Works on pre-assembling of a heavy lift crane were commenced within the frame of the project on recovering the containment of Unit 4 Turbine Hall. A three-dimensional block of the Turbine Hall roof will be installed into the design position by this crane.

For this purpose the construction site was prepared and crane runways were assembled within the Shelter Object Local Zone. Works on assembling the metal structures of the three-dimensional block of the Turbine Hall roof (without profiled sheeting), by which the accident opening in the roof and wall of Chernobyl NPP Unit 4 Turbine Hall will be closed, also were completed.

Restoration of the destroyed section of the roof and zones of wall panels’ collapse will result in recovery of ChNPP Unit 4 Turbine Hall confinement integrity that is the part of the Shelter Object contained facility.

For your reference. A partial collapse of wall panels and a section of Unit 4 Turbine Hall light roof occurred on February 12, 2013. The destruction area equaled about 600 m2.
The works on recovering the containment of Unit 4 Turbine Hall are implemented within the frame of the project developed by Kyiv Institute Energoproject. The construction and erection activities at the site are performed by Ukrtransbud Corporation.
