Neutron multiplicity counting (NMC) is one of the most advanced Non-Destructive Assay (NDA) techniques. In this paper, the principle and method of generation of neutron pulse trains is studied. A model of 4π cube counter is established for 238Pu sample, the capture time of neutrons is gained by simulation code, then output the neutron pulse trains for post dispose from generated fissile initial-times. The result from post dispose of this neutron pulse trains show a small bias compared with input value, it’s an evidence for the validity of simulation in this paper.
