Revealed: #Sellafield #nuclear site has leak that could pose risk to public

Safety concerns at #Europe’s most #hazardous plant have caused diplomatic tensions with US, Norway and Ireland

Anna Isaac and Alex Lawson
Tue 5 Dec 2023

"Sellafield, Europe’s most hazardous nuclear site, has a worsening leak from a huge silo of #RadioactiveWaste that could pose a risk to the public, the Guardian can reveal.

"Concerns over safety at the crumbling building, as well as cracks in a reservoir of toxic sludge known as B30, have caused diplomatic tensions with countries including the US, Norway and Ireland, which fear Sellafield has failed to get a grip of the problems.

"The leak of radioactive liquid from one of the 'highest nuclear hazards in the UK' – a decaying building at the vast Cumbrian site known as the Magnox swarf storage Silo (MSSS) – is likely to continue to 2050. That could have 'potentially significant consequences' if it gathers pace, risking contaminating #groundwater, according to an official document.

"Cracks have also developed in the concrete and asphalt skin covering the huge pond containing decades of nuclear sludge, part of a catalogue of safety problems at the site.

"These concerns have emerged in #NuclearLeaks, a year-long #Guardian investigation into problems spanning cyber #hacking, #radioactivecontamination and toxic #workplace culture at the vast nuclear dump.

"Sellafield, a sprawling 6 sq km (2 sq mile) site on the Cumbrian coast employing 11,000 people, stores and treats nuclear waste from weapons programmes and nuclear power generation, and is the largest such facility in Europe."

We’ve got to come to grips with the fact that #ClimateChange will almost assuredly result in societal collapses - at least regionally. While #nuclear power is mostly safe when managed by competent people with intact infrastructure like external power for cooling, what happens when that infrastructure collapses and those competent personnel are no longer being paid and need to hunt for food and water for their families?

Investing in any technology that can’t safely be turned off and walked away from in a crisis is investing in a catastrophe multiplier.

Yesterday, it was revealed there had been hacks and security breaches at a large nuclear site in the UK.

Today, we learn there's a radioactive leak that's been causing diplomatic tensions with the US, Norway, and Ireland — and obviously could pose a real health threat.

This should be headline news, not just in the Guardian. Sellafield/the government largely rejected yesterday's claims, but they've been quiet about the latest ones.

There’s a few IPCC AR6 technical summaries but none has page 123 and there’s no statement to the effect you wrote, so I assume you copied that from Wikipedia or some renewables fanpages 😉

The correct IPCC report to refer in terms of electricity sources is AR6 WG3 (mitigation). And while it does certainly note massive growth in renewables capacity, it’s also quite clear that as of today, #nuclear is the largest single low-carbon source, which has delivered more (2790 TWh) electricity in 2019 than wind and solar together (2100 TWh) in spite of its slow growth:

Solar PV grew by 170% (to 680 TWh); wind grew by 70% (to 1420 TWh) from 2015 to 2019. Solar PV and wind together accounted for 21% of total low-carbon electricity generation and 8% of total electricity generation in 2019. Nuclear generation grew 9% between 2015 and 2019 and accounted for 10% of total generation in 2019 (2790 TWh); hydro-electric power grew by 10% and accounted for 16% (4290 TWh) of total generation. In total, lowand zero-carbon electricity generation technologies produced 37% of global electricity in 2019. {6.3, 6.4}

And there’s nothing wrong with that: it’s great that renewables have grown and many countries have potential to grow it much further. The problem is that renewables are variable and the only dispatchable low-carbon sources are hydro power (geographically limited) and nuclear. Countries that ideologically refuse nuclear, like Germany or Australia, almost always end up running on coal and gas.

Exceptions are countries lucky enough to have plenty of potential for hydro power, such as Norway, Sweden, Portugal etc, but you can’t have that in Germany or Poland because nobody is going to flood new valleys for hydro plants.

The most realistic scenarios are therefore those, which assume growth of renewables and nuclear as their baseload supply, as demonstrated by France, Sweden or UK, all of which have significantly lower CO2 emissions already today, especially when compared to Germany which continuously says “but in just ten years we’ll come up with a Wunderwaffe“, be it batteries, be it power-to-gas etc.

