The break of spring
Spring has appeared on the ITER site, with green and yellow sprouting in the surrounding hills and along the platform's embankments — for Newsline, the perfect time to take a spring break.
We'll be back on 25 April to commemorate one of fusion history's watershed moments — Soviet physicist Igor Kurchatov's speech at the Atomic Energy Research Establishment in Harwell (UK) on 26 April 1956.
In the meantime work continues to progress on site, as the gallery below can attest. Workers are installing rebar at the second basement level (B1) on the east side of the Tokamak Complex; cladding work is nearly finished on the Assembly Hall; and concrete pouring for the cryoplant's underground structure almost complete.
Progress on the ITER site relies on finely tuned logistics. As concrete mixer trucks rush to the cryoplant worksite, every inch of ground surrounding the Tokamak Pit seems to be occupied by stacks of embedded plates, formwork equipment and steel rebar.
Underground structure completed
Work on the foundations and underground structures of the football-field-size ITER cryoplant is coming to an end. Soon, approximately four dozen concrete pillars (16 metres high) will be erected to support the building's steel structure. The objective is to install the first plant components at the end of the year.
Up another level
Rebar installation is progressing on plot #2 of the Tokamak Complex B1 level, at the right side of the photo. The completion of the B1 level will bring the Tokamak Complex flush with the ITER platform.
(More) men at work
The workforce concentrating on the Tokamak Complex is set to increase significantly in the next three months. Some 40 formworkers and close to 100 rebar specialists will be added to the teams presently working on the bioshield and the B1 level.
Concentric circles surround the space reserved for the ITER Tokamak where, for now, only the central crane stands. Including the machine, some 400,000 tonnes of concrete, metal and machinery will rest on the B1 basemat of the Tokamak Complex when construction and assembly works are brought to a close.
