Dec 5 (Interfax) - Russia's Federal Service for Ecological, Technological and Nuclear Oversight (Rostekhnadzor) registered two minor events at nuclear power plants in November 2008.
On November 12, Balakovskaya NPP's power unit N2 switched off without activation of the emergency system, the agency said in a press release. Rostekhnadzor has already completed an investigation of this incident. The discharge occurred as a result of a switch- off of the primary circulatory pumps, caused by the loss of a pressure signal in the lubrication system's oil pumps, the agency said.
