Is nuclear waste even still a problem? We have been storing nuclear waste for more than 60 years in ‘temporary facilities ’ while we’re looking for permanent solutions. As far as I know, nothing happened in that time. Let’s just drop the ‘temporary’ label, keep doing what we’re doing and stop worrying about hypothetical scenarios where society will collapse and some farmer 1000 years from now will get radiation poisoning.

I'm a good few miles from Sellafield, but well within the "you're screwed" radius in the event of major leak.

On waste it depends what you call "still a problem". Sellafield still has pools storing the spent Magnox fuel resulting from running Britain's nuclear stock flat out through the 1973 miners strike. Those are decaying "nicely". Risk of fuel fires has been mentioned more than once. Sellafield is a reprocessing plant, that hasn't yet touched the 45 year old waste.

Yes I'd say nuclear waste is still a problem. I'm far enough outside London that politicians probably think it's perfectly fine.

Can you elaborate on what the problem is? I see a photo of a pond with the sun shining, grass growing and seagulls bathing. Authorities say it is safe.

I have friends who live next to an explosives manufacturing plant. They are at a much higher risk then it sounds like you are. I don't see nuclear fuel as being different from any other hazardous industrial material we deal with.

Those are tiny ponds, by the way. I reckon they could have a 2nd set as a backup somewhere near by if it came to it. You should see the size of a mine tailings pond, when they fail it causes real problems.

The problem is nuclear advocates can take the poster child for poor management and say it's perfectly safe:

> Between 1950 and 2000, there were 21 serious incidents or accidents involving off-site radiological releases that warranted a rating on the International Nuclear Event Scale, one at level 5, five at level 4 and fifteen at level 3. Additionally during the 1950s and 1960s there were protracted periods of known, deliberate discharges to the atmosphere of plutonium and irradiated uranium oxide particulates.[81] These frequent incidents, together with the large 2005 THORP plant leak which was not detected for nine months, have led some to doubt the effectiveness of the managerial processes and safety culture on the site over the years. - https://en.wikipedia.org/wiki/Sellafield#Incidents

There's been more than enough problems with nuclear plants that I wouldn't live anywhere near one: https://en.wikipedia.org/wiki/List_of_civilian_nuclear_accid...

Re:The Necessity of Nuclear by roenxi on Monday October 14, 2019 @04:24AM (#21246156)
That is what perfectly safe looks like. The poster child for poor management is acceptably safe. The wiki page includes incidents that are paranoid from the perspective of strategy, eg:

* "resulted in temporary warnings against swimming in the sea along a 10-mile (16 km) stretch of coast between St. Bees and Eskmeals"

* A paperwork issue that was within tolerance of the relevant international standard

* "No radiation was released to the environment, and no one was injured by the incident, but because of the large escape of radioactivity to the secondary containment the incident was given an International Nuclear Event Scale level 3 categorisation."

2/3 of those will be INES rated.

This is all describing a situation that is substantially safer than most industrial operations I've ever seen. Including many building sites. Try running a building site using granite or a banana plantation with no injuries and no radiation escaping into the surrounding environment; this is a high standard.

Re:The Necessity of Nuclear by NeedMoreTea on Monday October 14, 2019 @12:11AM (#21245220)
To put aside the whataboutism first. Yes I have seen the consequence of coal mining, on both people and place, which is why I am pleased that the UK now has under fifty coal miners, working in a few small scale open mines. From a peak of around 1 million down the mines. Coal is almost completely out of UK generation, and would be with no nuclear. It is presently the source of last resort - the few coal plants that remain spend most of their time idling. By 2025 there will be zero.

If the authorities were able to show an ongoing period of best-practice, excellent management and regulation to ensure the industry (all industry) pays the environmental cost up front from their profit, I'd still be a vocal advocate of nuclear like I was in my naive twenties. No, every time there is systemic ineptness and a public purse left holding the bill for the after-closure clean up. Decades of renaming, cover-up, lies, official inquiries and ignoring the locals. Many of whom are like me - they'd love to accept it and perhaps work there were it not so criminally inept. Same would go for an explosives plant. :p

Have confidence in a reprocessing plant that was going to make the UK billions of good Thatcherite pounds reprocessing the world's nuclear waste, that caused an international outrage, and has not actually made profit if you include the large leak and decomissioning cleanup. In fact even if you discount cleanup THORP looks pretty questionable as to whether it was really profitable at all.

