Actually in Venezuela every power plant ends in disaster but disasters in nuclear plants have much more severe consequences.
And hydro power they have today is not reliable. So they would need to use coal or natural gas. And both of these pollute compared to nuclear.
This is of course, ignoring the risks that the government claiming that they will take over the nuclear plant and put a high school dropout in charge.
What are you, a capitalist? That won't work in Venezuela's current political climate.
So for your solution to work the government would have to remove itself, and they want.
I'm a huge fan of nuclear power, but I do tend to think it would be a bad idea in an unstable country.
And take the risk of being "nationalized" by the state.
