According to Eskom:
(1) It has become the norm in the nuclear industry to replace steam generators that have Alloy 600 Mill Annealed tubing (Koeberg-type). Most utilities that operate pressurized water reactor (PWR) nuclear power plants with this kind of steam generator have replaced or are planning to replace their steam generators. Similarly, Eskom has investigated this situation and determined that it is appropriate to replace the steam generators. Given the processes required in replacement of such equipment and scheduled outages every 18 months, Eskom has decided to commence on the process at this stage. 

(a) There are three (3) steam generators for each of the two units at Koeberg – i.e. a total of six (6) steam generators. The project envisages that all three steam generators on each unit respectively will be replaced during a scheduled re-fuelling, inspection and maintenance outage.  

(b) The replacement of the steam generators is a multi-billion rand project. The commercial process will determine the cost for the entire project.

(c) The procurement process has commenced. At this stage it is envisaged that the steam generators could be replaced during scheduled outages in 2016 and 2017. The actual outage when the steam generators will be replaced in each of the two units respectively is dependent on the outcome of the commercial negotiations and the schedule contracted with the chosen suppliers. 

(2) The procurement is sizeable and complex. Eskom is currently on track with the process as mentioned in (1)(c) above. Following the necessary key approvals, the procurement process has commenced as mentioned above.
