The core damage now unfolding in as many as four Japanese nuclear reactors after Friday's post-quake tsunami doused back-up cooling system generators is already becoming stock material for nuclear nihilists. Once again nuclear's perennial opponents are out in force hoping to use this episode to beat back nuclear power.
Greenpeace USA is asking its supporters to email the president and Congress with the suggested language "It's time to invest in clean, renewable energy. Not risky and dangerous nuclear power." This weekend Reuters reported on green parties in France, Italy, and Germany hurriedly parlaying Japan's reactors into a new ploy to push their respective governments away from nuclear. "We cannot master nature, nature rules us," Germany's Green Party parliamentary leader told the news agency.
After a partial core meltdown at Three Mile Island (TMI) in 1979, the American nuclear industry stalled out, overcome by NIMBY-ism. The country built one more nuclear reactor after TMI. While TMI injured no one, the accident wrought lasting devastation on the country's prospects for energy independence with its perfect storm of an ill-timed disaster movie and a sea of media misinformation. The University of Texas at Austin co-hosted a lecture and panel discussion last week on energy's portrayal in the movies. Michael Webber, a mechanical engineering professor at the university and an expert in energy and environmental policy, summed it up thusly, according to the event's Twitter feed: "The China Syndrome did for nuclear what JAWS did for sharks."
Thanks to TMI, the United States has long lost much of the manufacturing infrastructure to efficiently build new full-scale gigawatt nuclear power plants. There are two plants under construction in Georgia, the first after this needless moratorium, and they are now so expensive that President Obama needed to approve a $8 billion loan guarantee (of an estimated $14 billion construction cost) so that Southern Company could obtain its financing for the huge project.
We shouldn't allow America's re-emerging nuclear industry to be swallowed up by a wave of misinformation following this devastating tsunami.
Nuclear is a key element of plans to minimize the impact of global warming. At 17 tons of carbon dioxide per gigawatt-hour, nuclear energy production actually emits less CO2 than wind (solar has nuclear beat by three tons per gigawatt hour). For reference, coal emits over 1,000 tons and natural gas over 600 tons for the same amount of energy. Facts like these have already swayed many environmentalists into the pro-nuke camp. Al Gore has carefully teetered on the edge of full-on nuclear support for some time now.
Holdouts refer to "safe energy" rather than "green energy" alternatives, aiming to exclude nuclear energy which towers over the green energy landscape as the most reliable source out there. Safe energy is a semantic trick along the lines of "pro-life," similarly implying a false dichotomy. That's because American-led nuclear design upgrades expected to power grids by 2020 change the terms of debate.
Meet the iNuke: small modular reactors chock full of elegant design innovations, built cheaply, operating efficiently, and buried underground for your protection. One of the most promising and practical designs is from Corvallis, Oregon-based NuScale. They've got the safest reactor design the industry has ever seen, one that's drawing a scrum of serious shoppers as the company prepares to file for Nuclear Regulatory Commission approval next year.
"We think we're approaching a breaking point where plants are getting so complex and so large that it's reflected in cost," Dr. Jose Reyes, NuScale's chief technology officer, told the audience at MIT's Energy Conference this month. Dr. Reyes drew intense interest from his rapt audience of MIT students and energy industry players at the conference's panel on small and medium nuclear reactors. He quickly got swarmed as his panel came to an end. I had to catch up with him later.
The Department of Energy funded Dr. Reyes and his Oregon State University team in 2000 as part of the Nuclear Energy Research Initiative. "We were commissioned to come up with a design that was small, compact and could be built easily," he told me, initially in the hope that it could be used in developing nations. The team built a functional model unit at their university lab as proof of concept, and NuScale used that lab while overhauling their plans into a commercially viable option. They ended up with a product that costs one-third of a traditional nuclear plant.
The NuScale mini reactor carries a risk of core damage of once in 100 million years. To put that expanse into some perspective, 100 million years ago, flowers had yet to evolve, and dinosaurs roamed the earth. It was the height of the Cretaceous period. Peer reviewed science will not back me up on my next assertion, but I think I have a fair shot of spontaneously turning into a porpoise about once in 100 million years.
We really shouldn't be awed by this kind of technological development, as unreal as it must seem to Green partiers everywhere. Japan's tsunami-drenched reactors are 40 years old. In the same time, space flight has evolved from impractical government-sponsored rockets and shuttles to the dawn of Virgin Galactic. Nuclear just slimmed down too.
In this case, about 70 percent of NuScale's reactor design is similar to the most recent iterations of water-cooled enriched uranium reactors that are common worldwide and share a lineage to those in Japan. But a lot of mutation can occur with a 30 percent DNA swap out, and in NuScale's case, all of it points to safer operating conditions.
