No, Fukushima proved them right.
Fukushima ended in no way like Tchernobyl did.
The Soviet power plan released radioactivity in the air, make an entire area inhabitable and killed a few dozen a people.
Fukushima did nothing of this, everything stayed inside the structure, no radioactivity went out.
As Fukushima had no recovery generators available (no fuel in them), it is a great proof that a totally out of control modern power plant is not deadly.
