The invention relates to the technical field of
nuclear fusion reactor energy conversion, in particular to a multi-loop coupled fusion reactor energy conversion
system and a working method. The conversion
system comprises a fusion reactor heat extraction
system, a heat storage system and a
thermodynamic cycle system, the fusion reactor heat removal system comprises a fusion reactor, a heat storage
heat exchanger and a steam generator, an outlet of the fusion reactor is connected with inlets of the heat storage
heat exchanger and the steam generator, and outlets of the heat storage
heat exchanger and the steam generator are connected with an inlet of the fusion reactor; the heat storage system comprises a high-temperature fused salt
storage tank, a high-temperature fused salt pump, an electric heater, a fused salt steam generator and a low-temperature fused salt
storage tank; an outlet of the low-temperature fused salt
storage tank is connected to an inlet of the heat storage heat exchanger, an outlet of the heat storage heat exchanger is connected to an inlet of the high-temperature fused salt storage tank, and an outlet of the high-temperature fused salt storage tank is connected to an inlet of the electric heater. The quality of steam generated by the fused salt steam generator is consistent with that of steam generated by the steam generator during operation of the fusion reactor, and stable and efficient operation of a turboset is guaranteed.
