It having an inconclusive effect on wildlife, but wildlife clearly being able to survive in the region, doesn't really detract from what I originally thought.
From the article you linked:
"No matter what the consequences of lingering radiation might be, there were massive benefits to people leaving."
100% renew
https://en.wikipedia.org/wiki/List_of_countries_by_renewable_electricity_production
All the countries that manage 100% renewable power use high levels of hydropower. Which is not an option for many countries and has it's own ecological problems associated with it.
Also, these 100% renewable countries have very little electricity requirements.
The United States produces at least produces four million Gigawatt hours of electricity per year. Compare that to some of these "100% renewable" countries.
They can never accidently summon centuries of nuclear winter.
Neither can nuclear power plants, lol. Nuclear power plants are not built in a way that can trigger a nuclear bomb explosion, which is inherent to the theory of nuclear winter of nuclear explosions leaving material in the atmosphere to blot out the sun.
Maintaining a fission reaction is an incredibly complicated process that requires human intervention to sustain. If nuclear plants fell into "disrepair" the would just turn off and be useless, like windmills.
with the incredible advancements in solar and wind it’s no longer the best option.
I haven't heard of any advancement that makes solar generate energy when the sun doesn't shine and wind generate energy when the wind isn't blowing.
they don’t poison the region.
Does this look poisoned to you?

You can't overproduce electricity. You have to match the load.
