Fusion energy progress

摘要

The concrete basemat has been completed for the tokamak complex of the Iter fusion reactor project under construction at Cadarache in southern France. Iter said the 12-hour operation to pour concrete for the last of the 15 segments that make up the tokamak complex basemat -known as the B2 slab-was completed on 27 August 2014. The pouring started in December 2013. The B2 slab covers an area of 9,600m2 and comprises 14,000m~3 of concrete, 3,600 tonnes of rebar and 2,500 embedded plates. It will support some 400,000 tonnes of building and equipment, including the 23,000-tonne Iter tokamak.
