Tuesday, 18 April 2017: Unit 2 of the Koeberg power station was shut down yesterday for a
scheduled refueling outage after a record 492 days of uninterrupted run.
The refuelling outage is planned for about 2 months
and Unit 2 is expected back on line by May 2017. The unit has been on stream
without major interruption since December 2015, following its previous outage.
Koeberg Unit 1 is currently operating optimally and is
contributing 930MW to the national grid.
Every 15 to 18 months, each of the two units at
Koeberg is shut down for refuelling, inspection and maintenance. This routine
maintenance is part of Eskom’s overall maintenance programme for its fleet of
generation units. Outages are scheduled so as to avoid having both units out of
service at the same time and to avoid the winter months in each year.
During these routine outages, one third of the used
nuclear fuel is replaced with new fuel. Maintenance, plant modifications,
inspections and statutory work to ensure that international safety standards
continue to be met and that reliable plant performance continues, are
