Climate change brings a boom in jellyfish, and a threat to nuclear reactors

Is climate change beating nuclear reactors, even while the nuclear lobby claims it’s the other way around? There are many records of nuclear reactors being shut down due to jelly fish.

Jellyfish are causing mayhem as pollution, climate change see numbers boom, ABC, RN  By Hong Jiang and Sasha Fegan for Late Night Live 6 Jan 19 Jellyfish have been around for at least 500 million years — they’re older than dinosaurs and even trees.Science writer Juli Berwald calls them “ghosts from the true garden of Eden”.

“An intelligence of a sort has allowed them to make it through the millennia,” she says.

And they’re not going anywhere.

In fact, the brainless, spineless, eyeless, bloodless creatures are booming in numbers — and causing mayhem around the world. Their propensity to breed fast and prolifically means jellyfish can disrupt ocean ecosystems in a flash.

And their effects aren’t contained to the sea.

In places like Sweden, Israel, the US and the Philippines, power plants have been affected by blooms of jellyfish.

“So many jellyfish were swept into the power system … that it shut down the power system through much of this one island in the Philippines,” Ms Berwald says. People thought that perhaps there was a coup going on, but there wasn’t, it was just the jellyfish.”

Jellyfish have also caused plants to shut down in Japan.

“One jellyfish scientist from Japan told me that the first threat to the electric system in Japan is earthquakes, but the second is jellyfish,” Berwald says.

“We are dealing with a ubiquitous creature.”

A human cause

Some scientists think jellyfish numbers are increasing as the climate changes — the creatures reproduce well in warmer waters.

Jellyfish also fare better than many other sea creatures in polluted waters, as they don’t need much oxygen.

Berwald says that can give them the upper hand over predators.

“They can sort of slip into polluted waters, into low oxygen waters, and hide from predation there better than a fish that has a higher oxygen demand,” she says…….. https://www.abc.net.au/news/2019-01-06/the-magic-and-mayhem-of-jellyfish/10377112

Donald Trump should negotiate with Kim Jong-un, who may be willing to limit nuclear production capability

North Korea may be willing to begin denuclearization, and Donald Trump should make a deal. https://www.usatoday.com/story/opinion/2019/01/04/kim-jong-un-north-korea-donald-trump-denuclearization-offer-column/2473360002/ Michael O’Hanlon,   Jan. 4, 2019

Kim Jon-Un indicated he would put nuclear production capability on the table as a bargaining chip, and Donald Trump should make that deal.

In his traditional New Year’s Day speech earlier this week, North Korean strongman leader Kim Jong-Un has just made an offer that, if serious, could present an opportunity for President Donald Trump to reach a historic breakthrough in the nuclear crisis on the Korean peninsula and record his greatest foreign-policy accomplishment as president.

Kim’s speech was not all sweetness and light. He warned that his patience is not infinite, and that in the absence of diplomatic progress, his country may resort to more confrontational tactics. Little has happened since the famous Singapore summit back in June between Kim and Trump; we seem no closer to a deal on North Korea’s threatening military capabilities now than we did six months ago. Meanwhile, Kim clearly resents and suffers from the tough international sanctions that the Trump administration has convinced the United Nations to impose these last two years, after North Korea’s big missile and nuclear tests of 2017. The latest statistics show that, despite sanctions evasion in multiple quarters, North Korean trade was down as much as half in 2018 compared to the year before.

But Kim held out an olive branch nonetheless. He seems to want a deal, and seems interested in another summit. He was much more specific than ever before about what he might offer in the course of such a tete-a-tete with Trump. So far, North Korea has only offered to place a moratorium on future nuclear and long-range missile tests, which has been a welcome development, but has only talked vaguely about “denuclearization” and has not stopped making more bombs. Now, apparently, Kim would put nuclear production capability on the table as a bargaining chip.

North Korea experts like Jonathan Pollack and Jung Pak have documented how unlikely Kim would be to give up all his nuclear bombs (U.S. intelligence estimates he has as many as 60 by now). They represent the collective accomplishments of a program that Kim’s grandfather and father prioritized when they led North Korea, so giving up all those bombs quickly would almost seem to dishonor the memory and legacy of his forefathers. And perhaps even more importantly, Kim as well as his generals remember the one cardinal mistake Saddam Hussein, Mohammar Quadhafi, and the Taliban all committed — leaving themselves vulnerable in war against the United States because of the lack of a nuclear deterrent. For Kim to give up the bomb, he would need a great deal of confidence that relations will remain peaceful.

