South Africa’s Koeberg Nuclear Power Station became fully offline after Unit 1 safely shut down following a turbine trip.

South African state-owned utility Eskom said Koeberg Nuclear Power Station Unit 1 shut down safely under established procedures after a turbine trip during the early hours of August 27. With Unit 1 no longer supplying electricity, the nuclear station was temporarily fully offline.

Eskom said Unit 1’s removal from the grid did not pose a risk to South Africa’s national electricity supply. The utility described the grid as continuing to operate safely and stably.

The event had no effect on nuclear safety and posed no risk to employees, the public, or the environment, according to Eskom’s statement. The cause of the turbine trip remained under investigation.
