Desalination technology is of utmost importance for combating water scarcity, as it allows humans to tap the limitless water of the ocean. Nuclear desalination is a subset of thermal-based desalination technologies and is promising in its ability to utilize nuclear waste heat (i.e. low-grade heat that is to be wasted in modern power-generation and industrial processes). DCSEC (Direct contact spray-assisted evaporation and condensation) is a powerful thermal desalination technology that uses high-pressure spray nozzles to make flash-boiling more efficient. A SCWR (Supercritical water reactor) is a generation-3 high-efficiency reactor that produces waste steam. A mathematical model is constructed of a system combining the two, and variables such as energy allocation, waste-steam temperature, and physical variables concerning the DCSEC system will be considered. Three outputs: water production, electricity production, and thermal efficiency will be measured. This system is expected to outcompete current nuclear desalination technologies.
