TECHNOLOGY LICENSING OPPORTUNITY New Heat Transfer System for Nuclear Reactors New heat transfer systems based on a novel design which increases safety and reduces cost. Opportunity: Idaho National Laboratory (INL), managed and operated by Battelle Energy Alliance, LLC (BEA), is offering the opportunity to enter into a license and/or collaborative research agreement to commercialize this new heat transfer system. Overview: Generation of power by nuclear fuel includes the generation of heat, such as by fission of nuclear fuel materials within a nuclear reactor core. Auxiliary cooling systems, which are also referred to as paths to “ultimate heat sinks”, are commonly utilized to safely remove heat from the nuclear reactor while in shutdown state. The vast majority of newly proposed nuclear reactors and reactor concepts are endowed with passive and/or inherent safety features at the cost of power level reduction and/or power density reduction and/or the addition of massive safety class structures holding large coolant inventories and hence a relative increase in the cost of installed power. The same reactors would benefit from an enhancement of their safety features and/or an increase in their rated power levels and/or power density levels. Without such an improvement, nuclear power solutions would remain expensive and potentially unattractive to private investors. Description: This technology is a heat transfer system for selectively removing heat from a nuclear reactor that utilizes a passive heat transfer mechanism when other heat removal paths and heat removal mechanisms are no long sufficient to cool the reactor. This system includes an inner wall surrounded by an outer wall with a volume in between that includes fins that facilitate the heat transfer between the two walls. The outer wall may be in contact with an external environment to conductively transfer heat from the outer wall to the external environment. It is structured to facilitate removal of heat at temperatures greater than a predetermined temperature based on the desired operating parameters of the reactor core, while not reducing efficiency by substantially removing heat from the reactor during normal use and operation. Benefits: Increases safe power generation capacity. Does not require active engineered systems Simplifies the design Reduces cost per unit installed power level Applications: Nuclear reactors Development Status: TRL 2. Concept stage, in need of testing and development. IP Status: US Patent Application No. 17/017,534, “Heat Transfer Systems for Nuclear Reactor Cores, and Related Systems,” BEA Docket No. BA-1057.
