Fluid dynamics analysis of loss of vacuum accident of ITER cryostat

The main results indicated that the cryostat, even in the worst condition, seemed to withstand well LOVA without any relevant mechanical failure. The maximum pressure value resulted below the design limit pressure for the cryostat of 0.2 MPa for this accident. Finally it is worthy to remark that these results will be used for a further in depth evaluation of the structural performances of the cryostat itself.
