European Green Deal, which aims to make the whole of EU carbon neutral by 2050. On that note, the EC proposed a set of anti-greenwashing laws alongside passing its right to repair rule yesterday that would make it illegal to make any green claims about a product without evidence. Citing the fact that 94 percent of Europeans believe protecting the environment is important, the EC said its proposal covers any explicit, voluntarily-made claims "which relate to the environmental impact, aspect, or performance of a product or the trader itself." Any such claims, like a laptop being made from recycled plastic, would need to be independently verified and proven with scientific evidence, the EC said.

sciencehabit shares a report from Science Magazine: Researchers have designed a robot that can create and cook a cake with up to seven ingredients, more than any other printed food to date. The scientists built their programmable patisserie by retrofitting a 3D printer with nozzles designed to squeeze out selected ingredients. They then programmed it to dispense those into layered cakes. Initial trials resulted in triangular gobs of sweet goo, so the researchers came up with a winning recipe that could hold its own. They nested softer ingredients, such as jelly and banana puree, inside of stiffer ingredients, such as peanut butter and Nutella, then reinforced those with hefty doses of graham cracker crust. Then, they broiled the crust with a laser and topped the cake with frosting and cherry glaze. The result? A cheesecake, of sorts.

Despite its novelty, the computer-guided cook may not be able to battle it out under the stern eye of a guest judge any time soon -- each slice took about 30 minutes to print. Further in the future, however, better printers could make some cooking automatic, freeing people from kitchen tasks they may find tiring or repetitive -- assuming you don't enjoy those things. A food printer could also be programmed to dispense meals with precision-controlled nutrient and calorie content, helping prepare food for those on strict diets. The study has been published in the journal npj Science of Food.

By the end of 2022, global renewable generation capacity amounted to 3,372 gigawatts (GW), growing the stock of renewable power by 295 GW or 9.6%, according to the International Renewable Energy Agency (IRENA). Renewables produced an overwhelming 83% of all power capacity added last year. Electrek reports: Renewable Capacity Statistics 2023, released today by IRENA, shows that renewable energy continues to grow at record levels despite global uncertainties, confirming the downward trend of fossil fuels. While many countries increased their renewable capacity in 2022, the significant growth of renewables is concentrated in Asia, the US, and Europe. IRENA reports that almost half of all new capacity in 2022 was added in Asia, resulting in a total of 1.63 terawatts (TW) of renewable capacity by 2022. China was the largest contributor, adding 141 GW to Asia's new capacity.

Renewables in Europe and North America grew by 57.3 GW and 29.1 GW, respectively. Africa saw an increase of 2.7 GW, slightly above 2021. Oceania continued its double-digit growth with an expansion of 5.2 GW, and South America had a capacity expansion of 18.2 GW. The Middle East recorded its highest increase in renewables on record, with 3.2 GW of new capacity added in 2022, an increase of 12.8%. Although hydropower accounted for the largest share of the global total renewable generation capacity with 1,250 GW, solar and wind continued to dominate new generating capacity. Together, both technologies contributed 90% to the share of all new renewable capacity in 2022. Solar led with a 22% (191 GW) increase, followed by wind, which increased its generating capacity by 9% (75 GW).

An anonymous reader quotes a report from Bloomberg: Last Energy Inc., a startup developing advanced, smaller nuclear power plants, completed four deals worth $18.9 billion to build 34 reactors in Europe. The Washington-based company expects to install the first of its 20-megawatt systems as soon as 2025, Chief Executive Officer Bret Kugelmass said in an interview Monday. Last is building its first system in Texas, but is still seeking approval from regulators in Poland and the UK, where it closed the Europe deals.

Last is part of a wave of companies seeking to install smaller reactors that could be manufactured in factories and assembled on-site. The approach is expected to make them faster and cheaper to build than conventional nuclear plants, but the technology is still untested. Kugelmass said the agreements validate the strategy and show growing demand for nuclear energy. "It's huge for us, and it's a milestone for the whole industry," he said.

Last plans to build and operate the plants, and the $18.9 billion value of the deals represents the revenue it anticipates over the course of power-purchase agreements that stretch as long as 24 years. The company must arrange financing for the estimated $100 million it will need for each system. The customers include a data-center operator and a hydrogen producer in the UK and an industrial zone in Poland. It announced last year agreements to build 12 systems for two additional customers in Poland. While the lack of regulatory approval is a key barrier, Last Energy's small design means that engineering and safety issues will be simpler than with larger reactors, said Jessica Lovering, executive director of Good Energy Collective, a pro-nuclear research group.

An anonymous reader quotes a report from Ars Technica: An analysis of 2,007 damaged or defective hard disk drives (HDDs) has led a data recovery firm to conclude that "in general, old drives seem more durable and resilient than new drives." The statement comes from a Los Angeles-headquartered HDD, SSD, and RAID data recovery firm aptly named Secure Data Recovery that has been in business since 2007 and claims to have resolved more than 100,000 cases. It studied the HDDs it received in 2022. "Most" of those drives were 40GB to 10TB, according to a blog post by Secure Data Recovery spotted by Blocks & Files on Thursday.

