I live in Newcastle-upon-Tyne in the North East of England. I’m married and have two sons. The eldest is in Y12 and the youngest is in Y9.
We have a busy life. One son is a keener swimmer so that is quite a lot of training and going to galas and the other is keen on badminton, squash and tennis and I play the odd game of tennis in the summer which is fun in the sun.
I have been a school governor at a local primary school for more than 10 years. Its interesting to understand the challenges that pupils and teachers face and to try and help them.
I’m struggling to learn to play the guitar – its not so easy to learn things when you’re older – and I find I can’t find enough time to practice as much as I want to make me as good as I want to be. When I was growing up I had piano lessons and never wanted to do my scales…

You may not know that the UK has been involved in nuclear technologies since the 1940s. We have a variety of sites across England that have generated radioactive waste throughout their lifetimes. Some sites are old research sites used to develop the UK programmes of nuclear power generation and nuclear weapons and we also have some operational and closed nuclear power stations. To permanently decommission and clean-up these sites more wastes will be generated. All these wastes need to be managed and disposed of safely.
Of course this is no different to decommissioning and clean-up a site of a former steelworks or coal-fired power station. But of course radioactive waste is very different in the hazards it presents and stakeholder attitudes and views on it.
Here is a link to a blog I wrote some time ago about the work my colleagues and I are involved in.

My Typical Day:
Since the UK response to the pandemic started my days have changed a lot. Now I continue to work remotely – which means all my meetings are held by Teams, Zoom and other webinars. The meetings are a mix of internal meetings with colleagues where we coordinate our inputs into work topics – you work as part of a team in almost everything. We also have external meetings with operators of nuclear sites to get updates on their management of wastes and discuss how they propose to continue decommissioning sites and how they will protect the environment as a result.
We also do periodic training courses as well. I recently attended one which discussed safety cases and we spent some time discussing other safety cases, including some examples when accidents have occured to see if there contributory weaknesses in the safety cases. We looked Buncefield Oil Storage facility fire, the accidents at Chernobyl and Fukushima nuclear power stations, NASA Challenger Shuttle, RAF Nimrod and smart motorways with all lane running.
Prior to remote working I would find myself out on site meeting with operators to discuss waste processing and storage at operational sites or in meetings or site visits related to preparations for geological disposal. I particularly enjoyed visiting some of the research and development work for geological disposal that got me to see large experimental boreholes and field trials being conducted to develop approaches to seal boreholes for the long-term. I’ve put some photos of a large scale experiment in the gallery for you to look at. Without site visits its harder to appreciate the scale and challenges of things but they will return soon.

A current area of interest for me is a new role I have to plan for a periodic review of a long-term safety case for a radioactive waste disposal facility which we require submitting to us in 2026. I know that 2026 may seem like a long time away so why are we getting involved now?! Well these safety cases need to demonstrate that the site will meet our regulatory requirements in the long-term. So it needs to meet our requirements under changed future climates as well as considering other external hazards like earthquakes. We need to make sure that the design of the facility protects the environment both during operation and after it has closed. The safety case isn’t a single report…its likely to be formed from hundreds of reports containing detailed analysis of the disposal inventory, site geology and hydrogeology, facility design and how it will evolve in the future, what the future landscape and climate will be. All this needs to be integrated into a clear summary demonstrating that our requirements have been met.
Before we receive the safety case we are discussing a number of topics with the operator to understand what they are currently doing and how it will change between now and the work being completed. We also discuss with them our comments on their proposals and use our views to develop our list of questions for the final review. We need to cover a range of topics from Quality Assurance to computer modelling to climate scenarios and so we need to involve different experts.
Recently I attended a virtual meeting hosted by the International Atomic Energy Agency which was attended by operators and regulators of radioactive disposal facilities across the world. My group included regulators from France, Belgium, USA, Canada, Australia, Thailand and Lithuania. It was really great to be able to share experiences with others and to see if they can help you answer some of the challenges you have remaining – often they are a great help. Of course normally we’d meet together (in Vienna!) and we hope to do that next time.
Its important to note that the Environment Agency only regulates the areas of radioactive waste management which relates to protection of the environment and therefore we also need to discuss the regulation of health and security with fellow regulators and understand how the two areas interact.
In a non-typical day I could also be involved as part of the Environment Agency’s response to any flooding events. The last I needed to do this was in February and that is completely different to my day job. Or I could be involved in practising our response should there be a radiation incident impacting on England – you will be glad to know that we all practice frequently and I have never needed to respond to a real incident.

