#Koeberg #misinformation: So it turns out there was actually nothing wrong with cooling water pump that circulates sea-water to the condenser at Unit 1 in the tertiary water loop of @Eskom_SA's Koeberg nuclear power plant. And the pump did NOT have to be repaired after all. 
@Eskom_SA In reality, there was nothing wrong with the pump. It tripped out as it should when there was a low water level in the suction inlet pit, caused by an ingress of marine life to the inlet drum screen, which tripped due to high torque, resulting in the low suction pit water level.
@Eskom_SA Even the tripping of 1 of the 3 sea water circulating pumps of Unit 1 should not have caused the reactor to shut down. But the heat exchanger on the Unit 1 condenser was due for maintenance and was not able to handle the secondary-side heat load with 1 of 3 pumps out of service.
