Abstract :
A three-dimensional neutronics calculation has been performed for the final optics of the laser driven reactor SIRIUS-P. The reactor utilizes grazing incidence metallic mirrors (GIMM) and dielectric coated final focusing (FE) mirrors placed at 25 and 40 m from the target, respectively. High aspect ratio neutron traps are attached to the outer reactor containment building. The GIMM can have a lifetime of 14 FPY assuming 80% recovery with annealing for a fluence limit of 1021 n/cm2. For a trap with an aspect ratio of 3, the flux at the FF mirror is reduced by about two orders of magnitude. The lifetime for the FF mirror will be 0.6 FPY for a fluence limit of 1018 n/cm2
