Abstract.  The safe design of ITER has been paramount since the beginning of the ITER studies and the safety analysis was included in the Generic Site Safety Report produced in July 2001. On June, 28th 2005 it was decided to implement the experimental fusion facility in Europe, close to Marseilles, south of France. The design now needs to be checked according to the local legal requirements and the licensing will have to comply with the French regulations. The safety analysis will be presented to the regulator and public hearings should lead to the ``license”. Construction will then start. From March to May 2006 a public debate was launched to present the facility during a set of 20 meetings mostly in the locality. This process is the French implementation of the Aarhus convention, signed on June, 25th 1998. The future ITER operator was represented by the French Atomic Energy Authority (CEA), the ITER team being present for all meetings. The French regulations are mostly non-prescriptive and request that design provisions be taken according to the level of risk. Any codes and standards can be used as long as their safety margins are in good agreement with the level of reliability requested by the analysis. Nevertheless a few areas must follow prescriptive design rules. Fire prevention thus requires putting in place fire and confinement sectors; any chemical and radioactive vessels must be protected against accidental spilling. Pressure vessels and equipment must comply with a European directive and a French order in case of nuclear inventory. Building design and construction have to comply with European rules. The ITER designers, in close contact with the Participant Teams, are proceeding with the upgrading of the design to comply with these requirements. Priority has been given to those inputs which could have high impact on the design, for instance the building layout. The codes and standards for all equipment are also under revision in order to fit with the expected requirements, taking into account the procurement sharing agreement. Finally, and may be primarily, the QA system of the future organization will have to comply with a French order for nuclear facilities set in 1984 and close to the IAEA 50-C/SG-Q derived from the previous well known 50-C-QA. The responsibility of the future ITER operator for procurements dealing with safety is emphasized in this order.
