The United States Nuclear Regulatory Commission (NRC) typically begins its narrative on the “lessons learned” from the Fukushima Daiichi nuclear catastrophe with Japan’s March 11, 2011accident. Not surprisingly, the agency has avoided addressing the most critical lesson recognized in the accident’s official investigative report by Japan’s National Diet. In their finding, the unfolding radiological catastrophe […]
