Dhaka, April 20,  2021 (PR) - The Volgodonsk Branch of AEM-technology has started shipping the equipment of the reactor plant. The customer will receive the vessel for the VVER-1200 nuclear reactor and the first two steam generators for the second power unit of Rooppur Nuclear Power Plant (RNPP) under construction in Bangladesh.

 

The nuclear reactor was manufactured for two years, the manufacturing process includes 768 operations, including 143 control points. The plant's specialists carried out the whole range of testing, including hydraulic test of the vessel with the standard cover of the upper unit. During the test, the maximum pressure (24.5 MPa), which is 1.4 times higher than the operating pressure, was created inside the reactor.

 

The final stage of the equipment manufacturing is test assembly with the internals. The core barrel, core baffle, and the protective tube unit were installed into the reactor vessel in the design position. The plant's specialists, together with the customer's representatives, performed the necessary inspection operations. As a result, all geometric parameters, alignment of the components were checked and the quality of the manufactured item was confirmed.

 

The reactor weighing 320 tonnes, 12 meters long, and two 340-ton steam generators, 14 meters long, will be brought to the plant's special berth and loaded onto a barge. The equipment will be delivered to Novorossiysk by water, then the item will be sent to the Republic of Bangladesh by sea. The sea route will be about 14,000 km.

 

Director General of JSC AEM-technology Igor Kotov, commenting on the shipment, noted: “RNPP is the first nuclear facility for Bangladesh, and in the process of work we were very attentive to any questions and requests from our Bengalese partners. It is thanks to the trust and effective interaction with the customers that today, in strict compliance with all the contractual obligations, we are shipping the key equipment for the second unit of the RNPP. To date, this is the last shipment of such a volume for Bangladesh, but I am sure that our fruitful cooperation with the representatives of the Republic, which is taking the first steps in the nuclear power industry, will continue in one form or another.”

 

Reactor plant manufacturing is a unique high-tech competence that only a few countries in the world possess. JSC "AEM-technology" is the only company in Russia that manufactures a complete set of the NPP nuclear steam generating plant (NSGP). The production facilities of Atommash allow manufacturing up to 4 sets of the equipment per year. It is worth reminding that for two power units of the nuclear power plant in the Republic of Bangladesh, JSC AEM-technology has manufactured over 50 types of equipment: reactor pressure vessels, upper unit, core barrel, core baffle, protective tube unit, sets of steam generators, reactor coolant pipelines, reactor coolant pumps and other equipment. In total, over 4,000 tonnes of equipment will be shipped.

 

The reactor is a vertical cylindrical body with an elliptical bottom, inside which the core and internals are located. From above, the reactor is hermetically sealed with the cover with the drives of mechanisms and reactor control and protection rods installed on it and the nozzles for leading out cables of the in-core instrumentation detectors. The cover is fastened to the vessel with the studs. In the upper part of the vessel, there are nozzles for supplying and removing the coolant, as well as the nozzles for emergency supply of the coolant.

 

RNPP is designed and being constructed according to the Russian project. The design and construction of the facility is performed by the Engineering Division of the State Atomic Energy Corporation Rosatom. The power plant will consist of two power units with the VVER-1200 reactors, the life cycle of which is 60 years with the possibility of extending the service life for another 20 years.
