Australian news, and some related international items

Wiscasset – just one of thousands of American communities stuck with stranded nuclear wastes.

The situation in Wiscasset underscores a thorny issue facing more than 100 communities across the U.S.: What to do with hundreds of thousands of tons of nuclear waste that has no place to go.

Securing these remnants of nuclear energy generation is an ongoing task that requires armed guards around the clock and costs Maine Yankee’s owners some $10 million per year, which is being paid for with money from the government.

All told, the country’s many abandoned nuclear facilities — including Maine Yankee — have cost the federal government billions of dollars, a sum that increases by about $2 million each day

Keeping the spent fuel on the site was meant to be a temporary solution until the dry storage casks, or canisters, could be transported to a permanent home deep underground where they could stay undisturbed for hundreds of thousands of years.

Armed Guards Protect Tons Of Nuclear Waste That Maine Can’t Get Rid Of  Maine Public | By By Abigail Curtis, BDN July 19, 2021  In the summertime, the picturesque village of Wiscasset is infamous for its long lines of people hungry to try a lobster roll at Red’s Eats and cars that crawl through town on the often-clogged U.S. Route 1.

But just a few miles south of downtown is a different kind of roadblock: thousands of tons of nuclear waste stored on a coastal peninsula at the now-decommissioned Maine Yankee atomic energy plant that have nowhere to go.

The change in presidential administrations means another chance for the federal government to make good on its promise to remove the waste, so the site can be closed for good. The Biden administration’s Department of Energy seems to be picking up where the Obama administration left off, creating a process for communities to volunteer to host the waste.

“What worries me is that there really isn’t any national leadership right now on this stuff. There isn’t an agency that has a mission and has developed a strategy, that has goals and is willing to act on it,” Don Hudson, the chairman of the Maine Yankee Community Advisory Panel, said. “We’re currently in this limbo.”

That’s a problem because the waste — 1,400 spent nuclear fuel rods housed in 60 cement and steel canisters, plus four canisters of irradiated steel removed from the nuclear reactor when it was taken down — is safe for now, but can’t stay in Wiscasset forever.

The situation in Wiscasset underscores a thorny issue facing more than 100 communities across the U.S.: What to do with hundreds of thousands of tons of nuclear waste that has no place to go.

Securing these remnants of nuclear energy generation is an ongoing task that requires armed guards around the clock and costs Maine Yankee’s owners some $10 million per year, which is being paid for with money from the government.

After the government failed to remove the spent fuel, Maine Yankee and the other two decommissioned nuclear power plants in New England — Connecticut Yankee in East Hampton, Connecticut, and Yankee Atomic in Rowe, Massachusetts — took it to court. So far, they have been awarded a total of $575.5 million in damages during four rounds of litigation, money that has been paid out of the U.S. Judgment fund. A fifth round is happening now, and the lawsuits are likely to continue until the fuel is removed.

Small nuclear reactor project cut back to half size, due to financial worries

Eastern Idaho nuclear project goes from 12 to six reactors.  IDAHO FALLS, Idaho (AP) 19 July 21— A Utah energy cooperative said it will reduce the number of small modular nuclear reactors it will build in Idaho from 12 to six for a first-of-a-kind project  [ totally ineffective against global heating] that is part of a federal effort to reduce greenhouse gasses that cause climate change……

The reactors are being built by Portland, Oregon-based NuScale Power. The U.S. Nuclear Regulatory Commission last year approved NuScale’s application for the small modular reactors, the first time U.S. officials approved a design for a small commercial nuclear reactor.

………….. Idaho Falls has committed to buying 5 megawatts of power from the reactors through the Carbon Free Power Project. The city had been committed to 10 megawatts but cut that in half in October amid concerns about financial risks.

………..  Idaho Falls City Council member John Radford said at a July 8 meeting. “This project is something that can help keep this country on this trajectory to a carbon-free future and maybe a better existence for all of us.” – [a complete untruth!!     this Councillor is either ignorant, or lying]  https://madison.com/news/national/govt-and-politics/eastern-idaho-nuclear-project-goes-from-12-to-six-reactors/article_cb353af6-5659-5baa-8365-dc575aeeba8d.html

City Council in Calgary, Canada, not happy about ”rushed” agreement to own stranded nuclear wastes in Maine.

