Totally. Tinpot dictators getting nukes is nothing to worry about. And the waste can just be handwaved away. After all, they have a storage facility in Finland that will probably come online in a couple of years. Problem solved.

PhobosAnomaly ,

The waste is a fair point - storage isn't a long term solution but then I suppose it can be managed in the interim, not like the effects of climate change.

I'm not seeing your point of "nukes" though?

Diplomjodler3 ,

More nuclear plants means more capacity and diversification in supply chains, i.e. it's easier to acquire technology and supplies through dark channels. That will lead to more proliferation. Where do you think North Korea got its nukes? The answer is Pakistan, by the way.

Honytawk ,

I still prefer 47 grams of nuclear waste over 1950 Kg of coal pollution in the air.

That is for the same amount of energy.

traches ,

Cost billions and have 10 year lead times?

Lmaydev ,

We're reaching the point where discussing cost in regard to the energy crisis makes us look like fucking idiots.

Imagine what kids reading the history books are going to think of these discussions.

And 10 years isn't that long really. If someone said we could use no fossil fuels in energy generation in 10 years time that doesn't sound long at all.

mormund ,

Cost is a proxy for productivity and resources. So while it is stupid to say that the energy transition is too expensive, shouldn't we rather invest our productivity and resources into a faster and cheaper solution? Drawing focus away from renewables is dangerous as others have mentioned, because it is too late to reach our goals with nuclear.

suburban_hillbilly ,

shouldn’t we rather invest our productivity and resources into a faster and cheaper solution?

We sure should. Do tell of this this faster, cheaper solution that is also adequate to meet all of our needs.

suburban_hillbilly ,

Really gives me the warm fuzzies when someone looks at changes to physical systems over time then draws a trend line into the future indefinitely without any citations or discussion of plausibility for the part they drew on.

Aurenkin ,

Which part specifically do you take issue with? It's a bounded timeframe with over 60 references. We're already 4 years into their predicted trends and on track so it seems like they are into something.

suburban_hillbilly ,

All the charts on page 15. The ones where they extrapolate exponential improvement for a decade while only citing themselves. Their prediction is 15% annually for storage cost improvements in Li-ion batteries which they call 'conservative'

Our analysis conservatively assumes that battery energy storage capacity costs will continue to decline over the course of the 2020s at an average annual rate of 15% (Figure 3).

Let us check if their souce updated. $139 for 2023? That isn't a 15% decrease since 2019's $156, let alone year over year since then, which would be under $90. In spite of last year's drop that is still more than the 2021 price of $132. I don't know what 'on track' means to you but it must be something different than it means to me.

Aurenkin ,

Thank you, appreciate you showing specifically what your issue is. I agree the timeline for the battery costs hasn't worked out exactly because of some anomalies over the last year or two but the trend is sharply down again. So it seems like we are on track to achieve a cost of around $90 by 2025 now rather than 2024 at least according to Goldman Sachs.

If your issue is with the exact timeline, I say that's fair enough, but being off by a year with battery costs isn't too bad I don't think. Of course as with all forecasting we'll have to see exactly how it pans out in reality but it's a pretty big risk if you want to start building a nuclear reactor now, factoring in construction time plus payback period.

someacnt_ ,

Why do they do this? The battery companies would want compensation, too!

Lmaydev ,

No I don't think so. Nuclear is super effective and consistent, especially for large setups.

Using renewables while we get our nuclear up makes complete sense. And subsidising nuclear with renewables after that also makes sense.

But the technology to rely entirely on renewables isn't really there either.

frezik ,

But the technology to rely entirely on renewables isn't really there either.

Yes, it is.

https://books.google.com/books/about/No_Miracles_Needed.html?id=aVKmEAAAQBAJ&source=kp_book_description

This is a book by a professor of Civil and Environmental Engineering that goes into the details. We don't need nuclear. All the tech is there.

Imgonnatrythis ,

Yes. Should have started more 10years ago, but doesn't mean don't start now.

deegeese ,
@deegeese@sopuli.xyz avatar

If you start building a new nuclear plant today, it’ll start generating power around the year 2045, by which time renewables with storage will have gotten even cheaper.

Bet you the public will be on the hook to pay for that white elephant because utility companies privatize profits and socialize losses.

someacnt_ ,

Why do you assume it takes that long? Are you assuming US circumstances?

deegeese ,
@deegeese@sopuli.xyz avatar

That's how long they actually end up taking to build.

Look up the project history of your local NPP and see how long it was from planning approval to putting power on the grid.

someacnt_ , (edited )

It says it took 60 months on average.
I guess from approval, it often took 8 years, so a decade makes sense.

deegeese ,
@deegeese@sopuli.xyz avatar

Which country builds a NPP in only 5 years, China?

someacnt_ ,

South Korea

frezik ,

Except we have better options than we did 10 years ago.