There is an opportunity to compromise, relax

Yet there is still a big opportunity for compromise, if Kim is serious about ending production of more bombs. North Korea could stop expanding its nuclear arsenal, and we could relax, then lift some of the sanctions imposed on North Korea over the years, especially the U.N. sanctions that have really cut into North Korean trade with China and South Korea in the last couple years. The goal of complete denuclearization could await another day.

With this approach, the United States would keep enough sanctions in place to stay true to its principle that North Korea cannot be accepted as a nuclear-weapons state; before being fully welcomed into the community of nations, it will in fact have to honor its obligations under the Nuclear Non-Proliferation Treaty and give up all its bombs. Yet as a practical matter, that second stage of nuclear talks can wait for a number of months or years. That is ok. The world will be much safer if North Korea stops enlarging and improving its nuclear and long-range missile arsenals that could threaten not only South Korea and Japan (and the almost 300,000 Americans living in those two countries combined), but also eventually North America.

Trump should take what he can get for now

The real challenge is likely to be verification. We know where some, but not all, of North Korea’s nuclear infrastructure is located. As such, international inspectors would have to be allowed to return not only to the Yongbyon location where they have been before, and where North Korea has operated a nuclear reactor to make plutonium as well as centrifuges to enrich uranium. They would also need some degree of free reign to explore other suspicious sites around the country. On the one hand, this would not be an arrangement unique to North Korea; similar provisions are part of the Iran nuclear deal, for example. On the other hand, North Korea has shown extreme nervousness about such inspections in the past.

Another possible problem: John Bolton, Trump’s national security advisor, and Secretary of State Mike Pompeo may consider a deal that only freezes, rather than eliminates, North Korea’s nuclear arsenal inadequate for purposes of American and allied security. But they should reassess, or Trump should overrule them.

This compromise deal would go further than the Iran deal, in fact, if North Korea were willing to see its nuclear production facilities dismantled permanently. Yes, Kim would keep his nukes for a while. But he would have powerful economic and military reasons to behave himself. In this case, taking half a loaf is far more realistic than hoping for a complete denuclearization accord that just isn’t in the cards anytime soon. We should immediately engage in serious talks to see just how serious Kim really is about this intriguing and promising offer.

Renewables beating coal energy in Germany

Renewables have overtaken coal as Germany’s main energy source, World Economic Forum, Reuters Staff, 4 Jan 2019  Renewables overtook coal as Germany’s main source of energy for the first time last year, accounting for just over 40 percent of electricity production, research showed on Thursday.

The shift marks progress as Europe’s biggest economy aims for renewables to provide 65 percent of its energy by 2030 in a costly transition as it abandons nuclear power by 2022 and is devising plans for an orderly long-term exit from coal.

The research from the Fraunhofer organisation of applied science showed that output of solar, wind, biomass and hydroelectric generation units rose 4.3 percent last year to produce 219 terawatt hours (TWh) of electricity. That was out of a total national power production of 542 TWh derived from both green and fossil fuels, of which coal burning accounted for 38 percent.

Green energy’s share of Germany’s power production has risen from 38.2 percent in 2017 and just 19.1 percent in 2010.

Bruno Burger, author of the Fraunhofer study, said it was set to stay above 40 percent this year.

“We will not fall below the 40 percent in 2019 because more renewable installations are being built and weather patterns will not change that dramatically,” he said……….https://www.weforum.org/agenda/2019/01/renewables-overtake-coal-as-germanys-main-energy-source?utm_source=Facebook%20Videos&utm_medium=Facebook%20Video

New Mexico could get more nuclear waste, and perhaps high level nuclear waste

More nuclear waste could come to New Mexico, Santa Fe New Mexican, By Rebecca Moss | rmoss@sfnewmexican.co, Jan 5, 2019 

       In the final days of Republican Gov. Susana Martinez’s administration, the state Environment Department approved a controversial change to how federal officials measure the amount of nuclear waste buried some 2,000 feet underground in Southern New Mexico salt beds.

Proponents of the change say it merely clarifies that the storage site will measure the actual volume of transuranic waste deposited there rather than the volume of the massive exterior waste drums, called overpack containers — and the air inside. But critics say the result will be an increase in the quantity of material stored at the U.S. Department of Energy’s Waste Isolation Pilot Plant near Carlsbad.