The 11-acre temporary storage site is patrolled around the clock by armed security guards.

The situation concerns Coun. Evan Woolley, who said that Enmax never mentioned the spent nuclear fuel site when the utility briefed city council on its bid for Versant.

Calgarians have a stake in Maine nuclear fuel storage facility  AT TOP https://mail.google.com/mail/u/0/?tab=rm&ogbl#inbox/KtbxLthlxCLcsbdhrlMgpmhjJQTWxmvSdV?compose=new

Facility part of the deal when Enmax bought U.S. utility for $1.8 billion, including debt

Scott Dippel · CBC News ·  Jul 19, 2021 Enmax’s acquisition of a utility in Maine last year came with a nuclear surprise that city council members say they weren’t told about.

When the city-owned Enmax closed on its deal to buy Versant Power (formerly Emera Maine) in March of 2020, it also acquired Versant’s interest in a former nuclear power plant.

The Maine Yankee plant operated from 1972 to 1996 and was decommissioned in 2005.

Versant owned 12 per cent of the electricity generated by the power plant. Its ratepayers also paid up front for 12 per cent of the decommissioning costs.

The plant was torn down and tonnes of spent nuclear fuel rods from the facility were temporarily encased in 64 concrete silos at a protected site in Wiscassett, Maine.

Part of the deal

The president of Versant Power, John Flynn, tells CBC News that Enmax couldn’t avoid taking on the Maine Yankee obligation when it purchased Versant.

“As part of the acquisition, Enmax really didn’t have the opportunity to pick and choose the assets or relationships or obligations it wanted,” said Flynn. “It was making a bid for the entire company.”

He said there isn’t a market for a temporary nuclear waste storage facility, so any buyer of Versant would have had to take on that obligation.

There are approximately $10 million US in annual costs related to the safe operation of the spent nuclear fuel storage site, including monitoring, maintenance and security.

About 38 people work at the site.

But Flynn said this doesn’t actually cost Versant or Enmax any money.


It’s covered by a trust fund which includes legal settlements from the US Department of Energy (DOE), which has a legal responsibility to ultimately remove the tonnes of spent fuel and find a permanent storage site.

Temporary site may be used for years

Flynn said there’s currently no estimate from the DOE on when it may move the materials to a final storage site.

He said the trust fund has enough money in it that the operation of the temporary facility will be covered for years to come.

In some years, Flynn said annual payments from the fund have been made to Versant customers who prepaid the decommissioning costs during the years the nuclear power plant was in operation.

The 11-acre temporary storage site is patrolled around the clock by armed security guards.

“The entire site is surrounded by a security perimeter that has 24/7 security that is of the level you would expect to see on an army base, so it is a hyper-secure site.”

While Enmax says it doesn’t own the spent nuclear fuel, it does list in its annual financial report the historical 12 per cent interest in Maine Yankee.

Council kept in dark

The situation concerns Coun. Evan Woolley, who said that Enmax never mentioned the spent nuclear fuel site when the utility briefed city council on its bid for Versant.

He is one of several council members contacted by CBC News who said they were unaware of that part of the $1.3 billion acquisition, which also included $500 million in debt.

Owning 12 per cent of a company that owns a bunch of nuclear waste has not only reputational risk but also real risk in terms of the world that we live in,” said Woolley.

The Ward 8 councillor, who is also the chair of council’s audit committee, said he would have liked to have known this information before council approved Enmax’s purchase.

“For us to not have been made aware of that is unacceptable,” said Woolley.

“Enmax and now Versant Power, which was Emera Maine, is owned by Calgarians. So council and the shareholder are accountable for that decision.”

Outside eyes needed

He describes Enmax’s pitch to city council to approve its takeover of the company in Maine as “rushed.”

His preference is that in future, a third party could assess such business opportunities for council and make a recommendation. 

That perspective could come from the city’s chief financial officer, the city solicitor or an external consultant.

A report is expected before the audit committee in September, which he said could result in changes that could help ensure Enmax and all of the city’s wholly-owned subsidiaries are on the same page as city council in the future.

