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.
It isn’t the only democratic institution that finds itself in danger.
Four years ago, as a speechwriter for President Obama, I commissioned a binder full of women.
A little context. It was the morning of the Al Smith Dinner, the election-year tradition in which both parties’ nominees don white-tie attire and deliver comedy monologues to New York City’s elite. Our opponent, Governor Mitt Romney had recently used the words “binders full of women” while discussing gender parity in government. Eager to mock the clumsy phrase, I asked a staffer on the advance team to put together a prop.
But our binder never saw the light of day. Obama nixed the idea. I remember being disappointed by the president’s decision, and wondering if POTUS was phoning it in. Of the jokes that did make it into the final draft, one in particular stood out for its authenticity.
The easiest way to take down the web is to attack people’s access to it.
For more than two hours on Friday morning, much of the web seemed to grind to a halt—or at least slow to dial-up speed—for many users in the United States.
More than a dozen major websites experienced outages and other technical problems, according to user reports and the web-tracking site downdetector.com. They included The New York Times, Twitter, Pinterest, Reddit, GitHub, Etsy, Tumblr, Spotify, PayPal, Verizon, Comcast, EA, the Playstation network, and others.
How was it possible to take down all those sites at once?
Someone attacked the architecture that held them together—the domain-name system, or DNS, the technical network that redirects users from easy-to-remember addresses like theatlantic.com to a company’s actual web servers. The assault took the form of a distributed denial-of-service attack (DDoS) on one of the major companies that provides other companies access to DNS. A DDoS attack is one in which an attacker floods sites “with so much junk traffic that it can no longer serve legitimate visitors,” as the security researcher Brian Krebs put it in a blog post Friday morning.
“Light” events are some of the heaviest lifting in political life. Comedy is hard to begin with, and for the kinds of people involved in politics, jokes are vastly more difficult to write or deliver than “substantive” remarks. And for presidents or presidential aspirants, we’re talking about a special kind of joke. These eminent figures need to come across as “modest” and self-deprecatory, but only up to a humble-brag point. (That is, just enough so that the audience and reviewers will say, “Oh, isn’t it charming that he’s willing to laugh at himself!”) Real comedy often includes a “what the hell!” willingness to say something that will genuinely offend or shock, which national politicians can’t afford to do. The White House Correspondents Dinner, the Gridiron event, the Al Smith Dinner—any event like this is hard (as David Litt, a former member of the Obama speechwriting team, explains in a very nice item just now).
First there was McCain’s caving to Bush’s signing statement on his own torture bill, then his selection of an extremely unqualified and unvetted running mate, then he backed Trump until nearly the bitter end—even after Trump insulted his POW experience and his fellow vets with PTSD. And now, a shameless betrayal of constitutional principle that would have gotten far more attention this week if Trump hadn’t one-upped McCain with all his incendiary “rigged” rhetoric. Reader Don explains:
I don’t know if your readers have seen this yet, but it seems that McCain has announced that his fellow GOP Senators will not confirm any Supreme Court nomination by Clinton. Trump is an ignorant, narcissistic, nasty piece of work. But McCain used to be a guy who remembered and honored (at least sometimes) the old bipartisan traditions of the Senate. His statement is just outrageous and inexcusable. What he’s basically saying is that only Republican presidents get to appoint Supreme Court Justices.
I understand that their thinking is that they don’t want the bias of the Court to shift from conservative to liberal. But the Court has shifted back and forth over the years, and we have managed to survive those changes. Apparently, today’s Republican Party feels that the country somehow won’t survive a Democratic administration or a liberal Supreme Court.
We have what might be described as an asymmetric politics. One party disagrees with the other party’s policy domestic policy positions, but recognizes the legitimacy of an opposition party and accepts that the other party is patriotic and loyal to the country. The other party rejects the legitimacy and loyalty of the other party. The efforts to de-legitimize former President Clinton, President Obama, and likely future President Hillary Clinton are part of this effort. The refusal of the GOP Congress to allow Obama any legislative accomplishments was another part of it. I expect that a GOP House will adopt the same obstructionist tactics starting in 2017.
