The foreseen future expansion of nuclear power would involve a solution to burn the long half-life transuranics (TRU) in the spent nuclear fuel discharged from LWRs. Moreover, high-energy neutrons can be very useful for many processes. The study addresses the development of a tokamak neutron source for a hybrid fission-fusion demonstration experimental device, using Ignitor-based technologies. Ignitor is a proposed compact high magnetic field tokamak, aimed at reaching ignition in DT plasmas. A revision of its operating parameters, in order to act a as a suitable neutron source in a hybrid device, is discussed, and a new operating scenario is proposed. Features of the tokamak neutron source are illustrated and preliminary results are discussed. A two-phase project is described, in order to test an Ignitor-based neutron source and then implement an experimental device for demonstration of technical feasibility of TRU transmutation.
