Quintessa recently ran a one-week residential course in Performance Assessment (PA) for UKAEA technical and project management staff from Dounreay and Harwell sites.
The course, which drew on IAEA training material, focused on the use of PA to determine short- and long-term safety and environmental impacts from radioactive waste disposal, contaminated land and authorised radioactive discharges.
The workshop demonstrated the structured and systematic approach to PA through lectures and practical exercises. Topics included the definition of scenarios, the development of models (for the source-term, geosphere and biosphere), analysis of results, confidence building activities, and the broader use of PA studies in safety cases.
