| Popis: | 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. |
