The SOMBRERO fusion reactor, equipped with an IFE power plant powered by a 1000 MWe KrF laser, has 2677 MW of fusion power and 2891 MW of thermal power. The primary wall material of the SOMBRERO fusion reactor is a C/C composite and is 1 cm thick. SOMBRERO blanket consists of 3 zones with different 6Li enrichments. The first region consists of 3% C/C composite + 97% Li2O, the second region consists of 20% C/C composite + 80% Li2O and the third region consists of 50% C/C composite + 50% Li2O mixtures, and these three regions have thicknesses of 19, 40 and 40 cm, respectively. In this study, the effects of different fuel zone thicknesses of the SOlid Moving BREeder ReactOr (SOMBRERO) fusion reactor on neutronic performance were investigated. Static neutronic transport calculations were made with the Monte Carlo method. Neutronic calculations were performed for three different thicknesses, 6, 12, 19 cm, in the fuel zone using UO2 nuclear fuel. Increasing the fuel zone thickness without any change in the fuel ratio increased both the tritium breeding ratio (TBR) and the energy multiplication factor (M). As a result, at 6 cm fuel zone thickness, the tritium production rate and energy multiplication factor were calculated as 1.44 and 1.29, respectively, while at 19 cm fuel zone thickness, the tritium production rate and energy multiplication factor were calculated as 1.67 and 1.3, respectively.
