Cerberus Nuclear Delivers Criticality Training to Tradebe Inutec

In addition to criticality safety consultancy services, Cerberus Nuclear has expertise in delivering criticality safety training. Our in-house graduate criticality assessor training (aka “Crit College”) is delivered in line with the Working Party on Criticality guidelines, and our more senior assessors are experience in mentoring our graduate recruits.

We have also developed CARTA, a criticality training aid, available in VR and desktop-based versions. CARTA software is available for purchase and Cerberus Nuclear can provide advice on how to integrate it into your own criticality training programme. In addition, we are able to utilise CARTA when delivering training for our clients.

Recently, our Criticality Safety Lead, Toby Tyas, delivered criticality safety training to the SHEQ department at Tradebe Inutec. The first part of the training was held over Microsoft Teams and focussed on the factors that affect criticality. The second training session was held on site and was centred on the principles of fissile mass control.

Toby used CARTA VR to enhance the training. A strength of CARTA is that it allows people to apply the principles discussed in conventional classroom presentations through exercises within the CARTA simulations. We think this makes for more enjoyable and effective learning. On the day trainees were very positive about CARTA and said that they particularly liked the intuitive nature of the spheres in the MAGIC MERV Scenario. CARTA can also be configured for use in a seated position, so people who might be a little nervous about VR can feel confident enough to take part.

As part of the exercise Toby had placed some error traps along the way, which the team successfully identified and resolved, so full marks! Toby is very grateful for the warm welcome and active participation of everyone who attended the training session.

Cerberus Nuclear attend ANSWERS Seminar

Cerberus Nuclear recently had the privilege of attending the 57th Meeting of The Shielding Forum and the 103rd Working Party on Criticality (WPC) meeting during the annual ANSWERS seminar held in Bournemouth. Over the course of three days, professionals from the nuclear sector gathered to discuss key topics such as radiation shielding, reactor physics, and nuclear criticality, as well as recent developments and applications of ANSWERS software.

As a proud sponsor, we also had the chance to showcase CARTA, our in-house criticality safety training tool, and the many ways it can address the unique challenges facing the nuclear industry.

The event’s comprehensive program was well received by attendees who praised the insightful presentations and dynamic discussions. This conference was especially meaningful as it addressed pressing industry concerns such as skill gaps in critical areas.

Thank you to Frances Yates for organising such an informative event, and we look forward to continued partnerships with the Nuclear Institute YGN and supporting future events that advance knowledge and collaboration in the nuclear sector.

Cerberus Nuclear present to Birmingham's post-graduate nuclear masters courses

Recently, Cerberus Nuclear provided support to the University of Birmingham’s post-graduate nuclear master courses (the Physics of Technology of Nuclear Reactors and Nuclear decommissioning) through a lecture presented by Katrina Christaki, Jacob Westerman, and Zachary Strangwood as part of an industry lecture series. 

During the lecture, the Cerberus team provided an introduction to radiation shielding, Monte Carlo codes and criticality safety assessment in industry, which was supplemented by case studies of their innovative projects in the past 12 months. 

Jacob highlighted dynamic source movement assessment techniques, their usefulness in radiation transport assessment, as well as demonstrating the shielding verification procedure by emphasising the training, equipment and safety measure required to conduct the process.  

Zachary, a recent graduate of the PTNR course, offered industry insight into how to accurately model and setup an example shielding problem by using Monte Carlo techniques. Additionally, Zachary discussed his dissertation project which consisted of modelling various radiation shielding scenarios with a moving source in MCNP. 

Katrina presented an introduction to criticality safety, highlighting the factors affecting criticality and where criticality safety fits into the industry. Furthermore, Katrina presented CARTA, a Cerberus developed criticality training tool that employs machine learning to calculate k-eff in real-time for operator training and provided an opportunity to the students to test the tool with a VR headset. 

The lecture was well-received by the students, providing them with an excellent understanding of the unique and innovative work done by the Cerberus team. 

Additionally, Cerberus plans to supervise similar dissertation projects to the one Zachary completed last year, supporting the University of Birmingham and the NTEC master’s courses. If this is something you may be interest in whether a student of one of these courses or not, please get in touch.   

Sellafield Ltd Supply Chain Forum Special for International Women's Day

Our criticality safety assessors Katrina and Haleema represented Cerberus at the Sellafield Supply Chain Event in March. The event was a women’s special, falling just after international women's day, and was only attended by women in the supply chain and at Sellafield Ltd.

It was so great to hear from different SMEs and all the great projects currently going on. It was especially great hearing from the next generation coming up through the Sellafield apprentice schemes. We wish them all the success in their next chapters! Another fantastic presentation was from the Jacobs women’s network, and we look forward to hearing and collaborating more in the future.

At the forum, companies are given the opportunity to give a 60 s pitch. Katrina Christaki took the challenge and pitched Cerberus Nuclear to the other attendees at the forum!

Cerberus looks forward to continuing collaboration with Sellafield and to attending the next supply chain forum. 

Nottingham Trent University Presentation

Cerberus Nuclear is excited to have delivered a technical and industry focused presentation to the Physics with Nuclear Technology students at NTU. Building on the student’s knowledge of radiation transport they were introduced to Monte Carlo calculations in the context of shielding assessments. The presentation was well received with thought provoking questions being raised by the students.  

After the presentation the students also got to learn about Criticality safety through our CARTA VR experience. As NTU alumni Nathan and Sam got the chance to provide an insight into their career paths and introduce the students to the world of Nuclear Consultancy.  

We would like to thank Dr Edward Breeds and Dr Nick Evans for welcoming us back to campus and facilitating our presentation.

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.

We have recently completed the software development for two training scenarios. This programme of work has been funded by the UK’s Alpha Resilience and Capability (ARC) programme.

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:

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.

Initial CARTA Concept

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.
