Our World in Data has recently looked at the safety of different energy sources and reached the same conclusion that Nextbigfuture has had for many years (since 2008). Nuclear energy is far safer than other major energy sources and is about as safe as wind and solar on a deaths per terawatt hour basis.
When Our World in Data looks at Chernobyl and Fukushima they give far more credence and consideration to the higher death estimates. Still even with those estimates nuclear energy is safer.
Nextbigfuture data from 2008.
