Incidents

* In 2006 when Unit 3 was taken offline for routine refueling, it was discovered that an electrical wire had not been plugged in correctly during the last outage in 2005. This ranked Level-1 on the INES Scale, the lowest level on the 7-point scale * In 2007, the plant experienced four separate events that qualified as Level-1 on the INES Scale. * In August 2009, during the annual exchange of fuel bundles in Reactor-1, one bundle got stuck to the upper handling structure, stopping the operations and causing the evacuation and isolation of the reactor's building.
