Oversight of Safety Culture in Nuclear Installations

In this report, ENSI illustrates how it supervises safety culture. Based on a model for the over-sight of safety culture, it demonstrates that the supervisory authority cannot treat the entire content of safety culture in the same way. Part of this content can be observed and assessed with classical supervisory instruments, whereas other content – specifically, the values and world views of the members of the supervised organisation – is not accessible for oversight by means of the conventional instruments.
