I don't doubt that that resulting number is still very low, or there (being intentionally optimistic about politics and society here) wouldn't be any nuclear plants.
Especially long-term storage is tricky, and if you need to consider time horizons of millenia, even small risks add up.

In fairness, you then also have to consider "regular" industrial accidents at nuclear plants, which are probably still much lower (due to the presumably much higher energy output per employee hour than other forms). But that's besides the larger point of low probability and historical risk.
The difference between renewables and nuclear power is who gets harmed.
When dealing with nuclear accidents entire populations are forced into life changing evacuations, if all goes well.
For renewables the only harm that comes are for the people who has chosen to work in the industry. And the workplace hazards are the same as any other industry working with heavy things and electric equipment.
