2016-02-04 - All of the B2 and B1 level works currently underway in the Tokamak Complex Seismic Pit rest on a unique foundation (the B2 slab), which is in turn supported by 493 seismic pads. When the building is completed and fully equipped, the B2 slab will support some 400,000 tonnes. In the very centre, workers are installing skirts, plates and reinforcement for the second level of the bioshield (the first level was completed on 20 January).