I'd be all for nuclear if we rolled back the clock to 2010 or so. As it stands, solar/wind/storage/hvdc lines can do the job. The situation moved and my opinion moved.

someacnt_ ,

Wdym 10 year lead times?

elfahor ,

There are two main problems in my opinion, and they are both related to the "fuel". First, uranium is rare and you often need to buy it from other countries. For instance, Russia. Not great. Second, it is not renewable energy. We can't rely on nuclear fission in the long run.
Then there's also the issue of waste, which despite not being as critical as some argue, is still a problem to consider

Kidplayer_666 ,

Uranium is not that rare. Doesn’t Canada have quite a bit of it? Portugal used to mine it too, as well as several countries in Africa

bassomitron ,

Yeah, countries obtaining uranium really isn't that big of an obstacle.

FireRetardant ,

A big problem IMO is the generational responsibility of the waste as well. There needs to be decades of planning, monitoring and maintaince to ensure waste sites are safe and secure, this can be done but modern political climates can make it difficult.

Thorry84 , (edited )

Agreed, dealing with the waste is a thing. But for me a solvable problem and something that doesn't need to be solved right away. We currently store a lot of nuclear waste in holding locations till we figure out a way to either make it less radioactive or store it for long enough.
The alternative however is having coal plants all over the world spew all their dust (including radioactive dust) and CO2 straight into the atmosphere. This to me is a far bigger issue to solve. It isn't contained in one location, but instead ends up all over the world. It ends up in people's homes and bodies, with a huge impact to their health. It ends up in the atmosphere, with climate change causing huge (and expensive) issues.

The amount of money we need to handle nuclear waste would be orders of magnitude lower than what we are going to have to pay to handle climate change. And that isn't even fixing the issue, just dealing with the consequences. I don't know how we are ever going to get all that carbon back out of the atmosphere, but it won't be cheap.

Eczpurt ,

It'd be nice to prioritise it at least rather than tucking it away under the oil and gas rug. There is no real competition in energy output to a nuclear power plant. And despite its egregious up front cost, operating it is relatively low cost.

In regards to fuel, uranium is used often but there is options such as thorium that have been used with some success. I do agree it is unfortunate to have to purchase from other countries but I think it beats buying natural gas from wherever it may be sold.

ShouldIHaveFun ,

There are some reactor designs that run on waste of standard reactors. It would solve two of your points for at least some decades.

saltesc ,

you often need to buy it from other countries. For instance, Russia. Not great.

Yeeeeah, I wouldn't worry about that. Sure we (Australia) are conservative with our fears of mining and exporting uranium, especially with the Cold War and reactor whoopsies around the world. But historically it doesn't take much for us to go down on an ally.

https://lemmy.world/pictrs/image/1a7262cd-836b-4f40-8038-05cc2a2e17c0.png

Just let us finish unloading all our coal off to the worst polluting nations first, then we'll crack the top-shelf stuff.

Mrs_deWinter ,

Is that supposed to convince me that there's plenty of uranium left? Because based on the numbers shown with reserve vs. historical usage it kinda seems like it would last for a few decades at best.

Wxnzxn ,
@Wxnzxn@lemmy.ml avatar

The mining is also usually a really polluting affair for the region, much more than the what power generation might suggest. And overall, in many countries there is a lot of subsidies going on for hidden costs, especially relating to the waste and initial construction. So it is not as cheap as a first look might suggest.

I'm not against it per se, it is better than fossil fuels, which simply is the more urgent matter, but it's never been the wonder technology it has been touted as ever since it first appeared.

EldritchFeminity ,

One thing to remember about the mining issue is that coal mining is just as bad, and coal is often radioactive as well. More people have died from radiation poisoning due to coal power/mining than have died from radiation poisoning due to nuclear power, even when you include disasters like Three Mile Island and Chernobyl.

Of course, we've also been mining and using coal a lot longer, but the radioactive coal dust and possibly radioactive particles in the smoke from coal plants is something that many people are unaware of.

But, like you said, the big thing is to move away from fossil fuels entirely, and nuclear power has its own issues. It doesn't so much matter what we go with so long as we do actually go with something, and renewables are getting better and better all the time.

Tlaloc_Temporal ,

Coal has caused more deaths this year than the entire history of nuclear anything has in total. This includes nuclear energy, nuclear research, nuclear medicine, nuclear irradiation (food storage), and too many orphan sources.

winterayars ,

Uranium isn't the only possible fuel. It's just the one we've been using (because it's the one that lets you make nuclear weapons).

someguy3 ,

Buying uranium from Canada and Australia? Inconceivable!

yogthos ,
@yogthos@lemmy.ml avatar

Except that you don't need uranium for nuclear reactors. The reason it's used traditionally because it's also used for nuclear weapons. Thorium is a much better fuel that's more abundant. China has already started operating these types of reactors. The other advantage of this design is that they use molten salt instead of water for cooling. Molten salt reactors don't need to be built next to large bodies of water, and they are safer because salt becomes solid when it cools limiting the size of contamination in case of an accident.

https://www.world-nuclear-news.org/Articles/Operating-permit-issued-for-Chinese-molten-salt-re

someacnt_ ,

That's why we need fusion, which will use a lot of the same tech.