He describes Enmax as “the massive gorilla in the room in terms of its size and scale.”  “The risk appetite of Enmax versus the risk appetite of a shareholder are different. And that’s where we need to provide better alignment,” said Woolley.

If council approves of any changes for its subsidiaries, he said it would mean that another transaction like the Versant purchase could not occur in the way that it did.

Canada’s small nuclear reactor project is looking like just a pipe-dream.

Globe Climate: Canada wants nuclear to power the future. But how? SIERRA BEIN Matthew McClearn is an investigative reporter and data journalist with The Globe. For this week’sdeeper dive, he talks about Canada’s nuclear ambitions. Globe and Mail, 19 July 21

Senior government officials, notably federal Natural Resources Minister Seamus O’Regan, say small modular reactors (SMRs) will help Canada achieve net-zero carbon emissions by mid-century. There’s just one problem: it’s not clear yet whether any will be built.

To be sure, many promises made by SMR vendors seem compelling. By taking advantage of factory-style mass production, they’re supposed to be far cheaper than previous generations of reactors, which tended to be massive and prone to cost overruns. They’d also be easier to deploy…….. 

A mad scramble to deliver on these promises is now underway. Ontario Power Generation—by far Canada’s most experienced nuclear station operator—plans to select a vendor to build a SMR at its Darlington Station by 2028. Further out, Saskatchewan is considering whether to order its own SMRs to replace coal-fired plants.

Accomplishing all that would silence numerous critics and naysayers. But as I explain in my most recent story, history is littered with reactors that failed to live up to their promises.   . Many SMR vendors are very early-stage companies which face years of grueling, expensive R&D work to advance their designs to the point they could actually be built. And they’re competing against renewable technologies including wind and solar, which utilities can purchase and deploy today. It may be premature to count on SMRs to help meet Canada’s emissions targets.   https://www.theglobeandmail.com/canada/article-globe-climate-canada-wants-nuclear-to-power-the-future-but-how/https://www.theglobeandmail.com/canada/article-globe-climate-canada-wants-nuclear-to-power-the-future-but-how/

After the lab-leak theory, US-Chinese relations head downhill

The United States and China could work together in sharing biosecurity-related samples, genetic materials and data, developing protocols and countermeasures against biosafety accidents, promoting transparency in dual-use research of concern, countering disinformation, and strengthening compliance with global health laws, including the Biological Weapons Convention and the International Health Regulations.

But the US push to investigate the lab leak and the political context in both countries likely puts the goal of finding the origins of COVID-19 and many other ambitions at risk………

After the lab-leak theory, US-Chinese relations head downhill, Bulletin of the Atomic Scientists, By Yanzhong Huang | July 16, 2021  In October, 2018, more than a year before the COVID-19 pandemic, dozens of international trainees visited the Wuhan Institute of Virology for an expansive workshop meant to “promote the cooperation between China and other countries in the field of biosafety.” The attendees, many from developing countries, took classes on virus handling and bioethics, they listened to speeches by Chinese and UN arms control officials, and learned from eminent scientists. For the organizers, the 10-day event was a chance to showcase China’s expertise in biosafety management. And for this, they could hardly have chosen a more perfect location, a prestigious virology institute that had just months earlier opened the country’s first state-of-the-art, specialized facility for safely studying the world’s most dangerous pathogens, a biosafety-level (BSL) 4 lab.

The marketing plan hasn’t paid out.

Two years on, the lofty vision the workshop at the advanced Chinese biolab embodied—one of international collaboration on disease control and scientific research—has disintegrated as the United States and China tangle in an increasingly nasty fight over the origins of the still-raging coronavirus pandemic. In the United States, President Joe Biden, prominent scientists, and once-skeptical mainstream media outlets have collectively revived a hypothesis that was initially largely framed as a conspiracy theory, that the COVID-19 virus could have escaped from the Wuhan lab. Meanwhile, in China, many are convinced COVID-19 started somewhere else, outside of the country.

The Wuhan Institute of Virology now sits at the forefront of the US-China row on the origins of a once-in-a-century pandemic.

ANSTO aims to speed up return to Australia of highly hazardous nuclear wastes

 

nuclear waste container unloading at Port Kembla

It is ‘highly hazardous’ nuclear wastes... said previously to be due “before 2023”
There is a federal PWC Inquiry on now into ANSTO ILW works – input due by Fri 30 July.

