==Learning from past disasters==
There have been two major nuclear meltdowns in history: Chernobyl and Fukushima.

Are all of today's nuclear reactors better made, to prevent the same things from happening again? {{rn}}

===Breeder reactors===

I'm not sure to what extent the same safety lessons apply when designing [[breeder reactors]] (an innovation that would be needed if nuclear power has any hope of really replacing fossil fuels).

===Land lost===
One factor in assessing nuclear power's environmental footprint: Consider how much land has been made uninhabitable from nuclear disasters.

If accidents keep happening at the same rate, here's how much of the Earth's surface we'd expect to lose, if (hypothetically) '''all''' the world's energy came from nuclear power:

Not sure if this is particularly helpful, since accidents are unforeseen and there's no reason to expect that the "rate" will stay the same. It could go up ''or'' down, considering all the advancement of nuclear tech that would be needed to scale up [[energy]] production.
