2015-07-10 - Early one summer morning, the light begins to illuminate the Tokamak Pit where approximately 150 workers are active. From 400 today, the number of workers on the platform will reach 1,000 by the end of the year.

2015-07-10 - The walls between the massive columns will host the "lower pipe chase" and be made of special, high-density concrete (3.9 tonnes per cubic metre as compared to 2.5 tonnes for regular concrete). Fabricating the concrete in an on-site facility will require 6,000 tonnes of magnetite gravel that will be shipped from Kiruna, in Swedish Lapland.
