Works on assembling the three-dimensional block, which will cover the accident opening in the roof and wall of Chernobyl NPP Unit 4 Turbine Hall, are in progress within the Shelter Object Local Zone. The structure assembling is scheduled for completion in March 01, 2014.
Previously within the frame of Project “Recovering of the Containment of ChNPP Unit 4 Turbine Hall between axes 46-52 and A-B” the accident haydite concrete wall panels and connecting structures between columns were removed, as well as the upper damaged panels were reinforced. After that the shields were assembled and installed at the areas of dismantled panels along axis A. A total area, at which the shields were installed, is 216 square metres.
All works under the project are implemented by Ukrtransbud Corporation in cooperation with the Chernobyl NPP organizational units.
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.
Two commissions on investigating the causes of the event were working at the ChNPP through February 13-20. They analyzed the situation that led to the destruction of building structures, and proposed measures to eliminate the consequences.
The works are implemented within the frame of Project “Recovering of the Containment of ChNPP Unit 4 Turbine Hall between axes 46-52 and A-B” developed by Kyiv Institute “Energoproekt” and approved by the SSE ChNPP Order in September 2013.
A contract on performing the construction and erection activities was concluded with Ukrtransbud Corporation in November 2013 based on competitive bidding.
