“Koeberg Unit 1 tripped on Sunday morning as a result of a fault on a feedwater pump, which is on the secondary plant. The plant was shut down in accordance with standard plant operating procedures and all parameters are stable. There are no nuclear safety concerns on the reactor side of the plant, which is ready to be restarted once the feedwater pump fault has been resolved.”
An investigation into the faulty feedwater pump was under way and only when concluded will Eskom be able to confirm when the unit will be repaired and ready to return to service — “expected to be during next week”.
Eskom said service units at the Tutuka and Hendrina power stations as well as two Kusile units have also returned to service in the past 24 hours.
“Unfortunately, we have taken off a unit each at Hendrina and Kriel power stations, in addition to the Koeberg unit. Total breakdowns currently amount to 15 813MW while planned maintenance is 4 967MW of capacity. Eskom would like to apologise for the inconvenience caused by the implementation of load-shedding, and asks that people reduce their usage in order to help us through the constraints,” the power giant said.
Once more details are clear, Eskom will communicate any changes to the power plan.
