An International School on the of Nuclear Waste Vitrification was held at the International Center for Theoretical Physics (Trieste, Italy) on September 23-27, 2019. The event was organized with the support of the International Atomic Energy Agency and the International Center for Theoretical Physics.
The purpose of the School was to discuss current issues and challenges facing nuclear power and to address the research on vitreous radioactive waste. The School helped participants to better understand the process of vitrification and to familiarize themselves with the set of methods available for the study of the exclusion of nuclear and radioactive waste.
The program of this event was divided into 5 main topics:
- Fundamentals of immobilization of nuclear waste in glassy materials and modeling of nuclear glass structure;
- Technological approaches of nuclear waste vitrification;
- Chemical durability of glass waste forms and long-term performance modeling;
- Interaction of vitreous storage with geological environment and modeling of aging processes;
- Effects of radiation damage in vitreous forms (including modeling).
The youth participating in the School had the opportunity to present their work or the work of groups on this topic. Serhii Kupriianchuk, the researcher of the ISP NPP of the NAS of Ukraine, the junior researcher of Decommissioning Department represented Ukraine at the School. He made a presentation on “Properties of fuel-containing materials and their localization in the Shelter”.
Participation in the School promotes further international cooperation in the field of nuclear waste vitrification.