Several nuclear watchdog groups, which say they intend to appeal the decision, also fear the change in WIPP’s hazardous waste permit from the state could open the door to allowing high-level nuclear waste to be brought into New Mexico.

It’s unclear whether the Democratic administration of Gov. Michelle Lujan Grisham, who took office last week, will support the Environment Department’s decision in December or take any action to overturn it. The governor hasn’t yet appointed a Cabinet secretary to lead the Environment Department.

Tripp Stelnicki, a spokesman for Lujan Grisham, said the administration will be reviewing the potential impacts of the modification. But, Stelnicki said in an email, “that’s the case for all of the prior administration’s decisions.”

The governor “certainly recognizes safety at WIPP, for the public and for workers, is utterly paramount,” he added. “Safety is the expectation and that expectation will guide decision-making.”

Under the Land Withdrawal Act of 1992, Congress limited WIPP’s capacity to 6.2 million cubic feet, or just over 175,500 cubic meters. The plant, now about 52 percent full, is the only permanent repository for nuclear waste in the nation.

The 1992 law also limits the type of nuclear material that can be stored at the underground facility.

Under WIPP’s hazardous waste permit from the state, the volume of material stored at the plant has been measured based on the size of each exterior waste container.

Last year, however, the Department of Energy and Nuclear Waste Partnership LLC, a private company that operates the plant, told the New Mexico Environment Department the permit should be altered because it was forcing them to overcalculate the amount of waste at WIPP. Language in the permit required them to count empty space in large packing containers used to store smaller waste vessels — like hulking Russian nesting dolls. …….

Still, critics believe the waste measurement change — after nearly 20 years of consistent measurement procedures — is a thinly veiled effort to expand the size and mission of WIPP.

“It was the wrong way to go,” said Steve Zappe, who testified at the Carlsbad hearing. Zappe spent 17 years working on WIPP for the state Environment Department and helped craft the plant’s original waste permit.

The permit modification, he said, was allowing the Department of Energy to redefine how much nuclear waste it can dispose of at WIPP without going through Congress………. http://www.santafenewmexican.com/news/local_news/more-nuclear-waste-could-come-to-new-mexico/article_83a78c54-7579-5a43-8285-3ebe024758da.html

UK’s legal battle over botched handling of the Magnox nuclear decommissioning contract.

Former chiefs of UK’s nuclear body launch legal action over Magnox fiasco  http://www.cityam.com/271148/former-chiefs-uks-nuclear-body-launch-legal-action-over, Jessica Clark, 5 Jan 19
Jess Clark is a City A.M. news reporter covering private equity and investment. The former bosses of the UK’s nuclear body are caught in a legal battle over an investigation into the botched handling of the Magnox nuclear decommissioning contract. The former chairman of the Nuclear Decommissioning Authority (NDA) Stephen Henwood and the organisation’s former chief executive John Clarke are trying to block the publication of a critical report into the contract, which cost the taxpayer £120m, Sky News reported.

Former National Grid chief executive Steve Holliday completed an independent inquiry into the handling of the contract several months ago, however Henwood and Clark have raised objections to Holliday’s process.

Sky News reported that the pair sought an injunction before Christmas to stop the report being submitted to government.

The £6.1bn Magnox contract, which was awarded to the Cavendish-Fluor Partnership in March 2014, related to the clean-up of 12 nuclear sites across the UK.

The procurement process was challenged in the High Court by another bidder alleging that the NDA had broken the rules, and two years later the court ruled that the NDA has “committed multiple, manifest errors in evaluating the (losing) RSS bid and the (winning) CFP bid”, according to Holliday’s interim report.

A National Audit Office report also found that the NDA’s “fundamental failures in the Magnox contract procurement raise serious questions about its understanding of procurement regulations and its ability to manage large, complex procurements.”

Closer inspection of Peach Bottom nuclear plant following violation notice

Peach Bottom nuclear plant issued violation notice, will come under closer scrutiny from regulators https://lancasteronline.com/news/local/peach-bottom-nuclear-plant-issued-violation-notice-will-come-under/article_a147a194-105e-11e9-8b99-a32817bc8be2.htmlAD CRABLE | Staff Writer, Jan 4, 2019 

      The Peach Bottom nuclear plant will come under closer inspection from federal regulators following damage to an emergency diesel generator during a test in June.

