Atommash, which is part of Atomenergomash, the mechanical engineering division of Russian state atomic corporation Rosatom, performed the fit up and welding of set of steam generators for Unit 1 of Rooppur NPP in Bangladesh, Rosatom said in a press release on 5 March.
Steam Generator is a heat exchanger, it is part of a reactor plant and belongs to products of the first safety class. The diameter is more than 4 metres, the length of the apparatus is about 15 metres, weight – 340 tonnes, Rosatom explained, adding that the equipment of one nuclear power unit includes four steam generators.
Previously, the vessel of the steam generator was assembled from four shells and welded together. In the welding process, more than 2,000 kilograms of flux and more than 12,000 metres of wire were used in total.
Currently the first steam generator vessel weighing up to 160 tonnes is finishing the machining process, Rosatom said. Within a month, the item will be ready for installation of primary circuit header. The other three heat exchanger vessels are on different stages of production: machining, inspection performance.
