Explora o nuclear, coordena o dos tempos e dos espa os profissionais

This contribution considers risky organizations as the link between multiple professional spaces with different temporalities. Risking to see their reliability and their productivity otherwise reduced, the exploitation of the productive organizations has to interlock multiple professional spaces, activities and temporalities thanks to schedules and intervention files. But these documents can turn out to be inadequate. Hazards, the apprehension of risk and the professional activities′ length interfere with the schedules. Intervention files are not always enhanced enough because of segmented professional spaces and the individual difficulties to meet each others. Based on a comparative empirical study between two sites in the nuclear area, this contribution will show that the junction of time and space in risky organizations turns out more effective when a cooperation made by justifiable recognized individuals technically is appointed to the coordination by schedules and files of intervention. They centralize and redistribute in real-time the information while accepting the meetings. To a larger extent speaking, the reliability of these organizations increases when they are equipped with positions, with spaces or with adequate technologies thanks to a long process of innovation and learning.
