Abstract

Abstract

Based on the theory of neutron release from the secondary neutron source, the calculation method for the neutron source strength was built. MCNP was used to calculate the reaction rate and neutron flux in the secondary neutron source assembly, and the average radioactive capture cross section of 123 Sb and the transform coefficient from radioactive activity to neutron source strength were obtained.
