The evidence used by the NRC to detect these nuclear safety culture problems included work force surveys indicating a sizeable portion of workers reluctant to raise safety concerns and allegations received by NRC from workers about reprisals and harassment they experienced after raising safety concerns.
Ample evidence strongly suggests that the NRC itself has nuclear safety culture problems. The NRC’s Office of the Inspector General (OIG) has surveyed the safety culture and climate within the NRC every three years for the past two decades. The latest survey was conducted during 2015 and released in March 2016. Figure 1 from the OIG’s 2015 survey along with data from the annual Federal Employee Viewpoint Surveys and other sources show safety culture problems as bad as—it not considerably worse—than the worst safety culture problems identified at Millstone, Davis-Besse, and yes, even the TVA reactors.
