Izhorskiye Zavody successfully accomplished reactor vessel hydro-testing for the second Novovoronezh NPP-2 unit

Reactor vessel manufactured by Izhorskiye Zavody, part of OMZ Group, for the second Novovoronezh NPP-2 unit has successfully passed hydrostatic testing.
Results of the test were evaluated by expert commission consisting of representatives of OKB GIDROPRESS, FSUE VO Safety, JSC Atomenergoproekt, JSC Energoatom and Izhorskiye Zavody experts. Reactor vessel testing has been conducted on test stand in accordance with the Programme and methods for hydrostatic testing. Following the technology maximal pressure of 24.5 mPa was created in the reactor vessel in the course of hydro-testing.
Hydro-testing proved durability of the base metal and welded junctions of the product.
    At present experts of the enterprise prepare for check assembly of the reactor vessel internals and the cover of the upper unit which is one of the final stages in the manufacturing process of the reactor vessel before delivery to the customer. This year the equipment will be delivered to the construction site of the customer.
Contract on manufacturing and delivery of the equipment for Novovoronezh NPP-2 (NNPP-2) was signed in 2007. The deal includes manufacturing of two major equipment sets for NPP-2006 project reactor unit, particularly reactor vessels, steam generator vessels, vessel internals of overall weight more than 3500 tons.
Reactor unit VVER-1200 for NNPP-2 is the general installation of the NPP-2006 project and belongs to the most advanced III+ generation. In terms of the project NPP-2006 the manufacturing technology and construction of the VVER-1200 were improved to guarantee better security in compliance with the most demanding international standards, increase technical and economic characteristics and extend operating period of the power block to 60 years.
