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.
The 49ers quarterback won’t stand for the national anthem anymore.
San Francisco 49ers quarterback Colin Kaepernick’s refusal to stand for the national anthem before games as a protest against recent high-profile incidents of police brutality and racial injustice have been met with criticism and protests, but is an important step for a league where professional athletes rarely speak out on such issues.
Kaepernick was noticed sitting down during the playing of “The Star Spangled Banner” in a preseason game Friday. When asked by a reporter about his actions, he said:
I am not going to stand up to show pride in a flag for a country that oppresses black people and people of color. To me, this is bigger than football and it would be selfish on my part to look the other way. There are bodies in the street and people getting paid leave and getting away with murder.
What looks at first glance like an opening up of possibilities is actually an attack on the human imagination.
You might not like what I’m about to say about the multiverse. But don’t worry; you’ve already had your revenge. If there are an infinite number of parallel universes, there will be any number of terrible dictatorships, places where life has become very difficult for people who like to string words together. Somewhere out there, there’s a society in which every desperate little essay like this one comes with a tiny, unremarkable button: push it, and the author will be immediately electrocuted to death.
Maybe your hate is more visceral—you already know I’ll die some day, but you want to see it happen; you need to see me groveling. You can if you want. Fly upwards from the plane of our solar system, keep on going, through the endless huddles of galaxies, never forgetting your purpose, until space and time run out altogether. Eventually you’ll find yourself in another universe, on a damp patch of grass and broken concrete, unwatched by whatever local gang or galactic empire rules the city rising in foggy shapes beyond the marshes. There, you’ll see a creature strangely similar to yourself, beating me to death with whatever bits of scrap are lying around.
As pay TV slowly declines, cable news faces a demographic cliff. And nobody has further to fall than the merchant of right-wing outrage.
Updated at 12:05 p.m.
October 7, 2016, will be the 20th birthday of the Fox News Channel, and at the moment, the network is experiencing the soap-operatic highs and lows typical of any teenager on television. In many ways, the summer of 2016 may go down in Fox News history as the company’s nadir. Its founder and leader Roger Ailes has been dishonorably dispatched, the remaining executives are dealing with a flurry of sexual harassment lawsuits, and one of its most public faces, Sean Hannity, has ignominiously remodeled himself as a gutless Trump whisperer.
And yet Fox News’ fortunes are ascendant, at least in the most quantifiable sense. The network’s annual profit in 2015 soared by about 20 percent. For the first time ever, Fox News has been the most-watched cable network among both primetime and daytime viewers for several months, with a larger audience than its nominal rivals, CNN and MSNBC, combined. Led by “The O'Reilly Factor,” Fox News doesn’t just have the best-rated news show on cable television; according to The Wrap, it has the 13 best-rated news shows on cable television.
Why did the company trend a false article about Megyn Kelly?
Oh, Facebook. Just when the company seems to have avoided the responsibility of being a news organization (and all the attendant controversy), it finds itself back in the editorial muck.
Last week, Facebook made a surprise overhaul of its “Trending Stories” feature, the sidebar that highlights some of the most popular news stories on Facebook. Where the company had previously provided a short, human-written summary of the news at hand, it now only described the story in a one or two-word phrase: “#Toyko2020: Japanese Prime Minister Appears in Surprise Performance During Rio Ceremony,” became just “#Tokyo2020.”
Facebook’s decision to simplify the feature seemed like an attempt to wriggle out of editorial responsibility: What had been a messy human-led process would now become an algorithm-guided one. The company also laid off the 26 employees who had run the feature—19 curators and seven copyeditors—with little warning on Friday, according to Quartz.
Hillary Clinton has her problems, but Donald Trump is unfit for the presidency.
On one hand, there’s former Secretary of State Hillary Clinton, who oversaw “grossly inadequate” security at a diplomatic facility in Benghazi, Libya, the site of a deadly September 11, 2012, terrorist attack.
A new anatomical understanding of how movement controls the body’s stress response system
Elite tennis players have an uncanny ability to clear their heads after making errors. They constantly move on and start fresh for the next point. They can’t afford to dwell on mistakes.
Peter Strick is not a professional tennis player. He’s a distinguished professor and chair of the department of neurobiology at the University of Pittsburgh Brain Institute. He’s the sort of person to dwell on mistakes, however small.
“My kids would tell me, dad, you ought to take up pilates. Do some yoga,” he said. “But I’d say, as far as I’m concerned, there's no scientific evidence that this is going to help me.”
