In that episode the final Accident Investigation Board report said supervisors had “fostered a culture where employees do not feel comfortable raising safety issues to management.” Ernest Moniz, secretary of Energy from May 2013 to January 2017, said shortly before leaving that the day the drum exploded at WIPP was by far the worst day of his tenure. Los Alamos, he said in a subsequent interview with CPI, had “inadequate quality control in how they were packaging the wastes. There is no sugarcoating that.”
Moniz also said that during his tenure, there was “a clear pattern” in which the nuclear weapons laboratories were annually ranked more poorly by his department on their “operations” than on their other tasks, with Los Alamos “in particular…the lowest.” He said he had “no doubt they have had some management problems.”
