One thing I found out recently found out about nuclear that really shuts down home "great" it is as a fix for climate change is how limited fuel is for it.
Some numbers
Nuclear currently uses about 60,000 tonnes per year of uranium [1]
Nuclear is about 10% of electricity, 4% of energy as a whole [2]
There is about 8,000,000 tonnes of uranium reserves world wide [3]
For a 100% of current electricity demand by nuclear that's 13 years of fuel,
For 100% of energy (e.g. gas heaters replaced by electric powered by nuclear) that's 5 years of fuel.

Doesn't look so great when you do the math.
