HCSB-DEMO concept design is carried out at SWIP. In order to handle power from a core plasma region, a super-X divertor is preliminarily designed and investigated for HCSB-DEMO. It increases the target surface area by expanding the magnetic flux surface with another X-point generated near the targets and increases the parallel connection length by moving the outer divertor target to larger.. and... The heat load at the targets is investigated by B2.5-Eirene. With heating power flowing into SOL/divertor regions being.. - 600MW, when the density at the separatrix is n(e) = 3.5 x 10(19) m(-3), the peak heat load at the inner and outer divertor is 9.2MW/m(2) and 3.7MW/m(2), respectively, which is much less than those of the standard divertor without impurity seeding, and also below the design targets (10MW/m(2)). Thus the super-X divertor may work well for HCSB-DEMO to solve the high heat load problem at the divertor target without impurity seeding from this preliminary concept design and simulation.
