Atommash, part of the Atomenergomash engineering division of Russian state nuclear corporation Rosatom, has completed the core barrel of the reactor vessel for unit 1 of the Rooppur Nuclear Power Plant (NPP) in Bangladesh.
In a statement on Saturday, Rosatom, the Russian contractor of Rooppur Nuclear Power Plant, said the manufacture of reactor pressure vessel (RPV) for unit-1 of 2400MW plant has recorded further development as the production of the shroud has been completed at the Volgodonsk Branch of AEM-technology.
The core barrel is one of the three main elements of the RPV Internals, said Rosatom.
The equipment, a key part of the reactor internals, consists of six shells and an elliptical bottom. It is about 11 metres high and weighs 63 tonnes.
Core barrel itself is 11metre high and 63 tons in weight and consists of six shells. At the upper part of the Core Barrel, there are 238 holes of 196mm diameter and two holes of 300mm diameter.
The holes are arranged in six rows along the perimeter of the Shell and intended for coolant exit.
There are also 1,344 holes with different diameters at the bottom. These are for the installation of supports and to protect the fuel assemblies from mechanical particles entering them.
Atomenergomash is the sole supplier of all reactor equipment for the Rooppur plant, which is under construction on the eastern bank of the river Padma and which will consist of two 1200MW power units.
