To study the thermophysical and neutronic properties of thorium-plutonium fuel, a conceptual design ofa hybrid facility consisting of a subcritical ThePu reactor core and a source of additional D-D neutronsthat places on the axis of the core is proposed. The source of such neutrons is a column of hightemperature plasma held in a long magnetic trap for D-D fusionreactions. This article presents computer simulation results of generation of thermonuclear neutrons in the plasma, facility neutronicproperties and the evolution of a fuel nuclide composition in the reactor core. Simulations were performed for an axis-symmetric radially profiled reactor core consisting of zones with various nuclear fuelcomposition. Such reactor core containing a continuously operating stationary D-D neutron source with ayield intensity of Y ¼ 2 1016 neutrons per second can operate as a nuclear hybrid system at its effectivecoefficient of neutron multiplication 0.95e0.99. Options are proposed for optimizing plasma parametersto increase the neutron yield in order to compensate the effective multiplication factor decreasing andplant power in a long operating cycle (3000-day duration). The obtained simulation results demonstratethe possibility of organizing the stable operation of the proposed hybrid ‘fusionefission’ facility. ⓒ 2020 Korean Nuclear Society, Published by Elsevier Korea LLC.
