That is an opinion. The FACTS are these:
Before Fukushima it was not known what would it happen to a nuclear power station in the case of a huge natural disaster. Today we do know.
In fact, mother nature has performed a huge
destructive testing. Furthermore, this "test" carried out on a single nuclear reactor might have yielded non-binding results. However ten reactors under different conditions suffered the earthquake and tsunami. That's a big sample.
Today we know much more about the behavior of a nuclear power plant suffering a major natural disaster and therefore they are much safer than on March 10th.
