In the reactor compartment of the Rooppur NPP power unit 2 (with the Rosatom State Corporation Engineering Division being the general designer and general contractor), installation of the emergency core cooling system (ECCS) has been completed by specialists of the Energospetsmontazh JSC Branch (being part of the Rosatom Engineering Division) in the People's Republic of Bangladesh.
“All four ECCS tanks being installed in their regular places suppose a large-scale and labor-consuming process that requires the specialists’ operational excellence,” said Alexei Deriy, JSC ASE Vice President, Director of the Rooppur NPP construction project. “The hydraulic tank is a vertically-located high-pressure vessel. The weight of each of them is about 80 tons, and the volume is 60 cubic metres. By the way, this volume would be enough to fill 20 tanks of fire vehicles in average,” he went on to say.
The emergency core cooling system consists of the passive and active parts. The hydraulic tanks are passive NPP safety systems that are operated without personnel or use of the external power supply sources. During the operation of the power unit, these tanks accumulate an aqueous solution of boric acid (neutron absorber), intended for emergency flooding of the reactor core in loss-of-coolant accidents, in order to prevent damage to the fuel elements and fuel melt.
Rooppur NPP equipped with two VVER-1200 reactors of the total 2400 MW capacity is being constructed under the Russian design160 km from Dhaka, the capital of Bangladesh, in accordance with General Contract dated December 25, 2015. The Russian design with VVER-1200 reactors was selected for the first NPP in Bangladesh, which was successfully implemented at two units of the Novovoronezh NPP. This is an evolutionary Generation III+ design which fully complies with all the international safety requirements.
For reference:
Rosatom State Corporation Engineering Division unites the leading companies of the nuclear industry, namely: Atomstroyexport JSC (Moscow, Nizhny Novgorod, branches in Russia and abroad), Joint Design Institute - Atomenergoproekt JSC (Moscow, Nizhny Novgorod, St. Petersburg branches - design institutes, branches in Russia and abroad, R&D branches) and subsidiary construction organizations.
The Engineering Division ranks first in the world by the order portfolio and the number of NPPs constructed simultaneously across the world.
About 80% of the Division’s revenues originate from foreign projects.
The Engineering Division implements construction projects for high-power NPPs in Russia and across the world, renders a full range of EPC, EP, EPC(M) services including project management and design activities, and develops Multi-D technologies for the management of complex engineering facilities. The Division relies on the achievements of the Russian nuclear industry and innovative state-of-the-art technologies.
We construct reliable and safe NPPs with Gen III+ VVER reactors that are in line with all international requirements and recommendations.
