Amid ongoing delays in returning Koeberg Unit 2 to service, as well as delays to the steam generator replacement (SGR) programme across both Koeberg’s reactors, Eskom has announced the resignation of its chief nuclear officer, Riedewaan Barkadien. COO Jan Oberholzer said on Monday that Barkadien, who has worked at Eskom for 27 years, would depart on July 31 to join a Canadian nuclear utility in an executive position.
