The design calculations of the rectangular moderator, which were obtained through Monte Carlo simulation, have been verified experimentally through thermal neutron yield measurement using CR-39 nuclear track detectors (NTDs). Information about the spatial and energy distribution of neutrons in the volume of the lead target and the uranium blanket was obtained with sets of activation threshold detectors (Al, Y and Au) and solid state nuclear track detectors (SSNTD). 1 (marzo 1939- ).-- México: Universidad Nacional autónoma de México, IIS, 1939-v-.
