Izhora Branch, AEM-Technologies, JSC has carried out hydraulic tests of the pressurizer for Kudankulam NPP.
The pressurizer is part of the key equipment of the NPP reactor hall. The unit is designed to provide the necessary pressure in the primary circuit of the reactor. In the assembled condition, it is almost 14 m long and 3.3 m in diameter, the mass of the vessel is 187.5 t. Its internal volume is 79 cubic meters and the wall thickness is 152 mm.
During hydraulic tests, the vessel was subjected to tightness test at high temperatures. Water heated-up to 96 С was supplied to the pressurizer. At the same time, the pressure in the tank was increased to the maximum allowable value for this equipment, which is 24.7 MPa. The pressurizer has passed all the tests, retained the tightness and has been accepted by the commission. The equipment is being prepared for shipment.
Russia consistently develops international trade economic relations putting a focus on cooperation with friendly countries. Despite external restrictions, the domestic economy increases its export potential, delivers goods, services and raw materials around the world. Atomenergomash JSC actively participates in this work.
Kudankulam NPP is the largest nuclear power plant in India, it consists of six power units, two of which have already been put into operation. The NPP is being built within the terms of the intergovernmental agreement between the Russian Federation and India, signed in 1998. Russian VVER-1000 type reactors are used in the project. The facility is designed by Engineering Division of State Atomic Energy Corporation Rosatom. The capacity of each NPP power unit will be 1000 MW.
AEM-Technologies, JSC is the largest manufacturing company in the structure of Atomenergomash JSC, the machine-building division of State Atomic Energy Corporation Rosatom. Currently it is one of the leading Russian companies in the field of power engineering and the only Russian company with a full manufacturing cycle i.e. from its own production of a metallurgical blank to finished technologically advanced oversized products which can be shipped anywhere in the world. The structure of AEM-Technologies, JSC includes the following: an engineering center staffed by experienced designers and production engineers in St. Petersburg and four production Branches: Izhora and AEMSpecial Steels in St. Petersburg, Atommash in Volgodonsk and Petrozavodskmash in Petrozavodsk.
