It is an essential weapon in the fight against climate change
Natrium's advanced nuclear reactor design, which will be up and running as a full scale trial plant in the late 2020s, also stores several times more energy than most grid scale batteries for rapid load response. //
Natrium's demonstration plant will be fully operational and connected to the power grid in its as-yet-unknown location by the mid to late 2020s. Its fast-neutron reactor will use high-temperature liquid sodium as its reactor coolant instead of water.
One of sodium's key advantages is the huge 785-degree temperature range between its solid and gaseous states; water offers only a 100-Kelvin range, so it needs to be pressurized in order to handle higher amounts of heat energy. High levels of pressure can have explosive consequences, and they also greatly increase the cost of the plant, as nuclear-grade high pressure components are not cheap. //
Liquid sodium will transfer an impressive amount of heat away from the reactor at normal atmospheric pressures, with the added bonus that it won't dissociate into hydrogen and oxygen, so Fukushima-style hydrogen explosions are out of the question. It's also non-corrosive, sidestepping an issue that puts a question mark over molten salt reactors.
Like many of the next-generation nuclear reactors under development, the Natrium design will use High-Assay, Low Enriched Uranium (HALEU) as its nuclear fuel. Where natural uranium comes out of the ground containing around 0.7 percent of the U-235 isotope that's split to generate nuclear energy, and traditional Low Enriched Uranium (LEU) nuclear reactor fuel is enriched by centrifugal processes or gas diffusion to contain 3-5 percent U-235, HALEU is further enriched, between 5 and 20 percent. For comparison, nuclear weapons need uranium enriched to more than 90 percent.
HALEU fuel can be produced by reprocessing the spent fuel from traditional nuclear power plants, and its higher grade improves reactor performance and efficiency to the point where it allows advanced reactors to be much smaller than LEU plants. Natrium says it should be four times more fuel efficient than light water reactors. //
The molten salt thermal energy storage attached to the Natrium generator holds ten times as much on-demand energy as the biggest grid-scale battery projects on the planet.
We develop Generation IV high-temp gas cooled nuclear reactors & the TRISO-X fuel to power them.
We are designing the safest, most efficient and most advanced small modular reactors for a wide range of global markets & applications.
We use TRISO particle fuel. We manufacture our own proprietary version (TRISO-X) to ensure supply & quality control.
Xe-100 is a 80 MWe reactor that can be scaled into a ‘four-pack’ 320 MWe power plant—with our modular design, the scale can grow even larger as needed.
Toyota is selling the Mirai fuel cell vehicle running on hydrogen, and plans to boost tenfold the global sales of the Mirai with the second-generation Mirai.
The new Toyota Mirai will have a 30% increase in driving range to around 650 kilometers (404 miles), the carmaker said at the end of November. //
The average price for hydrogen fuel in California is about US$16/kg — gasoline is sold by the gallon (volume) and hydrogen by the kilogram (weight).
To put that in perspective, 1 gallon of gasoline has about the same amount of energy as 1 kg of hydrogen.

I appreciate Senator Ted Cruz’s effort – and his many other efforts – but his bill ending endless Congressional terms isn’t a solution.
I am loathe to question Senator Cruz on Constitutional questions – but his bill raises Constitutional questions. We had to amend the Constitution to term-limit presidents. I would imagine we’d need to do the same thing to do the same thing to Congressmen.
And it almost certainly isn’t a practical solution. How many members of Congress will vote to limit their time as members of Congress?
Meanwhile, term limits just turn more elected officials more rapidly into more lobbyists.
And term limits accidentally, massively over-empower residual Hill staffers – who aren’t elected and aren’t term limited.
All of which is demonstrably worse than what we have now.
To solve the problems – we must address the actual problems. Implementing term limits doesn’t do that.
In the House – that means ending gerrymandering. For the Senate – we must repeal the Seventeenth Amendment.
In the House:
Gerrymandering?:
“(A) practice intended to establish an unfair political advantage for a particular party or group by manipulating district boundaries….
