Hydraulic tests have been completed on the reactor pressure vessel for the first unit of the Akkuyu nuclear power station under construction in Turkey, Russian equipment manufacturer Atomenergomash said.
The tests on the 330-tonne RPV were carried out with a maximum pressure of 24.5 megapascals (MPa), which is about 1.4 times higher than operating pressure.
In a nuclear power plant, the RPV is the pressure vessel containing the nuclear reactor coolant, core shroud, and the reactor core.
