The Novovoronezh NPP: the power unit ?5 briefly stopped

On October 5, 2014 at 10:55 the power unit ?5 was stopped to fix the problem in the thermal mechanical equipment of one of the two turbine generators.

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

The event was not essential for security.

The rating on a scale INES is out of scale.

The power unit ?3 is operating normally, The power unit ?4 is in scheduled maintenance from 20 September 2014.

Construction and installation work at the power units ?6 and 7 are conducted as planned.

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

The Novovoronezhskaya nuclear power plant is a branch of 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 station is head – 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, No. No. 3, 4 power units with VVER-440 reactors, the power unit No. 5 with the VVER-1000 reactor. The first power unit was launched in 1964, the second – in the 1969, third – in the 1971, fourth – the 1972, fifth – 1979. There are three power units (power units (No No 1, 2 we're stopped in 1984 and 1990 years respectively) on work at the moment.
