The extension is required to lift the reactor building dome on the second LNPP-2 power unit under construction.
The works were performed in two shifts. First, the boom of the crane was placed at the special site. Then it was extended with the 12-meter segment which weighs more than 9 tons. The structure of the load lifting mechanism allows to perform such modifications of the crane without any auxiliary equipment.
The inner containment dome will be installed at the elevation of over 50 meters. Once it is in place, the height of the reactor building will exceed 65 meters.
