The six U.S. nuclear power plants most likely to shut down

The six U.S. nuclear power plants most likely to shut down

Sandia National Laboratories

Three Mile Island: still not popular.

The nuclear power industry is melting down in America, and in the rest of the Western Hemisphere too.

Nuclear plants still generate nearly 20 percent of electricity in the U.S. But a report by investment research firm Morningstar in its latest Utilities Observer publication warns about the sector’s risks. The report says “the ‘nuclear renaissance’ is on hold indefinitely” in the West thanks to low electricity prices, largely driven by the natural-gas fracking boom but also by new renewable energy projects, and controversy in the wake of the Fukushima meltdown:

Aside from the two new nuclear projects in the U.S., one in France (Flamanville), and a possible one in the U.K. (Hinkley Point C), we think new-build nuclear in the West is dead. …

We don’t expect an end to the new nuclear construction in China and South Korea or the development interest in India and elsewhere in Asia. … Nuclear power is not going to disappear as a long-term option and it will continue to evolve. However, an investment in a new Western nuke plant even with the best available technology today will remain a rare experiment.

Another problem for the sector: Nuclear power plants are ill-suited to modern energy-pricing schemes, as The New York Times recently reported. Nuclear plants can’t be quickly powered up or down to meet demand as prices rise and fall throughout the day and night, so sometimes reactor operators are forced to sell electricity at a loss when demand is lowest. 

Five U.S. nuclear power plants have recently shuttered or announced upcoming closures: Vermont Yankee in Vermont, San Onofre in California, Kewaunee in Wisconsin, Crystal River in Florida, and Oyster Creek in New Jersey. Those closures have been largely the result of falling power prices and rising maintenance costs.

Here are six more nuclear plants that Morningstar identifies as the most likely to close next:

1. & 2. R.E. Ginna, opened in 1984 in Onatario, N.Y., and James A. FitzPatrick, opened in 1974 in Scriba, N.Y.

Blame it on the wind. “Renewable energy has flooded the wind-rich region, driven by New York’s renewable portfolio standard,” the Morningstar report notes. “Upstate New York off-peak power prices have fallen to $32 per megawatt hour as of mid-2013 from $55/MWh in 2008. Transmission bottlenecks prevent the plants from tapping the state’s eastern markets, where power prices are 30% higher.”

3. Pilgrim, opened in 1972 in Plymouth, Mass.

The power plant’s operating license was extended until 2032 despite fierce opposition last year. Still, says Morningstar, “Entergy is not obligated to operate it for that long and could exit if power prices sink much further.”

4. Three Mile Island, opened in 1974 in Middletown, Penn.

One of Three Mile Island’s two reactors closed down in 1979 because, well, because it partially melted down. Now Morningstar says the other reactor is at risk of closure because it “faces challenging economics,” and those challenges will be exacerbated if several large natural-gas plants are built nearby as proposed.

5. Davis Besse, opened in 1977 in Oak Harbor, Ohio

Morningstar notes “strong opposition” to efforts to extend the power plant’s operating license after it expires in 2017 and the plant’s “tarnished reputation.” The facility closed in 2002 after corrosion was discovered in the main vessel and it didn’t resume operations until 2004. Still, U.S. Nuclear Regulatory Commission staff declared in September that there were no safety issues at the plant that would affect its relicensing effort.

6. Indian Point, opened in 1973 in Buchanan, N.Y.

Neighbors and many lawmakers really want to shut down this plant, located less than 50 miles north of Manhattan. “When you have this much local opposition and opposition from state government, what I’ve seen over time is that it’s very difficult to operate plants,” former U.S. Nuclear Regulatory Commissioner Michael Jaczko told Bloomberg in October. “The best solution is to sit down with all the interested stakeholders and think about a way to shut down the plant on a reasonable time frame.” Still, Morningstar’s analysts say that “owing to transmission constraints and Indian Point’s relatively low cost, we think there is a strong probability that the plant will eventually be relicensed.”

Maybe somebody should tell James Hansen about the nuclear industry’s mounting woes.

