Chernobyl NPP: Another Success In Constructing the NSC

In total, three lifting operations will be performed for the East part of the Arch.

Metal structures of the Arch and the jacking system were completely inspected. The load of 100% was imposed on this system by lifting the Arch for 100 mm. Following that, operability of the jacking system was controlled and geodetic survey of position of the Arch’s metal structures and foundations was carried out.

The lifting operations are performed using 40 strand jacks, placed at 10 lifting towers. Each tower is 45 m high.

A great scope of preparatory works was implemented prior to the first lifting of the Arch. The area was cleaned-up from trees, bushes and construction debris, resulted from dismantling of buildings and structures. More than 57,733 m3 of technological materials and solid RAW was removed from the Shelter Object industrial site. The Arch’s foundations, lifting towers and the erection area’s platforms of 57,667 m2 in area were constructed.