For one thing, rather than the huge gigawatt reactor of the kind capped by a massive concrete dome, a NuScale plant has up to 12 individual reactors made up of self-contained modules, each immersed in water and encapsulated by steel. The 65-foot long by 14-foot wide modules will be manufactured under controlled conditions at a central factory and shipped to sites, dramatically cutting down costs. Four modules can power the city of Madison, Wisconsin. All twelve can light up the entire metropolitan area of Memphis, Tennessee.
Because a NuScale plant is broken up into self-contained mini reactors of 45-megawatts each, the failure scenarios only pose so much risk, says Dr. Mohammad Modarres, professor of mechanical and nuclear engineering at the University of Maryland and an international leader in the science of probabilistic risk assessment.
Probabilistic Risk Assessments (PRAs) are the most rigorous step for any engineering design, and take months to produce after numerous computer models based data sources like materials analyses. Engineers begin by brainstorming hundreds of possible system failures, searching for any possible way that radiation could find its way into the environment, and then determine a frequency for every conceivable scenario, in the end determining the possible consequences for each outcome. Three Mile Island had just such a PRA, which was highly prescient and laid out a scenario of system and human error virtually identical to what happened there, but the plant's owners and federal regulators didn't heed its warnings at the time. PRAs earned new status in TMI's aftermath.
The Nuclear Regulatory Commission requires PRAs for new designs and established plants alike, using methods standardized by the mechanical engineering profession. Much as the Food and Drug Administration mandates a series of clinical trials to assess the efficacy and safety of a prospective drug, the NRC's layers of regulators and outside consultants examine PRA data. Dr. Modarres performed NuScale's PRA just as he has done for large scale reactors and presented his findings at last year's International Probabilistic Safety Assessment & Management Conference.
Dr. Modarres says NuScale is the safest reactor he's ever come across, 10,000 times less risk of any level of core damage than currently operating standard reactors, and it's 10 times safer than the Westinghouse AP1000 plants China's building now (pending NRC approval, it's also the design that will go up in Georgia).
So what if a natural disaster cut of external power to NuScale's water pumps that cool the reactor core -- the exact scenario now playing out in Japan?
It can't happen. There are no pumps.
In the NuScale plant, "You don't need a pump -- the heat creates a current of water by natural physics. Everything works by natural phenomena." Instead, the plant's steam generator tube is its weakest link, contributing the largest fraction of its 1 in 100-million-year risk. Physical properties of the tube which carries hot steam to the electricity-generating turbine come into play in the analysis. The tube could rupture, sending radioactive steam into the turbine and depriving the reactor core of water. In NuScale's PRA, Dr. Modarres created technical models of possible wear and tear of the pipe and its safety valves that could occur over the years. "We calculate through the 'physics of failure' an estimated frequency for this event," he says. The model gets even more complex, as the reactor automatically replenishes its water (or human operators can do so) through chemical volume control systems. The PRA models have to take into account the likelihood of this system failing too.
NuScale takes advantage of its design simplicity during its pre-NRC submission phase to change out elements and see how that affects its PRA (that pipe may get further tweaking before the NRC sees it). Such revisions on the fly aren't even possible with most larger more complex plants.
The reactor's size is one of its most important safety features. At 1/26th the size of standard reactors, there's simply less radioactivity to let loose. Dr. Reyes told the MIT crowd, "We've not only reduced the frequency of possible accidents, we reduced the consequences of accidents. That's huge psychologically." People who are afraid of flying don't really care about the frequency of accidents he says, it's the huge consequences of a single accident. "We've eliminated that."
Dr. Modarres explains the worst-case disaster scenario this way: "Even if one of the reactors fails and releases its radiation into the containment vessel, and again if that containment vessel fails and releases its material, it would be releasing that material into water, which is one of the best scrubbers for radioactive material." Ultimately a small amount of radioactive gases could make their way into the atmosphere, but mind you the whole operation is in an underground silo.
Since each module has its own separate metal containment vessel (unlike the traditional design of concrete domes that are getting repeatedly blasted in the hydrogen-fueled explosions at the Fukushima Daiichi plant), the probability of two reactors both leaking radiation is the probability of two independent extremely unlikely events. Even more reactors? Infinitesimal.
What about a major earthquake? "Being inside water, the forces that would be applied to the modules is much less. It's floating inside the water, so they wouldn't have as much force as if they were tied into the ground." Detailed seismic assessments are still being built into the model, and depend on location, but Dr. Modarres does not expect such events will increase major risk significantly.
