New research highlights need for international standards to safeguard against plutonium ”hot” particles.

New study delves into issues relating to soils around Maralinga region,  https://www.portlincolntimes.com.au/story/7262167/study-shows-radioactive-particles-from-nuclear-testing-persist-at-maralinga, Luca Cetta,  

A new study has highlighted the first international standards needed to safeguard against contamination from nuclear testing, and a Kokatha Elder says the impact of nuclear testing at Maralinga cannot be forgotten.

More than 100 kilograms of highly toxic uranium and plutonium was dispersed in the form of tiny ‘hot’ radioactive particles after nuclear tests were conducted by the British in remote areas of South Australia, including Maralinga.

Scientists have new evidence these radioactive particles persist in soils to this day, more than 60 years after the detonations.

The British detonated nine nuclear bombs and conducted nuclear tests in South Australia between 1953 and 1963.

There had previously been limited understanding in how plutonium was released from the particles into the environment for uptake by wildlife around Maralinga.

The new study, published in Nature’s Scientific Reports, led by Monash University researchers, warns the hot particles are more complex and varied than previously thought.

Currently, there are no international best practice standards for the environmental impact or risk assessment of plutonium and uranium-rich hot particles released during nuclear testing.

This study provides the first mechanism for future modelling to predict the environmental life cycle of plutonium from hot particles, including how they are slowly broken down in the environment over a long period, and potentially exposed to animals and humans through inhalation, soil or ground water.

“The resulting radioactive contamination and cover-up continues to haunt us,” lead study author from Monash University’s School of Earth, Atmosphere and Environment Dr Megan Cook said.

“The results of our study profoundly changes our understanding of the nature of hot particles at Maralinga – despite the fact that those were some of the best studied particles anywhere in the world.”

Sue Haseldine, who grew up in the Koonibba district in the 1950s and 1960s, has long campaigned against nuclear testing and weapons.

She has been part of the International Campaign to Abolish Nuclear Weapons (ICAN), an organisation awarded the Nobel Peace Prize in 2017, and has spoken about her experience growing up in the shadow of nuclear testing at Maralinga.

Ms Haseldine said the people in the area had long-suspected there were health issues deriving from those tests.

“Experts would tell you that radiation will not last for 60 years, nor 60,000, but for a long, long time, and it is still causing troubles today,” she said.

“The old ladies told me these cancers and illnesses were not around before the bomb and over the years I have seen the rates go up.

“There are a lot more younger people with heart problems – it is known that radiation problems can cause heart diseases – and it is coming down through the generations.”

Ms Haseldine said the testing and fallout from Maralinga was not spoken about enough and that was why her campaigning with ICAN was so important.

“It is important to let people know what the government’s legacy is to us through their testing and we have to keep the past alive to protect the future, so they don’t do it to future generations,” she said.

“I grew up in the Koonibba district, but the radiation didn’t just stay in the Maralinga area.”

Study co-author professor Joël Brugger said the study invited a revisit of the implications of earlier results for the fate of plutonium at Maralinga.

“Understanding the fate of hot particles in the arid environment setting of the Australian outback is critical for securing Australia in case of nuclear incidents in the region, and returning all the native land affected by the British tests to the traditional Anangu owners of the Maralinga Tjarutja lands.”

The research team used synchrotron radiation at the Diamond Light Source near Oxford in the United Kingdom to decipher the physical and chemical make-up of the particles.

At Monash, they dissected some of the hot particles using a nano-sized ion beam, and further characterised the complex make-up of these particles down to the nano-size.

“It’s a major breakthrough,” study co-author associate professor Vanessa Wong said.

“Our observations of the hot particles from Maralinga provide a clear explanation for the complex and variable behaviour of different hot particles with respect to the chemical and physical weathering that has hindered predictive modelling to this day.

“This study provides a mechanistic foundation for predicting the future evolution of hot particles from high-temperature nuclear events and the likely exposure pathways.”

The researchers demonstrated the complexity of the hot particles arose from the cooling of polymetallic melts from thousands of degrees Celsius in the explosion cloud during their formation.

“We found that the particles contained low-valence plutonium-uranium-carbon compounds that are typically highly reactive – which is unexpected for particles that survived for over 30 years in the environment,” corresponding author Dr Barbara Etschmann said.

U.S. Energy Information reports uranium at lowest price since 2007

Uranium Week: Struggling With Low Prices

FN Arena    Weekly Reports By Mark Woodruff May 25 2021, As the uranium spot price rose 2% for the week and 9% for the month, an EIA report revealed the lowest price paid since 2007 by owners and operators of US commercial nuclear plants

The US Energy Information Administration (EIA) released both its 2020 US Uranium Marketing Annual Report and its 2020 Domestic Uranium Production Report last week. 

