> We could grind nuclear waste from current nuclear plants into fine powder and intentionally blow it into the atmosphere and still cause fewer deaths than coal, as well as cause the release of less radioactive material, as the coal industry causes huge amounts of uranium dust to be released in the air.

How does the math work on this? It seems... hyperbolic.

This is actually comparison with coal plants.

Coal contains traces of uranium, which gets released during burning. The uranium released in such way would have been sufficient to generate the energy obtained from burning coal if it used for fission instead [0].

So indeed, now we disperse the nuclear fuel in the atmosphere and freaking out about it much less then when instead it is being processed in a plant, and coal left alone.

Look up fly ash. Orders of magnitude more fly ash is produced than waste from nuclear plants, and it contains high concentrations of uranium and thorium.

While plants in e.g the US now captures most of it, huge quantities are still released into the air especially in countries with lower environmental standards.

But even places where it doesn't get released that just means having to deal with far more radioactive waste than nuclear plants produces.

It's not.

Naturally occurring radioactivity in coal ash means that coal burning power plants release far more radioactivity into our environment than nuclear plants do. In fact, if you want to get the least amount of radioactivity into your body, the safest place is behind the shielding of a nuke plant, because it would also protect you from naturally occuring radiation.

If you add up the total of radioactive elements in Bequerels released annually by coal plants and then assume 100% of all waste from power generating plants could be ground up and released and count that up, the amount of radioactivity from nuclear plants would still be less than coal.

We burn a LOT of coal, and despite the media's portrayal of how much a problem radioactive waste is, it's very overblown for power generating plants. Weapons production is another matter, but we've already been trying to stop that from happening for years.

There exists coal with more fissile energy, in the form of heavy isotopes such as thorium and uranium, than it has chemical energy, in the form of carbon-carbon bonds.

This is then burned in power plants, releasing the radioactive material into the atmosphere, and leaching it into groundwater from exposed piles of fly ash.

Yeah there’s a lot of rhetoric at play here. Very little in the realm of hard details.
