Multipurpose passive residual heat removal system for small fluoride-salt-cooled high-temperature reactor

A multipurpose passive residual heat removal system for a small fluoride-salt-cooled high-temperature reactor, comprising:

• a reactor body system, comprising:
• a cylindrical reactor vessel,
• a molten salt cold pool and a molten salt hot pool,
• a core,
• core axial reflectors positioned above and below the core,
• a core radial reflector positioned radially outside the core,
• a cold/hot pool coaming positioned radially outside of the core radial reflector and separating an interior of the reactor vessel into the molten salt cold pool and the molten salt hot pool,
• an axial flow pump,
• a FLiBe-FLiNaK primary heat exchanger, and a FLiBe-FLiNaK residual heat removal heat exchanger both provided in an upper portion of the reactor vessel with the primary heat exchanger positioned above the axial flow pump, and
• a control rod and drive mechanism;
• at a top of the core;
• wherein the multipurpose passive residual heat removal system comprises:
• a diverter valve comprising an inlet connected to an outlet of the FLiBe-FLiNaK residual heat removal heat exchanger,
• an air heat exchanger comprising a hot side inlet connected to a first outlet of the diverter valve,
• a confluence valve comprising a first inlet connected to a hot side outlet of the air heat exchanger,
• a heat storage tank comprising an inlet connected to a second outlet of the diverter valve and an outlet connected to a second inlet of the confluence valve,
• a thermoelectric power generation device;
• configured to receive heat from the heat storage tank and convert the heat into electrons, the thermoelectric power generation device connected in series with a DC combiner box and a DC/AC converter,
• a cooler configured to cool the thermoelectric power generation device,
• and an air cooling tower;
• having an inlet connected to an inlet of the air heat exchanger and an inlet of the cooler and an outlet connected to an outlet of the air heat exchanger and an outlet of the cooler.