Despite covid roiling energy markets during 2020, the reports pointed to nuclear energy being a fundamental source of base load electricity generation (20%) with capacity factors steady at 94%, explains Canaccord Genuity. The broker believes coverage of future demand will continue to provide an impetus for a more active term market over 2021.

The EIA is responsible for collecting, analysing and disseminating energy information to inform policy making and efficient markets. It also adds to the public understanding of energy and its interaction with the economy and the environment.

The released reports in 2020 quantify developments in the US uranium industry, including decreased inventories, explains industry consultant TradeTech. They also showed an elevated aggregated contractual coverage rate among owners and operators of US civilian nuclear power reactors. Additionally, lower weighted average uranium prices and historically low uranium production were reported.

The Uranium Marketing Annual Report showed owners and operators of US commercial nuclear plants in 2020 purchased nearly 49mlbs uranium from US and foreign suppliers. These were transacted at a weighted-average price of US$33.27/lb, which represents a 1% increase in volume and a -7% decline in price compared to 2019 data. The weighted average price is the lowest price paid by owners and operators of US civilian power reactors since 2007.

Of the US deliveries, 76% were through longer-term contracts, averaging US$34.74/lb. As Canaccord notes, it’s always darkest before the dawn, with pricing failing to represent the marginal cost of production let alone the incentivisation price for restarts or new developments.

During 2020, 11.7mlbs or 24% of sales were on a spot basis, up from 10.5mlbs in 2019 and the highest since 2014. This illustrates that long-term contracts signed post-Fukushima (2011-2015) are starting to expire, explains Canaccord.

The report showed Australian and Canadian-origin uranium combined accounted for 42% of reported volumes by country of origin. Uranium purchased by owners and operators of US civilian power reactors from Russia again was the lowest weighted average price paid at US$25.73/lb, while purchases from Australia occupied the highest cost position at US$39.86/lb.;;;;;;;;;;;;;; https://www.fnarena.com/index.php/2021/05/25/uranium-week-struggling-with-low-prices/

Radioactive particles still endanger wildlife in the landscape around Maralinga.

Daily Mail 25th May 2021, Soil in Australian outback could STILL be leaking plutonium 65 years after
British nuclear tests. Almost 60 years after nuclear tests in the Australian outback, radioactive particles still pose a risk to wildlife and residents, according to new report. In the mid-1950s, Great Britain tested nuclear weapons at Maralinga, a remote area about 500 miles northwest of Adelaide. Radioactive waste dotted the landscape for decades and the
Australian government has spent millions on cleanup.

Australian company Greenland Minerals fails community test over controversial rare earths and uranium mine plan

Greenland Minerals fails community test over controversial rare earths and uranium mine plan,  https://www.acf.org.au/greenland-minerals-fails-community-test 27 May 21, It is a long way from Greenland to Western Australia, but concerns from the Narsaq community in Greenland about a controversial mining project will be raised at today’s annual meeting of Perth-based company Greenland Minerals, listed on the ASX as GGG, which is behind the Kvanefjeld rare earths and uranium mine.

Opposition to the planned mine dominated Greenland’s recent national elections. On 6 April Greenlanders elected the Inuit Ataqatigiit (Community for the People) party, which campaigned on an explicit platform opposing Kvanefjeld.

The new coalition government has committed to stop the mine going ahead.

“When a mine proposal triggers an election and the results show a clear rejection of the project, it is time for the company to accept the community’s will and end its mining plans,” said Mineral Policy Institute board member Dr Lian Sinclair, who will attend the GGG meeting.

Australian groups are calling on GGG to recognise that it has failed to secure social license for the Kvanefjeld project.

“We need a different approach to mining, one based on free, prior and informed consent,” said Australian Conservation Foundation nuclear free campaigner Dave Sweeney.

“Mining materials that are used in renewable energy does necessarily make a company ethical or responsible.

“There are dangerous radioactive elements within these deposits, including uranium, that pose long term environmental and health risks.

“These risks should not be imposed on an unwilling community.

“The Narsaq and wider Greenland community and the new Government have rejected this project. GGG should recognise and respect this clear and democratic decision”.

For USA, health care is too costly, while weapons makers wildly profitable -as $634 Billion to go to nuclear arms

The US Will Spend on Nuclear Weapons in the Next Decade,  https://jacobinmag.com/2021/05/military-spending-nuclear-weapons-department-of-defense

BY JULIA ROCK, 26 May 21, According to a new Congressional Budget Office report, we’re set to spend well over a half a trillion dollars over the next decade on nuclear weapons. Yet we’re somehow told that Medicare for All is too expensive.

