The steam generator replacement project, which is central to Eskom’s R20-billion programme to extend the 40-year design life of the Koeberg nuclear power station by a further 20 years, marked a major milestone this week with the arrival of the first units in Cape Town. The project, which was sanctioned by the Eskom board in 2010 and approved by the National Nuclear Regulator, involves the replacement of all six steam generators at Koeberg’s two units.
