Well if by close to nothing he means waste lasting 300 years instead of 10,000 years and by latest generation he means gen IV reactors like bn-800, superpheonix, oklo, moltex etc sure he is basically correct. Here’s a source where you can read more about breeder reactors: (which is what he is referring to)
These aren't nuclear power plants. They're designs of nuclear power plants. None have been constructed (well, aside from old plants like Superphenix, which was a failure, so much so that the French have mothballed their fast reactor program.)
Moreover, they would be considerably more expensive than existing plants (especially if fuel is to be reprocessed), so they're nonstarters.
Ah yes. “Old” plants. This plant is “old” so we could never build more like it. What an argument. And no, they would not be “considerably more expensive” because we wouldnt build a fleet of them until uranium was expensive enough that they would be cheaper. Thats why most countries have put off breeder reactor development not because they were “failures” whatever that is supposed to mean.
"Old" as in "we built it and discovered it's not wanted". The French basically gave up on the idea of fast reactors (as did the Japanese, although their fast reactor program appears to have been an excuse to obtain a stockpile of separated plutonium in case they need to make bombs). There's no market for them. The Russians have continued to try, but they're selling LWRs.
The big problem with fission is that it's too expensive. Fast reactors make that main problem worse. There is no economic margin to do fancy (and expensive) things to try to address the lesser issue of nuclear waste.
In an economic sense, when compared to burner reactors, this is correct. As the rise of wind and solar has shown however, political will and popularity matter more than pure economics. Burner reactors are more of a 22nd century technology, assuming the grid storage problem doesn’t get solved by then and we just go full renewable on economics. But nothing is set in stone
What nonsense. What solar and wind have shown is the overwhelming importance of economics. They are dominating now because they have become cheap, not because of some sort of "triumph of the will". And they have become cheap because they are inherently the kind of technologies that has good experience curves. Unlike nuclear.
Nonsense? Why was US nuclear built at all in the 60’s and 70’s? Or in France? Because it was cheaper? No. It was built because people thought it was a good idea. The same is true for intermittents today. They are popular with a section of the population so they get the funding. And no, nuclear has fantastic experience curves. Look at any country building lots of reactors and the n-th of a kind is cheap. Building out nuclear and maintaining industry experience works to keep costs low.
1GW of nuclear is worth about 3 to 6GW of solar if you account for the weather and nighttime. If you also account for nuclear not needing fossil backup its worth even more
France decarbonized way before the rest of Europe with nuclear and it wasn't expensive. 50 reactors for $200 billion. Gernamy has spent twice that on intermittents and still relies on coal
Such a tired point. It’s not the 1970s anymore, and the west can build any large projects cheap. Go look at the projected costs for France’s new fleet, and that’s before the inevitable cost overruns
"EDF estimates EPR2 programme cost at EUR72.8 billion"
France's EDF has said its preliminary cost estimate for the project to build six EPR2 reactors at Penly, Gravelines and Bugey totals EUR72.8 billion (USD85.3 billion).
Each reactor outputs 1650 megawatts of electricity running at full power. Assuming they run at 92% capacity factor, that's $9.38 per real annualized watt.
Great. So 538TWh per year is 61 GW so roughly 61 GW * $9.38 = $576 billion staggered over the 80 year life of nuclear plants is $7.2 billion per year of capital expenditure.
For comparison, wind is about $5/W. Assuming a 35% capacity factor and a 30 year expected lifetime for the latest turbines that comes to $10.0 billion per year of capital expenditure with no storage or fossil backup systems or extra capacity given weather variability.
PV solar is between $.97 and $1.16 per watt, so that's going to be the front line. With storage you can get from $1.60 to $2. This is already the bulk of the power generation in Europe and is only going to increase. The idea that you're going to run nuclear plants at 95% capacity factor economically is also very suspect in a continent saturated with cheap PV solar.
US NREL Puts it at $2/W with no storage and ~20% capacity factor. Lifetime of latest panels is unknown but optimistically is 25 years. Assuming perfect and free storage that comes to $24.4 billion per year of capital expenditure for a country the size of France to be 100% solar. So no, it would not be more economical to use solar over nuclear. Wind would be better but when you add the full system costs of storage and backup intermittent heavy systems are vastly more expensive and emit more carbon than nuclear ones.

Intermittents are only gaining market share because their unreliable and intermittent power which is less valuable is being purchased by governments at prices that far exceed what it is worth. In other words, massive hidden subsidies. Without those, there would be next to no intermittents on the grid anywhere.
Uranium actually does not require mining. Most uranium is extracted using underground wells where water is pumped underground and the Uranium is extracted from the water. Also extracting Uranium from sea water (which would be basically unlimited) is close to being commercially viable and has received a lot of lab-scale research.
Also, Uranium is only recyclable once with light water reactors. With breeder reactors (which have been built in the past) it can be recycled a hundred times.
Russia is by far the most advanced. However, its "BN-800" reactor, which began operating in 2014, is so uninspiring that they abstain from deploying any of them, preferring the classic "VVER" (non-breeder) models, and its planned successor, named "BN-1200M," has been postponed to 2035.
This doesn't represent an abandonment of breeder reactors, as this nation is actively exploring another avenue: the "BREST" architecture (lead coolant rather than sodium), with a small demonstration reactor (300 MW) whose construction began in 2021, essentially "back to square one."
it depends where your electricity comes from actually. In west Virginia it comes from coal so is worse than a hybrid but still better than non-hybrid gas cars (in terms of CO2)
No it's not. The efficiency of an EV Motor > efficiency of ICEV motor. Even with 100% black coal. The carbon is reduced by about 30% IIRC (that number can and does improve as the grid greens).
Who cares? Those blades and that concrete are totally inert and just sit in the ground after their useful life. The ground already has lots of rocks in it.
Look up how long a dunkelflut is and do the math yourself.
There is a reason that Germany and Europe is planning to do very long distance transport of solar energy. Only by having diverse weather pattern across Europe can you possible do it. Of course this is also incredibly expensive.
Even if you assume a very low price from batteries like Form Energy, its still insanely expensive.
I was curious to see how this number was derived and unfortunately the 20.41 euro/MWh “reducing effect” figure has absolutely no explanation as to how it was calculated. Given that AEE is a wind industry lobbying organization I suspect this number is picked in a way that is maximally favorable to wind. I really wish they would tell us how this number was arrived at so I could make up my own mind as to how reasonable it is.

This. If western “liberal” “democracies” are concerned about children’s privacy then we should push back on surveillance capitalism, not force people to submit government id in order to express their opinion online.
