How can the Chernobyl site be cleaned up in complete safety? Our team of engineers devised a prototype arch to confine, sort, store, and stockpile radioactive waste materials – while ensuring maximum protection for workers on site. The arch-shaped confinement structure designed to enable the dismantling of the old sarcophagus and the remains of the damaged reactor consists of a metal frame weighing 36,000 tonnes (fully equipped), measuring 105 metres in height and 150 metres in length, with a span of 257 metres. The structure is large enough to cover the Stade de France or the Statue of Liberty or the ground around the Eiffel Tower. The arch is as tall as a 30-storey building.

The International Thermonuclear Experimental Reactor (ITER) project, located in Cadarache, north of Aix-en-Provence in France, is designed to demonstrate the scientific and technical feasibility of fusion energy (the creation of energy by fusing two atoms).
The main building will house the world’s largest Tokamak reactor, a cylinder 28 metres in diameter and 29 metres high, weighing no less than 23,000 tonnes. Along with two adjoining ancillary buildings, the complex as a whole will be a reinforced concrete structure measuring 120 metres long, 80 metres wide, and 80 metres high. Other structures include an assembly building, a two-storey building, and various industrial buildings. The project also calls for large-scale nuclear doors (measuring 4 metres by 4 metres and weighing 40 tonnes) that are resistant to radiation and excessive pressure.
