The Augusta Chronicle reported this afternoon:
Plant Vogtle’s Unit 1 nuclear reactor was unexpectedly shut down Saturday after a sensor indicated an issue with a water pump.
The unit remained offline Sunday while an incident response team explored the cause, Southern Nuclear spokesman Mark Sullivan said.
It is unclear from the press coverage whether the shutdown was automatic or if operators scrammed the reactor. A press release from Southern Co., owner of Vogtle, does nothing to clarify this point, as it simply notes that plant operators ” took the unit offline.” The release seems to want to have it both ways, saying: “All Plant Vogtle safety systems operated as designed, and operators responded as they are trained in a professional and safe manner.”
Southern Co. recently gained approval for two additional reactors at Vogtle.
