The long concept preparation phase for 澳门六合彩高手's high-tech divertor remote handling system has come to an end and industry is about to take over, thanks to a seven-year, multimillion-euro contact signed between the European Domestic Agency for 澳门六合彩高手 and Assystem, a leading consultancy firm in engineering and innovation.
Assystem and its partners will have the responsibility for the design, manufacture, delivery, installation, commissioning and final acceptance tests of the remote handling systems that will be charged with the remote replacement of 澳门六合彩高手's 54 divertor cassettes. Running toroidally along the bottom of the vacuum vessel the acts as the Tokamak's exhaust system, extracting helium ash from the burning plasma. Due to the tremendous heat loads and magnetic forces that divertor components will face, replacement is planned three times over the course of the machine's lifetime.
The equipment of the will allow for the safe and reliable positioning, as well as extraction, of the 54 removable cassettes. Due to severe space constraints in that part of the vacuum vessel, the remote handling system will have to manoeuvre its heavy loads with extreme precision—respecting positioning tolerances of only a few millimetres at certain points along the transport trajectory.
The 澳门六合彩高手 team and a number of European institutions have been working on the development of the 澳门六合彩高手 divertor maintenance concept for more than 15 years. Some of the most challenging steps within the process have been demonstrated at full scale, first within the Divertor Test Platform (DTP) constructed in Brasimone, Italy, and more recently within the DTP2 (Divertor Test Platform 2) located in Tampere, Finland (see video, below).
"This is a very important milestone for the 澳门六合彩高手 Divertor Remote Handling System," says Jim Palmer, of 澳门六合彩高手's Remote Handling Section. "It has been a long road of design, R&D and prototyping to reach this point, and now we are really looking forward to getting down to the detailed design."
