A nuclear fission power plant generates about as much CO2 as wind turbines if you have a look at it's whole lifecycle. That's because just operation doesn't generate CO2. But nonetheless that power plant is made from materials like lots of concrete. It needs to be built, decommissioned, etc. You need to mine the uranium ore, ... All of that generates quite some CO2. So it's far off from being carbon neutral. And we already have alternatives that are in the same ballpark as a nuclear power plant with that. Just that the fission also generates this additional nuclear waste that is a nightmare to deal with. And SMRs are less efficient than big nuclear power plants. So they'll be considerably less "clean" than for example regenerative energy. I'd say they're definitely not amongst the cleanest energy sources we have today. That'd be something like a hydroelectric power. However, it's way better than oil or natural gas or coal. At least if comparing CO2 emissions.

For over a century, the standard way we’ve been disposing of hazardous materials that can’t be easily recycled is to permanently bury it. We’re doing it with thousands of tonnes of hazardous materials daily.

A nuclear power plant only generates about 3 cubic meters of hazardous nuclear waste per year.

At the typical sizes we’re currently building them, you need 50-100 solar or wind farms to match the electricity output of a single nuclear reactor.

When we eventually dispose of the solar panels from those farms we literally end up with more toxic waste in heavy metals like cadmium than the nuclear power plant produced.

No solution is perfect.

But contrary to the propaganda, nuclear is one of our cleanest options.

For over a century, the standard way we’ve been disposing of hazardous materials [...]

Until 1994, one standard way of disposing of radioactive waste was throwing it into the ocean. There are at least 90.000 containers that got dumped along the shores of the USA alone. (Source: https://de.wikipedia.org/wiki/Altlasten_in_den_Meeren#Atomm%C3%BCllverklappung )

I'd agree that "No solution is perfect" qualifies for the history of nuclear energy.

Yes that’s correct.

To be more clear, nuclear waste is only a small percentage of the hazardous waste we’ve been disposing of by permanently burying it.
