An ICTP-IAEA Hybrid Meeting

Member States that benefit from the ongoing peaceful uses of nuclear technology need to safely dispose radioactive waste over a defined lifetime. To identify the preferred approach, the decision - making process should be underpinned by assessing the long-term durability of waste packages under storage or disposal conditions.  Underpinning the safety case are mathematical models that can predict the degradation of disposed waste packages considering the site-specific conditions, the type of waste form and waste package itself.

The non-commercial computer codes underpinning the science of degradation modelling of waste forms and waste packages are developed and understood only by a few researchers in this field. Unfortunately developing of such codes in lacking worldwide due to the lack of suitably trained scientists and engineers, national resource and lack of knowledge on the subject matter. This training school is focused on teaching the approach of degradation (durability) modelling of waste packages under storage or disposal conditions. There is a wide application for this modelling including the development of waste disposal concepts, radiological safety case and environmental impact assessment.

The International School on the  Degradation Modelling of Disposed Radioactive Waste forms will include the following topics:
  • Principles of ageing management of waste packages 
  • Degradation of waste packages,  waste form testing and durability determinations and environmental influences on these parameters
  • Establishing a conceptual degradation (durability) model
  • Hydrologic and geochemical information needed for modelling
  • Model application and objectives
  • Practical demonstration and exercises using modelling codes
  • Case study integration
