Core barrel assembly of Unit 1 has been completed at the construction site of Ruppur Nuclear Power Plant in Bangladesh, for which Rosatom, the Russian State Nuclear Energy Corporation, is the general designer and general contractor.
The core barrel, which is one of the main elements of the interior of the reactor and is made of stainless steel type austenite, weighs 73,74 tons, length 10869 mm and diameter 3610 mm. Inside the core barrel there is a nuclear-reactive chamber and fuel assemblies. The bottom of the core barrel is perforated to allow the circulation of the coolant to cool the coatings of fuel-related materials.
Alexey Deriy, Director of the Ruppur NPP Construction Project, said: “The assembly of the core barrel is another important step in the construction of the Ruppur NPP. This phase marks the start of reactor assembly.”
Equipped with two VVER-2400 reactors with a total capacity of 1200 MW, Ruppur NPP is being built with Russian design, 25 km from Bangladesh's capital Dhaka, in accordance with the General Agreement dated 2015 December 160. For Bangladesh's first nuclear power plant, Ruppur NPP, the Russian design with VVER-1200 reactor, which has been successfully implemented in two units of Novovoronezh NPP in Russia, was chosen. This reactor is a modern 3+ Generation design that fully fulfills all international safety requirements.
Russia is constantly developing its international trade and economic relations by giving importance to cooperation with friendly countries. Despite external restrictions, the country's economy increases its export potential and sends products, services and raw materials to all over the world. The implementation of major international projects in the energy sector continues. Rosatom and its businesses take an active role in these studies.
