Nuclear is the most regulated one. Start requiring full recycling / disposal of solar or wind and how expensive do they get?
Comment on 40% of US electricity is now emissions-free
partial_accumen@lemmy.world 9 months agoNearly all of nuclear in the USA was built decades ago. Instead of being “paid off” and being cheaper, its still more expensive to generate electricity with nuclear than nearly all other electricity sources in the USA.

Nuclear is the most regulated: True. Accidents in nuclear have the most consequence, by far, of any generation source.
I would imagine that if we’re just going for disposal, solar and wind are still pretty cheap. With zero recycling wind turbine blades can just be buried after their 25 year life cycle. source.
Same landfill disposal option is available for solar panels at $1 to $5 per panel. source
This would be the level of disposal nuclear has, except low and high level nuclear waste is much more costly and potentially destructive even after disposal.

Burying it in the ground with no considerations for leachants is not what nuclear disposal is.

It’s not significantly more expensive though. en.wikipedia.org/…/Cost_of_electricity_by_source
And even if it was, it has other benefits.
Like using significantly less land, and being safer.
It can also work as a source of heat for district heating or various industrial processes, and since the plants themselves have no emissions, they can be reasonably placed in cities for this purpose without harming people. Using heat directly is more efficient than converting it to and from electricity.
Nuclear has it’s place.

I’m looking at that source it shows:
-nuclear $6,695-7,547 /kw -solar pv $1,327 /kw
At the most generous calculation that puts nuclear power at 5 x more expensive that solar PV. So if you have a theoretical pure electricity bill on solar PV of $100/month, your theoretical pure electricity bill on nuclear of $500/month.
I’m not sure how you reach the conclusion that nuclear is not significantly more expensive.

Here’s the summary for the wikipedia article you mentioned in your comment:
Different methods of electricity generation can incur a variety of different costs, which can be divided into three general categories: 1) wholesale costs, or all costs paid by utilities associated with acquiring and distributing electricity to consumers, 2) retail costs paid by consumers, and 3) external costs, or externalities, imposed on society. Wholesale costs include initial capital, operations & maintenance (O&M), transmission, and costs of decommissioning. Depending on the local regulatory environment, some or all wholesale costs may be passed through to consumers. These are costs per unit of energy, typically represented as dollars/megawatt hour (wholesale). The calculations also assist governments in making decisions regarding energy policy. On average the levelized cost of electricity from utility scale solar power and onshore wind power is less than from coal and gas-fired power stations,: TS-25 but this varies a lot depending on location.: 6–65

I’m not sure what you are referencing, but there are good reasons why nuclear power is expensive: lots of engineering and construction hours, strick safety and quality standards for design and materials, and no externalities, since decommissioning and waste handling have to be accounted and baked into the final utility cost to consumers. In other words, even if it’s difficult to pay off a nuclear power plant (in a liberalized energy market of course) it’s still money well spent. The same requirements and expectations should have to apply to other industries as well.

Are you arguing its a “good thing” for existing built plants or for propose plants yet to be built? I wasn’t sure, but the result is the same for both. Nuclear is too expensive for what it provides in the face of better alternatives. I’m happy to back my statements with sources. Which position were you arguing?
assassin_aragorn@lemmy.world 9 months ago
There is one thing that new nuclear reactor designs can provide that there is no good alternative for, and that’s consuming existing nuclear fuel. We can use breeder tractors to convert our existing waste into usable fuel for newer reactor types (I want to say Thorium but I’m not positive).
Our best outlook for the future is for us to build at least as much of these are necessary to clean up our nuclear waste.
partial_accumen@lemmy.world 8 months ago
Building reactors just to reprocess fuel would be a really bad way to solve that problem. If we are requiring reprocessing, there are other countries that run these that we could just ship our fuel to.
Breeder reactors bring some serious security problems
One of the really great things about civilian nuclear power in the USA is that the fuel or waste can never be built into a nuclear bomb. Our reactors run on Uranium-238. This is the most common isotope of uranium and its plenty fissile to reach criticality for power generation. Nuclear bombs use Uranium-235 or Plutonium-239.
The way a Breeder reactor can reprocess fuel is by turning “spent” Uranium-238 into, you guessed it, Plutonium-239. Plutonium-239 can be used to generate electricity in reactors too. So now you’ve got civilian power plants that are housing and handling weapons grade nuclear material. The security of the facility, supply chain, workers and everything suddenly has to go through the roof. All of those things increase the total costs to the resulting electricity. With nuclear already being more expensive than other cleaner and dirtier alternatives, running Breeder reactors makes that nuclear power yet more expensive again!
CrimeDad@lemmy.crimedad.work 9 months ago
My position is simply that it’s a good sign if nuclear power is more expensive than other types. We should be suspicious of anything that claims to offer a better deal.
partial_accumen@lemmy.world 9 months ago
What an unusual stance. You eluded to the externalities of other sources as your concern. For coal I would agree. However, for wind and solar the studies have shown those to be substantially cheaper even with externalities factored in.
What do you base your reasoning on that wind and solar are not factoring in externalities?