“Two principal tactics are used in gerrymandering.
“‘Cracking’ (i.e. diluting the voting power of the opposing party’s supporters across many districts).
“And ‘packing’ (concentrating the opposing party’s voting power in one district to reduce their voting power in other districts).”
Gerrymandering is government officials choosing us – rather than us choosing them. //
Term limits replace old Nancy Pelosis with…young Nancy Pelosis. Because 80+% of Congressional districts are gerrymandered to an overwhelming Democrat or Republican advantage. //
In the Senate:
Seventeenth Amendment?:
“(E)stablished the direct election of United States senators in each state. The amendment supersedes Article I, §3, Clauses 1 and 2 of the Constitution, under which senators were elected by state legislatures.”
We must return to the pre-Seventeenth Amendment status quo. Because it served as a massive check on federal spending – and myriad other overreaches. //
Term limits is a top-down, DC-centered “fix” – to problems caused by top-down, DC-centered “fixes.” That actually fixes nothing. And actually makes things worse.
The real solution is to fix the actual, original problems.
End gerrymandering – and repeal the Seventeenth Amendment.
And restore the proper accountability, roles and responsibilities of government at every level.
It could mean a "negative" leap second.
Even time did not escape 2020 unscathed.
The 28 fastest days on record (since 1960) all occurred in 2020, with Earth completing its revolutions around its axis milliseconds quicker than average. That's not particularly alarming — the planet's rotation varies slightly all the time, driven by variations in atmospheric pressure, winds, ocean currents and the movement of the core. But it is inconvenient for international timekeepers, who use ultra-accurate atomic clocks to meter out the Coordinated Universal Time (UTC) by which everyone sets their clocks. When astronomical time, set by the time it takes the Earth to make one full rotation, deviates from UTC by more than 0.4 seconds, UTC gets an adjustment.
A newly found inscription has forced archaeologists to rethink their dating of a fortification wall, and high-tech analysis is building a clearer picture than ever of the site //
With the fortress’s iconic round tower jutting into the sky behind us, Re’em recounted a thrilling discovery of a dated inscription located in secondary use, meaning it had been recycled from some earlier use, in the foundations of an outer western wall.
“We all thought that this was from the time of the Crusaders, the 12th century. It appears in the books! But now, when we conducted this excavation, we have a large question mark. Because right here we uncovered an Arabic inscription in secondary use that belonged to one of the great Ayyubid rulers of Jerusalem, his name is El-Melek El-Muatem Isa,” said Re’em.
Jerusalem was conquered by the Crusaders in 1099 and retaken by a Muslim dynasty, the Ayyubids, in 1187. By 1212, the city was ruled by the nephew of Saladin, El-Melek El-Muatem Isa, also commonly known in English as Al-Mu’azzam Isa.
According to Re’em, Al-Mu’azzam Isa erected the fortifications of Jerusalem in approximately 1212, “and on every tower he put a large sign in Arabic, ‘I’m the great ruler El-Melek El-Muatem Isa.'” Alongside his name on this stone was the year, 1212.
Rarely do archaeologists hit the jackpot of a securely dated inscription. This one, explained Re’em, also sheds light on the mindset of the Muslim ruler as he faced down encroaching Crusader forces, who moved toward the city in 1217.
Re’em said that as the Crusaders made their way to the Holy Land, the sultan did not have a standing army available in Jerusalem, so he decided to tear down the city’s fortifications, thinking it would be easier to retake that way after the Crusaders presumably entered the city.
“So he demolished all his walls and those inscriptions,” said Re’em, “but the Crusaders never came to Jerusalem.”
Eventually, the walls were rebuilt, and the stone with his name and date was used in the foundation of the walls of the western fortification of the citadel. There it would sit for centuries until being found by Re’em and his team, helping rewrite what we know about the citadel.
Congressman and Wounded Vet Dan Crenshaw has always riled up conservatives.

