Strathclyde Chancellor's Fellow

Civil and Environmental Engineering

Personal statement

I joined the University of Strathclyde in April 2014 as a Senior Lecturer. I am a microbiologist and radiochemist with extensive experience of research into microbial interactions with radionuclides and metals, working at the interface between microbiology and analytical & radio-chemistry.

My research is mainly focused on understanding how microorganisms can affect the chemistry and transport of radionuclides in the environment. These microbial effects can be exploited to develop novel methods for limiting the migration of radionuclide contaminants in the environment and to treat radioactive wastes.

Other recent research projects have investigated the interactions of silver nanoparticles with bacterial biofilms, remediation of petroleum contaminants and microbial transformations of metals.

Underpinning the safety case for the use of colloidal silica based grout for waste containment

X-ray Computed Tomography beamtime awarded by Diamond Light Source (STFC) at equivalent funding value of £95,940.

Abstract of funded proposal:
In the proposed experiments we aim to develop the scientific case to underpin the use of novel colloidal silica based grouts for radioactive waste containment. We aim to use the element specific capabilities of synchrotron based X-ray CT at beamline I13-2 to investigate the effects of the grout injection on the geochemistry of Sr, Cs and U. We will also utilize the time resolved capabilities to determine the influence of complex solid matrices on the (injection) behaviour of the silica grouts.

Development of Novel Treatments for Carbon-based radioactive wastes
Renshaw, Joanna (Principal Investigator) Lunn, Rebecca (Co-investigator) Switzer, Christine (Co-investigator)
"The nuclear energy and weapons programmes of the past 70 years have created a legacy of waste and contamination around the world. Amongst the very diverse and complicated wastes arising from these programmes are a range of orphan wastes. These are wastes which are not suitable for treatment in existing processing plants and for which there is no currently accepted treatment option.

This project will determine the feasibility of a wholly new approach to treatment of orphan radioactive wastes. The overarching longer-term research vision is for a three-stage waste treatment process. First, smouldering the waste (in the same way that coal smoulders in a fire) to burn the carbon and produce a small volume of stable radioactive ash that can be encapsulated (generally in cement) and placed into a container (comprised of steel or concrete) for future geological disposal. Second, capturing safely the radioactive emissions that are released by the smouldering process. These are in the form of microscopic particles of radionuclides and carbon dioxide gas that contains the radioactive element, Carbon 14. This capture will make use of similar technologies to those being explored to remove carbon dioxide from the atmosphere to tackle climate change. Bacteria will be used to stimulate the production of carbonate and/or phosphate minerals, removing the radioactivity from the gases and capturing them into a stable mineral (i.e. into a rock) . Finally, this process of capturing the radioactivity into a mineral will be performed as part of the encapsulation process either for the radioactive ash (prior to placing it in a container) or for other radioactive wastes, so as to reduce the final volume of radioactive material that requires disposal.

In order for any treatment process of orphan wastes to be accepted by the UK regulatory authorities, it is critical that no radioactive gases are emitted. Hence, this research project will focus on demonstrating the feasibility of capturing (1) 14C as a stable carbonate and (2) other particulate radioactive emissions into stable phosphate minerals. The project will focus on demonstrating feasibility for a single wasteform, graphite, which is the largest volume orphan waste. If feasibility can be demonstrated, other research projects will follow to explore the smouldering process and the use of the carbonate and phosphate minerals for encapsulation of the radioactive ashes, created by the smouldering process."
