Abstract: A concept for a shaped first wall for ITER is presented. While keeping most features of the 2004 FDR wall (modules segmentation, plasma facing components technologies, plasma facing material), this concept provides protection of the lateral faces of the first wall panels against the intense parallel heat flux coming from the plasma. Excessive beryllium temperatures at the panel edges are avoided during regular operation. The intense heat flux at the top of the vessel is accounted for and protection is provided against the shine thru heat flux. Start-up and ramp down using the wall as a limiter is possible for up to 7.5MW, both inboard and outboard. This is rendered possible by the use of 5MW/m2 technology panels for 40% of the panels.

Highlights: [•] The ITER blanket is in the final stage of design completion. [•] Issues raised about the blanket heat loads and remote handling strategy are addressed, while integrating the in-vessel coils. [•] Key design justifications are presented, followed by a summary of the current status of the manufacturing plan and R&D activities. [Copyright &y& Elsevier]
