With a weight of approximately 36,200 tons, the shelter is about three times as heavy as the Eiffel Tower. At 165 meters long, 260 meters wide, and 110 meters tall, the arch could house the Statue of Liberty or the Notre Dame Cathedral. It provides a controlled and weatherproof environment where the solid radioactive remains of the destroyed unit can be held for the next 100 years. The New Safe Confinement replaces an old shelter that was installed as an emergency measure to contain the radioactive materials in the destroyed unit shortly after the disaster in 1986. The tracks of this system were installed at a 33-degree angle to optimize the load transfer onto the foundations. The skid shoes were completely synchronized on both sides of the structure to ensure a smooth and even operation. The innovative and award-winning skidding system is fully remote-controlled and consists of 116 skid shoes with an average capacity of 700 tons each. Mammoet skidded the arch from its construction site to the reactor building using a skidding system that has been specially designed for the project. Mammoet moved the New Safe Confinement at the request of Novarka – the joint venture responsible for the construction of the arch. The installation of the New Safe Confinement marks the successful conclusion of this highly prestigious construction project for Mammoet. The confinement is the largest land-based movable structure in the world. Clever engineering has helped install the arch-shaped construction over the destroyed reactor building. Mammoet finished skidding the New Safe Confinement over the reactor building of the Chernobyl Nuclear Power Plant in Ukraine.
