A safety assessment has to demonstrate that the TBM with its own cooling system does not impede the safe operation of ITER under normal and accidental conditions. For analysis of the highly transient accident sequences, a RELAP5 model has been developed for the HCS and TBM system. The steady-state, In-Vessel LOCA, Ex-Vessel LOCA and In-Box LOCA have been analyzed and the designed TBM steady-state inlet/outlet temperatures have been obtained. In all LOCA accidents, the Ex-Vessel LOCA is the most dangerous accident because of the melting of the First Wall. Based on the results, the design of TBM could be modified further in order to improve the safety of TBM and ITER.展开更多