People predict that the U.S. population will continue to get younger, better educated, and less white. I hope our political experiment lasts long enough to see that day.
The candidates are back on the campaign trail, following the third, and final, debate on Wednesday night.
It’s Friday, October 21—the election is now less than three weeks away. Donald Trump and Hillary Clinton are back on the campaign trail to deliver their final pitch to voters, ahead of Election Day. We’ll bring you the latest updates from the trail, as events unfold. Also see our continuing coverage:
Science says lasting relationships come down to—you guessed it—kindness and generosity.
Every day in June, the most popular wedding month of the year, about 13,000 American couples will say “I do,” committing to a lifelong relationship that will be full of friendship, joy, and love that will carry them forward to their final days on this earth.
Except, of course, it doesn’t work out that way for most people. The majority of marriages fail, either ending in divorce and separation or devolving into bitterness and dysfunction. Of all the people who get married, only three in ten remain in healthy, happy marriages, as psychologist Ty Tashiro points out in his book The Science of Happily Ever After, which was published earlier this year.
Social scientists first started studying marriages by observing them in action in the 1970s in response to a crisis: Married couples were divorcing at unprecedented rates. Worried about the impact these divorces would have on the children of the broken marriages, psychologists decided to cast their scientific net on couples, bringing them into the lab to observe them and determine what the ingredients of a healthy, lasting relationship were. Was each unhappy family unhappy in its own way, as Tolstoy claimed, or did the miserable marriages all share something toxic in common?
Among the major sites that had trouble staying online or functioning properly: The New York Times, Twitter, Pinterest, Reddit, GitHub, Etsy, Tumblr, Spotify, PayPal, Verizon, Comcast, EA, and the Playstation network. Aside from the inconvenience to those attempting to visit those sites, there’s the question of how an attack like this affects the companies who run those sites. System outages—even seemingly brief ones—can have huge repercussions on the bottom line.
AT&T is reportedly in advanced talks to buy Time Warner, South Africa says it will leave the ICC, ISIS attacks Kirkuk, and more from across the United States and around the world.
—The Wall Street Journal is reporting that a deal for AT&T to buy Time Warner could come as early as this weekend. More here
—South Africa has notified the UN that it is withdrawing from The Hague-based International Criminal Court. A government minister said South Africa didn’t want to carry out ICC arrest warrants against other African leaders—warrants, he said, that would lead to “regime change.” More here

How the national mythos and U.S. labor laws influence geographic mobility.
Kevin Bacon moves from a big city to a small town in Middle America where dancing is outlawed. Ralph Macchio moves from New Jersey to California, where he learns the art of life and combat. Dianne Wiest moves with her two sons to a California town stocked with vampires.
The trope of American families settling in faraway places isn’t just a plotline for terrible 1980s movies, but a national phenomenon. Decades of data, including a more recent Gallup study, characterizes the United States as one of the most geographically mobile countries in the world. “About one in four U.S. adults (24 percent) reported moving within the country in the past five years,” the report noted. With the comparable exceptions of Finland (23 percent) and Norway (22 percent), Americans also move considerably more than their European peers.
Why her vow not to “add a penny to the debt” is an impossible pledge to keep
Hillary Clinton said nothing on Wednesday night that should derail her considerable chances of winning the presidency on November 8. But if she wins, one simple promise she repeated over and over again could come back to haunt her reelection bid in 2020.
“I also will not add a penny to the debt,” Clinton said toward the beginning of her final presidential-debate performance. She made a similar pledge two more times that night, and it’s a line she has used before on the campaign trail. It’s a short-hand reference to the fact that although she has proposed hundreds of billions in new federal spending for infrastructure, paid family leave, education, and other items, she would pay for those investments by raising an equal or greater amount in revenue through higher taxes on the wealthy and corporations.
