do not let "perfect" be the enemy of "good enough"

edit: quick addendum, I really cannot stress this enough, everyone who says nuclear is an imperfect solution and just kicks the can down the road -- yes, it does, it kicks it a couple thousand years away as opposed to within the next hundred years. We can use all that time to perfect solar and wind, but unless we get really lucky and get everyone on board with solar and wind right now, the next best thing we can hope for is more time.

I completely agree with everything you said except for ONE little thing:

You are grossly misrepresenting how far that can is kicked down, for the worse. It doesn't kick it down a couple thousand years, it kicks it down for if DOZENS of millennia assuming we stay at the current energy capacity. Even if we doubled or tripled it, it would still be dozens of millennia. First we could use the uranium, then when that is gone, we could use thorium and breed it with plutonium, which would last an incomprehensibly longer time than the uranium did. By that point, we could hopefully have figured out fusion and supplement that with renewable sources of energy.

The only issue that would stem from this would be having TOO much energy, which itself would create a new problem which is heat from electrical usage.

Then you just move the planet slightly further away from the sun! Problem solved!

[–] figaro@lemdro.id 9 points 1 year ago (1 children)

No man you gotta move the moon closer, since it's cold

I like the cut of your jib, sir.

The U235 is good for about 3 years, and pinning everything on something that has never had more than a half proof of concept is a bad choice.

[–] PersnickityPenguin@lemm.ee 2 points 1 year ago

As if breeder reactors don't exist

[–] HawlSera@lemm.ee 7 points 1 year ago

Some of the biggest blunders of all time come across because too many people let perfect be the Nemesis of good

[–] diyrebel@lemmy.dbzer0.com 6 points 1 year ago (1 children)

I really cannot stand that phrase because it’s commonly used as poor rationale for not favoring a superior approach. Both sides of the debate are pushing for what they consider optimum, not “perfection”.

In the case at hand, I’m on the pro-nuclear side of this. But I would hope I could make a better argument than to claim my opponent is advocating an “impossible perfection”.

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

But that is exactly what's happening. People are pretending like the alternative to investing in nuclear is living off 100% renewables from tomorrow.

[–] schroedingershat@lemmy.world 6 points 1 year ago (1 children)

Why is it supposed to be easier to get people onboard with nuclear (which is decreasing) than wind and solar (which are increasing at triple the rate of the nuclear construction peak in the 80s and growing at 20% p.a.)?

People are on board with VRE. Some of the are on board with nuclear too, but it's not working.

Nucleur isn't all it's cracked up to be, maybe it would be economical if we had heavily invested in the tech decades ago. But current plants have major issues, here is a snippet from another article:

The study also questions the reliability of the nuclear fleet, particularly given the dramatically low availability of French power plants this year – nearly half of the 56 nuclear reactors were closed even though the EU was in a complicated period of electricity supply with frequent peaks in the price of electricity above €3/kWh.

The availability of this electrical source is also questioned in view of the increasingly frequent droughts expected in the coming years, causing, in particular, low river flows and therefore associated problems of cooling power plants.

Study: Why investing in Nucleur is bad for the environment

Buying time isn't a great argument for nuclear when it takes so much longer than wind or solar to build a plant - median time of 88 months to build a nuclear plant compared to 8-14 for solar.

People will get on board when they see the cost per kwh.

[–] Saik0Shinigami@lemmy.saik0.com 3 points 1 year ago (2 children)

So best time to do it was 88 months ago... What the next best time to do it?

[–] WaxedWookie@lemmy.world 6 points 1 year ago (4 children)

Doing solar that's several times faster to build, cheaper per kwh, and doesn't require digging radioactive bullshit out of the ground seems like a better idea, no?

[–] PersnickityPenguin@lemm.ee 1 points 1 year ago

The answer is actually both. Highly developed nations have huge energy demands and they're probably going to need everything.

Nuclear is most of the time over budget and planning. That's a fact.

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

Over budget and over planning is bad.

...but also irrelevant - I gave the average real world delivery times.

[–] PersnickityPenguin@lemm.ee 1 points 1 year ago

Which isn't unusual for large construction projects. Nuclear is biggest cost problem is that each power plant is essentially a mega civil engineering project. They require cooling ponds, cooling towers, huge reactors, turbines, and radiation shields.

All of which are fairly large structures that have to be built to pretty high tolerances and have little room for construction defects which are very common in the industry. I work in construction and I can tell you that the majority of construction projects, whether they are an office building, a highway or a bridge run over budget.

There are always going to be factors outside of the control of the design team and the developer. Contractors may run out of labor, supply chains may have many years to complete some of the equipment and these issues compound the schedule which is already very complicated. Do we have an even discussed the expanded and politicized planning and safety rules and certifications that a new nuclear plant is going to need to follow.

I think the solution for micro reactors is pretty intriguing, except we need lots of power not small amounts of power. But a mass-produced reactor that rules off of an assembly line in a factory is likely to be on time and on budget because they can correct for for the problem of building things in the field. It's really hard for people to fabricate complicated machines when they're being rained on in the middle of winter during a storm.

But this is my argument against those who complain about Solar and Wind -- those won't kill you or destroy a location for hundreds of years if they break down and once they're installed they don't have to be fed by more mining, or anything else. Just wind and sun.

[–] jasondj@ttrpg.network 1 points 1 year ago* (last edited 1 year ago) (1 children)

Funny you say that. Solar and wind each have more human deaths per kWh than nuclear.

Worth mentioning that fossil fuels blow those numbers completely out of the water, though.

[–] Dr_pepper_spray@lemmy.world 1 points 1 year ago (1 children)

Where are you getting that from?

The death rate for nuclear was mostly from Fukushima, where about 2,300 elderly people died from the stress of moving from their homes. But their houses were also wiped out from a 35 ft tsunami so...

Chernobyl and Fukushima didn't directly kill very many people. Only 1 person died from radiation at Fukushima.

From the author:

"People often focus on the marginal differences at the bottom of the chart – between nuclear, solar, and wind. This comparison is misguided: the uncertainties around these values mean they are likely to overlap.

The key insight is that they are all much, much safer than fossil fuels.

Nuclear energy, for example, results in 99.9% fewer deaths than brown coal; 99.8% fewer than coal; 99.7% fewer than oil; and 97.6% fewer than gas. Wind and solar are just as safe."