The UK is a small place, a major accident or Chernobyl scale catastrophe would be easily and rapidly nationwide as guessing, Sellafield is perhaps 300 miles as the crow flies from London - maybe 400 by road. I'm maybe about 40 or 50 miles straight line from the plant - it's 80 or 90 by road. A major sea incident would be similar. No one in the UK can get further than 70 miles from the sea.

Authorities say it is safe, neighbouring country Ireland and others in Europe have been campaigning against Sellafield for decades. Not just nuclear activists that you would dismiss, but they have made governmental approaches at diplomatic level and within the EU. That's been because there have been countless incidents, reports of malpractice, official reports and public inquiries of lies and cover ups, and two or three official renamings so we'd forget about the scandal of the Windscale fire, or Seascale. This seam is so rich I am not going to mine it for you. That's all on top of the couple of dozen International Nuclear authority reporting incidents that must be reported. Extensive history of (inadequate) fines too.

The TL;DR is Seascale / Windscale / Sellafield is a Western gold standard for how not to do it. It would take considerable evidence and persuasion for me to have faith and confidence in say the USA or French nuclear management competence. I'm entirely prepared to believe there is someone, somewhere doing it with excellence, but capitalism and communism appears to rule that out, so um, where now?

Authorities lie, seagulls get cancers too, and there are superfund everywhere you find a nuclear industry.

Temporary storage on site is a very bad idea. Leaks, non uniform site security, drums that were designed for a few decades now being called to serve for a century.

Either have long term storage, or drop nuclear. There’s no in between

> Authorities lie, seagulls get cancers too, and there are superfund everywhere you find a nuclear industry.

So based on information that you don't have but assume exists there is a problem? There is actual evidence of known problems that nuclear solves. Like air pollution from coal.

I don't want to sound unsympathetic, the government does lie and I also subscribe to a couple of out-there conspiracy theories. It is just there is a lot of evidence that the nuclear threat is way overblown.

You could move them in to new decade-long storage once a decade. As mentioned, those are small ponds. The world is not made up of absolutes.

We do have evidence, and we have a distinct pattern of behaviour from the many public inquiries and investigations into the standard of management at Seascale / Windscale / Sellafield / THORP.

To be glib, that's why there were so many renamings. To bury the inept history.

And burn coal instead, spread heavy metals and CO2 around and slowly poison everyone.

That is the alternative, we saw it in Japan after the Fukushima accident. Oh, btw, Tepco has announced it will discharge further nuclear contaminated water in the ocean as they ran out of space to store it.

Re:The Necessity of Nuclear by MertsA on Monday October 14, 2019 @12:38AM (#21245300)

Like the trace amounts of Uranium in coal. And don't forget the Radon that comes up with natural gas either. For added fun, Radon is a noble gas so good luck economically removing it as opposed to just venting it all into the atmosphere.

Re:The Necessity of Nuclear by petre on Monday October 14, 2019 @02:18AM (#21245654)
The main concern are arsenic and mercury which accumulate in bottom feeding sea critters some of which we eat (mainly shellfish and shrimp). The uptake of uranium are thorium in marine species is rather low, but yes, burning coal also spreads radiation. Some of the byproducts of nuclear fission (I131, Sr90) are more dangerous because they tend to stick around in our bodies. Uranium and thorium get excreted but the first one is also toxic.

Of the two Radon isotopes, one has a half life of 55 seconds, the other 2.5 days. The main problem are its decay products: Pb210, Bi210 and Po210. It's better to vent it off into the atmosphere than to let it accumulate in mines and basements.