ANSTO seeks to repatriate more nuclear waste from overseas https://www.illawarramercury.com.au/story/7345341/plan-to-bring-back-more-of-australias-nuclear-waste/

 Natalie Croxon,

Australia’s nuclear agency plans to bring back a second cask of its radioactive waste back from overseas, following a major operation that saw a container unloaded at Port Kembla in 2015.

Australia does not have the capacity to reprocess the spent fuel rods from its nuclear operations, so the Australian Nuclear Science and Technology Organisation sends these overseas where any remaining uranium is stripped and recycled.

The remainder of the waste goes through a process in which it is solidified in molten glass and placed in 500 kilogram canisters.

These canisters are then put into a transport cask with 20 centimetre-thick walls made from forged steel for shipping to Australia.

Subject to approvals, ANSTO plans to bring back its second of these casks from overseas next year, this time from the United Kingdom.

It will be taken to ANSTO’s interim waste storage facility at Lucas Heights in southern Sydney.

While ANSTO will not yet disclose the route and timing of the transport for security reasons, the 2015 operation saw the waste shipped into Port Kembla before it was taken by road to Lucas Heights.

ANSTO says between 75 and 80 per cent of the nuclear waste it produces is associated with the production of nuclear medicine.

“For decades, Australians have benefited from nuclear medicine, and environmental, industrial and minerals research undertaken at Lucas Heights,” ANSTO’s chief nuclear officer Hef Griffiths said.

“Those benefits include production of millions of doses of nuclear medicine, increased profitability of our mining industry, irradiation of silicon used in everything from fast trains to hybrid cars, and a base of knowledge that secures Australia’s position in international nuclear non-proliferation talks.

“Along with these benefits comes a responsibility for Australia to safely deal with the by-products including radioactive waste.

“Australia does not shy away from that responsibility, and ANSTO has comprehensive plans to safely manage it.”

On a scale of low to high, the waste to be repatriated from the UK is classed as intermediate-level waste: this means it requires additional shielding during handling, transport and storage, but does not have levels of radiation as high as high-level waste.

ANSTO says the cask to be used for this waste is so heavily shielded that there will be no detectable traces of radiation above background levels for someone standing right beside it.

It will be stored at ANSTO’s interim waste facility until a national nuclear waste management facility is established around the end of the decade.

With all its wisdom, the human race is killing itself

HELEN CALDICOTT: With all its wisdom, the human race is killing itself,  Independent Australia, By Helen Caldicott | 17 July 2021 From a historical perspective, Homo sapiens are an evolutionary aberrant.

Unlike other forms of life, armed with an opposing thumb and a highly developed and advanced neocortex, we have, over time, developed the capacity to destroy most organisms on planet Earth.

This has been accomplished either with the energy of heat, light and power that exist inside the sun or, conversely, by slowly cooking the planet as we release fossil gases — carbon dioxide and methane………..

Little did people know when they developed steam engines, motor cars and factories that were powered by these fossil fuels that within several centuries, such wonderful inventions which made life incredibly easy would, in the long run, threaten the biosphere with eventual extinction.

And ever since humans evolved, the male species has seen fit to harness the overwhelming power of testosterone to kill invading species, but more to the point, slaughter his fellow constituents for territorial gains, power plays and control dynamics. Yes, it is true that other male species will fight to the kill over mating imperatives, food or territorial control, but they have no access to reason, scientific knowledge and moral imperatives.

Congruent with this history, it is obvious that as we became more obsessed with gaining scientific knowledge, such wisdom would be put to better methods of killing.

So where does the human race stand now? Nine countries now own nuclear weapons, with the USA and Russia greatly predominating, owning 94 per cent of all the approximately 14,000 in the world……….

The U.S. now spends over one trillion dollars a year on potential murder, all dressed up in the name of “national defence” which is pure rubbish. Because let’s face it, America has no enemies, Russia has joined the capitalist sphere, China is, at the moment, a little belligerent but the U.S. more so with 800 military bases in 80 foreign countries.

