In June 2023, Quintessa provided a week-long in-person tailored AMBER training course to two Assystem (BU C2D - Cycle, Dismantling, Defence) employees.
The course covered the fundamental principles of safety cases and safety assessment methodology. Sessions then covered the conceptual and mathematical representation of a radioactive waste disposal system (near-field, geosphere and biosphere), transport pathways (groundwater, gas, human intrusion) and human exposure, as well as building confidence and the management of uncertainties. These sessions covered both theoretical aspects and practical implementation in AMBER. The participants used the knowledge and advice provided to build an AMBER model of a radioactive waste disposal system, selected by Assystem, during the week, with the close support of Louise Bruffell.
Training excerpt. Conceptual model: The evolution of cementitious materials and the impact of pH in the system.
Training excerpt. AMBER implementation: The impact of stages of cementitious material degradation on the sorption coefficients of the contaminants, due to the change in pH of the system.
