That is factually false information. There are solid arguments to be made against nuclear energy.

https://isreview.org/issue/77/case-against-nuclear-power/index.html

Even if you discard everything else, this section seems particularly relevant:

The long lead times for construction that invalidate nuclear power as a way of mitigating climate change was a point recognized in 2009 by the body whose mission is to promote the use of nuclear power, the International Atomic Energy Agency (IAEA). “Nuclear power is not a near-term solution to the challenge of climate change,” writes Sharon Squassoni in the IAEA bulletin. “The need to immediately and dramatically reduce carbon emissions calls for approaches that can be implemented more quickly than building nuclear reactors.”

Wealer from Berlin's Technical University, along with numerous other energy experts, sees takes a different view.

"The contribution of nuclear energy is viewed too optimistically," he said. "In reality, [power plant] construction times are too long and the costs too high to have a noticeable effect on climate change. It takes too long for nuclear energy to become available."

Mycle Schneider, author of the World Nuclear Industry Status Report, agrees.

"Nuclear power plants are about four times as expensive as wind or solar, and take five times as long to build," he said. "When you factor it all in, you're looking at 15-to-20 years of lead time for a new nuclear plant."

He pointed out that the world needed to get greenhouse gases under control within a decade. "And in the next 10 years, nuclear power won't be able to make a significant contribution," added Schneider.

Long lead times against nuclear have bee raised for the last 25 years, if we had just got on with it we would have the capacity by now. Just cause the lead time is in years doesn't mean it isn't worth doing.

when is the best time to plant a tree? 30 years ago. When is the second best time? now.

[–] echodot@feddit.uk 19 points 1 year ago* (last edited 1 year ago) (1 children)

Surely the second best time would have been 29 years ago

[–] davepleasebehave@lemmy.world 2 points 1 year ago

Don't fuck this up for me bro

[–] abraxas@lemmy.ml 7 points 1 year ago (1 children)

As others pointed out, to build that many nuclear power plants that quickly would require 10x-ing the world's construction capacity.

My counterpoint is that if we had "just got on with it" for solar, wind, and battery, we would have the capacity by now and the cost per kwh of that capacity would be approximately half as much as the same in nuclear. And we would have amortized the costs.

No it wouldn't. China laid more concrete in 5 years than the entire world did in 100 years. I highly doubt that converting the entire world to nuclear is going to use that much more concrete. I mean hell, they laid like 15 or 20,000 miles of high speed rail in just a few years. They built like 300 million apartment units.

Long lead times, cost overruns, producing power at a higher price point than renewables, long run time needed to break even, even longer dismantling times and a still unsolved waste problem. Compared to renewables that we can build right now.

[–] Resonosity@lemmy.ca 1 points 1 year ago (3 children)

Did you read the quote? 15-20 years, as in decades before 1 nuke plant is built. I agree in that politicians of the past should have led us to a more sustainable and resilient energy future, but we're here now.

Advanced nuclear should still be 100% pursued to try to get those lead times down and to incorporate things like waste recycling, modularity, etc., but the lead time in decades absolutely means nuclear power might not be something worth doing.

The IPCC puts the next 10-20 years as the most important and perilous for getting a hold on climate change. If we wait for that long by not rolling out emission-free power sources, transit modes, or even carbon-free concrete, etc., then we might cross planetary boundaries that we can't come back from.

Nuclear is a safe bet and bet worth pursuing. I would argue that, along with that source from the IAEA, old nuclear is note worth it.

https://en.m.wikipedia.org/wiki/Kashiwazaki-Kariwa_Nuclear_Power_Plant

the largest fission plant was literally working 5 years after construction started

fission plants are just more expensive now because we don't make enough of them.

I guess safety standards changed but even wind power kills more people per watt than fission so ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

Nuclear could've easily worked if people didn't go full nimby in the past few decades

There are solid arguments to be made against both nuclear and renewables (intermittence, impact of electricity storage, amount of raw material, surface area). We can't wait for perfect solutions, we have to work out compromises right now, and it seems nuclear + renewable is the most solid compromise we have for the 2050 target. See this high quality report by the public French electricity transportation company (independent of the energy producers) that studies various scenarios including 100% renewable and mixes of nuclear, renewables, hydrogen and biogas. https://assets.rte-france.com/prod/public/2022-01/Energy%20pathways%202050_Key%20results.pdf

Those aren't arguments against nuclear power; those are arguments against the incompetence of entities like Southern Company and Westinghouse, as well as the Public Service Commission that fails to impose the burden of cost overruns on the shareholders where they belong.

I should know; I'm a Georgia Power ratepayer who's on the hook paying for the fuck-ups and cost overruns of Plant Vogtle 3 and 4.

It would've been way better if they'd been built back in the '70s, since all indications are that the folks who built units 1 and 2 actually had a fucking clue what they were doing!

[–] Carighan@lemmy.world 4 points 1 year ago

That is true, building a nuclear power plant doesn't help. The problem is how many we closed down in a panic, in particular after Fukushima. We could make great strides towards cleaner energy and cutting the actually problematic power plants (coal, gas) out of the picture as we slowly transition to renewables-only if we had more nuclear power available.

Of course, in hindsight it's difficult to say how one could have predicted this. There's good reasons against nuclear energy, it just so happens that in the big picture it's just about the second-best options. And we cut that out first, instead of the worse ones.

[–] red@sopuli.xyz 3 points 1 year ago

Your arguments didn't actually invalidate the comment you replied to. They are just arguments against nuclear being a short-term solution.

We need both, short and long term ones. Wind and water cannot be solely relies upon. Build both types.