I welcomed Google’s friendly advice for a few days, but after a while, I would be caught entirely off guard by it. When focusing deeply on a task in complete silence, my Hub would abruptly shout at me and scare the crap out of me, causing my heart to skip a beat. Not only did it break my peace, but it caused me to lose my train of thought as well. When this happens several times a day and every single day for weeks, you realize that it’s more of a nuisance than a help, I promise. //
The worst part is that since the feature is called ‘Workday Reminders’, and since Google Assistant has about a gazillion settings packed into one wall of text, I kept searching for the settings to disable them in various places other than Routines. I checked Reminders (because duh), I checked my Nest Hub settings, and so on all to no avail. After a few weeks of torture, and having only attained peace by unplugging my Assistant devices, I finally located the Workday ‘routine’ blandly mixed in with the other routines. No longer did it feature the colorful icon it had when I set them up – instead, it was a simple blue outlined icon mixed in with the rest. It was completely indistinguishable. I really am beginning to see what people are saying about Google’s design becoming less attention-grabbing and more ‘same-y’.
KiwiSDR is hardware that uses a software-defined radio to monitor transmissions in a local area and stream them over the Internet. A largely hobbyist base of users does all kinds of cool things with the playing-card-sized devices. For instance, a user in Manhattan could connect one to the Internet so that people in Madrid, Spain, or Sydney, Australia, could listen to AM radio broadcasts, CB radio conversations, or even watch lightning storms in Manhattan.
On Wednesday, users learned that for years, their devices had been equipped with a backdoor that allowed the KiwiSDR creator—and possibly others—to log in to the devices with administrative system rights. The remote admin could then make configuration changes and access data not just for the KiwiSDR but in many cases to the Raspberry Pi, BeagleBone Black, or other computing devices the SDR hardware is connected to.
As demand for energy rises in the developing world, nuclear power could provide one partial solution to the global climate crisis. Large countries such as Russia and China are both investing in nuclear power and positioning themselves to export technology and expertise. But whether developing countries should incorporate nuclear energy depends on a range of factors such as local energy demand and the availability of other energy sources. They should also consider how competitive nuclear energy would be. Most important, countries that go nuclear should have sufficient technological, industrial, and political stability. //
Nuclear expansion in Africa. Energy demand in sub-Saharan Africa is projected to grow by 80 per cent by 2040—that is, at 3.5 percent a year—faster than the global average of 1.3 percent. Ghana, Kenya, and Namibia have expressed interest in nuclear power. Russia is at various stages of negotiating nuclear cooperation agreements with at least 16 African countries. Currently, only South Africa has a functioning nuclear power plant. However, several African countries possess substantial uranium ore deposits. Namibia, for example, has seven percent of the world’s known uranium reserves and has made a political commitment to supplying its own energy from nuclear power in the future. Still, African access to electricity is the lowest in the world, according to the World Bank, and infrastructure in many parts of the continent is scarce. Consequently, large investments and development are needed before technologically demanding nuclear power production will be economically viable. //
decisions regarding nuclear power often result not from common-sense considerations, but rather from bargaining between countries that seek nuclear technologies and countries that can help them master such technologies. Developing countries rely on the IAEA and major powers such as the United States and Russia to provide access to the purposeful and peaceful application of the nuclear energy worldwide.
This situation of dependency creates challenges and opportunities for the IAEA and major powers engaged in providing access to the technology and expertise necessary for nuclear energy production. The challenge is linked to upholding the commitment to provide access to peaceful nuclear use while also detecting the potential diversion of nuclear technologies for non-peaceful purposes. Balancing these commitments should entail preventing the expansion of nuclear power in regions that are unstable and prone to proliferation. The Middle East is currently the most combustible region in this respect, with several ongoing conflicts involving rival states with nuclear ambitions. Limiting or strictly controlling access to nuclear technology may be one way of controlling developments. On the other hand, nuclear states and the IAEA have an opportunity to provide accessible power to regions that are more stable and whose population density make them suitable for nuclear power. If solutions to produce more cost-efficient nuclear power can be found, this will provide one opportunity to solve the dual problem of the growing global demand for energy and global climate change—an opportunity that should not be missed.