As Capitol Hill lawmakers continue to insist that initiatives like Medicare for All are too expensive, a new congressional report shows that the United States government is on a path to spend more than a half-trillion dollars on nuclear weapons in just the next decade. The report emerges at the same time a separate analysis shows that a handful of top executives at defense contractors are being wildly enriched by a Pentagon spending spree.

The first report from the Congressional Budget Office (CBO) finds that the federal government is on track to spend $634 billion over the next decade to maintain its nuclear forces. Almost two-thirds of those costs are for the Department of Defense, mostly to maintain ballistic missile submarines and intercontinental ballistic missiles. About one-third is for the Department of Energy.

For comparison that is:

The new CBO estimate represents a 28 percent increase over the last ten-year estimate that the CBO made on US nuclear forces two years ago.

The figures were released just a few weeks after a new analysis from the Center for International Policy, a foreign policy think tank in Washington, found that “In 2020 alone, the CEOs of the [Pentagon’s] top five contractors received a total of $105.4 million in compensation.”

When accounting for all top corporate officials, these firms paid out more than a quarter billion dollars of total executive compensation in 2020 — and paid out more than $1 billion over the last four years.

About half of the Pentagon’s budget goes directly to corporations such as Lockheed Martin and General Dynamics, according to the report.

So far, the deficit scolds who wanted to narrow eligibility for stimulus checksstudent debt cancellation, or rent relief haven’t complained about the spending.

American experts warn Trudeau that small nuclear reactors are likely to prove a nightmare for Canada

The critics contend that SMRs are costly, unproven and creators of toxic waste of their own. From a practical point of view, it is hard to make the case that SMRs will be crucial in the battle against climate change, since they won’t come off the drawing board for years, if ever. Former Green Party leader Elizabeth May says that opting for experimental SMRs is just another way of delaying real action on global warming.

US Experts to Trudeau: Your Nuclear Dream May Turn Nightmare   https://thetyee.ca/Analysis/2021/05/26/US-Experts-Trudeau-Your-Nuclear-Dream-May-Turn-Nightmare/?utm_source=daily&utm_medium=email&utm_campaign=260521

Rethink backing the Moltex reactor, urge nine non-proliferation heavyweights.

Michael Harris TheTyee.ca, 6 May 21, A blue-ribbon group of American nuclear non-proliferation experts warns that Canada’s investment in new nuclear technology could lead to the spread of nuclear weapons and new threats to the environment.

“We write as U.S. non-proliferation experts and former government officials and advisors with related responsibilities to express our concern about your government’s financial support of Moltex — a startup company that proposes to reprocess CANDU spent fuel to recover its contained plutonium for use in molten-salt-cooled reactors.”

The warning came in the form of an open letter to Prime Minister Justin Trudeau that was delivered on Tuesday and signed by the nine experts.

The group is spearheaded by Frank von Hippel, professor and senior research physicist at Princeton University; it includes Matthew Bunn, the Schlesinger professor of the practise of energy, national security, and foreign policy at the Harvard Kennedy School; and Thomas Countryman, former U.S. assistant secretary of state for non-proliferation.

“We understand your government’s motivation to support nuclear power and to reduce fossil fuel use but saving the world from climate disaster need not be in conflict with saving it from nuclear weapons. Also, like other reprocessing efforts, Moltex, even in the R&D stage, would create a costly legacy of contaminated facilities and radioactive waste streams, and require substantial additional government funding for cleanup and stabilization prior to disposal,” they wrote.

Rory O’Sullivan, CEO of Moltex North America painted a very different picture of his company’s experimental technology in an interview with World Nuclear News: “We are working to develop a technology that uses the fuel from the first generation of nuclear power to the next. This reduces the challenges associated with spent nuclear fuel, while expanding nuclear power to help Canada achieve its climate change objectives.”

The Trudeau government has invested $50.5 million in Moltex, and backs the company’s plan to build a 300 MW molten salt reactor in New Brunswick on the Bay of Fundy. Theoretically, it would then reprocess spent fuel from the Point Lepreau nuclear plant, which is set to be decommissioned in 2040.

The Moltex reactor belongs to a class of nuclear power plants termed small modular reactors or SMRs that generate small amounts of electricity in comparison with typical CANDU reactors.

Natural Resources Minister Seamus O’Regan has said that Canada can’t get to net-zero carbon emissions by 2050 without nuclear as part of the equation, along with renewables.