For the human race to survive, it is imperative that we encourage and foster friendship with all nations on Earth, that we reign in the killing testosterone instinct, that women with their nurturing hormones rapidly take control of national governments and pursuant to the teachings of the great moral profits – Jesus, Buddha, Muhammad, and all others – that we rapidly learn to live in peace with each other. Or let’s face it, we are doomed and will take the wonders of billions of years of creation with us. https://independentaustralia.net/article-display/helen-caldicott-with-all-its-wisdom-the-human-race-is-killing-itself,15300

Nuclear colonialism – Australian artist’s work censored in UK

An Australian artist has accused a group of Conservative councillors of
using “bullying strategies” to silence and censor her work after an
installation she created to highlight Britain’s “identity as a colonial
nuclear state” was removed from a park in Essex. The councillors
threatened to “take action against the work” if it was not removed,
according to Metal, the arts organisation that commissioned and then
removed the installation from Gunners Park in Southend.

Australian cities not prepared for the coming heatwaves- poor urban planning

The urban heat dome

The heat is coming and we are not prepared for it.

It is not just that large houses on small blocks leave no room for trees,….. The little space left between them provides no room for recreation and serve to increase heat, with side-passages often home to air-conditioning systems that spew heated air across dividing fences.

When he looks at new developments on the fringes of Australian cities, Pfautsch says residents have been abandoned to wholly predictable heat extremes caused by global warming but exacerbated by poor planning regulation.

We’re ending up with dark-roofed, back-to-back, nose-to-front, housing suburbs on the outskirts of Melbourne. And if you add dark, asphalt and concrete surfaces you’re going to get really hot suburbs,”

Why a killer US heatwave points to a stifling future for our cities. Brisbane Times, By Nick O’Malley and Miki Perkins, July 17, 2021 It was the hellish evening temperatures that finally caused the authorities to start busing the homeless into heat shelters where they had access to fans, air-conditioning and water.

Three hours from sundown last Saturday the temperature in Las Vegas peaked at 47.2 degrees, equalling a record set in 2017. By dawn, the temperature had bottomed out at a stifling 34 degrees and begun to rise again.

One person was treated for burns after walking on a pavement and the homeless were bussed from an outdoor shelter to indoor cooling centres in response.

West of the city at Furnace Creek in Death Valley a temperature of 54.4 degrees was recorded. Experts are still checking the reading and debating over whether this was the hottest temperature ever recorded on earth.

In the town of Lytton in British Columbia, a Canadian heat record was set at the end of last month when the temperature hit 49.6 degrees and lingered up there over three days. Authorities attributed hundreds of deaths across the region to the heat, even before wildfire arrived and burnt most of the village to the ground, killing two more.

Before the flames approached one local, Lorna Fandrich, told the New York Times that she’d noticed green leaves dropping off the trees, apparently unable to tolerate the heat. On the coast to the west, millions of mussels and oysters cooked and died in superheated shallow waters.

From his home outside Sacramento Ken Pimlott, the recently retired head of Cal Fire, the agency responsible for fighting wildfires across the state of California, watched on with dread. The height of the northern fire season, he noted, has not even arrived yet.

These temperatures, Pimlott told The Sydney Morning Herald and The Age, are no longer outliers, but spikes in a new normal in a world not prepared to manage them.

The temperatures have already extended the North American fire season, causing exhaustion among crews who can’t get enough rest from the fire lines and difficulties in keeping up with maintenance demands on equipment. Aircraft once shared with nations like Australia were under greater demand as fire seasons overlapped, he said.

Pimlott’s dread was shared in Australia.

Dr Sebastian Pfautsch, a specialist on urban heat at Western Sydney University, says though Australian attention has drifted from the terrible summer of 2019 and 2020, he fears for the future of residents of some suburbs in Sydney and Melbourne.

The heat is coming, he says, and we are not prepared for it.

Stephen Livesley is an associate professor in forest sciences at the University of Melbourne, and an expert on the benefits of urban forests. “It’s possible we’re going to end up with large neighbourhoods which people in 20 or 30 years’ time will simply avoid,” he says.

This concern is not misjudged, says Professor Christian Jakob, a Monash University atmospheric scientist.

His analysis of the heatwave that struck North America shows that it originated with an unremarkable rainshower on the other side of the Pacific Ocean, not far from Japan.

