Another Cuban defector, geophysicist Tose Oro, observed that the complete absence of the sophisticated human and technological infrastructure needed to support a safe nuclear reactor program seriously compounded the risks inherent in the Soviet-Cuban scheme.
The optimist and competent decision makers at Petrobras did not plan to leave this reactor sitting at the port but since Rio de Janeiro highways do not support the weight of the equipment, well it is stuck there.
The NRC's last new reactor approval predates Three Mile Island, Chernobyl and Fukushima, all of which dented public support (and not just in America either: nuclear power supplies three-fourths of France's electricity, yet in one poll 57% of French respondents favoured abandoning it).