Despite marketing its roll of the dice on Moltex as part of its war on climate change, Ottawa isn’t getting much love from environmentalists, or many other people. Three federal political parties, the NDP, the Bloc and the Greens; the Green Budget Coalition; and the Canadian Environmental Law Association all oppose the federal investment in small modular reactors. University of British Columbia professor of public policy and global affairs M.V. Ramana has levelled criticisms in these pages as well.

The critics contend that SMRs are costly, unproven and creators of toxic waste of their own. From a practical point of view, it is hard to make the case that SMRs will be crucial in the battle against climate change, since they won’t come off the drawing board for years, if ever. Former Green Party leader Elizabeth May says that opting for experimental SMRs is just another way of delaying real action on global warming.

One who has closely followed and opposes the two experimental SMR reactors planned for New Brunswick, the ARC-100 and the Moltex SSR, is Dr. Susan O’Donnell, an adjunct professor of sociology at the University of New Brunswick. O’Donnell is also the primary investigator of Raven, a research team based at the university dedicated to highlighting rural environmental issues in the province.

O’Donnell points out that Moltex has never built a nuclear reactor before. In fact, only two molten salt reactors have ever been built — 50 years ago. Neither of them produced electricity. One of them lasted four years before shutting down, the other, just 100 hours.

On the environmental side, O’Donnell says that SMR pollution or a serious failure could lead to “disasters and no-go zones.”

On the non-proliferation front, she denounces the plan to broadly “export” the Moltex technology, assuming it ever gets up and running.

“What we have learned from Canada’s role in making India a nuclear power is that one of the dangers of the Moltex proposal is its plan to export the technology. We’re exporting bomb-making capacity,” she told The Tyee.

O’Donnell has pushed for public consultations to help develop a national radioactive waste policy. Last Aug. 13, she made an offer to the federal minister of natural resources to have the Raven project organize such a public consultation in New Brunswick. It would be online because of the pandemic, in both official languages, and would include Indigenous nations and rural communities. Minister O’Regan responded two months later, on Oct. 30, turning her down.

“Strangely, he cited the pandemic, even though our offer clearly stated the consultation would be virtual,” the professor said.

O’Donnell’s take on the Moltex project is backed up by Allison Macfarlane, former chair of the U.S. Nuclear Regulatory Commission. The specialist in the storage of nuclear waste told the CBC in January that the molten salt technology is totally unproven with respect to viability, costs and storage risks.

“Nobody knows what the numbers are, and anybody who gives you numbers is selling you a bridge to nowhere…. Nobody’s been able to answer my questions yet on what all those wastes are, and how much of them there are, and how heat-producing they are and what their compositions are,” Macfarlane said. She is now the director of the School of Public Policy and Global Affairs at UBC.

But the Trudeau government does have allies at the provincial level for its nuclear ambitions. The governments of New Brunswick, Ontario, Saskatchewan and Alberta have all signed a memorandum of understanding to develop SMRs, which means promoting them.

They are excited about the promises by Moltex that it will be able to produce clean energy at a low cost by recycling something that everyone wants to get rid of — the three million spent fuel bundles in Canada that the government still doesn’t know how to dispose of safely and permanently.

The U.S. experts made clear to the PM in their letter that they are not convinced by the company’s assertions. They want the Trudeau government to convene a high-level review of both the non-proliferation and environmental implications of Moltex’s reprocessing proposal. Key to that proposal is including “independent international experts,” before Ottawa makes any further investments in support of the Moltex proposal.

The earliest projects to reprocess nuclear waste extracted plutonium to make nuclear weapons. The letter signees worry Canada’s new generation of reactors will afford the same opportunity to anyone who buys them.

“Our main concern is that, by backing spent-fuel reprocessing and plutonium extraction, the government of Canada will undermine the global nuclear weapons non-proliferation regime that Canada has done so much to strengthen. Canada is a founding member of the Nuclear Suppliers Group, which was established in 1974 in response to India’s misuse of a Canada-supplied research reactor and U.S.-supplied reprocessing technology to acquire the plutonium needed for its first nuclear weapons.”

The reprocessing of nuclear waste was “indefinitely deferred” in the United States by president Jimmy Carter in 1977 after India tested its first nuclear weapon. At the time, the Americans discovered that several other countries including Brazil, Pakistan, South Korea and Taiwan were all surreptitiously headed down the same nuclear weapons path that India had taken. Of that group, only Pakistan managed to get the bomb.

The U.S. experts who signed the letter to Trudeau also rejected the claim by Moltex that by using spent fuel from older Canadian CANDU reactors, its reactor would reduce the long-term risk from a deep underground radioactive waste repository.

The Trudeau government promised it would base its major policies on science. It’s time for the public consultation, far from the greasy paws of lobbyists, and with the best minds that can be brought to the table.

This is a letter to take to heart.
