Scaling the erosion & mobilisation of highlight active simulant suspensions with impinging vertical jets, to enhance nuclear waste processing

Project Overview
Within various nuclear waste processing operations, such as the Highly Active Storage Tanks at the Sellafield THORP fuel reprocessing facility, impinging liquid jets are used to disperse and mobilise sedimented particulate dispersion wastes. This research project is an industrial collaboration with Sellafield Ltd and the National Nuclear Laboratory, and seeks to fundamentally understand the many complex factors that dictate the erosion and dispersion mechanism of sediments in these complex multiphase tank systems. This work is critically important to aid both current operations and for future Post Operational Clean Out of the tanks.

Specifically, knowledge of particle surface forces and liquid dynamics will be used to build an engineering model using different scaled jet-systems, which will allow prediction of the full-scale plant process operations. This work will combine a number of complimentary techniques to fully characterise the simulant beds and erosion jet systems, significantly improving current understanding of the HASTs. Additionally, the work will have a number of complimentary applications in other nuclear waste systems and many other non-nuclear environments, where characterising erosion of sediments is important; from predicting attrition in waste reservoir outlets to measuring long term bed-slip in estuaries.

Applications are invited from candidates with a good first degree in a science or Engineering discipline, such as Chemical Engineering, Mechanical Engineering, Materials Science & Engineering, Chemistry and Physics. For more information, please contact the project supervisor: Dr Timothy Hunter T.N.Hunter@leeds.ac.uk.

Next Generation Nuclear
The centre’s mission is to develop the next generation of research leaders to support the UK's present and future strategic nuclear programmes - cleaning up the nuclear legacy, building new nuclear power stations, and defence and security.
This exciting opportunity will involve close collaboration with key industrial stakeholders, including secondments into industrial nuclear research centres.

Further Information
Indication of interest and initial enquiries should be made by sending a CV, a covering letter and university transcripts to Abby Ward preawa@leeds.ac.uk at the Institute of Particle Science & Engineering, School of Chemical and Process Engineering, University of Leeds.

Application Deadline
31st July 2014 or until the position is filled.
