Molybdenum-99 production via lead and bismuth moderators and milli-structure-<sup>98</sup>Mo samples by indirect production technique using Monte Carlo method

This study describes the design of a neutron activator that contains a beryllium target, a lead/bismuth moderator, graphite/PbF₂ reflectors, and a boron absorber. Production of ⁹⁹ Mo isotope using millimeter-sized ⁹⁸ Mo samples located in various regions of the activator under study was also simulated using the MCNPX-code. If the ⁹⁸Mo samples are placed in the reflector region, the yield increases due to a larger flux of epithermal neutrons.
