Accelerator driven subcritical systems (ADS) are one of the most viable methods for the transmutation and effective utilization of nuclear fuel. An important aspect of coupling the accelerator to a nuclear reactor is the generation of a high-energy neutron flux. The neutron flux can be generated by hitting a high-Z target composed of lead, tungsten, or other elements with a high-energy proton beam; To explore the control issues arising from coupling a proton accelerator to a subcritical reactor, an electron beam accelerator which produces a similar neutron flux can be used. The purpose of this study is to computationally predict the neutron production rate from a lead target that would couple an accelerator to a subcritical reactor assembly. MCNPX, a radiation transport code developed at the Los Alamos National Laboratory, was used in this study. The MCNPX predictions of photo-neutron production were compared with experimental results performed at Idaho Accelerator Centre (IAC), and showed good agreement.
