Parameters of the optimum alternative of a high-flux pulsed neutron source (fourth-generation neutron source in Dubna), which is foreseen to replace the IBR-2M reactor in the future, are considered. The source is based on a booster with a plutonium dioxide core (multiplication factor of no more than 0.98) and a tungsten target. The source is driven by a proton accelerator with an energy of 1.2 GeV and beam power 0.1 MW. The source power is 14 MW, and its pulse repetition rate is 30 1/s. The possibility of obtaining the average thermal neutron flux density on the surface of the flat water moderator up to 3 × 1014 n/(cm2 s) is demonstrated.