Re:The Necessity of Nuclear by MertsA on Monday October 14, 2019 @12:36AM (#21245291)
Care to point out a couple of those superfund sites? The only ones I'm even familiar with are the Hanford site and Savannah River which were military sites producing nuclear material for nuclear bombs and ICBMs. Hardly comparable to the limited processing that goes into fuel preparation for nuclear power plants, especially considering that fresh fuel is only weakly radioactive and requires no shielding at all between the fuel and the technicians wearing dosimeters all the time.
Re:The Necessity of Nuclear by petre on Sunday October 13, 2019 @11:35PM (#21245078)
The open air storage pond in not ok, but I think the fuel fire scenario is greatly exagerated. I'd have gas masks and plastic suits for family members just in case the site needs to be evacuated. Probably not but it doesn't hurt to at least be prepared.

Re:The Necessity of Nuclear by TeMPOraL on Sunday October 13, 2019 @05:02PM (#21243007)
Nuclear waste is really non-issue, especially compared to what it could help replace - for instance, sludge that comes from oil sands extraction processes, which is equivalently toxic, but there's orders of magnitude more of it, and it's in liquid form, making it much more difficult to handle.

(Sure, to be fair, uranium mining isn't particularly eco-friendly either, but AFAIK even if you count that in, nuclear still comes on top.)

Re:The Necessity of Nuclear by jacquesm on Sunday October 13, 2019 @05:11PM (#21243069)
Nuclear waste - rather than a non-issue - is a giant issue. The amount of nuclear waste is only increasing, our ways of dealing with it for the longer term - say up to the next 500 years - do not stand up to scrutiny and there is a fair chance that we will end up with numerous sites that make your average Superfund site look like Disney Land.

In France, the UK, Japan and the United States there are dumps of radioactive waste that are off-limits for the next couple of centuries. Alternatives have been suggested (such as - ridiculous - shooting the waste into space or dumping it into the deepest parts of the ocean). But none of those are even remotely viable or politically or socially acceptable.

As for the waste from fracking and tar sand processing, yes, that's terrible and it should stop. But nuclear is not the only alternative there.

Re:The Necessity of Nuclear by TeMPOraL on Sunday October 13, 2019 @05:44PM (#21243311)
To my knowledge, the actual amounts of nuclear waste are not that big at all. [0] is a biased source, but taking its number of 34,000m³ of high-level nuclear waste worldwide per year, that's just a 32x32x32m cube of waste per year, without even considering potential reprocessing. It's surprisingly little. Investing in nuclear as a part of the solution to climate issues and energy security would initially raise this amount (which would still remain very small), but would also enable deployment of waste reprocessing technologies that would eat into this considerably.

> In France, the UK, Japan and the United States there are dumps of radioactive waste that are off-limits for the next couple of centuries.

Couple of centuries really isn't much. Industrial waste is problematic on the same timescales, and there's orders of magnitude more of it.

> Alternatives have been suggested (such as - ridiculous - shooting the waste into space or dumping it into the deepest parts of the ocean). But none of those are even remotely viable or politically or socially acceptable.

There's a catch-22 in here. We know how to deal with nuclear waste, but can't implement it because the industry is underfunded, because people are afraid of nuclear waste.

(1) You're linking to a site that is not exactly objective, I would assume the 'world nuclear association' to be somewhat biased in their information.

(2) The problem isn't just the 'high level' nuclear waste, it is all nuclear waste.

But let's just assume that that 34000 cubic meters is all off the problem. And let's assume that you need to store it for 1,000 years and that you're going to make 100% of your electricity baseload using nuclear. Right now, at roughly 10% that's 34000 so for 100% you'd then need 34000x10x1000 cubic meters of storage.

That's a cube 700 meters on it's side. And because of the nature of the waste you can't just stack it that close, you're going to have to space it out and you're going to have to cool it because that much nuclear material is going to output a very large amount of heat.

You're making this all look way easier than it really is.

Re:The Necessity of Nuclear by TeMPOraL on Sunday October 13, 2019 @06:34PM (#21243656)
Yeah, I've mentioned that it's a biased source. It's what I could dig up the fastest that gave the amounts of waste in units of volume, and the value is in the ballpark of what I remember reading elsewhere.

That 700m cube is still, in other words, ten thousand 30m cubes. Even accounting for spacing things out, that's on the order of magnitude of a large city. A single city made of high-level waste, in exchange for running 100% of today's energy needs on nuclear for thousand of years[0]. That's, again, not much relative to all the other kinds of waste we're creating. And in reality, it would be a city made of fuel for a different type of reactors.

