Combined Radiation and Corrosion Effects in Advanced Alloys for Molten Salt Nuclear Reactors (Dual PhD Programme) University of Liverpool in United Kingdom

This Dual PhD project, offered jointly by the University of Liverpool and National Tsing Hua University (NTHU) in Taiwan, investigates the combined effects of radiation and corrosion in advanced alloys for molten salt nuclear reactors (MSRs). MSRs represent a promising Generation IV nuclear technology, utilising molten salt coolants (such as FLiNaK) to achieve higher thermal efficiency and enable the use of alternative fissile isotopes. A major challenge is the development of structural materials capable of withstanding the highly corrosive and radioactive salt environment while maintaining mechanical and chemical integrity over extended periods.

The research focuses on understanding molten salt corrosion, a complex process involving element loss from structural alloys, wall thinning, and surface layer modification. Real MSR systems experience continual changes in salt chemistry due to burn-up and radiation, presenting new challenges for material durability. In collaboration with Copenhagen Atomics, the project will study corrosion behaviour in both conventional and advanced low activation high entropy alloys under realistic reactor-like conditions. Experimental work will be designed to develop a synergistic understanding of how evolving salt chemistry and radiation impact corrosion kinetics and atomic-scale modifications.

Students will benefit from a unique training environment, spending two years at NTHU (under Prof. Fan-Yi Ouyang) focusing on alloy design, fabrication, irradiation, and advanced synchrotron characterisation, followed by two years at Liverpool (under Dr Maulik Patel) emphasising electron microscopy, diffraction analysis, long-term corrosion studies, electrochemistry, and combined testing. Access to complementary facilities across both institutions—including ion irradiation, NSSRC, molten salt loops, and advanced microscopy—will provide unparalleled research opportunities.

The programme offers a full tuition fee waiver for four years and a maintenance stipend: TWD 15,233/month during the two years in Taiwan, and the UKRI Studentship rate (£20,780/year for 2025-26, rising with inflation) during the two years in Liverpool. Additional funding is available for research consumables and conference attendance. Scholarships are available for outstanding international students, and the institutions are committed to inclusivity, offering support for students with disabilities or caring responsibilities.

Applicants should have a strong academic background in materials science, engineering, chemistry, or physics, and an interest in experimental research. The position is open to both home and international students. To apply, candidates must complete the University of Liverpool online postgraduate research application form for a PhD in Materials Engineering, including the project title and reference number NTHU001. The application deadline is March 15, 2026.
