Unless a coal power plant opens up nearby, my guess is that the changes will be negligible.

These leaks aren't bigger than regular scheduled releases of the same type of polluted water. Unless they are lying about the amount or the type of leak they had, then government regulation of what a safe release is, is different from these leaks in only one way, these weren't caused by someone pressing a button while under government monitoring, but happened accidentally.

There is a reason why nuclear power is less deadly then even wind and solar power, per kilowatt generated.

This plant has to get it's shit in order, obviously. But from the information released so far, there is not much to be concerned about yet.
