    Abstract: Nuclear reactor systems and methods are described having many unique features tailored to address the special conditions and needs of emerging markets. The fast neutron spectrum nuclear reactor system may include a reactor having a reactor tank. A reactor core may be located within the reactor tank. The reactor core may include a fuel column of metal or cermet fuel using liquid sodium as a heat transfer medium. A pump may circulate the liquid sodium through a heat exchanger. The system may include a balance of plant with no nuclear safety function. The reactor may be modular, and may produce approximately 100 MW e.

    Abstract: Systems and methods for fabricating metallic nuclear fuels are described. Methods may include preparing a metal feedstock charge; injection casting the metal feedstock charge into one or more molds to form one or more injection cast fuel slugs; determining one or more properties of the one or more injection cast fuel slugs; inserting one or more injection cast fuel slugs with acceptable properties into one or more jackets to form a plurality of fuel pins; and assembling a plurality of fuel pins into a multi-pin fuel assembly. The method may produce at least one multi-pin fuel assembly per day, wherein each of the at least one multi-pin fuel assemblies includes at least one hundred fuel pins.

    Abstract: Systems and methods for manufacturing metal fuel are described. Methods for fabricating a metal-fuel-matrix cermet nuclear fuel may include crushed ceramic particles combined with metallic fast reactor fuel via bottom pour casting or injection casting, or a powdered metallurgical process. A maximum quantity of crushed ceramic particles added to the metallic fuel must not exceed that which would fail to yield a continuous matrix of metal fuel. After a short irradiation period, the microstructure of the fuel may be substantially identical to that of injection cast fuel, without crushed ceramic particles, irrespective of the fabrication process. Thus, the extensive existing database for injection cast fuel, without crushed ceramic particles, may be an excellent indicator of expected irradiation performance. Each of the processes may contribute to a solution of the spent nuclear fuel problem and may denature Pu239 during the process.
