So it's just a nuclear plant and has nothing to do with coal?

[-] sonori@beehaw.org 24 points 5 months ago

At first glance I thought it was reuseing the coal plants turbines, but looking though the article the only connection I can find is that it’s located several miles away and the only connection is that it plans to hire a hundred or so people from the coal plant it’s replacing and that Wyoming’s powder river basin is nearby and its associated highly automated low sulfur coal mines are in the vauge area.

All this to say, yes it has practically nothing to do with coal.

[-] Dempf@lemmy.zip 8 points 5 months ago

I wonder if it has to do with reusing the transmission lines from the coal plant.

[-] jjagaimo@lemmy.ca 11 points 5 months ago

Coal plant burns coal to heat water, makes steam, and the steam powers a turbine to produce electricity. A nuclear power plant uses nuclear fuel to heat water and produce steam similar to a coal plant. It may do this indirectly (e.g. second loop between the nuclear fuel and water loop to prevent the water becoming radioactive). This means that to build a nuclear plant you essentially need to build a coal plant, and then also the nuclear reactor and safety stuff, which makes them more expensive. Since coal plants are being turned off anyways, it might be more cost effective to just retrofit old coal plants so the only cost is the nuclear reactor side of things (plus any necessary maintenance and upgrades)

Sounds like it's replacing the neighboring coal power plant.

[-] vinniep@beehaw.org 7 points 5 months ago

I had to dig up some other sources for info, but this is the case. The new plant has nothing to do with coal, but it is being built to replace the power production and local power related jobs in that area.

Oh wow, so even more radioactive waste that will afflict thousands of future generations and the environment for a tiny amount of produced energy now :(

[-] Steve@startrek.website 54 points 5 months ago* (last edited 5 months ago)

Coal plants spread radioactive waste inti the air.

Fission plants leave a hot turd behind, but at least it can be buried in one spot out of reach instead of everyone breathing it.

[-] flora_explora@beehaw.org 12 points 5 months ago

Yeah sure, coal plants obviously have to go. But why not invest in sustainable energy production?

Nuclear waste cannot just be buried, unless you don't care about polluting huge areas with radioactivity. In Germany, there have been decades long debates where to store nuclear waste and even to this day there hasn't been found a good storage for the waste we produced in the 70ies. And this shit costs billions of euros that the company profiting of the plant doesn't have to pay but that in turn society has to pay.

Wyoming is investing heavily in wind even with the understanding that current turbine designs ultimately cost money to repair and operate as opposed to being a solution that pays for itself. The conversion of a coal plant to nuclear is part of a long term strategy to reduce environmental impact. They're taking a long view approach that solar and wind can't in the short term do what they need it to do but that continued use of coal, at all, even just for the short term, is untenable. Meanwhile, Wyoming is ALSO investing in research on using nuclear byproducts to generate electricity. I have a lot of complaints about Wyoming and how chill they are with the alt-right but I have to commend them that their energy strategy for their state basically reflects what we all need to be doing

[-] infinitevalence@discuss.online 7 points 5 months ago

That is simply not true, storage is a solved problem, and the reason for not having locations is a political problem. NIMBY (Not in my back yard) keeps the world from having permanent storage locations, not science.

[-] flora_explora@beehaw.org 3 points 5 months ago

Can you show me any evidence for that? I'm really curious how we could develop a technology to safely store nuclear waste for millions of years. I mean, on that time scale you'd even factor in changes in geology and all kinds of other factors. Sure, there are definitely people who say that "it should be fine". But how can you reliably model geology on that time scale? You simply cannot. So I would definitely disagree with your statement that storage is a solved problem.

[-] infinitevalence@discuss.online 7 points 5 months ago* (last edited 5 months ago)

Honestly yes! I made a strong bold statement its only fair to ask for references.

So here are a few general video's along with a few interesting papers regarding storing HLW as/in glass-ceramics. The academic research and discussion of this immobilization methods is very robust so lots of stuff you can read on that subject.

BUT we dont have to store Fission HLW if we reprocess it and run it in conjunction with other reactor types like LIFTR. Much of the remaining waste produced in currently operating reactors is still mostly unused and at most 5-10% of the total material is used up. We can pass that through a breeder reactor and convert U238 to P239 which turns "useless" naturally occurring non fissile uranium into fissile plutonium.

So, my point is that assuming we keep using low enrichment uranium to power current BWR/PWR reactors we have an existing solution for the waste (which if ALL of the worlds HLW was combined would not even fill a professional stadium) that easily takes care of all the waste created since we started production.

BUT all that waste is actually fuel if we recycle/reprocess it and we can burn up another large percentage of that waste and its remaining elements are generally shorter lived forms of waste.

Thanks for all the informative sources. First of all, I think you are probably right that it is a political or rather economic problem, not necessarily a scientific one. Capitalism doesn't give any incentive to care for the environment or to recycle anything if it isn't profitable. And politics are heavily influenced if not driven by capitalism.

But then, seeing the various articles you provided about nuclear waste storage, I didn't really get the impression that it is a solved problem. Sabine Hossenfelder spends a very long time talking about what nuclear waste is but only mentions problems with storage for hundreds of thousands of years for a very short time. And also Elina Charatidsou doesn't even mention potential problems of geological changes etc. And the facility she is presenting is still in the research stage. So where are the solutions for a long-term storage that guarantees safety? Nuclear waste may not be as problematic as it is made out, but real solutions look different to me.

Very interesting also the point about recycling nuclear waste. I haven't even heard of it and it sounds like a really good thing to do. We'd still have very high costs handling and storing it, but only for a few hundreds of years at least. Although it seems like actually applying this is still not really planned by most countries and even then the problem of nuclear waste doesn't go away fully.

[-] Steve@startrek.website 5 points 5 months ago

I see fission as a transitional technology, like CFL light bulbs vs LED lighting.

The transition has been struggling for 60 years for political reasons.

[-] flora_explora@beehaw.org 1 points 5 months ago

Yes, I get that. But I think we should just keep in mind that it is no sustainable or long-term solution. Since many people have started talking positively about nuclear energy in the last few years, I think it is important to remind everyone of the problems that arise with it.

[-] HobbitFoot@thelemmy.club 2 points 5 months ago

It is a lot harder to get wind to turn a coal power plant turbine.

[-] infinitevalence@discuss.online 11 points 5 months ago

You forgot all the heavy metals too! Lots of brutal heavy metals in coal emissions and waste, which we dont get even in low level fission waste.

[-] theangriestbird@beehaw.org 4 points 5 months ago

This was posted in c/Environment yesterday. I bring that up to point you over to that thread, where @Powderhorn@beehaw.org had some great insights into why this move is more regressive than it sounds.

[-] sabreW4K3@lazysoci.al 2 points 5 months ago

So originally I wasn't federated with !environment@beehaw.org so couldn't read the post, I've now read it and can understand everything I didn't before. It's disappointing. But I'm glad that wave power was mentioned as I think that will be huge in the coming years. Hopefully it's not as far off as @Powderhorn@beehaw.org suspects. I feel like with ground source heat pumps, we have heating sorted, but we're still looking for solutions in power and wave seems the obvious solution.

[-] Powderhorn@beehaw.org 3 points 5 months ago

It's an investment problem. No one is doing scalable wave power because the money is in offshore wind.

[-] sabreW4K3@lazysoci.al 1 points 5 months ago

Such a shame given how much water covers the surface of this planet
