Role in the project

The main contribution of GRS is in WP3 to the final design of the SACO for the PKL test facility, initial pre-test calculations with AC² (ATHLET) to define boundary and test conditions and contribute to the numerical analyses and the code benchmark. Furthermore, GRS contributes to WP4 with a report on the pre- and post-test calculation of one test at the PASI facility with AC². As developer of the AC² code and due to its continuous involvement in the PKL project with pre- and post-test calculation, GRS is uniquely placed to support FRA-G in the final design of the SACO for the PKL test facility and the definition of boundary and initial conditions.
