High-Fidelity Flow Measurement Methods for Molten Salt Systems

This PhD project will develop a novel, high-resolution diagnostic tool based on the Wire Mesh Sensor (WMS) to measure phase fraction distribution and temperature distribution in reactor-relevant molten salt environments. Understanding flow behaviour in molten salts is critical to the development and safe operation of next-generation nuclear reactors, including fusion and molten-salt fission systems. Working across two state-of-the-art facilities, the molten salt loop at the University of Leeds and the SMALLAT testbed at UKAEA, the successful candidate will gain experience in sensor development, experimental fluid mechanics, and high-temperature instrumentation while generating benchmark data to validate advanced computational models used in reactor design and safety assessment. The project directly supports the UK's ambitions in both fusion and advanced fission by addressing a key knowledge gap that underpins the safe and efficient deployment of next-generation reactors. This is a 4-year fully funded PhD position as part of the Centre for Doctoral Training (CDT) in SATURN (Skills And Training Underpinning a Renaissance in Nuclear), which includes leading nuclear research universities in the North of England and Scotland. The CDT will also include technical training in the nuclear fuel cycle to ensure all candidates are familiar with the nuclear sector, and specialist research skills training.