There's a few times more of mid-level waste, which is another thing potentially worth caring about. Rest of the waste is considered low-level and is either buried or enters regular waste management pipeline.

I'm not saying nuclear waste is not a problem, just that it isn't particularly special compared to other types of highly toxic industrial waste. There's not much of it by volume, unlike most other waste it actually becomes less dangerous with time, and there are ways to put it to use that are blocked pretty much only by people saying nuclear waste is a big issue.

[0] - Or, eyeballing the doubling time of 2.5% growth rate, something like 150 years of 100% energy at current energy use growth.

Re:The Necessity of Nuclear by jacquesm on Sunday October 13, 2019 @06:46PM (#21243757)
Let me tell you a little story. There is an area North of Amsterdam, where they stashed some by-products of the Agent-Orange production during the Vietnam war.

2-4-5T and a bunch of other nasties (Dioxins). That's bad industrial waste, not radioactive but still, you really don't want it near your village or water supply.

Those vats were stored there at the end of the Vietnam war and conveniently forgotten (by Philips Duphar). It was only about 10,000 barrels of junk, a very small fraction of your initial 32x32x32 meter cube, less than 10%.

It took decades to clean it all up, and some parts of it will never be cleaned up because we can't dig deep enough. Because in the meantime the Dioxin had made it into the groundwater plume, the damage of which will not be known for another couple of decades.

If that had been radioactive waste they wouldn't have been able to do much about it for another couple of hundred years.

I don't follow your push to minimize this problem, it is a huge issue and just thinking of a 'a single city made of high-level radio active waste' makes my skin crawl. Such a place should not exist, and the Philips-Duphar story should give you at least one datapoint on why burying stuff and letting future generations deal with it so we can have our perks today is not - in my opinion - a viable strategy.

Energy is a great thing but we are not lacking for energy at all, it's raining energy continuously, we are awash in it. But just like with a rain of soup, if you bring a fork you're not going to do much.

Re:The Necessity of Nuclear by TeMPOraL on Sunday October 13, 2019 @07:16PM (#21243939)
Let me counter that story with observation that there's something on the order of 500 000 tons of high-level nuclear waste currently stored by countries worldwide, and so far they manage. Point being that it can be handled responsibly. It probably wouldn't be the best idea in a perfect world, but we are kind of in a hurry right now, with every year of still being on fossil fuels adding to severity of future consequences.

My push to "minimize" this problem is a push towards recognizing that the problem is manageable in practice. The image of "single city made of high-level waste" was meant to picture just how little there is to manage, by volume, and once again - most of that we already know how to use as fuel; we just can't, because appropriate reactors aren't being built, primarily because people are afraid of the waste.

We may be technically drowning in energy from the Sun, but we're still not fast enough with making use of it. In the meantime, we have the closest thing after fusion to an energetic magic bullet - very high density, clean energy source with manageable waste - and we've been mostly sitting on it for decades now.

But maybe at this point it's really too late, maybe by the time enough reactors could come on-line, there really would be enough renewables to take over. It's unclear to me at this point whether the recent growth of solar and wind capacity is sustainable.

Re:The Necessity of Nuclear by jacquesm on Sunday October 13, 2019 @07:23PM (#21243972)
> so far they manage

Yes, by doing not much of anything and only across a very very short span of time compared to how long it will have to work eventually. That's a bit like saying that the landmine you are sitting on hasn't gone off yet. True, it hasn't. And it may never go off. But it is still a landmine and it is still quite dangerous. If you had the choice between not having a landmine to sit on in the first place vs sitting on one to keep it safe which would you take?

Re:The Necessity of Nuclear by TeMPOraL on Sunday October 13, 2019 @07:30PM (#21244020)
Of course "no landmine". But I'm not convinced yet we have that choice - that renewables really are growing fast enough and sustainably enough for there to be no point in building up nuclear capacity.
Re:The Necessity of Nuclear by jacquesm on Sunday October 13, 2019 @07:39PM (#21244077)
We've sunk untold billions into nuclear, a very small fraction of what has gone into renewables. The major reason why so many countries wanted to have nuclear reactors was mostly because it was convenient cover for weapons research, and a way to make fissile material for weapons (Plutonium, for instance), not because it made clean or commercially viable energy.

