If you have an ambition to bring a Net Zero economy of the future closer, if you are curious about the effects of radiation on reprocessing of spent nuclear fuel and you want to be a part of the UK’s nuclear renaissance, then this could be the project for you.
This PhD project will investigate the radiation stability of advanced separation processes of spent nuclear fuel under industrially relevant conditions. Fundamental knowledge on the effect of radiation on separations processes is necessary in order to underpin the performance and viability of processes at an industrial reprocessing plant scale. Recent studies show that mixed biphasic systems show differences in the radiation stability compared with irradiation of the separate phases or static mixtures. Hence, experimental studies under industrially relevant conditions are highly needed.
The first part of this PhD project will involve the development of a modular irradiation test loop that can be used for both gamma rays and helium ion irradiations of mixed phase systems. This loop will fit both inside common irradiator types and have a window suitable for use on beamline end stations. The project will begin with designing, building and testing a bespoke new UK capability with suitable, versatile online sampling and analytical capabilities. The system will contain all the normal facets of a solvent extraction system; settling/separation tanks, temperature control, mixing regions and a flow loop.
In the second part, the project will move on to an experimental programme of irradiating and testing solvent extraction systems designed and developed both in the UK and internationally, providing data on the radiation tolerance, changes to the physicochemical properties and use within the process.
You’ll be based at the Dalton Cumbrian Facility in West Cumbria which offers unparalleled access to a diverse and experienced industrial expertise base, in particular to the National Nuclear Laboratory (industrial sponsor of this project).
