The SOTERIA project ("Safe Long Term Operation of Light Water Reactors Based on Improved Understanding of Radiation Effects in Nuclear Structural Materials") is a four-year European project that started on 1st of september 2015 under the auspices of EURATOM in Horizon 2020. The main objective of the project is to improve understanding the aging phenomena of steels used in the manufacture of reactor vessels and its internal components. Through research in the field of aging steel, this regulator and the operator will be provided with the key information that is necessary for the safe and long-term operation of existing European nuclear power plants. The project involves a number of European research centers (including the JSI) as well as industry partners. The project is coordinated by CEA, France.

On the workshop, the results of the last four years in the form of lectures and posters were presented. IJS is involved in the development of a crystal plasticity model for the mechanical description of neutron-irradiated stainless steels, as well as in the modeling of intercrystalline boundaries to simulate the occurrence of early damage or damage. cracks. At the workshop, IJS, in collaboration with the IRSN, CNRS and CEA, presented a comparison of crystal plasticity methods based on finite element and fast Fourier transforms used in simulations of irradiated stainless steel. The study was presented in the form of a poster entitled "Spatial discretization convergence analysis of CP-FEM and CP-FFT models employed for neutron-irradiated austenitic stainless steel."

The workshop organized by TECNATOM in Miraflores de la Sierra was attended by dr. Oriol Costa and Samir El Shawish from the Reactor Engineering Division of the Joseph Stefan Institute.