Representative Edward Markey (D-MA) was sounding the alarm bells this weekend, yesterday sending a letter to President Obama requesting a moratorium on new nuclear power plants, reminiscent of European Greens. In light of the dire challenge posed by global warming, the growing destabilization in OPEC countries, and the ingenuity of America's nuclear engineers, the more appropriate federal response to the vulnerabilities in old nuclear plant designs that we share with Japan is to fully back nuclear energy 2.0 companies like NuScale.
Emma Perrier was deceived by an older man on the internet—a hoax that turned into an unbelievable love story.
Emma Perrier spent the summer of 2015 mending a broken heart, after a recent breakup. By September, the restaurant manager had grown tired of watching The Notebook alone in her apartment in Twickenham, a leafy suburb southwest of London, and decided it was time to get back out there. Despite the horror stories she’d heard about online dating, Emma, 33, downloaded a matchmaking app called Zoosk. The second “o” in the Zoosk logo looks like a diamond engagement ring, which suggested that its 38 million members were seeking more than the one-night stands offered by apps like Tinder.
She snapped the three selfies the app required to “verify her identity.” Emma, who is from a volcanic city near the French Alps, not far from the source of Perrier mineral water, is petite, and brunette. She found it difficult to meet men, especially as she avoided pubs and nightclubs, and worked such long hours at a coffee shop in the city’s financial district that she met only stockbrokers, who were mostly looking for cappuccinos, not love.
Two centuries ago, America pioneered a way of thinking that puts human well-being in economic terms.
Money and markets have been around for thousands of years. Yet as central as currency has been to so many civilizations, people in societies as different as ancient Greece, imperial China, medieval Europe, and colonial America did not measure residents’ well-being in terms of monetary earnings or economic output.
In the mid-19th century, the United States—and to a lesser extent other industrializing nations such as England and Germany—departed from this historical pattern. It was then that American businesspeople and policymakers started to measure progress in dollar amounts, tabulating social welfare based on people’s capacity to generate income. This fundamental shift, in time, transformed the way Americans appraised not only investments and businesses but also their communities, their environment, and even themselves.
Facebook and Google's push to personalize the news is the latest seismic shift in tech giants’ influence on the information landscape.
It took a terrorist attack for Google to enter the news business.
On September 11, 2001, after hijackers crashed two commercial jets into the World Trade Center as well as a third plane into the Pentagon and another into a field near Shanksville, Pennsylvania, internet users turned to the search engine for information. Again and again, they typed in terms like “New York Twin Towers,” but found nothing about what had happened that morning. Google’s web crawlers hadn’t indexed “Twin Towers” since the month before, which meant every result that Google returned was, given the context, totally and painfully irrelevant.
More comfortable online than out partying, post-Millennials are safer, physically, than adolescents have ever been. But they’re on the brink of a mental-health crisis.
One day last summer, around noon, I called Athena, a 13-year-old who lives in Houston, Texas. She answered her phone—she’s had an iPhone since she was 11—sounding as if she’d just woken up. We chatted about her favorite songs and TV shows, and I asked her what she likes to do with her friends. “We go to the mall,” she said. “Do your parents drop you off?,” I asked, recalling my own middle-school days, in the 1980s, when I’d enjoy a few parent-free hours shopping with my friends. “No—I go with my family,” she replied. “We’ll go with my mom and brothers and walk a little behind them. I just have to tell my mom where we’re going. I have to check in every hour or every 30 minutes.”
Those mall trips are infrequent—about once a month. More often, Athena and her friends spend time together on their phones, unchaperoned. Unlike the teens of my generation, who might have spent an evening tying up the family landline with gossip, they talk on Snapchat, the smartphone app that allows users to send pictures and videos that quickly disappear. They make sure to keep up their Snapstreaks, which show how many days in a row they have Snapchatted with each other. Sometimes they save screenshots of particularly ridiculous pictures of friends. “It’s good blackmail,” Athena said. (Because she’s a minor, I’m not using her real name.) She told me she’d spent most of the summer hanging out alone in her room with her phone. That’s just the way her generation is, she said. “We didn’t have a choice to know any life without iPads or iPhones. I think we like our phones more than we like actual people.”
The Centers for Disease Control and Prevention (CDC) keeps a Most Wanted list for flu viruses. The agency evaluates every potentially dangerous strain, and gives them two scores out of 10—one reflecting how likely they are to trigger a pandemic, and another that measures how bad that pandemic would be. At the top of the list, with scores of 6.5 for emergence and 7.5 for impact, is H7N9.
Influenza viruses come in many flavors—H5N1, H1N1, H3N2, and so on. The H and N refer to two proteins on their surface, and the numbers refer to the versions of those proteins that a particular virus carries. H1N1 was responsible for both the catastrophic pandemic of 1918 that killed millions of people, and the most recent (and much milder) one from 2009. H5N1 is the bird-flu subtype that has been worrying scientists for almost two decades. But H7N9? Until recently, it had flown under the radar.
