Due to the excellent collaboration of the fusion physics community and its coordination through the international thermonuclear experimental reactor (ITER) expert groups, it has been possible to establish a physics basis for a reactor class machine such as ITER. In addition, evolution in divertor physics has made a divertor design with acceptable lifetime and He removal rates possible. A disruption database based on improved input from many divertor tokamaks is instrumental for defining the design requirements in particular for the in-vessel components (blanket and divertor). During the last two years the design of all the major machine components was optimized for performance, assembly schedule, maintenance, safety and if possible cost reductions. A research and development programme focusing on 7 Large Projects which aim to manufacture and test full size or representative sized mockups of the major machine components and the RH tools is well under way. Preliminary results from this programme have influenced design solutions. A major evolution has occurred in the area of diagnostic integration. From the machine design point of view the diagnostic integration is performed in 4 major areas, namely the in-vessel sensors, the diagnostics in the divertor cassettes, the diagnostics in the equatorial ports and the diagnostics in the top ports.
