Effect of a Hybrid Fusion Plant Operating in a Fission and Fusion Reactor System on the Fuel Cycle

Abstract The paper discusses the prospects of an alternative way to close the fuel cycle, without recycling highly radioactive spent fuel. The essence is the potential production of the fissile isotope 233U from the isotope 232Th in a hybrid fusion reactor (HFR). The feasibility of using a hybrid fusion plant as a fuel accumulator in the nuclear fuel cycle, and the potential need of the system for hybrid fusion reactors necessary for its closing are estimated. A system in which two technologies, fission and fusion, working together, avoid the difficulties that arise as a result of the independent implementation of each of the technologies under consideration is simulated.
