No, the argument is that it didn't "wipe the continent" and in fact caused far less damage than other things we're totally fine with. I don't see GP saying that they want an incident like this to repeat, just that, if it did, the consequences would be far less severe than "wiping the continent".
Why not exaggerate to the "entire planet" if we are going this way..
Regardless, in hindsight humanity could have prevented (at least to a significant extent) climate change if we doubled down on nuclear 40-50 years ago instead of stopping most expansion. What will be the cost of that?
I doubt so: 416 industrial nuclear reactors are deployed in the world today. They produce 10% of the electricity, itself 20% of the final energy, so nuclear power produces at best 2% of the energy consumed.
Nuclear power would provide 10% of the energy, which would be far from sufficient since it is necessary to electrify uses (in order to reduce the quantity of fossil fuel burned) and therefore produce more electricity, if we could multiply the power of the fleet by 5, therefore building around 1500 new reactors and keeping the existing fleet active. Hoping for this before 2100 would be absurd.
To extend this beyond that, we must hope for a revolutionary production process (pursued in vain for decades: breeders...), the ability to exploit less promising uranium deposits, thus tolerating increased emissions and costs, or the discovery of a large deposit.
Hoping for such a discovery is risky because intensive prospecting began at the end of the Second World War (the quest for nuclear weapons), and the rapid and sharp rise in the price of uranium (a bubble) that occurred around 2007 triggered a massive investment in prospecting, the results of which (15%) are very inadequate.
Therefore, multiplying the stock by five would leave at best 40 years of uranium certainly available under current conditions, and would therefore be an inept investment (one needs to amortize the plant).
Moreover there are geostrategic considerations: many nations don't have any reserve not want to have to buy uranium (creating a dependency) or technical expertise.
Since the 70s, oil reserves only lasted for another decade.
"Current reserves" is a moving target: once scarcity raises prices, prospecting makes sense again. Uranium is incredibly cheap. Prospecting is not worth it as there are enough reserves to exploit in the foreseeable future.
Seawater extraction is starting to be competitive with mining. With that, even natural Uranium becomes essentially unlimited.
In addition, we currently throw away >95% of the energy potential of the Uranium we use. Why? Recycling is not economically viable, because raw Uranium is far too cheap (see above). So facto 20 of what we've used so far is just sitting in Castors. And fortunately not in deep geological repositories, out of reach.
And then there's Thorium, which is significantly more abundant in the crust than raw Uranium. And of the Uranium, only a small percentage is currently usable.
> Uranium is incredibly cheap. Prospecting is not worth it as there are enough reserves to exploit in the foreseeable future.
A huge uranium bubble between 2004 and 2008, which triggered massive investments for prospection... and a ridiculous result (15%). The cause is known: the quest for atomic weapons triggered during the 1950's and 1960's massive prospection, and there is no decisive way to better prospect and few not yet prospected zones.
> Seawater extraction is starting to be competitive with mining
This is periodically announced since the 1970's, and no-one could industrialize.
Bottomline: "pumping the seawater to extract this uranium would need more energy than what could be produced with the recuperated uranium"

It would be sound if a ready-for-deployment model of industrial breeder reactor. There is none.
Having a massive head start at stopping or slowing down climate change would have been quite nice, though. Even if it weren't a permanent solution.
But yes, I agree that fossil fuels also had a lot of very significant political, economical and technological advantages over both nuclear and renewables which is why coal/gas/oil won. For renewables it might be changing now it just might be a bit too late...
No, those are your words. The dumbed down, skewed, ragebaity, Fox News level strawman. The guaranteed way to drag down the conversation when you have nothing of value to say: pretend the other guy said something just as worthless and then fight that because it’s easier and you think you have a shot.
Your arguments have been shot down all over this thread. Do you need a win so bad?
That it hasn't happened yet doesn't mean that it couldn't happen in the future. We have never had a worst case event but we do know pretty well what the consequences of a worst case event could be.
The worst case consequences of Chernobyl were stopped because people literally risked their lives to prevent it. The fire was put out, the steam explosion was prevented, and countless lives were saved as a result.
Even so, many countries spent billions, over several decades, to minimize the consequences. As far as 2000 miles away, animals are still to this day fed special foods and managed to avoid prolonged grazing in contaminated areas.
Think about it for a second - over 2000 miles away, almost 40 years later, this still requires active management. Despite best efforts to handle the situation when it happened.
Now consider that every reactor carries it's own copy of the risks, and they only generate around 10 TWh of electricity per year.
That's just way too little electricity for such a risk. It makes no sense.
Meanwhile solar and storage is deployed at a rate equivalent to a new reactor every month as we speak. Faster, cheaper, and comparatively risk-free.
Maybe. Maybe not. Nobody knows for sure, however after each of these click/bang the "there will be no more problem!" thesis seems less and less prominently published.
