The turbogenerator №5 (TG-5) of the Kursk NPP power unit №3 has been disconnected by an electrical automatic equipment on April 15, 2015 at 05:42. The reason is being clarified. The power unit №3 capacity was reduced by 50%.

This event is pre-classified as "out of scale" in the International Nuclear Event Assessment Scale INES, so it is not essential for safety.

There are power units №№ 1, 3, 4 operating at the moment at the Kursk NPP. The power unit №2  has been in a planned overhaul since March 15 this year.

The radiation background is at level, corresponding to the normal operation of power units, and does not exceed natural background values, at the Kursk NPP and in the area of its location.

The Kursk NPP, as part of the «Rosenergoatom Concern», is included into the electricity division of the State Corporation "Rosatom". The station is located 40 km south-west of the city Kursk on the left bank of Seym. The NPP has four operating units with RBMK RBMK-1000 reactors with total capacity of 4 million KW of electricity. Power units were connected to the unified energy system of the country in 1976, 1979, 1983 and 1985. All existing power units had technical modernization in 1994-2009. The Kursk NPP is the largest power generating source in the Central Russian Chernozem.
