The purpose of this investigation was to develop a design concept for a commercial tokamak hybrid reactor (CTHR) vacuum vessel/first wall system which satisfies the engineering requirements for a commercial environment. The hybrid reactor offers the unique condition that energy extraction from the first wall is not critical from the point of view of system economics. This allows the consideration of low temperature structural material for first wall application. Therefore, the CTHR aluminum vacuum vessel/first wall design philosophy was to utilize a low temperature design, thus minimizing the severe material and thermal stress problems associated with high temperature systems. The mechanical arrangement consists of a series of internally finned aluminum tubes fabricated into 30 sections and assembled around the torus. The coolant manifolds are at the top and bottom of the torus. The vessel sector length depends on the spacing between TF coils. Each sector is mounted on a rail system that permits translation for assembly or removal. The tubes in each sector are welded to tube sheets which are in turn welded to semi-cylindrical manifolds which distribute the coolant uniformly to the tubes.