In western Germany, populations of flying insects have fallen by around 80 percent in the last three decades.
The bottles were getting emptier: That was the first sign that something awful was happening.
Since 1989, scientists from the Entomological Society Krefeld had been collecting insects in the nature reserves and protected areas of western Germany. They set up malaise traps—large tents that funnel any incoming insect upward through a cone of fabric and into a bottle of alcohol. These traps are used by entomologists to collect specimens of local insects, for research or education. “But over the years, [the Krefeld team] realized that the bottles were getting emptier and emptier,” says Caspar Hallmann, from Radboud University.
By analyzing the Krefeld data—1,503 traps, and 27 years of work—Hallmann and his colleagues have shown that most of the flying insects in this part of Germany are flying no more. Between 1989 and 2016, the average weight of insects that were caught between May and October fell by an astonishing 77 percent. Over the same period, the weight of insects caught in the height of summer, when these creatures should be at their buzziest, fell by 82 percent.
An increasing number of American mayors are trying to channel recent economic growth to neglected neighborhoods.
With most big cities’s economies continuing to grow, the most pressing issue they face is how to connect their low-income communities to the opportunities that growth creates. New efforts developing in Charlotte, North Carolina, and Chicago show the many creative alternatives cities are exploring to respond to that challenge—and the obstacles they face.
From 2010 through 2015, all of the 100 largest metropolitan areas added jobs, and 98 of them increased their total economic output, according to calculations by the Brookings Institution’s Metropolitan Policy Program.
But in most cities, that revival has largely bypassed communities of concentrated poverty, like large swathes of Chicago’s predominantly African-American South Side or mostly Hispanic East Charlotte. Across the country, many cities have fueled their growth by importing streams of young college graduates from elsewhere, while struggling to place their own low-income kids on a track to obtain the education necessary to compete for those same jobs. Compounding the problem, longtime residents and commercial establishments in moderate- and low-income neighborhoods can find themselves pushed out by rising rents as developers pursue young white-collar workers flocking to urban environments.
A 27-year-old mayor is implementing a $1 million experiment in guaranteed income for residents of a poor city just outside the Bay Area.
The latest experiment in a universal basic income will be coming to Stockton, California, in the next year.
With $1 million in funding from the tech industry–affiliated Economic-Security Project, the Stockton Economic-Empowerment Demonstration (SEED) will be the country’s first municipal pilot program. As currently envisioned, some number of people in Stockton will receive $500 per month. That’s not enough to cover all their expenses, but it could help people with rising housing costs, paying student loans, or simply saving for life’s inevitable problems.
Last year, Stockton rents rose more than 10 percent, putting the city’s rental price growth among the top 10 in the nation. This is quite a surprise in what Time called “America’s most miserable city” just three years ago. The average rent remains a modest-by-Bay-standards $1,051, but Stockton has a per-capita income of just $23,046, more than $6,000 less than the U.S. median and a full $8,500 less than the California median. If you made the per-capita income of the city, average rent alone would eat 55 percent of your income.
A series of damaging stories about the president's methods of consoling grieving Gold Star families represent the president’s latest entirely self-inflicted wound.
The question to President Trump on Monday sounded relatively innocuous: “Why haven’t we heard anything from you so far about the soldiers that were killed in Niger? And what do you have to say about that?” It’s certainly not the kind of question that seemed likely to set off several days of heated controversy.
But the hubbub that has ensued, centering on Trump’s response to the deaths of four soldiers in Niger and, more broadly, the way he deals with grieving military families, is yet another example of how this president inflicts crises on himself. This pattern has happened several times since Trump entered office, with the tussle over the size of his crowd on Inauguration Day and his claim that Barack Obama “wiretapped him.” In each case, Trump’s bluster and his seeming obsession with Obama have led him to commit serious unforced errors.
The foundation of Donald Trump’s presidency is the negation of Barack Obama’s legacy.
It is insufficient to statethe obvious of Donald Trump: that he is a white man who would not be president were it not for this fact. With one immediate exception, Trump’s predecessors made their way to high office through the passive power of whiteness—that bloody heirloom which cannot ensure mastery of all events but can conjure a tailwind for most of them. Land theft and human plunder cleared the grounds for Trump’s forefathers and barred others from it. Once upon the field, these men became soldiers, statesmen, and scholars; held court in Paris; presided at Princeton; advanced into the Wilderness and then into the White House. Their individual triumphs made this exclusive party seem above America’s founding sins, and it was forgotten that the former was in fact bound to the latter, that all their victories had transpired on cleared grounds. No such elegant detachment can be attributed to Donald Trump—a president who, more than any other, has made the awful inheritance explicit.
