Izhorskiye zavody completes hydrostatic testing of VVER-1000 reactor vessel produced for Rostov NPP

Izhorskiye Zavody, part of OMZ Group, successfully completed hydrostatic testing of VVER-1000 reactor vessel produced for the fourth power unit of Rostov Nuclear Power Plant.

Hydrostatic test results were reviewed by a commission consisting of representatives of NIAEP (main contractor for plant construction project), Rostov NPP, OKB Gidropress, FSUE VO Safety and Izhorskiye Zavody specialists. In compliance with Programme and Methodology for Hydrostatic Testing the procedure was carried out on a special stand. Internal vessel pressure was set at a maximum of 24.5 MPa during the test.

Hydrostatic tests verified the durability of main metal components and seams of the reactor vessel.

Izhosrkiye Zavody specialists are currently preparing for control assembly of the reactor vessel and its internal components, which is one of the last stages of production process before the reactor is delivered to the customer.
