Abstract

This paper discusses work to separate the first wall (FW) from the blanket so that the surface heat load coming from the plasma via radiation, convection, conduction and particle-wall interaction is separated from that caused by neutron deceleration. The tubular first wall (TFW), based on a water cooled steel structure, results in a slender configuration that is very effective to resist thermal loads. A thicker wall is allowed on the blanket plasma side and gives more flexibility in the case of danger. A thermohydraulic, electromagnetic and dynamic analysis confirms the viability of the proposed structure.
