The objective of this research is to know if there are distances between the expectations of the stakeholders and the information disclosed by the firm on the nuclear risk in its annual report. I wonder about the motives which lead companies to disclose environmental information, by associating the theories of the legitimacy and the stakeholders. I notice then the report which the financial accounting does not allow to report the whole nuclear risk. In particular, accounting does not integrate the risks of uncertain occurrence with important possible damages. Consequently, this research widens the field of analysis to contain all the information disclosed by the firm in its annual report. I determine the expectations of the stakeholders in information on the nuclear risk and confront them with the information disclosed by the firms in their annual report. Only 7% of the disclosed information about the nuclear risk in annual reports is quantitative visible information for the reader and dealing with precise objectives or with concrete programs led by the firms. A lot of information is not disclosed: the expectations of the regulating, financial and media stakeholders seem satisfied but those of the stakeholders of the environmental lobby groups would not be.