Sorbom has his doctorate from MIT and is co-founder and chief scientific officer of Commonwealth Fusion Systems, a rapidly growing company spun out of Sorbom and his co-founders' research. CFS aims to commercialize fusion, a safe and virtually limitless source of "clean energy," to combat climate change. The company is funded by the likes of Jeff Bezos and Bill Gates by way of energy innovation investment fund Breakthrough Energy. //
Creating and capturing the energy of the sun is delicate. A special form of hydrogen has to be heated until it gets to the fourth state of matter, plasma.
"If you heat a solid up, it turns into a liquid. If you heat that liquid up, it turns into a gas. If you heat that gas up, it turns into a plasma," he says, and "you get a charge soup of particles."
Plasma is an extremely fragile state of matter. If interrupted, the fusion reaction stops. So scientists developed a machine known by the Russian acronym tokamak, which uses magnetic fields to hold a doughnut of plasma safely in a container.

#DidYouKnow that the word "#tokamak" stands for "ТОроидальная КАмера с МАгнитными Катушками" (TOroidal'naya KAmera s MAgnitnymi Katushkami) - "toroidal camera with manetic coil" in english? #DYK #FusionEnergy @iterorg //
Research by Sorbom and his colleagues focuses on improving the tokamak, specifically by "making better and better magnets," Sorbom says.
Better and stronger magnets mean better insulation for the plasma, and the more efficiently the plasma can be heated up, the more energy that can be generated, eventually producing net energy. In the machines CFS is working on, temperatures will be around 100 million degrees Celsius, which is roughly 180 million degrees Fahrenheit.
If you read ebooks a lot, you may have noticed that EPUB is the most widely adopted ebook format. Almost all mainstream eReaders, computer operating systems or ebook reader apps support this format except some Kindle devices (If you have epub books that you want to read on your Kindle, you can send epub to Kindle). In this article, I will share with you the best 10 free epub readers for Android smartphones or tablets to help you read epub ebooks on the screen with the most pleasant reading experience.
Outdoor models AOU18RLXFZH, AOU24RLXFZH and AOU36RLXFH allow you to connect 2 to 5 indoor units, depending on the outdoor unit selected. These systems provide both heating and cooling for year-round comfort. //
The Inverter component allows the outdoor unit to vary its speed and output to match the required capacity of the indoor unit. Thus, the Inverter model can achieve 30% more operating efficiency than conventional models and therefore, is much less expensive to run. //
The XLTH outdoor units are engineered to operate in temperatures down to -15°F, lower than any other mini-split available today. These outdoor units also include base drainage holes, a large heat exchanger, and a high capacity compressor.
Here are seven key moments that occurred before and after lawmakers were forced to suspend their debate of evidence of voter fraud and other election irregularities and shelter in place. //
- Cruz Offers ‘Door Number 3’
Also before the rioters breached the Capitol, Cruz made the case for naming an Electoral Commission as a “credible, impartial body to hear the evidence” as part of an emergency 10-day audit of six disputed states. //
After the 1876 presidential election, Congress appointed an Electoral Commission to decide the dispute between Republican Rutherford B. Hayes and Democrat Samuel Tilden.
The panel was made up of five House members, five senators, and five Supreme Court justices. The commission decided four disputed states–South Carolina, Florida, Louisiana, and Oregon–in favor of Hayes.
Until Sen. Mike Lee, R-Utah, recently stood up as the voice of reason, and blocked a museum dedicated to those Americans the government hives off as “Hispanic” or “Latino,” it looked like conservatives had learned all the wrong lessons from their recent success with those voters.
