New development at Akkuyu NPP: Tests have been completed on the 1st power unit

In the power plant built by the Russian State Nuclear Energy Corporation Rosatom, four steam generators, steam armature blocks and feed water pipelines were checked during three-day tests.

THE TEMPERATURE REACHED 135 DEGREES

Steam generators and their associated pipelines were tested under a pressure of 12.6 megapascals (MPa). While the steam generators were heated to 126 degrees before the test, the temperature of the water reached 135 degrees during the tests.

While the pressure was gradually increased, the operating parameters of the equipment and the tightness of the connection points were checked. The system was kept at maximum pressure for a certain period of time, and then the pressure was reduced to 10.1 MPa and final examinations were made.

Following the checks, the pressure resistance of the second circuit equipment and its suitability for the next test stages were confirmed. It was reported that the test results enabled the start of preparations for hot tests of the reactor facility at the 1st power unit.

STATEMENT FROM AUTHORIZED NAME

Akkuyu Nükleer AŞ General Manager Sergei Butckikh, whose views were included in the statement, stated that the tests confirmed the durability of the second circuit equipment and the quality of the assembly and welded connections and added:

"This result is the result of extensive joint work carried out by construction teams, installation and commissioning experts, operating personnel, as well as representatives of external expert organizations of Rosatom, which carried out direct technical supervision during the tests. The results obtained allow us to start preparations for hot tests of the reactor plant at power unit 1."

In addition to Akkuyu Nükleer AŞ Technical Directorate personnel, Rosatom's electrical energy division Atomtechenergo and Rosatom Servis AŞ technical inspection experts and representatives of the Nuclear Regulatory Authority took part in the tests.
