The future of nuclear energy depends on safe, efficient, and environmentally sustainable waste management, but cleaning up contaminated materials remains a major challenge. What if we could use plasma — the same state of matter found in lightning and the sun — to tackle nuclear waste? This PhD project explores how atmospheric pressure plasmas (APPs) — high-energy, electrically charged gases — can revolutionise nuclear decontamination in a cleaner, safer, and more sustainable way.<br /> <br /> This project will revolve around a ground-breaking application. It will investigate whether APPs can remove radioactive contamination from materials used in nuclear sites. This will lead to the reduction of chemical waste and will allow for minimising environmental impact. Moreover, it will explore whether APP treatment can transform nuclear decommissioning, allowing easier disposal and if possible, even achieve repurpose, contributing to a more circular and responsible nuclear economy.<br /> <br /> This project is highly interdisciplinary, combining plasma science, nuclear engineering, materials science, and environmental sustainability. The student will gain hands-on experience on the design and optimisation of plasma systems, running cutting-edge experiments, and using advanced analysis techniques. Working within the SATURN CDT at the University of Leeds, you will collaborate with experts in materials, plasma surface modification, and nuclear waste management. <br /> <br /> Enthusiastic students from physics, chemistry, materials science, all fields of engineering, and related fields are welcome to apply. To everyone who is willing to work on a transformative technology that can change the future of nuclear cleanup, and contribute to a safer, cleaner, and more sustainable world, this PhD is for you!<br />
<p><strong>Hypothesis</strong></p> <p>Atmospheric pressure plasmas (APPs) can effectively reduce radioactive contamination on solid materials from decommissioned nuclear sites, offering a potential alternative to conventional decontamination methods for safer disposal or repurposing.</p> <p><strong>Aim</strong></p> <p>The aim of this project is to design and optimise an APP system that is suitable for treating metal, ceramic, and polymer contaminated materials, taking advantage of different plasma conditions, i.e. pressure, power, treatment time, as well as chemistries, i.e. Cl2 works better for metals, O2 for polymers, and SF6 for ceramics.</p> <p><strong>Overall Impact</strong></p> <p>This PhD project will not only produce quality publishable outcomes that will progress the fields of plasma science, materials science and engineering, nuclear engineering, but will also provide nuclear engineering with an invaluable new tool. It will promote and advance the use of atmospheric pressure plasma as an innovative tool for nuclear waste decontamination, potentially providing a safer, more effective, and environmentally sustainable alternative to conventional cleaning methods. This is one of the many parallel steps that the field must take in order to transition into a more sustainable reality in our general effort to transition into a sustainable civilisation.</p> <p><strong>CDT information</strong></p> <p>This project is part of the Centre for Doctoral Training (CDT) in SATURN (Skills And Training Underpinning a Renaissance in Nuclear). It is led from the University of Manchester and includes leading nuclear research universities in the North of England and Scottland (University of Leeds, University of Sheffield, Lancaster University, University of Liverpool, University of Strathclyde). We aim to deliver the next generation of nuclear researchers to help the UK achieve its Net Zero targets and beyond, in a collegial cohort environment. 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.</p> <p><a href="http://www.saturn-nuclear-cdt.manchester.ac.uk/">SATURN_Nuclear_CDT</a></p>
