This MOOC (Massive Open Online Course) is conceived as a first contact with the safety culture in all areas to continue, then, deepening in more specific concepts in the nuclear field. In order to establish a good safety culture and nuclear safety culture, aligned leadership is necessary. All these aspects will be worked in a dynamic, different and participative way, in which collaborative learning will be a key aspect. The goal of the MOOC is to ensure that students, industry workers and any person interested, know and transmit the safety culture and its importance. At the end of the MOOC, the participants will be able to understand and explain the aspects related to human behaviour and its management to achieve a strong safety culture. These general concepts will be focused to the nuclear industry and its differentiating characteristics.
