Couldn't you use the same reasoning for Chernobyl? A requirement to build an electric power plant, sloppy construction, sloppy operation, resulting in a catastrophic accident.
Exactly. Chernobyl was an unsafe design, when safe(r) designs were well known. Its operation was not just sloppy, the operation that was performed was a crazy experiment that was well beyond the operating specs of the reactor, clearly illegal and unsafe even in the best of times.
