Natural iron isotopes influence on the neutron transport
Original language description
As an iron is the main structural component of nuclear power plants as well as future fusion power plants, the validation of neutron incident data libraries of iron is a must. Presented paper fits into ongoing validation activities and presents measuring neutron leakage spectra in the 0.1-1.0 MeV region from iron sphere of 100 cm in diameter by hydrogen proportional detectors. The experimental result is compared with ENDF/B-VII.1, JEFF-3.2 and CIELO nuclear data libraries. No library reasonably well describes whole region under study. Furthermore, elastic and inelastic XS sensitivity analysis for all iron isotopes was carried out. Fe-54 isotope elastic XS influence is comparable with Fe-56 XS influence up to 0.8 MeV. Fe-57 isotope elastic XS is significant in the region of 0.14-0.15 MeV. Additionally, there are large differences among libraries in both elastic and inelastic XS for Fe-57. Furthermore, it was found that Fe-58 isotope XS has negligible influence on the results. As a neutron source, Cf-252 with initial emission rate of 9.53E8 n/s was used in this experiment.
