The 1,100-MW Vogtle Unit 2 nuclear reactor in Georgia went offline unexpectedly in the pre-dawn hours of May 25 after the water level for a steam generator “began to lower for an unknown reason” according to an event report filed with the Nuclear Regulatory Commission (NRC).
Southern (NYSE:SO) utility Georgia Power is investigating the cause of the incident, which occurred shortly after 2 a.m. on May 25. Unit 2 was listed at zero generation early May 25, according to NRC’s daily reactor status report.
Unit 1 was listed at 100% generation.
The dual-unit station will be home to four reactors in a few years when Georgia Power and its partners complete the construction of Vogtle Units 3 and 4.
