PhD Opportunity in “Advanced Ultrasonic Characterisation of Slurry Flows”

Contract type:    Tax free scholarship managed by NNL

Funding amount: £15,009 per annum plus UK/EU tuition fees

Application Deadline: 31st October 2019

University: University of Leeds – School of Chemical and Process Engineering

Academic Supervisor: Dr Tim Hunter

Scope: The aim of this project will be to integrate innovative acoustical modelling into software tools for real-time feedback of radioactive particle levels and their state of aggregation, for remote process control as they are transported as slurries. This work will include the use of novel machine learning techniques for acoustic data analysis and pattern matching, whereby the influence of a number of acoustic parameters on the backscatter signal can simultaneously be assessed.

PhD Opportunity in “Analysing Radioactive Laser Cutting Emissions”

Contract type: Tax free scholarship managed by NNL on behalf of the NDA

Funding amount: £18,009 per annum plus UK/EU tuition fees

Application Deadline: 2nd December 2019

University: Loughborough University – Mechanical and Manufacturing Engineering

Academic Supervisors: Dr Lewis Jones, Dr Ed Long and Professor John Tyrer

Scope: There is a considerable challenge in the development of new technologies for the safe decommissioning of contaminated radioactive infrastructure. Laser cutting has been selected as one of the new enabling methods due to the accurate and flexible cutting and process control that can be achieved with remotely controllable process. However, the exact amount and sizes of the fume and dust is not well understood as they vary from nano-particles up to mm size.  When cutting contaminated stainless steel how far do the volatile components from the steel such as Cr and Ni or radionuclides such Cs and Sr migrate during cutting. Use of state of the art particle measurement tools at Loughborough will help do this.  Ultimately, the aim of this PhD research project is to look into “bad cutting” for “good fume”.  This is achieved by characterising, analysing and experimentally validating the fluid and particulate emissions generated during laser cutting for the purpose of understanding the hazard potential during radioactive facility decommissioning.  Laser cutting produces less fume than most other techniques but it is actually difficult to quantify exactly by how much.

PhD Opportunity in “Advanced Laser Processing Control Strategies for Radioactive Decommissioning”

Contract type: Tax free scholarship managed by NNL on behalf of the NDA

Funding amount: £18,009 per annum plus UK/EU tuition fees

Application Deadline: 2nd December 2019

University: Loughborough University – Mechanical and Manufacturing Engineering

Academic Supervisors: Professor John Tyrer, Dr Ed Long and Dr Lewis Jones

Scope: The aim of this project is to develop a laser cutting process that minimises the hazardous nano-particulate emissions that are produced during ‘standard’ laser cutting mechanisms. This will include identification of Key Process Variables, emission mechanisms and hazards in order to develop a strategy for process control. It is expected that this work will involve significant experimental investigation into optical beam shaping using holographic methods, gas delivery and fume emission collection techniques to develop a new process of low emission cutting. Ultimately, the aim of this PhD research project is to look into ‘bad’ cutting” for “good fume”.  To optimize the cutting to get better sized fume we need an effective real-time control system.

PhD Opportunity in “An Acoustic Analysis Tool for Detecting Hydrogen Gas in Sealed Pressurised Storage Packages and Containers”

Contract Type: Tax free scholarship managed by NNL on behalf of the NDA

Funding amount: up to £17,666 plus UK/EU tuition fees

Application Deadline: 11th November 2019

University: London South Bank University – School of Engineering

Academic Supervisor: Dr Paul Holborn

Brief Synopsis: Flammable hydrogen gas, generated through the action of radiolysis and corrosion reactions, can readily accumilate in and pressurise the sealed product packages (cans and drums) that are present at Sellafield and other nuclear plants in the NDA estate. The aim of this project is to develop a screening tool for characterisation and detecting accumulated hydrogen gas in sealed pressurised storage packages and containers. A programme of experimenal tests will be carried out using an array of piezoelectric transducers applied to the surface of representative containers which will then be excited with an instrumented transducer at different frequencies. The resulting acoustic vibration measurement data will be analysed to obtain correlations and build a model to relate the observed acoustic behaviour with the hydrogen concentration and pressure inside the container. This information will then be used to develop a tool/algorithm for detecting the presence of pressurised hydrogen in a container, whilst providing information on its likely composition and pressure.
