Eskom Koeberg Unit 1 undergoes routine maintenance


Koeberg Nuclear Power Station Unit 1, situated in Cape Town, South Africa has been shut down today, 26 February 2018, for a refuelling outage.

The unit is expected to return to service at the end of May 2018.

“Koeberg Unit 2 is currently operating optimally and is contributing 930 MW to the national grid. Every 15 to 18 months a unit is shut down for refuelling, maintenance and statutory inspections. Outages are scheduled to avoid having both units out of service at the same time. This routine maintenance is part of Eskom’s overall maintenance programme for its generation units,” says Velaphi Ntuli, Koeberg Power Station Manager.

“During these routine outages, one third of the used nuclear fuel is replaced with new fuel. Maintenance, plant modifications, inspections and statutory work is done to ensure that international safety standards continue to be met and that reliable plant performance continues,” continues Ntuli.

Unit 1 currently holds a record of running for 400 days without being interrupted, a milestone that was achieved in December 2017.

Koeberg, Africa’s only nuclear power station, has an installed capacity of 1 860 MW, which provides 50% of the Western Cape’s and approximately 5.6% of South Africa’s energy needs. It has operated safely and efficiently for 33 years.
