Editorial: The government claims that the country’s nuclear power plants are entirely safe and hence that the public’s fear of nuclear accidents at these plants is groundless.
Conclusion
The public's fear (of nuclear power plants creating some safety concerns) is well founded.
Evidence
The government recently acted to limit the nuclear industry's financial liability in the case of a nuclear accident, so that in that even the nuclear industry wouldn't go bankrupt.
They say that unlimited liability would pose a threat only if injury claims can be sustained against the nuclear industry, and injury claims can only be sustained if there's a nuclear accident.
Evaluate
This is a tough paragraph to digest, but essentially the author is saying that the government's actions make it look like they think a nuclear accident is a real possibility. Even if it's just a remote possibility, the government is taking actions to limit the nuclear industry's liability so that it wouldn't go bankrupt in the event of a nuclear accident at a power plant.
Since the conclusion is just trying to establish "well founded public fear", we're just trying to strengthen the idea that .
Goal
We need an answer that sounds something like
the government is doing stuff to protect against → fear of X occurring certain ramifications of is well founded event X occurring
