Nuclear analysis for the inertially confined direct drive laser fusion power reactor SIRIUS-P

The SIRIUS-P commercial reactor design produces 1000 MWe and is driven by 60 KrF laser beams. The chamber has an inner radius of 6.5 m and consists of a first wall fabricated from a carbon/carbon composite and a blanket made of SiC. The chamber is cooled by a flowing granular bed of solid ceramic material, TiO2 for the first wall and Li2O for the blanket. The overall tritium breeding ratio is 1.09 and the overall energy multiplication is 1.08. Adequate shielding is provided around the chamber to reduce the operational dose to acceptable levels. Grazing incidence metallic mirrors are utilized to enhance the lifetime of the dielectric coated final focusing mirrors.
