Cerberus Nuclear recently attended the WPC Workshop on Criticality Safety Assessment Methods, which brought together nuclear industry experts, regulators, and professionals to discuss criticality methodology. The event was hosted at the Pride Park Stadium in Derby and focused on regulatory perspectives, foundational methodologies, and practical applications relevant to the nuclear sector.

The workshop began with the regulatory bodies emphasising aligning safety assessments with evolving nuclear standards and maintaining a proactive approach to risk management through early engagement. It was followed by a series of presentation on different Safety Assessment Methods including Design Basis Analysis (DBA), Design Basis Accident Analysis (DBAA) and Double contingency Principle (DCP). Test case assessment methods were presented. A consideration of conditioning factors applied to Initiating Event Frequency within DBA methodology was introduced, as well as a systematic approach to the analysis of double fault methodology within DBA. The workshop concluded with an introduction to Barrier Analysis and Transport Safety Assessment and a relevant exercise.

In conclusion, the workshop highlighted the importance of collaboration among regulators, designers, and operational teams within the nuclear industry, with case studies showcasing effective cross-disciplinary solutions. We would like to thank Rolls Royce for hosting the event and the WPC for organising the workshop.
