AEM technologies supplies pressurizer for Kudankulam Nuclear project

11 Apr 2023 CW Team

According to a statement from Rosatom, the pressurizer is referred to as the major circuit equipment of the VVER reactor and is in charge of creating and maintaining pressure and coolant volume.

During the operation of a nuclear reactor, it is utilized to restrict pressure variations in transient and emergency modes. 187.5 tons are the weight of the apparatus. It measures roughly 14 meters long and 3.3 meters in diameter when assembled. Its volume is 79 cubic meters, and its walls are 152 millimeters thick.

The apparatus passed a tightness test at high temperatures and the maximum permitted pressure of 24.7 MPa during the hydraulic test. On April 3, 2023, the customer received the package. Around 17,000 kilometers will need to be traveled by the pressurizer to reach its destination.

The Kudankulam nuclear power plant, which is located in Tamil Nadu in southern India, is planned to have 6 Power Units with 6000 MW of installed VVER-1000-type reactor capacity. Units No. 1 and No. 2 from the initial phase were added to India's national energy grid in 2013 and 2016, respectively. Power Units Nos. 3, 4, and 5, which represent the second and third phases of the Kudankulam NPP, are now being built.

The State Atomic Energy Company Rosatom's machine-building business Atomenergomash has AEM-Technologies as its largest production company. It is one of the top Russian companies in the nuclear power engineering industry and the only one in the country with a full manufacturing cycle, starting with its own production of a metallurgical blank and ending with finished, large-scale high-tech products that can be shipped anywhere in the world.

AEM-Technologies incorporates an engineering center in Saint Petersburg, staffed with experienced designers and process engineers and four production sites.
