Burning of Minor Actinides and Fission Products from Spent Nuclear Fuel of Power Plants in Dual-Purpose Fusion Reactor

The paper presents the results of analysis of transmutation of Minor Actinides (MA) and Fission Products (FP) from the Spent Nuclear Fuel (SNF) of nuclear power plants. The transmutation scenario includes repeating periods of neutron irradiation in dual-purpose Fusion Power Reactor-Tokamak (FPRT) with Deuterium-Tritium plasma as neutron source and periods of Partitioning and Reprocessing (P&R) of fuel between the irradiation cycles. FPRT is intended for power production and SNF burning. The investigations are based on the results of an RF DEMO-S project with a fusion power of 2.5 GW and a modified blanket including fuel assemblies with minor actinides (Np, Am, Cm) and selected fission products (I-129, Tc-99, Cs-135, Zr-93, Pd-107, Sn-126). All obtained results are in conceptual stage and detailed engineering investigations will be required in case of the concept approval for imbedding in the total nuclear fuel cycle.