The U.S. Nuclear Regulatory Commission said Peach Bottom owner Exelon committed a violation in the low to moderate safety range for the incident.

The violation notice comes after plant staff and NRC regulators twice found problems on one of the four generators. The problems were fixed but during a test of the generator in June, a fit pin became dislodged and damaged compressor blades. Debris from the blades contaminated other parts of the generator, the NRC said.

The NRC said that “Exelon failed to take adequate corrective actions to address the adverse conditions involving the (generator), leading to the problems that surfaced on June 13.

The violation means that the NRC will focus more scrutiny on Peach Bottom. The agency will perform an inspection at the plant in coming months to review the company’s root-cause evaluation of the issues and any corrective actions, the NRC said.

Exelon did not contest the findings.

Exelon has asked the NRC for permission to extend the license of the York  County nuclear plant for 20 years, to 2053 and 2054 for its two units.

The NRC is reviewing the request.

Historical cooling periods are still playing out in the deep Pacific

 https://www.eurekalert.org/pub_releases/2019-01/hjap-hcp010419.php4 Jan 19, Whereas most of the ocean is responding to modern warming, the deep Pacific may be cooling, HARVARD JOHN A. PAULSON SCHOOL OF ENGINEERING AND APPLIED SCIENCES The ocean has a long memory. When the water in today’s deep Pacific Ocean last saw sunlight, Charlemagne was the Holy Roman Emperor, the Song Dynasty ruled China and Oxford University had just held its very first class. During that time, between the 9th and 12th centuries, the earth’s climate was generally warmer before the cold of the Little Ice Age settled in around the 16th century. Now, ocean surface temperatures are back on the rise but the question is, do the deepest parts of the ocean know that?

Researchers from the Woods Hole Oceanographic Institution and Harvard University have found that the deep Pacific Ocean lags a few centuries behind in terms of temperature and is still adjusting to the advent of the Little Ice Age. Whereas most of the ocean is responding to modern warming, the deep Pacific may be cooling.

The research is published in Science.

“Climate varies across all timescales,” said Peter Huybers, Professor of Earth and Planetary Sciences in the Department of Earth and Planetary Sciences and of Environmental Science and Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences and co-author of the paper. “Some regional warming and cooling patterns, like the Little Ice Age and the Medieval Warm Period, are well known. Our goal was to develop a model of how the interior properties of the ocean respond to changes in surface climate.”

What that model showed was surprising.

“If the surface ocean was generally cooling for the better part of the last millennium, those parts of the ocean most isolated from modern warming may still be cooling,” said Jake Gebbie, a physical oceanographer at Woods Hole Oceanographic Institution and lead author of the study.

The model is a simplification of the actual ocean. To test the prediction, Gebbie and Huybers compared the cooling trend found in the model to ocean temperature measurements taken by scientists aboard the HMS Challenger in the 1870s and modern observations from the World Ocean Circulation Experiment of the 1990s.

The HMS Challenger, a three-masted wooden sailing ship originally designed as a British warship, was used for the first modern scientific expedition to explore the world’s ocean and seafloor. During the expedition from 1872 to 1876, thermometers were lowered into the ocean depths and more than 5,000 temperature measurements were logged.

“We screened this historical data for outliers and considered a variety of corrections associated with pressure effects on the thermometer and stretching of the hemp rope used for lowering thermometers,” said Huybers.

The researchers then compared the HMS Challenger data to the modern observations and found warming in most parts of the global ocean, as would be expected due to the warming planet over the 20th Century, but cooling in the deep Pacific at a depth of around two kilometers depth.

“The close correspondence between the predictions and observed trends gave us confidence that this is a real phenomenon,” said Gebbie.

These findings imply that variations in surface climate that predate the onset of modern warming still influence how much the climate is heating up today. Previous estimates of how much heat the Earth had absorbed during the last century assumed an ocean that started out in equilibrium at the beginning of the Industrial Revolution. But Gebbie and Huybers estimate that the deep Pacific cooling trend leads to a downward revision of heat absorbed over the 20th century by about 30 percent.

“Part of the heat needed to bring the ocean into equilibrium with an atmosphere having more greenhouse gases was apparently already present in the deep Pacific,” said Huybers. “These findings increase the impetus for understanding the causes of the Medieval Warm Period and Little Ice Age as a way for better understanding modern warming trends.”
