The goal of this project is to carry out supporting calculations and software development large computations necessary for achieving the research goals of the ANITA project, funded by Energimyndiheten, industry and Uppsala University. These include large-scale molecular dynamics, TDDFT and DFT calculations to study the radiation damage in the materials targeted for small modular reactors. Moreover, the project will be used to carry out analysis of the results obtained from large scale simulations. We plan to carry out software development of the USER-EPH package (github.com/llnl/user-eph) to add new functionality into the model and to improve its performance. Finally, a portion of the resources will be used to support the doctoral thesis of an Uppsala University student.
