The Kalininskaya NPP power unit №3 was unplugged by turbine protection technology on August 8, 2015 at 11 h. 44 min. Reactor installation of the power unit №3 is at 10% capacity. After elimination of causes the power unit will be plugged in. There are no violations of limits and conditions of safe operation.

According to the International Nuclear Event Scale INES, this event is estimated as "out of scale", so it is irrelevant to the security.

The power units №1,2,4 of the Kalininskaya NPP are operating normally.The radiation background corresponds to level of normal operation of power units, which doesn't exceed natural background values.

The Kalininskaya nuclear power plant is a branch of the JSC "Concern Rosenergoatom". The station is located in the north of the Tver region in the Udomelskiy area. There are four power units with water-cooled power reactors (VVER-1000) with installed capacity of 1000 MW each in the structure of the Kalininskaya nuclear power station.
