An ICTP-IAEA Hybrid Meeting
International Atomic Energy Agency (IAEA) are partnering with International Centre for Theoretical Physics (ICTP) to deliver a Hybrid Training School the principles and the modelling approaches for radionuclide migration in the geosphere.
Nuclear energy is a reliable solution to the challenges posed both by a finite energy supply from fossil fuels and from climate change. All Member States that benefit from the on-going peaceful uses of nuclear technology need to safely manage radioactive waste. In addition, many Member States are tasked with the safe management of waste and environmental contamination resulting from past practices or events. To identify the preferred approach, the decision making process should be underpinned assessments of the long-term impact of the various waste management and/or remediation options. Underpinning the assessments are mathematical models that can predict the potential movement of contaminants within the environment.
Predicting the fate and transport of contaminants in a subsurface environment is essential to the disposal of waste and the evaluation and remediation of soil and groundwater pollution. This training school is focused on teaching the approach to modelling contaminant fate and transport in groundwater. There is a wide application for this modelling including the development of waste disposal concepts, radiological safety case, environmental impact assessment and remediation for contaminated land.
The International School on the Physical Basis for Radionuclide Migration (storage, disposal and contaminated sites) will include the following topics:
Establishing a conceptual site model
Basics of radionuclide behavior in the environment
Hydrologic, geochemical and conceptional information needed for modelling of radionuclide migration
Mechanisms of colloid-facilitated transport of radionuclides by groundwater
Model application and objectives
Analytical and numerical model approaches
An overview of geochemical and biosphere modelling
Managing modelling uncertainties
Hands on experience with modelling codes (software applications)
1D and 2D models used for radionuclide migration (e.g. Amber, Phreeqc, Minqa2, etc.)
Advanced radionuclide migration models used for transport in different environments
Case study integration, including
Radionuclide speciation in leachate solution
URL migration investigation
Colloidal fractions of radionuclides from leaching of glass- and cement-based Matrices
Modelling approaches for colloid-facilitated transport of radionuclides in groundwater

Requirements for interactive practical sessions: Basic knowledge of the theory of water movement, solute transport and heat transport is recommended. Personal laptop computer would be required.
Grants: A limited number of grants are available to support the attendance of selected participants, with priority given to participants from developing countries. There is no registration fee.
The deadline on 30 September 2022 is for participants needing financial support and/or visa, the deadline on 21 October 2022 is for online participation.
