| Abstract Scope |
Next generation nuclear reactors featuring high temperature liquids motivate the development of new sensors and characterization techniques that can withstand their extreme environmental conditions. For example, molten salt reactor licensing and predictive operation necessitates accurate thermochemical and thermophysical property values for salts of varying composition and temperatures. This objective has mobilized the research community to innovate new characterization methods under different conditions (e.g., offline vs. online). Among these methods, thermal conductivity measurements suffer several experimental challenges, which have limited their widespread adoption. A new online thermal conductivity sensor for high temperature liquids based on the thermoreflectance technique has been developed at NC State. The sensor’s operating principle, fiber optic design, and measurements applied to liquid metals will be presented. |
