As the part of basic development of the active neutron nondestructive measurement techniques with collaboration between JAEA and EC-JRC, A technical development of delayed spectrometry intended for determining ratio of fissile isotopes (e.g U, Pu, Pu) is being performed. For the purpose of design of neutron moderator for D-T neutron source used in DGS, simulations are performed using simplified model. We report the results and a concept of system based on them.