France is a perfect example of this. When the oil crisis hit in the 70's they then used this knowledge to rapidly expand their use of nuclear power, which is now the highest in the world. But the reactors are aging, the waste is piling up and new construction has been delayed or halted indefinitely (and is already over budget).

Whether renewables are growing fast enough is something we control in a very direct way, and cranking out windmills and solar panels is really a mere matter of engineering. The latest iteration windmills make impressive power (8 to 12 MW design power is now a reality, something I did not expect to see in my lifetime), and can be mass produced economically.

They also tie into the grid at many locations, something aging grid infrastructure appreciates (the variability is another problem, but there are fortunately some solutions for that now).

Out of curiosity, is there a good estimate for how much money the world has spent on nuclear/renewable energy research? You'd think this information should be easy to find given the importance of the nuclear vs renewables debate, but it's not obvious to me how to find it.

Re:The Necessity of Nuclear by jacquesm on Monday October 14, 2019 @04:14AM (#21246113)
Most of the money spent on nuclear research is spent on fusion projects and things like pebble bed reactors, most of this is in the proof-of-concept or early production stage and funded by governments.

Most of the money spent on renewables (solar, wind) is spent on scaling up and (boring, but necessary) production. Some (tidal, geothermal) has gone into proof of concept level projects. The amounts specified vary greatly based on the source.

ITER alone (originally projected to cost $5B) already clocks in at $20B and doesn't seem to be much closer to something resembling a working prototype than it was several years ago.

It’s the other way around. If the money poured into renewables had gone to nuclear there would be no climate crisis.

That's a very bold statement for which I have seen absolutely no proof. Solar and wind do not have the long term waste issues associated with nuclear and cost a small fraction of nuclear per installed Watt of power generation.

There is no significant difference in CO2 output of nuclear vs solar or wind so you'd have a climate crisis just the same. If you're looking to displace fossil fuel with nuclear you're going to have to look much further than just electricity, and solar and wind are just as good or even better at that as nuclear power is. Working fusion would be better than all of these options, but unfortunately we don't have it.

> There are 9 countries with nukes and 31 with nuclear power. The idea that nuclear power plants were build to acquire nukes seems unlikely.

It may seem unlikely to you but it is a well established fact. France, China the United States, Russia and the United Kingdom, some of the earliest nuclear powers all got into the nuclear plant game to make weapons grade material. The power generated was a by-product. Countries that got into the game later and that did not have access to nuclear technology were licensed 'safe' tech that could not be used for enrichment.

Iran and North Korea are only interested in nuclear power for weapons purposes, everything else is just a fig leaf.

You got that exactly backwards. These five states all used production reactors to make their weapons Pu, which didn't produce useful power. Only later did they build power reactors, which don't produce weapons grade Pu.

Do you honestly think, Germany, Japan, Canada, Sweden, Finland, S Korea, Czechoslovakia etc. are/were also only interested in nuclear power as a cover for their weapons program?

However there would be far fewer storage sites where that risk would be occurring. Compared to the number of incidents caused by the chemical and fossil fuel industries on any time scale, and the hypothetical risk of small areas of contamination far outweighs the level of global contamination that is going on today (most of which isn't being acknowledged, let alone cleaned up).
Re:The Necessity of Nuclear by jacquesm on Sunday October 13, 2019 @07:20PM (#21243962)
You're going to run straight into 'NIMBY' and other political constraints for your eventually designated storage sites. I'm sure someone will find a way to argue that we should send it to the third world as long as we get to control the burial sites on account of proliferation worries. We've already done this with many other kinds of waste.

In the end it isn't about the area directly affected in the near future, it is about the long term effects and those are very hard to model accurately when it comes to massive deposits of nuclear waste.

Just a couple of the risks: massive terrorist target, risk of pooling, risk of large scale groundwater contamination, risk of the whole thing blowing up. These are not trivial and not all of them can be dealt with over the time-scales that the waste would still be significantly radio active.

Political structures are not stable across the time-scales that you are looking at here, you might end up seriously regretting any particular site a few hundred years into the future.

