Slide № 21 Medin S.A. et al CONCLUSIONS The concept of power plant for fast ignition HIF involves a number of new components and devices. High power heavy ion driver and cylindrical target look to have clear basic design. The massive target causes some redistribution of energy fluxes resulting from microexplosion. Altogether the long driver train and target positioning in flight are problems of concern. The reactor chamber with wetted first wall has a minimum number of ports for beam injection. The composition of the reactor chamber of two sections makes easier the condensation problem and partly lessens pressure loading. The problems of coolant droplets and thermal stresses in blanket materials are of major concern in the reactor chamber. The energy conversion system consisting of three loops is a convenient object for the plant efficiency optimization and thermal equipment development.
