Power unit №5 was stopped for scheduled preventive overhaul (SPO) and refueling in accordance with the application of the Novovoronezh NPP filed in an established order on July 11, 2015 at 00 hours.

Steam turbine №14 will be overhauled with the replacement of the condenser, average repair of steam turbine №13 will be done, full discharge of an active zone for conduction monitoring of reactor vessel will be made during the SPO. A number of modernization works will be also carried out.

Planned period of the SPO at the power unit №5 is 55 days.

The event does not affect safe operation of the nuclear power plant.

There are no violations of limits and conditions of safe operation at the Novovoronezh NPP.

The power units №3 and 4 operate at nominal power level in normal mode.

Construction and installation works on the power units №6 and 7 are carried out in a planned manner.

Average values of radiation background correspond to level of natural background values in the Central European Part of Russia in settlements of a 30-km zone round the Novovoronezhskaya nuclear power plant.

The Novovoronezhskaya nuclear power plant is a branch of the JSC "Concern Rosenergoatom". The station is located on the bank of the Don River in 42 km to the south of Voronezh. It is the Russia's first nuclear power plant with VVER reactors (water-to-water power reactors of case type with regular water under pressure). Each of five reactors of the station can be a main one – a prototype of serial power reactors: the power unit No. 1 with the VVER-210 reactor, the power unit No. 2 with the VVER-365 reactor, the No. 3, 4 power units with the VVER-440 reactors, the power unit No. 5 with the VVER-1000 reactor. The first power unit was launched in 1964, the second – in 1969, third – in 1971, fourth – 1972, fifth – 1979.

There are three power units (power units No.1, 2 were stopped in 1984 and 1990 respectively) in work at the moment.

Constructing of two innovative power units with capacity of 1200 MW № 6 and 7 is being done at the site of the Novovoronezh NPP.
