First major MAST Upgrade modules come together ahead of schedule | 01/06/2015
Another key step in the building of the MAST Upgrade fusion device was taken last week with the joining of the first two main segments of the new machine.
MAST Upgrade was designed to be divided up into seven modules to maximise the amount of assembly work that could be carried out at the same time. On Thursday 28 May, a day ahead of schedule, two modules were brought together for the first time. The 30-tonne MAST Upgrade vacuum vessel (known as the outer cylinder module) was lifted onto the lower cassette module, a key part of the Super-X divertor – the innovative plasma exhaust system that is a key feature of the new device.
This was the culmination of a huge amount of design, procurement and assembly effort by the MAST Upgrade team over the past 12 months. It means the project remains on track to hit its major build milestones over the coming months and deliver a machine ready for pump-down by October 2016.
Work package manager Richard Gowland said: “Bringing these two assemblies together has been one of the key build challenges for the MAST Upgrade project. The two needed to be brought together precisely as some of the gaps between them are only a couple of millimetres wide. This took a great deal of care both in the preparation and in the lift itself to prevent any clashes. Success was only possible due to the close collaboration between design, build and lifting teams including our contractors from Cavendish and Morsons.”
Head of CCFE Steve Cowley added: “This is wonderful progress by the team. We are starting to see the shape of our future machine.”
