Influence of neutron energy on formation of radioisotopes during the irradiation of targets in reactor
Method of calculation of nuclear transformations in irradiated targets is realized for selection of optimal conditions for accumulation of radioisotopes in reactor, taking into account contributions of different energy neutrons (thermal, resonance and fast). Wide potentialities of program complex...

| description | Method of calculation of nuclear transformations in irradiated targets is realized for selection of optimal
conditions for accumulation of radioisotopes in reactor, taking into account contributions of different energy
neutrons (thermal, resonance and fast). Wide potentialities of program complex MCNP-4C based on the method of
statistical testing (Monte Carlo method) were used. Positive in proposed method is that all calculations starting from
spectra and fluxes of neutrons in reactor and completing by quantity of accumulating nuclei carry out within the
framework of the same methodological approach. It was shown by the example of radioactive 98Mo production in
Mo98Mo(n, γ)99Mo reaction that for achievement of maximal yield of target radionuclide. it is necessary to irradiate
start targets of Molybdenum in hard spectrum with essential contribution of resonance neutrons. |
