Association EURATOM-CEA EFDA Goal Oriented Training Program Port Plug Engineering TORE SUPRA Ø Objectives üBackground Cause = nuclear fusion reactions for long term Þ high magnetic fields Þ produces high energy neutron Þ generates very high temperatures Consequence = maintenance in nuclear environment Þ make first wall components highly constrained and causes its wear Þ many parts of this region must be replaced or refurbished during the reactor’s life Þ maintenance of a reactor in exploitation is a critical point, because it directly affects the availability of the machine and its economical productivity üProgram motivations § Even if the goal of ITER is not to be an industrial reactor, it is essential to consider its maintainability for at least two major reasons: Þ To have powerful available experimental equipment Þ To demonstrate that the maintenance by remote handling is possible for the further steps (DEMO) § Because remote handling is one of the most important technical issues of the whole project 2 nd GOTA-PPE meeting Julien WAGREZ 06 December 2009 3

Association EURATOM-CEA TBM -TG 04 Kick off Meeting Task 19 : Design and development plan of the port cell dis-/assembly RH system TORE SUPRA Ø Remaining work and outlook ü First test with one dexterous industrial robot arm have been performed for cutting accessibility ü A more realistic cutting tool coming from HAS work is about to be integrated in order to replace the current simplified shape ü The remote removal of the insulation “half-shells” is about to start ü Other industrial robotic arms will be implemented in order to check the feasibility with different kind of robot providers. This is in order to avoid any exclusive robotic arm architecture and provider. ü An important handling equipment is required to transport the pipe forest during maintenance operations. A first assessment of this tool is starting. ü A preliminary design of the bio-shield will specify it’s main interfaces 2 nd GOTA-PPE meeting Julien WAGREZ 06 December 2009 19