“I understand what my colleagues are trying to do and why. I respect what they’re trying to do. I even share their interests in ensuring that these stories are told. But the last thing we need is to further divide an already divided nation with an array of segregated, separate-but-equal museums for hyphenated identity groups,” said Lee in a statement from the Senate floor about the Smithsonian Institution museum that up to that point seemed all but a fait accompli, having gathered bipartisan support.
“At this moment in the history of our diverse nation, we need our federal government and the Smithsonian Institution itself to pull us closer together and not further apart,” the Utah Republican went on.
The Smithsonian, a taxpayer-funded institution, “should not have an exclusive museum of American Latino history or a museum of women’s history or museum of American men’s history or Mormon history or Asian American history or Catholic history. American history is an inclusive story that should unite us.”
The best method for electing the president of the United States, debated by the Founding Fathers, is a bone of contention generations later. Today, many call the Electoral College outdated. But Carly Terry, a new high school graduate from Nassau County, Florida, argued in an award-winning essay that the Founders settled on the Electoral College for a reason, and it remains the best way to elect the president.
Terry was awarded a $10,000 scholarship from the U.S. Constitution Scholarship Foundation for her essay as a senior in defense of the Electoral College. She and Howard Pines, a founder of the organization, join the podcast to discuss precisely why we shouldn’t abandon the Electoral College.
How do we know Google knows they stole Android from Oracle-Java?
The E-Mail That Google Really Doesn’t Want A Jury To See:
“Lawyers defending Google against a patent and copyright lawsuit brought by Oracle are trying desperately to keep a particular engineer’s e-mail out of the public eye-but it looks like they’re unlikely to succeed.
“The e-mail, from Google engineer Tim Lindholm to the head of Google’s Android division, Andy Rubin, recommends that Google negotiate for a license to Java rather than pick an alternative system….
“The second paragraph of the email reads:
“‘What we’ve actually been asked to do by Larry [Page] and Sergey [Brin] (Google’s founders) is to investigate what technical alternatives exist to Java for Android and Chrome.
“We’ve been over a bunch of these and think they all suck. We conclude that we need to negotiate a license for Java under the terms we need.’”
Except Google never did negotiate for Android “a license for Java under the terms we need.”
But they released Android anyway.
That’s not legal.
“At least 36 batches of mail-in ballots from the November election were double counted in Fulton County. That’s a total of more than 4000 votes. Those numbers come from a group called VoterGA, which along with Bob Cheeley sued to get them. The final tally from the double counts we know about amounts to more than 3300 votes for Joe Biden and 865 votes for Donald Trump,” Carlson said. //
Voter GA had tried to get the audit tally sheets but Fulton County wouldn’t release more than 100,000 of them initially. But Voter GA finally got some of them. They said that they found 7 audit tally sheets that were falsified. For example, a batch containing 59 ballot images for Joe Biden and 42 for Donald Trump was reported as 100 for Joe Biden and zero for Trump. The seven batches of ballot images had 705 votes — 554 for Biden, 140 for Trump, and 11 for Jorgensen. However, the tally sheets showed a higher vote total and had 100 percent of the votes going to Biden – 850 for Biden, 0 for Trump, and 0 for Jorgensen. The Atlanta Journal-Constitution doesn’t address that tally sheet problem in their article on the matter.
Carlson notes other issues but makes the greater point that the way to quell concerns is to address the questions, not to shut them down.
This year’s controversial documentary ‘Planet of the Humans,’ produced by Michael Moore, posed some uncomfortable questions to renewable energy enthusiasts. While the film has serious flaws, it gets one big thing right: renewables are not a magic fix-all for our energy problems.
It all comes down to what we mean by ‘renewable’. People tend to think that an energy type is renewable…
Where “doing everything” involves making investments that are slower or less cost effective, which divert resources away from preferable options, or which in some other way impede them, the result would be potentially disastrous for carbon emissions mitigation.
Amidst many uncertainties, the real questions we should be addressing are about which investments offer the most cost-effective and beneficial ways forward.
