On calculation of neutron age in graphite

Abstract

The authors have compared the results of calculation of fission neutron age by the experimental data of carbon neutronic characteristics in different manuals. The paper introduces solution algorithms for slowing-down neutrons age. The comparison of calculation results at fission neutron slowing-down to indium resonance energy by the group method showed good convergence with theoretical and experimental data.
