We are happy to announce that Nathan Chambers has joined Cerberus Nuclear following a successful summer placement with the company. During his MSc Placement, Nathan performed an investigation into the effect of localised radiation shield weaknesses on the dose uptake of a self-designed phantom model.
Nathan has been involved in the latest phase of the Bright 3Ts Hospital shielding verification work since starting with the company. He is also supporting a Nuclear Characterisation project, and will be developing his Radiation Shielding skills in the coming weeks alongside continuing his MSc research by producing a guidance note on his findings. Welcome to the team Nathan!
New Starter – Zachary Strangwood
We are pleased to announce that the first new starter of this year’s graduate intake has started with the company. Zachary Strangwood completed his MSc placement with the company this summer. His project consisted of modelling various radiation shielding scenarios with moving sources in MCNP and creating an interpolation engine using Python to calculate mesh tally data for different source positions in these scenarios. We are delighted that Zachary decided to stay on with the company following his Masters project!
Zachary is starting work supporting the Radiation Shielding team, but is looking forward to also supporting Criticality Safety as he progresses along the graduate scheme.

Cerberus Present at the American Nuclear Society Annual Meeting
We recently presented two papers at the American Nuclear Society Annual Meeting in Anaheim, California. The papers were presented within the Nuclear Criticality Safety Division (NCSD) Topical Meeting and were titled:
CARTA – Criticality Safety Virtual Reality Training Aid, Recent Developments.
Cyclone – Monte Carlo Data Processing and Visualization.
Katrina presented the CARTA paper and won the best paper award within the ‘Knowledge Transfer – Education, Professional Development, and Training’ track. The trophy (a prestigious NCSD thermos mug!) was presented at the NCSD awards dinner. The UK was well represented at the conference, with Katrina picking up her award alongside Amy van der Vyver from Sellafield Limited who presented a paper on the ‘UK Working Party on Criticality Webinar Series to Support Continuing Professional Development’. Liam Payne of Nuclear Waste Services (NWS) presented a UK perspective on Post-Closure Criticality Safety, and Alfie O’Neil from NNL presented a paper on Benchmark Experiments.
Cyclone and CARTA were really well received. Cyclone visualisation of MCNP models featured in a presentation by colleagues at the University of New Mexico. Stewart and Katrina were on hand with VR headsets to demonstrate CARTA, giving attendees the chance to (safely) cause a criticality in a glovebox.
Thanks to the ANS and, in particular, our colleagues within the NCSD who made us feel very welcome at the conference.

Cerberus Nuclear Support NNL Criticality Safety Training Course
We recently supported NNL with delivery of their UK Nuclear Criticality Safety Course. This is a long established training course in the UK and is supported by the University of New Mexico. Guest speakers from Sellafield Limited and ONR also contribute to the course.
Representatives from NNL have been key stakeholders in the development of CARTA, our criticality training application, via an Alpha Resilience and Capability (ARC) funded programme of work. Integration of CARTA into their criticality training course has been a key milestone for this programme of work and we were pleased to deliver this novel project on time.
At the criticality training course, we were delighted to see our ‘MAGIC MERV simulation’ being put into good effect in presentations regarding the factors that affect criticality. The ‘glovebox process simulation’ provided an interesting and lively group activity with the course instructors creating a series of challenging scenarios for the class to tackle. You can read more about the training simulations here.
In addition, Sam and Stewart were on hand to demonstrate the simulations in a Virtual Reality (VR) environment (both during the course and in the bar at the end of the day).
We would like to extend our thanks to NNL for their support in the development of this phase of the CARTA project and for hosting us on the course.
Completion of ARC funded CARTA Software
CARTA is criticality safety training software developed here at Cerberus Nuclear. Uniquely, CARTA displays a realistic value of k-effective as the user interacts with the simulation, either in a conventional first-person desktop format or Virtual Reality (VR) environment. The user can see, in real-time, the effect that their actions have on criticality safety. The CARTA methodology requires a multi-disciplinary approach, combining criticality safety calculations, machine learning and a gaming environment.
The project has involved engagement with representatives from many of the ARC member organisations. This has given relevant stakeholders the opportunity to influence the functionality and appearance of CARTA as a training tool, prior to integration into training programmes within their own organisations. Two training simulations have been created:
The ‘MAGIC MERV’ simulation – Users can interact with two spheres of fissile material in a laboratory environment. The simulation is able to demonstrate the behaviour of all of the factors that affect criticality, i.e.
Mass
Absorption
Geometry
Interaction
Concentration
Moderation
Enrichment
Reflection
Volume
This simulation is intended to be conceptual rather than realistic. It allows the maximum range of effects to be demonstrated, making it useful for training operators and assessors and also for wider stakeholder engagement.
The glove box process simulation – Users interact with a realistic glove box featuring a mass balance, assay chamber and array of stored cans containing fissile material. They are presented with an imported can and are able to weigh and assay the can in order to determine if it is ‘safe’ before storing it or rejecting it. The simulation allows trainees to be challenged with various configurations to enhance their understanding of criticality rules, potential fault scenarios and some of the challenges with fissile material assay.
Images of CARTA development. From concept through to the final product.
We are now looking at options for implementation at each of the various ARC member organisations including Sellafield Limited, AWE, NNL, Nuclear Waste Services, ONR and DSRL. If you work for any of these organisations and would like access to CARTA, then please get in touch (nuclear@cerberusnuclear.com).
We are now actively seeking organisations that would benefit from this particular software or bespoke criticality safety training scenarios using the CARTA methodology. If you would like to discuss your idea, please get in touch using nuclear@cerberusnuclear.com.
Cerberus Welcomes Employee Shareholders
January saw the first anniversary of our company EMI share option scheme, which is a government approved way of rewarding employees with share options. We are delighted that some of the team have exercised their options, becoming full shareholders of the company.
“We’re always looking into ways to genuinely recognise and reward our growing team. Sharing ownership of the company seems like a unique benefit that we can offer, and we’re really pleased that so many of the team are invested in the long-term success of the company” – Stewart Hay, Director.
“Personally I’ve always loved the benefits of working for a small technical consultancy. Among these is the financial transparency with company progress and project forecasts. Cerberus Nuclear’s EMI share scheme has taken these benefits to new heights by providing the opportunity for me to invest in the company directly and become a shareholder. The prospect of a nice pay out in future is definitely exciting!” – Sam Hilton, Consultant and Shareholder of Cerberus Nuclear.
Future U Mentoring Programme
Cerberus Nuclear recently supported the STEMFirst led Future U Mentoring Programme through the stem ambassador programme. Katrina Christaki delivered a presentation to Blackburn College as part of an ongoing series for educating and inspiring young people on different STEM career paths. The aim of the series is to develop the skills and increase the aspirations for a cohort of students that are less likely to consider higher education options, whether that be university or apprentice opportunities.
This particular session focused on the core skills used in multiple jobs in STEM, including teamwork, problem solving and coding. Katrina joined other STEM ambassadors in a ‘this is me’ presentation describing her job role and where these skills applied. While answering questions she also provided advice on describing these skills during interview. Katrina has this presentation available for use in other STEM ambassador events and looks forward to the next one.