What I'd do with the prize money:
Get some more in-person involvement in real life examples of STEM in action in schools.
-
Education:
I went to a state school in Yorkshire and stayed there to do my A Levels.
I’ve been to a few universities. I studied Geology and Geochemistry at Manchester University and then moved to Birmingham University to research Environmental Pollution. More recently I studied Applied Hydrogeology part time at Newcastle University.
-
Qualifications:
I did O’levels, which are old fashioned GCSEs. I’m old! I have 9 of those including Maths, Chemistry, Geology, Physics, English, French, etc…
I have A’Levels in Maths, Chemistry and Geology as well as General Studies (which was a mix of all sorts of things from Art to Technology I think).
I have a BSc in Geology and Geochemistry from Manchester University
I have an MSc in Applied Hydrogeology from Newcastle University
I have a PhD in Environmental Pollution from Birmingham University, my subject was on how soil and particular organic pollutants, called phenols, interact.

Work History:
Whilst studying geology as an undergraduate in one summer holiday I got a job working in the geology department of a potash mine. This involved me helping the site geologist process samples from the working faces and forward plan the works to follow the ore seam. I got to work above and below ground. Below ground meant 1000 m deep and several km under the North Sea! The working conditions underground were like nothing I expected. Health and Safety being a major concern but it was hot with freshly mined rock being 40 degrees celsius. We often rode out to the working faces on conveyor belts and I got to help to set the explosive charges on one work face. It was an amazing experience and gave me a great insight into one area in which geology is applied in a working environment.
After I finished at University I had a temporary job helping to recruit staff for the Forensic Science Service to set up DNA testing labs in Birmingham and London. It was pretty interesting to be involved in it learning about the processes and techniques needed to collect and analyse data to support crime scene investigations. Although I was just doing the admin and not the interviewing I learn a little so I understood back then what a PCR test is and saw how it could be applied to detective work.
My first full-time job was a temporary contract working for BNFL. A company which at the time ran the Sellafield nuclear reprocessing facilities and some other UK sites involved in the nuclear fuel cycle. It wasn’t a career I was aiming for and I am sure I was pretty sceptical about joining the nuclear industry, having previously been in Greenpeace and Friends of the Earth. However, the staff interviewing my won me over and so I thought I was try it. They were great bosses to learn from as I adjusted to working and I got some great opportunities to gain knowledge and experience in how to assess the long-term impacts from radioactive waste disposal. I worked mostly on projects in the UK on BNFL sites but also did some work on sites in the former Soviet Union countries which was a different sort of challenge. Somehow before I knew I had been there for 7 years.
I then moved to work for an Environmental Consultancy based in Edinburgh and by now I was specialising solely in radioactive waste disposal. Whilst continuing to work for UK clients now I also spent more time working on overseas contracts for organisations in Sweden, Poland, Romania, South Korea and Japan. Life in consultancy is much more varied than working in-house in industry and perhaps harder but it was great fun for the 4 years I was there. I did get to visit Sweden several times, spent 2 weeks in Bucharest training Romanian nuclear regulators and in the UK I got to go aboard nuclear submarines that had been taken out of service.

Current Job:
I work in the Environment Agency. My job title is Nuclear Waste Assessor. When I used to tell people this they would look at me blankly or with some fear that I may begin to glow. That makes me laugh – I definitely don’t glow – but also its a bit sad that people’s understanding of science can be limited.
I decided to move to the Environment Agency because geological disposal – the disposal of the most hazardous wastes in a specialised engineered facility several hundreds of metres below the surface – was a growing topic of interest in the UK at the time. Some wastes will remain hazardous for several hundred thousand years and therefore there is a need for management solution and regulation of them to robust address the need to assure safety over geological timescales. I’d not worked on this subject area before and so was keen to. I also thought working for the regulator on that would be a chance for me to apply what I had learnt elsewhere. In terms of variety of challenge it hasn’t failed to disappoint. I have indeed been involved in geological disposal for over 10 years; scrutinising the proposals of the organisation responsible for finding a site and developing a facility; supporting regulation of wastes being prepared for disposal and stored until a facility is ready; and, engaging with members of the public to explain the Environment Agency’s role and answer their queries. I’ve been 14 years now so its become my longest job.
From my 25 years of working on radioactive waste disposal its clear to my that you need a mix of skills and experiences to address challenges. If a single scientific discipline is being applied to radioactive waste disposal then that is probably wrong. The subject area requires detailed knowledge of physics, maths, chemistry, biology, materials science, engineering – of course geology and hydrogeology – but also climatology, project management, and social science disciplines as well as skills in communications and engagement.
