Activity on every floor
20 Feb 2017
At every floor of the Tokamak Complex—from the lowest underground level (B2) all the way to the second regular level of the bioshield (L2)—there is intense activity.
Civil works at Tokamak Building basement levels B2 and B1 are now fully complete and finishing works have started. Just overhead, flush with the level of the construction platform, three out of the nine plots for the L1 basemat have been poured.
At the centre of this photo taken last Thursday, as night descended, the first of 18 embedded plates are clearly visible. Anchored in the massive columns at L2 level, these 4.5-tonne plates will support the brackets of a temporary in-pit tool, necessary during the assembly of the vacuum vessel sectors. In one month, work is scheduled to start at the L3 level of the bioshield.
Work is progressing rapidly on the less complex Diagnostics Building, to the right of the image, where civil works have been completed up to L1 level and reinforcement is underway for the L2 concrete slab.
The B1-level walls of the Tritium Building, at the opposite end of the Tokamak Complex, are nearly complete and the installation of L1 formwork is imminent.
Finally, the steel structure has been erected for the Radio Frequency Heating Building adjacent to the Assembly Hall. Two concrete slabs are planned to create the three storeys of the building.
