Study on the Man-Machine-Organization System Interfaces in Nuclear Facility Operation

Nuclear installations are complex socio-technical systems whose reliable operation is based on the success both of the technical equipment and of the human and organizational factors. In this paper a theoretical study of the interfaces in Man-Machine-Organization System (MMOS) was performed. So, in this phase the following were performed: • The identification of the characteristics of each element (man, machine, organization); • The identification and analysis of the man-machine interfaces (equipment); • The identification and analysis of the man-organization interfaces (communication, procedures, work process, training, time, work environment), so that for each interface was developed a circumstances module which can influence positive or negative the MMOS performance in accident conditions. • The identification and the analysis of the machine organization interfaces (maintenance plan, modification plan, management of aging, state of man-machine interfaces). So that for each interface was developed a circumstances module which can influence positive or negative the MMOS performance in accident conditions.
