MECHANICAL STRENGTH OF THE FIRST WALL BOX OF NET LOADED BY ACCIDENTAL INTERNAL PRESSURE
The structural analysis of a first wall box design proposed for NET (Next European Torus) was performed assuming the accidental loads due to a coolant pipe break in a breeding blanket module and the consequent failure of the module shell. The pressure transient has been determined from the reaction kinetics of the breeder- water interaction. Finite-element analysis in both the elastic and the elastic-plastic regime was carried out on a single shell structure equivalent to the real structure of the box. The first wall failure is reached for an overpressure of about 0.15 MPa. The time for mitigating counter measures is about two hours.