Still, the meticulous skeptic espoused more of a tennis approach to dealing with stressful situations: Just teach yourself to move on. Of course there is evidence that ties practicing yoga to good health, but not the sort that convinced Strick. Studies show correlations between the two, but he needed a physiological mechanism to explain the relationship. Vague conjecture that yoga “decreases stress” wasn’t sufficient. How? Simply by distracting the mind?
In the name of emotional well-being, college students are increasingly demanding protection from words and ideas they don’t like. Here’s why that’s disastrous for education—and mental health.
Something strange is happening at America’s colleges and universities. A movement is arising, undirected and driven largely by students, to scrub campuses clean of words, ideas, and subjects that might cause discomfort or give offense. Last December, Jeannie Suk wrote in an online article for The New Yorker about law students asking her fellow professors at Harvard not to teach rape law—or, in one case, even use the word violate (as in “that violates the law”) lest it cause students distress. In February, Laura Kipnis, a professor at Northwestern University, wrote an essay in The Chronicle of Higher Education describing a new campus politics of sexual paranoia—and was then subjected to a long investigation after students who were offended by the article and by a tweet she’d sent filed Title IX complaints against her. In June, a professor protecting himself with a pseudonym wrote an essay for Vox describing how gingerly he now has to teach. “I’m a Liberal Professor, and My Liberal Students Terrify Me,” the headline said. A number of popular comedians, including Chris Rock, have stopped performing on college campuses (see Caitlin Flanagan’s article in this month’s issue). Jerry Seinfeld and Bill Maher have publicly condemned the oversensitivity of college students, saying too many of them can’t take a joke.
What to do if you’re a Hillary fan seated next to a Trump supporter at a wedding
When America is finally great again, they’ll make the latte with soy milk like you asked.
All those political cracks, not to mention earnest proclamations, mean that for the next 10 weeks, many casual interactions run the risk of erupting into full-blown partisan warfare. It’s more of a danger for those with family members or close friends who support opposing candidates and views. But on Facebook, hot-button scuffles can break out between almost anyone. (I recently witnessed a college friend who lives in Europe arguing about gun rights with a random guy from my high school in Texas, whom I myself have spoken with only a few times in person.)
One reason Americans find the other side’s views so inflammatory is that increasingly, they view their political party as more of a tribe than a checkbox. “People start seeing themselves or their political views as the main representation of their values, and what is right and wrong,” said Emanuel Maidenberg, a clinical professor of psychiatry and biobehavioral sciences at UCLA.
In the primaries, he avoided policy debates by promising to build a wall—but the general election is forcing him into specifics.
The biggest political story of the last week has been Donald Trump’s flip-flop on deporting undocumented immigrants. This Sunday on CNN, Mike Pence filibustered his way through the subject for almost seven minutes before Jake Tapper finally declared, “You did not address the issue” and moved on. Chris Christie on ABC and Kellyanne Conway on CBS were no more coherent. The Daily Beast summed up the morning with the headline, “Immigration Flip-Flop Leaves Trump Campaign Flailing on Sunday Shows.”
But focusing on Trump’s “flip-flop” misses the point. Trump’s real problem isn’t that he’s changed his position on immigration. It’s that he’s trying to formulate one at all.
What the commentary of the last few days has generally overlooked is that while immigration was key to Trump’s success in the Republican primary, Trump never actually offered an immigration policy. To the contrary, his success rested in large measure on his ability to avoid one. Trump’s strategy on immigration, as on other key issues, was to cut through the Gordian knot of public policy with aggressive, quick fix solutions. Terrorism? Ban Muslims. ISIS? Bomb the hell out of them and take their oil. Loss of manufacturing jobs? Slap massive tariffs on companies that outsource American jobs.
The performer, known for his roles inWilly Wonka and the Chocolate Factory and Young Frankenstein, died at age 83.
Gene Wilder was the greatest kind of comic actor: one who not only knew how to read a joke, but also how to inhabit it. In his hands, a line reading could be suffused with menace, or compassion, or demented delight, and no matter what, it would be deeply funny to behold. Wilder, who died at age 83 on Monday due to complications from Alzheimer’s disease, was a consummate performer who made every project he worked on better, from Mel Brooks’ masterpieces of the 1970s to his collaborations with Richard Pryor. He was a screen presence who always seemed to possess an otherworldly energy, making him the obvious (and best) choice to play Willy Wonka, Roald Dahl’s avatar of sheer wonder. His footprint as a comic actor was immense, with his best work showing the depth of craft that went into building a memorable performance.
