Abstract: According to an aspect of the present disclosure, there is provided a nuclear reactor system which includes a core and containment structure. The interior of the containment structure is filled with both a liquid fuel and a gas. The reactor core is located inside the containment structure above the maximum resting level of the liquid fuel. In this condition, the core is filled by the gas, and a sustained fission chain reaction will not take place. A pump is provided draw the liquid fuel from the lower portion of the containment structure and circulates it through the reactor core, where the fuel reacts to produce heat. The reactor sustains a fission chain reaction only when the pump is on, and thus the reactor can be shut-down simply by turning off the pump, and allowing gravity to drain the core of the fuel salt.

Abstract: A nuclear reactor system is disclosed which provides an auxiliary cooling system and improved safety in the event of corrosion failure. The reactor comprises an inner reactor vessel containing a reactor core and a liquid fuel, and an outer containment vessel, with an intermediate space between the vessels being filled with a protective material. The protective material is at least partly in a solid state during normal operation of the reactor, and is liquefied by increasing temperatures within the reactor vessel due to abnormal operating conditions and provides enhanced cooling in the liquid state. The protective material and/or the coolant of a heat exchanger may dilute the liquid fuel during corrosive failure, and may optionally be provided with neutron absorbing material to prevent a fission chain reaction from occurring outside the reactor vessel.
