The equipment was installed through the open top of the cylindrical part of the reactor building using a heavy-duty crawler crane.
A total of four ECCS hydraulic accumulators will be installed, each of which represents a vertical cylindrical high-pressure vessel made of high-strength steel.
Weight of one accumulator — 80 t, diameter — 3.2 m, volume — 60 cubic meters.
Installation of hydraulic equipment is one of the most important activities bringing power unit 2 closer to the key milestone — welding of the main circulation pipeline.
All works at the Akkuyu NPP construction site are carefully monitored by independent inspection organizations and the national regulator, the Turkish Nuclear Regulatory Authority (NDK).
