General Methodology of Safety Analysis and Evaluation for Fusion Energy System (GEMSAFE) was applied to the International Thermonuclear Experimental Reactor (ITER) interim design in the Engineering Design Activities (EDA) stage to identify the candidates of the Design Basis Events (DBEs) stage. These DBEs were compared with those of the ITER design in the Conceptual Design Activities (EDA). As a result, 18 candidates of DBEs Were selected for EDA interim design in comparison with 25 DBE candidates for the CDA design. The DBE candidates related to the fuel area were categorized in higher event categories than those of the CDA design due to the increase of the mobile tritium-contained in some components. It is important to reduce the inventory of the tritium absorbed in the dust in the vacuum area as well as in the CDA design. Measures were recommended to reduce the mobile tritium dissolved in the coolant in the single loop due to the increase of this estimated inventory.
