JSC "Atomenergomash" is the single-source manufacturer of equipment for the reactor system and the turbine island for all four units of the plant.
Hydraulic testing is one of the crucial inspection methods applied to pump housings during manufacture. It allows to confirm strength and tightness of the items. A committee confirmed that all four items passed the tests successfully. After that internal and external surfaces of the housings as well as all circumferential welds have been subjected to a dye-penetrant inspection.
Atommash has performed a key manufacturing stage of a set of Steam Generators for Unit No.2 of the “Rooppur” NPP
Atommash completed the installation of a set of Steam Generators for the Unit No.2 of the "Rooppur" NPP. Within 21 days, specialists installed 11 thousand coils inside each item. It had to be installed 105 horizontal rows. The next stage of manufacture includes welding of the heads. The equipment will be subjected to hydraulic tests and a whole range of control measures, including eddy current test of heat exchange tubes.
The advantage of Russian technologies was demonstrated to Ambassador Plenipotentiary of the People’s Republic of Bangladesh
“I visited “Atommash” last February, at that time the Minister of science and technology Yeafesh Osman and I saw blanks of the items. Today the equipment for the first Unit has arrived at Bangladesh, and here at the plant I saw not separate parts of the Steam Generators, but almost completed equipment. The purpose of our interaction is an implementation of all the rules and schedules, which, of course, will strengthen our cooperation and promote the development of the two countries", says Bangladesh Ambassador Extraordinary and Plenipotentiary in the Russian Federation Kamrul Ahsan.
During a visit to the shops the guests were able to get familiar with nuclear machine-building technology, witnessed the equipment manufacturing process, including the equipment manufactured for Rooppur NPP, namely: cladding of pipe blanks for main coolant pipeline, machining of pressurizer parts, manufacturing of reactor coolant pump spherical housings. “The main purpose of our visit was to see the process of manufacturing equipment for our nuclear plant at this factory, – the Ambassador Kamrul Ahsan said. – We have been able to see sophisticated and high precision equipment and therefore we do not worry about quality and safety of items manufactured here”.
The items will be shipped from Petrozavodsk to the sea port of Saint-Petersburg by road, to be then taken aboard. The cargo will be delivered by sea to the port of Mongla in Bangladesh. Further, the equipment will be transferred to a river vessel and shipped up the Padma River to a river terminal located at the Rooppur NPP construction site.
The last of the four Steam Generators was transported from the plant to the special birth, where three items with the total weight of more than 1000 tons, will be loaded onto a barge. The equipment will be transferred to Novorossiysk, then the item will be transported to the Republic of Bangladesh by sea. The sea route will be about 14 000 km. Thus, the main equipment of the Reactor facility for Unit No.1 of ROOPPUR NPP, has been shipped from the plant site.
Atommash has shipped the first Reactor Pressure Vessel for the first nuclear power plant under construction in the Republic of Turkey
The Atommash plant manufactured and shipped the Reactor Pressure Vessel for the first power unit of the "Akkuyu" nuclear power plant under construction. It took almost three years to manufacture the 330-ton Reactor pressure Vessel 12 meters long. A month earlier, four Steam Generators left the plant for the construction site of the "Akkuyu" NPP - the first nuclear power plant in Turkey. Thus, to date, the company has shipped all the most important large-sized equipment of the primary circuit of the reactor for the "Akkuyu" Unit No. 1. The production facilities of the Atommash plant allow manufacturing up to four sets of equipment per year.
Petrozavodsk Branch of JSC “AEM-technology” has successfully completed hydraulic tests of the first Reactor Coolant Pump (RCP) housing from the set of reactor coolant pumps housings intended for the first power unit of nuclear power plant Rooppur (the People's Republic of Bangladesh).Upon the pressure reduction, the visual inspection of the RCP housing is to be performed. The commission has confirmed that the first item passed the pressure tests successfully. After that, the outer and inner surfaces of the pump housing, as well as the circumferential weld joints are to be subjected to the repeated liquid penetrant testing.
Check assembly is a key operation during which assemblability of all manufactured internals and the reactor cover with the reactor vessel is checked.In the future, the check assembly will significantly reduce the time required for the installation of the reactor with internals at the site of the NPP under construction.
