The return of Koeberg’s Unit 1 to commercial service has been delayed by a further 10 days as some critical tests are still to be completed before the reactor is started. The last date that Eskom provided for the return of Unit 1 from the extension of life project was 3 November. It is now expected to be returned around 13 November. Unit 2 will then be taken offline to replace its steam generators. The extension project will give Koeberg a 20-year extension of its licence, which expires in July 2024.
