Microfluidic Alpha Spectrometer for Materials Accountancy and Control in Liquid-Fueled Molten Salt Reactors
The University of Tennessee, Knoxville (UT) will develop a high-temperature, chemically resistant, diamond-based microfluidic alpha spectrometer (DiMAS) that will enable accurate online and/or at-line (the sample is removed and analyzed near the production process) measurement of alpha-emitting isotopes in LF-MSR fuel. The team will develop an optimal spectrometer design by using experimental and computational methods to evaluate the sensor architecture, packaging, and performance. The team also plans to develop on-site data processing algorithms that will provide rapid information via remote transmission to the end user as well as a commercial integration and maintenance strategy for LF-MSRs. UT’s DiMAS is expected to improve material control and accountability for LF-MSR fuel salts and reduce the cost of meeting regulatory requirements.
To accurately account for the fuel and transuranic composition within a liquid-fueled molten salt, UT will create a novel alpha spectrometer to measure the elemental and isotopic composition of the fuel.
