SCK•CEN Academy short course on underlying R&D for the disposal of radioactive waste

March 19 - 20, 2014   Mol (BELGIUM)

Integrated performance and safety assessment of a candidate surface disposal site:
- Methodology of safety assessment (based on ISAM), analysis of Features, Events, and Processes (FEPs) and development of scenarios for long-term performance and safety assessment;
- Development of conceptual and numerical models for evaluating the safety of near surface disposal;
- Basic principles of water flow, radionuclide transport, and heat flow in saturated or unsaturated media: processes and data;
- Deterministic consequence analysis for the groundwater pathway by integrating calculations from near field, geosphere, and biosphere models;
- Analysis of human intrusion scenarios;
- Issues of chemical toxicity for non-radiological waste components;
- Role of geochemistry in process understanding and modelling;
- Confidence building: Model verification and model benchmarking.

Selection and characterization of a geological disposal site:
- How to find a suitable geological environment now and for the long-term future;
- Boom clay in the Campine underground as the reference host formation.

Radionuclide geochemistry and its effect on radionuclide migration:
- Why is the radionuclide geochemistry important?
- What do we need to know?
- How can we determine these characteristics?
- Can we interpret? Discussion of examples.