Tlaloc_Temporal ,

I don't think it will. The large cost of a reactor will probably be shared, but fission plants don't deal with plasma, magnets, hydrogen/helium storage, lasers, or capacitors. And we don't even know the method by which a practical fusion plant will operate!

someacnt_ ,

I am talking in the sense that the same companies are participating in fusion research, and pretty sure the methods you mentioned are utilized somewhat in nuclear plants. Like handling and filtering radioactive materials.

Tlaloc_Temporal ,

Radioactive waste maybe. Fusion plants are likely to create irradiated parts that degrade quickly, similar to fission plants. Fusion fuel on the other hand, is gaseous, and likes to escape. Hydrogen is explosive, while helium-3 is just expensive.

Captain_Baka ,

"Safe". Yeah. Let's talk about Chernobyl, Three Mile Island and Fukushima. All that was kinda not so safe, don't you think?

BachenBenno ,

Impossible with modern reactors, technologyimproved a lot since then.

Captain_Baka ,

You mean the modern reactors who are still not in a commercial productive state? But even if these would be NOW ready to actually be available it's still so that there are a vast overwhelming majority of the old reactors which are not as safe as the meme was insinuating.

elfahor ,

All of those were caused by human mistake. But this does not mean that they must be discarded. Because human mistake happens. If it is with a solar panel, it's inconsequential. Not with a nuclear reactor. So yes, it is an issue to consider, but in truth all it means is that we have to be VERY careful

RippleEffect ,

I work with people.
Human mistakes are inevitable

Captain_Baka ,

If it is so that a human mistake can cause a big number of casualties and massive environmental damage it is far from safe, even if you are very careful.

Godnroc ,

Comparatively speaking, it's safer than coal mining.

Mining Accidents

Diplomjodler3 ,

This is just so fucking dumb. Yeah coal sucks. We should get rid of coal as quickly as possible. But saying nuclear is safer than coal while ignoring all other forms of energy that are orders of magnitude safer is as disingenuous as it gets.

winterayars ,

Nuclear power is actually safer than almost everything, period. Even with the major accidents. Yes, even renewables and other "green" energy.

See this comment's chart, for example: https://lemmy.ml/comment/11910773

Captain_Baka ,

200 years vs. 70 years. IDK if this is comparable. Also it is so that with nuclear accidents theres a lot of additional environmental damage, not just the human casualties.

Not defending coal mining here, coal is no good energy source by all means.

EldritchFeminity ,

Coal is often radioactive when it comes out of the ground, and thanks to poor regulations, is often radioactive when it goes into the powerplant, leading to radioactive particles coming out of the smokestacks and landing anywhere downwind of the plants.

More people have died from radiation poisoning from coal than from all of the nuclear accidents combined. But, as you said, 200 years vs. 70 years. But, also, nuclear is much more heavily regulated than coal in this regard due to the severity of those accidents. The risk of a dangerous nuclear power plant is nowhere near as large as commonly believed. It doesn't take long to find longlasting environmental disasters due to fossil fuels, from oil spills to powerplant disasters. They're used so heavily that it's just so much more likely to occur and occur more often.

All this to say that fossil fuels suck all around and we should be looking at all forms of replacement for them, nuclear being just one option we should be pursuing alongside all the others.

grue ,

Still less radiation than coal plants release in normal operation.

Thorry84 , (edited )

Nuclear is by far the safest form of energy production. Even with the big accidents, the impact hasn't been that big.

Chernobyl was by far the biggest, but that was 40 years ago, in a poorly designed plant, with bad procedures and a chain of human errors. We've learned so much from that accident and that type of accident couldn't even have happened in the plants we had at the time in the west. Actually if the engineers that saw the issue could contact the control room right away, there would not have been any issue. In 1984 that was a problem, in 2024 not so much, we have more communication tools than ever.
The impact of Chernobyl was also terrible, but not as bad as feared back in the time. In contrast to the TV series, not a lot of people died in the accident. With 30 deaths directly and another 30 over time. Total impact on health is hard to say and we've obviously have had to do a lot to prevent a bigger impact, but the number is in the thousands for total people with health effects. Even the firefighters sent in to fix stuff didn't die, with most of them living full lives with no health effects. And what people might not know, the Chernobyl plant has had a lot of people working there and producing power for decades after the disaster. It's far from the nuclear wasteland people imagine.

Fukushima was pretty bad, but the impact on human life and health has been pretty much nonexistent. The circumstances leading up to the disaster were also very unique. A huge earthquake followed by a big tsunami, combined with a design flaw in the backup power system, combined with human error. I still to this day don't understand how this lead to facilities being closed in Germany, where big earthquakes don't happen and there is hardly any coast let alone tsunamis. It's a knee jerk reaction that makes no sense. Studies have indicated the forced relocation of the people living near there has been a bigger impact on people's health than anything the power plant did.

Compare this to things we consider to be totally normal. Like driving a car, which kills more people in a week than ever had any negative impacts from nuclear power.

Or say solar is a far more safe form of power, even though yearly hundreds of people die because of accidents related to solar installations. Or for example hydroplants, where accidents can also cause a huge death toll and more accidents happen.

And this is even with the non valid comparison to the current forms of energy where we know it's a big issue. But because the alternative isn't perfect, we don't change over.