Bangladesh’s biggest power plant will harm world’s biggest mangrove forest

Bangladesh’s biggest power plant will harm world’s biggest mangrove forest

lepetitNicolas

Burning coal is a surefire way of damaging the climate, and harming mangroves is a surefire way of worsening climate impacts. Which makes the planned construction of Bangladesh’s largest coal-fired power plant at the edge of the world’s biggest mangrove forest doubly troubling.

Construction is beginning on the 1,320-megawatt Rampal power plant less than 10 miles from the Sundarbans, the sweeping mangrove system that straddles Bangladesh and India, helping to protect an eastern chunk of the Subcontinent from floods and cyclones.

An estimated 20,000 people recently marched to protest the project. Scientists warn it will produce pollution that feeds acid rain over the mangroves and suck up vast quantities of the ecosystem’s water.

The Bangladeshi government says the plant is needed as part of an effort to ease blackouts and help half the nation’s population access electricity supplies for the first time. But when it comes to the plant’s environmental impacts, government officials are stuck in obstinate-denier mode. They say the plant will be built using “the latest ultra super critical technology” and burn “high-quality imported coal” meaning that it “would not affect the environment of Sundarban.” Yeah, right. From an article in e360:

The construction of the Rampal plant is part of an ambitious government strategy to increase electricity generation to 20,000 megawatts by 2021 — a goal that relies heavily on coal. The current administration of Prime Minister Sheikh Hasina is proposing a dozen new coal plants, with more likely to come. Until recently, less than five percent of Bangladesh’s electricity production came from coal. Instead the country produced most of its energy from natural gas and biomass.

Critics of the Rampal plant and the country’s growing embrace of coal argue that it is a reckless strategy for a nation that is consistently rated as one of most vulnerable countries to global warming. Few nations are as low-lying as Bangladesh, and the Sundarbans is one of the country’s most important bulwarks against rising seas and intensifying typhoons and other extreme weather events.

Bangladesh endures frequent cyclones and, with much of the country laying less than five yards above sea level, it frequently floods — with deadly results. Bangladeshis deserve access to electricity, but they don’t deserve this filthy project. There are much better ways.

Unregulated bumblebee trade threatens bumblebees

Unregulated bumblebee trade threatens bumblebees

Dan Mullen

Though they’re bigger, bumblebees tend to get overshadowed by European honeybees. We’ve all heard that honeybee colonies are collapsing, but did you know that the bumblebees that been have been pollinating America’s native plants for millennia are also disappearing?

The U.S. government, though, treats them with equal disdain. It is not taking decisive steps to protect honeybees, and no one’s yet been able to sting it into action to protect the bumbling variety either.

Still, activists keep trying. On Tuesday, the Natural Resources Defense Council, Defenders of Wildlife, and the Xerces Society for Invertebrate Conservation wrote to Agriculture Secretary Tom Vilsack, urging the USDA’s Animal and Plant Health Inspection Service to regulate commercial trade in bumblebees.

Commercial operations box up bumblebees and ship them around the country, generally to pollinate crops grown in greenhouses. That trade is transmitting deadly diseases and parasites to wild populations, the enviros charge, and the release of aggressive Eastern species of bumblebees in Western states is hurting populations of the chilled-out Western varieties.

It’s not like this is a new issue. APHIS has known about problems associated with the bumblebee trade for at least two decades. And the environmentalists submitted a petition urging the agency to regulate the commercial bumblebee trade nearly four years ago. From the activists’ letter [PDF]:

The requested rulemaking is urgent and overdue. Numerous bumble bee pollinators have already declined dramatically and pathogens from commercial bumble bees are likely responsible for this; without agency intervention, we will likely continue to see a dramatic decline in bumble bee pollinators with perilous and potentially irreversible consequences. …

In the last two decades, there has been a dramatic rise in the demand for commercially reared bumble bees to pollinate greenhouse crops, particularly tomatoes. This rise has come with a concomitant decline in numerous species of North American bumble bees. The evidence to date supports the hypothesis that this decline was caused by the introduction of diseases spread by commercial bees. Since we submitted our petition in January 2010 several new studies have shown that commercial bumble bee hives harbor disease.

