The Novovoronezh nuclear power station is a nuclear power station close to Novovoronezh in Voronezh Oblast, central Russia. The site was vital to the development of the VVER design; every unit built was essentially a prototype of its design. On this site is built the Novovoronezh Nuclear Power Plant II.

In 2010 Novovoronezh-5 was shut down for modernization to extend its operating life for an additional 30 years, the first VVER-1000 to undergo such an operating life extension. The works include the modernization of management, protection and emergency systems, and improvement of security and radiation safety systems.

The Novovoronezh Nuclear Power Plant has five units:

Unit	Reactortype	Net capacity	Gross capacity	Commercial Operation	Shutdown
Novovoronezh-1	VVER-210 (prototype)	197 MW	210 MW	31.12.1964	16.02.1988
Novovoronezh-2	VVER-365 (prototype)	336 MW	365 MW	14.04.1970	29.08.1990
Novovoronezh - 3	VVER-440/179	385 MW	417 MW	29.06.1972	2016 planned
Novovoronezh-4	VVER-440/179	385 MW	417 MW	24.03.1973	2017 planned
Novovoronezh-5	VVER-1000/187 (Prototype)	950 MW	1000 MW	20.02.1981	life-extended in 2010
