摘要： 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.

摘要： 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.

摘要： Systems and methods for upgrading power output of previously-deployed nuclear power plants are described. Systems and methods may include a base nuclear power plant with a predetermined base power output rating and a predetermined base whole core refueling interval. Systems and methods may also include a power upgrade kit for increasing the base power output rating from the base power output rating to an increased power output rating without a change in fuel charge, reactor structures, or civil structures.

摘要： Provided herein is a small modular nuclear reactor plant that can comprise a reactor core comprising a primary sodium comprising cool primary sodium flow and heated primary sodium flow. Heated primary sodium flow can enter one or more IHXs where heated primary sodium exchanges heat with secondary sodium flowing through at least one intermediate sodium loop. Intermediate sodium loop can comprise secondary sodium flow that can transport heat to energy conversion portion via a heat exchanger. Energy conversion portion can comprise a bypass valve. Bypass valve can bypass an energy conversion working fluid (such as S-CO2) away from a turbine during periods of adjustment as discussed herein. The plant may comprise passive load following features along with the ability to provide cogeneration heat.

摘要翻译：描述了用于制造金属燃料的系统和方法。用于制造金属 - 燃料 - 基质金属陶瓷核燃料的方法可以包括通过底部浇铸或注射铸造与金属快速反应堆燃料结合的粉碎陶瓷颗粒，或粉末冶金方法。添加到金属燃料中的最大量的粉碎的陶瓷颗粒不得超过不能产生金属燃料的连续基质的颗粒。在短的照射时间之后，不管制造过程如何，燃料的微结构可以与没有粉碎的陶瓷颗粒的注射铸造燃料的显微组织基本相同。因此，广泛的现有的注射铸造燃料数据库，没有破碎的陶瓷颗粒，可能是预期辐射性能的一个很好的指标。每个过程可能有助于解决乏燃料问题，并可能在该过程中使Pu239变性。
