This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
No bigotry, sexism, racism, antisemitism, dehumanization of minorities, or glorification of National Socialism.
Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
Light-hearted content, memes, and posts about your European everyday belong in !yurop@lemm.ee. (They're cool, you should subscribe there too!)
Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)

(This list may get expanded when necessary.)

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

If you want to protest a removal or ban, feel free to write privately to the mods: @federalreverse@feddit.org, @poVoq@slrpnk.net, or @anzo@programming.dev.

The UK's nuclear waste problem: Safety concerns as 'highly radioactive' material could be buried in the English countryside (theweek.com)

"Not in my backyard" is a term normally used in conversations about proposed new housing or rail lines, but a version of it could soon be heard about one of the most dangerous materials on the planet.

[...]

Sellafield, in Cumbria, is the "temporary home to the vast majority of the UK's radioactive nuclear waste", said the BBC, "as well as the world's largest stockpile of plutonium". It's stuck there because no long-term, high-level waste facilities have been created to deal with it.

The "highly radioactive material" releases energy that can infiltrate and damage the cells in our bodies, Claire Corkhill, professor of radioactive waste management at the University of Bristol, said, and "it remains hazardous for 100,000 years".

The permanent plan to handle the waste currently at Sellafield is to first build a designated 650ft-deep pit to store it. Although the contentious matter of its location has yet to be agreed, the facility will hold some of the 5 million tonnes of waste generated by nuclear power stations over the past seven decades. Then, in the second half of the century, a much deeper geological disposal site will be dug, which will hold the UK's "most dangerous waste", such as plutonium.

Nuclear what?

I work in hazardous materials handling and safety (general as well as hazardous materials).

The majority of the waste isn't high-level, and can be relatively safely disposed of. The vast majority of the high-level waste at Sellafield comes from nuclear weapons manufacturing. But thanks to amazing cold-wat era record~~burning~~keeping, nobody really what is what. A sealed vessel could hold harmless coveralls, or toxic sludge, and nobody knows anything other than that it's built to literally without bombing, so it's insanely slow going.

The actual civilian spent reactor fuel is a tiny fraction of what is at Sellafield, and it's some of the easiest material to dispose of, since they're packaged solids. The real headaches are the contaminated machinery and the nuclear weapon sludge.

So yes, nuclear power is safe and clean. Nuclear weapons being made at the cold in secret labs? Not so much. But Sellafield is only a problem because the Brits kept notes. The US dug holes in the desert and poured their nuclear sludge into them, then promptly forgot all about the. The Soviet Union did god knows what with their waste. The French poured it into the ocean.

In hazardous waste handling, the best waste is contained waste, and that doesn't apply to any other fossil fuel. CO2 kills tens of million every year through global warming and many more die from dust, where nuclear energy deaths from all sources barely register.
