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

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.

Rostov NPP is a branch of Rosenergoatom Concern OJSC. The nuclear power plant is located on the bank of the Tsimlyansk Reservoir in 13.5 km from the city of Volgodonsk. Two power units are currently operated at the plant. Power unit 1 was put into operation in 2001; power unit 2 was launched in December, 2010. Construction of units 3 and 4 is currently underway.

Last year Izhorskiye Zavody delivered equipment for third power unit to Rostov NPP. Izhorskiye Zavody is currently completing production of reactor equipment for the power unit 4, including reactor vessel with internal components and upper unit lid, as well as supporting and retaining rings and accumulators.