The unregulated bumblebee trade, combined with the wanton use of pesticides, is thought to have already killed off the Franklin’s bumblebee, which was last spotted in 2006. The environmentalists say federal guidelines could help save the western bumblebee, rusty patched bumblebee, yellow-banded bumblebee, and American bumblebee from succumbing to the same fate.

Cloudsourcing: Power Clouds Takes New Approach to Solar Energy

When it comes to providing energy, a Singapore-based company has its head in the clouds. And they’re hoping it will revolutionize the way energy systems are developed.

Power Clouds is building large-scale solar parks and commercial rooftop energy plants to harness power for remote regions of the world. Beginning with three solar parks in Scornicesti, Romania, the company put its first plant into operation in August, with the third plant scheduled to go into operation in December. Attilio Palumbo, project manager for Power Clouds, says they chose that region based on several factors.

“[We looked at] the country’s social and economic stability, geographical characteristics, weather conditions, the country’s economic support and the population’s energy demand,” he says. “We will soon officially announce the locations of the fourth and fifth plants that will be built.”

In addition to harnessing energy for the region, the company’s unique business model invites outside individuals to become a part of the solution. The solar panels for each project are purchased by outside companies or individuals, who buy a panel (or “cloud”) for $1,200 under a hire-purchase contract. The panel is installed in the solar park, and when the plant becomes operational, the purchaser receives a monthly check from Power Clouds, which essentially rents back the panel from the purchaser.

The agreement lasts for 20 years, and Palumbo claims that, during that time, they will receive back about 400 percent of their initial purchase price.

“The economic returns begin the moment the solar plant goes into operation,” he explains. “Over the first five years, people [recoup] the amount spent on the panel’s purchase, and continue to receive monthly returns for the next 15 years after that.”

He says the monthly revenue generated consists of a fixed fee plus a variable amount based on each plant’s actual energy production. Each solar park takes less than four months to complete, and he says panel purchasers for the inaugural solar park are already receiving financial returns.

Fukushima keeps on leaking, Japan keeps on issuing confusing explanations

Fukushima keeps on leaking, Japan keeps on issuing confusing explanations

Oh, fuk … ushima.

Problems continue to burble up at Japan’s crippled Fukushima nuclear power plant — or, in this case, gush out.

We learned last month that contaminated water has been leaking from the plant into the sea at a rate of about 300 tons a day. Then last week came word of a more serious spill of 300 tons of extremely radioactive water, which the government classified as a level 3 incident on the International Nuclear and Radiological Event Scale.

The scale runs from zero, where everything is peachy, past level 3, which indicates a “serious incident,” up to level 7, which means the kind of living hell that engulfed the facility when its reactors melted down following an earthquake and tsunami in 2011.

From CNN:

The decision to issue the level 3 alert came two days after a Japanese government minister had compared the plant operator’s efforts to deal with worrying toxic water leaks at the site to a game of “whack-a-mole.”

Now the International Atomic Energy Agency wants to know why last week’s spill received an incident rating while other accidents at the site over the past two years — from a rat-induced cooling outage to seemingly endless radioactive spills — received none. The IAEA says Japan should avoid sending “confusing messages.”

Meanwhile, Japan is forging ahead with plans to allow utilities to begin firing back up their nuclear power plants, which were all shut off in the wake of the Fukushima meltdown. What could go wrong?

“Bee-friendly” plants could be bee killers

“Bee-friendly” plants could be bee killers

Be a friend to a bee and be wary of “bee-friendly” products.

Beware of buying “bee-friendly” plants — they might end up killing your friendly backyard bees.

As gardeners have been waking up to the pollinator crisis, many have been planting bee-friendly veggies and flowers and keeping neonicotinoid insecticides away from their plots. But some plants being marketed to these bee-loving gardeners could actually be harmful to pollinators, according to a new report.