Our new paper, Differences in carbon emissions reduction between countries pursuing renewable electricity versus nuclear power, seeks to contribute towards this debate.
https://www.nature.com/articles/s41560-020-00696-3 //
Our research explores this dilemma retrospectively, examining past patterns in the attachments (i.e. investments) of different countries to nuclear or renewable strategies. Our paper addresses three hypotheses:
A “nuclear climate mitigation” hypothesis: that countries with a greater attachment to nuclear power will tend to have lower overall carbon emissions.
A “renewables climate mitigation” hypothesis: that countries with a greater attachment to renewables will tend to have lower overall carbon emissions.
A “crowding out” hypothesis: that countries with a greater attachment to nuclear will tend to have a lesser attachment to renewables, and vice versa.
Across the study countries as a whole we found that the “nuclear climate mitigation” hypothesis is not sustained by the evidence at an appropriate level of statistical significance. The renewable climate mitigation hypothesis is confirmed with substantial significance. And the crowding out hypothesis is also significantly sustained.
Put plainly – if countries want to lower emissions as substantially, rapidly and cost-effectively as possible, they should prioritise support for renewables rather than nuclear power. Pursuit of nuclear strategies risks taking up resources that could be used more effectively and suppressing the uptake of renewable energy.
Argonne scientists look to 3D printing to ease separation anxiety, which paves the way to recycle more nuclear material. //
We can recycle waste from nuclear reactors in several ways, including one method developed by Argonne scientists in the 1970s. With these approaches, nuclear engineers can recycle 95 percent of the spent nuclear fuel from a reactor, leaving only five percent to be stored as long-term waste. But now, for the first time, Argonne scientists have printed 3-D parts that pave the way to recycling even more nuclear waste, as detailed in a Sept. 6 article in Scientific Reports.
At first glance, recycling another two percent of nuclear waste may not sound like much. But it would dramatically reduce both the amount of waste stored and the time it remains hazardous.
“Rather than store five percent for hundreds of thousands of years, the remaining three percent needs to be stored at a maximum of about one thousand years,” said Andrew Breshears, an Argonne nuclear chemist and co-author. “In other words, this additional step may reduce the length of storage almost one thousandfold.” And breaking down that nuclear material in a fourth generation fast reactor would generate additional electricity.
In the modern world, countries need a reliable electricity grid to prosper. Globally, demand for electricity is growing as a result of population growth, new ways to use electricity, and the effort to spread access to electrical power to a greater portion of the world’s population.
For the past four years, Robert Bryce has been intensively studying the electricity business, which he describes as the world’s second largest industry by revenue, trailing only the fossil fuel industry. He calculates that global annual electricity sales total approximately $2 trillion. He traveled to a number of different locations to learn how countries, states, cities and even individual businesses are creating, transmitting and using electricity.
His resulting book, A Question of Power: Electricity and the Wealth of Nations, was released on March 10, 2020. By the time it had been released, the world was in the throes of responding to the coronavirus and his well-planned book tour had been essentially cancelled.
One of the first acts of the new Biden Administration is cancelling the permits for the Keystone XL Pipeline, a project of Canadian energy giant TC Energy that would have moved 800,000 barrels per day of heavy crude from Alberta to Cushing, OK, providing easier access to Gulf Coast refineries. The project was originally killed in the Obama Administration due to State Department objections, later to be revived and fast-tracked by President Trump. Cancelling the project, well into its construction, will cost 11,000 union construction jobs, the ongoing pipeline jobs and revenues, and $2 billion of future investment. //
HISTORICAL NOTE: Joe Biden is a long-standing opponent of domestic energy infrastructure. In 1973, a deadlocked Senate nearly blocked the Trans-Alaska Pipeline, sorely needed in reaction to the first OPEC embargo. Biden, then a back-bencher, joined the opposition. Vice-President Spiro Agnew broke the Senate’s tie vote, and the pipeline went in service in 1977. Sixteen billion barrels later, America remains free of OPEC domination, thanks in part to the Trans-Alaska Pipeline. The boon to the economy, foreign policy, and the State of Alaska has been immeasurable.

