For one, even with disasters factored in, nuclear kills only 0.04 people per TWh of energy produced. Coal kills 160. That is four orders if magnitude more.
Oil fares better, but with 36 fatalities per TWh, that's still a thousand times more deadly than nuclear.

For two, every milligram of emissions from nuclear power is accounted for, as someone in the other thread said. All the waste fits inside a football field, and is stored in ginormous casks which can stand being smashed by a train, and are so thick you can hug them with no consequences to health and safety.
Meanwhile, emissions from coal and oil are vented to atmosphere. Including volatile radioactive trace contaminants. Which means that ironically, on top of the greater fatalities and the carbon emissions, fossil fuels have worse nuclear emissions.

As for storage, for one, that's hampered because the oblivious and the malicious get to contribute to the discussions. Fact is that there are sites for long term storage, which are in the process of being filled with spent fuel.
For two, much less of that stuff is needed if spent nuclear fuel is recycled. Which Japan and France do.

Finally, an electricity grid needs three things: capacity, stability and flexibility. Both nuclear and renewables offer stability, but only nuclear offers stability, while renewables offer flexibility.

The solution is not nuclear XOR renewables.

It is nuclear OR renewables.

Or nuclear AND renewables.
