Implementation of the full-scale prototype pipe option design into non-standard first wall panel

•Pressure drop for long, short regular and irregular FW fingers are 81,6; 70,7 and 694 kPa respectively.•Coolant temperature rise for Inductive I mode is 30 °C and 52 °C for peak heat flux.•There is an overheating of beryllium armor, on less than 5% of beryllium tiles.•The safety margin to CHF is 5,3 under peak heat flux.•Acquired pressure drops will be used to select hydraulic imitators for FW beam analysis.
