ROSATOM has announced installation of the outer shell of the containment building dome at unit 2 of the Novovoronezh II nuclear power plant.
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.
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.
