Abstract
The SOMBRERO inertial fusion reactor conceptual design study is of a 1000 MWe KrF laser driven near symmetric illumination system which utilizes a Li2O solid breeder moving bed in a blanket made entirely of low activation carbon/carbon composite material. The Li2O particles flow through the various parts of the blanket under gravity, then are transported through an intermediate heat exchanger and around the loop in a fluidized state by helium gas at 0.2 MPa. Liquid lead is used in the intermediate loop, going to a steam generator and a double reheat steam power cycle. There are 60 beams in the near symmetric illumination configuration. The laser energy is 3.4 MJ, the target gain 118 and the rep-rate 6.7 Hz. At the mid-plane, the blanket thickness is 1 m giving a tritium breeding ratio of 1.25 and an overall energy multiplication of 1.08. The first wall is at 6.5 m radius and is protected from x-rays and ions by 0.5 torr of Xe gas. Grazing incidence metallic mirrors are located at a distance of 30 ...
