The dome, which was installed in November 2014, forms part of the unit's double-walled containment structure - a major component for protecting the reactor and preventing the release of radioactive materials into the environment in the event of a serious accident. It is a key feature of the AES-2006 design.
Novovoronezh II is the lead project for the deployment of the AES-2006 design incorporating a Gidropress-designed pressurized water reactor, an evolutionary development from the VVER-1000. Construction of Novovoronezh II units 1 and 2 - also known as Novovoronezh 6 and 7 - began in June 2008 and July 2009, respectively.
The new Novovoronezh units will have a passive heat removal system that, in the event of loss of on-site power supply, will provide long-term heat removal from the reactor core to the atmosphere using natural circulation.
