Research Abstract

Evaluation methods for the delayed neutron yield (DNY) data for actinides for use in the analysis of dynamics of an accelerator-driven system were studied. The findings are the following: (1) The DNY calculated with summation method showed an exponential decrease similar to the one observed in experiments as we go to heavier actinides; (2) Two different sets of DN emission probability led to calculated results several times discrepant in magnitude; (3) More than 90% of contribution to the total DNY comes from major 20 precursors. This implies importance of improving accuracy of DN emission probability for these precursors; (4)At higher energies the DNY tends to decrease, the degree of which depends on prompt neutron multiplicity and proton even-odd effects of precursors.
