Even with all the disasters included, nuclear power is safer than almost all other kinds (the exception being very large hydro plants), per unit energy.
Interesting. I know nuclear power is far safer than it's general reputation.
Is nuclear really safer than solar?
This[1] has some data and estimations for death rates measured based on deaths from accidents and air pollution per terawatt-hour (TWh), which suggests nuclear has 0.07 deaths per TWh, which is marginally higher than wind (0.04), hydro (0.02), and solar (0.02).
At the # of deaths produced by nuclear in normal operation, or by wind or solar, the "deaths" are dominated by the statistical lives due to the cost of energy itself.
The NRC uses a value of $9M for the value of a statistical life. That is, it is worth spending $9M if that will save one expected life.
Nuclear, solar and wind have deaths/energy somewhere in the ballpark of 1 life per 10^10 kWh. So, at $9M/life this cost is roughly $0.001/kWh. This is very small, which says that even minor differences in the cost of energy from various sources will be more important than the direct number of lives lost.
(This would not be true of fossil fuels, though.)
TLDR: it's more important to reduce the cost of energy from these non-fossil sources, and to choose the sources with lowest cost, than it is to make them safer. For nuclear, inherent safety could be useful if it would enable cost to be reduced, but not because nuclear needs to be safer.
That's bad data. Nuke is getting blamed for the Fukushima deaths that were due to the evacuation--neglecting the fact that the safest option was to stay put. If you replace the evacuation deaths (IIRC ~500) with the stay-put deaths (most likely zero) you about halve the nuke death rate.
The larger deployment of utility-scale solar does seem to have reduced it's death rate. (Many of the solar deaths are from falling off the roof during installation or maintenance. Utility-scale solar is normally on the ground and with better safety measures.)
> Nuke is getting blamed for the Fukushima deaths that were due to the evacuation
I think this is fair. /All/ deaths from nuclear and renewable power are due to accidents and bad decisions. Accidents and bad decisions aren't going to go away. It takes a monumentally boneheaded decision to make a nuclear power plant dangerous, but apparently the rate of monumentally boneheaded decisions is one per thirty years at our current level of nuclear power usage.

That rate is very likely to increase as time goes on and reactors become older and thus more prone to failure/some freak low probability incident happening.

So, it's very close!
