Query: Analysis of an in-service rupture of the Inner First Wall of Tore Supra   The last experimental campaign of Tore Supra was also the last one with a set
of plasma facing components mainly dating from the assembly of the machine in
1988. This campaign was interrupted a few days ahead of schedule because of the
rupture of one coolant tube of the Inner First Wall (IFW). The rupture was
observed by an abrupt increase of the pressure in the vessel. It was caused by
a water leak which occurred two seconds after the end of the lower hybrid
heating pulse during the current ramp-down. Investigations show that the
accident is not related to the operation of the machine or a weaker element but
rather to a localised heat flux exceeding the heat removal capability of the
IFW.
