The flow channel includes an outlet flow channel downstream of the central core and an inlet flow channel upstream from the central core. A primary heat exchanger (PHX) disposed outside the central core and between the outlet flow channel and the inlet flow channel. The MCFR also includes a decay heat heat exchanger (DHHX). At least a portion of the DHHX is disposed above the core geometric center, and a fuel salt is configured to circulate at least partially through the outlet flow channel, the DHHX, the PHX, the inlet flow channel, and the central core.

摘要： A nuclear reactor includes a passive reactivity control nuclear fuel device located in a nuclear reactor core. The passive reactivity control nuclear fuel device includes a multiple-walled fuel chamber having an outer wall chamber and an inner wall chamber contained within the outer wall chamber. The inner wall chamber is positioned within the outer wall chamber to hold nuclear fuel in a molten fuel state within a high neutron importance region. The inner wall chamber allows at least a portion of the nuclear fuel to move in a molten fuel state to a lower neutron importance region while the molten nuclear fuel remains within the inner wall chamber as the temperature of the nuclear fuel satisfies a negative reactivity feedback expansion temperature condition. A duct contains the multiple-walled fuel chamber and flows a heat conducting fluid through the duct and in thermal communication with the outer wall chamber.

摘要： Capillary liquid fuel elements, created by the method of confining a liquid fuel in horizontal capillary troughs, are employed to create the core of a nuclear reactor to generate useful heat energy. The reactor incorporates the inherent advantages of a liquid fuel reactor: high specific power, high fuel burnup, inherent safety, ease of control, and simple fuel preparation, processing, reprocessing, and handling. The reactor in addition, has advantages unavailable in other liquid fuel reactors: high breeding potential, low delayed neutron loss, low pumping power requirement, low fission material external holdup, direct fuel-coolant heat exchange capability, and low construction material cost.

摘要： Disclosed is a support structure consisting of several layers of prismatic graphite blocks arranged over each other. The layers are constructed as closed units without expansion gaps and the blocks of one layer are keyed together with the blocks of the adjacent layers. The upper layers are composed of a plurality of preferably hexagonal graphite blocks equipped with passages for the cooling gas, while the bottom layer is formed by a number of support structures, each consisting of several support segments fitted together preferably into a hexagonal cross section, with each support unit resting at its central section on a column head of a round column and carrying a limited number of the hexagonal graphite blocks and that cooling gas channels are provided at the locations of the bottom layer where three support units meet.

摘要： A reactor vessel contains a fluidized-bed region of particulate material including both a neutron-moderating and a fertile substance. A gas flow including fissile material passes through the vessel at a sufficient rate to fluidize the particulate material and at a sufficient density to support a thermal fission reaction within the fluidized-bed region. The high-temperature portion of a heat transfer system is located within the fluidized-bed region of the reactor vessel in direct contact with the fluidized particles. Heat released by fission is thereby transferred at an enhanced rate to a coolant circulating within the heat transfer system. Fission products are continuously removed from the gas flow and supplemental fissile material added during the reactor operation.