The shower caused an atmospheric disturbance that in turn created what scientists call a Rossby wave, which was guided towards North America by the jet stream, amplifying as it travelled before breaking upon the shores of the Pacific Northwest.

There the wave caused a high-pressure system. As Jakob explains, air heats under pressure. On the ground, temperatures soared. What caused the temperatures to reach such extremes, though, and what made the system linger long enough to cause such misery and destruction beneath it, cannot yet be explained by science says Jakob.

Until better computer models are created all we can know is that as the climate heats due to global warming such heatwaves will in some areas increase in intensity and duration.

Areas particularly prone to the phenomenon include northern Europe, North America and south-eastern Australia, he says

On the day that Penrith became for a time the hottest place on earth, with temperatures hitting 48.9 degrees on January 4 last year, Keith Heggart’s air conditioner conked out by midday. The manual said it sometimes did that in extreme heat and recommended hosing it down, but due to bushfires water use was banned. Heggart and his young family closed windows against the smoke and the blinds against the sun and sheltered in the living room where a fan pushed around the hot air.

Watching the news from America these past few weeks, Heggart has fretted about the summers to come. His street in Penrith is older than others and there is some shade, some gaps between the houses, but when he looks at the new developments nearby, he despairs.

“There are no trees, there is no shade,” he says. “You could reach out your window and touch the house next door.

When he looks at new developments on the fringes of Australian cities, Pfautsch says residents have been abandoned to wholly predictable heat extremes caused by global warming but exacerbated by poor planning regulation.

Council areas such as Blacktown, Penrith and Campbelltown in Sydney and suburbs like Wollert, Mernda and Mickleham in Melbourne are compelled to absorb growing populations by state governments, but are failing to impose proper planning regulations. Strapped for cash, they have allowed property developers to shape the built environment, he says.

…….. It is not just that large houses on small blocks leave no room for trees, Pfautsch says. The little space left between them provides no room for recreation and serve to increase heat, with side-passages often home to air-conditioning systems that spew heated air across dividing fences.

But Pfautsch sees other wilful mistakes. Unshaded black roads absorb heat during the day only to radiate it at night, extending the heat of day into the evening. This contributes to the urban heat island effect.

Roofs, exterior walls and even driveways created by developers in currently fashionable dark shades serve to exacerbate the impact, he says.

But, according to Pfautsch, the problems begin even before the new suburbs are laid out, when developers clear new sites of all existing trees, ponds and watercourses to maximise space and save on construction costs.

What greenspace remains is often not connected to homes by shaded foot or bike paths.

“It is inhumane to expect people to live like this in the temperatures we anticipate,” he says. “I can’t say it more strongly than that.”………….

Overall, Melbourne lost 0.3 per cent of its canopy between 2014 and 2018. Almost 2000 hectares of trees were cut from the east and south-east, mostly at residential properties……….

We’re ending up with dark-roofed, back-to-back, nose-to-front, housing suburbs on the outskirts of Melbourne. And if you add dark, asphalt and concrete surfaces you’re going to get really hot suburbs,” he says. “When you have high-temperature events intersecting with urban heat islands, you have really, really high temperatures.”

According to Pfautsch, even a concerted effort to increase tree coverage in the suburbs most prone to the heat-island effect will only have limited impact in the years to come………

All this raises thorny questions of environmental and climate justice, Livesley says, as the suburbs most affected are often the most affordable.

“We are pushing some of the most vulnerable people in our society into these low tree, low services environments, with poor public transport infrastructure.”…………

In Mildura, a town near the border in north-west Victoria, temperatures have increased in line with worldwide heating trends. Between 1998-99 and 2018-19 the number of days each year where the temperature went above 35 degrees increased by about 20 days, and the number of heatwaves rose from six to nine.

For residents living in public housing – who faced huge bureaucratic hurdles to having air conditioners installed – recent summers have been a nightmare,………..

not only should we be tackling climate change, we should be totally re-imagining how we build our suburbs.  https://www.brisbanetimes.com.au/environment/climate-change/why-a-killer-us-heatwave-points-to-a-stifling-future-for-our-cities-20210716-p58ae9.html