Friends of the Earth and the Pesticide Research Institute bought 13 “bee-friendly” nursery plants from Home Depot, Lowe’s, and Orchard Supply Hardware in three American regions and found that seven of them were contaminated with neonic insecticides, which have been implicated in worldwide bee declines. Some plants contained two types of neonics. A sunflower plant purchased in Minnesota tested positive for three of them.

Such insecticides are so harmful to pollinators that they are being banned in Europe. Reps. Earl Blumenauer (D-Ore.) and John Conyers (D-Mich.) introduced legislation last month that would impose a similar ban here — the Save America’s Pollinators Act [PDF] — but it won’t be going anywhere in the GOP-dominated House.

How did so many neonics end up in “bee-friendly” plants? “There are very few insecticide products containing multiple neonicotinoids as active ingredients and none containing three different neonicotinoids, so these plants were possibly treated multiple times during their short lifespan,” says the report. Indeed, the nursery industry is virtually swimming in pest-killing poisons. The report notes that such pesticides are used at higher volumes on nursery plants than on agricultural crops, and that they can persist from one season to another:

Nurseries commonly apply neonicotinoids as soil injections, granular or liquid soil treatments, foliar sprays (applied to leaves), and seed treatments. Water-soluble pesticides such as neonicotinoids are readily absorbed by plant roots and transported systemically in the plant’s vascular system to other portions of the plant, including roots, pollen, leaves, stems, and fruit. This systemic action results in the exposure of beneficial, non-target insects such as bees to potentially lethal doses of neonicotinoids.

Friends of the Earth, Pesticide Action Network, The Xerces Society, and other nonprofits are sending letters [PDF] and signed petitions to Lowe’s, Home Depot, Target, and other garden retailers asking them to stop selling neonics and plants that have been pre-treated with the pesticides.

So how can you protect your garden from neonics when even “bee-friendly” plants are loaded with them? Experts say get back to basics or go organic. “Gardeners should start their plants from seeds that have not been treated with chemicals, or choose organic plants for their gardens,” said Pesticide Action Network spokesman Paul Towers.

Can an ice wall stop Fukushima radiation from leaking into the sea?

Can an ice wall stop Fukushima radiation from leaking into the sea?

The Fukushima ice wall would not look anything like this.

It’s been almost two and a half years since the meltdown at the Fukushima nuclear plant and the place is still a huge, scary mess.

Here’s how The New York Times introduced this week’s grim news from the plant:

First, a rat gnawed through exposed wiring, setting off a scramble to end yet another blackout of vital cooling systems at the Fukushima Daiichi nuclear plant. Then, hastily built pits for a flood of contaminated water sprang leaks themselves. Now, a new rush of radioactive water has breached a barrier built to stop it, allowing heavily contaminated water to spill daily into the Pacific.

It turns out that radioactive water has been spilling into the sea almost since the initial disaster, at a rate of 75,000 gallons, or 300 tons, a day.

So now Tokyo Electric Power Company, or TEPCO, which owns the plant, has a plan to build an underground wall of frozen earth to stop the radioactive water leakage. NPR explains:

[T]o understand, you need to know the geography of Fukushima. There are three melted down reactors, and they’re all right on the coast. To the west, you have mountains. To the east, you have ocean. And so what’s happening is groundwater flows downhill. It flows down through the ruins of the plant and then flows out to the sea. …

So now, TEPCO has proposed literally creating a wall of ice around the plant. And what they’re talking about is not a wall above ground, but freezing the ground around the plant to stop water from flowing in. …

So the basic idea is that they run piping into the ground and they put coolant in the piping and that freezes the earth around the pipes, and it all sort of gradually forms together into a wall. This is something that civil engineers see sometimes, but it’s not that common. And certainly, the way they’re talking about using it in Fukushima is unprecedented. This wall will be nearly a mile around according to TEPCO. It would require more than 2 million cubic feet of soil to be frozen. But if it worked, then it may be the only way to keep water from flowing into the plant and contaminated water from flowing out.

