ERF send date: Thu, 24-09-1992
ERF description: The short circuit occurred at 14:03 local time at 22 September 1991 in unit no. 6, while start-up tests of the generator were being carried out after annual outage. The short-circuit caused power to be cut off from units 6 and 5, which share a common electrical supply. An auxiliary power supply failed, but power to the safety systems was maintained by an emergency diesel generator. Repair work on the reserve system for electrical supply was started immediately. The event caused actuation of the reactor protection system.
The fire broke out at 5:20 local time at 23 Sept. 1992 in a transformer housing room. It was caused by a short circuit in the breakers of the reserve transformers of unit 6 and happened during during a transfer to the reserve power supply. Both units are now supplied by diesel generators and work is underway to create a temporary reserve power supply scheme.
