Revolutionising 3D Dose Rate Visualisation

Radiation Safety and Efficient Delivery

The nuclear industry is faced with the challenge of ensuring radiation safety and efficient delivery while dealing with the complexities of designing and operating nuclear facilities. In this context, dose rate visualisation plays a vital role in evaluating and visualising radiation sources and their impact on the surrounding environment. This information is crucial in making informed decisions to maintain a safe working environment for the workforce and the general public. 

However, traditional methods for dose rate visualisation often result in bottlenecks and inefficiencies in the workflow. To address these issues, Cerberus Nuclear is committed to revolutionising the field by developing cutting-edge tools that simplify the production of 3D dose rate contour visualisation. This approach will allow our radiation shielding assessors to perform accurate assessments quickly and effectively, leading to better outcomes for our clients. 

At Cerberus Nuclear, we understand the importance of dose rate visualisation and are dedicated to providing innovative solutions that address the challenges faced by our clients. Our goal is to streamline the process and make it easier to visualise dose rates in real-world applications, thereby improving the overall safety and efficiency of delivery.

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.