While for many decades all things nuclear, not just weapons but also energy production, saw massive funding and hype all over the world.

People thought nuclear would be used for anything from moving earth to powering the jetpacks they'd use to fly to work, they thought we'd be running out of uranium because every country would have hundreds and thousands of nuclear reactors.

Why ain't we living in this amazing future now? Because it turned out nuclear isn't all that economical and practical as we originally believed it to be.

I don't agree with this position, for what it's worth.

Wasn't global warming supposed to be critical in the next 5 years?
Re:The Necessity of Nuclear by DiogenesKynikos on Monday October 14, 2019 @01:31PM (#21250678)
Which global warming impact is critical in the next 5 years? For climate, 5 years is nothing. It's difficult to even see the temperature trend over such a short timespan, given noise sources like El Niño that have periods of several years.

You'll have to wait longer in order to really see the effects of global warming, as far as I understand it.

Re:The Necessity of Nuclear by Kaiyou on Tuesday October 15, 2019 @03:49AM (#21256376)
I'm a global warming skeptic myself, but have been told that we need to take action within the next five years or else it will be too late. But I've been hearing similar things for the past 30 years, so I take it with a grain of salt.
Re:The Necessity of Nuclear by TeMPOraL on Tuesday October 15, 2019 @08:21AM (#21257648)
Emissions are growing exponentially, and are accumulative. When you look at the CO₂ footprint graph, the damage done to the climate is essentially proportional to the area under the curve. What 30 years ago was just a concern of some scientists, today is becoming visible to people, and 30 years from now will be obvious (under current growth, between today and 30 years from now, we'll have emitted more CO₂ than we had between today and the dawn of mankind - a "neat" feature of exponential growth).

In the real world, exponents don't last forever. The economy will eventually give in, the question is how. 60 years ago the bet was that we'll run out of resources to burn. Today, the consensus is that we'll most likely destabilize the climate to the point of total civilizational collapse before we exhaust economically exploitable fossil fuel deposits.

As for the next years being critical in determining how the world will look like many decades from now, keep in mind that the damage CO₂ is causing is proportional to the integral of the yearly emissions curve, and also that feedback loops take time to settle at a new equilibrium. Models predicting average temperatures and sea levels take into account that even when we become completely net carbon neutral, the already accumulated CO₂ will still warm up the climate for decades. So it very much matters when we get to carbon neutrality, and the sooner we get there the (exponentially) better.

Re:The Necessity of Nuclear by Kaiyou on Wednesday October 16, 2019 @08:51AM (#21269784)
So it's within the next 50-100 years and on the list of things we should be worrying about.
Re:The Necessity of Nuclear by nickik on Monday October 14, 2019 @03:35AM (#21245977)
The whole nuclear waste of the last 50 years of french nuclear fills a couple of buildings. The volumne is really not a problem at all.

We could fuel the whole world with nuclear fuel and not have any significant issue with nuclear waste storage.

Specially if we are moving to more modern reactors who can consume the current nuclear waste and massivly reduce the volumne (something we should manage over the next 500 years I'm sure).

In fact with modern reactors you can get to a point where you only have 300 years of storage requirment until it hits background radiation.

And even if you want a 1000s of year solution, we can absolutly build those already and its not really all that much of a technical issue. As has been done in Finland I believe.

In the US this might make people "feel bad" but it's not a real problem. In the southwest there are unimaginably large deserts where no one lives and no one ever will live. A lot of it is federal government property and has been used for nuclear bomb testing in the past precisely because it is land that no one will ever care about. See: Yucca Mountain nuclear waste repository.

Nuclear waste - rather than a non-issue - is a giant issue.

Bigger issue than global warming? It seems that's what environmentalists think.

Re:The Necessity of Nuclear by jacquesm on Monday October 14, 2019 @03:54AM (#21246049)
Global warming is also a huge issue. But there is no direct line between 'global warming is a huge issue' to 'we should therefore ignore the issue of nuclear waste and go all in on nuclear'.

The nuclear lobby is seizing on climate change to push through an agenda that would not stand a chance otherwise, and I refuse to have the wool pulled over my eyes. If we go into this we need to readily acknowledge the problem and budget for it accordingly. This will - at present, barring new developments - price nuclear as it is today right out of the equation compared to the alternatives.

