TECHNICAL PROGRAM

The first day of the workshop will be dedicated to thermo-mechanical properties and irradiation effects. The second day will start with transport phenomena. A panel discussion on the implications of the modeling and simulations of materials for nuclear fuels and the impact on the fuel performance codes will conclude the workshop. The agenda for the workshop is given below and is also available as a pdf document.