Secure Data Recovery's March 8 post broke down the HDDs it received by engineer-verified "power-on hours," or the total amount of time the drive was functional, starting from when its owner began using it and ending when the device arrived at Secure Data Recovery. The firm also determined the drives' current pending sector count, depicting "the number of damaged or unusable sectors the hard drive developed during routine read-and-write operations." The company's data doesn't include HDDs that endured non-predictable failures or damage by unexpected events, such as electrical surges, malware, natural disasters, and "accidental mishandling," the company said.

Among the sample, 936 drives are from Western Digital, 559 come from Seagate, 211 are Hitachi brand, 151 are Toshiba's, 123 are Samsung's, and there are 27 Maxtor drives. Notably, 74.5 percent of the HDDs came from either Western Digital or Seagate, which Secure Data Recovery noted accounted for 80 percent of hard drive shipments in 2021, citing Digital Storage Technology Newsletter data shared by Forbes. The average time before failure among the sample size was 2 years and 10 months, and the 2,007 defective HDDs had an average of 1,548 bad sectors. "While 1,548 bad sectors out of hundreds of millions or even billions of disk subdivisions might seem minuscule, the rate of development often increases, and the risk of data corruption multiplies," the blog said. "We found that the five most durable and resilient hard drives from each manufacturer were made before 2015," says Secure Data Recovery. "On the other hand, most of the least durable and resilient hard drives from each manufacturer were made after 2015." One of the reasons for this may have to do with HDD manufacturers "pushing the performance envelope," adds Ars. "This includes size limits that cut 'allowance between moving parts, appearing to affect mechanical damage and wear resistance.'"

Secure Data Recovery also believes that shingled magnetic recording (SMR) impacts HDD reliability, as the disks place components under "more stress."

"What this study shows is not the average working life of a hard disk drive," notes Blacks & Files. "Instead it provides the average working life if a failed disk drive. Cloud storage provider Backblaze issues statistics about the working life of its disk drive fleet and its numbers are quite different." A recent report of theirs found that SSDs are more reliable than HDDs.

Computer component maker Acer built a lightweight electric bike called the Acer ebii. Electrek reports: This lightweight 35 lb. (16 kg) e-bike features a number of gadgets and gizmos we have yet to spot in the industry, such as built-in AI designed to predictively control the transmission and make use of collision detection sensors for a safer ride. There's also proximity unlocking feature that the company says "automatically locks your bike when you leave and unlocks it again when you're nearby." My Gogoro electric scooter has a similar function, though that's a highway-capable vehicle.

Tracking capabilities are built into the ebii to help keep tabs on it 24/7. If the bike is ever stolen, it can be locked remotely and tracked using its built-in GPS locator. But don't think that you won't find typical bike parts here either, as the Acer ebii still features high-end components like a belt drive instead of a chain drive, 160mm hydraulic disc brakes, and 360-degree LED lighting. Airless tires are designed to remove the chance of flats, and a lefty-style fork does double duty as a conversation piece and a fancy weight saver.

There's also a 460 Wh electric bicycle battery that is said to offer a range of up to 68 miles (110 km) per charge. A top speed of 15 mph (25 km/h) and a 250W rear hub motor look to keep the bike within European and Asian power and speed limits. There's no hand throttle, which means riders will have to rely on pedal assist that is activated when the rider spins the pedals. It appears that there's some confusion about the 2.5-hour charger included with the bike, as some in the industry seem to think it can be used to charge phones and batteries as well. In fact, it's actually the e-bike's removable battery itself that can function as a portable power station to charge up your mobile devices. Pricing and availability are not yet available. But there is a launch video to build up excitement.

In a blog post shared last week, Ingka, the legal entity responsible for most of Ikea's stores, says it now has a total of 100 autonomous drones counting stock in its warehouses during nonoperational hours. The Verge reports: Ikea first partnered with the drone-making company Verity in 2020 to deploy the drones in Switzerland, but now, the company says they're zipping around 16 locations across Belgium, Croatia, Slovenia, Germany, Italy, and the Netherlands. The Swedish furniture giant says the drones help improve the accuracy of product availability and also support "a more ergonomic workplace," as it saves employees from counting stock manually.

Verity, which specializes in creating self-flying drones for warehouses and even concerts, was founded by Raffaello D'Andrea, one of the creators of Kiva Systems, or what's now called Amazon Robotics. As noted by D'Andrea in 2020, the drones work by taking off from a charging station and then going to each pallet in the warehouse to capture images, videos, and 3D depth scans of the items. Once the job is done, the drones return to their charging stations to download the collected data. The drones not only count inventory but also help employees determine if something's missing or in the wrong spot.