The New York Times points out another challenge: “the wall will need to be consistently cooled using electricity at a plant vulnerable to power failures. The original disaster was brought on by an earthquake and tsunami that knocked out electricity.”

Japanese Prime Minister Shinzo Abe, fed up with continued ineptitude and deception from TEPCO, said this week that his government will get involved in the cleanup. It’s not clear what that involvement will look like, but it may include helping to fund the frozen wall — no small thing, as it’s expected to cost between $300 million and $400 million.

Wild thing, I think I need you: How weeds could save dinner

Wild thing, I think I need you: How weeds could save dinner

Kim Hummer / USDA

This wild species of strawberry was recently discovered growing in the Oregon Cascades. Researchers say it could be bred with other species to create new disease-resistant or delicious varieties.

Who needs weeds? In a climate-changed world, we all do.

Wild relatives of potatoes, peas, eggplants, and lentils, among many other crops, are often thought of as weeds, but they could help us produce healthier harvests even as we face water shortages and other climate-induced challenges.

Nature explains:

Faced with climate change, plant breeders are increasingly turning to the genomes of the wild, weedy relatives of crops for traits such as drought tolerance and disease resistance. But a global analysis of 455 crop wild relatives has found that 54% are underrepresented in gene bank collections — and that many, including ones at risk of extinction, have never been collected.

The findings, released on 22 July by the International Center for Tropical Agriculture (CIAT), based near Palmira, Colombia, will guide the largest international initiative to date to conserve crop wild relatives. The effort, which is being spearheaded by the Global Crop Diversity Trust, based in Rome, in partnership with the Millennium Seed Bank of London’s Kew Gardens, is deemed urgent at a time when one in five plants faces extinction.

Plant breeders are keenly interested in securing the genetic diversity needed to breed new varieties that will withstand the droughts and elevated temperatures expected in the future as a result of climate change. Crop wild relatives are one of the most valuable genetic resources to improve crops, but they are threatened because of habitat loss as well as gene flow from domesticated plants through cross-pollination, says Paul Gepts, a plant breeder at the University of California, Davis.

Here’s one sweet example of how wild plants can help shore up food supplies: This newly discovered strawberry species, if crossed with other varieties, “may reveal new flavors or genetic disease resistance,” says Kim Hummer, a scientist with the USDA Agricultural Research Service.

California’s San Onofre nuclear plant gets final death blow

California’s San Onofre nuclear plant gets final death blow

San Onofre nuclear plant — now just a blight on the seashore.

Southern California Edison is officially giving up on the San Onofre nuclear power plant — and it’s about time. When workers have to resort to masking tape and broomsticks to patch up a leaky pipe, you know things are bad. And that’s just one of many reasons why the name of the plant is usually preceded by the word “troubled.”

Speaking of which, from CBS News:

The troubled San Onofre nuclear power plant on the California coast is closing after an epic 16-month battle over whether the twin reactors could be safely restarted with millions of people living nearby, officials announced Friday.

Operator Southern California Edison said in a statement it will retire the twin reactors because of uncertainty about the future of the plant, which faced a tangle of regulatory hurdles, investigations and mounting political opposition. With the reactors idle, the company has spent more than $500 million on repairs and replacement power.

From the Los Angeles Times:

The coastal plant near San Clemente once supplied power to about 1.4 million homes in Southern California but has been shuttered since January 2012 when a tube in its newly replaced steam generators leaked a small amount of radioactive steam, leading to the discovery that the tubes were wearing down at an unusual rate.

That’s a different leak than the one patched with masking tape, just so you know.

Anti-nuclear activists are psyched. “The people of California now have the opportunity to move away from the failed promise of dirty and dangerous nuclear power and replace it with the safe and clean energy provided by the sun and the wind,” said Erich Pica, president of Friends of the Earth U.S.

This leaves just one operating nuke plant in California — Diablo Canyon, near San Luis Obispo. Last year it was knocked offline by a jellyfish-like sea critter, but most of the time there’s nothing to worry about — other than the fact that the plant sits near two active earthquake faults.
