University of Birmingham Industry Lecture

Cerberus Nuclear has recently provided support to the University of Birmingham’s nuclear post-graduate masters courses. Geoff Hall and Katrina Christaki presented a lecture to students of the PTNR (Physics and Technology of Nuclear Reactors) and NDWM (Nuclear Decommissioning and Waste Management) courses as part of an ongoing industry lecture series. 

They gave an introduction to radiation shielding and criticality safety assessment in industry which was supported by case studies on the innovative projects that have been carried out by the Cerberus team over the past 12 months.

In particular, dynamic source movement assessment techniques were described and the benefits for use in radiation transport assessment were of focus, as well as a worked example of a dynamic waste package loading and transfer process within a facility with changing dose rate contours displayed live as package movements take place.

Cerberus's criticality training aid, CARTA, was also presented. CARTA is a brand new innovative tool that uses machine learning to calculate k-eff in real time for the purposes of operator training. CARTA is currently in development supported by NNL, AWE and Sellafield Ltd as part of the Alpha Resilience Capability. An early desktop version of CARTA was demonstrated to students providing an insight into the fundamental principles of criticality safety.

The lecture was well received by the students and provided an excellent demonstration of the unique and innovative work that individuals joining the team can look forward to getting involved with.

Cerberus supports summer placements from the NTEC (Nuclear Technology Education Consortium) postgraduate-level masters degree course, and we look forward to doing the same for the University of Birmingham later this year.

OpenMC Fusion Technology Course

Cerberus Nuclear recently provided OpenMC support to the Fusion CDT course at the University of York. As part of the course the students attend a week-long fusion technology module to learn about all aspects fusion including reactor technology, plasma physics and neutronics modelling. The week concluded with a workshop on the open-source neutronics transport code OpenMC

The OpenMC workshop was run by John Billingsley (Cerberus Nuclear) and Jon Shimwell (Firstlight Fusion). Together they presented a course on OpenMC teaching fusion neutronic transport analysis as well as providing the students with valuable insights from their industry experience. 

The students covered the use of Paramak for fusion reactor parametric geometry creation.

The workshop was aimed at beginners covering a wide range of topics including transport theory, running neutronic simulations, understanding material cross-sections, creating simulation geometries, scoring tallies, source definitions plus many more. 

The course was very well attended with students from master's to PhD level looking to gain industry experience and knowledge related to the exciting and rapidly developing field of nuclear fusion.

"After delivering the workshop remotely in 2021, it was great to be back at University of York. The workshop was a great success, with students developing from having little or no neutronics knowledge at all, to having a fundamental understanding of neutronics and its application, and being able to perform a variety of studies using OpenMC.

Many thanks to Prof. Bruce Lipschultz for inviting us back."

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.

Look out for future updates, if you would like to learn more don't hesitate to get in touch at