Okay, so you seem to be explicitly penalising countries for the use of low-carbon #nuclear electricity, which explains why a country that has one of the largest CO2 emissions in EU scored so high in your ranking. And I’m kind of fine with that, it’s your ranking, so you can use whatever criteria you want. I just have one request: don’t call it ranking of “fossil free world” because you’re only ridiculing yourself by praising Germany that mostly runs on coal and gas as “fossil free”.

I just boosted it, but you should really, really read this article by Michael Barnard on nuclear reactors if you have any interest in the subject:

(Is Barnard on Mastodon? Who knows: it's impossible to search Mastodon for anything as far as I can tell.)

I recommend the article highly but want to quibble with / expand on one point:

"As I noted recently, nuclear energy and free markets aren’t compatible. Nuclear programs are state programs with subordinate corporate partnerships."

A thousand times yes. But this is mostly true of *any* large scale grid-connected energy. You don't just build a power plant, then say eh the free market didn't support it and shut it down, and you don't look at market signals and go "Electricity in (location) is expensive. Looks like we could make a profit by undercutting the market there." No. The electric grid can't fail (at least, in a major industrialized country) and governmental permitting is powerful enough so that none of these things are built without the government basically wanting them built and causing them to be built. *All* of the market talk is more or less a sham and only comes into play when some company like Enron turns it into a scam profit center.

#Sellafield #nuclear site a 'toxic mix of #bullying and harassment'

By Jim Reed and Sarah MacKinlayBBC News
9th March 2021, 09:03 EST

"Fear of reprisals'

"A work environment where staff are treated with dignity and respect is an 'essential trait of a healthy nuclear safety culture', according to the World Association of Nuclear Operators, an organisation formed in the aftermath of the #Chernobyl disaster - of which Sellafield is a member.

"An internal staff survey commissioned by the firm in 2018 and seen by the BBC showed 54% of the employees who filled in the poll agreed they 'could speak out about doing the right thing without fear of reprisals', a fall of 11 percentage points since the previous survey in 2016.

"'Sellafield management said staff surveys brought focus' to concerns about bullying and harassment at the site.

"'We did not ignore this, or seek to cover it up,' said a spokesperson. "We confronted the issue, proactively shared information with employees, and developed a company-wide improvement programme. This work is continuing."

"The BBC has also spoken to a number of former and current members of staff who had concerns about #safety at the site."

Innovative #nuclear reactor concepts are temptingly easy to make but the detailed design always kills them. Our #LDR50 is designed the other way around: aim at simplicity and manufacturability instead of high performance. I think this is the correct way. Performance can only be improved through operational experience. That was also the case with our current operational fleet. If you aim too high, you'll never get it built.

Also, if we stick to chemical content, coal ash also should be qualified as low-level radioactive waste… but it isn’t, because coal industry.

Fossil gas and oil extraction sludge is also radiactive… but it isn’t legally, because oil and gas industry.

Water extracted from geothermal wells is also radioactive because the very concept of geothermal energy originates half in radioactive decay (ongoing) and half in the heat from planet formation (leftover). Of course, it’s not legally radioactive because how could #renewables be regulated in the same way as evil nuclear power?

Rare-earth mining which provides elements critical for modern electronics and especially for photovoltaics also contain a lot of radioactive elements, just as anything mined underground, and it’s also not legally radioactive, because renewables and stuff. That is, unless it happens to be co-mined with uranium, then of course it is, because #nuclear 😂

Radon spas, popular in some countries, where people literally bathe in geothermal water with high radon content, also don’t count as radioactive waste, and in some countries (Austria, Germany) they are actually refunded as legitimate balneotherapy. You can actually imagine the German anti-nuclear protesters celebrating closure of their nuclear power plants in cold weather because “radiation kills”, only to then jump into cosy radioactive bath!

There’s many of these, recommended reading:

Renewables could be online quicker and cheaper.

