While Bangladesh is expecting its first megawatts of nuclear energy in the coming years, manufacture of various machineries and equipment is running in full swing in Russia. Some of them have already reached Bangladesh, some have been shipped and others are still in manufacturing process.
Lower semi-vessel of the Reactor Pressure Vessel (RPV) of Unit 1 has been assembled at the Volgodonsk Branch of AEM-technology under Atommash. The company is a part of Engineering Division of Rosatom – Atomenergomash.
Head and shells of the reactor core were assembled for subsequent welding of joints and heat treatment of joint welds. Following completion of the process the lower semi-vessel will undergo different inspection operations. Then it will be jointed to the already manufactured upper semi-vessel.
The Reactor represents a vertical cylindrical body with elliptic bottom with the Core and other equipment inside it. In the upper part of the vessel there are nozzles for coolant supply and removal, and also nozzles for emergency coolant supply in case of circuit depressurization.