Solar and wind have become viable alternatives, tackling baseload using them is still tough but getting better every day with new developments in short term storage and transmission line technology.

Re:The Necessity of Nuclear by GhettoMaestro on Sunday October 13, 2019 @05:24PM (#21243160)
Yeah the ideas of shooting into space or dumping into ocean are really asinine. It is a complex issue (waste storage).

We (the US) had a decent plan with the planned Yucca Mountain storage facility. But, you know, politics.

I’m contrast, all the lead we’ve scattered around the soil is a problem forever. (Lead is an element. It does not decay. All forms are toxic to varying degrees.). Various polymer waste and other petroleum and coal waste are, as far as I know and until new bacteria evolve that can eat it, problems forever.

The fact that nuclear waste decays is a win.

I think this is generally true, but poor storage and processing at a couple of early sites (I’m thinking Hanford in particular) have had negative effects on the communities.
Re:The Necessity of Nuclear by dilippkumar on Monday October 14, 2019 @03:02AM (#21245823)
I’ve always thought of nuclear waste as a thinly veiled euphemism for Plutonium.

Plutonium is an unavoidable product of U235 fission - and can be extracted from the resulting “nuclear waste” by chemical processes.

Having seen stuxnet, I’m convinced that there’s a lot of investment in preventing people from gaining access to U238. Starting from Uranium ore, getting to Plutonium would be much simpler than getting to sufficient quantities of U238 and have the benefit of generating energy along the way. Additionally, Plutonium based bombs have a “higher yield” according to what I’ve read.

I wonder if USA and Russia agreed to limit Plutonium production- and that’s the real reason behind severely limiting nuclear energy.

Re:The Necessity of Nuclear by chipsa on Monday October 14, 2019 @06:12AM (#21246616)
There's different types of plutonium that's made. Bombs are made from Pu-239. But reactors will normally produce Pu-240 as well, unless you specifically design your reactor and fuel it appropriately to produce mostly Pu-239.

So what's the difference? Pu-240 is hot. It's too radioactive to make bombs out of, because you'll end up cooking your workers. And because it's so similar in weight to Pu-239, you can't effectively separate it out.

”It seemed such a good idea at the time. At least, to the German politicians in charge.

But in hindsight, the Asse II salt mine should never have been used in the 1960s and 1970s as a site to dump nuclear waste, said Ingo Bautz of the Federal Office for Radiation Protection.”

Because it doesn’t store highly radioactive waste, it isn’t _that_ much of a concern, but it started leaking ten years into operation. That, IMO, is a concern, as it indicates sloppiness.

Re:The Necessity of Nuclear by freeflight on Sunday October 13, 2019 @07:05PM (#21243868)
What makes it even more absurd is that storing in a salt mine was considered the "best option" back then, backed by a scientific consensus.

That consensus came out of an international conference in the 50s in, I believe, Beirut. Asse II was supposed to be one of the experimental sites to prove the theory, but over the decades ended up being run much more like a "general dump" with extremely lackluster documentation habits.

Re:The Necessity of Nuclear by didbfkf on Sunday October 13, 2019 @08:53PM (#21244410)
There have been uncountable leaks!

Storing nuclear waste is very tricky. It changes chemically due to the atomic decay, so you have to figure out a container that is stable against scores of different chemicals in many concentrations.

On top of that, it’s emitting heat so the container can’t be too big otherwise it’ll melt.

Then the waste evolves gases, some radioactive, that make the pressure build up.

Then your container is getting bombarded by alpha rays which wedges itself between the grain boundaries and embrittlement the container.

It’s a bloody (and expensive) mess!

Re:The Necessity of Nuclear by 08-15 on Monday October 14, 2019 @05:59AM (#21246560)
All of this is made up nonsense. Only 14 radioactive fission product isotopes end up in the final waste form, and they are in an inert oxide form. Their decay chains are short and hardly change the chemistry, if anything, it becomes more stable. They also don't produce gasses, much less radioactive ones.

The only kernel of truth is that __if__ you throw out fuel instead of waste, then you get a heat problem over the long term and the container is irradiated by alpha particles. It won't melt, but it might corrode. But why would you throw away fuel?

