Safe, sure. Efficient? Not even close.

It's far, far more expensive than renewable energy. It also takes far, far longer to build a plant. Too long to meet 2030 targets even if you started building today. And in most western democracies you wouldn't even be able to get anything done by 2040 if you also add in political processes, consultation, and design of the plant.

There's a reason the current biggest proponents of nuclear energy are people and parties who previously were open climate change deniers. Deciding to go to nuclear will give fossil fuel companies maximum time to keep doing their thing. Companies which made their existence on the back of fossil fuels, like mining companies and plant operators also love it, because it doesn't require much of a change from their current business model.

The irony of Homer Simpson representing safe nuclear energy...

Hi, I work in waste handling, and I would like to tell you about dangerous materials and what we do with them.

There are whole hosts of chemicals that are extremely dangerous, but let's stick with just cyanide, which comes from coal coking, steel making, gold mining and a dozen chemical synthesis processes.

Just like nuclear waste, there is no solution for this. We can't make it go away, and unlike nuclear waste, it doesn't get less dangerous with time. So, why isn't anyone constantly bringing up cyanide waste when talking about gold or steel or Radiopharmaceuticals? Well, that's because we already have a solution, just not "forever".

Cyanide waste, and massive amounts of other hazardous materials, are simply stored in monitored facilities. Imagine a landfill wrapped in plastic and drainage, or a building or cellar with similar measures and someone just watches it. Forever. You can even do stuff like build a golfcourse on it, or malls, or whatever.

There are tens of thousands of these facilities worldwide, and nobody gives a solitary fuck about them. It's a system that works fine, but the second someone suggests we do the same with nuclear waste, which is actually less dangerous than a great many types of chemical waste, people freak out about it not lasting forever.

There are downsides to nuclear these days. Incredibly high cost with a massive delay before they're functioning. Solar + wind + pumped hydro + district heating is where it's at in 2024.

If you're interested in energy solutions and haven't read the RethinkX report on the feasibility of a 100% solar, wind and battery solution, it's definitely worth taking a look.

Whilst I agree that we need to decarbonise asap with whatever we can, any new nuclear that begins planning today is likely to be a stranded asset by the time it finishes construction. That money could be better spent leaning into a renewable solution in my view.

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

lol nuclear is really uneconommical, way too expensive and therefore really inefficient. You need 10-20 years to build a plant for energy 3 times more expensive than wind. For plants that still require mining. That produce waste we cannot store and still cannot reuse (except for one small test plant). For plants that no insurance company want to insure and energy companies dont like to build without huge government subsidies.

I know lemmy and reddit have a hard on for nuclear energy because people who dont know anything about it think its cool. But this post is ridiculous even for lemmy standards.

In Spain we are starting to get negative prices every weekend for electricity thanks to renewables. France is not even close to those prices with their bet for nuclear.

Don't get me wrong, I love nuclear power. And I'm not a big fan ok what thousands of windmills made to our landscapes. But efficiency wise renewable is unbeatable nowadays.

I'm pro nuke energy but to pretend there are no downsides is what got us into the climate mess we are in in the first place.

Cost, being a major drawback, space being another. And of course while they almost never fail, they do occasionally, and will again. And those failures are utterly catastrophic, and it'd hard to convince a community to welcome a nuclear plant, and if the community doesn't want it then it can't or shouldn't be forced onto them.

They also represent tactical strike sites in time of combat engagement. Big red X for a missile.

There are also significant environmental concerns, as we really have no good way to dispose of nuclear waste in a safe or efficient manner at this time.

It's likely that nuclear based energy is the future, but you need to discuss the bad with the good here or we are just going to end up at square one again. There are long term ramifications.

Just because it's safe doesn't mean it's the best we have right now.

• It's massively expensive to set up
• It's massively expensive to decommission at end of life
• Almost half of the fuel you need to run them comes from a country dangerously close to Russia. (This one is slightly less of a thing now that Russia has bogged itself down in Ukraine)
• It takes a long time to set up.
• It has an image problem.

A combination of solar, wind, wave, tidal, more traditional hydro and geothermal (most of the cost with this is digging the holes. We've got a lot of deep old mines that can be repurposed) can easily be built to over capacity and or alongside adequate storage is the best solution in the here and now.

Cost billions and have 10 year lead times?

Given that solar and wind are cheaper, get built to schedule and far less likely to have cost overruns, this meme is bullshit.

Sure, nukes are great. But we need clean energy right the fuck now. Spending money on new nukes is inefficient when it could be spent on solar and wind.

Renewables are better, cheaper and more scalable. Its not even close. Look at Denmark for how it can be done.

It's definitely not the best we have

stop shilling for industry, bootlicker

literally the least efficient in terms of cost and time.

battery backed renewables are a fraction of the price and are being deployed right now.

edit: the tech is cool as hell. go nuts on research reactors. nuclear medicine has saved my sisters life twice.... but i'm sorry, its just not a sane solution to the climate crisis.

Nuclear lobby really tries to sell us to the fact, that it's better to have control over power by a few big players. Must be terrifying to think about people creating their own power eventually.

Thats not even funny. It's not even a meme. It's just straight outright corporate propaganda. F off with that, Pinkerton!

I'm sure nuclear can be super safe and efficient. The science is legit.

The problem is, at some point something critical to the operation of that plant is going to break. Could be 10 years, could be 10 days. It's inevitable.

When that happens, the owner of that plant has to make a decision to either:

1. Shut down to make the necessary repairs and lose billions of dollars a minute.
2. Pretend like it's not that big of a deal. Stall. Get a second opinion. Fire/harass anyone who brings it up. Consider selling to make it someone else's problem. And finally, surprise pikachu face when something bad happens.

In our current society, I don't have to guess which option the owner is going to choose.

Additionally, we live in a golden age of deregulation and weaponized incompetence. If a disaster did happen, the response isn't going to be like Chernobyl where they evacuate us and quarantine the site for hundreds of years until its safe to return. It'll be like the response to the pandemic we all just lived through. Or the response to the water crisis in Flint Michigan. Or the train derailment in East Palestine.

Considering the fallout of previous disasters, I think it's fair to say that until we solve both of those problems, we should stay far away from nuclear power. We're just not ready for it.

I would rather see more investment on better renewable tech then relaying on biohazard.

You would be surprised to know the amount of scientific research with actual solutions that aren't applied cause goes against the fossil fuel companies and whatnot. Due to the fact that they have market monopoly.

ITT: ignorant people with 20+ years old knowledge.

Nuclear energy has been safe for a long time. Radioactive waste disposal is better than ever now.

Did we ever figure out toxic waste disposal?

Yes yes. Let's continute to use energy sources which are limited in terms of available but necessary resources and cause highly problematic by-products. It has been going on so well so far. Hasn't it?

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

Nothing about nuclear energy production is good, sensible and safe! You are dependent on a finite resource, you have to put in an incredible amount of effort to keep it running. Not to mention the damage caused by a malfunction (see Fukushima and Chernobyl).

Must. Not. Feed. The. Troll.

I agree it's safe but idk it's the best we currently have, I think that probably depends on locale.

Solar and wind (and maybe tidal?), with pumped hydro energy storage is probably cheaper, safer, and cleaner... But it requires access to a fair bit more water than a nuclear plant requires, at least initially.

But nuclear is still far better than using fossil fuels for baseline demand.
