Eskom says the Nuclear One Reactor at the Koeberg Nuclear Station in Cape Town will be returned to service by the weekend.
The reactor tripped on Monday at 16:30, due to a fault on the electrical breaker to one of the primary coolant pumps.
“Eskom can confirm that the reactor was then safely shut down by the operators, in compliance with the operating procedure.”
“Initial fault-finding ruled out any concerns on the primary pump or the motor itself. There are no nuclear safety concerns.”
“By mid-morning yesterday, the cause of the trip had been confirmed to be a faulty electrical protection relay, which tripped the primary motor. The secondary side was already fully conditioned and on standby, waiting for the reactor and the primary system to returned to service,” the power utility said in a statement.
Additionally Eskom said the unit will be returned to service once an assessment of the protection relay is completed together with an analysis of the incident.
