U.S. GAO – Key Issues: Disposal of High-Level Nuclear Waste

The United States has over 90,000 metric tons of nuclear waste that requires disposal. The U.S. commercial power industry alone has generated more waste (nuclear fuel that is “spent” and is no longer efficient at generating power) than any other country—nearly 80,000 metric tons. This spent nuclear fuel, which can pose serious risks to humans and the environment, is enough to fill a football field about 20 meters deep. The U.S. government’s nuclear weapons program has generated spent nuclear fuel as well as high-level radioactive waste and accounts for most of the rest of the total at about 14,000 metric tons, according to the Department of Energy (DOE). For the most part, this waste is stored where it was generated—at 80 sites in 35 states. The amount of waste is expected to increase to about 140,000 metric tons over the next several decades. However, there is still no disposal site in the United States. After spending decades and billions of dollars to research potential sites for a permanent disposal site, including at the Yucca Mountain site in Nevada that has a license application pending to authorize construction of a nuclear waste repository, the future prospects for permanent disposal remain unclear.

Opinion | Awash in Radioactive Waste – The New York Times

On its 60th anniversary, the civilian age of nuclear power in America appears to be almost over. But with the country awash in radioactive waste and plutonium stockpiled for warheads, the task of managing this atomic legacy grows ever more urgent. Opening a long-delayed waste repository at Yucca Mountain in Nevada is imperative.

President Dwight Eisenhower formally opened America’s first commercial nuclear power station at Shippingport, Pa., near Pittsburgh, on May 26, 1958. He declared it would “put the atom to work for the good of mankind, not his destruction.” His nuclear cheerleader, Lewis Strauss, chairman of the Atomic Energy Commission, had promised power “too cheap to meter.”

Today, with cheap gas and falling prices for wind and solar energy, nuclear power is often now too expensive to sell. Six plants closed from 2013 to 2017. At least seven more — from the Oyster Creek plant in New Jersey to the Diablo Canyon plant in California — have been earmarked for final shutdown, often years before their operating licenses expire. About a quarter of the nation’s nuclear power plants don’t cover their operating costs, according to a recent analysis by Bloomberg New Energy Finance.

If true, this could be one of the greatest discoveries in human history – U.S. News – Haaretz.com

“I don’t care what people say,” asserts Avi Loeb, chairman of Harvard University’s astronomy department and author of one of the most controversial articles in the realm of science last year (and also one of the most popular in the general media). “It doesn’t matter to me,” he continues. “I say what I think, and if the broad public takes an interest in what I say, that’s a welcome result as far as I’m concerned, but an indirect result. Science isn’t like politics: It is not based on popularity polls.”

Prof. Abraham Loeb, 56, was born in Beit Hanan, a moshav in central Israel, and studied physics at the Hebrew University of Jerusalem as part of the Israel Defense Forces’ Talpiot program for recruits who demonstrate outstanding academic ability. Freeman Dyson, the theoretical physicist, and the late astrophysicist John Bahcall admitted Loeb to the Institute for Advanced Study in Princeton, whose past faculty members included Albert Einstein and J. Robert Oppenheimer. In 2012, Time magazine named Loeb one of the 25 most influential people in the field of space. He has won prizes, written books and published 700 articles in the world’s leading scientific journals. Last October, Loeb and his postdoctoral student Shmuel Bialy, also an Israeli, published an article in the scientific outlet “The Astrophysical Journal Letters,” which seriously raised the possibility that an intelligent species of aliens had sent a spaceship to Earth.

Earth’s magnetic field is acting up and geologists don’t know why

Something strange is going on at the top of the world. Earth’s north magnetic pole has been skittering away from Canada and towards Siberia, driven by liquid iron sloshing within the planet’s core. The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move.

On 15 January, they are set to update the World Magnetic Model, which describes the planet’s magnetic field and underlies all modern navigation, from the systems that steer ships at sea to Google Maps on smartphones.

The most recent version of the model came out in 2015 and was supposed to last until 2020 — but the magnetic field is changing so rapidly that researchers have to fix the model now. “The error is increasing all the time,” says Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration’s (NOAA’s) National Centers for Environmental Information.

Repair Cafes Aim to Fix Our Throwaway Culture – CityLab

Repair cafes. What a brilliant idea!

We were at a “repair cafe” inside the Elkridge Library in Howard County, Maryland. Instead of silence, we were surrounded by the buzzing of power drills and the whirring of sewing machines. Goedeke was one of the “master fixers” there. He doesn’t like the term, though; he says it should be reserved for the professionals. “We’re all just amateurs at this, and we’re just having fun, mostly,” the 67-year-old retired engineer said.

Around the room, 10 others were helping residents repair everything from tables and lamps to jewelry and clothing. In one corner, a handful of vacuums had begun to accumulate. These were things people normally threw away when they malfunction. “[Our society] has been inculcated in the last 50 years with this disposable concept and to buy the best and the latest,” Goedeke said. “We just don’t expect to keeps things around.”

26 Years of Growth: Shanghai Then and Now – The Atlantic

Reuters photographer Carlos Barria recently spent time in Shanghai, China, the fastest-growing city in the world. A week ago, he took this amazing shot, recreating the same framing and perspective as a photograph taken in 1987, showing what a difference 26 years can make. The setting is Shanghai’s financial district of Pudong, dominated by the Oriental Pearl Tower at left, and the new 125-story Shanghai Tower, China’s tallest building and the world’s second tallest skyscraper, at 632 meters (2,073 ft) high, scheduled to finish by the end of 2014. Shanghai, the largest city by population in the world, has been growing at a rate of about 10 percent a year the past 20 years, and now is home to 23.5 million people — nearly double what it was back in 1987. This entry is focused on this single photo pairing, with several ways to compare the two.

It Was Vulture Capitalism that Killed Sears

If you’ve been following the impending bankruptcy of America’s iconic retailer, as covered by print, broadcast, and digital media, you’ve probably encountered lots of nostalgia, and sad clucking about how dinosaurs like Sears can’t compete in the age of Amazon and specialty retail.

But most of the coverage has failed to stress the deeper story. Namely, Sears is a prime example of how hedge funds and private-equity companies take over retailers, encumber them with debt in order to pay themselves massive windfall profits, and then leave the retailer without adequate operating capital to compete. Part of the strategy is to sell off valuable real estate, the better to enrich the hedge fund, and stick the retail company with costly rental payments to occupy the space that it once owned.

‘Hyperalarming’ study shows massive insect loss – The Washington Post

Insects around the world are in a crisis, according to a small but growing number of long-term studies showing dramatic declines in invertebrate populations. A new report suggests that the problem is more widespread than scientists realized. Huge numbers of bugs have been lost in a pristine national forest in Puerto Rico, the study found, and the forest’s insect-eating animals have gone missing, too.

In 2014, an international team of biologists estimated that, in the past 35 years, the abundance of invertebrates such as beetles and bees had decreased by 45 percent. In places where long-term insect data are available, mainly in Europe, insect numbers are plummeting. A study last year showed a 76 percent decrease in flying insects in the past few decades in German nature preserves.

After Soyuz Failure, Space Is Now Weirdly Inaccessible to Astronauts

All crewed launches have been suspended by Russia’s space agency following yesterday’s Soyuz rocket failure. That’s a problem, because much of the world relies on Russian rockets to get both cargo and people into space. Consequently, we’re now facing the very real possibility of having an uncrewed International Space Station—something that hasn’t happened in nearly two decades.
