The Safety and Environmental Work Package (WPSAE) has the scope to progress the safety studies for the future EU DEMO reactor, in the frame of the Eurofusion programme. A Generic Site Safety Report (GSSR) has been designed to include all the steps necessary to cover the safety issues of the nuclear fusion plant, from the definition of principles and requirements, through the detection of the source terms at risk, selecting the postulated initiating events, analyzing the accidents, quantifying the doses to the population and investigating waste production and its management. Eleven GSSR volumes collate the studies performed. The final goal is to prepare safety documentation, as complete as possible, to initiate a preliminary safety report when the plant site is selected. In parallel, the safety studies are supporting the design of DEMO, providing a feedback on the technical choices for the machine, the selection of materials, the use of space, the equipment necessary to correctly manage the safety risks by means of a continuous collaboration with the design teams of other DEMO WPs. The main achievements of the pre-conceptual phase of the DEMO program FP8 are presented in this paper, by summarizing the contents of GSSR volumes. Completion of the work is foreseen during FP9.
