The second of the four hydraulic accumulators of the emergency core cooling system has been installed at elevation of +26.000.
Two cranes were used to perform the operation as the accumulator had to be brought into a vertical position and then installed at its proper location inside the reactor building of the second power unit of the LNPP under construction. The weight of the equipment assembled with a lifting device was approximately 90 tons.
