Where Should We Store Nuclear Waste?

In 35 states across the U.S., small fuel rods once used to produce nuclear power sit in storage facilities, mostly at nuclear power plants. The facilities are temporary — the United States has no permanent disposal spots for this kind of waste, according to the United States Nuclear Regulatory Commission. And despite decades of work, we’re nowhere close to a real solution.
That’s not to say there aren’t plenty of ideas. Most bury the waste deep underground, in large repositories of rock or in drilled columns. But each has its issues. Not all rocks are created equally, for example; some have characteristics better suited to containing the dangerous radioactive waste than others.
Christopher Neuzil, a United States Geological Survey geologist, prefers shale. When looking for a good place to bury waste, one important factor is the rock’s permeability — “the ease with which fluid can flow through the rock,” Neuzil told weather.com. “One of the things you worry about with a repository is whether you’re going to have groundwater flowing through the repository, picking up contaminants and delivering them to places you don’t want them to go.”
A clay-rich sedimentary rock found in great abundance, shale has very low permeability, making it a popular option and one Switzerland, France and Belgium are currently considering. Granite is another possibility, but tends to fracture and experience faults, Neuzil said. Neuzil discussed both options at this week’s Geological Society of America (GSA) meeting in Denver.
“Deep boreholes” — drilling columns more than 16,000 feet deep into the Earth to hold the contained waste and then sealing them off for good — could also work. But they carry their own issues, according to Bret Leslie, senior staff with the U.S. Nuclear Waste Technical Review Board (NWTRB), who discussed the boreholes at the GSA meeting.
The technology and expertise for drilling the holes is about 30 to 40 years behind that of geologic disposal, Leslie told weather.com, and while they are feasible, research into using the holes shouldn’t impede exploring the possibilities of repositories.
In a July letter to the Department of Energy, Rodney Ewing, chair of NWTRB, outlined the difficulties facing deep boreholes, including attempting to characterize the rock found at such depths and the large number of boreholes necessary, in addition to the new technologies needed. “Because of these technological challenges and the significant scale of a deep borehole disposal program,” the letter states, “the Board reiterates its long-standing support of mined geologic disposal.”
The problem of disposing of our waste is not just a scientific one. In fact, Neuzil said, the technical issues aren’t necessarily that difficult. What’s preventing a plan from moving forward has far more to do with politics than science, including very high safety thresholds for repositories, he added. “They’re unrealistically stringent, in my view.”
This is a decades-old battle. In 1982, Congress passed the Nuclear Waste Policy Act. A 1987 amendment directed the DOE to bury the waste at Yucca Mountain, 100 miles north of Las Vegas, a process set to have started in 1998. But political pressures caused defunding of the so-called Yucca Mountain Project in 2010, leaving a law on the books requiring waste burial at Yucca but not enough funds to make it happen.
A solution isn’t likely to come within the next decade, Neuzil said, and could take closer to 30 or 40 years. “As antsy as people may feel about wherever this gets buried, the reality is the stuff is sitting on site in any number of places and usually in places you might think of as vulnerable,” he said. “It really is [in] everybody’s best interest that this be done as expeditiously as possible. Which is probably not going to happen anytime soon.”

50 Cities with Terrible Air Pollution

If you live in any one of a number of cities in Bulgaria or Poland, you may be breathing in some of the worst air pollution in Europe, according to new data from the European Environment Agency (EEA). But it’s not just those two countries. People across the continent are inhaling bad air.
“More than 90 percent of Europe’s urban citizens are exposed to levels of air pollution that are well above the World Health Organization’s advised guidelines,” Hans Bruyninckx, EEA’s executive director said, explaining the data. “And this has serious effects on citizens’ quality of life.”
The EEA looked at nearly 400 cities in the European Union and measured four different types of pollution: sulfur dioxide, ozone, nitrogen dioxide and PM10, a harmful type of particulate matter. Focusing on PM10 — the worst for humans of the quartet — the slideshow above ranks the top 50, from best (or maybe we should call it least bad) to worst.
Pernik, a town of about 80,000 people in west-central Bulgaria, fared the worst of any place. The EEA report considered the average number of days in a year each city exceeded a certain threshold. In the case of PM10, it’s 50 micrograms per cubic meter of air, and a city should only exceed that 35 days per year, according to the European Commission’s Air Quality Standards. Pernik had 180 days beyond that target level.
Three other Bulgarian towns and one village in Poland rounded out the top five. Five additional Polish towns completed the top 10.
“Even at concentrations below current air quality guidelines, particulate matter poses a health risk,” states the EEA’s “Air Quality in Europe – 2013 Report.” Inhalation and penetration into the lungs and bloodstream can lead to “respiratory, cardiovascular, immune, and neural systems” problems. In addition, it can lead to lung cancer. “Mortality associated with air pollution is about 15 to 20 percent higher in cities with high levels of pollution compared to relatively cleaner cities,” according to the report.
Many of the better-known European cities, while on the list, were much lower. Paris, for example, averaged 14.5 days beyond the target. Madrid saw 6.7 days, Glasgow saw 2 and Edinburgh saw none.
So why the discrepancy, with the majority of pollution in just a few countries? “The chemical composition of particulate matter is quite different across Europe,” EEA’s Peder Gabrielsen told Weather.com. “In terms of PM10, we generally see more PM10 limit value exceedances in eastern Europe compared to western Europe.”
Though the numbers are, believe it or not, better than in the past, there’s still work to be done. Bruyninckx put the onus on EU countries and people. “Member states should better implement the EU policies that already exist,” he said. “But I would also say that lifestyle choices of individual citizens and families are important. For example the transport and mobility choices you make.”