all of my personal data sits within my main C:\Users folder
Rookie mistake. If you’re seriously going to re-install Windows regularly, or as I’d prefer it, if you’re going to use Windows 10 regularly, do not use your boot drive as User storage. Most purchased PC’s support this now (though not all laptops). I have another disagreement with the article, but I’ll get to that at the end.
Your boot drive should be windows and applications only. A separate physical disk is your User folder, Documents, Media, Games, etc.
This makes backup really easy... //
With the above, it only takes about a half hour to reinstall, configure, and kick off restoring applications and games. I used to do this quite often. Now, it’s really only when I have a significant enough hardware upgrade to warrant it.
So my main disagreement is that you need to reinstall Windows 10 at all. There was a time when applications embedded themselves in system startup, and even a technical Windows user would find their Windows installation slowing down over time. This just doesn’t happen with Windows 10. My current installation dates back to the Windows 7 to Windows 10 upgrade. The IT departments of my last two companies have experienced the same thing across thousands of desktops. The tools built into Windows 10 allow for managing application installs and determining what’s running much better than several years ago. I’ve found that when applications slow Windows down, I can remove them and preformance returns. That wasn’t always possible. There was a time when you needed to know what sysinternals and hijack-this were to keep it all running well.
Wind and solar decommissioning costs are trivial. That’s yet another reason why nuclear is dead, but pretending it’s not.
Smaller, cheaper reactor aims to revive nuclear industry, but design problems raise safety concerns //
Engineers at NuScale Power believe they can revive the moribund U.S. nuclear industry by thinking small. Spun out of Oregon State University in 2007, the company is striving to win approval from the U.S. Nuclear Regulatory Commission (NRC) for the design of a new factory-built, modular fission reactor meant to be smaller, safer, and cheaper than the gigawatt behemoths operating today. But even as that 4-year process culminates, reviewers have unearthed design problems, including one that critics say undermines NuScale’s claim that in an emergency, its small modular reactor (SMR) would shut itself down without operator intervention. //
Normally, convection circulates water—laced with boron to tune the nuclear reaction—through the core of NuScale’s reactor (left). If the reactor overheats, it shuts down and valves release steam into the containment vessel, where it conducts heat to a surrounding pool and condenses (center). The water flows back into the core, keeping it safely submerged (right). But the condensed water can be low in boron, and reviewers worried it could cause the reactor to spring back to life.

They praise the process
When you praise the process (e.g., the kid putting effort into a math assignment), instead of the talent or outcome (e.g., the kid's natural ability to solve math problems quickly), kids are more likely to develop a positive attitude toward future challenges. // -
They never make it a competition
Parents love to compare — we can't help it! And sometimes, we'll even tell our kids that they're better than others ("You scored more goals than all your teammates combined!").
Often, it's done with good intentions. We want them to feel as proud as we do, and to be motivated to do even better the next time ... but for all the wrong reasons.
It's not healthy to be trapped in a vicious cycle of competition. Social comparisons can teach kids to always measure success based on the outcomes of other people. //
The better approach? Encourage them to compare their past efforts with their present efforts, rather than with other people. This gets them into the habit of shifting their goals away from being better than everyone else and toward self-improvement. //
- They use observational language
Instead of saying, "That's so good!", you may want to say, "I love the colors in your painting. Tell me more about why you chose them." (This is what it means to praise the process.)
Another example: Instead of saying, "You looked like a pro riding that bike!," parents of motivated kids might say something like, "You were so careful and focused while riding your bike. Even when you wobbled a bit and almost fell off, you kept going! That was cool to watch." //
Lastly, it's important to create an environment of emotional safety. If your child failed a spelling test, refrain from telling them they should have studied harder. Instead, ask them what they think they can do to improve next time.
Kids need to know that they can come to their parents not just when they've done something well, but also when they are struggling with a specific task or challenge.
