GRS is a founding member of the European TSO network (ETSON), and a member of NUGENIA and ESReDA. Via GRS’ subsidiary RISKAUDIT, jointly owned with IRSN, GRS’ experts support several international regulatory authorities and TSOs in projects financed by the European Commission or other international institutions.
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.
