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.
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.

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 (firstname.lastname@example.org).
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 email@example.com.

To learn more about ANDI and our latest developments combining computer vision with 360 video go to ANDI360.
ANDI: 360 Tracking
This is our latest post regarding our software ANDI (Automated Nuclear Damage Inspection) and incorporating identification capability with 360 video data.
The 360 camera sector has advanced significantly over the past few years, camera resolution and image quality has improved greatly as well as advancements in software processing to provide multiple different ways of viewing the captured images and video. Cerberus Nuclear has been keeping up to date with latest developments with an aim of using this technology in the nuclear sector.
Cerberus recently developed ANDI (Automated Nuclear Damage Inspection) for Sellafield Ltd. The software automatically identifies key areas of damage from inspection videos and is currently being used by Sellafield to accelerate damage inspection tasks. The software is built into a user-friendly interface and supports the creation of reports and logging of key identified features.
Building upon our knowledge we are currently testing the use of 360 camera and video data with our custom computer vision algorithms, including ANDI. Some key advantages of using 360 data for automated damage inspection is that the orientation of the inspection camera is no longer a factor as images capture the full 360 degrees.
Similar technology is currently being used in autonomous vehicles for object identification and distance determination.

Our preliminary testing has proved to be very successful and we have overcome some of the challenges inherent in working directly with 360 data sets. The prototype software we have created demonstrates the capability of combining both 360 image technology with our bespoke computer vision algorithms.
Our goal is to continue the development of ANDI so this highly useful and innovative technology can be put to good use solving a wide range of challenges in the nuclear sector and beyond.
Sellafield LINC: Image Processing for Assessing Package Integrity
LINC with Sellafield Ltd is a scheme that encourages SMEs at local and national level to collaborate and deliver innovative solutions to support the mission at Sellafield. LINC challenge 42 was titled ‘Image Processing for Assessing Package Integrity using Machine Learning’ and set the challenge as follows:
“The long-term storage of nuclear waste is at the heart of the nuclear industry in the UK. As a requirement this material must be examined on a regular basis, which generates a vast amount of data to be reviewed. Presently this is done manually and takes a lot of time and is vulnerable to human error."
Cerberus Nuclear’s Data Science team proposed the development of software containing a trained machine learning computer vision model that would be capable of automatically recognising issues that could affect integrity of the package. Our team use the ‘Agile’ design methodology, which incorporates software testing in short, focused development cycles; ideal for the project.
We were delighted when Sellafield Ltd chose our solution ahead of some tough competition.
ANDI: Automated Nuclear Damage Inspection
ANDI is a high-quality user-friendly software program that utilises computer vision machine learning for automated identification of damage from externally supplied video.
The software allows detailed examination of product can inspection videos, automatically identifying damage such as scratches, dents and corrosion. The neural network within ANDI uses a cutting-edge R-CNN approach for image analysis and was trained using previous examples of damage.
Damage identified is highlighted within an embedded video player, which allows users to quickly skip to areas of interest and examine results frame by frame to inspect the exact moment(s) that damage has been detected. The confidence level of identified damage can be customised by the user with damage highlights switched on or off to assist with detailed inspection.
An integrated inspection report system was incorporated into the software to allow users to make notes and log frames for easy follow up review. The software also allows the processing of multiple batches of inspection videos with minimal user interaction. This allows the review of multiple processed results within a single session.
The algorithm for the Sellafield challenge uses an extension of the R-CNN called the Mask R-CNN. The R-CNN algorithm (Region based Convolutional Neural Network) can detect and classify objects within images, it focuses on variations of colour, texture and scale within an image to form a region.
“I really like the look and feel of the software and I’m impressed how well the neural network is identifying the key elements of damage, it’s very good!”
“We are delighted that Cerberus Nuclear helped make a difference at Sellafield Ltd. The Data Science team have delivered a great solution, bringing modern techniques to the nuclear industry.”
Daniel Cork, Director, Cerberus Nuclear
Sellafield Ltd are currently using ANDI to enhance their damage inspection workflow which, prior to using the software, had taken many man-hours to identify, categorise and log.
Cerberus Nuclear are proud to announce ANDI has recently been a key feature for inTechBrew. inTechBrew promotes the latest high Technology Readiness Level (TRL) nuclear industry innovations across UK and Europe.
Machine Learning Computer Vision
Previously, the team developed a custom computer vision object identification algorithm to identify cars and lorries on a motorway using R-CNN object detection method.
The algorithm identified the number of objects, object type (car, lorry, etc.), object colour, object speed and confidence in match. In addition, a report was generated that summarised the information gathered over time. The development was to demonstrate validity of use for stopped car identification as well as traffic monitoring purposes.
The Sellafield Ltd LINC challenge aligned well with the previous development work already performed and paved the way for the creation of ANDI. Additional technical challenges such as variable lighting, frame blur and reflections had to be overcome as well as creating a custom user-friendly interface that met with Sellafield Ltd requirements. The processing time for the computer vision algorithm was also enhanced.
Cerberus Receives ARC Funding to Develop Criticality Safety VR Training Software
Cerberus Nuclear is a hub for innovation in criticality safety and radiation shielding and we are pleased to announce that we have made a successful application for funding from the UK’s Alpha Resilience and Capability (ARC) programme. ARC was created by BEIS (Department for Business, Energy & Industrial Strategy) to ensure that the UK retains its world-leading alpha capabilities: from operations and maintenance, to high-end R&D and design. This cross-industry consortium includes the National Nuclear Laboratory, Sellafield Limited, AWE and ONR.
Over the last two years Cerberus Nuclear has developed CARTA, a concept for criticality safety VR (Virtual Reality) training software, which we successfully presented at ICNC2019. Uniquely, CARTA uses a machine learning algorithm to predict k-effective 'on the fly' for a given system, such as an alpha facility glovebox. When coupled to a VR headset, CARTA gives users an immersive experience of the facility environment and the effect of their actions on the system’s reactivity.
The ARC funding will support the next phase of development, to refine the concept into a software package for members of the ARC consortium to use. CARTA will deliver tangible benefits directly to operators on plant, criticality safety specialists and other stakeholders in criticality safety. The software package will use a variety of scenarios in desktop and VR environments, to provide intuitive user interfaces. The underpinning data will be based on accurate modelling of the neutron physics, providing a realistic environment for trainees to improve their understanding of the complexities associated with criticality safety.
The specifics of the training scenarios will be guided by a Technical Steering Committee, comprising stakeholders from the various ARC member organisations. This will ensure that the training scenarios are relevant and can be effectively integrated into their existing training programmes.
We are now actively seeking organisations that would benefit from bespoke criticality safety training scenarios. If you would like to discuss your idea, please get in touch using firstname.lastname@example.org.
