    Disentangling the O-16 cross section using light water and heavy water benchmark assemblies

  • Original language description

    Fast neutron leakage spectra from the light and heavy water sphere of 30 cm in diameter with neutron source in its centre were measured by a stilbene scintillation detector in the region of 1-10 MeV in the distance of 85 cm from the spheres surface. We use the light and heavy water to eliminate the effect of hydrogen. Cf-252 with the approximate emission rate of 5.5E8 n/s was used as a neutron source for all measurements involved and was placed in the centres of the spheres. The measured neutron spectra are compared with MCNP transport code calculations in ENDF/B-VII.0, ENDF/B-VIII.b4 and JENDL-4 nuclear data libraries. Experimental results for both cases follows similar trend. The best agreement is achieved with ENDF/B-VIII.b4 library in both cases. All libraries underestimate experimental measurement in the region of 3-4 MeV. Furthermore, JENDL-4 library overestimates experiment in the region of 4-6.5 MeV. In addition, we performed cross section sensitivity analysis for elastic, inelastic and (n,alpha) reaction in JENDL-4 and ENDF/B-VIII.b4 libraries since they have almost independent evaluations of O-16.
