Event Report Forms (ERFs) are filed to the IAEA. Sometimes there are multiple event reports, updating the rating, the event description. Here you only see the latest event report

ERF send date: Wed, 11-11-1992
ERF description: The plant was operating at rated power. At 9:24 a short circuit on the internal paging system tripped the inverter no. 6 which supplies power to the turbine electro-hydraulic (EH) control system. Drop of the EH fluid pressure caused turbine trip which scrammed the reactor. The cause of the short circuit was determined to be human error during maintenance of the paging system. All tge safety functions during the event were fully available. The inverter was repaired. A modification was done on the paging system to additionally isolate it from the inverter. After the system had been checked, the operation was resumed.
Basis for rating: real initiator - expected (reactor trip)
