Installation of eight heat exchangers of passive heat removal system (PHRS) has been completed at Unit 1 of Rooppur NPP (general designer and general contractor is Rosatom State Corporation engineering Division). Each heat exchanger is a metal structure weighing over 32 tons, 8530 сentimeters long, 5904 сentimeters wide. The installation was performed at elevation +38.100.
PHRS is a passive safety system required for ensuring long-term removal of heat from the reactor core into the atmosphere in the absence of all power supply sources.
“When the system is operational, atmospheric air enters the PHRS heat exchanger which cools it down at one side, while the steam from the steam generator condenses inside the heat exchanging tubes”, explained Alexey Deriy, Vice President of ASE JSC – Director for Rooppur NPP Construction Project.
Rooppur NPP with two VVER-1200 reactors with the total capacity of 2400 MW is being constructed under the Russian design, 160 km from Dhaka, the capital of Bangladesh, in accordance with the general contract dated December 25, 2015. The Russian design with VVER-1200 reactors has been selected for the first NPP in Bangladesh. The design has been successfully implemented in two power units of Novovoronezh NPP. This is an evolutionary design of III+ generation, which is fully compliant with the international safety requirements.
Russia is consistently developing international trade and economic relations, focusing on cooperation with friendly countries. Despite external restrictions, the domestic economy is augmenting its export potential to supply goods, services and raw materials all over the world.

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.
