Russia’s state nuclear corporation Rosatom has completed cold hydraulic testing of the primary coolant circuit at Turkey’s Akkuyu-1 nuclear power plant under construction in the southern province of Mersin, a statement said.

Rosatom said that during the tests, pressure in the circuit was increased to 24.5 megapascals (MPa), approximately 50% above the reactor’s normal operating pressure of about 16 MPa.
