*Abstract

Invention

The University of Florida is seeking companies interested in commercializing an innovative heat transfer fluid for nuclear reactors consisting of colloidal diamonds that will increase the critical heat flux level by 50 percent. Currently, more than 15 percent of the world’s electricity comes from nuclear energy, a statistic that is expected to rise as the world’s energy consumption continues to exponentially increase. This concern, coupled with a global reassessment of future reliance on fossil fuels, has caused an increase in nuclear energy development. Although research into nuclear energy has significantly increased, there are still many concerns that need to be addressed. One major problem in the feasibility of nuclear energy is the lack of an enhanced thermal transfer fluid that offers stability for pressurized water reactors. Thermal transfer fluids are needed that will raise the critical heat flux level so that critical fuel rod failures are avoided. Our researchers at The University of Florida have developed such a heat transfer fluid consisting of colloidal diamonds that will increase the critical heat flux level by 50 percent.

Application

Heat transfer fluid for increased heat flux levels

Advantages

• Increases critical heat flux level of pressurized water reactors, minimizing risk of fuel rod failure
• Improves thermal conductivity over water by 150 percent, increasing cooling system efficiency
• Enables a sustainable energy source with reduced carbon emissions, providing a major competitive advantage in a lucrative industry
• Eliminates reactor erosion, reducing maintenance costs

Technology

This heat transfer fluid, consisting of colloidal diamonds, will increase the critical heat flux level of pressurized water reactors by 50 percent. A pressurized water reactor is comprised of a core including fuel assemblies that contain fuel rods filled with fuel pellets thermally couples to a steam generator, a turbine, and a condenser coupled to a water based cooling system. The water based cooling system comprises a heat transfer fluid including a plurality of colloidal diamonds. The diamond particles which can be natural or synthetic, have a mean size of 1 nm to 2 microns. The concentration of diamond particles ranges from 0.0001 to 10 volume percent in the total heat transfer fluid.
