Patent number: 11488731Abstract: This disclosure describes various configurations and components of a molten fuel fast or thermal nuclear reactor for managing the operating temperature in the reactor core. The disclosure includes various configurations of direct reactor auxiliary cooling system (DRACS) heat exchangers and primary heat exchangers as well as descriptions of improved flow paths for nuclear fuel, primary coolant and DRACS coolant through the reactor components.Type: GrantFiled: October 26, 2020Date of Patent: November 1, 2022Assignee: TerraPower, LLCInventors: Ryan Abbott, Anselmo T. Cisneros, Jr., Daniel Flowers, Charles Gregory Freeman, Mark A. Havstad, Kevin Kramer, Jeffery F. Latkowski, Jon D. McWhirter, John R. Suyes, III

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. Cisneros, Jr., Daniel Flowers, Charles Gregory Freeman, Mark A. Havstad, Christopher J. Johns, Brian C. Kelleher, Kevin Kramer, Jeffery F. Latkowski, Jon D. McWhirter

Patent number: 10665356Abstract: Configurations of molten fuel salt reactors are described that utilize neutron-reflecting coolants or a combination of primary salt coolants and secondary neutron-reflecting coolants. Further configurations are described that circulate liquid neutron-reflecting material around an reactor core to control the neutronics of the reactor. Furthermore, configurations which use the circulating neutron-reflecting material to actively cool the containment vessel are also described.Type: GrantFiled: May 2, 2017Date of Patent: May 26, 2020Assignee: TerraPower, LLCInventors: Ryan Abbott, Brian C.

Publication number: 20050121009Abstract: A Homogeneous Charge Compression Ignition (HCCI) engine system includes an engine that produces exhaust gas. A vaporization means vaporizes fuel for the engine an air induction means provides air for the engine. An exhaust gas recirculation means recirculates the exhaust gas. A blending means blends the vaporized fuel, the exhaust gas, and the air. An induction means inducts the blended vaporized fuel, exhaust gas, and air into the engine. A control means controls the blending of the vaporized fuel, the exhaust gas, and the air and for controls the inducting the blended vaporized fuel, exhaust gas, and air into the engine.Type: ApplicationFiled: May 30, 2003Publication date: June 9, 2005Inventor: Daniel Flowers