After almost 17 years online, file-hosting veteran Zippyshare will shut down at the end of the month. TorrentFreak: Founded in 2006, Zippyshare was known for its free, no-nonsense, no-frills approach to storing files online. Having changed very little over the years, Zippyshare's operators say the platform is now a dinosaur that costs too much to run in a world where ad-blocking is widespread. Zippyshare said, "Since 2006 we have been on the market in an unchanged form, that is, as ad financed/free file hosting. However, you have been visiting in less and less over the years, as the arguably very simple formula of the services we offer is slowly running out of steam. I guess all the competing file storage service companies on the market look better, offer better performance and more features. No one needs a dinosaur like us anymore."

An anonymous reader shares this report from Phoronix: For over a half-decade ASUS has been selling the Tinker Board devices as their line of Raspberry Pi alternatives. To date the ASUS Tinker Board single board computers have all been Arm-based while now they have launched their first RISC-V board, the Tinker V.

The ASUS Tinker V is their first RISC-V single board computer and intended for the industrial IoT (Internet of Things) developer community. The ASUS Tinker V is set to officially run Debian Linux and Yocto while surely with time more Linux distributions will be supported.... Being IoT focused, there isn't any display support. Those interested in learning more about the ASUS Tinker V can do so via tinker-board.asus.com.
The Register notes that Asus "is offering at least five years of support for Tinker V... Dedicated on-site technical support is also available to shorten customer development cycles and accelerate application deployment." The move shows that the RISC-V open-source instruction set architecture continues to garner support. The last RISC-V Summit in San Jose saw the launch of a family of datacenter-class processors based on the architecture from Ventana Micro Systems, while XMOS unveiled new high-performance microcontrollers using RISC-V.

According to Asus, Tinker V samples will be available in Q2 of this year, but it did not disclose a date for full availability or pricing.

Slashdot reader Prahjister knows what a system on a chip is. But that's part of the problem: I recently started hearing the term SoC at work when referring to digital signage hardware. This has really triggered me.... It is like when I heard people refer to a PC as a CPU.

I tried to speak to my colleagues and dissuade them from using this term in this manner with no luck. Am I wrong trying to dissuade them for this?
Maybe another question would be: Are there technical malapropisms that drive you crazy? Share your own thoughts and experiences in the comments.

And when should you call hardware a 'SoC'?

"Minnesota regulators said Thursday they're monitoring the cleanup of a leak of 400,000 gallons of radioactive water from Xcel Energy's Monticello nuclear power plant," reports the Associated Press, "and the company said there's no danger to the public." "Xcel Energy took swift action to contain the leak to the plant site, which poses no health and safety risk to the local community or the environment," the Minneapolis-based utility said in a statement. While Xcel reported the leak of water containing tritium to state and federal authorities in late November, the spill had not been made public before Thursday.

State officials said they waited to get more information before going public with it.... "Now that we have all the information about where the leak occurred, how much was released into groundwater, and that contaminated groundwater had moved beyond the original location, we are sharing this information," said Minnesota Pollution Control Agency spokesman Michael Rafferty, adding the water remains contained on Xcel's property and poses no immediate public health risk.

The company said it notified the federal Nuclear Regulatory Commission and the state on Nov. 22, the day after it confirmed the leak, which came from a pipe between two buildings. Since then, it has been pumping groundwater, storing and processing the contaminated water, which contains tritium levels below federal thresholds. "Ongoing monitoring from over two dozen on-site monitoring wells confirms that the leaked water is fully contained on-site and has not been detected beyond the facility or in any local drinking water," the Xcel Energy statement said.

When asked why Xcel Energy didn't notify the public earlier, the company said: "We understand the importance of quickly informing the communities we serve if a situation poses an immediate threat to health and safety. In this case, there was no such threat."

The UK Space Agency said Friday it would back research by Rolls-Royce looking at the use of nuclear power on the moon. CNBC reports: In a statement, the government agency said researchers from Rolls-Royce had been working on a Micro-Reactor program "to develop technology that will provide power needed for humans to live and work on the Moon." The UKSA will now provide [around $3.52 million] of funding for the project, which it said would "deliver an initial demonstration of a UK lunar modular nuclear reactor."

Rolls-Royce is set to work with a range of organizations on the project, including the University of Sheffield's Advanced Manufacturing Research Centre and Nuclear AMRC, and the University of Oxford. "Developing space nuclear power offers a unique chance to support innovative technologies and grow our nuclear, science and space engineering skills base," Paul Bate, chief executive of the UK Space Agency, said. Bate added that Rolls-Royce's research "could lay the groundwork for powering continuous human presence on the Moon, while enhancing the wider UK space sector, creating jobs and generating further investment." According to the UKSA, Rolls-Royce [...] is aiming "to have a reactor ready to send to the Moon by 2029."