Re:The Necessity of Nuclear by mlyle on Monday October 14, 2019 @02:46AM (#21245761)
In fairness, the stuff with a half life of 24,000 years isn't that radioactive/scary.

It's the stuff with half lives of 3-300 years that you need to worry about, really.

Compared to its activity a month after being removed from the reactor-- spent fuel loses 90% of its activity in 80 years or so and 99% of its activity in 200 years, at which time it's still about 150x as active as the original uranium ore (which itself is 6x or so diluted, so about 25x as active as the original uranium)

Re:The Necessity of Nuclear by tapland on Sunday October 13, 2019 @05:00PM (#21242989)
Yeah, they should be moved within a few years from pools to sarcophagus style containers. Those containers can later be moved to end storage or wherever without nearly as much hassle as abandoned rods in pools.

Yup. Yucca Mountain wasn't a perfect plan, but it was pretty damn good and definitely much better than the alternative of doing nothing.
Re:The Necessity of Nuclear by nickik on Monday October 14, 2019 @03:46AM (#21246013)
No it wasn't. The US has a perfect place for nuclear waste that we discovered a while ago but politics made it be Yucca Mountain and that is not a good place. And then even worse becuase of politics the technical targets have been moved to absurd demands that make it utterly impossible to move forward.

The US has the right location and the money already stored, there is still the Yuca Mountain inpass as it currently required to be the selected site.

I think finding such a site in the first place is nonsense as in 50-100 years we should be consume that fuel anyway.

Re:The Necessity of Nuclear by blaser-waffle on Monday October 14, 2019 @03:04PM (#21251604)

Re:The Necessity of Nuclear by nickik on Tuesday October 15, 2019 @05:31AM (#21256862)
I can't find the name at the moment but its a structure that has been unchanging for 1000s of years and has been evaluated as perfect for nuclear waste since the very early days of nuclear in the US.

I think it was evaluated at about 1/5 the cost of bringing Yucca Maintain to the same standard.

'Combating climate change: The role of nuclear power' from University of University of Michigan had a number of lectures where some of this is mentioned if I remember correctly.

I'm working so I don't have time at the moment.

Re:The Necessity of Nuclear by Vomzor on Sunday October 13, 2019 @05:37PM (#21243250)
What mess? The waste is being kept in manned facilities and will likely be repurposed in the next 20 years as fuel for a new generation of nuclear reactors. The first commercial nuclear power plant was in 1956. If you think about it, we are dealing with the 'mess' of the previous generation. And we are doing fine.
Re:The Necessity of Nuclear by jacquesm on Sunday October 13, 2019 @06:33PM (#21243646)
No, we're not dealing with it at all. We are just keeping it around because we don't really have a solution. The stuff that was stored decades ago lies mostly untouched, and if it has been touched it is usually because the containment failed and there have been leaks.
Re:The Necessity of Nuclear by Google234 on Sunday October 13, 2019 @07:56PM (#21244177)
The earth is 1 trillion km^3 in volume. I don't get your problem with using 0.00000000003% (that 1000 year estimate of waste from earlier in the thread) of that to store nuclear waste so that we can stop pumping 32.5 billion tons of CO2 into the air every year.
Re:The Necessity of Nuclear by jacquesm on Monday October 14, 2019 @04:46AM (#21246248)

Is nuclear waste even still a problem?

That problem was solved long ago, just reprocess it through breeder reactors and get even more energy!

The problem with the anti-nuclear lobby is that they block progress, then point at 50-year-old problems - that they have blocked implementing the solutions for - as current and unsolvable. They don’t actually want clean power. They want a reversion to a pre-industrial society, with themselves in charge.

That problem is far from solved, as you can see by the near-zero number of breeder reactors currently in activity around the world.

Re:The Necessity of Nuclear by mlyle on Sunday October 13, 2019 @05:33PM (#21243214)
"Weapons grade plutonium" obfuscates that you can make a nuclear weapon from non-weapons grade plutonium, albeit with an increased risk of only getting the fizzle yield.

Nuclear weapons that are "only" a couple kilotons are scary enough for me, kthx.
