Nuclear reactors

Manufacturing of water-cooled water-moderated power reactors is the key profile of AEM-Technologies. The high safety and reliability of the Russian-designed nuclear reactors allowed the company to take a leading position in the global nuclear energy market.

The current reactor generations combine the best developments in the industry and are in great demand among Russian and foreign customers.

General characteristics

AEM-Technologies produces water-cooled water-moderated power reactors VVER-1000, VVER-1200, and VVER-TOI. Each generation has individual advantages and the common key one is high reliability, which can be achieved through application of the up-to-date quality management methods, use of the unique equipment and constant development of technologies.

VVER-1000 is a time-proved and, today, most common reactor in the world. VVER-1200 is a flagship development with improved technical characteristics, higher power, and enhanced safety systems. VVER-TOI is the latest generation of Russian-designed reactors, a product with the best technical and economic parameters, targeted for promotion at the international market.