Germany has the Europe’s largest installed capacity in #renewables. Yet, it runs on coal and gas today, plus some imports from #nuclear France:

Germany’s CO2 emissions intensity right now is nearly 10x worse than France, cost of electricity in Germany is 3x higher than in France, and they had to restart coal mines after Russian pipeline was severed. There’s a simple explanation for that: for most of the time renewables don’t produce electricity, but people want 24/7 supply.

And where are we going to get fuel for them, from Russia?

There’s like 30 countries on the global uranium market and it’s much easier to supply nuclear power plants: a single nuclear power plant consumes maybe 100 tons of uranium fuel per year. That’s around how much a single wind turbine weights, including concrete base, the tower and the blades, and you need hundreds of turbines along with hundreds of MWh in batteries to replace a single plant. In total, renewables consume 300x more mined resources (metals, concrete) than nuclear per MWh of electricity produced.

My linocut print of Lise Meitner holding her glasses in one hand, while leaning on the other, in silver ink. In red ink is a nuclear fission chain reaction shown with a single neutron (white ball with motion lines) emanating from her head towards a nucleus (conglomerate of red proton and white neutron balls) then an arrow to it fissioning (becoming split into two adjacent then two separate halves with extra free neutrons). These neutrons in turn all begin the same process with other nuclei and the chain reaction takes up the left side of the print next to Meitner.

Great summary of why #nuclearPower only works as a top-down, big-government, long-term industry - not via the marketplace. That goes for "small modular" dreams, too.

"The Russians intend to switch the third power unit of the #Zaporizhzhia #Nuclear Power Plant to a hot shutdown, despite the lack of compliance with the licensing requirements of the State Nuclear Regulatory Inspectorate of #Ukraine... Thus, the change in the state of reactor plants, both power unit No 3 and Nos 4-5, is extremely dangerous."

Very similar to the human radiation experiments conducted by the US during the #coldwar

"Punjabi women were given chapatis laced with radioactive isotopes in the 1960s, it's been claimed"

Graphic showing the leaking of the high-level radioactive waste at the Hanford Tank Farms, and the depth of the leakage. An underground plume of the liquid waste has been transporting towards the Columbia River.

This is the same technology as “recycling" nuclear waste from reactors.

happy saturday! did you know that high-altitude nuclear explosions created (temporary, as far as i can tell) artificial radiation belts around the earth?

Oh, but it's safe. No danger here. Yeah right.

I've opposed nuclear energy for over 50 years. It is no safer now than then.

The only nuclear energy we need is 93 million miles away. The Sun can still be dangerous, but we can manage it.

Not to worry people, accidents after an accident are rare. It even becomes rarer to have an accident on top of two preceding accidents. Each new accident means it's even rarer to have another accident, with chances almost vanishing at some point... we think.

This is very bad news for radioactive waste management at #Hanford

"Hanford’s pre-treated waste might not meet Vit Plant criteria"

Much of the worst radioactive waste at Hanford is the "liquid" waste in the Tank Farms. The plan was to vitrify them (enclose them in glass). Now, looks like the Vit Plant may not be up to the task. Billions more wasted after the first Vit Plant was scuttled for safety concerns.

All of the tanks in the Tank Farm are leaking. Workers are hospitalized annually for inhaling toxic fumes working at the site. They may remain with no viable plan to process the waste into a form that is manageable.

A storage tank spoiled a batch of liquid radioactive waste at the Hanford Site that was thought to be clean enough for disposal, according to a contractor memo seen by the Exchange Monitor

Ganz grob pi mal Daumen die Energiemenge im Jahr (wild zusammengeklaubt für DE):

1 GW #nuclear: 7900 GWh
1 GW #wind: 1700 GWh
1 GW #solar: 900 GWh

1 GW nuclear ~= 5GW wind ~= 9 GW solar.

Ein jährlicher Zubau von 392 GWp Solar entspräche also immer noch gut über 40 Kernreaktoren.

Und anders als bei AKWs mit Projektzeiten von im Schnitt 15 Jahren ist das Strom der jetzt bereit steht und tatsächlich was bewirkt.
