Publication number: 20230127207Abstract: A simple nuclear reactor in which most of the reflector material is outside of the reactor vessel is described. The reactor vessel is a cylinder that contains all of the fuel salt and a displacement component, which may be a reflector, in the upper section of the reactor vessel. Other than the displacement component, the reflector elements including a radial reflector and a bottom reflector are located outside the vessel. The salt flows around the outside surface of the displacement component through a downcomer heat exchange duct defined by the exterior of the displacement component and the interior surface of the reactor vessel. This design reduces the overall size of the reactor vessel for a given volume of salt relative to designs with internal radial or bottom reflectors.Type: ApplicationFiled: October 10, 2022Publication date: April 27, 2023Inventors: Ryan Abbott, Darryl Appelgate, Haley Barsa, Michael T. Blatnik, Karl Britsch, Anselmo T. Cisneros, JR., Brian C. Kelleher, Samuel S. Goodrich, Ramesh Rajasekaran, Daniel J. Walter, Kent E. Wardle, Matthew D. Wargon

Patent number: 11367536Abstract: Configurations of molten fuel salt reactors are described that allow for active cooling of the containment vessel of the reactor by the primary coolant. Furthermore, naturally circulating reactor configurations are described in which the reactor cores are substantially frustum-shaped so that the thermal center of the reactor core is below the outlet of the primary heat exchangers. Heat exchanger configurations are described in which welded components are distanced from the reactor core to reduce the damage caused by neutron flux from the reactor. Radial loop reactor configurations are also described.Type: GrantFiled: March 19, 2020Date of Patent: June 21, 2022Assignee: TerraPower, LLCInventors: Ryan Abbott, Anselmo T.
