Shortly after midnight on 28 October 2021 some test results became available which found excessive levels of Iodine-131 in the ventilation system at the Koeberg nuclear power station. This was likely a result of a test which had been done in the afternoon, combined with faulty filtration systems that meant the Koeberg Security Central Alarm Station (CAS) had to be evacuated.
While it is reassuring that Eskom were testing this safety system, no standard test procedure includes evacuating all staff from the security nerve centre of a nuclear plant. Clearly there was something significantly wrong.
While Eskom has not released much by way of detail, it is likely to be a result of a combination of three factors.
The National Energy Regulator of South Africa (NERSA) has given a conditional concurrence with the section 34 ministerial determination to proceed with procuring a new nuclear plant. This concurrence has some crucial suspensive conditions, in particular 1.3. This makes it clear that given the information put before NERSA, the decision to go ahead with a nuclear build cannot be considered rational.
It was recently widely reported in the media that a US-based engineering company has been awarded a portion of a R20bn contract to extend the life of the Koeberg nuclear power plant. Activists and civil organisations are concerned that the legal processes required to grant a licence for a life extension have not been followed.
Koeberg’s nuclear licence expires in 2024
In order to operate beyond 2024, Eskom needs the approval of the NNR, and a new licence to be issued. This licencing process is described in new regulations published in March 2021, which requires a notice in the government gazette as well as announcements in local newspapers. This would allow the public to make comments for the NNR to take into account before making a decision. However, it appears that this process has not been followed.
The KAA has noted recent media reports that claim Jacobs Engineering Group has secured a contract to extend the life of the Koeberg nuclear power plant.
Koeberg is operated by Eskom, under a licence from the National Nuclear Regulator (NNR) which expires in July 2024. In order to operate beyond that date, Eskom needs the approval of the NNR for the life extension, and a new licence to be granted. This licencing process requires a public participation process which the NNR is obliged to take into account before making a decision.
The fact that this contract has been announced before the NNR has indicated it has even received the life extension application from Eskom is deeply concerning. The NNR has the mandate to protect the public, but to allow Eskom to ignore due process and make this announcement as if the extension is a ‘done deal’ calls into question the independence of the NNR.
All eyes were on Minister Gwede Mantashe today to see what he had to say about nuclear power issues as he presented the budget for his Department of Mineral Resources and Energy (DMRE). In a surprising move, he did not mention the subject.
However, last week on 12 May addressing the National Council of Provinces (NCOP), Mantashe responded to questions about the Koeberg nuclear power plant. According to academics, activists and organisations, Mantashe’s answers contained disinformation that implied that Koeberg’s 20-year life extension is approved, and that the cost of the electricity it produces is a fraction of what it actually is.
In response to our press release Cracks in Koeberg Safety Claims Eskom released a statement (full text given below) on 12 February 2021. This statement ignores several of the issues we raised, obfuscates others, and provides some further alarming information.
Maintenance and testing is being done … The Eskom statement says “repairs have been implemented” which sounds initially reassuring. However, the report itself describes the repairs in progress at the time as follows:
