Fast neutron (flow) response measurement with silicon carbide (SiC) is investigated in a typical fusion–fission hybrid reactor, using the most current Monte Carlo transport code (MCNPX2.7.0). Silicon carbide is used as the clad of the fissile fuel assemblies. The elastic scattering of ²⁸Si(n,p)²⁸A1, ²⁸Si(n,α)²⁵Mg, ¹²C(n,α)⁹Be, ¹²C(n,n′)3α, ²⁸Si(n, n′)²⁸Si, and ¹²C(n,n′)¹²C was calculated, and the results were validated using ENDF reaction cross sections. The results showed that the SiC layer of fuel assembly can be used as a detector for proton, alpha, and elastic scattering in fuel assemblies.
