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.

Australian politicians have been arguing about nuclear energy for decades, and with whats going on now, petty distracting squabbling while state governments are gutting public infrastructure

The most frustrating thing is the antinuclear party is obviously fine with nuclear power, and nuclear armaments, just look at the aukus submarines

labors cries about the dangers to our communities and the environment are obviously disingenuous, or they wouldnt be setting a green light for the billionaire robber barons to continue tearing oil and minerals out of the ground (they promise to restore the land for real-sies this time)

Anyway, a nuclear power plant runs a steam turbine and will never be more than what, 30% efficient?

But how do we produce enough batteries for renewable energy?

[–] [email protected] 2 points 9 months ago (12 children)

Pumped hydro? Or one of the many other non battery storage options, or just over production

Redox flow, sodium ion, iron air, etc.

There are some 600+ current chemical-based battery technologies out there.

Hell for me, once sodium is cracked, that shit is so abundant that production wouldn't have many bottlenecks to get started.

Huh. So those of us that have always advocated for a nuclear baseline with wind/solar topping off until we have adequate storage solutions are climate change deniers? That's new.

[–] [email protected] 1 points 9 months ago (8 children)

First, no, that's not what I said. If you're only going to be arguing in bad faith like that this will be the last time I engage with you.

Second, baseload power is in fact a myth. And it becomes even worse when you consider the fact that nuclear doesn't scale up and down in response to demand very well. In places with large amounts of rooftop solar and other distributed renewables, nuclear is especially bad, because you can't just tell everyone who has their own generation to stop doing that, but you also don't want to be generating more than is used.

Third, even if you did consider it necessary to have baseload "until we have adequate storage", the extremely long timelines it takes to get from today to using renewables in places that don't already have it, spending money designing and building nuclear would just delay the building of that storage, and it would still end up coming online too late.

I used to be a fan of nuclear. In 2010 I'd have said yeah, we should do it. But every time I've looked into it over the last 10 years especially, I've had to reckon with the simple fact that all the data tells us we shouldn't be building nuclear; it's just an inferior option to renewables.

Blah blah blah nobody wants to hear actual evidence and suggestions that solar and wind might be better. We're on a mission for Nuclear power damn the Fukushima refugees and who cares if we store the waste encased in concrete at the bottom of the ocean which we know will eventually leak into the food stream

Noo kyaa larr is the fyuuu charrr

We're not gonna make any of those targets. Make peace with that and prepare accordingly. Pick a shitty future. Mad Max at worst, Elysium at best.

AMOC collapse, Carbon Sinks failing. We're boned. Cooked. Soon to be roasted. If our Govt's ever react at all, it'll be far too little far too late by the time they do.

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

[–] [email protected] 6 points 9 months ago (8 children)

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.

As a friend once said "benzene is what anti-nuclear people think nuclear waste is."

[–] [email protected] 1 points 9 months ago* (last edited 9 months ago) (3 children)

I mean, spent fuel is actually quite lethal when not packaged, but you get something like 300-400MWh out of a kilo of fuel. And that's significantly more than I'll use in my lifetime.

I'd gladly keep a kilo of dry-casked spent fuel in my house. It'd make an excellent coffee table or something, if a bit hard to move. I would absolutely not put a lifetime supply of benzene anywhere near my house.

Edit: it would make a shitty coffee table. 1 kilo of uranium oxide is just under 100ml

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.

[–] [email protected] 1 points 9 months ago

This.

Also, tie together more countries' power grids to even out production and demand of renewables, and reduce the need for other backup sources.

For a fraction of the cost of nuclear, increase the storage capacity as well. We've had days where the price per MWh was negative in many hours, because of excess production.

The barriers to carbon free energy aren't technical, they're purely political.

[–] [email protected] 1 points 9 months ago

The Simpsons shows it's safe and efficient 😅

[–] [email protected] 1 points 9 months ago

No, it's not the best we have. Solar and wind are way safer, cost less and don't produce waste.

Sure, nuclear power is safe until it isn't. Fukushima and Chernobyl are examples of that. Nuclear plants in Ukraine were at risk during Russian attacks. Even if you have a modern plant, you don't really think that under capitalism there is an incentive to care properly for them in the long run. Corners will be cut.

Besides that they produce so much waste that has to be: a) being transported b) stored somewhere

Looking at the US railroad system and how it is pushed beyond it's capacity right now and seeing how nuclear waste sites are literally rotting and contaminating everything around them I'd say it's one of the least safe energies. Especially if you have clean alternatives that don't produce waste.

[–] [email protected] 1 points 9 months ago

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

[–] [email protected] 1 points 9 months ago (4 children)

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.

[–] [email protected] 1 points 9 months ago

Also you can separate fuel waste from useful part. So even less waste.

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.

[–] [email protected] 2 points 9 months ago (1 children)

Meanwhile in Georgia (USA) they completed a new nuclear power plant and they have to raise rates because it went 100% over its $14 billion budget.

[–] [email protected] 1 points 9 months ago

Like every other nuclear power plant ever built

[–] [email protected] 1 points 9 months ago (3 children)

The Spanish government is now petitioning its public for ideas on how to waste power.

[–] [email protected] 1 points 9 months ago

They should have public fridges that are left open to help cool the planet.

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.

[–] [email protected] 1 points 9 months ago

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
